Description

Technical Field

[0001] This invention belongs to the field of bearing manufacturing technology, specifically relating to a grinding apparatus for the outer ring of a tapered roller bearing. Background Technology

[0002] The outer ring of a tapered roller bearing is the core component. It is circular with a conical inner surface that adapts to the rolling elements. It supports the rolling elements, transmits complex loads, provides a stable rolling track, ensures smooth bearing rotation, and guarantees stable equipment operation. Unground surfaces may have defects such as burrs and cracks, which can aggravate wear and heat generation, leading to premature bearing failure. Grinding can reduce surface roughness, reduce friction and wear, eliminate stress concentration, improve fatigue resistance, and extend service life.

[0003] Currently, the tapered roller bearing outer ring grinding equipment on the market usually uses manual pushing to put the bearing outer rings one by one onto an iron rod or round rod to form a continuous string. Then, the operator manually places this string of bearing outer rings between the two working surfaces of the grinding device and pushes it manually to move it between the grinding devices, thereby achieving uniform grinding of the bearing outer ring surface.

[0004] However, this manual operation method has many drawbacks. First, operators need to spend a lot of time and energy to complete the stringing, placement, and pushing of the bearing outer rings, which is difficult to meet the needs of large-scale production. Second, when the bearing outer rings are connected in series, the end faces are in contact, which will cause friction between the end faces of the bearing outer rings, accelerate the wear of the bearing outer ring end faces, and thus affect their accuracy and service life. Furthermore, manual pushing may result in uneven pushing force, causing inconsistent grinding degree on the surface of the bearing outer rings, affecting the grinding quality, and making it impossible to ensure that each bearing outer ring can meet the precise processing requirements, thereby affecting the assembly accuracy and performance stability of the entire bearing. Summary of the Invention

[0005] The purpose of this invention is to provide a grinding device for the outer ring of tapered roller bearings, which can automatically complete the conveying of the bearing outer ring. During the conveying process, a separation structure is adopted to avoid direct contact friction between the end faces of the bearing outer ring, reduce end face wear, improve grinding quality, realize automated operation, improve production efficiency, and effectively meet the needs of large-scale production.

[0006] The specific technical solution adopted by this invention is as follows:

[0007] A grinding device for the outer ring of a tapered roller bearing includes a support box. A control box is fixedly installed on one side of the top of the support box. A polishing wheel is fixedly installed on the top of the support box and on the side near the control box. A conveying frame is installed on the side of the support box near the polishing wheel. A feed trough is fixedly connected to the top of one end of the conveying frame. The outer ring body of the bearing is slidably connected in the feed trough. A guide wheel is installed on the side of the support box away from the polishing wheel and near the conveying frame. A collection trough is fixedly connected to the bottom of one side of the support box.

[0008] The conveyor frame is equipped with a conveying assembly, which is used to continuously convey the bearing outer ring body to the area between the polishing wheel and the guide wheel for processing. This ensures that the bearing outer ring bodies are separated from each other while conveying multiple bearing outer ring bodies, achieving continuous and stable conveying. This avoids wear and tear on the operator's hands caused by manual pushing and also prevents the end faces of the bearing outer ring bodies from rubbing against each other during the grinding process.

[0009] The feeding trough is equipped with a feeding component, which is used to arrange the bearing outer ring body to be processed individually through the feeding trough, ensuring that only one bearing outer ring body enters the conveying component at a time. While the conveying component moves, the feeding component will drop a bearing outer ring body onto the conveying component, realizing a continuous and orderly feeding process of the bearing outer ring body, improving the automation level of the device, reducing manual intervention, and improving processing efficiency.

[0010] The conveyor frame is equipped with a pushing component. The pushing component is used to provide a reverse thrust to the outer ring body of the bearing while the conveyor component is conveying the outer ring body of the bearing. This allows the outer ring body of the bearing to be stably fitted onto the conveyor component, preventing it from sliding or shifting during the conveying process. This facilitates stable grinding of the outer ring body of the bearing when it enters the polishing wheel and guide wheel.

[0011] The guide wheel is equipped with a speed reduction assembly, which is used to cooperate between the guide wheel and the polishing wheel. When the outer ring body of the bearing enters the space between the polishing wheel and the guide wheel for grinding, the speed reduction assembly reduces the rotational speed of the guide wheel, thereby slowing down the rotational speed of the outer ring body of the bearing. This reduces the impact of excessive heat generated by high-speed operation on the outer ring body of the bearing.

