图1所示转轴是HZ10组合开关的一个零件。材料为冷拉圆钢,具有一定的尺寸精度和形位精度要求。最初,我们采用V形块定位,凸轮夹紧机构来加工。由于定位精度不高,也不便于互换和调整,通用性差等问题,影响了加工质量和生产效率,为此,我们重新设计了一套弹性定心夹具,见图2。经生产使用,该夹具加工质量比较稳定,对于不同尺寸的零件只要更换一个弹性套筒即可,具有一定的实用性和经济效果。现简单介绍如下。
The shaft shown in Figure 1 is a part of the HZ10 combination switch. Material for the cold drawn round steel, with a certain degree of dimensional accuracy and shape accuracy requirements. Initially, we used V-block positioning, cam clamping mechanism to process. Due to the poor positioning accuracy, inconvenient interchangeability and adjustment, poor universality and other issues, which affect the processing quality and production efficiency, we have redesigned a set of elastic centering fixtures, as shown in Figure 2. The production and use of the fixture processing quality is relatively stable, for different sizes of parts as long as the replacement of a flexible sleeve can have some practicality and economic effects. Now brief introduction is as follows.
