Abstract:
A gripper with two gripper jaws actuatable pneumatically or hydraulically by a piston guided and sealed in a cylinder, where the piston, in order to drive the gripper jaws, is hinged to the gripper jaws via a lever transmission, characterized in that the gripper jaws are each provided with a respective single-armed lever at their ends, and the piston is hinged via a piston rod to a coupling point, each coupling point being located between each gripper jaw and the pivot of each single-armed lever, in that the piston rod is provided at its end area remote from the piston, with a guide slot which extends perpendicular to its longitudinal axis and is for the displaceably guided reception of coupling pins which form the coupling point of the two single-armed levers, and in that the two single-armed levers, viewed in the direction of the longitudinal axis of the piston rod, are arranged laterally offset next to the latter so as to be swivellable and the pivots of the two single-armed levers have a common pivot axis.