[0012] Preferably, the conveying assembly includes a first gear rotatably connected to both sides of the inner wall of the conveying frame, a conveying chain rotatably connected to the surfaces of the two first gears, a plurality of support plates uniformly fixedly connected to the inner wall of the conveying chain, a push rod fixedly connected to one side of each support plate, a first rack fixedly installed on both sides of the bottom of each support plate, a first motor fixedly installed on one side of the conveying frame, and the output end of the first motor fixedly connected to the first gear.

[0013] Preferably, the feeding assembly includes a slide rail fixedly connected to one side of the feeding trough, a shaped rod slidably connected to the surface of the slide rail, and partition rods fixedly connected to both ends of the shaped rod and the side near the feeding trough. Strip-shaped insertion holes are provided on both sides of the feeding trough, and the partition rods are inserted into the strip-shaped insertion holes. A second rack is fixedly connected to the side of the shaped rod away from the slide rail, and a second gear is meshed with the bottom of the second rack. One end of the second gear is fixedly connected to one side of the feeding trough. Springs are fixedly connected to both sides of the conveying frame and the side near the feeding trough, and a connecting plate is fixedly connected to the top of the springs. A slide block is fixedly connected to the side of the feeding trough near the connecting plate, and the connecting plate is slidably connected within the slide block. A third rack is fixedly connected to one side of the top of the connecting plate, and one side of the third rack meshes with one side of the second gear. The bottom of the connecting plate is inserted into a support plate and located inside the conveying frame.

[0014] Preferably, the pushing assembly includes rectangular slots formed on both sides of the conveyor frame, with a pushing roller rotatably connected to the inner wall of each rectangular slot. Slotted holes are formed on both sides of the conveyor frame and at the bottom of the pushing rollers. A third gear is rotatably connected to each slotted hole. The top of the third gear is fixedly connected to the pushing roller. A fourth gear is meshed with one side of each third gear and is rotatably connected to the slotted hole. One side of the fourth gear meshes with a first rack.

[0015] Preferably, the deceleration assembly includes a reducer fixedly connected to one side of the guide wheel, a base plate fixedly connected to the bottom of the reducer, a base fixedly connected to the top of the support box near the base plate, a lead screw rotatably connected inside the base, the bottom of the base plate being threaded onto the surface of the lead screw, a feed handwheel rotatably connected to one side of the base, and a second motor fixedly installed on one side of the base plate with its output end fixedly connected to the guide wheel.

[0016] Preferably, the top and bottom of the support plate near the push rod are fixedly connected with abutments, and the support plate has an inverted L-shaped structure.

[0017] Preferably, the push rod has a frustum-shaped structure, and the outer ring body of the bearing is sleeved on the surface of the push rod.

[0018] Preferably, an output slide plate is fixedly connected to the bottom of the support box near the conveyor frame. The output slide plate is inclined, and the end of the output slide plate away from the support box extends into the inner cavity of the collection tank.

[0019] The technical effects achieved by this invention are as follows:

[0020] This invention discloses a grinding device for the outer ring of tapered roller bearings. Through the coordinated design of the conveying and feeding components, a control box drives a first motor to move a support plate on the conveyor chain, triggering the upward movement of a connecting plate. This, in turn, causes the irregularly shaped rod and partition rod, which mesh with a third rack, to move laterally within the feeding groove. The partition rod alternately intercepts the bearing outer ring body inside the feeding groove, facilitating the orderly feeding of individual bearing outer ring bodies without manual individual placement. The feeding rhythm matches the conveying rhythm, eliminating the need for machine downtime for feeding. The first motor drives a first gear to rotate the conveyor chain cyclically, moving the support plate and the pusher... The rod independently separates the bearing outer ring body, preventing multiple bearing outer ring body end faces from rubbing against each other during conveying and grinding, thus preventing end face damage. It also continuously conveys the bearing to the processing area, replacing manual pushing and avoiding hand wear. After processing, the bearing outer ring body automatically slides down to the collection tank via an inclined output slide. The device has a high degree of automation and can automatically complete the conveying of bearing outer rings. During the conveying process, the separation structure avoids direct contact friction between the bearing outer ring end faces, reducing end face wear, improving grinding quality, realizing automated operation, improving production efficiency, and effectively meeting the needs of large-scale production.

