Self-locking clamp
Common cylindrical grinding clamps are cumbersome to operate. In particular, when grinding a multi-step outer circle, the workpiece is frequently lifted up and down, and the efficiency is low. At the same time, in order to prevent the clamp and the workpiece from sliding relative to each other during grinding, the clamping screw is generally tightly tightened, which easily causes the workpiece to be pinched. In the production practice, I improved the clamp (Figure 1) and it worked well. When working, the locking claw 2 is turned counterclockwise, and the workpiece is inserted into the workpiece to drive the locking claw 2 on the grinding head dial.
