Description

Technical Field

[0001] The utility model relates to the technical field of press assembling machines, in particular to a feeding mechanism of a press assembling machine. Background Art

[0002] The assembly between bearing seats and bearings is often achieved by a press-fitting machine, achieving interference fit. As described in Chinese Patent Publication No. CN109968280B, titled "A Fully Automatic Bearing Press-Fitting Machine," its main structure includes: a feeding mechanism fixedly mounted on a machine frame for feeding bearings; a conveying mechanism fixedly mounted on the machine frame for conveying bearing seats to a designated workstation; a loading mechanism fixedly mounted on the machine frame for loading bearings; a lifting mechanism fixedly mounted in the middle of the machine frame, located below the loading mechanism, for lifting the bearing seats to a designated position; and a pressing mechanism fixed on the frame, located above the loading mechanism, for pressing down on the bearings to complete the press-fitting process.

[0003] In actual implementation, due to the large height difference between the discharge end of the bearing seat processing platform and the conveying mechanism of the press used to load the bearing seat, after the bearing seat processing platform completes the processing of the bearing seat, if the material guide rail is directly used to connect the discharge end of the processing platform with the feed end of the conveying mechanism, it is often difficult to accurately convey the bearing seat to the corresponding loading station of the conveying mechanism due to the large potential energy of the bearing sliding on the material guide rail, which makes it difficult to grab the bearing seat from the loading station to the pressing station of the press during the subsequent mechanical grabbing process. In addition, if Figure 5 and Figure 6 The boss-type bearing seat shown in the figure has a raised boss a1 on its bearing seat a. In order to facilitate the precise positioning of the bearing and the bearing seat a before press-fitting, the bearing seat a is often loaded with the boss a1 facing downward. However, the bearing seat a discharged from the discharge end of the processing platform is discharged with the boss a1 facing upward, which further increases the difficulty and convenience of transporting the bearing seat a, and therefore needs to be solved urgently. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a press loading mechanism, which can conveniently and accurately transfer the bearing seat from the processing platform to the loading station of the press loading mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A loading mechanism for a press machine includes a flip pipe that transfers a bearing seat on a processing platform belt line to a loading platform of a first loading mechanism. The flip pipe is distributed in a gradually downwardly inclined manner. On the vertical plane where the pipe path of the flip pipe is located, its inclined tail end is a downwardly rotating arc structure, and the end of the rotating section points to the loading station of the loading platform, so that the bearing seat sliding in the flip pipe can be flipped in the rotating section; a gate mechanism that can stop the bearing seat is provided at the rotating lower part of the rotating section.

[0007] As a further solution of the present invention: baffles are provided on both sides of the table top of the loading platform at the end outlet of the flip pipe, the two baffles are distributed in parallel, and the gap between the two baffles forms a guide channel for the sliding of the bearing seat, the guide channel has a trumpet-shaped open structure on the side close to the flip pipe, and a buffer block is provided on the side of the guide channel away from the flip pipe, and the semi-enclosed area formed by the buffer block and the two baffles constitutes the loading station.

[0008] As a further solution of the present invention: a long hole for accommodating the boss is provided on the table top of the loading platform at the loading station, and the length direction of the hole is arranged along the length direction of the guide channel.

[0009] As a further solution of the present invention: the baffle is driven by a lifting cylinder and can slide in a vertical direction to below the table surface of the loading platform.

[0010] As a further solution of the present invention: the buffer block is made of nylon, and an elastic buffer is provided on the side of the buffer block away from the diversion channel.

[0011] As a further solution of the present invention: the gate mechanism includes a gate cylinder fixed on the flip pipe, and the telescopic end of the gate cylinder is fixed with a gate plate that can extend into the inner cavity of the flip pipe and block the sliding of the bearing seat.

[0012] As a further solution of the present invention: a material distribution mechanism is installed on the flip pipe near the processing platform belt line, and the material distribution mechanism controls the time interval for the bearing seat to enter the rotary section.

[0013] As a further solution of the present invention: the material dividing mechanism includes a first material dividing plate and a second material dividing plate driven by a first material dividing cylinder and a second material dividing cylinder respectively, the first material dividing plate and the second material dividing plate are distributed at intervals and can movably separate and flip the inner cavity of the pipe, and the interval between the plate surfaces of the first material dividing plate and the second material dividing plate is adapted to the outer diameter of the bearing seat.

