[0002] In lathe machining, there are a large number of parts with conical and stepped parts, and after the machining of the parts is completed, the diameters of the conical surfaces of the machined parts with conical and stepped parts often need to be detected.

[0003] At present, there is no special gauge for detecting the diameter of the conical surface of the workpiece, and most of the detection is carried out by clamping the outer wall of the workpiece with a vernier caliper. During the detection process, manual holding is required. Since the weighing surface is a conical surface, the actual clamping position of the vernier caliper may deviate from the theoretical clamping position during manual detection, resulting in a large error between the measured value and the theoretical value, and affecting the accuracy of the workpiece measurement.
