Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, and in particular to a sealed bearing inner ring processing device. Background Art

[0002] A bearing is a component that supports a mechanical rotating body, reduces the friction coefficient during its movement, and ensures its rotation accuracy. Bearings generally have an inner ring and an outer ring. The outer wall of the inner ring has a raceway, while the inner wall of the outer ring has a raceway.

[0003] When installing the balls of a ball bearing, it is generally necessary to grind the inner ring of the bearing. However, some existing factories and workshops generally directly grind the inner ring of the bearing manually with sandpaper, which has low grinding efficiency and is relatively inconvenient. In addition, the general function of the bearing is to support the shaft. When in use, a connector is basically installed on the inner wall of the inner ring of the bearing, and then installed on the mechanical structure shaft through the connector. During installation, it is also necessary to grind the inner wall of the inner ring of the bearing. Some existing factories and workshops generally grind it manually, and since the raceway of the ball bearing is basically an arc-shaped surface, it is difficult to grind the raceway during grinding, which is relatively inconvenient. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a sealed bearing inner ring processing device, by placing the bearing inner ring on a moving mechanism, starting the moving mechanism, moving the bearing inner ring between the two grinding mechanisms and being located inside the variable mechanism, starting the variable mechanism to fix it against the inner wall of the bearing inner ring, and then starting the adjusting mechanism to drive the two grinding mechanisms to grind the outer wall of the bearing inner ring through the moving mechanism, and then starting the variable mechanism to drive the two grinding mechanisms to clamp the bearing inner ring, and then starting the adjusting mechanism to drive the variable mechanism to rotate through the moving mechanism to grind the inner wall of the bearing inner ring, so that the inner and outer walls of the bearing inner ring can be automatically polished.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A sealed bearing inner ring processing device comprises a barrel body, a U-shaped frame is arranged above the barrel body, and one end of two arms of the U-shaped frame are fixedly connected to the outer wall of the barrel body, a changing mechanism is arranged between the two arms of the U-shaped frame, and two grinding mechanisms are arranged on the changing mechanism, an adjusting mechanism is arranged inside the barrel body, and a moving mechanism is arranged above the adjusting mechanism;

[0007] The grinding mechanism includes a rectangular frame, and sliding grooves are formed on the opposite inner side walls of the rectangular frame. A U-shaped frame is slidably connected between the two sliding grooves. A rotating roller is rotatably connected between the two arms of the U-shaped frame, and an abrasive belt is fixedly wound around the outer side wall of the rotating roller. A triangular plate is arranged between the two arms of the U-shaped frame, and one edge of the triangular plate abuts against the abrasive belt. A threaded hole is formed on one side of the U-shaped frame, and a screw rod is screwed into the threaded hole. One end of the screw rod is rotatably connected to one side of the triangular plate. Rectangular sponges are fixedly connected to both sides of one side of the rectangular frame. Rectangular blocks are provided on the opposite sides of the two U-shaped frames. The U-shaped frame slides in the adjacent sliding grooves through the rectangular blocks and cannot rotate. By rotating the rotating rollers on the two grinding mechanisms, the thickness of the abrasive belt can be adjusted. Then, the screw rod is rotated to press the triangular plate against the abrasive belt to make it stop rotating, so as to fix the thickness of the abrasive belt on the rotating roller. And by rotating the screw rod, the rectangular blocks on the U-shaped frame abut against the side walls of the sliding grooves, making it difficult for the U-shaped frame to slide. By adhering items such as grinding plates on the sponges to grind the outer side wall of the inner ring of the bearing. Then, the two rectangular frames are clamped on the inner ring of the bearing. Then, the two U-shaped frames are slid so that the abrasive belts on the two rotating rollers are stuck on the raceways on the outer side wall of the inner ring of the bearing. One side of the two U-shaped frames is an arc surface, so that the grinding plates on the two sponges can contact the outer side wall of the inner ring of the bearing and perform grinding, enabling the user to adjust according to different specifications of the inner ring of the bearing, so that the outer side wall and the raceway of the inner ring of the bearing are fully ground. And through the cooperation of the moving mechanism, the adjusting mechanism and the changing mechanism, the user does not need to manually grind the inner ring of the bearing. Since the abrasive belt is formed by winding, the winding gap will be compressed when being squeezed, and when not being compressed, the abrasive belt will naturally spread out, increasing the diameter of the roller formed by its winding.

[0008] Furthermore, the change mechanism includes a first electric push rod, and one end of the first electric push rod is fixedly connected to the center of the inner top surface of the U-shaped frame. A connecting plate and a connecting block are arranged below the first electric push rod. The movable end of the first electric push rod penetrates through the center of the top surface of the connecting plate and is fixedly connected to the center of the top surface of the connecting block. The center of the top surface of the connecting plate is rotatably connected to the outer side wall of the movable end of the first electric push rod. Support plates are rotatably connected to both opposite sides of the connecting plate, and support rods are rotatably connected to both ends of the connecting block. Frames are arranged below both support plates, and sliding plates are slidably connected to the interiors of both frames. One adjacent end of both sliding plates is rotatably connected to one end of both support plates respectively, and the tops of both rectangular frames are fixedly connected to one adjacent end of both sliding plates respectively. Sliders are arranged below both support rods, and the tops of both sliders are rotatably connected to one end of both support rods respectively. Pressing rods are fixedly connected to the bottoms of both sliders, and sponge sleeves are fixedly sleeved on the outer side walls of both pressing rods. Moving plates are arranged below both support rods, and two slide rails are fixedly connected between the tops of both moving plates. Both sliders are slidably connected between both slide rails. The connecting plate is sleeved on the outer side wall of the movable end of the first electric push rod. When the first electric push rod is started to move its movable end, the connecting plate and the connecting block can be synchronously driven to move. The connecting plate can only rotate on the first electric push rod and cannot slide. The outer side walls of both sponge sleeves are used to adhere the grinding plates, and both pressing rods are located inside the inner ring of the bearing to be ground, so that the grinding plates on both sponge sleeves can grind the inner side wall of the inner ring of the bearing, thus facilitating assembly.

