[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0026] As Figures 1-4 shown, an adjustable bearing processing and fixing and grinding device includes a bottom plate 1. The right part of the top of the bottom plate 1 is fixedly connected with a fixed box 11. The top of the fixed box 11 is fixedly connected with a lifting mechanism 2. The left end of the lifting mechanism 2 is fixedly connected with an outer clamping and grinding mechanism 3. The inner wall of the bottom plate 1 is fixedly connected with an inner clamping and grinding mechanism 4. The lifting mechanism 2 includes a motor 1 21 and a mounting plate 26. The bottom end of the motor 1 21 is fixedly connected with the top of the fixed box 11. The right end of the mounting plate 26 is slidably connected with the top of the left end of the fixed box 11. The outer clamping and grinding mechanism 3 includes a fixed frame 31. The right end of the fixed frame 31 is fixedly connected with the left end of the mounting plate 26. The inner clamping and grinding mechanism 4 includes a motor 3 41. The outer wall of the motor 3 41 is fixedly connected with the inner wall of the bottom plate 1.

[0027] The bearing 5 is fixed by the inner clamping and grinding mechanism 4. Then, the height of the outer clamping and grinding mechanism 3 is changed through the lifting mechanism 2. When the height of the outer clamping and grinding mechanism 3 is appropriate, the grinding of the bearing 5 can be started. The outer clamping and grinding mechanism 3 and the inner clamping and grinding mechanism 4 cooperate with each other to complete the grinding of the inner and outer rings of the bearing 5.

[0028] As Figure 2 、 Figure 3 shown, the output end of the motor 1 21 is fixedly connected with a first threaded rod 22. The bottom end of the first threaded rod 22 is rotatably connected with the bottom end of the inner cavity of the fixed box 11. The top of the first threaded rod 22 is threadedly connected with a first slider 23. The front and rear parts of the first slider 23 are both movably sleeved with a guide rod 24. One end of the guide rod 24 is fixedly connected with one end of the inner cavity of the fixed box 11. The left end of the first slider 23 is fixedly connected with a connecting rod 25 in a linear array. The outer wall of the connecting rod 25 is slidably connected with the top of the fixed box 11. The left end of the connecting rod 25 is fixedly connected with the right end of the mounting plate 26.

[0029] By starting the first motor 21, the first threaded rod 22 is driven to rotate, causing the first slider 23 to slide on the outer wall of the first threaded rod 22. At the same time, the first slider 23 slides downward on the outer wall of the guide rod 24, driving the connecting rod 25 and the mounting plate 26 to move synchronously. The mounting plate 26 drives the outer clamping and grinding mechanism 3 to move downward synchronously. When the height of the outer clamping and grinding mechanism 3 is appropriate, the first motor 21 can be turned off, achieving the effect of changing the height.

[0030] As Figure 2 As shown, a second motor 32 is fixedly connected to the left end of the fixed frame 31. The output end of the second motor 32 is fixedly connected to a bidirectional threaded rod 33. The right end of the bidirectional threaded rod 33 is rotatably connected to the right end of the inner cavity of the fixed frame 31. The left and right parts of the outer wall of the bidirectional threaded rod 33 are both threadedly connected with second sliders 34. The outer walls of the second sliders 34 are slidably connected to the inner cavity of the fixed frame 31.

[0031] By starting the second motor 32, the bidirectional threaded rod 33 is driven to rotate, causing the second sliders 34 to slide on the outer wall of the bidirectional threaded rod 33.

[0032] As Figure 2 As shown, an arc-shaped block 35 is fixedly connected to the bottom end of the second slider 34. A first grinding sandpaper 36 is fixedly connected to the outer wall of the arc-shaped block 35.

[0033] When the second slider 34 moves, it drives the arc-shaped block 35 to move synchronously. The arc-shaped block 35 drives the first grinding sandpaper 36 to move synchronously, making the outer wall of the first grinding sandpaper 36 contact the outer wall of the bearing 5. It is only limited to contact and cannot be tightened. Then, grinding can be started.

[0034] As Figure 2 、 Figure 4 As shown, the output end of the third motor 41 is fixedly connected to a rotating shaft 42. A fixed ring 421 is fixedly connected to the bottom of the rotating shaft 42. A second threaded rod 43 is movably sleeved on the top of the rotating shaft 42. A movable ring 431 is threadedly connected to the outer wall of the second threaded rod 43. The top end of the rotating shaft 42 is lapped with a limiting plate 44. The bottom end of the limiting plate 44 is lapped with the top end of the second threaded rod 43. A bolt 441 is threadedly connected to the inner wall of the limiting plate 44. The outer wall of the bolt 441 is threadedly connected to the inner wall of the rotating shaft 42. The center point of the rotating shaft 42 and the center point of the arc-shaped block 35 are located on the same vertical line.

[0035] By rotating the second threaded rod 43, the movable ring 431 slides downward on the outer wall of the second threaded rod 43. While rotating the second threaded rod 43, the limiting plate 44 limits the second threaded rod 43 to prevent the second threaded rod 43 from disengaging from the rotating shaft 42.

