在机械加工生产中,经常在箱体类等零件上遇到各种方向的小孔内要安置孔用弹性挡圈的槽,为适应加工的需要,我们设计了一把钻床用小孔内割槽刀具,经过在摇臂钻床上使用,取得了较好效果。刀具基本上由钻杆、刀杆、棘轮、棘爪和定位体等组成(附图)。工作时先调节刀尖最大外露量使其等于槽深,然后,拔出棘爪转动复位螺钉8,使刀尖缩入钻杆旋转平面内,再通过夹具体插入已钻铰好的
In machining production, often encountered in various parts of the box and other parts of the hole to be placed in the hole with a flexible retaining ring grooves, in order to meet the needs of processing, we designed a drill hole cutting Groove tool, after the use of radial drilling machine, and achieved good results. The cutter basically consists of drill pipe, cutter bar, ratchet, pawl and positioning body (figure). Adjust the maximum exposure of the tool tip to equal the groove depth when working, then pull out the pawl and turn the reset screw 8, so that the tip of the tool retracts into the rotation plane of the drill rod,