[0009] Furthermore, a first annular guide rail and a second annular guide rail are arranged between the two arms of the U-shaped frame, and the first annular guide rail is located inside the second annular guide rail. Support plates are fixedly connected to the top ends of one side of both frames, and clamping plates are fixedly connected to the top ends of one side of both moving plates. Both clamping plates are slidably connected inside the first annular guide rail, and both support plates are slidably connected inside the second annular guide rail. The first annular guide rail and the second annular guide rail can be used to limit the two moving plates and the two frames to always move in the same plane through the clamping plates and the support plates.

[0010] Furthermore, two screwing rods are rotatably connected to the tops of the first annular guide rail and the second annular guide rail respectively. Four screwing holes are formed in the inner top surface of the U-shaped frame, and the four screwing rods are respectively screwed into the four screwing holes. By rotating the four screwing rods, the heights of the first annular guide rail and the second annular guide rail are adjusted, so as to limit the heights of the first annular guide rail and the second annular guide rail, so that the first annular guide rail and the second annular guide rail define the heights of the two moving plates and the two frames through the clamping plates and the supporting plates. When the user places the inner ring of the bearing, the heights of the two frames and the two moving plates can be controlled by rotating the screwing rods, so as to drive the two sliders and the two sliding plates to move vertically upward or downward. When the two sliders and the two sliding plates move vertically, the adjacent support rods or support plates are driven to rotate, so that the two sliders and the two sliding plates move towards or away from each other. When the first electric push rod is not started, the inner ring of the bearing is placed on the moving mechanism, and then the height of the first annular guide rail is adjusted, so that the two sliders drive the two resisting rods to support the inner side wall of the inner ring of the bearing, so that the inner ring of the bearing is automatically positioned, and the two sponge sleeves are in contact with the inner side wall of the inner ring of the bearing and slightly contract. Then, the height of the second annular guide rail, the positions of the two rollers and the thicknesses of the two grinding belts are adjusted, and the positions of the two rollers are fixed by the screw rods and the thicknesses of the two grinding belts are fixed, so that the two sliding plates drive the two rectangular frames to clamp the outer ring of the bearing, and the two grinding belts are stuck on the raceways of the inner ring of the bearing. Then, the user uses the moving mechanism and the adjusting mechanism to cooperate with the two sponge sleeves and the grinding plates adhered by the two sponge stickers to polish the inner ring of the bearing. During use, the first electric push rod is started, so that the first electric push rod drives the connecting plate and the connecting block to descend synchronously. The connecting plate drives the two sliding plates to move away from each other through the two support plates, so that the two rectangular frames move away from each other, and the sponge stickers on the two rectangular frames are slightly reset so that the adhered grinding plates are attached to the outer side wall of the inner ring of the bearing. At the same time, the connecting block moves downward to drive the two sliders to move away from each other through the two support rods, so that the sponge sleeves on the two resisting rods tightly contact the inner side wall of the inner ring of the bearing, so as to fix the inner ring of the bearing by the two resisting rods. After the first electric push rod is reset and moves upward for a part, the connecting plate will drive the two sliding plates to move towards each other through the two support plates, so that the sponge stickers on the two rectangular frames are compressed, so that the two rectangular frames clamp and fix the inner ring of the bearing, and the connecting block moves upward to drive the two sliders to move towards each other through the two support rods, so that the two resisting rods move towards each other for a part, so that the two sponge sleeves can recover due to their own characteristics, and the grinding plates on the two sponge sleeves are attached to the inner side wall of the inner ring of the bearing.

[0011] Furthermore, the moving mechanism includes a circular plate which is located inside the top opening of the barrel. A groove is formed on the outer side wall of the circular plate, and a rotating ring is rotatably sleeved on the outer side wall of the circular plate. A convex ring is fixedly connected to the inner side wall of the rotating ring, and the convex ring is rotatably clamped inside the groove. The rotating ring is slidably inserted into the top opening of the barrel. A circular block is fixedly connected to the bottom surface of the circular plate, and the center of the bottom surface of the circular block is rotatably connected to a water storage box. The center of the inner bottom surface of the barrel is fixedly connected to a cylinder, and the movable end of the cylinder is fixedly connected to the center of the bottom surface of the water storage box. Two fixing rods are fixedly connected to the top surface of the circular plate. Circular through holes are formed at the tops of the two moving plates, and the two fixing rods are respectively slidably sleeved inside the two circular through holes. Card slots are formed on the opposite sides of the two frames, and connecting rods are slidably clamped inside the four card slots. The bottoms of the four connecting rods are fixedly connected to the top surface of the rotating ring. By starting the cylinder, the circular plate can be driven to move up and down, and the rotating ring can be synchronously moved up and down through the groove and the convex ring. When in use, the inner ring of the bearing is placed on the circular plate, and then starting the cylinder to drive the circular plate to move up can make the inner ring of the bearing enter between the two rectangular frames and the two abutting rods. And through the two fixing rods, when the circular plate rotates, the two moving plates can be driven to control the two abutting rods to rotate synchronously with the circular plate by relying on the two slide rails. Through the four connecting rods, when the rotating ring rotates, the two frames can be driven to drive the two rectangular frames to rotate synchronously with the rotating ring.

