[0002] Coaxiality refers to the condition in which the measured axis on the part remains in the same straight line relative to the reference axis. It is convenient for detecting whether the coaxiality between the stopper and the inner bore of the motor base is consistent. The stopper is where the motor base is installed with the end cover or flange, and the inner bore is the inside of the motor base. By detecting whether the coaxiality of the stopper and the inner bore of the motor base is consistent, it is convenient to reduce the probability of unstable motor rotation caused by inconsistent coaxiality between the stopper and the inner bore.

When the detection personnel are relatively tired, the hand-holding mounting plate is easily unstable, causing the positioning pin and the dial indicator to be not located in the same horizontal plane, and causing the dial indicator to tilt, resulting in a large error in the detected coaxiality. In view of this, a motor base coaxiality detection device is provided to overcome the above-mentioned defects. Utility Model Content
