Description

Technical Field

[0001] This application relates to the field of polishing machines, and more particularly to a feeding mechanism for a polishing machine. Background Technology

[0002] A polishing machine is a mechanical device used to polish the surface of objects. It removes dirt, oxide layers, and blemishes from the surface of objects through rotation and friction, making the surface smooth and shiny. Polishing machines are widely used in the surface treatment of materials such as metals, plastics, and stone, and common applications include automotive repair, furniture manufacturing, and architectural decoration.

[0003] A bearing is a component that supports a shaft, guiding its rotation and also allowing it to withstand free rotation. Bearings can be divided into rolling bearings and sliding bearings, with rolling bearings being the most common. Rolling bearings need to withstand large loads during use, so they are usually polished during the manufacturing process to give them good surface strength, thereby reducing friction during use and ensuring that they do not undergo excessive deformation or damage.

[0004] The existing bearing conveying device for polishing machines includes a recess and a mounting base fixedly installed on the bottom wall of the recess. A lifting scissor fork device is fixedly installed on the top of the mounting base. A lifting frame is connected to the top of the lifting scissor fork device by nuts and bolts. A support seat is fixed to the top of the lifting frame by countersunk screws. A material conveying platform is movably connected to the top of the support seat by a pin. The device also includes an angle adjustment component disposed between the lifting frame and the material conveying platform. When the angle adjustment component is activated, the conveying bottle rotates relative to the support seat. Through the arrangement of the lifting device, the angle adjustment component, and the material conveying platform, the material conveying platform can be adjusted to a certain height and angle as needed, so that the bearing tilts downward from the hopper and slides down onto the material platform.

[0005] When the above-mentioned equipment is used to transport bearings to the polishing machine, as the bearings fall from the hopper downwards, due to the large opening of the hopper, a large number of bearings fall downwards onto the conveying platform at the same time. When a large number of bearings slide down together onto the conveying platform, it becomes difficult for the polishing machine to polish the bearings, thus affecting the polishing effect of the bearings. Summary of the Invention

[0006] To reduce the possibility of feeding a large number of bearings to the polishing machine body at the same time, this application provides a feeding mechanism for a polishing machine.

[0007] The feeding mechanism of the polishing machine provided in this application adopts the following technical solution:

[0008] A feeding mechanism for a polishing machine includes a frame, on which a feeding device is mounted. The feeding device has a conveying track for connecting to and feeding the shot blasting machine body. The feeding device includes a disc, a frame, a support plate, and a first driving component. The disc is rotatably mounted on the frame. The first driving component is mounted on the frame and is drively connected to the disc. The frame is mounted on the frame and extends circumferentially along the outer edge of the disc. The frame is located above the disc and has a discharge port for feeding a single bearing. The support plate is mounted on the frame and suspended from it. The support plate is located on the side of the disc away from the discharge port. The vertical height between the support plate and the upper surface of the disc is greater than the height of a single bearing but less than the combined height of two bearings. The support plate has a guide component for guiding the bearing to the edge of the disc when the disc rotates. One end of the conveying track is mounted on the frame and communicates with the discharge port, and the other end is connected to the shot blasting machine body.

[0009] By adopting the above technical solution, when feeding bearings, the bearings to be polished are placed in batches in the conveying space between the disc and the frame. The first driving component drives the disc to rotate on the frame. Under the action of centrifugal force, the bearings on the disc gradually approach the inner wall of the frame. When the bearings pass the support plate, the bearings at higher positions fall down, so that the bottom of each bearing contacts the upper surface of the disc. The guide component accelerates the speed at which the bearings approach the inner wall of the frame as the disc rotates. When the bearings rotate to the discharge port, the bearings are conveyed downwards one by one along the discharge port and the conveying track, reducing the possibility of too many bearings reaching the polishing machine body at the same time, which would affect the polishing effect of the bearings.

[0010] Optionally, the guiding assembly includes a guide plate, and a vertically downward extending connecting rod is provided on the support plate. One end of the guide plate is rotatably mounted on the connecting rod, and the other end extends toward the inner wall of the frame. The guide plate is located between the support plate and the discharge port, and the end of the guide plate away from the connecting rod forms a flow port for the bearing with the frame.

[0011] By adopting the above technical solution, when the guide assembly guides the bearing to the inner wall of the frame, the bearing contacts and is squeezed by the guide plate during the rotation of the disc. During the squeezing process, the bearing slides along the extension direction of the guide plate, making the bearing closer to the inner wall of the frame, making it easier for the bearing to approach the discharge port, thereby improving the feeding speed of the bearing.

