Rotary clamping device for bearing ring

The invention discloses a bearing ring rotating and clamping device which comprises a ferrule detection station, three bases, a first guide rail arranged above the bases, a driving box arranged on one base, a transmission box, two fixed rotating and clamping mechanisms, a movable rotating and clamping mechanism and three sets of overturning and pressing mechanisms. The three bases are circularly distributed on the outer side of the center of the detection station, the transmission case is located in the center area of the detection station, and the two fixed rotary clamping mechanisms and the movable rotary clamping mechanism are connected with the first guide rails in a sliding mode respectively. According to the rotary clamping device for the bearing ring, the driving force of one group of driving pieces is transmitted to the three groups of rotary clamping mechanisms through the transmission mechanism, so that the three groups of rotary clamping mechanisms can synchronously clamp and rotate a workpiece, th
