Problems solved by technology

[0002] In the field of mechanical processing, there are generally special inspection tools for the detection of workpiece machining accuracy. For example, the inner or outer diameter and length of the workpiece can be measured by vernier calipers. However, for workpieces with hemispherical ends, if you want to detect The machining accuracy of the hemispherical end can no longer meet the needs if general measuring tools such as vernier calipers are used

Abstract

The invention relates to a using method of a spherical surface precision detection device. The method comprises the following steps that firstly, a locating barrel is fixed; secondly, a detection gauge is inserted in a through hole of the locating barrel; thirdly, a hemispherical end of a workpiece is placed in a hemispherical groove of the locating barrel; fourthly, a gauge rod of the detection gauge is clamped through locating screws; fifthly, a gauge point of the detection gauge is made to make contact with different positions of the spherical surface of the hemispherical end of the workpiece, and whether the spherical surface machining precision of the hemispherical end of the workpiece meets demands is judged. The spherical surface precision detection device is simple in structure, convenient to operate and high in reliability and detection precision.

Description

technical field [0001] The invention relates to the technical field of inspection tools, in particular to a method for using a detection device for the accuracy of a spherical end of a workpiece. Background technique [0002] In the field of mechanical processing, there are generally special inspection tools for the detection of workpiece machining accuracy. For example, the inner or outer diameter and length of the workpiece can be measured by vernier calipers. However, for workpieces with hemispherical ends, if you want to detect The processing accuracy of the hemispherical end can no longer meet the needs if general measuring tools such as vernier calipers are used. Contents of the invention [0003] The present invention aims at the above-mentioned problems in the prior art, and provides a method for using a spherical precision detection device, which has a simple structure, easy operation, high reliability and high detection accuracy. [0004] The technical scheme ad...
