[0041] Furthermore, the surface of the driving roller 4-5 is a rubber layer with an anti-slip structure.

[0042] In this embodiment, the rubber layer with an anti-skid structure can ensure that the driving roller 4-5 will not slip when the roller bearing is driven to rotate after being fitted with the bearing.

[0043] Furthermore, the rotation direction of the grinding roller 5 - 4 is opposite to the rotation direction of the bearing.

[0044] In this embodiment, foreign matter on the surface can be cleaned off by rotating the grinding roller 5 - 4 in the opposite direction.

[0045] Furthermore, the distance between the pair of grinding rollers 5 - 4 is the same as the thickness of the bearing.

[0046] In this embodiment, the grinding roller 5-4 can grind both inner and outer end surfaces of the bearing at the same time by having the same size as the thickness of the bearing.

[0047] When grinding is required, the workpiece is sleeved on the outside of the driving roller 4-5 and the inner support roller 4-6, and then the telescopic cylinder 4-1 is started to push the driving roller 4-5 and the inner support roller 4-6 to clamp the bearing. At the same time, the internal support wheel 4-11 will be supported on the inside of the bearing, and the elastic force of the spring 4-10 will support the inner auxiliary bearing to rotate. The other end of the bearing is sleeved between the two grinding rollers 5-4, and then the driving motor 4-4 and the second motor 5-3 are started, so that the inner and outer end faces of the bearing are grinded by the grinding roller 5-4 in a rotating state. During the grinding process, the dust collection device 2 is kept running to make the dust collection mesh 6-4 and the long hole 6-2 generate suction to absorb the dust during grinding. After completion, the bearing can be removed. If the bearing size is different, the mounting seat 5-1 can be removed and the corresponding grinding roller 5-4 can be replaced.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
