一、前言一面双销定位法是夹具中最常用的定位方法,对于双销的设计计算(主要是菱形销的设计计算)通常是认为菱形销削边之后即能补偿孔心距及销心距的制造误差,因而将菱形销圆柱部分和工件孔的配合设计成与圆柱销和工件孔的配合一样,或是简单地凭经验选取 g_6、f_7、e_8、d_8、结果常常造成工件装 First, the preface Side pin positioning method is the most common fixture in the positioning method for the two-pin design calculations (mainly the diamond pin design calculation) is usually considered diamond-edged cutting edge that is to compensate for the pitch and pin pitch Of the manufacturing error, so the diamond-shaped cylindrical part and the workpiece hole with the design of the cylinder pin and the workpiece hole with the same, or simply selected empirically g_6, f_7, e_8, d_8, the result is often caused by the workpiece
