ナツトの位置決め装置。The outer frame is fixed to the machine base, and the inner circumferential surface of the outer frame consists of a guide section formed in the shape of an upper edge near the upper end, and a vertical section continuous to and below the guide section. A predetermined gap is provided between the inner peripheral surface of the vertical part and the outer periphery of the workpiece sheet metal located in the vertical part, and the inner frame is guided by the vertical part of the inner peripheral surface of the outer frame and moves up and down, moving the inner frame upward. The inner frame biasing mechanism is formed to hold the inner frame at a height where its top surface matches the top surface of the outer frame. The lower guide pin, which is formed at the same height as the upper end of the vertical part of the circumferential surface and is attached vertically through the lower electrode so that it can be raised and lowered, is arranged concentrically with the prepared hole in the workpiece sheet metal. is formed in such a way that its upper end faces the lower surface of the workpiece plate placed on the upper end of the outer frame and protrudes by a predetermined distance from the upper end of the lower electrode in the ascending position, and the lower guide pin also has its upper end It has a tapered shape so that it can fit into a pilot hole in a workpiece sheet metal, and a small hole is drilled at the upper end.The upper electrode faces the lower electrode and is movable above it, penetrating the upper electrode up and down. At the same time, the upper guide pin, which can be raised and lowered with respect to the electrode and is arranged concentrically with the lower guide pin, can be slidably inserted into a nut welded to the workpiece sheet metal, and has a conical lower end. A positioning device for a welding nut, characterized in that the upper guide pin is provided with a downward biasing mechanism formed to maintain a posture in which the lower end of the upper guide pin protrudes downward by a predetermined distance from the lower end of the upper electrode.
