Description

Technical Field

[0001] The utility model relates to the application field of railway locomotive vehicle foundation brake, in particular to an assembly production line of a clamp unit brake cylinder. Background Art

[0002] At present, there are about 3,500 EMUs in stock. In recent years, the output of newly built EMUs has been stable, and the annual growth rate of repaired EMUs has reached more than 20%. With the continuous development of the repair business, the repair business has also been continuously expanded. At the same time, customers' requirements for the repair process level, quality capability, repair cycle, repair cost, and repair data of the brake caliper unit have also been continuously improved. At present, the assembly process of the brake caliper unit has problems such as low degree of automation and low degree of data digitization. Therefore, based on the analysis of the brake cylinder assembly process and beat, by developing a brake cylinder digital assembly production line, it is possible to not only improve the automation and digitization of the brake caliper repair process, but also improve the data collection and analysis capabilities of the assembly process, and ultimately improve the overall technical level of the brake caliper.

[0003] Currently, the assembly of caliper brake cylinders is mainly carried out at a single workstation, which has high labor intensity and low levels of automation and digitization in the assembly process.

[0004] The assembly of the brake cylinder includes two parts: pre-assembly and final assembly. The pre-assembly includes the cylinder body, piston, clearance adjuster, connecting rod, parking cylinder, hand relief, etc. The final assembly assembles the pre-assembled components in sequence to form a brake cylinder. The assembly process is carried out at a single station. There is no connecting equipment between the stations. All materials need to be manually carried, which is labor-intensive. There is no information entry equipment at the station. It needs to be filled in manually, which is prone to errors and has a low degree of digitization. For the overhauled products, it is necessary to ensure that the disassembled parts are qualified before being assembled back to the original clamp, that is, the single-set flow overhaul mode. For a single-set flow, matching parts with clamps is a very tedious task. When the clamps are disassembled, the parts need to be distinguished and managed, and they need to be assembled into the clamps corresponding to their numbers after they are qualified. In this process, it is very easy to confuse the springs, resulting in the inability to correspond one-to-one between the springs and the clamps, which brings inconvenience to the overhaul work. Utility Model Content

[0187] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0188] like Figures 1 to 64As shown, the present application provides a clamp unit brake cylinder assembly production line, including a double-layer automatic conveyor line, the double-layer automatic conveyor line includes an upper conveyor line and a lower conveyor line arranged at intervals from top to bottom, and a cylinder tray 1300 for placing a common cylinder body 09 of the brake cylinder, the cylinder tray 1300 can circulate along the circular conveying direction of the double-layer automatic conveyor line; along the conveying direction of the upper conveyor line, a cylinder bushing pressing device 600, a cylinder feeding device 700, a cylinder injection device 800, a front end cover assembly device 1000 and a connecting rod assembly device 1200 are sequentially arranged, and the cylinder bushing pressing device 600 The cylinder block oil injection equipment 800 is located on the first side of the double-layer automatic conveyor line, and the cylinder block loading equipment 700, the front end cover assembly equipment 1000 and the connecting rod assembly equipment 1200 all have work tables and return tables spaced apart upper and lower. The parts in the upper conveyor line are respectively fixed on the corresponding work tables in the cylinder block loading equipment 700, the front end cover assembly equipment 1000 and the connecting rod assembly equipment 1200, and the parts in the lower conveyor line are respectively fixed on the corresponding return tables in the cylinder block loading equipment 700, the front end cover assembly equipment 1000 and the connecting rod assembly equipment 1200.

[0189] The working surfaces of the cylinder loading equipment 700, the front end cover assembly equipment 1000 and the connecting rod assembly equipment 1200 are also provided with inclined pre-loading material chutes 1500, and the pre-loading material chute 1500 is arranged inclined downward from the second side of the double-layer automatic conveyor line to the first side; the piston assembly equipment 100 and the connecting rod assembly equipment 500 are spaced apart on the second side of the double-layer automatic conveyor line.

[0190] Among them, the piston assembly equipment 100 and the connecting rod assembly equipment 500 on the second side of the double-layer automatic conveyor line are pre-installation stations, which are used to pre-install some parts first; the cylinder loading equipment 700, the front cover assembly equipment 1000 and the connecting rod assembly equipment 1200 on the double-layer automatic conveyor line, and the cylinder bushing equipment 600 and the cylinder oil injection equipment 800 located on the first side of the double-layer automatic conveyor line are assembly stations, and the pre-installed pre-installed parts can slide along the corresponding pre-installed material slide 1500 to the assembly station, which makes feeding more convenient. At each assembly station, each pre-installed part can be assembled on the cylinder, and the structure is compact. The cylinder tray 1300 circulates on the upper and lower conveyor lines along the circular conveying direction of the double-layer self-conveying conveyor line, and each station cooperates closely, which improves the installation efficiency.

These devices are introduced separately as follows:

[0193] Reference Figure 2 The piston assembly device 100 mainly includes a main piston press-fit device 101, a first rotary oil injection device 102 and a guide nut press-fit device 103, which are specifically as follows:

[0194] The main piston press-fit device 101 is used to press-fit the first leather cup of the brake cylinder onto the main piston 011 of the main piston assembly 01. For details, refer to Figures 3 to 6 The main piston press-fitting device 101 includes a main piston press-fitting assembly and a main piston positioning frame 1014. The main piston press-fitting assembly includes a first support frame 1011, a first pressure head 1012 with a receiving groove at the bottom, and a first driving device 1013; the first pressure head 1012 and the main piston positioning frame 1014 are arranged on the first support frame 1011 at an interval and coaxially, and the main piston positioning frame 1014 is used to center and position the main piston component 01 of the brake cylinder. A first magnet is embedded in the bottom surface of the first pressure head 1012. The bottom surface of the first pressure head 1012 can adsorb the bottom of the annular groove of the first leather cup of the brake cylinder through the first magnet, and the inner ring of the first leather cup can be accommodated in the receiving groove. The first driving device 1013 is connected to the first pressure head 1012 and can drive the first pressure head 1012 to move up and down.

[0195] Among them, the structure of the main piston component 01 is an existing structure, which includes a bowl-shaped main piston 011, a main piston cylinder 012 and a first leather cup. The main piston 011 is roughly bowl-shaped, and has an integrally connected main piston inner sleeve inside. The main piston inner sleeve has an internal thread and can be threadedly connected to the end of the main piston cylinder 012. The first leather cup is an annular structure with an annular groove formed by an outer ring, an inner ring and a circular ring between the outer ring and the inner ring. It is a rubber part with a metal skeleton. When assembling, the main piston 011 is first connected to the main piston cylinder 012, and then the annular first leather cup needs to be pressed and set on the main piston 011, and the outer wall of the bottom of the annular groove of the first leather cup is close to the bowl edge of the main piston 011. The brake cylinder mentioned in this article is an air brake. When working, the air acts on the first leather cup to provide thrust, thereby pushing the main piston 011 forward to generate braking force.

[0196] In the prior art, when assembling the leather cup on the main piston 011, the main piston 011 is simply placed randomly and the leather cup is pressed by a press, without positioning the main piston 011 and the leather cup. It is difficult to align the leather cup during installation, and the two are easily out of center and deviate, which affects the braking performance of the product.

[0197] In this embodiment, the first leather cup is pressed onto the main piston 011 by the main piston press-fitting device 101. During assembly, the main piston assembly 01 is placed in the main piston positioning frame 1014 to achieve the centering positioning of the main piston assembly 01; the first leather cup is placed with the notch of the annular groove facing upward, so that the inner wall of the bottom of the annular groove is magnetically adsorbed on the bottom surface of the first pressure head 1012, the inner ring of the first leather cup is inserted into the receiving groove of the first pressure head 1012 and abuts against the inner wall of the receiving groove, and the outer ring of the first leather cup abuts against the outer wall of the receiving groove of the first pressure head 1012. Then, the first driving device 1013 is used to drive the first pressure head 1012 to move downward, driving the first leather cup to move downward, and after the first leather cup is sleeved on the main piston 011, the first pressure head 1012 continues to press downward, and the first leather cup is tightly sleeved on the main piston 011 and the outer wall of the bottom of the annular groove of the first leather cup abuts against the bowl-shaped bowl edge of the main piston 011. Then the first driving device 1013 drives the first pressing head 1012 to move upward, so that it can be separated from the first leather cup, and the press-fitting of the main piston leather cup is completed.

[0198] By ensuring that the first pressure head 1012 and the main piston positioning frame 1014 are concentrically arranged, the first leather cup is ensured to be concentric with the first pressure head 1012 during installation, and the main piston assembly 01 is aligned and positioned by using the main piston positioning frame 1014, it can be ensured that when the first leather cup is pressed down, the first leather cup is aligned with the main piston 011, and the concentricity of the first leather cup and the main piston 011 is ensured; at the same time, since the outer wall of the main piston 011 is an inverted cone surface, when the first leather cup is pressed down, the inverted cone surface and the leather cup are used to cooperate, which also has a self-positioning effect, thereby effectively ensuring the concentricity of the main piston leather cup press-fitting. The first pressure head 1012 is equipped with a strong magnet that can absorb the leather cup to ensure that the leather cup is accurately positioned. When the entire device is used, the staff only needs to place the main piston assembly 01 in the main piston positioning frame 1014, absorb the first leather cup on the first pressure head 1012, and then use the first drive device 1013 to drive the first leather cup to be pressed down, which is simple and convenient.

[0199] Further, in order to facilitate the centering and positioning of the piston positioning frame on the main piston assembly 01, refer to Figure 3-Figure 6 The main piston positioning frame 1014 includes a first upper plate 10141 and a first lower plate 10142 spaced apart from each other, and a plurality of first connecting columns 10143 connected between the first upper plate 10141 and the first lower plate 10142; the first upper plate 10141 has a first central hole 101411 at its center, and a notch 101412 communicating with the first central hole 101411 and the edge of the first upper plate 10141 is formed on the first upper plate 10141 (the notch 101412 is connected to the first central hole 101411 and the edge of the first upper plate 10141). The circular center hole is formed by extending both ends of its diameter to the edge of the upper plate body); at the bottom of the first upper plate body 10141, there are two lateral push rods 10144 that are arranged opposite each other and can elastically extend and retract, and the axes of the lateral push rods 10144 are perpendicular to the center line of the notch 101412; the main piston assembly 01 can be pushed into the first upper plate body 10141 through the notch 101412, and the ends of the two lateral push rods 10144 can rest against the outer wall of the main piston assembly 01 (specifically, against the side wall of the main piston cylinder 012).

[0200] The first center hole 101411 is preferably a circular hole to avoid bumping the main piston assembly 01. When in use, the main piston assembly 01 is pushed into the first upper plate 10141 through the notch 101412, so that the main piston assembly 01 is roughly in the center position (the bowl edge of the main piston 011 abuts on the top surface of the first upper plate 10141), and at the same time, the two lateral push rods 10144 on the left and right sides abut against the main piston cylinder 012, which can ensure that the main piston assembly 01 is aligned left and right, thereby achieving basic centering positioning of the main piston assembly 01.

[0201] It can be understood that for different brake cylinders, the main piston assembly 01 has different size specifications. The size of the first center hole 101411 and the notch 101412 should ensure that the main piston assembly 01 with the largest diameter can also be placed therein. The gap between the two transverse push rods 10144 when they are in a freely extended state should be smaller than the minimum specification diameter of the main piston cylinder 012. The gap between the two transverse push rods 10144 when they are in a retracted state should be larger than the maximum specification diameter of the main piston cylinder 012. When the device is applied to main piston assemblies 01 of different sizes, even if the main piston positioning frame 1014 does not completely align the main piston assembly 01, it will not deviate too much due to the action of the two transverse push rods 10144. Then, by utilizing the guiding effect of the inverted conical surface on the main piston 011 when pressed down and the self-positioning function of the first leather cup when pressed down, the centering press installation of the main piston 011 and the first leather cup can be well achieved.

[0202] In order to facilitate the elastic expansion and contraction of the transverse push rod 10144, a fixed body 10145 is fixedly provided at the bottom of the first upper plate 10141, and the first end of the transverse push rod 10144 can be axially slidably inserted in the slide groove of the fixed body 10145, and a first return spring is clamped between the first end of the transverse push rod 10144 and the fixed body 10145, and the second end of the transverse push rod 10144 is connected to the roller 10146, and the axis of the roller 10146 is arranged along the vertical direction.

[0203] The fixed body 10145 here can be a plate-shaped structure, and the two ends of the first return spring respectively press against the first end of the transverse push rod 10144 and the bottom of the slide groove, and a limiter 10372 is provided at the notch end of the slide groove to prevent the transverse push rod 10144 from being separated from the fixed body 10145. The roller 10146 design is adopted, and in the process of pushing the main piston assembly 01 from the notch 101412 into the first upper plate body 10141, the force is smaller, and the movement of the main piston assembly 01 is smoother.

[0204] Furthermore, an oil injection hole penetrating through the bottom surface of the first pressure head 1012 is provided in the first pressure head 1012 , and a pipe joint 10121 communicating with the oil injection hole is provided on the first pressure head 1012 , and the first lower plate 10142 is rotatably connected to the first support frame 1011 .

[0205] Only one of the above-mentioned oil spray holes is required, and one of the pipe joints 10121 is also required, and the pipe joint 10121 is connected to the corresponding grease tank through the corresponding pipe. The bottom of the first lower plate 10142 can be connected to the first support frame 1011 through a bearing for manual rotation. After the first leather cup is pressed against the main piston 011, the first driving device 1013 is used to drive the first pressure head 1012 to be raised a little, and then the first lower plate 10142 is manually rotated to drive the first leather cup to rotate, and grease can be sprayed onto the surface of the first leather cup through the oil spray hole; generally, manually rotating the first lower plate 10142 once is sufficient.

[0206] Since the amount of grease required for the first leather cup is greater than that required for the inner and outer surfaces of the main piston 011, after the leather cup of the main piston 011 is pressed and installed, before both are taken out, the first lower plate 10142 is manually rotated directly, and the first leather cup is sprayed with oil using the oil spray hole provided on the first pressure head 1012, which makes the operation more convenient.

[0207] Furthermore, at least one hand valve is provided on the first support frame 1011, each hand valve is connected to a corresponding grease tank through a corresponding pipeline, and a corresponding pump is provided on the corresponding pipeline, and one of the hand valves is connected to the pipeline connector 10121 through a corresponding pipeline. In this way, different types of grease can be stored in each grease tank, and when a certain type of grease needs to be sprayed, the hand valve corresponding to the grease tank is connected to the pipeline connector 10121 through a pipeline, and the grease can be sprayed on the first leather cup, which is more versatile.

