TECHNICAL FIELD

[0001] The application relates to the technical field of bearing assembly, in particular to a bearing automatic assembly machine. BACKGROUND

[0002] The bearing automatic assembly machine is a highly automated mechanical equipment specially used for the assembly process of bearings. The machine is designed to improve production efficiency, reduce manual operation, ensure assembly precision, and improve overall product quality. The working principle of the machine is that the feeding system transports each component to the assembly station, the positioning and clamping mechanism ensures the accurate positioning of the components, the assembly mechanism assembles each component together according to the predetermined program and parameters, the detection and feedback system monitors the key parameters in real time to ensure the stability and consistency of the assembly quality, and the control system controls and adjusts the entire process to realize efficient and accurate assembly.

[0003] During the final assembly process of bearings, a certain amount of lubricating grease needs to be injected into the bearings to reduce friction during rotation. In the existing bearing assembly process, the lubricating grease is added to the inside of the bearing through a spray head. During the lubricating process, the bearing needs to be turned over to add an appropriate amount of lubricating grease to both sides. Since the lubricating grease has a certain flowability, and the flowability increases with the increase of temperature, during the turning over and subsequent conveying process of the bearing, the added grease may be thrown out or flow out, causing the conveying table to be contaminated with lubricating grease. In addition, the lower end of the bearing is easy to slip when contacting the lubricating grease during the conveying process to the next process, resulting in deviation between the final position of the bearing and the predetermined position, affecting the assembly precision of the bearing. Therefore, the bearing automatic assembly machine is proposed. SUMMARY

[0004] The purpose of the present application is to provide a bearing automatic assembly machine to solve the problems raised in the background.

[0005] To achieve the above purpose, the present application provides the following technical scheme: a bearing automatic assembly machine, comprising a conveying table, a feeding device, an assembling mechanism, a riveting device, two cleaning devices, a measuring device, an oiling bin and a detection device fixedly installed on the conveying table, two oil injection devices fixedly installed in the oiling bin, an oil injection nozzle slidably installed on each oil injection device, two fixed seats fixedly installed in the oiling bin, an electric shaft rotatably installed on each fixed seat, two clamping plates for clamping bearings provided on each electric shaft, two cover pressing devices for pressing covers on both sides of the bearing fixedly installed in the oiling bin, and an oil distribution device for uniformly distributing the lubricating grease in the bearing.

[0006] A first cylinder is fixedly installed on the fuel filling bin. A sliding plate is slidably installed at the output end of the first cylinder. A plurality of limiting clips for conveying bearings are fixedly installed on the sliding plate. A wedge block is fixedly installed at the lower end of the sliding plate. A wedge plate matched with the wedge block is slidably installed in the fuel filling bin, and the length of the wedge plate is greater than that of the wedge block. A plurality of telescopic columns are fixedly installed between the lower end of the wedge plate and the inner wall of the fuel filling bin. A plurality of limiting strips for limiting the bearings are fixedly installed at the upper end of the wedge plate.

[0007] Preferably, a third cylinder is fixedly installed in the fuel filling bin. A fixed disk is fixedly installed at the output end of the third cylinder. A pushing member is fixedly installed at the upper end of the fixed disk. A supporting member is slidably installed on the pushing member. Elastic rods are fixedly installed between both sides of the supporting member and the inner wall of the fuel filling bin. A magnetic strip is fixedly installed at the lower end of the supporting member. A magnetic plate magnetically attracted to the magnetic strip is slidably installed in the fixed disk. A plurality of second springs are fixedly connected between the magnetic plate and the inner wall of the fixed disk. A wedge member matched with the end of the magnetic plate is slidably installed in the fuel filling bin. An elastic column is fixedly connected between the wedge member and the inner wall of the fuel filling bin. A scraping strip for scraping the bearings off the conveying path is fixedly connected to the wedge member.

[0008] Preferably, limiting rods are fixedly installed on both sides of the magnetic plate. A guiding groove for limiting the limiting rods is arranged inside the fuel filling bin, and the guiding groove is designed in a "return" shape.

