一、动力头的用途本动力头(图1)是圆柱凸轮进给滑套移动式的小型机械动力头,用于配置组合机床及其自动线,完成钻孔、扩孔、铰孔、倒角和攻丝等工序。配置铣削主轴箱也可以完成小平面或槽的铣削加工。可以单轴使用,也可以装上多轴主轴箱,用于多轴加工。本动力头可以根据被加工零件的要求,按照所选择的工作循环设计圆柱凸轮曲线。在一般情况下,该动力头可实现下列工作循环:1.一次工作进给循环:快速前进→工作进给→快速退回。2.二次工作进给循环:快速前
First, the use of power head The power head (Figure 1) is a cylindrical cam feed sleeve mobile small mechanical power head, used to configure the combination of machine tools and automatic line, complete drilling, reaming, reaming, chamfering and Tapping and other processes. Configuring the milling headstock can also complete faceting or grooving. Can be used single-axis, multi-spindle headstock can also be installed for multi-axis machining. The power head can be machined parts according to the requirements of the selected work cycle design cylindrical cam curve. Under normal circumstances, the power head can achieve the following work cycle: 1. A working feed cycle: fast forward → work feed → rapid return. 2 secondary feed cycle: fast before