[0208] For ease of processing and installation, refer to Figure 3 The first pressure head 1012 includes a connecting plate 10122 and a pressing ring 10123 arranged at intervals in the upper and lower directions (generally, the outer diameter of the pressing ring 10123 is larger than the diameter of the connecting plate 10122), and a plurality of oblique ribs 10124 are connected circumferentially at intervals between the connecting plate 10122 and the pressing ring 10123. The space enclosed by the connecting plate 10122, the pressing ring 10123 and the plurality of oblique ribs 10124 constitutes the above-mentioned receiving groove. A plurality of insertion grooves are circumferentially opened in the bottom surface of the pressing ring 10123, and the first magnet includes a plurality of magnetic blocks, which are respectively inserted and fixed in the corresponding insertion grooves.

[0209] The first driving device 1013 can be, for example, a cylinder, the piston rod of which is vertically arranged and the bottom end of which is fixedly connected to the connecting plate 10122 of the first pressing head 1012, so as to drive the first pressing head 1012 to move up and down. A first switch 10131 is also arranged on the first supporting frame 1011, and the first switch 10131 is used to control the action of the cylinder. The first switch 10131 can be, for example, a hand valve, and the operator can manually operate the hand valve to control the cylinder to move up or down.

[0210] The first rotary oil spraying device 102 is used to spray oil on the main piston assembly 01 after the leather cup is assembled. Figure 7 and Figure 8 The first rotary oil spraying device 102 includes a protective cover 1021 with an opening on one side, a chassis 1022 rotatably arranged at the bottom of the protective cover 1021, and a driving member 1023 for driving the chassis 1022 to rotate. An oil pumping device 1024 is provided on the side of the protective cover 1021 facing the opening, and a socket 10211 connected to the opening is provided on the top surface of the protective cover 1021.

[0211] The driving member 1023 can be, for example, a motor, and a foot switch can be used to control the operation of the motor; the motor is arranged outside the bottom of the protective cover 1021, and the output shaft of the motor passes through the bottom of the protective cover 1021 and is connected to the base. The rotation of the chassis 1022 is achieved by rotating the motor, which is simple and convenient. The oil spraying device is suitable for oil spraying of rotating parts, can ensure the uniformity of spraying, and is convenient for personnel to spray oil.

[0212] Generally, a positioning groove is provided on the chassis 1022 , and the main piston cylinder 012 can be inserted into the positioning groove to position the main piston assembly 01 .

[0213] When in use, the main piston assembly 01 after assembling the first leather cup is placed on the chassis 1022 with the opening of the protective cover 1021 facing upwards, and the main piston cylinder 012 is inserted and positioned in the positioning groove. The entire main piston assembly 01 is located in the protective cover 1021, that is, the top of the main piston assembly 01 will not exceed the above-mentioned socket 10211. The operator steps on the foot switch, and the motor drives the main piston assembly 01 to rotate. During the rotation of the main piston assembly 01, the operator holds the oil gun and aims at the socket 10211 to spray oil on the outer surface of the main piston 011; during installation, the opening of the protective cover 1021 faces the vertical frame described below, so that the opening of the protective cover 1021 faces away from the operator. The setting of the protective cover 1021 can prevent grease from splashing on the operator, and the oil extraction device 1024 (such as a range hood) can remove oil smoke during the oil spraying process. Generally, during this process, the main piston cylinder 012 is not sprayed with oil first, so that the operator can hold the main piston cylinder 012 and take it out.

[0214] Compared with the prior art in which the main piston component 01 after the leather cup is assembled is manually rotated to spray oil without any fume extraction measures, the first rotary oil spraying device 102 is used in this embodiment to save time and effort during the oil spraying operation and is more environmentally friendly.

[0215] The guide nut press-fitting device 103 is used to press the retaining ring into the slot of the guide nut 021, referring to Figures 9 to 13The guide nut pressing device 103 includes a guide nut pressing assembly and a guide nut positioning member 1038. The guide nut pressing assembly includes a second support frame 1031, a cylindrical second pressing head 1032, a third pressing head 1033, a push rod assembly 1034 and a second driving device 1037; the second pressing head 1032 and the guide nut positioning member 1038 are arranged on the second support frame 1031 with an upper and lower interval, and the guide nut positioning member 1038 is used to center and position the guide nut component 02 of the brake cylinder, the third pressing head 1033 is arranged in the second pressing head 1032 and can be used to set the first retaining ring 025 of the brake cylinder, the push rod assembly 1034 is arranged in the second pressing head 1032 and is located above the third pressing head 1033, and the second pressing head 1032, the third pressing head 1033, the push rod assembly 1034 and the guide nut positioning member 1038 are coaxially arranged.

[0216] The second driving device 1037 is connected to the push rod assembly 1034 and can drive the push rod assembly 1034 to move up and down. In the process of driving the push rod assembly 1034 to move downward, the second driving device 1037 can drive the second pressure head 1032 to move downward through the linkage assembly 1035, and can drive the third pressure head 1033 to move downward through the connecting assembly 1036. It can also drive the push rod assembly 1034 to continue to move downward after the second pressure head 1032 moves to the preset position and the third pressure head 1033 moves to the preset position, so as to push the first retaining ring 025 downward.

[0217] In order to facilitate the downward movement of the push rod assembly 1034 and the second pressure head 1032, refer to Fig.11 The linkage assembly 1035 includes a pressure plate 10351 and a buffer spring 10352. The upper end of the second pressure head 1032 is fixed to the bottom surface of the pressure plate 10351. The driving end 50271 of the second driving device 1037 is fixed to the push rod assembly 1034 through the connecting rod 10371. The connecting rod 10371 can move up and down through the pressure plate 10351. The buffer spring 10352 is sleeved on the connecting rod 10371 and its two ends are respectively pressed between the limiting portion 10372 of the connecting rod 10371 and the top surface of the pressure plate 10351.

[0218] In this embodiment, a first linear bearing 10353 is also fixedly provided at the center hole of the pressure plate 10351. The bottom of the first linear bearing 10353 has a mounting ring with an increased diameter, which rests on the bottom surface of the pressure plate 10351 and is connected to the pressure plate 10351 by fasteners (such as bolts). The second support frame 1031 has a vertically arranged first guide column 10311, and the two ends of the pressure plate 10351 can be mounted on the first guide column 10311 so as to be movable up and down. A groove is provided on the outer periphery of the center hole of the pressure plate 10351, and the two ends of the buffer spring 10352 respectively abut against the limit portion 10372 on the upper part of the connecting rod 10371 and the bottom of the groove. The above-mentioned connecting rod 10371 can be movably provided in the first linear bearing 10353, and the first linear bearing 10353 can play a guiding and protective role in the movement of the connecting rod 10371.

[0219] In order to facilitate the push rod assembly 1034 to move with the third pressure head 1033 when it moves downward, and to enable the push rod assembly 1034 to move relative to the third pressure head 1033 after the third pressure head 1033 moves to a preset position, refer to Fig.11 The connecting assembly 1036 includes a guide plate 10361, a vertical rod 10362 and a cross rod 10363. A side through hole is opened on the side wall of the second pressure head 1032, and the guide plate 10361 passes through the side through hole and is fixedly connected to the connecting rod; the vertical rod 10362 is located on the outer side of the second pressure head 1032, and the upper part of the vertical rod 10362 can slide up and down and pass through the guide plate 10361. A second return spring 10364 is also sleeved on the vertical rod 10362, and the two ends of the second return spring 10364 respectively press between the guide plate 10361 and the bottom step 103621 of the vertical rod 10362; the lower end of the vertical rod 10362 is fixedly connected to one end of the cross rod 10363, and the other end of the cross rod 10363 passes through the side through hole and is fixedly connected to the third pressure head 1033, and the cross rod 10363 can press against the bottom hole wall of the side through hole.

[0220] In order to prevent the guide plate 10361 and the vertical rod 10362 from wearing too fast, the connecting assembly 1036 also includes a second linear bearing 10365, which is inserted into the through hole of the guide plate 10361 and connected to the guide plate 10361 by a fastener (such as a bolt), and the vertical rod 10362 is inserted into the second linear bearing 10365. The second linear bearing 10365 can play a guiding and protective role when the vertical rod 10362 and the guide plate 10361 move relative to each other. The upper end of the second return spring 10364 specifically rests on the bottom surface of the second linear bearing 10365.

[0221] In order to facilitate the push rod assembly 1034 to push the retaining ring, the push rod assembly 1034 includes a fixed block 10341 fixed to the bottom end of the connecting rod 10371 and a plurality of vertical push rods 10342 fixed to the bottom surface of the fixed block 10341 at circumferential intervals.

[0222] The structure of the guide nut component 02 is an existing structure. On the one hand, it is used to cooperate with the lead screw 083 of the brake cylinder to transmit the braking force; on the other hand, it is used to cooperate with the lead screw 083 to adjust the gap between the clamp and the wheel when the vehicle is braked. Fig.12 The guide nut component 02 includes a hollow guide nut 021, a guide tooth seat 022 sleeved and fixed on the middle part of the guide nut 021, an annular spring seat 023 sleeved on the end of the guide nut 021, and a guide spring 024 is provided on the outer sleeve of the guide nut 021, and the two ends of the guide spring 024 are respectively pressed against the guide tooth seat 022 and the spring seat 023; an annular groove is provided on the outer wall of the end of the guide nut 021, and a first retaining ring 025 can be clamped in the groove; the first retaining ring 025 is an open ring, which is a metal retaining ring, used to axially limit the spring seat 023.

[0223] In order to facilitate positioning of the guide nut assembly 02, the guide nut positioning member 1038 includes a first positioning column 10381, and the inner hole of the guide nut 021 in the guide nut assembly 02 can be sleeved on the first positioning column 10381. The outer diameter of the first positioning column 10381 matches the inner hole diameter of the guide nut 021 to achieve centering of the guide nut assembly 02.

[0224] In order to ensure the alignment of the first retaining ring 025 and the guide nut 02 and to facilitate the sleeve installation of the first retaining ring 025, refer to Fig.11 The third pressure head 1033 includes a conical block 10331 and a cylindrical block 10332 connected up and down. The outer wall of the conical block 10331 is used to fit the first retaining ring 025. The cylindrical block 10332 can be inserted into the inner hole of the guide nut 021 and the bottom surface of the conical block 10331 can rest on the top surface of the guide nut 021.

[0225] Since the first retaining ring 025 is relatively hard, it is relatively laborious for the operator to manually expand it. In this embodiment, the diameter of the small diameter end of the conical block 10331 should match the inner diameter of the first retaining ring 025 in a natural state, and the diameter of the large diameter end should be larger than the outer diameter of the guide nut 021. The diameter corresponding to the position of the above-mentioned multiple vertical push rods 10342 should be greater than or equal to the outer diameter of the large end of the conical block 10331. When in use, the first retaining ring 025 is directly sleeved on the small diameter end of the conical block 10331. When the third pressure head 1033 moves to the preset position and the vertical push rods 10342 continue to move downward, each vertical push rod 10342 can abut against the end surface of the first retaining ring 025 and push the first retaining ring 025 downward. During the downward pushing process, the first retaining ring 025 moves downward from the small diameter end to the large diameter end of the conical block 10331 and is continuously expanded. Then, the first retaining ring 025 is separated from the conical block 10331 and pushed into the slot of the guide nut 021.

[0226] In the prior art, when installing the retaining ring, a press machine is used to press the spring seat 023 to expose the slot, and then the retaining ring is manually installed, which is time-consuming and laborious. In the present application, the driving device 3015 can be used to achieve one-step press installation, without manual installation, and can ensure that the guide nut 021 and the retaining ring are aligned, so the installation efficiency is higher.

[0227] When the guide nut pressing device 103 is in the initial position, that is, Fig.10 and Fig.11 In the state shown, the buffer spring 10352 and the second return spring 10364 are both in a slightly compressed state, and the bottom surface of the first linear bearing 10353 rests on the top surface of the guide plate 10361; the second return spring 10364 is also in a slightly compressed state, and the cross bar 10363 rests on the bottom hole wall of the side through hole of the second pressure head 1032 under the action of the elastic force of the second return spring 10364.

[0228] The guide nut press-fitting device 103 is used to press-fit the first retaining ring 025 into the slot of the guide nut 021. The press-fitting process is as follows:

[0229] Put the guide nut assembly 02 on the first positioning column 10381, and put the first retaining ring 025 on the small diameter end of the conical block 10331 of the third press head 1033 (as needed, the first retaining ring 025 can also be installed after the third press head 1033 moves to the preset position); use the second driving device 1037 to drive the connecting rod 10371 to move downward, and drive the push rod assembly 1034 to move downward together; due to the existence of the linkage assembly 1035, the pressure plate 10351 and the second press head 1032 will move downward together; at the same time, due to the existence of the connecting assembly 1036, the third press head 1033 will also move downward together.

[0230] When the second pressure head 1032 contacts the spring seat 023 of the guide nut 021, it will continue to move downward, driving the spring seat 023 to move downward together; when the second pressure head 1032 moves to the preset position, that is, the first slot is exposed, the second pressure head 1032 no longer moves, and the pressure plate 10351 also no longer moves; if the third pressure head 1033 also moves to the preset position at this time (that is, the cylindrical block 10332 of the third pressure head 1033 is inserted into the inner hole of the guide nut 021 and the bottom surface of the conical block 10331 is against the top surface of the guide nut 021), the third pressure head 1033 no longer moves. When the second pressure head 1032 moves to the preset position, if the third pressure head 1033 has not moved to the preset position at this time, since the third pressure head 1033 can move up and down relative to the second pressure head 1032, as the connecting rod 10371 continues to move downward and under the elastic force of the second return spring 10364, the third pressure head 1033 will move to the preset position and the third pressure head 1033 will no longer move.

[0231] Afterwards, the connecting rod 10371 drives the push rod assembly 1034 to continue moving downward, compressing the buffer spring 10352, and driving the guide plate 10361 to move downward together. The guide plate 10361 moves downward relative to the vertical rod 10362 and compresses the second return spring 10364, and the guide plate 10361 moves downward relative to the first linear bearing 10353, and the first linear bearing 10353 is separated from the guide plate 10361; the multiple vertical push rods 10342 of the push rod assembly 1034 push the first retaining ring 025 downward, expand the first retaining ring 025 and push it into the slot to complete the press-fitting process.

[0232] Afterwards, the second driving device 1037 drives the connecting rod 10371 to move upward, driving the push rod assembly 1034 and the guide plate 10361 to move upward together. When the guide plate 10361 moves up to rest against the first linear bearing 10353, the buffer spring 10352 and the second return spring 10364 both return to their initial state. Then, the connecting rod 10371 will drive the second pressure head 1032 and the third pressure head 1033 to move upward as a whole until they return to their initial position.

