Description

Technical Field

[0001] The utility model belongs to the field of compressor assembly and manufacturing, and in particular relates to equipment for automatically assembling bearings of compressors which can detect the thickness of bearings. Background Art

[0002] The working principle of the automobile air-conditioning compressor is mainly to drive the refrigerant to circulate in the air-conditioning system through the power provided by the engine. The specific process is as follows: the compressor compresses the low-temperature and low-pressure gaseous refrigerant from the evaporator into a high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser; the high-temperature and high-pressure gaseous refrigerant dissipates heat in the condenser and becomes a high-temperature and high-pressure liquid refrigerant, and then flows out into the drying bottle, the main purpose of which is to kick out water; the liquid refrigerant then enters the evaporator box, and the expansion valve in the evaporator box will turn the high-temperature and high-pressure liquid into low-temperature and low-pressure steam. In the process of changing from liquid to gas, it will absorb a lot of heat, thereby reducing the temperature in the car; the refrigerant in the evaporator box flows back to the compressor again, forming a cycle.

[0003] The main shaft is the core component of the compressor. It drives the swash plate to make the piston reciprocate in the piston cavity in the cylinder to achieve the refrigeration effect. Before installing the main shaft, it is necessary to press the sliding bearing in the cylinder to support the main shaft through the sliding bearing. The existing sliding bearing press-fitting is manual, which is performed by placing the sliding bearing directly at the bearing installation position in the cylinder for vertical direct press-fitting.

[0004] According to the search of the sliding bearing press-fitting tool disclosed in CN102029517A, a first locating pin and a second locating pin are vertically fixed on the bottom plate, and the distance between the first locating pin and the second locating pin is equal to the distance between the oil pump hole and the crankshaft hole on the crankcase cover to be assembled. A horizontal hole is opened on the upper part of the second locating pin, and a spring and a steel ball are installed in the horizontal hole. One end of the steel ball abuts against the spring, and the other end of the steel ball is limited by the closing of the horizontal hole, and a small part of the steel ball protrudes out of the closing of the horizontal hole. The oil passage of the sliding bearing is aligned with the elastically mounted steel ball on the second locating pin to achieve accurate vertical press-fitting.

[0005] The above technology has the following problems when applied to the installation of compressor sliding bearings: the thickness of the bearings is not tested before press-fitting. If the thickness does not meet the standard, it may easily lead to subsequent main shaft installation position deviation or even failure to complete the compressor assembly operation. Even if the compressor assembly operation can be completed, abnormal noise may easily occur when the compressor is working. Summary of the invention

[0018] Preferably: the press-fitting mechanism comprises a press-fitting power element, a suspension frame and a base frame, the press-fitting power element is mounted on the frame and is located directly above the conveyor line, a vertical slide is mounted on the output end of the press-fitting power element, a lifting plate, a pressing rod and a second displacement sensor are mounted on the vertical slide, the lifting plate is used to be pressed on the cylinder body and slide vertically relative to the vertical slide, the pressing rod is used to vertically press-fit the bearing, and the second displacement sensor is used to detect the displacement amount from when the lifting plate contacts the cylinder body to when the bearing is pressed;

[0022] Preferably: it also includes an oil injection mechanism, which includes a vertical linear module, a horizontal linear module and an oil injection nozzle.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] The utility model adopts a conveying track to automatically load materials at the head end through a vibrating plate, and is provided with two tracks to improve the compatibility of the equipment. A transfer mechanism is provided at the ends of the two bearing conveying tracks to convey the required bearings to the thickness detection mechanism. The thickness detection ensures that the thickness of the bearings assembled each time meets the requirements, and eliminates the problem of rework caused by inconsistent bearing thickness on the conveying track.

[0025] The utility model also has a selectively movable oil injection mechanism installed on one side of the assembly station, and the oil injection mechanism can be used to perform oil injection treatment on the bearing installation position in the cylinder, and the oil injection treatment can reduce the wear of the bearing and the cylinder body during the installation process.

