在机械修配中,往往会遇到一些只能夹持其锥体部位来进行机械加工的工件,这样装夹就比较困难,成了很棘手的问题。 通常装夹方法是先测出工件的锥度,配作一个锥套,将工件套入压紧后,装在四爪卡盘上进行加工。这种方法比较麻烦,对于单个工件尤其不适宜。 我们采用了一种新方法:即用四块半圆球铜垫,分别垫在四爪卡盘上,如图1所示,这样装夹既牢固,又 In the mechanical repair, often encounter some can only hold the cone part of the workpiece for machining, so the clamping is more difficult, has become a very difficult issue. Usually clamping method is to first measure the taper of the workpiece, equipped with a tapered sleeve, the workpiece set into the compression, mounted on a four-jaw chuck for processing. This method is cumbersome and especially unsuitable for a single workpiece. We have adopted a new method: that is, with four semicircular ball copper pads, respectively pad on the four jaw chuck, as shown in Figure 1, so that the clip is both solid, and
