Abstract

The invention discloses a detecting tool for detecting center hole depth of a motor shaft end surface. The detecting tool comprises a base plate, a supporting rod, an adjusting plate, a workpiece clamping mechanism, an elastic pressing head, a supporting block and a lever indicating gauge. The supporting block is installed on the base plate, and an axis of the supporting block, an axis of a motor shaft and a center of the elastic pressing head are on a straight line. The detecting tool is simple in structure, easy to use, avoids various accumulative errors and is high in accuracy, so that consistency of the center hole depth is ensured. The detecting tool is used for detecting the center hole depth of the motor shaft, lays a good foundation for subsequent finish machining positioned through the center hole, and is suitable for detection in mass production.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a quick inspection tool for detecting the depth of a central hole on an end face of a motor shaft. Background technique [0002] In modern processing technology, all the finishing of the motor shaft is based on the center hole, so the accuracy of the depth dimension of the center hole directly affects the machining accuracy of the motor shaft. With the continuous development of motor application technology, the accuracy requirements for the motor shaft Gradually improve. Thereby directly affecting the processing efficiency and the quality of the finished product. [0003] The existing measurement method is to use a vernier caliper with a steel ball to detect the depth of the center hole of the shaft end. This kind of measurement can penetrate the depth of the center hole and express it by measuring the horizontal displacement. , resulting in large detection errors...