[0012] Optionally, the guide assembly further includes an elastic element, one end of which is disposed on the support plate and the other end of which is disposed on the end of the guide plate away from the connecting rod. When the guide plate and the bearing are pressed against each other, the elastic element changes elastically. An adjustment assembly is provided between the elastic element and the support plate to adjust the connection position between the elastic element and the support plate.

[0013] By adopting the above technical solution, when the outer diameter of the bearing to be loaded on the disc is large, the adjusting component drives one end of the elastic element to slide on the support plate, so that the guide plate rotates on the connecting rod. The flow opening between the guide plate and the inner wall of the frame increases, making it easier for the bearing to pass through the flow opening, reducing the squeezing force between the bearing and the guide plate, thereby reducing the possibility of bearing wear.

[0014] Optionally, the adjustment assembly includes an adjustment block and a positioning element. A sliding groove extending along the length of the support plate is provided on the support plate. The adjustment block is slidably disposed in the sliding groove. The positioning element is disposed between the adjustment block and the support plate. One end of the elastic element is rotatably disposed on the guide plate through a connecting block, and the other end is disposed on the adjustment block.

[0015] By adopting the above technical solution, when the bearings to be fed on the disc are of different sizes and the size of the flow port needs to be adjusted, the positioning component loosens its fixing effect on the adjusting block, and the adjusting block slides in the sliding groove. After the size of the flow port changes, the positioning component fixes the adjusting block on the sliding groove, which facilitates the adjustment of the size of the flow port and reduces the bearing blockage at the flow port. During the adjustment process, the spring rotates relative to the connecting block, reducing the possibility of the spring bending between the support plate and the guide plate.

[0016] Optionally, a material guiding device is provided between the frame and the conveying track. The material guiding device includes a material guiding channel, a limiting component, and a pushing component. One end of the material guiding channel is located on the frame and communicates with the discharge port, and the other end is connected to the conveying track. The limiting component is located between the material guiding channel and the frame and is used to adjust the actual size of the channel at the material guiding channel. The pushing component is located on the frame. When a bearing larger than the actual size of the material guiding channel is blocked at the discharge port, the pushing component pushes the bearing blocking the discharge port into the disc.

[0017] The polishing time varies depending on the size of the bearing. Therefore, the polishing machine needs to be adjusted to ensure that the polished bearing meets the corresponding production requirements.

[0018] When bearings of different sizes need to be placed between a disc and a frame, workers usually need to monitor the loading of bearings on the disc after placing bearings of the same size between the disc and the frame. They need to ensure that the loading of bearings of the same size is almost completed before placing bearings of another size on the disc. Therefore, workers need to pay attention to the loading of bearings on the disc at all times, which increases the workload of the workers.

[0019] By adopting the above technical solution, when bearings of different sizes need to be fed, bearings of various specifications are placed between the disc and the frame at the same time. The limiting component limits the actual conveying channel of the guide channel from small to large in sequence, so that the bearings are conveyed downwards in order of their size from small to large. During the conveying of smaller sizes, when a larger bearing is blocked in the guide channel, the pushing component pushes the larger bearing into the disc, reducing the possibility of bearing blockage in the guide channel. This allows bearings of different sizes to be placed in the disc and the frame at the same time, reducing the workload of workers when placing bearings one by one.

[0020] Optionally, the limiting component includes a limiting plate and a second driving member. The first end of the limiting plate is rotatably mounted on the frame, and the tail end is located in the material guide channel and extends along the width direction of the material guide channel. The second driving member is mounted on the frame and is connected to the limiting plate in a transmission manner. The tail end of the limiting plate moves closer to or away from the center of the material guide channel under the drive of the second driving member.

[0021] By adopting the above technical solution, when the limiting plate blocks the bearing, the second driving component drives the limiting plate to rotate on the frame, so that the tail end of the limiting plate rotates into the material guide channel. When bearings of different sizes are conveyed downward from the tail end of the limiting plate and the material guide channel, the second driving component drives the limiting plate away from the material guide channel. The outer diameter of the bearings is conveyed downward in sequence from small to large, so that the size of the bearings conveyed downward is consistent when the position of the limiting plate remains unchanged, thereby reducing the adjustment frequency of the polishing machine body.