[0233] Reference Fig.14 The wedge assembly device 200 includes a gap adjuster press-fit device 201, a parking cylinder press-fit device 202 and a wedge installation device 203, which are specifically as follows:

[0234] The clearance adjuster press-fit device 201 is used to press-fit the retaining ring into the slot of the clearance adjuster 03. Figure 15-17The clearance adjuster press-fitting device 201 includes a clearance adjuster press-fitting assembly and a clearance adjuster positioning piece 2011. The structure of the clearance adjuster press-fitting assembly is the same as that of the guide nut press-fitting assembly. The second pressing head 1032 of the clearance adjuster press-fitting assembly and the clearance adjuster positioning piece 2011 are arranged on the second support frame 1031 of the clearance adjuster press-fitting assembly at an upper and lower interval. The clearance adjuster positioning piece 2011 is used to center and position the clearance adjuster 03 of the brake cylinder. The third pressing head 1033 is used to fit the second retaining ring of the brake cylinder. The second pressing head 1032, the third pressing head 1033 and the push rod assembly 1034 of the clearance adjuster press-fitting assembly are coaxially arranged with the clearance adjuster positioning piece 2011.

[0235] The clearance adjuster 03 here is an existing structure, and its function is the same as that of the above-mentioned guide nut component 02. On the one hand, it is used to cooperate with the lead screw 083 of the brake cylinder to transmit the braking force; on the other hand, it is used to cooperate with the lead screw 083 to adjust the clearance between the clamp and the wheel when the vehicle is braked. The structure of the upper part of the clearance adjuster 03 is the same as that of the upper part of the above-mentioned guide nut component 02. The upper part has a hollow central tube (corresponding to the upper part of the guide nut 021), and a spring seat 023 and a spring are sleeved on the central tube. A groove is opened on the outer wall of the end of the central tube for installing a second retaining ring to axially limit the spring seat 023. The second retaining ring is pressed into the groove of the clearance adjuster 03 using the clearance adjuster press-fitting device 201. The press-fitting process is similar to the press-fitting of the first retaining ring 025 into the groove of the guide nut 021 by the above-mentioned guide nut press-fitting device 103, and will not be repeated here.

[0236] In order to facilitate the positioning of the clearance adjuster 03 , the clearance adjuster positioning member 2011 includes a sleeve with a groove on the top for inserting and placing the clearance adjuster 03 .

[0237] The lower part of the gap adjuster 03 is different from the above-mentioned guide nut assembly 02. The lower part of the above-mentioned guide nut assembly 02 is a hollow structure, while the lower part of the gap adjuster 03 is a shaft structure without an inner hole. Therefore, the gap adjuster positioning member 2011 adopts a sleeve structure with a groove on the top, and when in use, the lower part of the gap adjuster 03 can be directly inserted into the groove.

[0238] The parking cylinder press-fit device 202 is used to press-fit the parking spring of the parking cylinder 04 into the parking cylinder cover 042, referring to Fig.18 and Fig.19The parking cylinder pressing device 202 includes a third support frame 2021, a positioning plate 2022, a fourth pressing head 2023 which is cylindrical and can move up and down, a third driving device 2024 and an alignment column 2025; the fourth pressing head 2023 and the positioning plate 2022 are arranged on the third support frame 2021 with an upper and lower interval, and the positioning plate 2022 is used to place and center the parking cylinder body 041 of the parking cylinder 04; the alignment column 2025 can be used in the parking After placing the parking piston and the parking spring in the parking cylinder body 041 and covering the parking cylinder cover 042 of the parking cylinder 04, they are inserted into the center hole of the parking cylinder cover 042 and the inner hole of the parking piston; the fourth pressure head 2023, the alignment column 2025 and the positioning plate 2022 are coaxially arranged, and the third driving device 2024 is connected to the fourth pressure head 2023 and can drive the fourth pressure head 2023 to move downward to press the upper end surface of the parking cylinder cover 042.

[0239] In order to facilitate the centering of the parking cylinder body 041 by the positioning plate 2022 , a plurality of second positioning posts 20221 are provided on the positioning plate 2022 . The plurality of second positioning posts 20221 can be inserted into a plurality of mounting holes on the parking cylinder body 041 .

[0240] In one of the embodiments, in order to better ensure the alignment of the parking cylinder cover 042 and the parking cylinder body 041 during the press-fitting process, the positioning plate 2022 can rotate around its own axis, and the parking cylinder press-fitting device 202 also includes a plurality of temporary positioning rods 2026. The temporary positioning rods 2026 can be inserted into the corresponding mounting holes corresponding to the upper and lower portions of the parking cylinder body 041 and the parking cylinder cover 042 after the parking piston and the parking spring are placed in the parking cylinder body 041 and the parking cylinder cover 042 is covered.

[0241] Among them, the currently commonly used parking cylinders 04 include a first type parking cylinder and a second type parking cylinder, which are two different types of parking cylinders 04, both of which are existing structures and have the same function, both of which are used for parking brakes; these two types of parking cylinders 04 both include a parking cylinder body 041 and a parking cylinder cover 042, and a parking piston and a parking spring are arranged in the parking cylinder body 041. When actually assembling the brake cylinder, only one parking cylinder 04 needs to be assembled, and a matching parking cylinder 04 is selected according to the type of the brake cylinder.

[0242] The parking cylinder body 041 and the parking cylinder cover 042 both have a center hole (through hole) and a mounting hole. Fig.19As shown, it is generally square and has eight groups of mounting holes, each group of mounting holes includes a mounting hole that axially penetrates the parking cylinder body 041 and a mounting hole that axially penetrates the parking cylinder head 042; four groups of mounting holes are used to pass four bolts to fix the parking cylinder body 041 and the parking cylinder head 042, and the other four groups of mounting holes are used to pass four bolts to fix the parking cylinder 04 and the intermediate body. Therefore, when the cylinder head is pressed by the parking cylinder press-fitting device 202, four temporary positioning rods 2026 are first passed through the four groups of mounting holes used to connect the intermediate body, and after the cylinder head is pressed against the cylinder body, the temporary positioning rods 2026 are removed after the bolts are installed in the four groups of mounting holes used to connect the cylinder body and the cylinder head.

[0243] For the second type of parking cylinder, it is generally cylindrical and has four groups of mounting holes for inserting four bolts to fix the parking cylinder 04 to the intermediate body. Each group of mounting holes includes a mounting hole (blind hole) that does not penetrate the parking cylinder body 041 in the axial direction and a mounting hole (through hole) that penetrates the parking cylinder cover 042 in the axial direction. The cylinder body and the cylinder cover are fixed by corresponding clamping rings. Therefore, when the cylinder cover is pressed by the parking cylinder press-fitting device 202, it is not necessary to insert the above-mentioned temporary positioning rod 2026. The cylinder cover can be fixed to the cylinder body by just pressing it.

[0244] The fourth pressure head 2023 is a cylindrical structure with an opening at the bottom, and a plurality of through holes (such as oblong holes) can be provided on its side wall to facilitate observation of the internal conditions and to reduce weight. When the fourth pressure head 2023 moves downward to press down the parking cylinder cover 042, the alignment column 2025 is accommodated in the fourth pressure head 2023.

[0245] The alignment column 2025 is mainly used to ensure the alignment of the parking cylinder body 041 and the parking cylinder cover 042. Its structure can be determined according to needs. For example, in this embodiment, refer to Fig.19 The alignment column 2025 includes a first handle 20251, a main column 20252 and a second guide column 20253 connected in sequence from top to bottom. At least the bottom diameter of the main column 20252 matches the central hole diameter of the parking cylinder cover 042. The diameters of the second guide column 20253 and the first handle 20251 are both smaller than the diameter of the main column 20252, and the diameter of the second guide column 20253 matches the inner hole diameter of the parking piston. The second guide column 20253 mainly plays a guiding role. The upper part of the main column 20252 can be adjusted according to the following steps: Fig.19 Shown in FIG. 1 is a conical surface whose diameter tapers upward.

[0246] The positioning plate 2022 is made rotatable, mainly for conveniently rotating the parking cylinder 04 when installing the temporary positioning rod 2026. Generally, the positioning plate 2022 is connected to the third support frame 2021 through a bearing, and the positioning plate 2022 is manually rotated.

[0247] The third driving device 2024 can be, for example, a cylinder, the piston rod of which is vertically arranged and the bottom end of which is fixedly connected to the fourth pressing head 2023, so as to drive the fourth pressing head 2023 to move up and down. A third switch is also arranged on the third support frame 2021, and the third switch is used to control the action of the cylinder. The third switch can be, for example, a hand valve, and the operator can manually operate the hand valve to control the cylinder to move up or down.

[0248] The parking cylinder press-fitting device 202 is used to press-fit the parking spring into the parking cylinder cover 042. Taking the press-fitting of the first type of parking cylinder as an example, the press-fitting process is specifically as follows:

[0249] The parking cylinder body 041 is placed on the positioning plate 2022, so that the multiple second positioning columns 20221 on the positioning plate 2022 are respectively inserted into the multiple mounting holes of the parking cylinder body 041, so as to realize the centering positioning of the parking cylinder body 041. Then the parking piston is placed in the parking cylinder body 041, the parking spring is placed on the parking piston, and the parking cylinder cover 042 is covered; the alignment column 2025 is inserted into the center hole of the parking cylinder cover 042 and the inner hole of the parking piston, so as to realize the vertical alignment of the parking cylinder body 041 and the parking cylinder cover 042.

[0250] Next, a plurality of temporary positioning rods 2026 are inserted into the corresponding mounting holes of the parking cylinder body 041 and the parking cylinder cover 042. After installing one temporary positioning rod 2026, the positioning plate 2022 is manually rotated, and then the next temporary positioning rod 2026 is installed, so that the vertical alignment of the parking cylinder body 041 and the parking cylinder cover 042 is effectively guaranteed. The fourth pressing head 2023 is driven downward by the third driving device 2024 to press the upper end surface of the parking cylinder cover 042 downward to press the parking cylinder cover 042 and the parking cylinder body 041 tightly. After pressing, bolts are inserted into the corresponding mounting holes. After the four bolts are installed (the bolts are manually pre-installed and then torqued using an electric torque wrench), the parking cylinder body 041 and the parking cylinder cover 042 can be fastened together, and then each temporary positioning rod 2026 can be removed to complete the pressing of the parking spring into the parking cylinder cover 042.

[0251] The wedge-shaped body installation device 203 is used to install the wedge-shaped body 05 on the parking cylinder 04. Fig. 20 and Fig.21The wedge-shaped body installation device 203 includes a mounting frame 2031, a first limiting plate 2032, a power column 2033 and a second limiting plate 2034; the first limiting plate 2032 is installed on the mounting frame 2031, and the first limiting plate 2032 is parallel to the bottom surface of the mounting frame 2031 and forms a accommodating limiting space for placing the parking cylinder 04 between the first limiting plate 2032 and the bottom surface of the mounting frame 2031; a limiting groove 20321 is provided on the first limiting plate 2032, which is used to accommodate the parking screw sleeve 043 that is limitedly penetrated in the parking cylinder 04; the power column 2033 can be placed between the U-shaped body of the wedge-shaped body 05 of the brake cylinder, and is circumferentially fixed to the wedge-shaped body 05 through the second limiting plate 2034; a torque wrench insertion hole 20331 (for example, a square hole) is provided on the power column 2033.

[0252] In order to facilitate the limiting of the parking cylinder 04, the mounting frame 2031 includes a bottom plate 20311, an end plate 20312 and two side plates 20313 arranged on the top surface of the bottom plate 20311, the first limiting plate 2032 is connected to the end plate 20312, and the first limiting plate 2032 and the end plate 20312, the bottom plate 20311 and the two side plates 20313 enclose a limiting space.

[0253] In order to facilitate the second limiting plate 2034 to circumferentially fix the wedge-shaped body 05, the power column 2033 passes through the center of the second limiting plate 2034 and is connected (fixed) to the second limiting plate 2034. The second limiting plate 2034 is provided with a first slot 20341 at both ends. The two first slots 20341 of the second limiting plate 2034 can be respectively inserted into the two pull rods 051 of the U-shaped body.

[0254] Among them, the structure of the wedge-shaped body 05 is the existing technology. The wedge-shaped body 05 includes a U-shaped body. The U-shaped body is composed of two pull rods 051 and a connecting rod. The sides of the two pull rods 051 have wedge-shaped surfaces. A screw is connected to the bottom of the U-shaped body. The wedge-shaped body 05 and the screw constitute a wedge-shaped body. When the brake cylinder is working, the wedge-shaped surface of the wedge-shaped body 05 cooperates with the common cylinder to transmit the parking force. The parking screw sleeve 043 is a tubular structure with openings at both ends. Its upper part is a cylindrical structure and the inner wall has an internal thread. Its lower outer wall is a conical surface, and the diameter of the conical surface gradually increases from top to bottom. After the parking screw sleeve 043 is inserted into the parking cylinder 04, the screw is inserted into the parking screw sleeve 043 and threadedly connected with it, so that the connection between the two can be achieved.

[0255] The two side plates 20313 of the mounting frame 2031 are parallel to each other and perpendicular to the end plate 20312. The bottom plate 20311, the end plate 20312, the two side plates 20313, the first limiting plate 2032 and the second limiting plate 2034 of the mounting frame 2031 can all be rectangular plates, the distance between the two side plates 20313 matches the width of the parking cylinder 04, the distance between the first limiting plate 2032 and the bottom plate 20311 should be greater than the height of the parking cylinder 04, after the parking cylinder 04 is pushed to the accommodation limiting space, the parking cylinder 04 is against the end plate 20312, and there is a small gap between the two side plates 20313 and the two sides of the parking cylinder 04 to limit the parking cylinder 04.

[0256] One end of the first limiting plate 2032 is vertically fixed to the end plate 20312, and the other end thereof is provided with a limiting slot 20321 to accommodate and limit the parking screw sleeve 043. The axis of the power column 2033 is perpendicular to the plate surface of the second limiting plate 2034, and the two form a cross structure; the second limiting plate 2034 is provided with first slots 20341 at both ends to form an H-shape as a whole, which can also be regarded as an I-shape.

[0257] In the prior art, when the wedge-shaped body assembly is installed in the parking cylinder 04, the wedge-shaped body 05 is rotated manually; however, since the wedge-shaped body 05 is heavy, it is not easy to operate during installation.

[0258] In this embodiment, the wedge-shaped body assembly is installed on the parking cylinder 04 using the wedge-shaped body installation device 203. The installation process is specifically as follows:

[0259] The parking screw sleeve 043 is inserted from bottom to top into the parking cylinder 04 installed by the parking cylinder press-fitting device 202, specifically, the parking screw sleeve 043 passes through the center hole of the parking cylinder body 041 and the center hole of the parking cylinder cover 042 from bottom to top, and passes out of the parking cylinder cover 042 upwards; since the lower part of the parking screw sleeve 043 is a conical surface, the lower outer diameter of the conical surface is larger than the aperture of the parking cylinder body 041, after the parking screw sleeve 043 is inserted into the parking cylinder 04, the parking screw sleeve 043 is fixedly connected to the parking cylinder 04. Then, the parking cylinder 04 with the parking screw sleeve 043 installed is pushed into the accommodating limit space according to the orientation of the cylinder body at the bottom and the cylinder cover at the top, so as to limit the parking cylinder 04, and at this time, the parking screw sleeve 043 is inserted into the limit groove 20321 of the first limit plate 2032.