[0009] Preferably, a magnetic rod is fixedly installed at the lower end of the sliding plate. A circular groove for limiting the magnetic rod is arranged in the fuel filling bin. Magnetic blocks magnetically attracted to the magnetic rod are fixedly installed on the inner wall of the initial end and at the diagonal of the initial end of the circular groove.

[0010] Preferably, a plurality of telescopic rods for拨动 the balls inside the bearings are fixedly installed on each oil injection device. A plurality of elastic strips are fixedly installed on each telescopic rod. A plurality of positioning holes for limiting the elastic strips are arranged on each oil injection nozzle, and the positioning holes correspond to the elastic strips one by one.

[0011] Preferably, the lower end of each telescopic rod is located below the oil injection nozzle, and the lower end of the telescopic rod is arranged in an arc shape. The elastic force of the telescopic rod is less than the pulling force required for the elastic strip to deform.

[0012] Preferably, two sliding grooves are symmetrically arranged on each electric shaft. A guiding block is slidably installed in each sliding groove. Each guiding block is fixedly connected to the corresponding clamping plate, and a first spring is fixedly connected between the guiding block and the inner wall of the sliding groove. A limiting groove corresponding to the sliding groove is arranged on each fixed seat, and the limiting groove is located above the electric shaft. A second cylinder for pushing the clamping plate is fixedly installed on the fixed seat.

[0013] Preferably, a plurality of cleaning rollers for cleaning the bearing conveying path are rotatably mounted on the sliding plate, and a gear is fixedly mounted on each cleaning roller. A rack that meshes with the gear is fixedly mounted in the oil filling tank, and the rack is located on the movement trajectory of the cleaning roller.

[0014] Preferably, the magnetic attraction force of the magnetic strip to the magnetic plate is greater than the elastic force of the second spring.

[0015] Preferably, the upper end of each of the limiting bars is configured as a wedge shape to facilitate the pushing of the bearing.

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

[0017] 1. This invention utilizes a first cylinder to push a limiting card toward the bearing. The magnetic rod moves vertically along the straight groove at the initial end of the loop groove. After the first cylinder extends, the magnetic rod is attracted by the magnetic block at the diagonal end of the loop groove and moves laterally. The limiting card moves the bearing to the next process. At the same time, the wedge block and the wedge plate cooperate to make the wedge plate move the limiting strip downward. The first cylinder retracts and drives the magnetic rod to move vertically along another straight groove of the loop groove. The limiting card retracts and no longer limits the bearing. The limiting strip is extended upward by the elastic force of the telescopic column to limit the bearing again, so that the bearing is accurately positioned in the predetermined position, improving the accuracy of the bearing processing.

[0018] 2. This invention utilizes an oil injection nozzle to drive a telescopic rod downwards. The telescopic rod first contacts the balls inside the bearing, causing the balls to deviate from the oil outlet of the oil injection nozzle. This prevents the oil injection nozzle from directly spraying lubricating grease onto the balls, reducing the likelihood of lubricating grease adhering to the oil outlet due to contact between the oil outlet and the balls. Furthermore, the lubricating grease is sprayed between two adjacent balls, located deeper within the bearing, making it less likely to flow out during subsequent rotation and movement.

