Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of roll bearing polishing technology, in particular to a positioning structure for roll bearing polishing. BACKGROUND

[0002] The existing roll bearing is polished smooth on the surface of the bearing ring in the processing process, thereby reducing the friction between the bearing and the ball.

[0003] At present, the Chinese utility model with the publication number CN219967341U discloses a positioning structure for roll bearing polishing. The existing positioning structure for roll bearing polishing mainly adopts the mode of clamping the two sides of the bearing surface for positioning, but in the actual polishing process of the roll bearing, the inner surface and the outer surface need to be polished separately, so after the two sides of the bearing ring surface are clamped by the clamping plate, only the inner surface can be polished, and the outer surface cannot be directly polished because it is blocked by the clamping plate. After the inner surface is polished, the bearing ring inner surface can be supported by replacing the clamp, and the outer surface can be polished, so that different clamps need to be replaced for clamping and positioning during the polishing process of the roll bearing, which affects the polishing processing efficiency of the roll bearing.
