我厂加工阀体如图1所示,阀体需加工两端φ14mm两斜孔,两端斜孔角度又不一样,一端为30°,另一端为15°。过去在立铣上根据零件斜度要求利用旋转立铣头主轴加工,这样,操作麻烦、加工效率低。为此,我们设计了如图2所示的钻夹具。 I process the valve body shown in Figure 1, the body needs to be processed at both ends φ14mm two oblique hole, oblique angle at both ends are not the same, one end of 30 °, the other end of 15 °. In the past, according to the requirement of the part pitch, it is required to make use of the rotary milling head spindle in the vertical milling. In this way, the operation is troublesome and the processing efficiency is low. To this end, we designed a drill as shown in Figure 2.