[0260] The wedge 05 is placed on the first limit plate 2032, and the screw is inserted into the parking screw sleeve 043. The power column 2033 is placed between the two pull rods 051 of the wedge 05, and the two first slots 20341 at both ends of the second limit plate 2034 are inserted into the two pull rods 051 of the wedge 05 to achieve circumferential fixation of the wedge 05. Next, a torque wrench is inserted into the torque wrench insertion hole 20331 of the power column 2033, and the torque is applied by the torque wrench to drive the wedge 05 to rotate, so that the screw and the parking screw sleeve 043 can be threadedly tightened, and the wedge assembly can be quickly installed in the parking cylinder 04. Compared with the existing manual screwing of the wedge 05 installation, the installation method of this embodiment is more efficient and saves time and effort.

[0261] Reference Fig. 22 The above-mentioned parking piston assembly equipment 300 includes a K-ring detection device 301 and a second rotary oil injection device 302, which are specifically as follows:

[0262] The K-ring detection device 301 is used to detect whether the assembly direction of the K-ring 0451 is correct. Figure 23 to Figure 25 The K-ring detection device 301 includes a detection frame 3011, on which a camera 3012 and a tooling seat are provided. The tooling seat is used to place the second type parking piston 045 of the second type parking cylinder. The camera 3012 can take a picture of the second type parking piston 045 assembled with the K-ring 0451. The control system of the clamp unit brake cylinder assembly production line can compare and analyze the photographic information of the camera 3012 with the pre-stored correct picture information.

[0263] The above-mentioned K-ring 0451 is a conical structure, which is used to be installed on the second type parking piston 045 of the second type parking cylinder, and can ensure the sealing performance of the second type parking piston 045 when moving. During assembly, the K-ring 0451 is first manually installed in the corresponding slot of the second type parking piston 045, and then the second type parking piston 045 with the K-ring 0451 installed is placed in the cylinder body, and then the cylinder cover is fastened and installed. However, when the K-ring 0451 is installed, there are often two situations in the direction of the inclined surface 04511 of the K-ring 0451: the large end of the conical surface of the K-ring 0451 is facing upward, or the small end of the conical surface is facing upward; wherein the large end of the conical surface facing upward is the correct installation direction. In the prior art, due to careless operation by personnel, there is often a situation where the installation direction of the K-ring 0451 is incorrect. The K-shaped detection device in this embodiment can detect the installation direction of the K-ring 0451 (by taking pictures with the camera 3012 for comparison detection) so as to correct its installation orientation in time.

[0264] In order to make the picture information taken by the camera 3012 more clearly identify the K-shaped ring 0451, the detection frame 3011 includes a detection support plate 30111 and a back plate 30112. The camera 3012 and the back plate 30112 are arranged on the detection support plate 30111 and are arranged opposite to each other. The board surface of the back plate 30112 is perpendicular to the board surface of the detection support plate 30111, and the camera 3012 can be installed on the detection support plate 30111 through a bracket; since the K-shaped ring 0451 is a black rubber part, the back plate 30112 is preferably a white plate, which can make the K-shaped ring 0451 more clearly photographed. If necessary, a fill light can also be set on one side of the camera 3012 to make the photo clearer.

[0265] In order to save space, the tooling seat includes a lifting plate 3013 and an annular limit seat 3014 arranged on the lifting plate 3013. The lifting plate 3013 can be lifted up and down and is arranged between the camera 3012 and the back plate 30112. The second type parking piston 045 can be placed on the lifting plate 3013 and limited in the annular limit seat 3014.

[0266] Reference Fig.23 The annular limiting seat may include a limiting ring 30141, which is fixedly connected to the lifting plate 3013 through a plurality of support columns 30142 at the bottom. The limiting ring 30141 may have a notch 101412, and the inner diameter of the limiting ring 30141 matches the outer diameter of the second type parking piston 045 to limit the second type parking piston 045. The K-shaped detection device also includes a lifting drive device 3015, which is connected to the lifting plate 3013 to drive the lifting plate 3013 to rise and fall. In order to guide the movement of the lifting plate 3013, a plurality of third guide columns 30113 are also provided on the detection support plate 30111, and the bottom ends of the third guide columns 30113 are vertically fixed on the detection support plate 30111, and the lifting plate 3013 can be slid up and down and sleeved on each third guide column 30113. The lifting drive device 3015 here can be, for example, a cylinder, the cylinder body of which is fixed to the bottom of the detection support plate 30111 , and the piston rod of the cylinder passes through the detection support plate 30111 and is fixedly connected to the lifting plate 3013 .

[0267] The entire parking piston assembly equipment 300 has a work surface. During installation, the detection support plate 30111 can be installed below the work surface, and the camera 3012 is also located below the work surface. In the initial state, the lifting plate 3013 is located above the work surface; after the second type parking piston 045 equipped with a K-ring 0451 is placed in the annular limit seat 3014, the lifting plate 3013 is driven to move downward, which can better save space on the work surface.

[0268] The K-shaped detection device is used to automatically detect the installation direction of the K-shaped ring 0451. The detection process is as follows:

[0269] Place the second type parking piston 045 assembled with the K-ring 0451 in the annular limit seat 3014, manually press the switch on the cylinder, the cylinder descends, and drives the second type parking piston 045 to move down to the conical position of the camera 3012 just corresponding to the K-ring 0451. The camera 3012 takes a picture of this position, and the control system of the workstation integrated machine collects the photo information of the camera 3012 and compares and analyzes it with the pre-stored correct picture information to determine whether the installation direction of the K-ring 0451 is correct.

[0270] Generally, when the installation direction is correct, the integrated workstation will display correct; when the installation direction is wrong, the integrated workstation will display error and sound and light alarms.

[0271] The second rotary oil spraying device 302 is used for spraying oil to the K-ring 0451 on the second type parking piston 045 of the second type parking cylinder. The structure of the second rotary oil spraying device 302 is the same as that of the first rotary oil spraying device 102, and the specific oil spraying operation is also the same as the oil spraying process of the first rotary oil spraying device 102, which will not be repeated here.

[0272] Reference Fig.26 The above-mentioned hand relief assembly device 400 includes a parking piston press-fit device 401 and a hand relief body press-fit device 402, which are specifically as follows:

[0273] The parking piston press-fitting device 401 is used to press-fit the leather cup onto the first type parking piston 044 of the first type parking cylinder, referring to Fig. 27 and Fig.28 The parking piston press-fitting device 401 includes a parking piston press-fitting assembly and a parking piston positioning frame 4011. The structure of the parking piston press-fitting assembly is the same as that of the main piston press-fitting assembly; the first pressure head 1012 of the parking piston press-fitting assembly and the parking piston positioning frame 4011 are spaced apart from each other and are coaxially arranged on the first support frame 1011 of the parking piston press-fitting assembly. The parking piston positioning frame 4011 is used to center and position the first type of parking piston 044 of the first type of parking cylinder, and the bottom surface of the first pressure head 1012 is used to adsorb the second leather cup of the brake cylinder.

[0274] In order to facilitate the centering positioning of the parking piston positioning frame 4011 on the first type parking piston 044, the parking piston positioning frame 4011 includes a second upper plate body 40111 and a second lower plate body 40112 arranged at an interval up and down, and a plurality of second connecting columns 40113 connected between the second upper plate body 40111 and the second lower plate body 40112; the second upper plate body 40111 has a second center hole at the center, and a third positioning column 40114 is provided on the second lower plate body 40112, the third positioning column 40114 can pass through the second center hole, and the first type parking piston 044 can be inserted into the second center hole and sleeved on the third positioning column 40114.

[0275] The first type parking piston 044 of the first type parking cylinder is an existing structure, which is similar to the structure of the above-mentioned main piston 011, except that the parking piston is not connected to the piston cylinder, and the bowl-shaped bottom of the first type parking piston 044 is not closed. Specifically, the first type parking piston 044 is bowl-shaped, and has an integrally connected parking inner sleeve inside, and the bowl-shaped bottom of the first type parking piston 044 has a central through hole. The structure of the second leather cup is the same as that of the above-mentioned first leather cup. Since the parking inner sleeve in the first type parking piston 044 is relatively short, the structure of the parking piston positioning frame 4011 is different from the structure of the above-mentioned main piston positioning frame 1014.

[0276] Generally, two notches 401111 are provided on both sides of the second upper plate 40111 to facilitate the operator to take out the parking piston.

[0277] When the second leather cup is pressed onto the first type parking piston 044, the parking inner sleeve of the first type parking piston 044 is inserted into the second center hole and sleeved on the third positioning column 40114 to achieve centering positioning. At this time, the bowl edge of the first type parking piston 044 is against the top surface of the second upper plate 40111. After that, the process of pressing the second leather cup using the parking piston press assembly is the same as the process of pressing the first leather cup using the above-mentioned main piston press assembly, which will not be repeated here. After the second leather cup is pressed onto the first type parking piston 044, the oil injection hole on the first pressure head 1012 can be used to spray oil on the second leather cup to improve lubricity.

[0278] Afterwards, the first pressing head 1012 in the parking piston press-fitting assembly can be replaced with a flat pressing head, and the parking piston sleeve is passed through the central through hole of the bottom of the first type parking piston 044 and aligned with the inner hole of the parking inner sleeve, and the first driving device 1013 of the parking piston press-fitting assembly is used to drive the flat pressing head downward, so that the parking piston sleeve can be press-fitted into the inner hole of the first type parking piston 044. Since the parking piston has a relatively high hardness, the parking piston sleeve and the parking inner sleeve are interference fit, and it is more time-saving and labor-saving to press-fit using a press machine.

[0279] The manual release body press-fit device 402 is used to press the elastic cylindrical pin into the installation hole of the manual release body, referring to Figure 29 to Figure 32 The hand relief body pressing device 402 includes a fourth support frame 4021, a limit box body 4022, a fifth pressure head 4023 and a fourth driving device 4024; the fifth pressure head 4023 and the limit box body 4022 are arranged on the fourth support frame 4021 at an interval up and down, and the limit box body 4022 includes a seat body 40221 and a cover body 40222 that can be buckled on the seat body 40221. The top surface of the seat body 40221 is provided with a second slot 402211 for inserting and releasing the hand relief body 06; the cover body 40222 is provided with a guide hole, and the cover body 40 A guide sleeve is provided on the bottom surface of 222, and the guide sleeve can be directly opposite to the guide hole (the guide sleeve can be connected to the guide hole); the guide sleeve can be inserted into the installation groove 061 of the hand relief body 06 after the cover body 40222 is covered on the seat body 40221, and the first pressure rod 40223 can be inserted in the guide hole; the fourth driving device 4024 is connected to the fifth pressure head 4023, and after placing the elastic cylindrical pin of the hand relief body 06 and the first pressure rod 40223 in the guide hole in sequence, the first pressure rod 40223 can be driven to press the elastic cylindrical pin into the installation hole of the hand relief body 06.

[0280] The hand release body 06 is mainly used for manually releasing the brake cylinder. Its structure is the existing structure. It is roughly a square block with a mounting groove 061 on the top surface. Two mounting holes are provided at the bottom of the mounting groove 061 for mounting two elastic cylindrical pins. The elastic cylindrical pins are very small, and the mounting holes on the hand release body 06 are also very small. In the prior art, the elastic cylindrical pins are installed by manually aligning the mounting holes. It is difficult to hold the elastic cylindrical pins and install them, which is inefficient.

[0281] In this embodiment, the hand relief body press-fitting device 402 is used to press-fit the elastic cylindrical pin into the mounting hole of the hand relief body 06, and the press-fitting process is as follows:

[0282] Open the cover 40222, insert the hand relief body 06 into the second slot 402211 of the seat 40221; cover the cover 40222, and then insert the guide sleeve into the installation slot 061 of the hand relief body 06 (generally, the bottom surface of the guide sleeve just abuts against the bottom of the installation slot 061 of the hand relief body 06), and face the installation hole on the hand relief body 06. Then put the elastic cylindrical pin into the guide hole, and then put the first pressure rod 40223 into the guide hole, the top of the first pressure rod 40223 is located outside the cover 40222 and the lower end of the first pressure rod 40223 abuts against the top surface of the elastic cylindrical pin. Use the fourth driving device 4024 to drive the fifth pressure head 4023 to press the first pressure rod 40223 downward, so that the first pressure rod 40223 presses the elastic cylindrical pin downward, and the elastic cylindrical pin can be pressed into the installation hole of the hand relief body 06. Compared with the existing manual alignment installation, the press-fitting method of this embodiment can effectively ensure that the elastic cylindrical pin is aligned with the installation hole, and the installation efficiency is higher.

[0283] The diameter of the elastic cylindrical pin is slightly larger than the mounting hole diameter of the hand relief body 06. After the elastic cylindrical pin and the first pressing rod 40223 are inserted into the guide hole, only the elastic cylindrical pin is stressed during the entire press-fitting process, which can avoid the hand relief body 06 from being deformed by pressure.

[0284] Generally, a guide block 40224 is fixed on the top surface of the cover body 40222, and a through hole is provided on the guide block 40224, which is arranged to penetrate upward and downward, and the through hole is arranged opposite to the guide hole on the cover body 40222 (the through hole is connected to the guide hole), and the elastic cylindrical pin of the hand release body 06 and the first pressure rod 40223 can be inserted through the through hole in sequence. The number of the through holes is the same as the number of the guide holes and the guide sleeves, and they all play a guiding role to ensure that the elastic cylindrical pin can be aligned when installed.

[0285] Alternatively, an open groove may be provided on the top surface of the cover body 40222, and a through hole may be provided at the bottom of the open groove, and the guide block 40224 may be inserted and limited in the open groove, and each through hole on the guide block 40224 is connected to the through hole, and a part of the through hole constitutes a guide hole of the cover body 40222. Only one through hole is provided, and the number of through holes is the same as the number of guide sleeves, and the part of the through hole located below the top surface of the cover body 40222 constitutes a corresponding guide hole, and the through hole also mainly plays a guiding role, so as to utilize the guide block 40224 to play a guiding role.

[0286] It is understood that the size of the second slot 402211 of the seat 40221 should match the size of the hand relief body 06, and a small gap should be left between the two after the hand relief body 06 is inserted into the second slot 402211. However, since the elastic cylindrical pin is very small and the mounting hole on the hand relief body 06 is also very small, the small gap between the hand relief body 06 and the second slot 402211 may also affect the alignment during installation.

[0287] In order to improve the accuracy of alignment, a movable limit adjustment rod 4025 is inserted into one side of the seat body 40221, and the limit adjustment rod 4025 can extend into the second slot 402211 and can abut against the side wall of the hand relief body 06.