[0019] 3. This invention utilizes the weight of the bearing to press the support downwards. If the lubricating grease in the bearing does not flow out or the amount flowing out is within a reasonable error, the weight of the bearing will cause the magnetic strip to align with or be about to align with the magnetic plate. The magnetic strip will generate sufficient magnetic attraction to the magnetic plate, causing the magnetic plate to be in a retracted state. When the weight of the lubricating grease in the bearing is insufficient, the magnetic attraction generated by the magnetic strip on the magnetic plate is insufficient. The magnetic plate will extend to a corresponding length according to the magnitude of the magnetic attraction of the magnetic strip on the magnetic plate. The third cylinder extends and drives the magnetic plate to move upwards. If the magnetic strip generates sufficient magnetic attraction to the magnetic plate, the magnetic plate will move laterally along the bottom of the guide groove to the left vertical groove during the upward process, and finally retract to the initial end of the guide groove. If the magnetic strip generates insufficient magnetic attraction to the magnetic plate, the magnetic plate will move laterally along the bottom of the guide groove to the right vertical groove during the upward process. The end of the magnetic plate will contact the inclined surface of the wedge-shaped piece. The wedge-shaped piece drives the scraper to scrape the bearings on the support, screening bearings with insufficient internal lubricating grease. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-14This invention provides a technical solution: an automatic bearing assembly machine, including a conveyor table 1, a feeding device 2, an assembly mechanism 3, a riveting device 4, two cleaning devices 5, a measuring device 6, a lubrication tank 7, and a detection device 49 fixedly installed on the conveyor table 1 (the feeding device 2, assembly mechanism 3, riveting device 4, cleaning device 5, measuring device 6, and detection device 49 are all existing known structures, so this invention will not elaborate further). Two capping devices 34 for covering both sides of the bearing and a grease-smoothing device 35 for evenly distributing lubricating grease inside the bearing are fixed inside the lubrication tank 7 (the capping devices 34 and the grease-smoothing device 35 are also existing known structures, so this invention will not elaborate further). The lubrication tank 7 is fixed with... A first cylinder 8 is installed, and a sliding plate 9 is slidably installed at the output end of the first cylinder 8. Several limit clips 10 for conveying bearings are fixedly installed on the sliding plate 9. A magnetic rod 15 is fixedly installed at the lower end of the sliding plate 9. A loop groove 16 for limiting the magnetic rod 15 is provided in the oil filling tank 7. Magnetic blocks 17 that are magnetically attracted to the magnetic rod 15 are fixedly installed on the inner wall of the initial end of the loop groove 16 and on the inner wall at the diagonal corners of the initial end. A wedge block 11 is fixedly installed at the lower end of the sliding plate 9. A wedge plate 12 that cooperates with the wedge block 11 is slidably installed in the oil filling tank 7, and the length of the wedge plate 12 is greater than that of the wedge block 11. Several telescopic columns 14 are fixedly installed between the lower end of the wedge plate 12 and the inner wall of the oil filling tank 7. Several telescopic columns 14 for conveying bearings are fixedly installed at the upper end of the wedge plate 12. The limiting strips 13 that limit the bearing are designed with a wedge shape at the top to facilitate the pushing of the bearing. In the initial state, the first cylinder 8 is in the retracted state, and the wedge block 11 does not limit the wedge plate 12. The limiting strips 13 and the wedge plate 12 are pushed upward by the elastic force of the telescopic column 14. The limiting strips 13 extend upward to limit the bearing. When the first cylinder 8 extends, it pushes the sliding plate 9 and the limiting clip 10 toward the bearing. The magnetic rod 15 moves vertically along the straight groove at the initial end of the loop groove 16. At the same time, the inclined surface of the wedge block 11 cooperates with the inclined surface of the wedge plate 12, causing the wedge plate 12 to drive the limiting strips 13 downward and compress the telescopic column 14. After the first cylinder 8 has extended completely, the magnetic rod 15 will move to the corner of the loop groove 16. Then, attracted by the magnetic block 17 at the diagonal of the initial end of the spiral groove 16, the bearing moves laterally, causing the sliding plate 9 to slide at the output end of the first cylinder 8. Simultaneously, the limit card 10 moves the bearing to the next process position. Since the length of the wedge plate 12 is greater than that of the wedge block 11, the wedge plate 12 is always limited by the wedge block 11. Then, the first cylinder 8 retracts, causing the magnetic rod 15 to move vertically along another straight groove of the spiral groove 16. The limit card 10 retracts and no longer limits the bearing. At the same time, the wedge block 11 no longer limits the wedge plate 12. The limit bar 13 extends upwards under the elastic force of the telescopic column 14 to limit the bearing again, ensuring the bearing is precisely positioned in the predetermined location. This improves the accuracy of the bearing processing. After the first cylinder 8 retracts...The magnetic rod 15 will be attracted again by the magnetic block 17 at the initial end of the spiral groove 16, causing it to move laterally and reset. At this time, all the bearings in the oil tank 7 are transported to the next corresponding process.

