Technical Field
[0001] This utility model belongs to the technical field of bearing ring processing equipment, specifically a bearing ring grinding device. Background Technology
[0002] During the manufacturing process, bearing rings will have machining marks such as turning and milling left on their surface, resulting in a rough surface. Grinding can effectively reduce the surface roughness, thereby reducing friction. Grinding is performed using a grinding device.
[0003] When using existing grinding equipment to grind bearing rings, it can usually only target the inner ring or the outer ring, and cannot be adapted to both the inner and outer rings at the same time. If the inner ring or the outer ring needs to be ground separately, the grinding equipment needs to be replaced, which increases the cost. Summary of the Invention
[0004] The purpose of this invention is to provide a bearing ring grinding device that can grind the inner or outer ring of the bearing ring separately, thus having a wider range of applications and reducing costs.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a bearing ring grinding device is provided, including a worktable, a fixing block is fixedly connected to the upper surface of the worktable, a rotating groove is formed inside the fixing block, a first turntable is movably mounted on the surface of the rotating groove, four inclined grooves are formed on the side wall of the first turntable, four straight grooves are formed on the side wall of the fixing block, a locking pin is provided inside the inclined groove, the locking pin is located inside the straight groove, a clamping member is fixedly connected to the side wall of the locking pin, a second rotating shaft is fixedly connected to the side wall of the first turntable, a first rotating block is fixedly connected to the end of the second rotating shaft away from the first turntable, and a first roller is fixedly connected to the side wall of the first rotating block.
[0006] Optionally, the side wall of the fixing block is provided with a limiting groove, and there are multiple limiting grooves. The side wall of the clamping member is fixedly connected to the limiting block, and the limiting block is located inside the limiting groove.
[0007] Optionally, the upper surface of the workbench is provided with a first movable groove, the inner wall of the first movable groove is movably mounted with a first threaded rod, and the outer surface of the first threaded rod is threadedly connected with a movable block.
[0008] Optionally, a second rotating block is fixedly connected to one end of the first threaded rod, and a second roller is fixedly connected to the side of the second rotating block away from the first threaded rod.
[0009] Optionally, a first motor is fixedly connected to the side wall of the movable block, a first rotating shaft is fixedly connected to the output end of the first motor, and a second turntable is fixedly connected to the end of the first rotating shaft away from the first motor.
[0010] Optionally, the second turntable has an internal mounting groove, a second motor is fixedly connected to the inner wall of the mounting groove, a second threaded rod is fixedly connected to the output end of the second motor, a movable part is threadedly connected to the outer surface of the second threaded rod, a third motor is fixedly connected to the side wall of the movable part, and a grinding rod is fixedly connected to the output end of the third motor.
[0011] Optionally, the side wall of the second turntable is provided with a second moving groove, and the moving part is located inside the second moving groove.
[0012] Optionally, the lower surface of the first rotating block is fixedly connected with four legs, the upper surface of the workbench is provided with a third moving groove, the inner wall of the third moving groove is fixedly connected with a slide rod, and the outer surface of the slide rod is fitted with a moving block.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention comprises a clamping component, a first roller, a first rotating block, a second rotating shaft, a first turntable, an inclined groove, a straight groove, and a locking pin. The clamping component can grind the inner surface of the inner ring or the outer surface of the outer ring of the bearing race. Rotating the first roller causes the first rotating block, the second rotating shaft, and the first turntable to rotate. Due to the presence of the inclined groove and the straight groove, the locking pin can be moved closer or further apart along the straight groove. When grinding the inner surface of the inner ring, the locking pins are first moved further apart, and the inner ring is placed between adjacent clamping components. Then, the locking pins are brought closer together, so that the clamping component holds the inner ring, allowing grinding of the inner surface. Similarly, when grinding the outer surface of the outer ring, the clamping component simply clamps the outer ring from its inner surface. This invention can grind either the inner or outer ring of the bearing race separately, has a wider range of applications, and reduces costs.
[0015] This utility model includes a second motor, a second threaded rod, a movable component, a second movable groove, a third motor, a grinding rod, a first rotating shaft, a second turntable, a second roller, a second rotating block, a first threaded rod, a movable block, and a fixed block. The second motor operates, controlling the rotation of the second threaded rod, which in turn controls the movement of the movable component along the second movable groove. This allows for control of the third motor and the grinding rod, changing their positions and thus controlling the radius of the grinding rod's rotation around the first rotating shaft to accommodate different positions of the bearing race. The third motor drives the grinding rod to rotate, while the first motor drives the first rotating shaft and the second turntable to rotate in both directions, causing the grinding rod to rotate around the first rotating shaft. This allows for grinding of different parts of the bearing race. After adjusting the grinding rod's rotation trajectory, rotating the second roller, the second rotating block, and the first threaded rod moves the movable block closer to the fixed block, enabling the grinding rod to grind the bearing race.