[0034] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to the accompanying drawings. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0035] like Figure 1 - Figure 11 As shown, a tapered roller bearing outer ring grinding device includes a support box 1, a control box fixedly installed on one side of the top of the support box 1, a polishing wheel 2 fixedly installed on the top of the support box 1 and the side near the control box, a conveyor frame 3 installed on the side of the support box 1 near the polishing wheel 2, a feed groove 4 fixedly connected to the top of one end of the conveyor frame 3, a bearing outer ring body 35 slidably connected in the feed groove 4, a guide wheel 5 installed on the side of the support box 1 away from the polishing wheel 2 and close to the conveyor frame 3, and a collection groove 6 fixedly connected to the bottom of one side of the support box 1.

[0036] The conveyor frame 3 is equipped with a conveying assembly, which is used to continuously convey the bearing outer ring body 35 to the polishing wheel 2 and the guide wheel 5 for processing. This ensures that the bearing outer ring bodies 35 are separated from each other while conveying multiple bearing outer ring bodies 35, so as to achieve continuous and stable conveying, avoid wear and tear on the operator's hands caused by manual pushing, and prevent the end faces of the bearing outer ring bodies 35 from rubbing against each other during the grinding process.

[0037] The feeding trough 4 is equipped with a feeding component, which is used to arrange the bearing outer ring body 35 to be processed individually through the feeding trough 4, ensuring that only one bearing outer ring body 35 enters the conveying component at a time. While the conveying component moves, the feeding component will drop a bearing outer ring body 35 onto the conveying component, realizing a continuous and orderly feeding process of the bearing outer ring body 35, improving the automation level of the device, reducing manual intervention, and improving processing efficiency.

[0038] The conveyor frame 3 is equipped with a pushing component. The pushing component is used to provide a reverse thrust to the bearing outer ring body 35 while the conveyor component is conveying the bearing outer ring body 35. This allows the bearing outer ring body 35 to be stably fitted onto the conveyor component, preventing it from sliding or shifting during the conveying process. This facilitates stable grinding of the bearing outer ring body 35 between the polishing wheel 2 and the guide wheel 5.

[0039] The guide wheel 5 is equipped with a speed reduction assembly, which is used to cooperate between the guide wheel 5 and the polishing wheel 2. When the bearing outer ring body 35 enters the space between the polishing wheel 2 and the guide wheel 5 for grinding, the speed reduction assembly reduces the rotation speed of the guide wheel 5, thereby slowing down the rotation speed of the bearing outer ring body 35. This can reduce the excessive heat generated by high-speed operation from affecting the bearing outer ring body 35.

[0040] The outer ring of a tapered roller bearing is an important component of the bearing. It is usually annular with a conical inner surface that mates with the rolling elements and cage. The outer ring of the tapered roller bearing mainly serves to support and transmit loads, ensuring the stable operation of the equipment. In order to improve the dimensional accuracy and surface quality of the outer ring, it is necessary to grind it appropriately to extend the service life of the bearing.

[0041] The control box is used to control the operation of the entire device. The top of the feeding trough 4 is connected to the existing automatic bearing outer ring push plate feeder. The automatic bearing outer ring push plate feeder is an automated material conveying equipment specially designed for the processing of bearing outer rings. Its core consists of a push plate mechanism, an aligning device, a guide rail, a drive system, a positioning component, and a control module. Its working logic is as follows: the aligning device sorts the messy bearing outer rings into a uniform posture, and then the push plate mechanism pushes them precisely into the feeding trough 4 along the guide rail. The entire process does not require manual intervention and can achieve continuous and orderly automated feeding. The bearing outer ring body 35 is neatly arranged and conveyed to the conveying component on the conveying frame 3 through the feeding trough 4. There is no need for manual placement. The conveying component then conveys the rings to the processing area. The entire process does not require much manual intervention. The control box is equipped with an intelligent control system. This system can accurately control the operating parameters of the conveying component, feeding component, pushing component, and deceleration component, and flexibly adjust the conveying speed, feeding rhythm, pushing force, and deceleration degree to ensure that each outer ring receives the most suitable processing.

[0042] The conveying assembly can precisely hold the outer ring body 35 of the bearing, preventing it from sliding or shifting during the conveying process. It cyclically and stably delivers the outer ring body 35 of the bearing to the processing area, improving processing efficiency and avoiding errors and safety hazards that may be caused by manual pushing.

[0043] The feeding assembly can trigger the mechanical structure to perform corresponding actions while the conveying assembly moves, ensuring that only one bearing outer ring body 35 enters the conveying assembly at a time, ensuring that the outer ring falls accurately into the conveying assembly, and independently separating the bearing outer ring body 35 to avoid the end faces of multiple bearing outer ring bodies 35 rubbing against each other during conveying and grinding.