[0037] Two oil injection devices 21 are fixedly installed inside the refueling tank 7. Each oil injection device 21 has an oil injection nozzle 22 slidably mounted on it. Each oil injection device 21 has several telescopic rods 23 fixedly mounted on it for actuating the internal balls of the bearing. Each telescopic rod 23 has several elastic strips 24 fixedly mounted on it. Each oil injection nozzle 22 is provided with several positioning holes 25 for limiting the elastic strips 24. The positioning holes 25 correspond one-to-one with the elastic strips 24. Each telescopic rod 2... The lower ends of the telescopic rods 23 are all located at the lower end of the oil injection nozzle 22, and the lower ends of the telescopic rods 23 are all arc-shaped. The elastic force of the telescopic rods 23 is less than the pulling force required for the elastic strip 24 to deform. After the first cylinder 8 retracts, the oil injection device 21 will be activated, causing the oil injection nozzle 22 to move downward. Since the initial elastic force of the telescopic rods 23 is less than the pulling force required for the elastic strip 24 to deform, the oil injection nozzle 22 will drive the lower end of the telescopic rods 23 to move downward. Since the lower ends of the telescopic rods 23 are all located at the lower end of the oil injection nozzle 22, the lower ends of the telescopic rods 23 are all arc-shaped. At the lower end, the telescopic rod 23 will first contact the balls inside the bearing, and the lower end of the telescopic rod 23 is arc-shaped. As the telescopic rod 23 moves downward, the balls of the bearing will rotate, causing the balls to deviate from the oil outlet of the oil injection nozzle 22. This prevents the oil injection nozzle 22 from directly spraying lubricating grease onto the balls, reducing the possibility of lubricating grease adhering to the oil outlet due to contact between the oil outlet and the balls. The lubricating grease is sprayed between two adjacent balls, located deeper in the bearing. During subsequent flipping and movement, the lubricating grease is less likely to flow out. After the ball position is adjusted, the telescopic rod 23 will stop moving. As the oil injection nozzle 22 descends, the elastic strip 24 will deform and disengage from the positioning hole 25. Then, the elastic force of the telescopic rod 23 will drive it to move upward and reset, without affecting the oil output of the oil injection nozzle 22. After the oil injection nozzle 22 completes the oil injection, it will retract upward, and the elastic strip 24 will deform again and re-engage into the positioning hole 25.

[0038] Two fixed seats 32 are fixedly installed inside the refueling tank 7. An electric shaft 27 is rotatably mounted on each fixed seat 32. Each electric shaft 27 has two clamping plates 28 for gripping the bearing. Two symmetrical sliding grooves 31 are arranged on each electric shaft 27. A guide block 29 is slidably installed in each sliding groove 31. Each guide block 29 is fixedly connected to the corresponding clamping plate 28 and a first spring 30 is fixedly connected to the inner wall of the sliding groove 31. Each fixed seat 32 has a limiting groove 33 corresponding to the sliding groove 31, located above the electric shaft 27. A second cylinder 26 for pushing the clamping plates 28 is fixedly installed on the fixed seat 32. Initially, both sliding grooves 31 are vertical. The guide block 29 in the lower sliding groove 31 drives the lower clamping plate 28 to be positioned on the bearing conveying trajectory, while the upper sliding groove 31... When groove 31 aligns with limiting groove 33, guide block 29 will drive the upper clamping plate 28 to move upward into limiting groove 33. After the first cylinder 8 retracts, the second cylinder 26 will also extend, pushing the upper clamping plate 28 downward along limiting groove 33, and causing the guide block 29 corresponding to the upper clamping plate 28 to also enter the corresponding slide groove 31. At this time, the two clamping plates 28 will clamp the bearing. Then the second cylinder 26 will retract, and at the same time the electric shaft 27 will rotate 180 degrees. The guide block 29 is limited by the fixed seat 32 and cannot extend out of the slide groove 31. The electric shaft 27 will drive the clamping plate 28 and the bearing to flip. The lower clamping plate 28 will flip to the upper side, and the lower slide groove 31 will correspond to the limiting groove 33. At this time, the upper clamping plate 28 will be pushed upward by the elastic force of the first spring 30 and will no longer limit the bearing. The bearing has completed the flipping.

