[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearing rings are annular parts of radial rolling bearings with one or several raceways. When processing them, fixtures are needed to fix the bearing rings.

[0003] However, in the existing equipment, the method of clamping the outside of the bearing ring by pushing the clamping plate with a hydraulic cylinder is very likely to cause the bearing ring to deform due to excessive squeezing during clamping, thereby reducing the quality of the bearing. For this reason, a clamping mechanism for the bearing ring is proposed. Utility Model Content
