一、动力头的用途本动力头(图1)是平板凸轮进给滑套移动式的小型机械钻孔动力头。与1HT4141、1HT4151型机械动力头的主要区别是:结构简化,比前者少用两个电磁离合器,并且采用了平板凸轮。在工作性能上的差别是,其主轴的主运动(主轴回转)和进给运动不能分开,即每次工作循环完毕,主轴退回原位后,必须切断电机停止回转,下次工作循环需重新起动电机。动力头的用途和1HT4141、1HT4151型相同。
First, the use of power head The power head (Figure 1) is a flat cam feed sleeve mobile small mechanical drilling power head. And 1HT4141, 1HT4151 mechanical power head The main difference is: the structure is simplified, less than the former two electromagnetic clutch, and the use of flat cam. The difference in performance is that the spindle’s main motion (spindle rotation) and feed motion can not be separated. That is, after each working cycle is finished, the spindle must be cut off to stop rotating after the spindle is returned to its original position, and the next working cycle needs to be restarted Motor. The use of power head and 1HT4141, 1HT4151 type the same.
