Precise bearing inner diameter detection machine

The utility model provides a precision bearing inner diameter detection machine, belongs to the technical field of bearing processing, and aims to solve the problems that when many bearings are detected in the prior art, a worker needs to continuously twist the bearings for detection, and the operation is tedious. Comprising a detection base, a lifting base, a lifting sliding plate, a detection support block, a detection main body, a probe connecting block, a detection lifting mechanism and a detection rotating mechanism, the lifting base is fixedly connected to the upper end surface of the detection base; the lifting sliding plate is connected into the lifting base in a sliding mode. The detection supporting block is fixedly connected to the front end face of the lifting sliding plate. The detection main body is fixedly connected to the left end surface of the detection support block; the probe connecting block is in threaded connection with the right end surface of the detection support block; the detection
