摘要
正弦规作为间接测量法中常用的量具之一,是以直角三角形的正弦函数为基础,以正弦函数原理对锥度进行间接测量的一种精密测量工具,通过与量块、指示表等的配合使用,对锥体的锥度误差进行精密测量。通过介绍正弦规的结构、测量原理以及测量步骤,对测量结果的合格性与否做出判断准则。
The sine bar is the indirect measuring method used in gauging; it is on the basis of the right angled triangle sine and the sine princi- ple on the taper of indirect measurement of a precision measuring tool. By combining the gauge blocks and dial gauge, it can be used on the cone taper tolerance of precision measurement. The article mainly introduces the structure of the sine ruler, describes the measurement principle, and introduces the steps of measuring, to determine whether the measurement is qualified or not.