[0039] A third cylinder 36 is fixedly installed inside the refueling compartment 7. A fixed plate 37 is fixedly installed at the output end of the third cylinder 36. A pusher 38 is fixedly installed on the upper end of the fixed plate 37. A support 39 is slidably installed on the pusher 38. Elastic rods 40 are fixedly installed on both sides of the support 39 between them and the inner wall of the refueling compartment 7. A magnetic strip 41 is fixedly installed at the lower end of the support 39. A magnetic plate 42 that is magnetically attracted to the magnetic strip 41 is slidably installed inside the fixed plate 37. Several second springs 43 are fixedly connected between the magnetic plate 42 and the inner wall of the fixed plate 37. The magnetic attraction force of the magnetic strip 41 on the magnetic plate 42 is greater than the elastic force of the second springs 43. A wedge-shaped part 46 that mates with the end of the magnetic plate 42 is slidably installed inside the refueling compartment 7. An elastic column 48 is fixedly connected between the wedge-shaped part 46 and the inner wall of the refueling compartment 7. A scraper 47 for scraping the bearing along the conveying path is fixedly connected to component 46. Limiting rods 44 are fixedly installed on both sides of the magnetic plate 42. The oil filling chamber 7 is provided with a guide groove 45 for limiting the limiting rods 44. The guide groove 45 is designed in the shape of a "U". In the initial state, the third cylinder 36 is in the extended state, pushing the fixed plate 37, the pushing component 38 and the supporting component 39 to move upward to support the bearing. At this time, because the magnetic attraction force of the magnetic strip 41 on the magnetic plate 42 is greater than the elastic force of the second spring 43, the magnetic plate 42 retracts into the fixed plate 37. The limiting rod 44 is located at the initial end of the upper left corner of the guide groove 45. The magnetic plate 42 does not limit the wedge 46. The wedge 46 is pushed by the elastic force of the elastic column 48, so that the scraper 47 is not on the bearing conveying path. The bearing's conveying is not affected. After the first cylinder 8 retracts, the third cylinder 36 will also retract. The fixed plate 37 no longer limits the support 39, and the pusher 38 no longer supports the bearing. The bearing's weight will press the support 39 downward and compress the elastic rod 40. When the fixed plate 37 moves downward, it will drive the magnetic plate 42 and the limiting rod 44 downward. The limiting rod 44 will move vertically downward along the initial end of the guide groove 45. If the lubricating grease in the bearing has not flowed out or the amount of flow is within a reasonable error, the weight of the bearing will cause the support 39 to drive the magnetic strip 41 downward, and make the magnetic strip 41 aligned with or about to be aligned with the magnetic plate 42. The magnetic strip 41 will generate sufficient magnetic attraction force on the magnetic plate 42, making the magnetic plate 42 in a retracted state. When the lubricating oil in the bearing... When the grease weight is insufficient, the magnetic attraction force generated by the magnetic strip 41 on the magnetic plate 42 is insufficient. The magnetic plate 42 will extend to a corresponding length according to the magnitude of the magnetic attraction force of the magnetic strip 41 on the magnetic plate 42. When the magnetic plate 42 extends, the limiting rod 44 will move laterally along the bottom of the guide groove 45. Then, the third cylinder 36 will extend, driving the fixed plate 37 and the magnetic plate 42 to move upward. If the magnetic strip 41 generates sufficient magnetic attraction force on the magnetic plate 42, the magnetic plate 42 will move laterally along the bottom of the guide groove 45 to the left vertical groove during the upward process, and finally retract to the initial end of the guide groove 45. At this time, the end of the magnetic plate 42 does not contact the wedge 46. After the fixed plate 37 has finished rising, the pushing member 38 and the supporting member 39 will provide support for the bearing again. The magnetic strip 41 will align with the magnetic plate 42 and generate sufficient magnetic attraction force.The magnetic plate 42 is kept in a retracted state. If the magnetic attraction force generated by the magnetic strip 41 on the magnetic plate 42 is insufficient, the magnetic plate 42 will move laterally along the bottom of the guide groove 45 to the right vertical groove during its ascent. At this time, the end of the magnetic plate 42 will contact the inclined surface of the wedge 46. During the ascent of the magnetic plate 42, the wedge 46 will drive the scraper 47 to scrape the bearing on the support 39, causing it to leave the bearing conveying track. The unqualified bearing will not be conveyed to the next process. After the third cylinder 36 has extended, the magnetic strip 41 will align with the magnetic plate 42 and generate sufficient magnetic attraction force, causing the magnetic plate 42 to return to its initial state along the upper transverse groove of the guide groove 45. The wedge 46 is driven by the elastic force of the elastic column 48 to reset the scraper 47, effectively screening bearings with insufficient internal lubrication.

