PURPOSE:To attach and detach easily exchangeably two spot welding guns to and from a welding robot by attaching a bracket to the arm of the welding robot, and providing mount strikers to the two spot welding guns. CONSTITUTION:A bracket 11 is installed to the arm of one welding robot and mount strikers 16 are attached to two spot welding guns 2, 3. The two guns 2, 3 are positioned preliminarily on stands 4, 5, respectively. The bracket 11 at the tip of the arm moves downward an actuator 14 to disengage a lock pin from the striker 16 in the stage of exchanging the gun 3 to the arm of the welding robot attached with the gun 2. The bracket 11 is then horizontally moved and is removed from the striker 16. The removed bracket is turned 180 deg. and is inserted onto the striker 16 of the C-shaped spot welding gun 3, whereby the exchange of the spot welding gun at the tip of the arm of the welding robot is easily accomplished. |
