Tool control apparatuus containing a welding clamp to realize a particular operation on workpieces, and also an automatic positioning system to control the relative displacement of the welding clamp with respect to these workpieces

摘要

The welding operation of the welding clamp 12 is controlled by a welding control cabinet 15 containing a servo-control unit 16' and an electronic switch 17. The movements of the welding clamp from one welding spot to another are determined by a robot 13 controlled by a control unit 14 provided with a servo-control unit 16. The switch 17 is controlled in such a manner that the welding operation, as well as the start of the opening and closing of the welding clamp 12 are controlled by the welding control cabinet 15 (the robot being immobile), and the movements of the welding clamp, in synchronism with its opening or its closing, are controlled by the control unit 14.