Similarly, when it is necessary to polish the outer surface of the outer ring, simply clamp the outer ring from the inner surface of the outer ring. The first rotating block 11 is fixedly connected to the end of the second rotating shaft 31 away from the first turntable 4, and the first roller 12 is fixedly connected to the side wall of the first rotating block 11.
[0030] The bearing ring grinding device provided by this utility model can grind the inner ring or the outer ring of the bearing ring separately compared with the prior art, which has a wider range of applications and reduces costs.
[0031] Please refer to another embodiment of this utility model as well. Figures 1 to 7 The side wall of the fixing block 2 is provided with a limiting groove 9. The limiting groove 9 can restrict the movement of the limiting block 10, thereby limiting the clamping member 8 and preventing the clamping member 8 from deviating during the movement. There are multiple limiting grooves 9. The side wall of the clamping member 8 is fixedly connected to the limiting block 10, and the limiting block 10 is located inside the limiting groove 9.
[0032] In another embodiment of this utility model, please refer to Figures 1 to 7The upper surface of the workbench 1 is provided with a first moving groove 13. A first threaded rod 14 is movably installed on the inner wall of the first moving groove 13. A moving block 17 is threadedly connected to the outer surface of the first threaded rod 14. A second rotating block 15 is fixedly connected to one end of the first threaded rod 14. A second roller 16 is fixedly connected to the side of the second rotating block 15 away from the first threaded rod 14. A first motor 18 is fixedly connected to the side wall of the moving block 17. When the first motor 18 is working, it will reciprocate in both forward and reverse directions to prevent the wiring of the third motor 25 from getting tangled. A first rotating shaft 19 is fixedly connected to the output end of the first motor 18. A second turntable 20 is fixedly connected to the end of the first rotating shaft 19 away from the first motor 18. An installation groove 21 is provided inside the second turntable 20. A second motor 22 is fixedly connected to the inner wall of the installation groove 21. A second threaded rod 23 is fixedly connected to the output end of the second motor 22. A moving part 24 is threadedly connected to the outer surface of the second threaded rod 23. A third motor 25 is fixedly connected to the side wall of the moving part 24. The second motor 22 operates, controlling the rotation of the second threaded rod 23, thereby controlling the movement of the moving part 24 along the second moving groove 27. This allows the third motor 25 and the grinding rod 26 to change positions, thus controlling the radius of the grinding rod 26 as it rotates around the first rotating shaft 19 to adapt to different positions of the bearing ring. The third motor 25 operates, driving the grinding rod 26 to rotate. The first motor 18 operates, driving the first rotating shaft 19 and the second turntable 20 to rotate in both directions, causing the grinding rod 26 to rotate around the first rotating shaft 19. This allows the grinding rod 26 to grind different parts of the bearing ring. After adjusting the rotation trajectory of the grinding rod 26, the second roller 16, the second rotating block 15, and the first threaded rod 14 are rotated, which can drive the moving block 17 closer to the fixed block 2, allowing the grinding rod 26 to grind the bearing ring. The output end of the third motor 25 is fixedly connected to the grinding rod 26. The second moving groove 27 is opened on the side wall of the second turntable 20, and the moving part 24 is located inside the second moving groove 27.
[0033] Please refer to another embodiment of this utility model as well. Figures 1 to 7 The lower surface of the first rotating block 11 is fixedly connected with four support legs 28. The upper surface of the workbench 1 is provided with a third moving groove 29. The inner wall of the third moving groove 29 is fixedly connected with a slide rod 30, and the outer surface of the slide rod 30 is fitted with a moving block 17.
[0034] Working principle: The clamping member 8 can grind the inner surface of the inner ring or the outer surface of the outer ring of the bearing race. By gripping and rotating the first roller 12, the first rotating block 11, the second rotating shaft 31, and the first turntable 4 rotate. Due to the presence of the inclined groove 5 and the straight groove 6, the locking pins 7 can move closer or further apart along the straight groove 6. When grinding the inner surface of the inner ring, first move the locking pins 7 further apart, placing the inner ring between adjacent clamping members 8. Then move the locking pins 7 closer together, so that the clamping members 8 clamp the inner ring, allowing for grinding of the inner surface. Similarly, when grinding the outer surface of the outer ring, simply clamp the outer ring from its inner surface. The second motor 22 operates, controlling the second threaded rod 2... 3. Rotation controls the moving part 24 to move along the second moving groove 27, thereby controlling the third motor 25 and the grinding rod 26 to change positions. This allows control over the radius of the grinding rod 26 as it rotates around the first rotating shaft 19 to adapt to different positions of the bearing ring. The third motor 25 operates, driving the grinding rod 26 to rotate. The first motor 18 operates, driving the first rotating shaft 19 and the second turntable 20 to rotate in both directions, causing the grinding rod 26 to rotate around the first rotating shaft 19. This allows for grinding of different parts of the bearing ring. After adjusting the rotation trajectory of the grinding rod 26, rotating the second roller 16, the second rotating block 15, and the first threaded rod 14 can move the moving block 17 closer to the fixed block 2, allowing the grinding rod 26 to grind the bearing ring.
