Grinding machine clamp

The invention belongs to the field of clamps, and particularly discloses a grinding machine clamp. The problem that an existing tool clamp is not high in workpiece clamping precision is solved. According to the grinding machine clamp, pull force is applied to a chuck through a push-pull rod, so that the chuck moves in the direction close to the conical surface of a clamp body, a conical hole in the end of the clamp body makes contact with the conical surface of the outer wall of the chuck, then interaction force can be generated between the conical hole in the end of the clamp body and the conical surface, the chuck is provided with a deformation groove in the chuck hole, under the radial action generated at the conical surface position, the chuck hole shrinks to clamp a workpiece. When aworkpiece is clamped, the bounce of the clamped workpiece in the length direction can be adjusted through radial adjusting screws and end face adjusting screws, wherein the radial adjusting screws andthe end face adjusting sc
