我们在车削图1所示工件的对称锥孔时,用图2所示的夹具装夹车削比原工艺提高工效数倍。该夹具工作过程为用拉杆14把夹具体固定在机床的主轴孔内,将正件5装在弯板2的定位孔中,用压板6压紧(这时锥形心轴12缩到定位套内)当车好 19mm和一端锥孔后调头装夹(这时锥形心轴12在弹簧13的推动下使工件自动定位)压紧工件后车另一端锥孔。
When turning the symmetrical taper hole of the workpiece shown in FIG. 1, the workpieces shown in FIG. The work process of the fixture is that the clamp body is fixed in the spindle hole of the machine tool by the tie rod 14 and the positive part 5 is installed in the positioning hole of the bent plate 2 and pressed by the pressing plate 6 (at this moment, the tapered mandrel 12 shrinks to the positioning sleeve ) When the car is good 19mm and one end of the taper hole after the transfer head clamping (then taper mandrel 12 under the push of the spring 13 to automatically position the workpiece) the other end of the workpiece after the workpiece taper hole.
