内孔螺旋槽零件(图1),一般是在专用拉床上加工,下面介绍一种在普通插床上加工的方法,采用图2所示装置,用仿型法加工。刀具2按工件要求磨成所需刃形。通过L型臂4下端装有的扁平销3无间隙地插入靠模的仿形槽5中。夹具安装在旋转工作台上,工作台应能自由旋转(蜗轮副分离)。为防止加工时轴向震动,工作台锁紧螺母应做微量调整。加工时随插床 The inner part of the spiral groove parts (Figure 1), is generally processed in a special broaching machine, the following describes a method of processing ordinary slot machine, using the device shown in Figure 2, with profiling method. Tool 2 according to the requirements of the workpiece grinding to the desired shape. The flat pin 3 provided on the lower end of the L-shaped arm 4 is inserted into the cam profile 5 without any play. Fixture installed on the rotary table, the table should be free to rotate (worm gear separation). In order to prevent the processing of axial vibration, table lock nut should be adjusted slightly.
