Abstract
A weight-compensating device (14) for preventing undesired reaction forces during the performance of work on a workpiece is proposed for a tool holder, which is designed in particular to fit on the end (1) of a movement-controlled robot arm (2), and which is adjustable at least in one direction of movement (6) in order to compensate for position and/or design tolerances of the workpiece to be machined (8) in relation to its centre position at the end of the robot arm (1) or similar over a parallel guide (5), which has the form of a guide block (5'), said weight-compensating device (14) acting in the direction (6) of the parallel guide and by means of which the components of the force of weight (F1) of the adjustable part (11) opposite the robot arm end is compensated in relation to gravity in any angle, said force of weight acting in the direction (6) of the parallel guide.