[0288] During the press-fitting process, after the hand relief body 06 is inserted into the second slot 402211 of the seat body 40221, the limit adjustment rod 4025 is adjusted to move so that it rests against the side of the hand relief body 06, so that the two sides of the hand relief body 06 are limited by the side walls of the second slot 402211 and the limit adjustment rod 4025, effectively preventing the hand relief body 06 from being pressed off during the process of the first pressure rod 40223 pressing down the elastic cylindrical pin, thereby further improving the accuracy of the press-fitting.

[0289] The structure of the limit adjustment rod 4025 can be realized as follows: Figure 30 to Figure 32 A side hole connected to the second slot 402211 is opened on the side wall of the seat body 40221, and the limit adjustment rod 4025 can be slidably inserted in the side hole; a first step 402214 is provided on the side wall of the seat body 40221 at a position corresponding to the side hole, and a second step 40251 is provided on the limit adjustment rod 4025 near its first end, and an adjustment spring is sleeved on the limit adjustment rod 4025, and the two ends of the adjustment spring respectively press against the first step 402214 and the second step 40251. A second handle 40252 is connected to the second end of the limit adjustment rod 4025, and two positioning blocks 402212 are provided on the side wall of the seat body 40221, located on both sides of the side hole. The second handle 40252 can abut against the positioning blocks 402212 to retract the first end of the limit adjustment rod 4025 into the side hole, or the second handle 40252 can be inserted into the interval area between the positioning blocks 402212 by rotation to move the limit adjustment rod 4025 inwardly and then abut against the side wall of the hand relief body 06.

[0290] In this embodiment, a baffle plate 402213 is fixedly provided on the side wall of the seat body 40221. A limiting hole corresponding to the side hole is opened on the baffle plate 402213. The aperture of the limiting hole is smaller than the aperture of the side hole. The portion of the baffle plate 402213 between the limiting hole and the side hole constitutes the first step 402214. Two positioning blocks 402212 are fixed on the baffle plate 402213. The second handle 40252 is a flat structure, the thickness of which is smaller than the interval between the two positioning blocks 402212, and the width of which is larger than the interval between the two positioning blocks 402212. When the second handle 40252 is placed horizontally, it abuts against the two positioning blocks 402212. At this time, the adjustment spring is in a compressed state, and the limit adjustment rod 4025 is retracted. After inserting the hand relief body 06 into the second slot 402211 on the seat body 40221, manually rotate the second handle 40252 90° and then release it. The second handle 40252 can be placed vertically and inserted into the interval area between the two positioning blocks 402212. Under the action of the adjustment spring, the limit adjustment rod 4025 will automatically move inward and extend out of the side hole, and press against the hand relief body 06 to ensure that the position of the hand relief body 06 is fixed.

[0291] One side of the cover body 40222 is hinged to one side of the base body 40221, and the cover body 40222 can be opened in a flip-up manner, which is easy to operate.

[0292] Reference Fig.33 The above-mentioned connecting rod assembly device 500 includes a disc spring push device 501, a connecting rod bushing press-fit device 502 and a connecting rod elastic pin press-fit device 503, which are specifically as follows:

[0293] The disc spring pushing device 501 is used for automatic discharging and oil injection of the disc spring 07, that is, the disc spring 07 is automatically pushed out piece by piece and oil is injected into the disc spring 07. Figure 34 to Figure 39 The disc spring push device 501 includes a support seat 5011 and at least one set of disc spring push components arranged on the support seat 5011, and the disc spring push components include a fifth drive device 5012, a push plate 5013, a disc spring placement groove 5015, a disc spring injection chamber 5016 and a disc spring taking groove 5017 which are sequentially arranged on the support seat 5011 along the horizontal moving direction (the horizontal moving direction is also the axial direction of the driving shaft of the fifth drive device 5012); the disc spring placement groove 5015 is used to place multiple disc springs 07 in stacks. The fifth driving device 5012 is connected to the push plate 5013, and can drive the push plate 5013 to push the disc spring 07 located at the bottom layer in the disc spring placement groove 5015 into the disc spring spray chamber 5016. The disc spring 07 located at the bottom layer in the disc spring placement groove 5015 can push the disc spring 07 located in the disc spring spray chamber 5016 into the disc spring taking groove 5017 when moving into the disc spring spray chamber 5016.

[0294] Specifically, an anti-deflection block 5014 is provided on the support seat 5011 and between the disc spring placement groove 5015 and the push plate 5013, and an anti-deflection channel is formed between the anti-deflection block 5014 and the support seat 5011; the shape of the push plate 5013 and the shape of the anti-deflection channel both match the shape of the disc spring 07, and the push plate 5013 can be movably inserted in the anti-deflection channel.

[0295] The setting of the anti-deviation channel can guide the push plate 5013 during its movement, prevent the push plate 5013 from deflecting, ensure that the push plate 5013 is always in a horizontal state, and ensure that the push plate 5013 only pushes one disc spring 07 forward each time.

[0296] The end of the push plate 5013 away from the fifth driving device 5012 has a notch 50131, and the shape of the notch 50131 matches the edge profile of the disc spring 07. After the push plate 5013 is extended, the notch 50131 at the end thereof can be pressed against the edge of the disc spring 07 to more stably push out the disc spring 07. The shape of the push plate 5013 matches the shape of the corresponding single disc spring 07, and the thickness of the push plate 5013 is the same as the thickness of the corresponding disc spring 07. It is a contoured push plate, and the cross-sectional shape of the anti-deflection channel is the same as the cross-sectional shape of the push plate 5013.

[0297] The number of groups of the push disc spring assembly is determined according to the number of types of disc springs 07 required. For example, in this embodiment, two types of disc springs 07 are mainly used, one is a flat disc spring 07 (such as Fig.36 As shown), the corresponding push plate 5013 is a rectangular flat plate structure (as shown Fig.38 As shown), the anti-deflection channel is a rectangular flat channel; the other is a saddle-shaped disc spring 07 (as shown Fig.37 As shown), the corresponding push plate 5013 is an arc-shaped plate (as shown Fig.39 As shown), the anti-deflection channel is also a corresponding arc-shaped channel.

[0298] In order to facilitate the placement of more disc springs 07, a plurality of columns 50151 surrounding the disc spring placement groove 5015 are provided on the support seat 5011, and a pressure block 50152 that can move up and down is provided between the plurality of columns 50151. The pressure block 50152 can be pressed against the disc spring 07 located on the current top layer in the disc spring placement groove 5015 under the action of gravity.

[0299] The number of columns 50151 is determined according to the needs. For example, in this embodiment, there are four columns 50151. After stacking a plurality of disc springs 07 in a stack in the disc spring placement slot 5015, the moving pressing block 50152 is pressed against the disc spring 07 at the current top layer to limit the position. When the disc springs 07 are continuously pushed out from the bottom layer, the number of the stacked disc springs 07 decreases, the overall height decreases, and the pressing block 50152 automatically descends under the action of gravity to press against the disc spring 07 at the current top layer.

[0300] The above-mentioned disc spring oil spray chamber 5016 has an inlet and an outlet 50161 arranged opposite to each other, and the shapes of the inlet and the outlet 50161 match the shape of the disc spring 07, and specifically, the shapes of the inlet and the outlet 50161 are the same as the cross-sectional shape of the push plate 5013. The disc spring 07 can be pushed into the disc spring oil spray chamber 5016 through the inlet, and then pushed out through the outlet 50161 after oil is sprayed. Generally, a pipe joint is connected to the top of the disc spring oil spray chamber 5016, and the pipe joint is connected to an oil pipe, so that oil can be automatically injected into the disc spring oil spray chamber 5016.

[0301] The disc spring taking groove 5017 is composed of a groove-shaped box body with an opening at the top, and the outlet 50161 of the disc spring oil spraying chamber 5016 is connected to a groove wall on one side of the disc spring taking groove 5017. When the push plate 5013 pushes the disc spring 07 into the disc spring oil spraying chamber 5016, the previous disc spring 07 can be pushed out into the disc spring taking groove 5017. In order to facilitate the operator to take out the oil-sprayed disc spring 07, a bottom hole 50171 is opened at the bottom of the disc spring taking groove 5017 for easy taking.

[0302] To facilitate processing and installation, the support seat 5011 includes a support base plate 50111 and a driving support frame 50112 and a disc spring support frame 50113 fixed on the support base plate 50111; a movable groove 501131 extending along the above-mentioned horizontal moving direction and penetrating the first end face and the second end face of the disc spring support frame 50113 is provided on the top surface of the disc spring support frame 50113; the anti-deflection block 5014 is arranged on the movable groove 501131 and close to the first end face of the disc spring support frame 50113, and is enclosed with the bottom of the movable groove 501131 to form the above-mentioned anti-deflection channel.

[0303] An oil spray cover 50162 is provided on the movable groove 501131 and near the second end surface of the disc spring support frame 50113. The oil spray cover 50162 and the movable groove 501131 enclose the above-mentioned disc spring oil spray chamber 5016, and the bottom two side surfaces of the oil spray cover 50162 and the groove bottom of the movable groove 501131 enclose the above-mentioned inlet and outlet 50161. The pipe joint is installed on the top surface of the oil spray cover 50162. The part of the movable groove 501131 located between the anti-deflection block 5014 and the oil spray cover 50162 constitutes the above-mentioned disc spring placement groove 5015, and a plurality of columns 50151 are fixed on the disc spring support frame 50113 on both sides of the movable groove 501131. The fifth driving device 5012 can be, for example, a cylinder, whose cylinder body is fixed on the driving support frame 50112, and the end of its piston rod is fixedly connected to the end of the push plate 5013, and the other end of the push plate 5013 can be moved into the anti-deviation channel.

[0304] In the prior art, the placement and oil spraying of the disc spring 07 are all done manually by the operator, but in this embodiment, it can be done automatically, and one disc spring 07 can be pushed out each time and the disc spring 07 can be automatically sprayed with oil, which saves labor costs and is more efficient. The specific working process of the disc spring pushing device 501 is as follows:

[0305] The stack of disc springs 07 is stacked in the disc spring placement slot 5015, and the pressing block 50152 is moved to press the disc springs 07. The fifth driving device 5012 works, driving the push plate 5013 to move forward along the anti-deflection channel, and pushing the disc spring 07 located at the bottom layer in the disc spring placement slot 5015 forward, pushing it into the disc spring oil injection chamber 5016 from the inlet of the disc spring oil injection chamber 5016, and automatically spraying oil on the disc spring 07 using the oil pipe connected to the pipe joint; then the push plate 5013 continues to push the next disc spring 07, pushing the disc spring 07 currently located at the bottom layer in the disc spring placement slot 5015 forward, and when the disc spring 07 is pushed into the disc spring oil injection chamber 5016, it can push the previous disc spring 07 originally located in the disc spring oil injection chamber 5016 into the disc spring taking slot 5017, and the operator takes the oil-sprayed disc spring 07 from the disc spring taking slot 5017 to proceed to the next process.

[0306] The push plate 5013 is designed to match the single disc spring 07, so that the single disc spring 07 can be automatically pushed out. The pushed disc spring 07 enters the disc spring oil injection chamber 5016, and the previous disc spring 07 can be pushed out when the next disc spring 07 is pushed out. By setting the corresponding degree, the disc spring 07 can be automatically pushed out according to the set number, and a fixed number of disc springs 07 can be pushed out, avoiding the error in the number of disc springs 07, and playing a mistake-proofing function; the disc spring 07 can be automatically oiled while being pushed out, which improves the assembly efficiency.

[0307] The connecting rod bushing press-fitting device 502 is used to press-fit the bushings on both sides of the connecting rod 081 in sequence and pre-compress the disc spring 07. Figure 40 to Figure 42 The connecting rod bushing press-fitting device 502 includes a fifth support frame 5021, a rotating frame 5022, a sixth pressing head 50241, a seventh pressing head 50242, an eighth pressing head 50243, a first positioning member 50251, a second positioning member 50252, a lead screw positioning member 5026 and a sixth driving device 5027; the rotating frame 5022 is rotatably arranged on the fifth support frame 5021, and the rotating frame 5022 includes an upper rotating disk 50221 and a lower rotating disk 50222 which are spaced apart from each other (the upper rotating disk 50221 and the lower rotating disk 50222 are fixedly connected by a center column 50223), Three groups of elastic movable rods 5023 that can move up and down are circumferentially arranged at intervals on the upper turntable 50221, and the sixth pressure head 50241, the seventh pressure head 50242 and the eighth pressure head 50243 are respectively connected to the bottom ends of the three groups of elastic movable rods 5023; the driving end 50271 of the sixth driving device 5027 is arranged above the elastic movable rod 5023 and is eccentrically arranged with the rotating frame 5022, and the driving end 50271 of the sixth driving device 5027 can abut against the elastic movable rod 5023 rotated to the bottom of the driving end 50271 and drive the elastic movable rod 5023 to move downward.

[0308] The first positioning member 50251, the second positioning member 50252 and the screw positioning member 5026 are arranged coaxially with the sixth pressure head 50241, the seventh pressure head 50242 and the eighth pressure head 50243 respectively. The first positioning member 50251 is used to locate the first end of the connecting rod 081 for installing the brake cylinder, the second positioning member 50252 is used to locate the second end of the connecting rod 081 for installing the brake cylinder, and the screw positioning member 5026 is used to locate the screw 083 for installing the brake cylinder.

[0309] The connecting rod 081 in the brake cylinder is mainly used to connect with the screw 083 to transmit the braking force. The structure of the connecting rod 081 is the existing structure, and its left and right sides are symmetrical. The inner holes on the left and right sides are respectively used to install two yellow sleeves, which are also called bushings. They are wear-resistant bushings that can protect the connecting rod 081. The structure of the bushing is also the existing structure, which is a cylindrical structure with openings at both ends, and the outer wall of one end has a convex ring with an increased diameter.

[0310] The connecting rod bushing press-fitting device 502 has three pressing heads, which can first press-fit one bushing into the inner hole on one side of the connecting rod 081, and then press-fit the other bushing into the inner hole on the other side of the connecting rod 081; after manually placing the disc spring 07 in the annular groove of the connecting rod 081 and covering it with the pressure cover 082, the device can press the pressure cover 082 down to pre-compress the disc spring 07 so as to manually insert a temporary pin; the pressure cover 082 has a hexagonal nut structure (i.e., reset nut 0821), and the side wall of the reset nut 0821 is provided with a socket, and the end side wall of the lead screw 083 is provided with a corresponding socket, and the temporary pin can be inserted into the through hole of the hexagonal nut structure and the socket of the lead screw 083 to fix the pressure cover 082 to the lead screw 083. The connecting rod 081, two bushings, disc spring 07, pressure cover 082 and lead screw 083 after being connected constitute the connecting rod assembly 08. The specific installation process is:

[0311] Install the connecting rod 081 on the first positioning member 50251 with its axis horizontally placed, rotate the rotating frame 5022 until the sixth pressing head 50241 is facing the driving end 50271 of the sixth driving device 5027, and place one of the bushings in the corresponding inner hole of the connecting rod 081; the sixth driving device 5027 can drive the sixth pressing head 50241 to press down the bushing by pressing down the corresponding elastic movable rod 5023, so as to press the bushing into the inner hole on one side of the connecting rod 081.