[0012] Furthermore, a water storage groove is formed on the top surface of the circular plate, and a drain hole is formed on the bottom surface of the water storage groove. The inside of the drain hole is communicated with the inside of the water storage box. A connecting pipe orifice with a catheter connected to the inner side wall is formed on the outer side wall of the water storage box, and one end of the catheter penetrates through the inner side wall of the barrel. By continuously injecting water into the water storage groove, then during the polishing process, debris and other items will fall into the water storage groove. The water flow will carry the debris through the drain hole to the inside of the water storage box, and the debris will be discharged from the catheter, so as to facilitate the cleaning of the debris worn by the polishing plate and the debris polished off during the polishing process.

[0013] Furthermore, the adjusting mechanism includes a guide plate, one end of which is fixedly connected to the inner side wall of the barrel. The top surface of the guide plate is slidably connected with a mounting plate, and the top surface of the mounting plate is fixedly connected with a driving motor. The motor shaft of the driving motor is fixedly connected with a rotating rod, and the top end of the rotating rod is fixedly connected with a gear. The bottom surface of the rotating ring is fixedly connected with a fixed ring plate, and a plurality of tooth blocks are fixedly connected to the inner side wall of the fixed ring plate and the outer side wall of the round block. The gear is located between the fixed ring plate and the round block and meshes with the adjacent tooth blocks. The inner side wall of the barrel is fixedly connected with a second electric push rod. One side of the mounting plate is fixedly connected with a push plate, and the movable end of the second electric push rod is fixedly connected with one side of the push plate. By starting the second electric push rod, the driving motor can drive the gear to move synchronously with the movable end of the second electric push rod through the rotating rod, so that the second electric push rod can control the gear to mesh with the tooth blocks on the round block or the tooth blocks on the fixed ring plate. Then, by starting the driving motor, the rotating rod can drive the gear to rotate, and the gear can drive the meshed round block or fixed ring plate to rotate. The fixed ring plate or the round block can drive the two rectangular frames to rotate synchronously with the fixed ring plate through the connecting rod or the fixed rod, or drive the two abutting rods to rotate synchronously with the round block to polish the inner and outer side walls of the bearing inner ring.

[0014] Furthermore, the cross section of the fixed ring plate is an L-shaped structure. A second annular groove is formed in the bottom surface of the fixed ring plate, and a first annular groove is formed in the bottom surface of the round block. The outer side wall of the rotating rod is rotatably sleeved with a plug rod, and a sliding hole is formed in the outer side wall of the barrel. One end of the plug rod is slidably inserted into the sliding hole. The top surface of the plug rod is fixedly connected with two abutting plates, and the two abutting plates are respectively located inside the first annular groove and the second annular groove. When the second electric push rod drives the driving motor to move, the driving motor can pull the plug rod to move synchronously through the rotating rod. When one abutting plate on the plug rod abuts against the side wall of the first annular groove and makes it difficult for the round block to rotate, the other abutting plate does not contact any side wall of the second annular groove, and the gear meshes with the tooth blocks on the fixed ring plate. When one abutting plate does not abut against any side wall of the first annular groove, the other abutting plate abuts against the side wall of the second annular groove and makes it difficult for the fixed ring plate to rotate, and the gear meshes with the tooth blocks on the round block. When the round block drives the round plate to rotate, the fixed ring plate and the rotating ring do not move. When the fixed ring plate and the rotating ring rotate, the round block and the round plate do not move. When the two abutting rods abut against the fixed bearing inner ring, the rotating ring drives the two rectangular frames to rotate to polish the outer side wall of the bearing inner ring. When the two rectangular frames clamp and fix the bearing inner ring, the round plate drives the two abutting rods to rotate to polish the inner side wall of the bearing inner ring.

[0015] Furthermore, both opposite sides of the abutting plate are arc-shaped surfaces, so that the contact surface between the abutting plate and the adjacent side wall of the first annular groove or the second annular groove is larger.

[0016] Furthermore, one side of the U-shaped frame is fixedly connected with a connecting ring, and a water outlet pipe is fixedly sleeved inside the connecting ring. A spray head is installed at one end of the water outlet pipe. By inserting the water outlet pipe into the connecting ring and then injecting water into the water outlet pipe through a water pump, the water flows out from the spray head to spray the inner ring of the bearing being polished below, preventing the sundries generated during the polishing process from flying.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. Place the inner ring of the bearing on the moving mechanism, then start the moving mechanism to move the inner ring of the bearing between the two grinding mechanisms and inside the changing mechanism. Then start the changing mechanism to press against the inner side wall of the inner ring of the bearing for fixation. Next, start the adjusting mechanism to drive the moving mechanism to start, so that the moving mechanism drives the two grinding mechanisms to grind the outer side wall of the inner ring of the bearing. Then start the changing mechanism to drive the two grinding mechanisms to clamp the inner ring of the bearing. Then start the adjusting mechanism to drive the changing mechanism to rotate through the moving mechanism, so that the changing mechanism grinds the inner side wall of the inner ring of the bearing, thereby automatically grinding the inner and outer side walls of the inner ring of the bearing.

