引言 机床装配尺寸链的基本理论,就在于以事物是普遍联系相互制约的观点来研究机床各另件间的相互关系(尺寸关系、表面相互位置关系等等),从而求得保证机床装配精度的最经济合理的办法。 我国第一个五年计划许多新产品的试制过程中,已经普遍遇到这一项技术理论问题。在第二个五计划中绝大多数产品均将由自己独立设计,所有的设计师工艺师及装配工人同志们大家都掌握尺寸链的基本理论,并在生产实用便有非常具大的意义。近几年来沈阳各机械制造厂经常要求我院协助解决有关尺寸链的理论及实际应用的具体
Introduction The basic theory of machine tool assembly dimension chain is to study the relationship between the various parts of the machine tool (dimensional relationship, surface mutual positional relationship, etc.) from the point of view that things are universally linked to each other, so as to ensure the accuracy of the machine tool assembly The most economical and reasonable way. During the trial production of many new products in China’s first five-year plan, this issue of technical theory has generally been encountered. Most of the products in the second Five-Plan will be designed by ourselves. All the designers, technicians and assembler comrades master the basic theory of the dimension chain and are of great significance in practical production. In recent years, Shenyang machinery factory often asked our hospital to help solve the theory of the size chain and the practical application of the specific