[0026] The press-fitting mechanism of the utility model adopts a downward pressure power element and a lower cylinder to press-fit the bearing through a pressure rod and a socket rod. After the pressure rod contacts the upper end surface of the bearing, it moves downward together with the piston rod of the lower cylinder to vertically lower the bearing to the bearing installation position. The pressure rod presses the bearing downward, and the piston rod of the lifting cylinder retracts inward under pressure. Then the pressure rod quickly presses the bearing vertically, and the piston rod of the lifting cylinder retracts synchronously and quickly to drive the socket rod to reset to the initial position. The socket rod and the pressure rod are used to press and fix the bearing, and then they move downward together for vertical precise installation.

[0027] By clamping the bearing up and down, the stability and position accuracy of the bearing during installation can be ensured. This helps to achieve a more precise fit between the bearing and the shaft or hole, thereby improving the accuracy and reliability of the entire system. If the bearing is directly pressed without clamping, it may deform due to uneven force. Clamping the bearing up and down can ensure that the bearing is evenly stressed during the press-fitting process and reduce the possibility of deformation. The clamping operation can prevent the bearing from accidentally moving or misaligning during the press-fitting process and ensure the correct installation position. The pre-clamping operation can position the bearing faster, thereby reducing the adjustment time during the installation process and improving the installation efficiency. The clamping operation can make the connection between the bearing and the mounting seat tighter, thereby enhancing the strength and stability of the connection.

[0028] The utility model also improves the oil spray nozzle by rotating and setting the bottom nozzle obliquely upward to face downward during oil spraying, thereby preventing oil dripping from contaminating the detection platform. The pressurized body can reduce the effective volume in the top cavity, and after descending to the lowest position, the oil spray atomization effect is also good. When the oil spraying is finished, the pressurized body can reversely recover the excess atomized oil particles into the top cavity (during the elastic reset process of the elastic rope) by ascending at the first time, preventing the appearance of droplets in the cylinder body. As the pressurized body continues to ascend, the bottom nozzle will be reset under the action of the reset spring. After the bottom nozzle is reset, the oil spray nozzle will be reset to the initial position under the action of the horizontal linear module and the vertical linear module. After the oil spray nozzle is reset, the pressurized body will descend, and the elastic rope will drive the bottom nozzle to face its angle downward. The pressurized body repeats the downward action many times, and can spray the recovered oil downward and drip into the oil collection box reserved below. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0040] The conveying track 21 is arranged on one side of the conveying line 20 and is arranged perpendicular to the conveying line 20, and is used to automatically convey the required bearings;

[0041] A thickness detection mechanism, located on one side of the conveying track 21, is used to detect the thickness of the bearing;

[0043] The second transfer mechanism is located on one side of the thickness detection mechanism and is used to transfer the bearing at the thickness detection mechanism to the press-fitting station, and the movement direction is perpendicular to the conveyor line 20;

[0045] The press-fitting mechanism is located directly above the conveyor line 20 and is used to vertically press-fit the bearing into the bearing installation position in the cylinder body.

[0046] When in use, the cylinder body is transported by the conveyor line 20, and is lifted up by a pre-set supporting mechanism at the pressing station, and is separated from the conveyor line 20. The vibration plate at the head end of the conveying track 21 loads the bearing, and then squeezes the terminal bearing on it onto the transfer mechanism 1, and is transported by the transfer mechanism to the thickness detection mechanism for thickness detection. If the detection meets the requirements, it is transported by the transfer mechanism 2 to the pressing station for pressing. If it does not meet the requirements, it is concentrated in a pre-set aggregate (collection / recycling) box, and is sprayed with oil before pressing, and vertical pressing is performed after oil spraying.

[0047] Embodiment 2, as Figure 1 and Figure 2 As shown, the following improvements are made on the basis of the above embodiment: the transfer mechanism 1 includes a slide rail 22 and a slide table 23, the slide rail 22 is arranged parallel to the conveying line 20, the slide table 23 is slidably matched on the slide rail 22, and a supporting claw 24 is installed on the slide table 23, and the supporting claw 24 is used to support the bearing detached from the conveying track 21. A supporting boss is provided at the claw mouth of the supporting claw 24, and the boss width is less than or equal to the bearing thickness. The slide table 23 and the slide rail 22 form a linear module, and the driving method can be a servo motor through a lead screw nut to realize linear transmission between the two.