[0014] As a further solution of the present invention: a plurality of viewing windows are provided on the side wall of the flip pipe.

[0015] As a further solution of the present invention: a clamping claw feeding module is installed on the first feeding mechanism to transfer the bearing seat on the feeding station to the pressing station of the pressing machine.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The processing platform belt line is connected to the loading platform's loading station by flipping the pipe support. The rotating section of the flip pipe allows the bearing seat to be directly flipped during the conveying process. In addition, a gate mechanism is installed at the lower part of the rotating section to stop the bearing seat. The gate mechanism stops and then releases the bearing seat, reducing the gravitational potential energy of the bearing seat and, in turn, the kinetic energy of the bearing seat moving to the loading platform, so that the bearing seat can be accurately positioned at the loading station of the loading platform.

[0018] 2. The semi-enclosed loading station formed by the buffer block and two baffles on the loading platform can guide and buffer the bearing seat discharged from the flip pipe, ensuring that the bearing seat is accurately transported to the loading station.

[0019] 3. A long hole for accommodating the boss is provided on the loading platform's surface at the loading station. The length of the long hole is arranged along the length of the guide channel, so that when the bearing seat slides in the guide channel, its boss always slides in the long hole, further positioning the bearing seat while ensuring the sliding stability of the bearing seat.

[0020] 4. The baffle is movably connected to the loading platform. When the bearing seat on the loading station needs to be transferred to the pressing station of the press, the baffle can slide down to the bottom of the loading platform without hindering the transfer process.

[0021] 5. A material distribution mechanism is installed on the turning pipe near the processing platform belt line. The material distribution mechanism controls the time interval for the bearing seat to enter the gyroscopic section, which can prevent a large amount of bearing seats from accumulating in the turning pipe.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] For ease of understanding, the specific structure and working mode of the present invention are further described below with reference to the accompanying drawings:

[0035] The specific structure of the utility model refers to Figure 1-10 As shown, its main structure includes a turning pipe 11 for transferring the bearing seat a on the processing platform belt line 20 to the loading platform 12 of the first loading mechanism 10. Figure 1As shown, the turning pipe 11 is arranged in a gradually downwardly inclined manner, so that the bearing seat a transported into the turning pipe 11 by the processing platform belt line 20 will gradually slide downward along the inner cavity of the turning pipe 11 under the action of its own gravity; further, on the vertical plane where the pipe path of the turning pipe 11 is located, its inclined tail end is a downwardly rotating arc structure, and the end of the rotating section points to the loading station of the loading platform 12, so that the bearing seat a sliding in the turning pipe 11 is turned over in the rotating section, thereby achieving the simultaneous operation of transporting and turning the bearing seat a. In addition, in order to reduce the kinetic energy of the bearing seat a sliding into the loading platform 12, a gate mechanism 17 that can stop the bearing seat a is provided at the lower part of the rotating section. The gate mechanism 17 stops the bearing seat a and then releases it, reducing the gravitational potential energy of the bearing seat a, and further reducing the kinetic energy of the bearing seat a moving to the loading platform 12, so that the bearing seat a can be accurately positioned at the loading station of the loading platform 12.

[0036] Further, such as Figure 4 As shown, the loading station is composed of a semi-enclosed area formed by a buffer block 15 and two baffles 13. Specifically, baffles 13 are provided on both sides of the table top of the loading platform 12 at the end outlet of the flip pipe 11. The two baffles 13 are arranged in parallel, and the gap between the two baffles 13 forms a guide channel for the sliding of the bearing seat a. At the same time, the side walls of the guide channel also position the two sides of the bearing seat a. In addition, the guide channel has a trumpet-shaped open structure on the side close to the flip pipe 11, which is used to guide the sliding of the bearing seat a into the guide channel. The side of the guide channel away from the flip pipe 11 is provided with a buffer block 15, which can block the outlet of the guide channel and buffer the impact of the sliding of the bearing seat a, thereby accurately transporting the bearing seat a to the loading station.

