在车削大工件的圆锥时,如果要求精度不很高,可以采用如图1的方法。此种装置很简便,在机床后端装置一块样板靠模,靠模上的斜面按工件要求做出,在横刀架丝杠上装有杠杆,杠杆的另一端装有小滑轮及重锤。工作时光对好靠模与工件的位置,自动走刀时,滑轮沿靠模斜面升起,而由杠杆转动横刀 When turning a large workpiece cone, if the accuracy is not high, you can use the method shown in Figure 1. This kind of device is very simple, a template is set on the back end of the machine tool, and the slant on the mold is made according to the requirements of the workpiece. The lever is mounted on the cross-cutter screw rod, and the other end of the lever is equipped with a small pulley and a heavy hammer. Good working time on the model and the position of the workpiece, automatic take the knife, the pulley along the ramp modeled, and by the lever to rotate the horizontal knife
