JIG CHANGING EQUIPMENT IN WELDING EQUIPMENT

摘要

PURPOSE:To change integrally both jigs and to increase the efficiency in the changing work by docking the jig for additional spot welding with the welding jig provided to the first welding equipment each other with its separation freely from the second welding equipment. CONSTITUTION:In case of the jig change a welding jig 4 is moved to the setting position B. The jig 18 for additional spot welding is rocked to the inner part toward a welding jig 4 by the rotation of the main body 23 and both jigs 4, 18 are docked each other by docking mechanism 24 by moving slightly to the upper the jig 18 for additional spot welding with the upper movement of the lift frame 28 on the main body 23 as well. The lift frame 28 is then descended by releasing the fixture of the jig 18 for additional spot welding by the clamp mechanism 29 on the lift frame 28. The jig 18 for additional spot welding is therefore separated from the lift frame 28 and transferred to the welding jig 4, the fixture of the rocking cylinder 8a on the jig base 8 of the welding jig 4 is released and it can be integrally changed with the jig 18 for additional spot welding.
