我厂在车制锁接头(如图1)等零件的内螺纹孔时,采用了一种不停车装卸活的夹具,经使用证明:它不但能保证工件内孔与外圆的同心度,并且能显著地节约辅助时间和提高生产效率。现在将这夹具详细介绍如理,供兄弟厂参考。这夹具共分两部分,即夹头部分和操纵部分。夹头部分的结构如图2所示。图中1是调整螺母,旋在调整套9上。2是止动器,共六个,分别装在调整套9的六个槽中。3是爪子,共六个,也分别装在调整套9的槽内,另用弹簧5联结。4是胀簧,共三块,用弹簧6连接成一整体。7是键。8是滑套。10是轴顶套,左端按
I plant in the car lock connector (Figure 1) and other parts of the female thread hole, the use of a non-stop loading and unloading of the fixture, the use of proven: it not only to ensure the workpiece bore and cylindrical concentricity, and Can significantly save time and improve productivity. This fixture will now be described in detail, for Brother reference. This fixture is divided into two parts, namely the chuck part and the manipulation part. Chuck part of the structure shown in Figure 2. Figure 1 is the adjustment nut, screwed on the adjustment sleeve 9. 2 is a stopper, a total of six, respectively, installed in the adjustment sleeve 9 of the six slots. 3 is a paw, a total of six, were also installed in the adjustment sleeve 9 of the groove, the other with a spring 5 link. 4 is a bulging spring, a total of three, with the spring 6 connected into a whole. 7 is the key. 8 is a sliding sleeve. 10 is a shaft sleeve, the left press