[0022] Optionally, a detection component is provided between the frame and the housing. The detection component includes a pressure sensor and a controller. The pressure sensor is mounted on a limiting plate, and the controller is mounted on the frame. The pressure sensor is electrically connected to the controller, the second drive component is electrically connected to the controller, and the controller is electrically connected to the push component. When the pressure value of the pressure sensor exceeds the preset value in the controller, the controller activates the push component to push the bearing into the disc.

[0023] By adopting the above technical solution, during the downward conveying of bearings with smaller outer diameters, when a larger bearing gets stuck between the limiting plate and the guide channel, the pressure sensor experiences a greater squeezing force. When the squeezing force detected by the controller exceeds the preset value in the controller, the controller controls the pushing component to push the larger bearing into the disc, reducing the possibility of the larger bearing getting stuck between the limiting plate and the guide channel during the conveying of the smaller bearing. In addition, when the controller detects that the squeezing force detected by the pressure sensor exceeds the preset value in the controller for a relatively long period of time, the controller controls the second driving component to start. The second driving component moves the tail end of the limiting plate away from the center of the guide channel, thereby increasing the unloading space between the limiting plate and the guide channel.

[0024] Optionally, the pushing assembly includes a pushing rod and a third driving member. The third driving member is disposed on the frame, and the pushing rod is disposed between the third driving member and the frame. The third driving member drives the pushing rod to slide on the frame and push the bearing. The third driving member is electrically connected to the controller.

[0025] By adopting the above technical solution, the controller controls the third driving component to start, which drives the push rod to slide on the guide channel, thereby pushing the bearing blocked between the limit plate and the guide channel into the disc, reducing the possibility of large bearings being blocked in the guide channel and affecting the bearing feeding efficiency.

[0026] Optionally, a baffle assembly is provided between the frame and the conveying track to reduce bearing accumulation at the feed inlet of the shot blasting machine body. The baffle assembly includes a fourth driving component and two baffle plates. The two baffle plates are slidably disposed between the frame and the conveying track and are distributed on the conveying track along the width direction of the conveying track. The fourth driving component is disposed on the frame and drives the two baffle plates to move closer to or further away from each other.

[0027] By adopting the above technical solution, when the conveying track continuously conveys the bearing downwards, the fourth drive component drives the two baffles to move closer to each other, causing the bearing to stop being conveyed. After the bearing has been polished for a period of time, the fourth drive component drives the two baffles to move away from each other, and the bearing resumes conveying, reducing the possibility of bearings accumulating at the feed inlet of the polishing machine body.

[0028] Optionally, grooves are provided on the surfaces of both baffles facing the material guide channel. The two grooves fit against the outer wall of the bearing. A rubber layer is provided on the inner wall of the grooves. The rubber layer extends along the bearing conveying direction to the surface of the baffles facing away from the material guide channel.

[0029] By adopting the above technical solution, the two baffles are brought close to each other, so that when the bearing stops conveying, the groove on the baffle contacts the outer wall of the bearing. The rubber layer in the groove reduces the collision and friction between the baffle and the bearing, thereby reducing the possibility of bearing wear.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Place the bearing to be polished in the conveying space between the disc and the frame. The first drive unit drives the disc and the bearing to rotate and convey, so that the bearing is conveyed down one by one along the feeding port on the frame, reducing the possibility of a large number of bearings being conveyed to the polishing machine body at the same time and affecting the polishing effect of the bearing.

[0032] 2. When the bearings are conveyed downwards in the material guide channel, the limiting component will convey the bearings downwards in sequence from small to large, so that the bearings conveyed downwards are of the same size within a certain period of time, reducing the frequency of adjustment of the polishing machine body.

[0033] 3. When a large bearing becomes blocked between the limiting plate and the guide channel, the controller activates the third drive component. The third drive component drives the push rod to slide into the disc, pushing the blocked bearing into the disc and reducing the possibility of blockage in the guide channel.

[0041] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0042] This application discloses a feeding mechanism for a polishing machine. (Refer to...) Figure 1 It includes a frame 1, on which a feeding device 2 is installed for feeding bearings one by one in sequence, and a conveying track 3 is installed between the feeding device 2 and the frame 1 for connecting to the feed inlet of the polishing machine body.

[0043] Reference Figure 1 and Figure 2 The feeding device 2 includes a disc 21, a frame 22, a support plate 23, and a first driving component 24. The disc 21 is rotatably mounted on the frame 1 and flush with the upper surface of the frame 1. The first driving component 24 includes a first driving motor, which is mounted on the frame 1 and located below the disc 21. The output shaft of the first driving motor is coaxially connected to the disc 21. When feeding bearings, if... Figure 2 The first drive motor drives the disc 21 to rotate clockwise.