[0048] Embodiment 3, as Figure 1 and Figure 2 As shown, the following improvements are made on the basis of the above embodiment: the second transfer mechanism includes a second slide rail 25 and a lifting cylinder 26, the second slide rail 25 is arranged vertically on the conveyor line 20, a second slide table 27 is installed on the second slide rail 25, the lifting cylinder 26 is arranged vertically on the second slide table 27, and a pneumatic clamp 28 is installed at the end of the piston rod of the lifting cylinder 26, and the pneumatic clamp 28 is used to clamp the bearing after the thickness is detected. The second slide rail 25 and the second slide table 27 form a linear module, and the driving method can be a servo motor through a lead screw nut to achieve linear transmission between the two. The pneumatic clamp 28 is driven up and down by the lifting cylinder 26.

[0049] Embodiment 4, based on the above embodiment, makes the following improvements: Figure 1 and Figure 2 As shown, the thickness detection mechanism includes an upper mounting frame 29 and a lower mounting frame 210;

[0050] The upper mounting frame 29 is installed with a descending cylinder 211, a detection platform 212 and a displacement sensor 213. A moving frame 214 is installed at the output end of the descending cylinder 211. The moving frame 214 is vertically slidably matched on the upper mounting frame 29. The moving frame 214 is installed with a detection frame 215 through a spring. The detection frame 215 slides vertically relative to the moving frame 214. The displacement sensor 213 is installed on the moving frame 214 to detect the displacement of the detection frame 215.

[0051] The lower mounting frame 210 is installed with a lifting cylinder 216 and a lifting rod 217. The output end of the lifting cylinder 216 is installed with the lifting rod 217. The lifting rod 217 is used to move the bearing upward to the clamping station of the second transfer mechanism.

[0052] The bearing transported by the claw 24 moves to between the lifting rod 217 and the detection frame 215, and the lifting rod 217 will move upward under the action of the lifting cylinder 216, and then the lifting rod 217 will hold the bearing to a predetermined height, which is the reference plane. The downward cylinder 211 drives the movable frame 214 to descend to a predetermined height, which meets the conditions that the detection platform 215 and the supporting area of ​​the lifting rod 217 are just in contact and the spring is not deformed. Since the lifting rod 217 at the bottom is equipped with a bearing, the detection platform 215 will abut against the upper surface of the bearing and compress the spring relative to the movable frame 214. The displacement sensor 1 213 will detect the position change of the detection platform 215, and then obtain the thickness of the bearing. If the thickness meets the requirements, it will be transported to the pressing station through the transfer mechanism 2. If it does not meet the requirements, it will be transported to the pre-aggregate (collection / recycling) box. At the same time, the new bearing is re-transported by the transfer mechanism 1 and undergoes a thickness detection process until it meets the requirements. Thickness detection is to avoid the problem of thickness discrepancies in the same batch of bearings caused by the bearing manufacturer's packaging quality inspection and the problem of bearing thickness discrepancies caused by errors in the loading process. Screening before pressing can effectively avoid the disadvantage of compressor quality discrepancies caused by this problem.

[0053] Embodiment 5, based on the above embodiment, the following improvements are made: Figure 7 As shown, the press-fitting mechanism includes a press-fitting power element 218 (oil cylinder) and a base frame 220. The press-fitting power element 218 is installed on the frame 10 and is located directly above the conveyor line 20. A vertical slide 221 is installed at the output end of the press-fitting power element 218. The vertical slide 221 slides vertically relative to the frame 10. A lifting plate 222, a pressing rod 223, and a second displacement sensor 224 are installed on the vertical slide 221. The lifting plate 222 is used to be pressed on the cylinder body and slide vertically relative to the vertical slide 221. The pressing rod 223 is used to vertically press the bearing. The second displacement sensor 224 is used to detect the displacement amount from when the lifting plate 222 contacts the cylinder body to when the bearing is pressed;

[0054] A lower cylinder 225 is installed on the bottom frame 220, and a socket rod 226 is installed on the output end of the lower cylinder 225. The socket rod 226 is used to hold the bearing.

