普通外圆磨削用夹箍操作较繁琐。尤其磨削多台阶外圆时,频繁地上下撤工件,效率低。同时,为防止夹箍与工件在磨削时相对滑动,夹紧螺钉一般拧得较紧,容易造成工件外圆夹伤。 在生产实践中,我对夹箍进行改进(如图1),经过使用效果很好。工作时逆时针扳转锁紧爪2,套入工件使磨头拨盘上的拨杆动锁紧爪2带动 Ordinary cylindrical grinding clamp more complicated operation. In particular, when grinding multi-step cylindrical, the workpiece is frequently withdrawn up and down, which is inefficient. In the meantime, in order to prevent the relative slip between the clamp and the workpiece during grinding, the clamping screw is generally tightened so that the workpiece can easily be injured by the outer circle. In production practice, I improved the clamp (Figure 1), after using the effect is very good. Turn the locking claw counterclockwise 2, set into the workpiece so that the dial on the grinding wheel moving the locking claw 2 driven
