ABSTRACT:
A device for balancing of positional and spatial tolerances, for example, for a gripper of an industrial robot at the end of the work arm of the indistrial robot, is furnished, where plates are held at a distance (h) for an intermediately disposed movable plate (4a). The movable plate (4a), provided with an attachment for a flange (6) of a gripper, or the like, protrudes with lateral play of motion through an opening of a fixed plate (2b), disposed toward the gripper, whereby the movable plate (4a) is guided via conical centerings in a fixed-point position. In order to be able to balance even larger positional deviations in a horizontal plane with a very small expenditure of force, it is disclosed that a pressure-medium bellows cylinder (7), connected to a pressure-medium system, is disposed between the movable plate (4a) and a centering element support (8), disposed remote from the gripper.
