Abstract
The invention relates to a detection tool for detecting the coaxiality of a motor housing, which comprises a frame plate. The plate surface of one side of the frame plate is adopted as a fundamental plane. The fundamental plane is adhered to the end surface of a to-be-detected motor housing. The fundamental plane of the frame plate is protruding and extending to be laterally provided with a positioning part in a direction away from the fundamental plane. The positioning part is tangent to the front-edge hole wall of the to-be-detected motor housing to abut against the front-edge hole wall. The frame plate also is provided with an indicating gauge. The detection end of the indicating gauge abuts against the hole cavity wall of the front edge of the motor housing. The normal direction of the abutted part of the positioning part against the front-edge hole wall is parallel to the normal direction of the abutted part of the detection end of the indicating gauge against the hole cavity wall of the motor housing. The detection tool can be used for conveniently measuring the coaxiality of motor housings of different models and is high in detection accuracy.