[0055] The lower cylinder 225 moves the socket rod 226 upward to carry the bearing, the pneumatic clamp 28 releases the bearing and resets it, the downward pressure power element 218 drives the vertical slide 221 downward, the lifting plate 222 contacts the cylinder body, and the end face of the pressure rod 223 abuts against the upper end face of the bearing at the same time;

[0056] The pressure rod 223 moves downward to press the bearing into the bearing installation position inside the cylinder body, and the second displacement sensor 224 detects the height change of the lifting plate 222 relative to the vertical slide 221, thereby detecting the bearing press depth;

[0057] When the pressure rod 223 presses the bearing, after the pressure rod 223 hits the upper end surface of the bearing, it moves downward together with the piston rod (socket rod 226) of the lower cylinder 225. At this time, the bearing is in a tightened state. The bearing is lowered vertically to the bearing installation position. The pressure rod 223 can press the bearing down first, and the piston rod of the lower cylinder 225 retracts inward under pressure. This action will not affect the subsequent use of the lower cylinder 225, about 1-2 mm. Then the pressure rod 223 quickly presses the bearing vertically, and the piston rod of the lower cylinder 225 retracts synchronously and quickly to drive the socket rod 226 to return to its initial position.

[0058] The compression rod 223 and the socket rod 226 can also be used to directly press the compressed bearing vertically.

[0059] like Figure 7 and Figure 8 As shown,

[0060] The frame 10 is provided with an upper guide sleeve 227, which is sleeved on the outer side of the pressure rod 223. The bottom frame 220 is provided with a lower guide sleeve 228, which is sleeved on the outer side of the socket rod 226.

[0061] The upper guide sleeve 227 is provided with a guide structure 1, the lower guide sleeve 228 is provided with a guide structure 2, and the pressure rod 223 and the socket rod 226 are both provided with guide pins, and the guide pins are respectively adapted to the corresponding guide structures.

[0062] Through the position of the guide pin in the guide structure, the pressure rod 223 and the socket rod 226 are driven to move the compressed bearing when they move downward at the same time, thereby realizing the downward press-fitting of the pressure rod 223 and the socket rod 226 to press the bearing.

[0063] Embodiment 6, based on the above embodiment, the following improvements are made: Figure 1 , 4As shown in Figures 5 and 6, the oil injection mechanism includes a vertical linear module 30, a horizontal linear module 40 and an oil spray nozzle 50. The oil spray nozzle 50 has a pump body with extraction and atomization spraying effect. The vertical linear module 30 is used to adjust the vertical height of the oil spray nozzle 50. The horizontal linear module 40 is used to adjust the horizontal distance between the oil spray nozzle 50 and the bearing installation position in the cylinder body. The oil spray nozzle 50 is connected to the lubricating oil tank via a hose for atomization spraying of lubricating oil.

[0064] Embodiment 7, based on the above embodiment, the following improvements are made: the fuel injection nozzle 50 includes a top cavity 51 and a bottom nozzle 52;

[0065] The bottom nozzle 52 is hingedly installed on one side of the bottom of the top cavity 51, and the two are connected by a hose. The side of the top cavity 51 is externally connected to a lubricating oil tank through the hose, and the switch valve is arranged on the hose. A pressurizing body 53 movable along the inner wall is arranged in the upper area inside the top cavity 51. A secondary cylinder is installed on the top of the pressurizing body 53, and the secondary cylinder is installed on the horizontal linear module. The pressurizing body 53 is used to reduce the internal space of the top cavity 51. The pressurizing body 53 is used to pressurize and atomize the lubricating oil fed into the top cavity 51 through the pipeline and spray it downward on the bearing installation position in the cylinder body;

[0066] A fixed pulley 54 is provided on the side of the top cavity 51, an elastic rope 55 is connected to the pressurizing body 53 and is wrapped around the fixed pulley 54 for connecting to the bottom nozzle 52, and a return spring 56 is connected between the hinged side of the bottom nozzle 52 near the end position and the top cavity 51. When spraying oil, the bottom nozzle 52 turns from upward to downward.

[0067] The reset spring 56 is provided with two groups, respectively located on both sides of the hinge node, and the distance between the installation node of the reset spring 56 and the top cavity 51 and the axis of the top cavity 51 is equal to the distance between the bottom nozzle 52 and the hinge node of the top cavity 51 and the axis of the top cavity 51.

[0068] A limit block 57 is installed on the top cavity 51 to limit the maximum deflection angle. When the bottom nozzle 52 is at the maximum deflection angle, the axes of the bottom nozzle 52 and the top cavity 51 are collinear.

