摘要
研究一种测量梯形螺纹中径的二针测量法,与传统的三针测量法相比,具有能测量大直径螺纹和对操 作空间适应性强等优点.该方法也适用于普通螺纹.
This paper describes a two-needle method for measuring middle diameter of metric trapezoidal screw threads. Compared with the conventional three-needle method, this method has some advantages such as being able to measure large diameter threads and its adaptability to operational space. This method is also suitable for measuring general purpose screw threads.