[0036] As Figure 2 、 Figure 4As shown, the outer wall of the fixed ring 421 is rotatably connected with the first movable rod 45 in a circular array, the outer wall of the movable ring 431 is rotatably connected with the second movable rod 46 in a circular array, the middle parts of the first movable rod 45 and the second movable rod 46 are rotatably connected, one end of the second movable rod 46 is rotatably connected with a connecting plate 47, the outer wall of the connecting plate 47 is fixedly connected with a second polishing sandpaper 48, the outer wall of the second polishing sandpaper 48 is lapped with a bearing 5, the top end of the first movable rod 45 is fixedly connected with a sliding rod 451, and the outer wall of the sliding rod 451 is slidably connected with the top of the connecting plate 47.

[0037] When the movable ring 431 slides, it drives the second movable rod 46 to rotate. The second movable rod 46 drives the first movable rod 45 to rotate synchronously, so that the first movable rod 45 drives the sliding rod 451 to slide on the inner wall of the connecting plate 47. Thus, the connecting plate 47 drives the second polishing sandpaper 48 to approach the inner wall of the bearing 5. When the outer wall of the second polishing sandpaper 48 is in tight contact with the inner wall of the bearing 5, the rotation of the second threaded rod 43 can be stopped, thereby fixing the bearing 5, achieving a fixing effect. Then, the third motor 41 is started to drive the bearing 5 to rotate synchronously. When the bearing 5 rotates, the first polishing sandpaper 36 polishes the outer wall of the bearing 5. When the polishing of the outer wall of the bearing 5 is completed, the third motor 41 can be turned off. Then, the second motor 32 is restarted to make the outer wall of the first polishing sandpaper 36 in tight contact with the outer wall of the bearing 5, thereby clamping and fixing the bearing 5 with the first polishing sandpaper 36. Then, the second threaded rod 43 is rotated reversely so that the outer wall of the second polishing sandpaper 48 is no longer in tight contact with the inner wall of the bearing 5, but the outer wall of the second polishing sandpaper 48 still contacts the inner wall of the bearing 5. Subsequently, the third motor 41 can be started, and the third motor 41 drives the second polishing sandpaper 48 to rotate, and the second polishing sandpaper 48 polishes the inner wall of the bearing 5, thus completing the polishing of the inner and outer rings of the bearing 5, achieving a polishing effect.

[0038] Working principle of the utility model: During use, first bring the inner wall of the bearing 5 into contact with the outer wall of the second polishing sandpaper 48, and then rotate the second threaded rod 43 to make the movable ring 431 slide on the outer wall of the second threaded rod 43, thereby driving the second movable rod 46 to rotate. The second movable rod 46 drives the first movable rod 45 to rotate synchronously, causing the first movable rod 45 to drive the sliding rod 451 to slide inside the connecting plate 47. Thus, the connecting plate 47 drives the second polishing sandpaper 48 to approach the inner wall of the bearing 5. When the outer wall of the second polishing sandpaper 48 is in tight contact with the inner wall of the bearing 5, stop rotating the second threaded rod 43, thereby fixing the bearing 5, achieving a fixing effect. Then start the first motor 21 to drive the first threaded rod 22 to rotate, making the first slider 23 slide on the outer wall of the first threaded rod 22. At the same time, the first slider 23 slides downward on the outer wall of the guide rod 24, driving the connecting rod 25 and the mounting plate 26 to move synchronously. The mounting plate 26 drives the outer clamping and polishing mechanism 3 to move downward synchronously. When the height of the outer clamping and polishing mechanism 3 is appropriate, turn off the first motor 21, achieving an effect of changing the height. Subsequently, the device can be adjusted according to the size of the outer ring of the bearing 5. Start the second motor 32 to drive the bidirectional threaded rod 33 to rotate, making the second slider 34 slide on the outer wall of the bidirectional threaded rod 33. The second slider 34 drives the arc-shaped block 35 to move synchronously, and the arc-shaped block 35 drives the first polishing sandpaper 36 to move synchronously, bringing the outer wall of the first polishing sandpaper 36 into contact with the outer wall of the bearing 5, only for contact and not for tightness. When adjusted, start the third motor 41 to drive the rotating shaft 42 to rotate, making the rotating shaft 42 drive the fixed ring 421 to rotate synchronously. The fixed ring 421 drives the first movable rod 45 to rotate synchronously, and the first movable rod 45 drives the connecting plate 47 to rotate synchronously. Thus, the connecting plate 47 drives the bearing 5 to rotate synchronously. When the bearing 5 rotates, the outer wall of the bearing 5 is polished by the first polishing sandpaper 36. When the outer wall of the bearing 5 is polished, turn off the third motor 41. Then restart the second motor 32 to make the outer wall of the first polishing sandpaper 36 in tight contact with the outer wall of the bearing 5, thereby clamping and fixing the bearing 5 with the first polishing sandpaper 36. Then rotate the second threaded rod 43 in the reverse direction so that the outer wall of the second polishing sandpaper 48 is no longer in tight contact with the inner wall of the bearing 5, but the outer wall of the second polishing sandpaper 48 still contacts the inner wall of the bearing 5. Subsequently, start the third motor 41, and the third motor 41 drives the second polishing sandpaper 48 to rotate, and the inner wall of the bearing 5 is polished by the second polishing sandpaper 48. Thus, the polishing of the inner and outer rings of the bearing 5 is completed, achieving a polishing effect, thereby greatly improving the user experience.