[0312] Then flip the connecting rod 081 180 degrees and install it on the second positioning piece 50252, rotate the rotating frame 5022 until the seventh pressing head 50242 is facing the driving end 50271 of the sixth driving device 5027, and place the other bushing in the corresponding inner hole of the connecting rod 081; the sixth driving device 5027 can drive the seventh pressing head 50242 to press down the bushing by pressing down the corresponding elastic movable rod 5023, so as to press the bushing into the inner hole on the other side of the connecting rod 081.

[0313] Afterwards, the screw 083 is installed on the screw positioning member 5026, and the rotating frame 5022 is rotated until the eighth pressure head 50243 is facing the driving end 50271 of the sixth driving device 5027, and the connecting rod 081 is placed in a vertical position with the axis, and the disc spring 07 is manually taken out from the disc spring taking groove 5017 of the disc spring pushing device 501 and placed in the annular groove of the connecting rod 081, and the pressure cover 082 is covered, and the connecting rod 081 is sleeved on the screw 083. At this time, the end of the screw 083 passes through the center hole of the connecting rod 081, the inner hole of the disc spring 07 and the inner hole of the pressure cover 082 in turn and passes out; the sixth driving device 5027 can move downward by pressing down the corresponding elastic moving rod 5023, so as to drive the eighth pressure head 50243 to press down the pressure cover 082, so as to realize pre-compression of the disc spring 07. Then, the temporary pins are manually inserted into the gland 082 and the lead screw 083, the holes of the gland 082 and the lead screw 083 for passing the elastic pins are aligned, and the gland 082 and the lead screw 083 are temporarily fixed to complete the temporary assembly of the connecting rod component 08.

[0314] In the prior art, two bushings are respectively pressed into the inner holes on both sides of the connecting rod 081, and the disc spring 07 is compressed, which requires a press machine with three independent stations, which occupies a large space, is costly, and has low press-fitting efficiency. In this embodiment, the three press-fitting stations are integrated into one device, and the three pressing heads are integrated together to form a rotating three-column pressing head. The next pressing head can be replaced by rotating the rotating frame 5022, and the three press-fitting operations are performed in sequence, which has a higher degree of integration, occupies less space, has a more compact station, has a high press-fitting efficiency, and improves work efficiency.

[0315] In order to facilitate the movement and reset of the elastic moving rod 5023, refer to Fig.41 A third return spring 50231 is sleeved on the elastic moving rod 5023 , and two ends of the third return spring 50231 are respectively pressed against between the upper end limit portion 50232 of the elastic moving rod 5023 and the upper turntable 50221 .

[0316] In the initial state, the elastic movable rod 5023 relies on gravity to make the third return spring 50231 in a slightly compressed state. When the fifth driving device 5012 presses down the elastic movable rod 5023, the third return spring 50231 is further compressed. When the driving end 50271 of the fifth driving device 5012 moves up and no longer presses down the elastic movable rod 5023, the elastic movable rod 5023 will move up to the initial position under the action of the third return spring 50231.

[0317] Generally, a third linear bearing 50233 is fixedly provided on the upper turntable 50221, the elastic moving rod 5023 is inserted into the third linear bearing 50233, and the lower end of the third return spring 50231 abuts against the top of the third linear bearing 50233; the third linear bearing 50233 can play a guiding and protective role.

The rotating adjustment cylinder 50261 is rotatably connected to the lower turntable 50222, and the fixed limiting cylinder 50262 is inserted in the rotating adjustment cylinder 50261 and fixedly connected to the lower turntable 50222; a plurality of groups of support grooves 502611 with different heights are provided on the rotating adjustment cylinder 50261, and two long strip-shaped adjustment holes 502621 arranged opposite to each other are provided on the lower side wall of the fixed limiting cylinder 50262. The transverse limiting rod 50263 can be inserted in the two adjustment holes 502621 and supported in the corresponding supporting grooves 502611. The fixed limiting cylinder 50262 is used to place the screw 083, and the bottom of the screw 083 can be supported against the transverse limiting rod 50263.

[0319] The lower turntable 50222 can be connected to the fifth support frame 5021 through a bearing and can be rotated manually. The bottom of the rotation adjustment cylinder 50261 is also connected to the lower turntable 50222 through a bearing and can be rotated manually. The rotation adjustment cylinder 50261 is a cylindrical structure with an open top, and multiple groups of support grooves 502611 are opened on its top. Each group of support grooves 502611 includes two support grooves 502611 symmetrically arranged relative to the center of the rotation adjustment cylinder 50261. The corresponding positions of each group of support grooves 502611 are different in height; by supporting the transverse limit rods 50263 on different support grooves 502611, screws 083 of different lengths can be matched. In the prior art, in order to match screws 083 of different lengths, different positioning members can only be replaced. In this embodiment, multiple groups of support sleeves of different heights are integrated on the rotation adjustment cylinder 50261, and only the position of the transverse limit rod 50263 needs to be adjusted, which is simple and convenient, and has stronger adaptability.

[0320] Generally, a side opening connected to the top of the fixed limiting cylinder 50262 is provided on the upper side wall, so that the lead screw 083 can be placed more conveniently.

[0321] The first positioning member 50251 and the second positioning member 50252 are both fixed on the lower rotating disk 50222, and both have a fourth positioning column 50253. The size of the fourth positioning column 50253 of the first positioning member 50251 should match the diameter of the inner hole on one side of the connecting rod 081, and the size of the fourth positioning column 50253 of the second positioning member 50252 should match the inner diameter of the bushing inserted in the inner hole on one side of the connecting rod 081. The bottom of the fourth positioning column 50253 has an annular first flange 50254, which is used to support the corresponding side end surface of the connecting rod 081 during the pressing process.

[0322] The sixth pressure head 50241 and the seventh pressure head 50242 mentioned above both include a first cylindrical pressure block 50244 and a first cylindrical guide block 50245 connected up and down, and the diameter of the first cylindrical guide block 50245 is smaller than the diameter of the first cylindrical pressure block 50244. The first cylindrical guide block 50245 is used to be inserted into the corresponding side inner hole of the connecting rod 081 or inserted into the inner hole of the installed bushing to play a guiding role; the bottom surface of the first cylindrical pressure block 50244 can be pressed against the end surface of the bushing and press the bushing downward during the downward pressing process. The eighth pressure head 50243 mentioned above can be a flat pressure head, which abuts against the top surface of the reset nut 0821 of the pressure cover 082 when pressing downward. After pressing into place, the temporary pin is inserted into the reset nut 0821 and the lead screw 083 while maintaining the downward pressing state.

[0323] The connecting rod elastic pin press-fit device 503 is used to press-fit the elastic pin to fix the reset nut 0821 and the lead screw 083, that is, to replace the temporary pin with the elastic pin and press-fit the elastic pin into the insertion holes of the reset nut 0821 and the lead screw 083. Figure 43 to Figure 46 The connecting rod elastic pin press-fitting device 503 includes a sixth support frame 5031, a ninth pressure head 5032, a nut support seat 5033, a screw pressing mechanism 5034 and a seventh driving device 5035; the ninth pressure head 5032 and the nut support seat 5033 are arranged on the sixth support frame 5031 with an interval up and down, and the nut support seat 5033 has a U-shaped seat 50331 protruding outward (the U-shaped opening direction of the U-shaped seat 50331 is arranged in the horizontal direction and faces the screw pressure The ninth pressure head 5032 is arranged opposite to the inner hole of the U-shaped seat 50331, and the U-shaped seat 50331 is used to support the reset nut 0821 on the pressure cover 082 connected to the end of the connecting rod 081; the screw clamping mechanism 5034 is arranged on the sixth support frame 5031, and is used to clamp and fix the screw 083 connected to the connecting rod 081; the seventh driving device 5035 is connected to the ninth pressure head 5032 and can drive the ninth pressure head 5032 to move up and down.

[0324] During press-fitting, first place the connecting rod assembly 08 temporarily assembled by the connecting rod bushing press-fitting device 502 in the orientation that the axis of the connecting rod 081 is horizontally placed (that is, the axis of the lead screw 083 is also horizontally placed), so that the reset nut 0821 on the pressure cover 082 is placed on the U-shaped seat 50331, and the temporary pin is placed vertically and facing the inner hole of the U-shaped seat 50331, and the lead screw 083 is clamped by the lead screw clamping mechanism 5034 to fix the connecting rod assembly 08.

[0325] Then, the elastic pin is placed on the temporary pin, and the seventh driving device 5035 is used to drive the ninth pressing head 5032 to press down the elastic pin until the elastic pin replaces the temporary pin, thereby pressing the elastic pin into the holes of the reset nut 0821 and the lead screw 083.

[0326] Compared with the prior art in which a person manually presses an elastic pin to align the hole, the device in this embodiment saves time and effort and has a higher installation efficiency.

[0327] The structure of the screw clamping mechanism 5034 can be determined as needed, as long as it can firmly clamp the screw 083. Fig.44 As shown in the figure, the screw clamping mechanism 5034 includes a support block 50341 with a V-shaped groove on the top surface and a movable clamping block 50342 with a V-shaped groove on the bottom surface. One side of the movable clamping block 50342 is hinged to the support block 50341. The movable clamping block 50342 can be pressed on the screw 083 after the screw 083 is placed in the V-shaped groove of the support block 50341. The screw 083 is clamped and pressed in the channel surrounded by the V-shaped groove of the support block 50341 and the V-shaped groove of the movable clamping block 50342. The movable clamping block 50342 can be connected to a manual clamp to achieve its opening or clamping.

[0328] The ninth pressure head 5032 is preferably detachably connected to the seventh driving device 5035, for example, a quick-release connector can be used to realize the disassembly and assembly of the two. The ninth pressing head 5032 includes a first pressing head 50321 and a second pressing head 50322. The first pressing head 50321 includes a cylindrical first connecting block 503211 and a second pressing rod 503212 fixedly connected up and down. During press-fitting, the lower end of the second pressing rod 503212 faces the elastic cylindrical pin and presses down the elastic cylindrical pin; the second pressing head 50322 includes a rectangular second connecting block and a bending rod 503221 fixedly connected up and down. The bending rod 503221 includes a straight rod and an oblique rod connected up and down. The upper end of the straight rod is fixedly connected to the bottom edge of the second connecting block, and the bottom of the oblique rod has a plane. The axis of the vertical rod 10362 deviates from the axis of the elastic cylindrical pin. During press-fitting, the bottom plane of the oblique rod presses down the elastic cylindrical pin, and the deflection of the bending rod 503221 can be better avoided. During installation, one of the first pressing head 50321 and the second pressing head 50322 is connected to the seventh driving device 5035 , depending on the shape of the connecting rod 081 , so as to avoid interference between the ninth pressing head 5032 and components on the connecting rod 081 .

The cylinder bushing pressing equipment 600 is located in front of the cylinder loading equipment 700, and the cylinder oil injection equipment 800 corresponds to the position between the cylinder loading equipment 700 and the intermediate assembly equipment 900. The five equipments on the upper conveyor line, as well as the cylinder bushing pressing equipment 600 and the cylinder oil injection equipment 800 are all assembly stations, responsible for assembling the parts pre-installed in the pre-installation station into the common cylinder body 09.

The following is an introduction to these assembly stations:

[0331] Reference Fig.47 The cylinder bushing pressing device 600 includes a cylinder bushing pressing device 601, which is used to press the bushings on both sides of the cylinder body 09 of the common cylinder. Fig.48 The cylinder bushing device 601 includes a seventh support frame 6011, a cylinder support 6012, a tenth pressure head 6013, an eleventh pressure head 6014 and an eighth drive device 6015; the tenth pressure head 6013 and the eleventh pressure head 6014 are spaced apart and coaxially arranged on the seventh support frame 6011, the cylinder support 6012 is arranged on the seventh support frame 6011 and is used to support the side wall of the common cylinder body 09, and the eighth drive device 6015 is connected to the tenth pressure head 6013 and can drive the tenth pressure head 6013 to move up and down.

[0332] The structure of the commonly used cylinder body 09 is an existing structure, and two inner holes are symmetrically provided on both sides thereof for installing two yellow sleeves. The yellow sleeve is also the bushing 091, which is a wear-resistant bushing that can protect the commonly used cylinder body 09; the structure of the bushing 091 is also an existing structure, which is a cylindrical structure with openings at both ends, and the outer wall at one end has a convex ring with an increased diameter.

[0333] Reference Fig.48The cylinder support 6012 is arranged close to the eleventh pressure head 6014, and its top surface is a V-shaped groove, which can support the cylindrical outer wall of the common cylinder body 09. The tenth pressure head 6013 includes a second cylindrical pressure block 60131 and a second cylindrical guide block 60132 connected up and down. The diameter of the second cylindrical guide block 60132 is smaller than the diameter of the second cylindrical pressure block 60131. The second cylindrical guide block 60132 is used to be inserted into the inner hole of the bushing 091 placed in the inner hole on one side of the common cylinder body 09 to play a guiding role; during the pressing process, the bottom surface of the second cylindrical pressure block 60131 can be pressed against the end surface of the bushing 091 and press the bushing 091 downward. The eleventh pressure head 6014 includes a third cylindrical guide block 60141, and a second annular flange 60142 is protruding from the bottom of the third cylindrical guide block 60141. The third cylindrical guide block 60141 can be inserted into the inner hole of the bushing 091 placed in the inner hole on the other side of the common cylinder body 09 to play a guiding role; the second flange 60142 is used to support the side of the common cylinder body 09 during the pressing process.

[0334] During operation, two bushings 091 are respectively inserted into the inner holes on both sides of the common cylinder body 09, and then the common cylinder body 09 is installed on the cylinder body support 6012 and the eleventh pressure head 6014 in a state where its axis is placed horizontally. At this time, the side wall of the common cylinder body 09 is supported on the cylinder body support 6012, and the bushing 091 placed in the side hole at the bottom of the common cylinder body 09 is sleeved on the third cylindrical guide block 60141 of the eleventh pressure head 6014; the bushing 091 placed in the side hole at the top of the common cylinder body 09 is opposite to the tenth pressure head 6013. After that, the eighth driving device 6015 is started to drive the tenth pressure head 6013 to move downward, so that the two bushings 091 can be pressed into the inner holes on both sides of the common cylinder body 09 at the same time. Compared with the prior art that needs to use a press to press two bushings 091 separately one by one, the present embodiment can press two bushings 091 at the same time, and the installation efficiency is higher.

