在机床夹具设计中,常常会遇到要保证工件上两条轴线(图1-a)或两个平面(图1-c),或一条轴线与一个平面(图1-b)间的一定角度关系。为了便于夹具的制造和调整,常常在夹具体上设置校验孔。
In the design of machine tool fixtures, it is often encountered that the angle between two axes (Figure 1-a) or two planes (Figure 1-c) or an angle between one axis and one plane (Figure 1-b) relationship. In order to facilitate the manufacture and adjustment of the fixture, calibration holes are often provided on the fixture body.