[0040] Several cleaning rollers 18 for cleaning the bearing conveying path are rotatably mounted on the sliding plate 9. Each cleaning roller 18 is fixedly mounted with a gear 19. A rack 20 that meshes with the gear 19 is fixedly mounted in the oil filling tank 7. The rack 20 is located on the movement trajectory of the cleaning roller 18. When the first cylinder 8 extends, it will drive the cleaning roller 18 to move onto the bearing conveying trajectory and make the gear 19 mesh with the rack 20. When the sliding plate 9 slides, the meshing of the gear 19 and the rack 20 will cause the gear 19 to drive the cleaning roller 18 to move and rotate at the same time, cleaning the bearing conveying trajectory, reducing the impact of lubricating grease on bearing conveying, and keeping the bearing conveying trajectory clean. When the first cylinder 8 retracts, the cleaning roller 18 will also retract, and the gear 19 will no longer mesh with the rack 20. When the sliding plate 9 resets, it will also drive the cleaning roller 18 and the gear 19 to reset.

[0041] Specifically, firstly, the inner and outer rings of the bearing are conveyed one by one to the conveyor table 1 by the feeding device 2. Then, the first cleaning device 5 performs preliminary demagnetization and cleaning. Next, the inner ring, outer ring, and balls of the bearing are assembled by the assembly mechanism 3. Then, the balls are evenly distributed by the riveting device 4, and the balls are limited by the riveting shims. After that, the bearing undergoes secondary demagnetization and cleaning by the second cleaning device 5. Then, the inner and outer diameters and clearance of the bearing are measured by the measuring device 6. Then, the bearing enters the lubrication tank 7 to inject lubricating grease and is capped. Finally, the bearing passes through the detection device 49 to detect noise and other factors during use. Finally, qualified products are output. After the bearing enters the lubrication tank 7, when the first cylinder 8 extends, it pushes the sliding plate 9. As the limit card 10 moves toward the bearing, the magnetic rod 15 moves vertically along the initial straight groove of the loop groove 16. Simultaneously, the inclined surface of the wedge block 11 engages with the inclined surface of the wedge plate 12, causing the wedge plate 12 to drive the limit strip 13 downwards and compress the telescopic column 14. After the first cylinder 8 extends, the magnetic rod 15 moves to the corner of the loop groove 16, and then moves laterally due to the attraction of the magnetic block 17 at the diagonal corner of the initial end of the loop groove 16. This causes the sliding plate 9 to slide at the output end of the first cylinder 8. Simultaneously, the limit card 10 drives the bearing to the next process position. Then, the first cylinder 8 retracts, causing the magnetic rod 15 to move vertically along another straight groove of the loop groove 16. The limit card 10 retracts and no longer limits the bearing, while the wedge block 11 no longer limits the wedge plate. 12. Limiting bar 13 will extend upward under the elastic force of telescopic column 14 to limit the bearing again. After the first cylinder 8 retracts, magnetic rod 15 will be attracted by the initial end magnetic block 17 of the loop groove 16 to move laterally and reset. After the first cylinder 8 retracts, the oil injection device 21 will be activated, causing the oil injection nozzle 22 to move downward. Since the elastic force of telescopic rod 23 is less than the pulling force required for the elastic bar 24 to deform, the oil injection nozzle 22 will drive the lower end of telescopic rod 23 to move downward. Since the lower end of telescopic rod 23 is located at the lower end of oil injection nozzle 22, telescopic rod 23 will first contact the balls in the bearing. The lower end of telescopic rod 23 is arc-shaped. As telescopic rod 23 moves downward, the balls in the bearing will rotate, causing the balls to deviate from the oil outlet of oil injection nozzle 22, avoiding... The lubricating nozzle 22 directly sprays lubricating grease onto the ball bearings. After the ball bearing position is adjusted, the telescopic rod 23 stops moving. As the lubricating nozzle 22 descends, the elastic strip 24 deforms and disengages from the positioning hole 25. Then, the elastic force of the telescopic rod 23 itself drives it to move