Bearing ring polishing equipment

The invention relates to bearing ring grinding equipment which comprises a workbench mechanism, a grinding mechanism and a grinding mechanism. The grinding mechanism is mounted on the stand column in a lifting manner; the fixing mechanism is fixedly mounted on the rotating table and can rotate along with the rotating table; wherein the fixing mechanism comprises a central shaft motor coaxially installed with the rotating table, a driving bevel gear is installed on an output shaft of the central shaft motor, the driving bevel gear is connected with a plurality of driven bevel gears in an engaged mode, each driven bevel gear is connected with a lead screw connecting rod with the same size, and the tail end of each lead screw connecting rod is provided with a clamping piece for fixing the bearing ring. The device can be suitable for shaft sleeve rings of various specifications, the bearing ring is fixed, the concentricity in the clamping process is guaranteed, and therefore the grinding precision of the bearing
