三通管通常是装在四爪卡盘上,经过校正后分几次加工出来的,生产效率很低。在增产节约运动中,我们改进了一个自动定位夹具。过去10分钟加工1件,现在只要5分钟,提高生产效率1倍。夹具如附图所示。工作时,把工件放在V形铁中,用螺钉夹紧,即可进行加工。加工一个管后,略松螺钉,使弹簧把V形铁抬起,然 Tee pipe is usually mounted on a four-jaw chuck, after correction, divided into several processing, the production efficiency is very low. In the campaign to increase production and saving, we have improved an automatic positioning fixture. In the past 10 minutes processing 1, now just 5 minutes, improve production efficiency 1 times. Fixture as shown in the figure. Work, the workpiece on the V-shaped iron, with a screw clamp, you can carry out processing. After machining a tube, slightly loosen the screw so that the spring lifts the V-shaped iron, however