[0044] While the conveying component moves, the pushing component works with the conveying component to provide a stable reverse thrust to the bearing outer ring body 35, ensuring that the bearing outer ring body 35 can be firmly fitted onto the conveying component and will not fall off or shift during subsequent grinding, making the grinding process more stable and reliable, and effectively improving the processing accuracy and finished product quality.

[0045] The speed reduction assembly can adjust the rotation speed of the guide wheel 5 in real time according to the actual needs of the processing, making the grinding of the bearing outer ring body 35 more precise and stable. At the same time, the speed reduction assembly can be moved away from or close to the conveyor frame 3, making it easier for staff to inspect or replace parts, shortening the equipment maintenance and repair time, and improving the overall efficiency of the equipment.

[0046] like Figure 3 and Figure 4As shown, the conveying assembly includes a first gear 7 rotatably connected to both sides of the inner wall of the conveying frame 3. A conveying chain 8 is rotatably connected to the surfaces of the two first gears 7. Multiple support plates 9 are uniformly fixedly connected to the inner wall of the conveying chain 8. A push rod 10 is fixedly connected to one side of each support plate 9. A first rack 11 is fixedly installed on both sides of the bottom of each support plate 9. A first motor 12 is fixedly installed on one side of the conveying frame 3, and the output end of the first motor 12 is fixedly connected to the first gear 7.

[0047] Specifically, the first motor 12 is driven by the control box, which in turn drives the first gear 7 to rotate. Since the two first gears 7 are connected by the conveyor chain 8, the rotation of the first gear 7 will drive the conveyor chain 8 to rotate cyclically, which in turn drives the support plate 9 on the conveyor chain 8 to move along with the rotation of the conveyor chain 8, so that multiple support plates 9 pass through the feeding position, the pushing position and the grinding position in sequence, and so on, to achieve efficient and continuous grinding processing.

[0048] The mutual rotation and grinding of multiple bearing outer ring bodies 35 end faces generates significant friction and heat, affecting the end face quality of the bearing outer ring bodies 35. Therefore, the design of the support plate 9 and push rod 10 is used to divide the multiple bearing outer ring bodies 35, allowing each bearing outer ring body 35 to be ground independently. The support plate 9 and push rod 10 provide stable support for the bearing outer ring bodies 35. The bearing outer ring bodies 35 are fitted onto the surface of the push rod 10, ensuring the smoothness of the movement of the bearing outer ring bodies 35 driven by the push rod 10, and avoiding the impact of shaking on the grinding effect. In the actual processing, the operator only needs to place the bearing outer ring body 35 to be processed in the feeding position and start the equipment through the control box. The entire grinding process can then be carried out automatically, continuously, and efficiently, improving production efficiency and processing quality.

[0049] like Figure 5 and Figure 6As shown, the feeding assembly includes a slide rail 13 fixedly connected to one side of the feeding trough 4. A shaped rod 14 is slidably connected to the surface of the slide rail 13. Partition rods 15 are fixedly connected to both ends of the shaped rod 14 and to the side closest to the feeding trough 4. Strip-shaped insertion holes 16 are provided on both sides of the feeding trough 4. The partition rods 15 are inserted into the strip-shaped insertion holes 16. A second rack 17 is fixedly connected to the side of the shaped rod 14 away from the slide rail 13. A second gear 18 is meshed with the bottom of the second rack 17. One end of the second gear 18 is fixedly connected to... A spring 19 is fixedly connected to one side of the feed trough 4 and both sides of the conveyor frame 3, and to the side closest to the feed trough 4. A plug plate 20 is fixedly connected to the top of the spring 19. A slide block 21 is fixedly connected to the side of the feed trough 4 near the plug plate 20. The plug plate 20 is slidably connected in the slide block 21. A third rack 22 is fixedly connected to one side of the top of the plug plate 20. One side of the third rack 22 is meshed with one side of the second gear 18. The bottom of the plug plate 20 is inserted into the support plate 9 and located inside the conveyor frame 3.

