我厂加工了一批弯头、三通或四通的工件,由于没有专用设备,用四爪卡盘装夹,每车一头螺纹,都必须找正一次,不仅效率低,质量差,而且劳动强度大。后来,改用如图所示的车弯头夹具,一个弯头(或三通、四通)工件,只装夹一次,就可以把两头(或三头、四头)螺纹车出来。当第一个工件校正后,其余只要略为调整或不必调整即可加工。应用此夹具后,工效显著提高,质量得到了保证。
I plant a number of processing elbow, tee or Stone workpieces, because there is no special equipment, with four jaw chuck clamping, a screw for each car, must find a positive, not only inefficient, poor quality, and labor Strong intensity. Later, use the car elbow fixture shown in the figure, a bend (or three-way, Stone) workpieces, clamp only once, you can put two (or three, four) thread cart out. When the first workpiece is calibrated, the rest can be machined with little or no adjustment. Application of this fixture, the work efficiency significantly improved, the quality has been guaranteed.