[0019] 2. Place the inner ring of the bearing on the circular plate, then start the cylinder to lift the circular plate, so that the inner ring of the bearing moves inside the changing mechanism and between the two grinding mechanisms. Then, after the changing mechanism and the two grinding mechanisms alternately clamp and fix the inner ring of the bearing, start the cylinder to lower, so that the circular plate returns to its original position. During grinding, insert the water outlet pipe equipped with a spray head into the connecting ring and inject water into the water outlet pipe through a water pump, so that the water mist carries the sundries generated during grinding and falls into the water storage tank, and flows through the drain hole into the water storage box and is discharged to the outside through the conduit connected to the connecting pipe, facilitating the cleaning of the sundries generated during the grinding process and reducing the flying of sundries.

[0020] 3. By rotating two rollers, adjust the thickness of the abrasive belts on the two rollers so that they are in contact with the raceways on the inner ring of the bearing. Then place the inner ring of the bearing on the circular plate and use the air cylinder to lift it to between the two abutting rods and the two rectangular frames. Then rotate the four screwing rods to adjust the heights and the distance between the two rectangular frames and the two abutting rods so that the two abutting rods and the two rectangular frames are in contact with the inner and outer side walls of the inner ring of the bearing. Then adjust the positions of the two U-shaped frames so that the two abrasive belts are stuck at the raceways. Then rotate the two screw rods to make the two triangular plates abut against the abrasive belts to fix the abrasive belts and the adjacent U-shaped frames. Then lower the circular plate, and then start the first electric push rod to make its movable end move, driving the connecting plate and the connecting block to move synchronously, so that the sponge sleeves and the adhered grinding plates on the two abutting rods are compressed, tightly fixing the inner ring of the bearing, and making the two rectangular frames slightly separated from the inner ring of the bearing, so that the grinding plates on the two sponges are in contact with the inner ring of the bearing, and making the abrasive belts in contact with the raceways. Then use the adjusting mechanism to drive the rotating ring to rotate while the circular plate remains stationary to grind the outer side wall of the inner ring of the bearing. Then reverse-start the first electric push rod to make the grinding plates adhered to the two abutting rods contact the inner side wall of the inner ring of the bearing, and make the sponges on the two rectangular frames be squeezed, so that the two rectangular frames clamp the inner ring of the bearing. Then start the adjusting mechanism to drive the circular plate to rotate while the rotating ring remains stationary, thereby grinding the inner side wall of the inner ring of the bearing;

[0021] 4. By starting the second electric push rod to drive the driving motor to move, the driving motor can pull the insertion rod to move synchronously through the rotating rod. When one abutting plate on the insertion rod abuts against the side wall of the first annular groove making it difficult for the circular block to rotate, the other abutting plate does not contact any side wall of the second annular groove, and the gear meshes with the tooth block on the fixed ring plate. Start the driving motor to make the gear drive the circular block and the circular plate to rotate through the tooth block. When one abutting plate does not abut against any side wall of the first annular groove, the other abutting plate abuts against the side wall of the second annular groove making it difficult for the fixed ring plate to rotate, and the gear meshes with the tooth block on the circular block. Then start the driving motor to make the gear drive the fixed ring plate and the rotating ring to rotate synchronously through the adjacent tooth blocks. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0034] Please refer to Figures 1-9As shown in the figure, a processing device for the inner ring of a sealed bearing includes a barrel body 100. Above the barrel body 100, there is a U-shaped frame 200, and one end of each of the two arms of the U-shaped frame 200 is fixedly connected to the outer side wall of the barrel body 100. A variable mechanism 300 is arranged between the two arms of the U-shaped frame 200, and two grinding mechanisms 600 are arranged on the variable mechanism 300. An adjusting mechanism 500 is arranged inside the barrel body 100, and a moving mechanism 400 is arranged above the adjusting mechanism 500;

