CHUCKING INSTRUMENT OF WELDING DEVICE FOR LARGE STRUCTURE

摘要

PURPOSE: A device for welding is provided to freely weld a large structure, which is difficult to establish a welding location, by using a moving instrument of three-freedom gantry and a six-shaft multi-joint robot. CONSTITUTION: One side of a welding material is located in a connecting aperture(244) formed on a panel(242) of a chucking instrument(240) side by using a fixing tool(244). The chucking instrument of a moving positioner(220) is moved for locating the welding location of a first welding material. Thus, a first welding is operated. Then, the welding material is located for establishing a second welding location. After establishing the second welding location, the second welding is operated. After welding the welding material, the welding material is separated by releasing the fixing tool of the connecting aperture and by being moved by using a transferring crane.
