随着现代工业生产的发展,产品更新换代频繁。现已有越来越多的新产品零件,在机械加工中采用组合夹具进行生产。本文结合我厂使用情况,介绍组合夹具的一些组装特点。一、组合夹其和专用夹具的区别组装组合夹具和设计专用夹具有相同之处,也有不同之处。它们都须考虑对工件六个自由度的限制,或根据需要,限制其中几个自由度;都要进行工件公差和尺寸链的分析及夹具工艺尺寸计算:都要考虑工件
With the development of modern industrial production, product replacement frequently. More and more new product parts are now available, which are manufactured using a combination of fixtures in machining. This article combined with the use of our factory, introduce some assembly features of the combination of fixtures. First, the difference between the combination of folders and special fixture Assembly combination fixture and design special folder has the same, there are differences. They all have to consider the six degrees of freedom of the workpiece, or limit several of them as needed; both the workpiece tolerance and the dimensioning chain are analyzed and the fixture size is calculated: both the workpiece