[0035] The grinding mechanism 600 includes a rectangular frame 610. Sliding grooves 611 are formed on the opposite inner side walls of the rectangular frame 610. A U-shaped frame 630 is slidably connected between the two sliding grooves 611. A roller 640 is rotatably connected between the two arms of the U-shaped frame 630. A grinding belt 641 is fixedly wound around the outer side wall of the roller 640. A triangular plate 650 is arranged between the two arms of the U-shaped frame 630. One edge of the triangular plate 650 abuts against the grinding belt 641. A threaded hole 631 is formed on one side of the U-shaped frame 630, and a screw 651 is screwed into the threaded hole 631. One end of the screw 651 is rotatably connected to one side of the triangular plate 650. Sponge stickers 620 are fixedly connected to both sides of one side of the rectangular frame 610. Rectangular blocks are arranged on the opposite sides of the two U-shaped frames 630. The U-shaped frame 630 slides inside the adjacent sliding grooves 611 through the rectangular blocks and cannot rotate. By rotating the rollers 640 on the two grinding mechanisms 600, the thickness of the grinding belt 641 can be adjusted. Then, rotate the screw 651 to press the triangular plate 650 against the grinding belt 641 to make it stop rotating to fix the thickness of the grinding belt 641 on the roller 640. And by rotating the screw 651, the rectangular blocks on the U-shaped frame 630 are made to abut against the side walls of the sliding grooves 611, making it difficult for the U-shaped frame 630 to slide. By adhering items such as grinding plates on the sponge stickers 620 to grind the outer side wall of the inner ring of the bearing. Then, clamp the inner ring of the bearing with the two rectangular frames 610. Then, slide the two U-shaped frames 630 so that the grinding belts 641 on the two rollers 640 are stuck on the raceways on the outer side wall of the inner ring of the bearing. One side of the two U-shaped frames 630 is an arc surface, so that the grinding plates on the two sponge stickers 620 can contact the outer side wall of the inner ring of the bearing and perform grinding, enabling the user to adjust according to inner rings of different specifications, so that the outer side wall and the raceway of the inner ring of the bearing are fully ground. And through the cooperation of the moving mechanism 400, the adjusting mechanism 500 and the variable mechanism 300, the user does not need to manually grind the inner ring of the bearing. Since the grinding belt 641 is formed by winding, when being squeezed, the gaps between the windings will be compressed, and when not being compressed, the grinding belt 641 will naturally spread out, increasing the diameter of the roller formed by its winding.

[0036] The moving mechanism 300 includes a first electric push rod 310, and one end of the first electric push rod 310 is fixedly connected to the center of the inner top surface of the U-shaped frame 200. A connecting plate 320 and a connecting block 330 are arranged below the first electric push rod 310. The movable end of the first electric push rod 310 penetrates through the center of the top surface of the connecting plate 320 and is fixedly connected to the center of the top surface of the connecting block 330. The center of the top surface of the connecting plate 320 is rotatably connected to the outer side wall of the movable end of the first electric push rod 310. Support plates 321 are rotatably connected to both opposite sides of the connecting plate 320. Support rods 331 are rotatably connected to both ends of the connecting block 330. Frame bodies 340 are arranged below both support plates 321. Sliding plates 341 are slidably connected to the interiors of both frame bodies 340. One adjacent end of both sliding plates 341 is rotatably connected to one end of both support plates 321 respectively. The tops of both rectangular frames 610 are fixedly connected to one adjacent end of both sliding plates 341 respectively. Sliders 360 are arranged below both support rods 331. The tops of both sliders 360 are rotatably connected to one end of both support rods 331 respectively. Bracing rods 361 are fixedly connected to the lower sides of both sliders 360. Sponge sleeves 362 are fixedly sleeved on the outer side walls of both bracing rods 361. Moving plates 350 are arranged below both support rods 331. Two slide rails 352 are fixedly connected between the tops of both moving plates 350. Both sliders 360 are slidably connected between both slide rails 352. The connecting plate 320 is sleeved on the outer side wall of the movable end of the first electric push rod 310. When the first electric push rod 310 is started to move its movable end, it can drive the connecting plate 320 and the connecting block 330 to move synchronously. The connecting plate 320 can only rotate on the first electric push rod 310 and cannot slide. The outer side walls of both sponge sleeves 362 are used for adhering abrasive plates. Both bracing rods 361 are located inside the inner ring of the bearing to be polished, so that the abrasive plates on both sponge sleeves 362 can polish the inner side wall of the inner ring of the bearing, thus facilitating assembly.

[0037] A first annular guide rail 370 and a second annular guide rail 380 are arranged between the two arms of the U-shaped frame 200. The first annular guide rail 370 is located inside the second annular guide rail 380. Support plates 343 are fixedly connected to the top ends of one side of both frame bodies 340. Clamping plates 353 are fixedly connected to the top ends of one side of both moving plates 350. Both clamping plates 353 are slidably connected inside the first annular guide rail 370. Both support plates 343 are slidably connected inside the second annular guide rail 380. By using the first annular guide rail 370 and the second annular guide rail 380, the two moving plates 350 and the two frame bodies 340 can be limited to always move in the same plane through the clamping plates 353 and the support plates 343.

