在原来钻床进刀箱的侧面,伸出一个轴,轴上装进刀凸轮6和气阀凸轮7。同时在床身上固定有支座5和支架4。摇杆17的一端用销子与支架4铰链联接,另一端则装有与进刀凸轮6相接的滚轮9,所以,进刀凸轮6在回转时推动滚轮9。滚轮9和摇杆17一起绕O_1回转,这样就拨动主轴上的销钉1与主轴一同作自动进刀运动。这时夹紧工件的运动由气阀凸轮7,使活
In the original drilling machine into the side of the box, out of a shaft, shaft into the knife cam 6 and valve cam 7. At the same time, a support 5 and a support 4 are fixed on the bed body. One end of the rocker lever 17 is hinged with the bracket 4 by a pin, and the other end is provided with a roller 9 connected with the feed cam 6. Therefore, the feed cam 6 pushes the roller 9 during the rotation. Wheel 9 and rocker 17 together around O_1 rotation, so that the spindle toggle pin 1 together with the spindle for automatic feed movement. At this time clamping the workpiece movement by the valve cam 7, so live
