本夹具可用于有同轴度要求(外圆与中心孔)的轴类工件的车削夹紧。更换工件时可不停车,使用十分方便并可提高效率。装夹时将打好中心孔的轴类毛坯对准活顶尖,同时转动尾架手轮,使顶尖顶紧工件。由于顶尖7向左移动,使锥体4也同时向左移动,则锥度迫使卡爪6将工件卡紧。加工完 The fixture can be used for coaxiality requirements (cylindrical and central hole) of the axis of the workpiece clamping. No need to stop when changing parts, easy to use and more efficient. When clamping the central hole will be punched shaft alignment rough living at the top, while turning the tailstock hand wheel, the top tight top of the workpiece. As the top 7 moves to the left, so that the cone 4 also moves to the left at the same time, the taper forces the claw 6 to clamp the workpiece. Processing finished
