工件在夹具中的安装,包括定位和夹紧两个过程。工件定位的目的,就是要使同一批工件在夹具中占有一致的正确加工位置。所以,工件在夹具中的定位,是夹具设计中首先要解决的重要问题。一、过定位及其合理应用如果工件的某个自由度被限制了两次或两次以上,则叫做过定位。对于过定位是否允许,应根据具体情况具体分析。一般情况下,应该避免使用过定位,
Workpieces in the fixture installation, including positioning and clamping of the two processes. The purpose of positioning the workpiece, is to make the same batch of workpieces in the fixture occupy the same correct processing position. Therefore, the positioning of the workpiece in the fixture, fixture design is the first important issue to be solved. First, over positioning and its reasonable application If a degree of freedom of the workpiece is limited to two or more times, then called positioning. For over positioning is allowed, should be based on the specific circumstances of the specific analysis. Under normal circumstances, should avoid the use of positioning,