[0038] Two screwing rods 390 are rotatably connected to the tops of the first annular guide rail 370 and the second annular guide rail 380 respectively. Four screwing holes 201 are formed in the inner top surface of the U-shaped frame 200, and the four screwing rods 390 are respectively screwed into the four screwing holes 201. By rotating the four screwing rods 390, the heights of the first annular guide rail 370 and the second annular guide rail 380 are adjusted, so as to limit the heights of the first annular guide rail 370 and the second annular guide rail 380, so that the first annular guide rail 370 and the second annular guide rail 380 limit the heights of the two moving plates 350 and the two frames 340 through the clamping plates 353 and the supporting plates 343. Thus, when the user places the inner ring of the bearing, the heights of the two frames 340 and the two moving plates 350 can be controlled by rotating the screwing rods 390, so as to drive the two sliders 360 and the two sliding plates 341 to move vertically upward or downward. When the two sliders 360 and the two sliding plates 341 move vertically, the adjacent support rods 331 or support plates 321 are driven to rotate, so that the two sliders 360 and the two sliding plates 341 move toward or away from each other. When the first electric push rod 310 is not started, the inner ring of the bearing is placed on the moving mechanism 400, and then the height of the first annular guide rail 370 is adjusted, so that the two sliders 360 drive the two abutting rods 361 to support the inner side wall of the inner ring of the bearing, so that the inner ring of the bearing is automatically positioned, and the two sponge sleeves 362 are in contact with the inner side wall of the inner ring of the bearing and slightly contract. Then, the height of the second annular guide rail 380, the positions of the two rollers 640 and the thicknesses of the two abrasive belts 641 are adjusted, and the positions of the two rollers 640 are fixed and the thicknesses of the two abrasive belts 641 are fixed by using the screw rod 651, so that the two sliding plates 341 drive the two rectangular frames 610 to clamp the outer ring of the bearing, and the two abrasive belts 641 are stuck on the raceways of the inner ring of the bearing. Then, the user uses the moving mechanism 400 and the adjusting mechanism 500 to cooperate with the abrasive plates adhered by the two sponge sleeves 362 and the two sponge stickers 620 to polish the inner ring of the bearing. During use, the first electric push rod 310 is started, so that the first electric push rod 310 drives the connecting plate 320 and the connecting block 330 to descend synchronously, so that the connecting plate 320 drives the two sliding plates 341 to move away from each other through the two support plates 321, so that the two rectangular frames 610 move away from each other, and the sponge stickers 620 on the two rectangular frames 610 are slightly reset so that the abrasive plates adhered thereto are abutted against the outer side wall of the inner ring of the bearing. At the same time, the connecting block 330 moves downward and drives the two sliders 360 to move away from each other through the two support rods 331, so that the sponge sleeves 362 on the two abutting rods 361 tightly abut against the inner side wall of the inner ring of the bearing, so that the two abutting rods 361 fix the inner ring of the bearing;After the first electric push rod 310 resets and moves upward, the connecting plate 320 will drive the two sliding plates 341 to move towards each other through the two support plates 321, compressing the sponge stickers 620 on the two rectangular frames 610, so as to clamp and fix the inner ring of the bearing by the two rectangular frames 610. The connecting block 330 moves upward and drives the two sliders 360 to move towards each other through the two support rods 331, causing the two abutting rods 361 to move towards each other partially, enabling the two sponge sleeves 362 to restore themselves due to their own characteristics, and making the polishing plates on the two sponge sleeves 362 abut against the inner side wall of the inner ring of the bearing.

[0039] The moving mechanism 400 includes a circular plate 410, and the circular plate 410 is located inside the top opening of the barrel 100. A groove 412 is formed on the outer side wall of the circular plate 410, and a rotating ring 420 is rotatably sleeved on the outer side wall of the circular plate 410. A convex ring 421 is fixedly connected to the inner side wall of the rotating ring 420, and the convex ring 421 is rotatably clamped inside the groove 412. The rotating ring 420 is slidably embedded in the top opening of the barrel 100. A circular block 430 is fixedly connected to the bottom surface of the circular plate 410, and the center of the bottom surface of the circular block 430 is rotatably connected to a water storage box 450. A cylinder 460 is fixedly connected to the center of the inner bottom surface of the barrel 100, and the movable end of the cylinder 460 is fixedly connected to the center of the bottom surface of the water storage box 450. Two fixing rods 413 are fixedly connected to the top surface of the circular plate 410. Circular through holes 351 are formed at the tops of the two moving plates 350, and the two fixing rods 413 are respectively slidably sleeved inside the two circular through holes 351. Card slots 342 are formed on the opposite sides of the two frames 340, and connecting rods 422 are slidably clamped inside the four card slots 342. The bottoms of the four connecting rods 422 are fixedly connected to the top surface of the rotating ring 420. By starting the cylinder 460, the circular plate 410 can be driven to move up and down, and the rotating ring 420 can be synchronously moved up and down through the groove 412 and the convex ring 421. During use, place the inner ring of the bearing on the circular plate 410, and then start the cylinder 460 to drive the circular plate 410 to move upward, so that the inner ring of the bearing can enter between the two rectangular frames 610 and the two abutting rods 361. And through the two fixing rods 413, the two moving plates 350 can be driven to control the two abutting rods 361 to rotate synchronously with the circular plate 410 when the circular plate 410 rotates by relying on the two slide rails 352. Through the four connecting rods 422, the two frames 340 can be driven when the rotating ring 420 rotates, thereby driving the two rectangular frames 610 to rotate synchronously with the rotating ring 420.

[0040] The top surface of the circular plate 410 is provided with a water storage tank 411, and a drain hole 401 is provided on the bottom surface of the water storage tank 411. The inside of the drain hole 401 is communicated with the inside of the water storage box 450. A connecting pipe opening 451 with a conduit connected to the inner side wall is provided on the outer side wall of the water storage box 450. One end of the conduit penetrates the inner side wall of the barrel 100. By continuously injecting water into the water storage tank 411, then during the polishing process, debris and other items will fall into the water storage tank 411. The water flow will carry the sundries through the drain hole 401 and fall into the water storage box 450, and the sundries will be discharged from the conduit, so as to facilitate the cleaning of the debris worn by the polishing plate and the debris polished off during the polishing process.

