MULTI-SPINDLE CONTROL WELDING EQUIPMENT

PROBLEM TO BE SOLVED: To provide a multi-spindle control welding equipment in which a motor is not degraded by the arc. SOLUTION: In the multi-spindle control welding equipment to draw a welding locus on the welding line, a drive motor to operate each spindle is mounted on a component at a location sufficiently separated for preventing degradation by the radiation heat from a welding arc generation part, and a torch part and a drive spindle in the vicinity thereof are driven from the component via a power transmission mechanism. Since a liner bearing 17 is disposed on a parallel arm 11 with the parallel arm 11 as a guide, the parallel arm 11 slides in the direction of an arrow V by the drive of an AVC spindle motor 8 mounted on the parallel arm 11. A torch supporting rod 10 extending from a tip of the parallel arm 11 is moved by the movement of the parallel arm 11 to operate a torch 2. The torch 2 is rotated by the motor 7 via a chain 14, and a wire 3 can be circulated around the torch 2.
