Device for clamping workpiece to machine tool table - has rocker arm coupled by toggle link to actuating slide travelling parallel to table surface

摘要

The clamp(3) has a self-locking toggle link(18) with actuating mechanism(6,7,8). A clamping rocker arm(5) on an intermediate bearing(19) has a jaw (11) at one end and a toggle-joint(18) at the other for a link (15) attached to a slide(17) travelling parallel to the table surface. The mechanism acts on the slide. The rocker bearing can be on a further slide(24) also travelling parallel to the table surface(1) and typically on a positioning arm(9). The toggle joint can be actuated by a pressure-operated ram. ADVANTAGE - Compact, reliable, and allows unhindered insertion and removal of work.
