在小圆柱上钻径向孔,在批量生产中由于夹具不理想就会成为比较麻烦的工序操作。如图1所示的小圆柱工件,通常设计的钻孔夹具是轴端有固定的定位块,移动V形块使工件与钻模板贴合实现夹紧。当工件钻孔完毕后,操作者低头瞄眼用钩子把工件钩出来,工作一个班时间,操作者累得腰酸颈痛,并且加工后的工件轴向尺寸也很难合格。针对上述问题,我们设计和制造了一套小圆柱孔自动退料夹具,如图2所示。其最大特点是凸轮为双 Drilling radial holes in the small cylinder, in the mass production because the fixture is not ideal will become more troublesome process operation. As shown in Figure 1, a small cylindrical workpiece, the borehole fixture is usually designed to have a fixed axial positioning block, move the V-shaped block so that the workpiece and the drill template to achieve clamping. When the workpiece after drilling, the operator bowed eye-hook with a hook to hook the workpiece, work a class time, the operator tired backache neck pain, and the workpiece after the axial dimension is also difficult to pass. In response to the above problems, we designed and manufactured a small cylindrical hole automatic withdrawal fixture, shown in Figure 2. Its most prominent feature is the cam is double
