Device to clamp work piece with uneven surface; has block to take up and disperse tension forces and recess to guide holder of clamp element with stop device to stop rotation of clamp element

摘要

The device has at least one block (3) to take up and disperse tension forces and at least one cylindrical or pyramid-shaped recess to guide a holder of an axially-adjustable tubular or rod-shaped clamp element (2). A clamp element or an element coupled to it has a thread, to transfer sliding motion of the clamp element to rotation of the threaded element against the clamp block. A rotation actuator is coupled to the threaded element. At least one switchable stop device (5) assigned to the clamp element stops the rotation of the threaded element by clamping or friction and has an elastic friction or clamp element.
