摘要：

为了解决螺纹量规检定过程中不能完全覆盖各种螺纹形式的实际问题,根据螺纹检定的三针法及双球法通用原理,应用马尔测长机及其附件,以双球法检测螺纹环规的单一中径为例,详细阐述其测量步骤及注意要点,并对此过程进行不确定度分析评定。实验表明此种检测方法能够满足螺纹环规的正常使用要求,具有测量精度高,操作方便,可信度高特点,为螺纹环规的实际使用提供依据。

Abstract: To solve the problem of that thread gauge verification can not cover all kinds form of the thread gauge,the author measured the pitch diameter of thread ring gauge with mahr length measuring machine and its accessories in "double sphere" method,giving particular steps and notices of measurement by the basic theory of "three-wire" and "double sphere" method.At same time the uncertainty of this method has been evaluated.The experiment indicated that it can meet the requirement of general using of thread ring gauge,having the characteristics of "high measuring precision,convenient operating and high reliability" etc.
