我厂过去加工如附图中的工件,是在三爪卡盘上进行的。由于装卸工件时要开车及关车,所以浪费很多时间。同时,这工件加工时的切削力很大,工人要费很大劲才能把它夹得牢靠。针对这种情况,我们改进了一种不停车装卸工件的夹具,在保证质量的基础上,提高了劳动生产率20%左右,并降低了工人的劳动强度。下面就是这夹具的结构和操作方法。夹具结构夹具的结构如附图。图中1是套筒,旋紧在车床主轴上,筒壁 I plant in the past processing as shown in the drawings of the workpiece, is carried out in the three jaw chuck. As the loading and unloading of parts to drive and off the car, so wasting a lot of time. At the same time, the cutting force of the workpiece processing is very large, the worker takes great effort to be able to clip it firmly. In response to this situation, we improved a fixture that does not stop loading and unloading workpieces, which improves the labor productivity by about 20% on the basis of quality assurance and reduces the labor intensity of the workers. Here is the structure and operation of this fixture. Fixture structure Fixture structure as shown in the drawings. Figure 1 is a sleeve, tighten the lathe spindle, the cylinder wall
