Abstract

The invention relates to a method for measuring a device for measuring inner and outer diameters of cylindrical parts. The device for measuring inner and outer diameters of cylindrical parts includes a base plate, a column vertically arranged on the base plate, a vertical movement assembly arranged on the column, and a The rotating assembly on the bottom plate, the workpiece fixture arranged on the rotating assembly, the measuring assembly arranged on the vertical motion assembly, the direct-drive linear motor, and the high-precision displacement sensor. The direct-drive linear motor drives the vertical motion assembly. The invention effectively reduces the influence of the eccentricity error of the columnar part on the measurement result of the inner and outer diameter in the clamping process; reduces the influence of the cylindricity of the part positioning surface and the coaxiality error of the part positioning surface and the measured surface on the measurement result of the inner and outer diameter of the cylindrical part; While ensuring the measurement efficiency, the non-contact measurement does not cause any interference or damage to the measured surface; and improves the measurement accuracy of the inner and outer diameters of cylindrical parts to the sub-micron level.

Description

technical field [0001] The invention relates to the field of inner and outer diameter detection, in particular to a measuring method for a device for measuring inner and outer diameters of cylindrical parts. Background technique [0002] At present, the measurement of the inner and outer diameters of cylindrical parts mainly uses the method of plug gauge (through gauge, stop gauge) and the method of using a three-coordinate measuring machine. When using the plug gauge, the go gauge and the stop gauge are used together. When the go gauge can pass the measured object but the stop gauge cannot, it proves that the size of the measured object is between the go gauge and the stop gauge. The three-coordinate measuring machine is a general-purpose measuring device. It can also be used to measure linear, plane, and position features in addition to cylindrical features. When measuring a cylindrical surface, the measuring head senses position information by touching different points on...