[0335] Further, a rotatable cylinder turntable 1301 is provided on the cylinder tray 1300, referring to Figures 49 to 52 Two fixed seats 1302 are symmetrically arranged on the cylinder body turntable 1301, and a movable fixed insertion rod 1303 is arranged in the fixed seat 1302; the fixed insertion rod 1303 can be inserted into the bushing 091 of the common cylinder body 09 after the common cylinder body 09 is placed on the cylinder body turntable 1301.

[0336] The above-mentioned tray can be, for example, a rectangular tray, and the cylinder turntable 1301 can be connected to the tray through a bearing and can be rotated manually. A through hole with a horizontal axis is provided on the fixed seat 1302, and the fixed plug rod 1303 can be movably inserted in the through hole, and the two are clearance-matched. After the two bushings 091 are pressed onto the common cylinder body 09 by using the cylinder body pressing bushing device 601, the common cylinder body 09 is placed on the cylinder turntable 1301, and then the two fixed plug rods 1303 in the two fixed seats 1302 are slid inward, so that the fixed plug rod 1303 is inserted into the inner hole of the corresponding bushing 091 (the two are clearance-matched), so that the positioning and fixation of the common cylinder body 09 can be achieved.

[0337] Reference Fig.53 The cylinder loading device 700 includes a first integrated press 701, referring to Fig.54 The first integrated press machine 701 includes an eighth support frame 7011, a twelfth ram 7012 and a ninth drive device 7013. The twelfth ram 7012 is a cylindrical structure. The ninth drive device 7013 is connected to the twelfth ram 7012 and can drive the twelfth ram 7012 to move up and down.

[0338] The brake cylinder includes a compound brake cylinder and a single-cylinder brake cylinder. The compound brake cylinder includes a common cylinder, an intermediate body and a parking cylinder 04. The intermediate body connects the common cylinder and the parking cylinder 04. The single-cylinder brake cylinder only includes the common cylinder, and does not include the parking cylinder 04 and the intermediate body. The first integrated press 701 is used for press-fitting. For the single-cylinder brake cylinder, the first integrated press 701 can be used to press-fit the common cylinder body 09 and the common cylinder head.

[0339] After the common cylinder body 09 with the bushing 091 pressed and fixed on the cylinder body turntable 1301, it is continuously conveyed along the conveying direction of the double-layer automatic conveyor line. When it is conveyed to the working position of the first integrated press 701, the main piston assembly 01 after the first leather cup is pressed and installed after oil injection in the piston assembly equipment 100 is inserted into the center hole (through hole) of the common cylinder body 09 with the main piston 011 facing downward and the main piston cylinder 012 facing upward, the restoring spring is put on the main piston cylinder 012, and then the common cylinder cover is buckled; the common cylinder cover has a center hole, and the main piston cylinder 012 passes through the center hole of the common cylinder cover.

[0340] The twelfth pressure head 7012 is driven downward by the ninth driving device 7013, and the bottom surface of the twelfth pressure head 7012 abuts against the top surface of the common cylinder cover, and the portion of the main piston cylinder 012 located outside the common cylinder cover extends into the cylindrical structure of the twelfth pressure head 7012. After the common cylinder cover is pressed into place, multiple fasteners (four bolts) are manually pre-threaded, and then the electric torque wrench is used to apply torque, so that the common cylinder body 09 and the common cylinder cover can be fixed.

[0341] Of course, for the composite brake cylinder, since the station where the first integrated press machine 701 is located is close to the pre-loaded material slideway 1500 for placing the main piston assembly 01, this station can only install the main piston assembly 01 and the return spring in the common cylinder body 09, without the need to press-fit the common cylinder head. Of course, the assembly of the piston assembly and the return spring can also be carried out at other locations as needed.

[0342] Reference Fig.55 The cylinder oil injection device 800 includes a third rotary oil injection device 801 , and the structure of the third rotary oil injection device 801 is the same as that of the first rotary oil injection device 102 .

[0343] The third rotary oil spraying device 801 is used to spray oil on the inner wall of the common cylinder body 09 and the main piston assembly 01 installed therein. When in use, for the composite brake cylinder, the common cylinder body 09 after the main piston assembly 01 and the restoring spring are assembled at the station where the first integrated press 701 is located is removed from the cylinder body tray 1300 and placed in the third rotary oil spraying device 801 for oil spraying. The specific oil spraying process is the same as the oil spraying process of the first rotary oil spraying device 102 mentioned above, and will not be repeated here. For the single-cylinder brake cylinder, after the main piston assembly 01 and the restoring spring are installed in the common cylinder body 09 at the station where the first integrated press 701 is located, the common cylinder body 09 is first removed from the cylinder body tray 1300, placed in the third rotary oil spraying device 801 for oil spraying, and then placed back on the cylinder body tray 1300, and the common cylinder head is press-fitted by the first integrated press 701.

[0344] Reference Fig.56 The intermediate assembly equipment 900 includes a second integrated press 901 and a first electric torque wrench 902 . The structure of the second integrated press 901 is the same as that of the first integrated press 701 .

[0345] The intermediate body is a component connecting the parking cylinder 04 and the common cylinder, and its structure is an existing structure. The second integrated press 901 is used to press the intermediate body and the common cylinder body 09, and the first electric torque wrench 902 is used to perform torque tightening operations. The above-mentioned single-cylinder brake cylinder does not need this station, only the composite brake cylinder needs this station. For the composite brake cylinder, the main piston assembly 01 and the return spring are installed in the common cylinder body 09 at the station where the first integrated press 701 is located, and the oil injection operation is performed using the third rotating oil injection device 801. The common cylinder body 09 after oil injection is placed on the cylinder body turntable 1301, and when it is transported to the corresponding station of the second integrated press 901, the intermediate body is placed on the common cylinder body 09. The intermediate body has a center hole, and the main piston cylinder 012 passes through the center hole of the intermediate body. The intermediate body is pressed down by the second integrated press machine 901, at which time the twelfth pressure head 7012 of the second integrated press machine 901 abuts against the top surface of the intermediate body, and the portion of the main piston cylinder 012 outside the top surface of the intermediate body extends into the cylindrical structure of the twelfth pressure head 7012. After the intermediate body is pressed into place, multiple fasteners (four bolts) are manually pre-threaded, and then the first electric torque wrench 902 is used to apply torque, so that the intermediate body and the common cylinder body 09 can be fixed.

[0346] Reference Fig.57 The front end cover assembly equipment 1000 includes a front end cover automatic installation device 1001 and a second electric torque wrench 1002. The front end cover automatic installation device 1001 is used to pre-press and rotationally assemble the front end cover 010 and the main piston cylinder 012, and the second electric torque wrench 1002 is used to perform torque tightening operations to tighten the front end cover 010 in the main piston cylinder 012.

[0347] Reference Fig.58 The front end cover automatic installation device 1001 includes a ninth support frame 10011, a thirteenth pressure head 10012 and a tenth driving device 10113 arranged on the ninth support frame 10011. The thirteenth pressure head 10012 is a cylindrical pressure head and a magnet is embedded in the cylindrical pressure head for adsorbing the front end cover 010 of the brake cylinder; the tenth driving device 10113 is connected to the thirteenth pressure head 10012 and can drive the thirteenth pressure head 10012 to rotate and move up and down.

[0348] The front end cover 010 is a cylindrical structure with a top surface and an open bottom, and its top surface has a central hole. The outer wall of the front end cover 010 has an external thread, which is an existing structure. The thirteenth pressure head 10012 has a magnet that can absorb the front end cover 010, and the operation is simple. The specific assembly process is:

[0349] For the compound brake cylinder, the common cylinder body 09 assembled by the intermediate assembly equipment 900 is transported along the conveying direction of the upper conveyor line to the workstation where the front end cover automatic installation device 1001 is located, and the guide nut assembly 02 after the first retaining ring 025 is pressed by the above-mentioned guide nut pressing device 103 or the gap adjuster 03 after the second retaining ring is pressed by the above-mentioned gap adjuster pressing device 201 is manually inserted into the main piston cylinder 012 and inserted to the bottom, so that the guide nut assembly 02 or the gap adjuster 03 rests on the bowl-shaped bottom of the main piston 011. At this time, the guide nut assembly 02 or the gap adjuster 03 is completely located in the main piston cylinder 012.

[0350] The front end cover 010 is magnetically attracted to the bottom of the thirteenth pressure head 10012, and an inner spring is inserted in the front end cover 010. The tenth driving device 10113 is started to drive the thirteenth pressure head 10012 to move downward and rotate, overcome the elastic force of the inner spring, and pre-compress the front end cover 010 and screw it into the main piston cylinder 012. At this time, the two ends of the inner spring are respectively pressed against the top surface of the front end cover 010 and the top end surface of the guide nut 021 in the guide nut assembly 02 or the top end surface of the center tube of the clearance adjuster 03. After that, the front end cover 010 is manually torqued with a second torque wrench to tighten it.

[0351] For a single-cylinder brake cylinder, the common cylinder body 09 assembled by the cylinder body feeding device is transported along the conveying direction of the upper conveyor line to the workstation where the front end cover automatic installation device 1001 is located, and the guide nut assembly 02 after the first retaining ring 025 is pressed by the above-mentioned guide nut pressing device 103 or the clearance adjuster 03 after the second retaining ring is pressed by the above-mentioned clearance adjuster pressing device 201 is manually inserted into the main piston cylinder 012. The process of installing the front end cover 010 later is the same as the process of installing the front end cover 010 in the aforementioned composite brake cylinder, which will not be repeated here.

[0352] When installing the front end cover 010, it is necessary to overcome the spring force of the inner spring to press it downward, and at the same time, it needs to be rotated into the matching threaded hole (i.e., the inner threaded hole of the main piston cylinder 012). The manual screwing method in the prior art is slow to assemble, inefficient, and inconvenient to operate. In this embodiment, the front end cover automatic installation device 1001 is used to first perform pre-compression rotation assembly, and the front end cover 010 can be automatically installed, and then a torque wrench is used to tighten the torque, which reduces the labor intensity and has higher assembly efficiency.

[0353] The tenth driving device 10113 mentioned above may include a cylinder and a motor, and the cylinder is used to drive the thirteenth pressing head 10012 to move up and down, and the motor is used to drive the thirteenth pressing head 10012 to rotate, so as to achieve simultaneous rotation during the pressing process, and install the front end cover 010 in place.

[0354] Generally, a plurality of protrusions (four protrusions) are provided at circumferential intervals on the bottom side wall of the thirteenth pressure head 10012. When the front end cover 010 is adsorbed, they can be aligned vertically with the four notches 101412 on the front end cover 010 to ensure that the front end cover 010 is centered and concentric.

When the flipping disc 11011 is in a horizontal state, it can dock with the upper conveyor line. The eleventh driving device 11012 is connected to the flipping disc 11011 and can drive the flipping disc 11011 to flip.

[0356] The auxiliary flipping device 1101 is used to flip the tray to a certain angle so as to flip the intermediate body and the common cylinder body 09 as a whole, so as to facilitate the assembly of the parking cylinder 04. For the composite brake cylinder, the intermediate body and the common cylinder body 09 are coaxially arranged, and the parking cylinder 04 needs to be installed on the side of the intermediate body and connected to the multiple mounting holes (four mounting holes) on the side of the intermediate body through fasteners; after the front end cover 010 is assembled by the front end cover assembly equipment 1000, the axis of the intermediate body and the common cylinder body 09 is in a vertical state, and when it is further transported to the auxiliary flipping device 1101, the common cylinder body 09 is transported to the flipping plate 11011, and the flipping plate 11011 is flipped 90° by the eleventh driving device 11012. , so that the axis of the common cylinder body 09 is horizontal, the multiple mounting holes on the side of the intermediate body can be facing upward, which is convenient for the operator to place the first type of parking cylinder or the second type of parking cylinder on the intermediate body (the wedge body 05 installed on the parking cylinder 04 extends into the intermediate body), and pass multiple fasteners (four bolts), and then use the above-mentioned second electric torque wrench 1002 to apply torque to complete the fixation of the parking cylinder 04 and the intermediate body; after the installation is completed, the eleventh drive device 11012 is used to drive the flip disk 11011 to flip back to a horizontal state.

[0357] Generally, at the workstation corresponding to the front end cover automatic installation device 1001, the guide nut component 02 is assembled, and the first type of parking cylinder is selected to be installed at the workstation where the auxiliary flipping device 1101 is located; if at the workstation corresponding to the front end cover automatic installation device 1001, the clearance adjuster 03 is assembled, and the second type of parking cylinder is selected to be installed at the workstation where the auxiliary flipping device 1101 is located.

[0358] In order to facilitate the fixation of the common cylinder body 09 on the flipping plate 11011, the auxiliary flipping device 1101 also includes a first positioning and lifting device. A plurality of rollers 110111 are provided on the flipping plate 11011. The first positioning and lifting device includes a first lifting drive device 11013 and two groups of first positioning block groups arranged on both sides of the flipping plate 11011; the first lifting drive device 11013 is arranged on the bottom surface of the flipping plate 11011, and can lift the pallet upward so that the top surface of the pallet rests on the bottom surfaces of the two groups of first positioning block groups.

[0359] The upper conveyor line is disconnected at the position of the auxiliary flip device 1101, and the flip plate 11011 is in a horizontal state and just docks with the upper conveyor line. The axes of the multiple rollers 110111 on the flip plate 11011 are perpendicular to the conveying direction of the upper conveyor line. Fig.60 The flip plate 11011 includes a flip bottom plate 20311 and two flip side plates 20313 connected to both sides of the flip bottom plate 20311. Both ends of each roller 110111 are rotatably connected to the two flip side plates 20313, and the axis of the roller 110111 is perpendicular to the plate surface of the flip side plate 20313. Each group of first positioning blocks includes at least two first positioning blocks 11014, each first positioning block 11014 is fixed on the top of the corresponding flip side plate 20313. In this embodiment, there are four first positioning blocks 11014, which are symmetrically arranged on the two flip side plates 20313. The first lifting drive device 11013 can be, for example, a cylinder, and the number can be, for example, two and symmetrically arranged along the length direction of the flip plate 11011. When the common cylinder body 09 is transported along the conveyor line to the roller 110111 of the flip plate 11011, the first lifting drive device 11013 lifts the pallet upward to separate the pallet from the rollers 110111. At this time, the bottom surface of each first positioning block 11014 abuts against the top surface of the pallet. The pallet is clamped and fixed between the first lifting drive device 11013 and the first positioning block 11014 by utilizing the upper push of the first lifting drive device 11013 and the downward pressure of the first positioning block 11014 to achieve fixation.