[0044] The frame 22 is mounted on the frame 1 and located above the disc 21. The frame 22 is located on the outer edge of the disc 21 and extends circumferentially along the disc 21. The outer diameter of the frame 22 is larger than the outer diameter of the disc 21. The frame 22 surrounds the disc 21, forming a bearing conveying space between the frame 22 and the disc 21. A discharge port 232 is provided on the frame 22, extending tangentially along the frame 22. The discharge port 232 is only large enough for a single bearing to pass through. A support plate 23 is mounted on the frame 22. The vertical height between the support plate 23 and the upper surface of the disc 21 is greater than that of a single bearing. The height of the bearing is lower than the stacked height of the two bearings. The support plate 23 is located on the side of the center of the disc 21 facing away from the feed port 232. When feeding the bearing, the bearing is placed in the conveying space between the disc 21 and the frame 22. The first drive motor is started, and the first drive motor drives the disc 21 to rotate. The bearing rotates with the disc 21. The support plate 23 blocks the bearings stacked in the vertical direction, so that the bearings located at the high position fall and directly contact the upper surface of the disc 21. When the bearing rotates to the feed port 232, the bearings are conveyed downward from the feed port 232 one by one.

[0045] Reference Figure 1 and Figure 2 A vertically downward extending connecting rod 231 is installed on the support plate 23. The bottom end of the connecting rod 231 does not contact the upper surface of the disk 21. A guide assembly 4 is installed between the connecting rod 231 and the support plate 23 to guide the bearing to the edge of the disk 21.

[0046] The guide assembly 4 includes a guide plate 41 and an elastic element 42. One end of the guide plate 41 is rotatably mounted on the connecting rod 231, and the other end extends horizontally toward the inner wall of the frame 22. The guide plate 41 and the support plate 23 are arranged intersectingly, and the guide plate 41 is located between the support plate 23 and the discharge port 232. The end of the guide plate 41 away from the connecting rod 231 forms a flow port 411 through which the bearing passes between it and the inner wall of the frame 22. The elastic element 42 includes a spring. A connecting block 43 is mounted on the end of the guide plate 41 away from the connecting rod 231. The connecting block 43 is located on the upper surface of the guide plate 41. One end of the spring is rotatably mounted on the connecting block 43. The pivot between the spring and the connecting block 43 extends in the vertical direction. The other end of the spring is mounted on the support plate 23 through the adjusting assembly 6.

[0047] Reference Figure 2 and Figure 3 The adjusting assembly 6 includes an adjusting block 61 and a positioning element 62. A sliding groove 233 extending along the length of the support plate 23 is provided on the support plate 23. The sliding groove 233 is inverted trapezoidal. The adjusting block 61 is slidably installed in the sliding groove 233. The positioning element 62 includes a positioning bolt, which is threaded onto the adjusting block 61. The bottom end of the positioning bolt abuts against the bottom wall of the sliding groove 233. When the outer diameter of the bearing in the disc 21 is large, and the flow opening 411 between the guide plate 41 and the frame 22 is smaller than the outer diameter of the bearing, the positioning bolt is tightened, causing the adjusting block 61 to slide in the sliding groove 233. The connecting block 43 rotates on the guide plate 41, reducing the possibility of spring bending. The guide plate 41 rotates on the connecting rod 231 as the spring moves, thereby adjusting the size of the flow port 411 and reducing the possibility of the bearing getting stuck at the flow port 411. When the disc 21 drives the bearing to rotate and transport, the bearing slides along the length of the guide plate 41 to the flow port 411, so that the bearing is close to the inner wall of the frame 22. When the bearing is transported at the flow port 411, the spring extends and retracts appropriately, and the guide plate 41 rotates appropriately on the connecting rod 231, reducing the possibility of mutual wear between the end of the guide plate 41 and the outer wall of the bearing.

[0048] Reference Figure 1 and Figure 2 A material guiding device 5 is installed between the material outlet 232 of the frame 22 and the conveying track 3. The material guiding device 5 includes a material guiding channel 51, a limiting component 54, a detection component 53 and a pushing component 52. The material guiding channel 51 is installed at the material outlet 232 of the frame 22 and extends downward at an inclination away from the frame 22.