[0037] Furthermore, in order to prevent the boss a1 at the bottom of the bearing seat a from tilting during transportation after the bearing seat a is turned over, as shown in FIG. Figure 4 As shown, a slot 121 for accommodating boss a1 is provided on the surface of the loading platform 12 at the loading station. The length of the slot 121 is arranged along the length of the guide channel. This ensures that when the bearing seat a slides in the guide channel, its boss a1 always slides in the slot 121, further positioning the bearing seat a while ensuring the sliding stability of the bearing seat a.

[0038] In addition, if Figure 4 As shown, the baffle 13 in the present application is movably connected to the loading platform 12. Specifically, the baffle 13 is driven by the lifting cylinder 19 and can slide in the vertical direction to the bottom of the table of the loading platform 12. Therefore, when the bearing seat a on the loading station needs to be transferred to the pressing station of the pressing machine, the baffle 13 can slide down to the bottom of the table of the loading platform 12 without hindering the transfer process.

[0039] like Figure 3 As shown, the buffer block 15 is made of nylon and has good anti-collision and wear resistance, and an elastic buffer member 14 is provided on the side of the buffer block 15 away from the guide channel, which can achieve good buffering of the impact process.

[0040] On the basis of the above, if Figure 1 As shown, the gate mechanism 17 includes a gate cylinder 171 fixed on the flip pipe 11, and a gate plate 172 is fixed to the telescopic end of the gate cylinder 171. The gate plate 172 is driven by the gate cylinder 171 to extend into the inner cavity of the flip pipe 11, which can block the sliding of the bearing seat a. After the gate plate 172 moves out of the flip pipe 11, the bearing seat a is released, allowing the bearing seat a to slide again in the flip pipe 11 under low gravitational potential energy.

[0041] In order to prevent the bearing seat a from accumulating in large quantities in the turning pipe 11, Figure 1 and Figure 2 As shown, a feeder mechanism 18 is installed on the inverting pipe 11 near the processing platform belt line 20. This feeder mechanism 18 controls the time interval for the bearing seat a to enter the swirl section. Specifically, the feeder mechanism 18 includes a first feeder plate 181 and a second feeder plate 182 driven by a first feeder cylinder 183 and a second feeder cylinder 184, respectively. The first feeder plates 181 and the second feeder plates 182 are spaced apart and can be moved to separate the inner cavity of the inverting pipe 11. The spacing between the first feeder plate 181 and the second feeder plate 182 is adapted to the outer diameter of the bearing seat a. In the initial state, the first material dividing cylinder 183 drives the first material dividing plate 181 to move into the turning pipe 11 to block the transportation of all bearing seats a on the processing platform belt line 20 toward the turning pipe 11; thereafter, the second material dividing cylinder 184 drives the second material dividing plate 182 to move into the turning pipe 11, and the first material dividing cylinder 183 drives the first material dividing plate 181 to move out of the turning pipe 11. In this state, the bearing seat a located at the front side of the conveying path of the processing platform belt line 20 will move to the position aligned with the second material dividing cylinder 184. The two dividing plates 182 come into contact; thereafter, the first dividing cylinder 183 drives the first dividing plate 181 to move into the turning pipe 11 again, blocking the second bearing seat a located on the conveying path of the processing platform belt line 20. The second dividing cylinder 184 then drives the second dividing plate 182 to move outside the turning pipe 11 to release the bearing seat a located at the front side of the conveying path of the processing platform belt line 20, thereby enabling one bearing seat a to enter the turning pipe 11 separately, preventing a large number of bearing seats a from accumulating in the turning pipe 11. In actual implementation, the dividing mechanism 18 can also adopt other methods, such as the conventional robotic gripping method, which can realize the delivery of one bearing seat a into the turning pipe 11 at a time.

[0042] In addition, in order to facilitate the observation of the working state of the bearing seat a in the flip pipe 11, as shown in FIG. Figure 1 As shown, a plurality of viewing windows 111 are provided on the side wall of the flip pipe 11 .

[0043] On the basis of the above, if Figure 1 As shown, the first loading mechanism 10 is equipped with a clamping jaw loading module 16 to transfer the bearing seat A from the loading station to the press assembly station of the press assembly machine. Specifically, the clamping jaw loading module 16 includes a clamp that can move toward or away from each other, and also includes a multi-axis drive mechanism that realizes at least Z-axis and Y-axis motion.

