Bearing inner ring grinding device

The invention discloses a bearing inner ring grinding device, and relates to the technical field of accessory machining equipment. The upper end of a wire cylinder seat is fixedly provided with a first connecting plate, a second connecting plate is fixedly mounted at the upper end of a bottom plate and located on the outer side of a bearing seat, and a clamping plate is fixedly mounted at each of the adjacent ends of the first connecting plate and the second connecting plate. The clamping of a bearing can be achieved when the device is used, deviation in the grinding process is avoided, the grinding accuracy is further improved, and the clamping stability is guaranteed. The power driving end of a flat motor is fixedly connected with a pressing plate, symmetrical grinding heads are fixedly installed at the two ends of the pressing plate, and a plurality of groups of equidistant adjusting holes are formed in the middle of the interior of the pressing plate, so that the distance between the two grinding heads ca