[0041] The adjusting mechanism 500 includes a guide plate 510, and one end of the guide plate 510 is fixedly connected to the inner side wall of the barrel 100. The top surface of the guide plate 510 is slidably connected with a mounting plate 520, and a driving motor 530 is fixedly connected to the top surface of the mounting plate 520. The motor shaft of the driving motor 530 is fixedly connected with a rotating rod 540, and a gear 541 is fixedly connected to the top end of the rotating rod 540. A fixed ring plate 440 is fixedly connected to the bottom surface of the rotating ring 420, and a plurality of tooth blocks 470 are fixedly connected to the inner side wall of the fixed ring plate 440 and the outer side wall of the round block 430. The gear 541 is located between the fixed ring plate 440 and the round block 430, and the gear 541 meshes with the adjacent tooth blocks 470. A second electric push rod 560 is fixedly connected to the inner side wall of the barrel 100. A push plate 521 is fixedly connected to one side of the mounting plate 520, and the movable end of the second electric push rod 560 is fixedly connected to one side of the push plate 521. By starting the second electric push rod 560, the driving motor 530 drives the gear 541 to move synchronously with the movable end of the second electric push rod 560 through the rotating rod 540, so that the second electric push rod 560 can control the gear 541 to mesh with the tooth blocks 470 on the round block 430 or the tooth blocks 470 on the fixed ring plate 440. Then start the driving motor 530, and the rotating rod 540 can drive the gear 541 to rotate, and the gear 541 drives the engaged round block 430 or fixed ring plate 440 to rotate. The fixed ring plate 440 or the round block 430 can drive the two rectangular frames 610 to rotate synchronously with the fixed ring plate 440 or the two abutting rods 361 to rotate synchronously with the round block 430 to polish the inner and outer side walls of the inner ring of the bearing.

[0042] The cross-section of the fixed ring plate 440 is an L-shaped structure. A second annular groove 441 is formed on the bottom surface of the fixed ring plate 440, and a first annular groove 431 is formed on the bottom surface of the round block 430. A plug rod 550 is rotatably sleeved on the outer side wall of the rotating rod 540, and a sliding hole 101 is formed on the outer side wall of the barrel 100. One end of the plug rod 550 is slidably inserted into the sliding hole 101. Two abutting plates 551 are fixedly connected to the top surface of the plug rod 550, and the two abutting plates 551 are respectively located inside the first annular groove 431 and the second annular groove 441. When the second electric push rod 560 drives the driving motor 530 to move, the driving motor 530 can pull the plug rod 550 to move synchronously through the rotating rod 540. When one abutting plate 551 on the plug rod 550 abuts against the side wall of the first annular groove 431 and makes it difficult for the round block 430 to rotate, the other abutting plate 551 does not contact any side wall of the second annular groove 441. And the gear 541 meshes with the tooth block 470 on the fixed ring plate 440. When one abutting plate 551 does not abut against any side wall of the first annular groove 431, the other abutting plate 551 abuts against the side wall of the second annular groove 441 and makes it difficult for the fixed ring plate 440 to rotate. And the gear 541 meshes with the tooth block 470 on the round block 430. When the round block 430 drives the round plate 410 to rotate, the fixed ring plate 440 and the rotating ring 420 do not move. When the fixed ring plate 440 and the rotating ring 420 rotate, the round block 430 and the round plate 410 do not move. When the two abutting rods 361 abut against the inner ring of the fixed bearing, the rotating ring 420 drives the two rectangular frames 610 to rotate to polish the outer side wall of the inner ring of the bearing. When the two rectangular frames 610 clamp the inner ring of the bearing and fix it, the round plate 410 drives the two abutting rods 361 to rotate to polish the inner side wall of the inner ring of the bearing.

[0043] Both opposite sides of the abutting plate 551 are arc-shaped surfaces, so that the contact surface between the abutting plate 551 and the adjacent side wall of the first annular groove 431 or the second annular groove 441 is larger.

[0044] One side of the U-shaped frame 200 is fixedly connected with a connecting ring 480, and a water outlet pipe 481 is fixedly sleeved inside the connecting ring 480. A spray head is installed at one end of the water outlet pipe 481. By inserting the water outlet pipe 481 into the connecting ring 480 and then injecting water into the water outlet pipe 481 through a water pump, the water flow is sprayed out from the spray head to spray the inner ring of the bearing being polished below, so as to prevent the sundries generated during the polishing process from flying.

[0045] Working principle: When in use, attach two arc-shaped grinding plates to the outer side walls of two sponge sleeves 362, and the two arc-shaped grinding plates are located on the side of the two sponge sleeves 362 facing away from each other. Then attach four sponge stickers 620 to the grinding plates. Next, connect the water outlet end of the water outlet pipe 481 to the spray head, and clamp the water outlet pipe 481 inside the connecting ring 480. Then, set controllers on the U-shaped frame 200, the inner bottom surface of the barrel 100, the inner side wall of the barrel 100, and the mounting plate 520 to control the opening and closing of the first electric push rod 310, the cylinder 460, the second electric push rod 560, and the drive motor 530 respectively. Connect the water inlet end of the water outlet pipe 481 to an external water pump, so that water flows through the spray head at the water outlet end of the water outlet pipe 481 and sprays downward from the U-shaped frame 200. Connect a conduit at the connecting pipe orifice 451, and pass the conduit through the side wall of the barrel 100, so that water flows through the water storage tank 411 and then flows into the water storage box 450 through the drain hole 401. Then the water flows out of the barrel 100 through the conduit and is discharged to the outside;