[0049] Reference Figure 2 and Figure 4The limiting component 54 includes a limiting plate 542 and a second driving component 541. The first end of the limiting plate 542 is rotatably mounted on the frame 22, and the tail end is located in the material guide channel 51 and extends along the bearing conveying direction. The second driving component 541 includes a second driving motor, which is mounted on the frame 1. The second driving motor drives the limiting plate 542 to rotate on the frame 22. When the limiting plate 542 rotates, it rotates to the center of the material guide channel 51, thereby adjusting the size of the discharge port 232. This allows bearings of the same size to be conveyed downwards and fed in a concentrated period of time, reducing the frequency of adjustment of the polishing machine due to the different polishing conditions of bearings of different sizes.

[0050] Reference Figure 2 and Figure 4 The pushing assembly 52 includes a third driving component 521 and a pushing rod 522. The third driving component 521 includes a servo cylinder, which is mounted on the frame 1 and located on the side of the guide channel 51 opposite to the limiting plate 542. One end of the pushing rod 522 is mounted on the electric push rod of the servo cylinder, and the other end extends along the servo cylinder toward the disk 21. An abutment block 523 is provided on the end of the pushing rod 522 away from the servo cylinder. When the abutment block 523 is not pushed out, it is located on the side of the limiting plate 542 away from the disk 21. The pushing rod 522 and the abutment block 522... Driven by the servo cylinder, the servo cylinder slides on the side wall of the guide channel 51. The end of the abutment block 523 facing away from the servo cylinder has a fitting groove 524 that abuts against the outer wall of the bearing. When the bearing abuts between the limiting piece 542 and the guide channel 51, the servo cylinder drives the push rod 522 to slide on the frame 22, so that the abutment block 523 abuts against the bearing, and the fitting groove 524 on the abutment block 523 fits against the bearing, thereby pushing the bearing into the disc 21, reducing the possibility of the bearing getting stuck in the guide channel 51 and affecting the bearing feeding effect.

[0051] The detection component 53 includes a pressure sensor 532 and a controller 531. The pressure sensor 532 is mounted on the limiting plate 542 and is located at one end of the limiting plate 542 near the center of the guide channel 51. The controller 531 is mounted on the frame 1. The pressure sensor 532 is electrically connected to the controller 531, and the servo cylinder is electrically connected to the controller 531. When the squeezing force detected by the pressure sensor 532 exceeds the preset value in the controller 531, the controller 531 controls the servo cylinder to start, driving the push rod 522 and the abutment block 523 to slide on the frame 22, thereby pushing the bearing blocked between the limiting plate 542 and the frame 22 into the disc 21, thereby continuously feeding bearings of different sizes in time intervals and reducing the number of times the polishing machine body is adjusted.

[0052] A monitoring component 55 for monitoring the bearing feeding status in the material guide channel 51 is installed on the material guide channel 51. The monitoring component 55 includes an infrared receiver and an infrared transmitter 551. The infrared receiver and infrared transmitter 551 are both installed on the inner wall of the material guide channel 51 and distributed along the width direction of the material guide channel 51. The infrared receiver and infrared transmitter 551 are both located on the side of the limiting plate 542 facing away from the disk 21. The infrared receiver is electrically connected to the controller 531, and the second drive motor is electrically connected to the controller 531. When the infrared receiver can continuously receive the infrared emitted by the infrared transmitter 551 for a certain period of time, the controller 531 controls the second drive motor to start, driving the limiting plate 542 to rotate, so that the tail end of the limiting plate 542 rotates away from the center of the material guide channel 51, thereby increasing the feeding space between the limiting plate 542 and the material guide channel 51, so that the bearing with a larger outer diameter is conveyed downward and fed.

[0053] Reference Figure 1 and Figure 5 A baffle assembly 7 is installed between the frame 1 and the conveying track 3 to reduce the accumulation of bearings at the feed inlet of the polishing machine body. The baffle assembly 7 includes a fourth drive member 71 and two baffle plates 72. Two slide grooves 31 are provided on the conveying track 3. The two slide grooves 31 are distributed along the width direction of the conveying track 3 and both slide grooves 31 extend along the width direction of the conveying track 3. The two baffle plates 72 correspond one-to-one with the two slide grooves 31 and are slidably connected. The fourth drive member 71 drives the two baffle plates 72 to slide in the slide grooves 31. The upper end of the baffle plate 72 extends to the center of the conveying track 3, so that the continuously conveyed bearings are intermittently conveyed, reducing the possibility of bearings being continuously conveyed to the polishing machine body and accumulating.

