过去在加工杆形工件上的两孔出,不但效率低,而且还非常吃力,有时还不能保证质量。后来肖棣舟同志利用废物做成一个钻模,很好用,很受工人的欢迎,现把它介绍出来。钻模的构造很简单1是夹具体,开有V形槽;在夹具体1上用螺钉8固定着档铁7。2是钻模板,固定有钻套3。6是垫圈,4是螺钉。工作时,先钻出一个孔,然后调头钻第二孔,这时把定位销 In the past in the processing of rod-shaped workpiece on the two holes out, not only inefficient, but also very difficult, and sometimes can not guarantee the quality. Later, Comrade Xiao Di Zhou made use of wastes as a drill, which was good for use and very popular with the workers. Now it is introduced. The structure of the drilling die is very simple. 1 is a clamp body with a V-shaped groove. A clamp iron plate 7.2 is fixed on the clamp body 1 by a screw 8, a drill plate is fixed, a drill collar 3.6 is a washer, and a screw 4 is a screw. Work, first drilled a hole, and then drilled the second hole, then the positioning pin