[0050] The control box drives the first motor 12 to rotate, which in turn drives the conveyor chain 8 to rotate. This causes the support plate 9 and push rod 10 to move simultaneously with the rotation of the conveyor chain 8, thereby pushing the bottom of one side of the plug plate 20 to move upward. The plug plate 20 moves vertically upward in the slide block 21, which in turn causes the second gear 18, which is meshed with the third rack 22 at the top of the plug plate 20, to rotate. The rotation of the second gear 18 causes the second rack 17, which is meshed with the top of the second gear 18, to move the shaped rod 14 laterally. This causes the two staggered partition rods 15 to move with the movement of the two ends of the shaped rod 14. The bottom partition rod 15 is pulled out of the feed trough 4 so that one bearing outer ring body 35 at the top of the partition rod 15 can fall onto the support plate 9 in the conveyor frame 3. At the same time, the top partition rod 15 enters the feed trough 4 to intercept other bearing outer ring bodies 35 and prevent them from falling. This ensures that only one bearing outer ring body 35 enters the support plate 9 at a time, achieving orderly conveying.

[0051] When the bottom of the plug plate 20 moves to the side of the next support plate 9, it is simultaneously affected by the tension of the spring 19, causing the plug plate 20 to be re-inserted into the next support plate 9. At the same time, the third rack 22 at the top of the plug plate 20 moves down, causing the second gear 18 to rotate in the opposite direction, which in turn causes the second rack 17 and the shaped rod 14 to move in the opposite direction. At this time, the bottom partition rod 15 that was originally pulled out re-enters the feed trough 4, while the partition rod 15 that was originally in the top of the feed trough 4 is pulled out of the feed trough 4. At this time, the bottommost of the other bearing outer ring bodies 35 that was originally intercepted continues to fall, and the bottom partition rod 15 intercepts it, ensuring that only one bearing outer ring body 35 enters the support plate 9 at a time. This cycle repeats. Through the drive control of the first motor 12 by the control box, the bearing outer ring body 35 is conveyed in an orderly and continuous manner within the device.

[0052] The linkage between the feeding and conveying components eliminates the need to stop the machine for feeding, ensuring that the feeding rhythm matches the conveying rhythm. This allows the device to continuously and orderly convey materials, improving the automation level of the device, reducing manual intervention, and increasing processing efficiency.

[0053] like Figure 8 and Figure 9 As shown, the pushing assembly includes rectangular grooves 23 on both sides of the conveyor frame 3. Each rectangular groove 23 has a pushing roller 24 rotatably connected to its inner wall. The conveyor frame 3 has strip holes 25 on both sides and at the bottom of the pushing rollers 24. Each strip hole 25 has a third gear 26 rotatably connected to its inner wall. The top of the third gear 26 is fixedly connected to the pushing roller 24. Each third gear 26 has a fourth gear 27 meshing with its side and the fourth gear 27 is rotatably connected to its side hole 25. One side of the fourth gear 27 meshes with the first rack 11.

[0054] Specifically, when the control box drives the conveyor chain 8 to rotate, it drives multiple support plates 9 to move, which in turn drives the first rack 11 on the support plate 9 to move, causing the fourth gear 27 meshing on both sides to rotate in the strip hole 25. The rotation of the fourth gear 27 then drives the third gear 26 meshing with it to rotate in the opposite direction in the strip hole 25. Since the top of the third gear 26 is fixedly connected to the push roller 24, the reverse rotation of the third gear 26 will drive the push roller 24 to rotate on the inner wall of the rectangular groove 23. During the rotation, the push roller 24 can push the bearing outer ring body 35 on the moving support plate 9 in the opposite direction, so that the bearing outer ring body 35 passing through the push device area can be accurately fitted onto the push rod 10, so that the bearing outer ring body 35 after being fitted can be transported between the polishing wheel 2 and the guide wheel 5 for grinding, preventing the bearing outer ring body 35 from shifting during the grinding process and effectively improving the processing quality.

[0055] like Figure 11 As shown, the deceleration assembly includes a reducer 28 fixedly connected to one side of the guide wheel 5, a base plate 29 fixedly connected to the bottom of the reducer 28, a base 30 fixedly connected to the top of the support box 1 near the base plate 29, a lead screw 31 rotatably connected inside the base 30, the bottom of the base plate 29 is threaded onto the surface of the lead screw 31, a feed handwheel 32 rotatably connected to one side of the base 30, and a second motor 33 fixedly installed on one side of the base plate 29, with the output end of the second motor 33 fixedly connected to the guide wheel 5.