[0054] Reference Figure 5 and Figure 6 The baffle plate 72 has a groove 721 on the side facing the guide channel 51 that fits against the outer wall of the bearing. A rubber layer 722 is installed on the surface of the groove 721, covering the inner wall of the groove 721. The rubber layer 722 extends along the bearing conveying direction to the surface of the baffle plate 72 on the side facing away from the guide channel 51, thereby covering the ends of the two baffle plates 72 facing each other, reducing the possibility of wear on the bearing surface caused by the baffle plate 72.

[0055] Reference Figure 6The fourth driving component 71 includes a fourth driving motor 711 and a driving screw 712. The driving screw 712 is rotatably mounted on the frame 1 and extends along the width direction of the conveying track 3. The driving screw 712 is a bidirectional threaded rod. The two baffle plates 72 correspond one-to-one with the two ends of the driving screw 712 and are threadedly connected. The fourth driving motor 711 is mounted on the frame 1, and the output shaft of the fourth driving motor 711 is coaxially connected to the driving screw 712. When the fourth driving motor 711 is started, the driving screw 712 is driven to rotate on the frame 1, thereby causing the two baffle plates 72 to slide on the conveying track 3 and move closer to each other, thereby blocking the bearing and reducing the possibility of the bearing accumulating near the polishing machine body.

[0056] The implementation principle of the feeding mechanism of a polishing machine according to an embodiment of this application is as follows:

[0057] When feeding the polishing machine, the bearing to be fed is placed in the conveying space between the disc 21 and the frame 22. The first drive motor drives the disc 21 to rotate, and the bearing on the disc 21 rotates with the disc 21. The support plate 23 blocks and drops the bearings piled up in the vertical direction, so that the bearings are all in contact with the upper surface of the disc 21.

[0058] The guide plate 41 moves the bearing that rotates with the disc 21 toward the inner wall of the frame 22, so that the bearing is close to the inner wall of the frame 22, which facilitates the bearing to be conveyed downward from the discharge port 232 and fed. The discharge port 232 only allows a single bearing to be conveyed downward, so that the bearings are conveyed downward one by one and fed, reducing the possibility of multiple bearings being conveyed to polishing at the same time and affecting the polishing effect of the bearing.

[0059] When the spring causes the bearing to contact the guide plate 41, the guide plate 41 rotates on the connecting rod 231 and swings back and forth within a certain range, reducing the possibility of wear between the guide plate 41 and the bearing. At the same time, it reduces the influence of the guide plate 41's guiding function on the rotation of the bearing and the disc 21.

[0060] When the outer diameter of the bearing is large and the flow port 411 between the guide plate 41 and the frame 22 is not suitable for bearing transportation, the positioning bolt is turned and the adjusting block 61 is slid in the sliding groove 233 to increase the flow port 411 between the guide plate 41 and the frame 22, which facilitates bearing guidance and transportation.

[0061] The second drive motor drives the limit plate 542 to rotate on the frame 22. The size of the discharge port 232 can be adjusted by the second drive motor and the limit plate 542, which facilitates the continuous conveying of bearings of the same size within a period of time and reduces the frequency of equipment adjustment during the polishing process of the bearing.

[0062] When the larger bearing is squeezed between the end of the limiting plate 542, and the squeezing force detected by the pressure sensor 532 exceeds the preset value in the controller 531, the controller 531 controls the servo cylinder to start. The servo cylinder drives the push rod 522 and the abutment block 523 to push the bearing at the limiting plate 542, so that the bearing with the larger outer diameter slides into the disc 21, so that the size of the bearings continuously conveyed for a period of time is consistent, reducing the frequency of polishing machine adjustment.

[0063] When the abutting block 523 abuts against the bearing, the fitting groove 524 on the abutting block 523 contacts the outer wall of the bearing, increasing the contact area between the abutting block 523 and the bearing and reducing the wear between the bearing and the abutting block 523.

[0064] When the bearing is conveyed along the guide channel 51 and the conveying track 3, the fourth drive motor 711 drives the drive screw 712 to rotate. The two baffles 72 move closer or further apart between the frame 1 and the conveying track 3, thereby blocking or releasing the bearing, so that the bearing on the conveying track 3 is intermittently conveyed to the polishing machine, reducing the possibility of bearings accumulating at the feed inlet of the polishing machine.

[0065] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