[0046] Place the inner ring of the bearing on the circular plate 410, and then start the cylinder 460 to drive the circular plate 410 to move upward, so that the inner ring of the bearing moves between the two rectangular frames 610, and the two abutting rods 361 are located inside the inner ring of the bearing. Then the user rotates the four screwing rods 390 to adjust the heights of the first annular guide rail 370 and the second annular guide rail 380, so that the first annular guide rail 370 and the second annular guide rail 380 drive the adjacent moving plates 350 and the adjacent frames 340 to move synchronously through the clamping plates 353 and the supporting plates 343. When the two frames 340 move upward, the two frames 340 drive the adjacent support plates 321 to rotate, so that the two frames 340 move away from each other. When the two frames 340 move downward, the two frames 340 move toward each other. When the two moving plates 350 move upward, they drive the adjacent support rods 331 to rotate, so that the two sliders 360 move away from each other. Then when the two sliders 360 move downward, the two sliders 360 move toward each other;

[0047] Then adjust the four screwing rods 390 so that the grinding plates attached to the sponge sleeves 362 on the two sliders 360 are close to the inner side wall of the inner ring of the bearing, and the grinding plates adhered to the sponge stickers 620 on the rectangular frames 610 connected to the two frames 340 are close to the outer side wall of the inner ring of the bearing. Slide and adjust the two U-shaped frames 630 so that the abrasive belts 641 on the two rollers 640 are attached to the raceway on the inner ring of the bearing. Then rotate the two screw rods 651 so that the two triangular plates 650 abut and fix the adjacent abrasive belts 641, and the rectangular blocks on the adjacent U-shaped frames 630 abut the adjacent sliding grooves 611 for fixation. Then start the cylinder 460 to reset the circular plate 410;

[0048] Start the first electric push rod 310, so that the first electric push rod 310 drives the connecting plate 320 and the connecting block 330 to descend synchronously, so that the connecting plate 320 drives the two sliding plates 341 to move away from each other through the two support plates 321, so that the two rectangular frames 610 move away from each other, so that the sponge stickers 620 on the two rectangular frames 610 are slightly reset to make the polishing plates adhered thereto abut against the outer side wall of the inner ring of the bearing, and the two abrasive belts 641 are not greatly squeezed. Due to the gap between the two abrasive belts 641, the two abrasive belts 641 abut against the raceway. At the same time, the connecting block 330 moves downward and drives the two sliders 360 to move away from each other through the two support rods 331, so that the sponge sleeves 362 on the two abutting rods 361 tightly abut against the inner side wall of the inner ring of the bearing, so as to fix the inner ring of the bearing by the two abutting rods 361; When the first electric push rod 310 is reset and moves upward by a part, the connecting plate 320 will drive the two sliding plates 341 to move towards each other through the two support plates 321, so that the sponge stickers 620 on the two rectangular frames 610 are compressed, so as to clamp and fix the inner ring of the bearing by the two rectangular frames 610, and the two abrasive belts 641 are compressed and become dense and adhere to the raceway. The connecting block 330 moves upward and drives the two sliders 360 to move towards each other through the two support rods 331, so that the two abutting rods 361 move towards each other by a part, so that the two sponge sleeves 362 can be restored due to their own characteristics, so that the polishing plates on the two sponge sleeves 362 abut against the inner side wall of the inner ring of the bearing;

[0049] When the two abutting rods 361 abut against and fix the inner ring of the bearing, the second electric push rod 560 drives the driving motor 530 to move, so that the driving motor 530 drives the insertion rod 550 to move synchronously through the rotating rod 540, so that a abutting plate 551 on the insertion rod 550 abuts against the side wall of the first annular groove 431, making it difficult for the round block 430 to rotate, and the other abutting plate 551 does not contact any side wall of the second annular groove 441, and the gear 541 meshes with the tooth block 470 on the fixed ring plate 440. Then start the driving motor 530, so that the driving motor 530 drives the gear 541 to rotate through the rotating rod 540, so that the gear 541 drives the adjacent fixed ring plate 440 and the rotating ring 420 to rotate synchronously through the tooth block 470, so that the rotating ring 420 drives the two rectangular frames 610 to rotate synchronously through the four connecting rods 422 and the two frames 340, and polish the outer side wall of the inner ring of the bearing;

[0050] Then, when the two rectangular frames 610 clamp the inner ring of the bearing, start the second electric push rod 560 to drive the driving motor 530 to pull the inserting rod 550 to move, so that one abutting plate 551 does not contact any side wall of the first annular groove 431, and the other abutting plate 551 contacts the side wall of the second annular groove 441 to make it difficult for the fixed ring plate 440 to rotate. Moreover, the gear 541 meshes with the tooth block 470 on the round block 430. Then start the driving motor 530 to make the gear 541 drive the round block 430 and the round plate 410 to rotate through the adjacent tooth blocks 470, so that the round plate 410 drives the two abutting rods 361 to rotate synchronously through the two fixing rods 413 and the two moving plates 350, and the grinding plates on the sponge sleeves 362 connected by the two abutting rods 361 grind the inner side wall of the bearing;

[0051] After use, the user manually rotates and combines the two screwing rods 390 to adjust the height of the second annular guide rail 380, so that the abrasive belts 641 on the two rectangular frames 610 are separated from the raceway. Then, remove the inner ring of the bearing, and then put the inner ring of a new bearing of the same model on the two abutting rods 361, and then rotate and combine the two screwing rods 390 to reset the two rectangular frames 610 and perform grinding again.
