为了减少工件的装夹时间,提高劳动生产率,现介绍一种既方便又简单的不停车夹具(可加工φ8～φ3Omm的轴类件)。 1.先在三爪上夹一段直径比工件大10mm的圆钢。 2.在圆钢上打一个孔,孔的直径比工件小2mm。 3.在孔的右端倒出4°锥面,并经淬火。 4.车削加工开始时,先开车,用左手把工件一端塞进4°的锥度夹具内,右手摇动尾架手柄,使顶尖顶住工件的中心孔,待工件旋动后即可进行加工。 In order to reduce the clamping time of the workpiece and improve the labor productivity, we introduce a convenient and simple non-stop fixture (can handle φ8 ~ φ3Omm shaft parts). 1. First in the three-jaw clamp a diameter of 10mm larger than the workpiece round bar. 2. Make a hole in the round bar, the hole diameter smaller than the workpiece 2mm. 3. Pour a 4 ° cone at the right end of the hole and quench. 4. Turning start, first drive, with the left hand into the workpiece taper 4 ° into the fixture, the right hand shake the tailstock handle, the top to withstand the center hole of the workpiece, to be processed after the workpiece is rotated.