[0056] The feed handwheel 32 is manually rotated to drive the lead screw 31 to rotate within the base 30. Since the bottom thread of the base plate 29 is fitted onto the surface of the lead screw 31, the rotation of the lead screw 31 will cause the base plate 29 to move on the surface of the lead screw 31. The movement of the base plate 29 will then drive the reducer 28 to move, and the movement of the reducer 28 will in turn drive the guide wheel 5 to move. At the same time, the output end of the second motor 33 is fixedly connected to the guide wheel 5, which can change the rotation speed of the guide wheel 5 and reduce the rotation speed of the guide wheel 5. This will slow down the rotation speed of the bearing outer ring body 35, thereby reducing the impact of excessive heat generated by high-speed operation on the bearing outer ring body 35.

[0057] like Figure 6 As shown, the top and bottom of the support plate 9 near the push rod 10 are fixedly connected with abutment blocks 34, and the support plate 9 has an inverted L-shaped structure.

[0058] Specifically, the abutment 34 fixedly connected to the support plate 9 is used to prevent friction between the bearing outer ring body 35 and the support plate 9. The abutment 34 is made of wear-resistant material, and its surface is specially treated to be smooth and have high hardness. During the operation of the device, when the bearing outer ring body 35 rotates, the abutment 34 can effectively isolate the bearing outer ring body 35 from the support plate 9, avoiding direct contact between the two, thereby greatly reducing wear and heat caused by friction. Its reverse L-shaped structure design forms a tight and reasonable fit with the adjacent push rod 10, ensuring that the positions of each component are relatively fixed and reducing shaking and displacement during operation.

[0059] like Figure 7 As shown, the push rod 10 has a frustum-shaped structure, and the bearing outer ring body 35 is sleeved on the surface of the push rod 10.

[0060] The frustum-shaped design of the push rod 10 makes the contact area between it and the inner surface of the bearing outer ring body 35 more reasonable. The frustum-shaped structure of the push rod 10 can also provide a certain guiding effect for the bearing outer ring body 35, ensuring the stability of the bearing outer ring body 35 during rotation and preventing it from deviating. In addition, the frustum-shaped structure design makes the bottom of the bearing outer ring body 35 move upward away from the support plate 9, so that the surface of the bearing outer ring body 35 does not come into contact with other structures during the rotational grinding process, ensuring the smoothness of the grinding of the bearing outer ring body 35, reducing the additional friction and resistance that may be generated due to contact with other structures, and helping to improve the working efficiency and stability of the entire device.

[0061] like Figure 11 As shown, an output slide plate 36 is fixedly connected to the bottom of the support box 1 near the conveyor frame 3. The output slide plate 36 is inclined, and the end of the output slide plate 36 away from the support box 1 extends into the inner cavity of the collection tank 6.

[0062] Specifically, the inclined design of the output slide plate 36 can guide the finished bearing outer ring body 35 to slide into the inner cavity of the collection tank 6 for collection, so as to facilitate its subsequent unified processing, improve the automation level of the production process, reduce the manual intervention links, reduce labor intensity, and improve product quality and production efficiency.

[0063] The working principle of this invention is as follows: First, by manually rotating the feed handwheel 32, the guide wheel 5 on the base plate 29 is driven to move closer to one side of the conveyor frame 3. Then, the control box drives the first motor 12 to rotate the first gear 7, which in turn drives the conveyor chain 8 to rotate cyclically, causing the support plate 9 and push rod 10 on the conveyor chain 8 to move. When the support plate 9 moves, it pushes the insertion plate 20 to move upward in the slide 21. The upward movement of the third rack 22 drives the second gear 18 to rotate, so that the second rack 17, which meshes with the second gear 18, drives the irregular rod 14 to move laterally, causing the spacer 15 to open and close alternately in the strip-shaped insertion hole 16, realizing the bearing outer ring body. 35 bearing rings fall onto the support plate 9 in an orderly manner; secondly, when the support plate 9 moves, the first racks 11 on both sides mesh with the fourth gear 27 to rotate, driving the third gear 26 and the push roller 24 to rotate, providing a reverse thrust to the bearing outer ring body 35, ensuring that the bearing outer ring body 35 is stably fitted on the push rod 10. While the push rod 10 conveys the bearing outer ring body 35, the second motor 33 adjusts the guide wheel 5 to slow down, and cooperates with the polishing wheel 2 to complete the grinding of the bearing outer ring body 35; finally, the processed bearing outer ring body 35 slides down the output slide plate 36 into the collection groove 6 for collection, thereby completing the separation and continuous automated grinding of the bearing outer ring body 35.