[0360] In order to facilitate the movement of the flip disk 11011, a support base 11015 is fixedly provided on the work surface of the parking assembly equipment, and the flip disk 11011 is arranged above the support base 11015 and is rotatably connected to the top surface of the support base 11015 through a rotating shaft 11016; the eleventh driving device 11012 is a cylinder, and the cylinder body of the eleventh driving device 11012 is hinged to the bottom of the support base 11015 (the cylinder body of the eleventh driving device 11012 is located below the support base 11015), the end of the piston rod of the eleventh driving device 11012 is hinged to the bottom of the flip disk 11011, and the rotating shaft 11016 is located between the hinge point B between the eleventh driving device 11012 and the support base 11015 and the hinge point A between the eleventh driving device 11012 and the flip disk 11011.

[0361] The cylinder body of the eleventh driving device 11012 is located below the work surface of the parking cylinder assembly device 1100, and the hinge axes at the two hinge points and the axis of the rotating shaft 11016 are perpendicular to the conveying direction of the upper conveyor line. The piston rod of the eleventh driving device 11012 is extended or shortened to drive the flip plate 11011 to flip between the horizontal position and the vertical position.

[0362] Generally, the eleventh driving device 11012 can be Fig.60 The two cylinders shown in FIG. 1 include two cylinders arranged in parallel and spaced apart. When the two cylinders are in the extended state, as shown in FIG. Fig.61 As shown, the flip plate 11011 is in a horizontal position. When the parking cylinder 04 needs to be assembled, the two cylinders are retracted at the same time. Fig.61 In the orientation shown in the figure, the left side of the flip plate 11011 is lowered and the right side is raised, so that the pallet is tilted at a certain angle, which facilitates the assembly of the parking cylinder 04 to the intermediate body and reduces the intensity of manual handling.

[0363] Reference Fig.62 The above-mentioned connecting rod assembly assembly equipment 1200 is mainly used to assemble the connecting rod assembly 08, and install the connecting rod assembly 08 assembled by the connecting rod assembly equipment 500 into the center hole of the top surface of the front end cover 010.

[0364] Specifically, when the common cylinder body 09 is transported to the corresponding workstation of the connecting rod assembly assembly equipment 1200, for the compound brake cylinder and the single-cylinder brake cylinder, the lead screw 083 of the connecting rod assembly 08 needs to be manually inserted through the center hole of the top surface of the front end cover 010, passed through the center hole of the guide nut assembly 02 or the gap adjuster 03, and threadedly connected with the guide nut assembly 02 or the gap adjuster 03 until the connecting rod 081 in the connecting rod assembly 08 abuts against the top surface of the front end cover 010. After the connecting rod assembly 08 is installed, it is disassembled along the brake cylinder lower line conveyor line 1900 that is docked with the upper conveyor line, and the empty pallet continues to move in a cycle along the lower conveyor line.

[0365] Further, see Fig.64 The clamp unit brake cylinder assembly production line also includes a plurality of movable material trays 1800 , each material tray 1800 is provided with an electronic ink screen label for displaying the brake cylinder serial number information corresponding to the current material tray 1800 in real time.

Each pre-installation station corresponds to at least one material tray 1800. Each material tray 1800 will be placed on the corresponding conveyor cart to be transported to the designated station. Use the station-specific material tray 1800 to load the five pre-installation stations. The materials in the material tray 1800 are only used for the corresponding pre-installation station. After the assembly is completed, all the parts in the material tray 1800 are also used up, which can play a role in error prevention; an electronic ink screen label is installed on each material tray 1800. Through the corresponding control system, the electronic ink label can display the brake cylinder serial number information corresponding to the current material tray 1800 in real time, which is convenient for operators to identify and play a role in error prevention.

[0368] The five pre-assembly stations and seven final assembly stations are equipped with intelligent material racks 1600 and visual process panels 1700. Each station is equipped with a standard material picking monitoring device (i.e., intelligent material rack 1600). The intelligent material rack 1600 can monitor the material picking action according to the assembly operation requirements to avoid missing or over-installing standard parts and ensure assembly quality. The visual process panel 1700 is used for assembly operation process guidance. For example, it can display the current work content and precautions of the station, and conduct self-inspection, mutual inspection confirmation, and work completion confirmation.

[0369] Specifically, according to the requirements of the assembly operation, the type and quantity of materials used at each workstation can be determined. Sensors 16002 are provided at the positions corresponding to each material storage tank box 16001 on the intelligent material rack 1600. When the operator takes the material, the sensor 16002 will record the position and number of times the material is taken. When the material is not taken or the number of times taken is incorrect, the control system will give an alarm. The sensor 16002 can be, for example, an infrared sensor that can sense and detect the movement of the hand. When it is blocked, it records a take. The specific detection principle is the existing technology. A slide can be provided on the intelligent material rack 1600, and the material storage tank box 16001 can slide on the slide.

[0370] These five pre-assembly stations and seven final assembly stations are all provided with a workbench, and the workbench has a work surface. Each device of the piston assembly equipment 100 is fixed on its work surface; each device of the wedge assembly equipment 200 is fixed on its work surface; the camera 3012 of the K-ring detection device 301 of the parking piston assembly equipment 300 is located below the work surface, and the second rotary oil injection device 302, the intelligent material rack 1600 and the visual process panel 1700 of the parking piston assembly equipment 300 are all fixed on the work surface of the parking piston assembly equipment 300; each device of the hand relief assembly equipment 400 is fixed on its work surface; each device of the connecting rod assembly equipment 500 is fixed on its work surface.

The vertical racks are arranged close to the second side of the double-layer automatic conveyor line, and respective visual process panels 1700 can be arranged on their respective vertical racks.

[0373] The cylinder loading device 700, the intermediate assembly device 900, the front cover assembly device 1000, the parking cylinder assembly device 1100 and the connecting rod constitute the final assembly device 1200. The work tables of the five final assembly stations are all provided with sub-conveyor lines 1400 for pallet transportation. Each sub-conveyor line 1400 includes two chains arranged in parallel and at intervals. The work tables of the five final assembly stations are sequentially docked along the conveying direction of the upper conveyor line, and the sub-conveyor lines 1400 on the five work tables are docked with each other to form the above-mentioned upper conveyor line.

[0374] The work surfaces of the five final assembly stations (specifically, on the vertical frames) are all provided with pre-loading material chutes 1500, which are used to transport the pre-loading station assembly parts to the final assembly station. Each pre-loading material chute 1500 is arranged downwardly from the second side of the double-layer automatic conveyor line to the first side, and a blocking plate is provided at the lower end of the pre-loading material chute 1500, so that the assembly parts of the pre-loading station can be continuously slid into the pre-loading material chute 1500 and limited by the blocking plate. The number of pre-loading material chutes 1500 of each station is determined according to needs, and in this embodiment, there are multiple pre-loading material chutes. The assembly parts assembled in each pre-loading station are sent to the final assembly station through the pre-loading material chute 1500 of the corresponding final assembly station, and the five final assembly stations assemble the pre-assembled parts in turn. The operator can directly take the assembly parts from the pre-loading material chute 1500 at the final assembly station, which is more convenient.

[0375] In addition, the bottom of the workbenches of the five assembly stations are all provided with a return plate table, and each return plate table is provided with a return plate conveyor line. The return plate conveyor lines on the five work tables are connected to each other to form the above-mentioned lower conveyor line.

[0376] In this embodiment, the length direction of the workbench of the above five assembly stations is arranged along the conveying direction of the upper conveyor line. Figure 1 The cylinder bushing pressing device 600 is arranged in front of the cylinder feeding device 700, and the cylinder oil injection device 800 is arranged behind the cylinder feeding device 700; at the same time, the length direction of the workbench of the five pre-installation stations is perpendicular to the conveying direction of the upper conveyor line, and according to Figure 1 By arranging the equipment in the order of the above, and installing the above-mentioned corresponding equipment at each pre-assembly station and the final assembly station as described above, the time taken by each of the five pre-assembly stations and the five final assembly stations on the upper conveyor line, as well as the total time taken by the two equipments, the cylinder bushing pressing equipment 600 and the cylinder oil injection equipment 800, can be basically the same, so as to achieve a balanced beat. Based on the MTM standard working time analysis, the process balance rate of the five pre-assembly stations, the five final assembly stations on the conveyor line, and the final assembly stations outside the conveyor line (cylinder bushing pressing equipment 600 and cylinder oil injection equipment 800) is not less than 90%.

[0377] Furthermore, second positioning and lifting devices are provided at positions on the upper conveyor line corresponding to the cylinder loading equipment 700, the intermediate body assembly equipment 900, the front end cover assembly equipment 1000 and the connecting rod assembly equipment 1200. The upper conveyor line includes two upper conveyor chains arranged in parallel and spaced apart. The second positioning and lifting device includes a second lifting drive device 3015 and two groups of second positioning block groups arranged on the outside of the two conveyor chains; the second lifting drive device 3015 is arranged on the corresponding work surface and is located between the two conveyor chains, and can lift the pallet upward so that the top surface of the pallet rests against the bottom surfaces of the two groups of second positioning block groups.

[0378] The second lifting drive device 3015 can be, for example, a cylinder, and the number thereof is determined as required; each group of second positioning block groups includes at least two second positioning blocks, which are fixed on the outside of the upper conveying chain and are higher than the upper conveying chain. Each second positioning lifting device specifically corresponds to the preset position of the upper conveying line on the working surface of the first integrated press 701 in the cylinder loading device 700, the second integrated press 901 in the intermediate assembly device 900, the front end cover automatic installation device 1001 in the front end cover assembly device 1000, and the connecting rod assembly device 1200. When the pallet moves to the position of each second positioning lifting device along the conveying direction of the upper conveying line, the second lifting drive device 3015 lifts the pallet upward to make the pallet detach from the upper conveying chain. At this time, the bottom surface of each second positioning block is against the top surface of the pallet, and the pallet is clamped and fixed between the second lifting drive device 3015 and the second positioning block by the upper push of the second lifting drive device 3015 and the downward pressure of the second positioning block to achieve fixation.

[0379] Furthermore, on the upper conveyor line, corresponding to the positions of the cylinder loading equipment 700, the intermediate body assembly equipment 900, the front cover assembly equipment 1000, the parking cylinder assembly equipment 1100 and the connecting rod assembly equipment 1200, there are stop blocks that can be raised and lowered, and the stop blocks are located between the two upper conveyor chains.

[0380] When the pallet is transported to a certain assembly station along the upper conveyor line, the corresponding stop block rises and blocks the pallet to limit the stop position of the pallet and ensure that the pallet stops at the specified position of the corresponding assembly station.

[0381] Furthermore, a hoist is provided at both ends of the upper conveyor line to achieve the docking of the pallet between the upper conveyor line and the lower conveyor line. The structure of the specific hoist can adopt any existing method and is not limited here.

[0382] It can be understood that the entire assembly production line also includes a control system to control the actions of each drive device 3015 and some components to achieve automatic control, which will not be repeated here. In one embodiment, the control system also includes a torque information sending and collecting system to automatically send torque instructions according to software settings, and automatically collect torque information to ensure the accuracy of the torque tightening process; specifically, according to the torque tightening requirements of the assembly operation, when torque operations are required, the system will send instructions to the corresponding electric torque wrench. After the torque is applied, the torque wrench will send the torque result to the system, which will be judged by the system to ensure the accuracy of the torque tightening process.

[0383] The entire production line uses a visual process panel 1700 to provide process guidance for assembly operations, and can achieve self-inspection and mutual inspection; an electronic ink label is set on the material tray 1800 to display the brake cylinder serial number information corresponding to the current material tray 1800 in real time; the K-ring detection device 301 is used to automatically detect the installation direction of the K-ring 0451; the disc spring push device 501 is used to push out one disc spring 07 at a time and apply oil to avoid oil leakage; when using an electric torque wrench to apply torque, the torque size can be controlled by the control system to prevent placement errors; an intelligent material rack 1600 and a sensor 16002 are set to monitor the material picking action to avoid missing or over-installing standard parts, and indicator lights can be set at the position corresponding to each material storage tank box 16001 on the intelligent material rack 1600. When the tooling currently needs to install a part, the indicator light corresponding to the corresponding material storage tank box 16001 will light up to better guide the operator. Through the coordination of these parts, the entire production line can be effectively guaranteed to prevent errors and fools during the assembly process.

[0384] In summary, the assembly line in this embodiment can improve the efficiency and capacity of the assembly process, reduce the labor intensity of personnel, realize the automated assembly of brake cylinders, and optimize the process rhythm; improve assembly efficiency, improve information recording, and strengthen quality control; improve the accuracy of assembly information and the traceability of data. It is a digital assembly line for clamp brake cylinders based on the beat balance method, which has significant improvements in assembly efficiency, error prevention, information recording, quality control, etc. It can be applied to the existing brake clamp unit products of railway locomotives and vehicles. As a key component of the basic braking device, the performance of the brake clamp unit is directly related to the running safety and ride comfort of the train. The assembly line can be used for the assembly of brake clamp unit brake cylinders, including pre-installation stations, general assembly stations, and digital information systems.

[0385] The five pre-assembly stations can be used to complete the pre-assembly of some important parts in the brake cylinder, and the seven final assembly stations can be used to assemble the pre-assembled parts onto the common cylinder body 09. The final assembly station adopts a double-layer automatic conveyor line as a whole, which can fix the brake cylinder on the pallet workbench and realize the automatic circulation of the pallet workbench; the double-layer automatic conveyor line mainly consists of a final assembly double-layer automatic conveyor line (i.e. the upper conveyor line and the lower conveyor line mentioned above), a hoist, a non-standard customized pallet (i.e. the cylinder pallet 1300 mentioned above) and a clamping and positioning device (i.e. the fixed seat 1302 and the fixed plug rod 1303 mentioned above), a parking brake cylinder auxiliary assembly device (i.e. the auxiliary flipping device 1101 mentioned above), a stop device (i.e. the stop block mentioned above), a positioning jacking device, a pallet in-situ detection control system (the upper conveyor line will simultaneously convey multiple cylinder pallets 1300, each cylinder pallet 1300 matches a brake cylinder, and the pallet in-situ detection control system is used to detect which number the pallet is), and a conveyor line electrical control system. The digital information system mainly includes a visualization process system (i.e. the visualization process panel mentioned above), a torque data sending and collection system, an intelligent error prevention system, an automatic disc spring oiling device (i.e. the disc spring pushing device 501 mentioned above), a front end cover automatic assembly device, etc.

[0386] Furthermore, from the above introduction, it can be known that brake cylinders are divided into single-cylinder brake cylinders and compound brake cylinders. There are some differences in the assembly process of the two brake cylinders. Generally speaking, the single-cylinder brake cylinder mainly uses three pre-assembly stations, namely the piston assembly equipment 100, the clearance adjuster pressing device 201 in the wedge assembly equipment 200, and the connecting rod assembly equipment 500, as well as five final assembly stations, namely the cylinder bushing pressing equipment 600, the cylinder feeding equipment 700, the cylinder injection equipment 800, the front end cover assembly equipment 1000 and the connecting rod assembly equipment 1200; the five pre-assembly stations and seven final assembly stations mentioned above will be used for the compound brake cylinder.
