Polishing device for bearing machining and production

The utility model relates to the technical field of bearing production, in particular to a polishing device for bearing processing and production, which comprises a door-shaped frame, a horizontal circular fixing table is arranged in an inner cavity of the door-shaped frame, a plurality of vertically through sliding chutes are uniformly and annularly arranged around the center of the fixing table, and the sliding chutes are arranged along the radial direction of the fixing table. Each sliding groove is slidably connected with a sliding stand column in the length direction of the sliding groove. All the sliding stand columns are driven by the driving mechanism to synchronously move outwards to fix a workpiece, at the moment, the outer side face of the workpiece is exposed, and therefore the polishing mechanism can polish the outer side face of the workpiece; all the sliding stand columns are driven by the driving mechanism to synchronously move inwards to fix the workpiece, at the moment, the inner side face o