[0069] By rotating the bottom nozzle which is inclined upward to a vertical downward setting during oil spraying, the detection platform can be prevented from being polluted by dripping oil. The pressurized body can reduce the effective volume in the top cavity, and ensure the atomization effect of oil spraying after descending to the lowest position. When the oil spraying is finished, the pressurized body can reversely recover the excess atomized oil particles into the top cavity (during the elastic reset process of the elastic rope) by ascending at the first time to prevent the appearance of droplets in the cylinder. As the pressurized body continues to ascend, the bottom nozzle will be reset under the action of the reset spring. After the bottom nozzle is reset, the oil spray nozzle will be reset to the initial position under the action of the horizontal linear module and the vertical linear module. After the oil spray nozzle is reset, the pressurized body will descend again, and the elastic rope will drive the bottom nozzle to face vertically downward, keeping its bottom nozzle facing vertically downward. The pressurized body repeats the downward action (elastic deformation process of the elastic rope) many times, and can spray the recovered oil downward and drip into the oil collection box reserved below.

[0070] An assembly process for a compressor bearing, the assembly steps are as follows:

[0071] Bearing loading:

[0072] A vibrating plate is provided at the head end of the conveying track 21, and the bearing at the end of the conveying track 21 is squeezed onto the claw 24 at the end of the conveying line 20 through the vibrating plate.

[0073] transport:

[0074] The slide table 23 slides horizontally along the slide rail 22 to move the claw 24 supported by the bearing to the thickness detection point between the lifting rod 217 and the detection table 212;

[0075] Thickness detection:

[0076] The piston rod of the lifting cylinder 216 drives the lifting rod 217 upward to the set height. During the upward process, the bearing in the claw 24 is supported. At the same time, the lifting cylinder 26 drives the pneumatic clamp to move to the height of the bearing. The downward cylinder 211 drives the moving frame 214 downward to set the displacement. During the downward process, the detection frame 215 will contact the bearing and squeeze the spring. The displacement sensor will detect the displacement of the detection frame 215, and then obtain the bearing thickness value. After the detection is completed, the pneumatic clamp clamps the bearing;

[0077] The bearings that do not meet the thickness requirements will be uniformly transported to the recycling box, and the above steps will be repeated until the bearings that meet the thickness requirements appear. The bearings that meet the thickness requirements are then transported to the next process.

[0078] Oil injection:

[0079] The horizontal linear module 40 moves the oil spray nozzle 50 to the top of the cylinder body, and the vertical linear module 30 moves the oil spray nozzle 50 down to the bearing installation position in the cylinder body to spray oil. After completion, the vertical linear module 30 resets the oil spray nozzle 50 to the initial height, and the horizontal linear module 40 resets the oil spray nozzle 50 to the initial position;

[0080] delivery:

[0081] The lifting cylinder 26 drives the pneumatic clamp upward to the initial height via the piston rod;

[0082] The slide rail 25 and the slide table 27 move the bearing that meets the thickness requirements to the top of the cylinder body;

[0083] The lifting cylinder 26 goes down again, and at the same time, the piston rod of the lower cylinder 225 drives the socket rod 226 to penetrate the hole of the cylinder body and emerge from the top, holding the clamped bearing. The pneumatic clamp releases the bearing and resets it to the initial height first, and then resets it to the initial state through the slide rail 25 and the slide table 27;

[0084] Press Fitting:

[0085] The downward pressing power element 218 drives the vertical slide 221 downward;

[0086] When the lifting plate 222 contacts the cylinder body, the end surface of the pressing rod 223 abuts against the upper end surface of the bearing at the same time;

[0087] The pressure rod 223 moves downward to press the bearing into the bearing installation position inside the cylinder body, and the displacement sensor 224 is used to detect the bearing press depth;

[0088] When the pressure rod 223 presses the bearing, after the pressure rod 223 hits the upper end surface of the bearing, it moves downward together with the piston rod of the lower cylinder 225, lowering the bearing vertically to the bearing installation position. The pressure rod 223 presses the bearing downward, and the piston rod of the lifting cylinder 26 retracts inward under pressure. Then the pressure rod 223 quickly presses the bearing vertically, and the piston rod of the lifting cylinder 26 retracts synchronously and quickly to drive the socket rod 226 to return to its initial position.

[0089] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this.

Equivalent replacement or change based on the technical solution and inventive concept of the utility model should be included in the protection scope of the utility model.
