Bolt welding system e.g. for automobile body, has mechanical stop for limiting setting movement of robot-controlled bolt welding head transverse to bolt axis

摘要

The welding system has a robot-controlled bolt welding head (3), displacing the T-bolt perpendicular to the workpiece surface, the bolt axis (A) supported at a given spacing from the workpiece contour in the welding position. The drive force of the setting drive for the bolt welding head is limited transverse to the bolt axis in the direction of the workpiece contour, a stop (11) mechanically blocking the setting movement by cooperation with the workpiece contour in the end position. An Independent claim for a method for positioning a robot-controlled bolt welding head is also included.
