摘　　要：在各种现代装备系统的设计和制造工作中,对锥体螺纹塞规的加工提出了更高的要求,如何提高锥体螺纹塞规的测量准确度成为亟需解决的课题。目前锥体螺纹塞规主要是测量其基面中径,且方法不同结果有差异。文中以NPT型螺纹塞规为例,总结出其多参数的测量方法。With the development of modern industry, put forward higher requirement for processing precision of taper thread plug gauge, how to improve the measurement of taper thread plug gauge accuracy has become an important issue that must be addressed. At present, the cone thread plug gauge is mainly to measure the base diameter and different methods lead to different results. According to the definition and design principle of taper thread plug gauge. summarized the measurement methods of comprehensive parameters of cone thread plug gauge. It is focused on Method of measuring basic parameters. Through geometric analysis and theoretical derivation, make sure that calculation formula and measurement method of the cone thread plug gauge parameters.