[0044] To facilitate a further understanding of the structure of the present invention, the overall structure of the press is further described below in conjunction with other mechanisms in the press:

[0045] The main structure of the press machine includes a press-fitting rotary table 40, with a first loading mechanism 10, a second loading mechanism 30, a press-fitting mechanism 50, and a discharge mechanism 60 arranged in sequence along its circumference. The press-fitting stations of the press-fitting rotary table 40 are eccentrically arranged on its upper surface and can rotate about a vertical axis to the corresponding working area, thereby sequentially loading the bearing seat a, loading the bearing, press-fitting the bearing seat a and the bearing, and discharge the finished press-fitted product. Specifically:

[0046] 1. Press-fit rotary table 40

[0047] like Figure 8 As shown, preferably, the pressing stations of the pressing rotary table 40 are evenly distributed on the four upper end surfaces thereof in the circumferential direction, and the first loading mechanism 10, the second loading mechanism 30, the pressing mechanism 50 and the unloading mechanism 60 are evenly distributed on the sides of the pressing rotary table 40 in the circumferential direction; the pressing rotary table 40 rotates 90 degrees each time, so that after each rotation of the pressing rotary table 40, its four pressing stations can correspond to the first loading mechanism 10, the second loading mechanism 30, the pressing mechanism 50 and the unloading mechanism 60 respectively, thus realizing multi-station synchronous operation and improving the efficiency of the pressing machine. In addition, an inner groove matching the boss a1 is provided at the pressing station of the pressing rotary table 40, which can realize the accurate positioning of the bearing seat a during the pressing process, and a lower positioning member is provided at the bottom of the inner groove to position the bearing pressed into the bearing seat a, thereby ensuring the accuracy of the bearing being installed in the bearing seat a.

[0048] 2. First feeding mechanism 10

[0049] This has been described in detail in the previous article and will not be repeated here.

[0050] 3. Second feeding mechanism 30

[0051] like Figure 9As shown, the second loading mechanism 30 includes a vibrating screen plate 31 and a positioning loading module 32 for transferring the bearings on the vibrating screen plate 31 to the pressing station. The positioning loading module 32 is similar to the clamping loading module 16 of the first loading mechanism 10 and can transfer the bearings in the vibrating screen plate 31 to the pressing station.

[0052] 4. Pressing mechanism 50

[0053] The press-fitting mechanism 50 includes a pressing head that moves up and down in the vertical direction. The pressing head presses the bearing downward, thereby press-fitting the bearing to the inner side of the bearing seat a.

[0054] 5. Unloading mechanism 60

[0055] like Figure 10 As shown, the unloading mechanism 60 includes a detection platform 65 , a material distribution barrel 63 and a feeding module 61 .

[0056] Among them, the feeding module 61 is similar to the clamping feeding module 16 of the first feeding mechanism 10, and can transfer the finished products on the pressing station to the detection platform 65 for detection, and convey the products to the distribution barrel 63 after detection on the detection platform 65. A visual inspection module 62 is set on the detection platform 65 to detect whether the pressing of the finished products meets the standards. The distribution barrel 63 is an inverted Y-shaped structure, and the top of the inverted Y-shaped structure serves as the feeding port, and the two openings at the bottom serve as the discharging ports and point to the qualified product conveying line 66 and the unqualified product conveying line 67 respectively. A gate assembly 64 is installed on the distribution barrel 63 to switch the connection state between the feeding port and the two discharging ports. Of course, the unloading mechanism 60 also includes a central controller connected to the visual inspection module 62, the feeding module 61 and the gate assembly 64.

[0057] During operation, the feed module 61 first transfers the finished product to the inspection platform 65, where the visual inspection module 62 performs a quality inspection on the finished product and transmits the inspection results to the central controller. Afterwards, the feed module 61 transfers the inspected product to the feed port of the dispensing barrel 63. Furthermore, the central controller controls the operation of the gate assembly 64 based on the feedback of the inspection results. For example, if the product quality is qualified, the gate assembly 64 opens the discharge port corresponding to the qualified product conveyor line 66; if the product quality is unqualified, the gate assembly 64 controls the discharge port corresponding to the unqualified product conveyor line 67 to open, thereby allowing qualified finished products to be conveyed to the qualified product conveyor line 66 and unqualified products to be conveyed to the unqualified product conveyor line 67, thereby achieving quality classification of the finished products.

[0058] Of course, it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also encompasses the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and it is intended that all variations that fall within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

[0059] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
