A hydraulic rod 25 for adjusting the height of the lifting plate 22 is fixedly installed at the top of the lifting frame 21;

[0024] During the use by the staff, the bearing ring to be polished is clamped and limited by the three-jaw chuck 41. The hydraulic rod 25 starts to work, driving the lifting plate 22 to move downward. The lifting plate 22 drives the lifting block to move downward inside the lifting groove 26, so that the adjusting assembly 30 moves to a suitable position, thus facilitating the device to process workpieces of different heights.

[0025] The adjusting assembly 30 includes a first threaded rod 31 rotatably disposed inside the mounting frame 23. A moving block 32 is threadedly disposed on the surface of the first threaded rod 31. A moving groove 33 for the front-back sliding of the moving block 32 is formed inside the first threaded rod 31.

A moving block 36 is threadedly disposed on the surface of the second threaded rod 35. An external polishing head 37 adapted to the internal polishing head 34 is fixedly installed at the bottom of the moving block 36;

[0026] Manually rotate the first knob 38 to drive the rotation of the first threaded rod 31. The first threaded rod 31 drives the moving block 32 to move inside the moving groove 33. The moving block 32 drives the surface of the internal polishing head 34 to fit against the inner side wall of the bearing ring. Then manually rotate the second knob 39 to drive the moving block 36 to move towards the center through the second threaded rod 35. The moving block 36 drives the external polishing head 37 to fit against the outer side wall of the bearing ring. The first motor 24 starts to work, driving the rotation of the mounting frame 23. The mounting frame 23 drives the internal polishing head 34 and the external polishing head 37 to polish the outer and inner rings of the bearing ring simultaneously.

[0027] Lifting blocks are fixedly installed on both the left and right sides of the lifting plate 22. Lifting grooves 26 for the up-and-down sliding of the lifting blocks are formed inside the lifting frame 21.

[0028] A first knob 38 for driving the rotation of the first threaded rod 31 is rotatably disposed on the surface of the mounting frame 23. A second knob 39 for driving the rotation of the second threaded rod 35 is rotatably disposed on the surface of the internal polishing head 34.

A first sheave 42 for driving the rotation of the three-jaw chuck 41 is rotatably disposed at the bottom of the base 10. A second sheave 43 is disposed on the right side of the first sheave 42;

[0030] The second motor 44 starts to work. Through the action of the first sheave 42 and the second sheave 43, it drives the three-jaw chuck 41 to rotate in the opposite direction to the mounting bracket 23, so that the clamped bearing ring rotates in the opposite direction to the inner polishing head 34 and the outer polishing head 37, thereby accelerating the polishing efficiency of the device. At the same time, the dust suction device 50 sucks up the generated waste chips through the dust suction pipe and the dust suction hood 60.

[0031] A belt is sleeved on the outer edges of the first sheave 42 and the second sheave 43 together. The first sheave 42 and the second sheave 43 are connected by belt drive. A second motor 44 for driving the second sheave 43 to rotate is fixedly installed at the bottom of the base 10.

[0032] A support block is fixedly installed on the left side of the lifting frame 21. A dust suction device 50 is fixedly installed on the top of the support block. A dust suction pipe is communicated with the top of the dust suction device 50. A dust suction hood 60 is fixedly installed near the left side at the bottom of the lifting plate 22. The right end of the dust suction pipe sequentially penetrates through the inside of the lifting frame 21 and the lifting plate 22, and is communicated with the top end of the dust suction hood 60.

[0033] The working principle of the bearing ring polishing device convenient for cleaning provided by the present utility model is as follows:

[0034] The first step: During the use by the staff, the bearing ring to be polished is clamped and limited by the three-jaw chuck 41. The hydraulic rod 25 starts to work, drives the lifting plate 22 to move downward. The lifting plate 22 drives the lifting block to move downward inside the lifting groove 26, so that the adjusting assembly 30 moves to a suitable position, thereby facilitating the device to process workpieces of different heights.

[0035] The second step: Manually rotate the first knob 38 to drive the first threaded rod 31 to rotate. The first threaded rod 31 drives the moving block 32 to move inside the moving groove 33. The moving block 32 drives the surface of the inner polishing head 34 to fit against the inner wall of the bearing ring. Then manually rotate the second knob 39. Through the second threaded rod 35, the movable block 36 is driven to move towards the center. The movable block 36 drives the outer polishing head 37 to fit against the outer wall of the bearing ring. The first motor 24 starts to work, drives the mounting bracket 23 to rotate. The mounting bracket 23 drives the inner polishing head 34 and the outer polishing head 37 to polish the outer ring and the inner ring of the bearing ring simultaneously.

[0036] The third step: The second motor 44 starts to work. Through the action of the first sheave 42 and the second sheave 43, it drives the three-jaw chuck 41 to rotate in the opposite direction to the mounting bracket 23, so that the clamped bearing ring rotates in the opposite direction to the inner polishing head 34 and the outer polishing head 37, thereby accelerating the polishing efficiency of the device. At the same time, the dust suction device 50 sucks up the generated waste chips through the dust suction pipe and the dust suction hood 60.

[0037] Compared with the related technologies, the bearing ring polishing device provided by the utility model which is convenient for cleaning has the following beneficial effects:

[0038] Through the mutual cooperation of the various components of the device, turning the first knob 38 drives the first threaded rod 31 to rotate. The first threaded rod 31 drives the moving block 32 to move inside the moving groove 33. The moving block 32 drives the surface of the inner polishing head 34 to fit against the inner side wall of the bearing ring. Then, manually turning the second knob 39 drives the movable block 36 to move towards the center. The movable block 36 drives the outer polishing head 37 to fit against the outer side wall of the bearing ring. The first motor 24 starts to work, driving the mounting bracket 23 to rotate.