upward and reset, without affecting the oil output of the lubricating nozzle 22. After the lubricating nozzle 22 completes the lubrication, it retracts upward, and the elastic strip 24 deforms again and re-engages into the positioning hole 25. After the first cylinder 8 retracts, the second cylinder 26 extends, pushing the upper clamping plate 28 downward along the limiting groove 33, and causing the guide block 29 corresponding to the upper clamping plate 28 to enter the corresponding sliding groove 31. At this time, the two clamping plates 28 clamp the bearing, and then the second cylinder 26 retracts.Simultaneously, the electric shaft 27 will rotate 180 degrees, and the guide block 29 will be limited by the fixed seat 32, preventing it from extending out of the slide groove 31. The electric shaft 27 will drive the clamping plate 28 and the bearing to flip, with the lower clamping plate 28 flipping to the upper position. The lower slide groove 31 will then correspond to the limiting groove 33. At this time, the upper clamping plate 28 will be pushed upward by the elastic force of the first spring 30, no longer limiting the bearing. The bearing completes its flip, and after the first cylinder 8 retracts, the third cylinder 36 will retract. The fixed plate 37 will no longer limit the support member 39, and the pushing member 38 will no longer support the bearing. The weight of the bearing will press the support member 39 downward and compress the elastic rod 40. When 37 moves downward, it will drive the magnetic plate 42 and the limiting rod 44 downward. The limiting rod 44 will move vertically downward along the initial end of the guide groove 45. If the lubricating grease in the bearing does not flow out or the amount of flowout is within a reasonable error, the weight of the bearing will cause the support 39 to drive the magnetic strip 41 downward, and make the magnetic strip 41 aligned with or about to be aligned with the magnetic plate 42. The magnetic strip 41 will generate sufficient magnetic attraction force on the magnetic plate 42, so that the magnetic plate 42 is in a retracted state. When the weight of the lubricating grease in the bearing is insufficient, the magnetic attraction force generated by the magnetic strip 41 on the magnetic plate 42 is insufficient. The magnetic plate 42 will extend to a corresponding length according to the magnitude of the magnetic attraction force of the magnetic strip 41 on the magnetic plate 42. When the magnetic plate 42 extends, the limiting rod 44 will move vertically downward along the initial end of the guide groove 45. Positioning rod 44 will move laterally along the bottom of guide groove 45, and then the third cylinder 36 will extend, driving the fixed plate 37 and magnetic plate 42 to move upward. If the magnetic strip 41 generates sufficient magnetic attraction force on the magnetic plate 42, the magnetic plate 42 will move laterally along the bottom of guide groove 45 to the left vertical groove during its ascent, and finally retract to the initial end of guide groove 45. At this time, the end of the magnetic plate 42 will not contact the wedge 46. After the fixed plate 37 has finished rising, the pushing member 38 and the supporting member 39 will provide support to the bearing again. The magnetic strip 41 will align with the magnetic plate 42 and generate sufficient magnetic attraction force to keep the magnetic plate 42 in the retracted state. If the magnetic attraction force generated by the magnetic strip 41 on the magnetic plate 42 is insufficient, the magnetic plate 42 will not move upward. During the ascent of plate 42, it moves laterally along the bottom of guide groove 45 to the right vertical groove. At this time, the end of magnetic plate 42 will contact the inclined surface of wedge 46. During the ascent of magnetic plate 42, wedge 46 will drive scraper 47 to scrape the bearing on support 39, causing it to leave the bearing conveying track. The unqualified bearing will not be conveyed to the next process. After the third cylinder 36 extends, magnetic strip 41 will align with magnetic plate 42 and generate sufficient magnetic attraction, causing magnetic plate 42 to return to its initial state along the upper transverse groove of guide groove 45. Wedge 46 is driven by the elastic force of elastic column 48 to reset scraper 47, effectively screening bearings with insufficient internal lubrication.
