Claims

[Scope of utility model registration request]

A welding part of a workpiece in which a concave curved part is provided between a pair of convex curved parts with a straight part interposed therebetween,
In a welding workpiece guidance device for a seam welder that continuously guides the workpiece between the upper and lower welding electrodes of the seam welding machine main body, the base table for positioning and setting the workpiece can be moved linearly and rotatably in the horizontal direction. A first cam pin and a third cam pin are provided on the side of the seam welding machine main body, and a first cam pin and a third cam pin are protruded from the peripheral edge of the base table near a position corresponding to a convex curved part of the workpiece. A second cam pin is provided protruding near a position corresponding to the concave curved portion of the workpiece, and a linear guide rail with which the cam pin can be engaged is provided on the side of the seam welding machine body. , a cam stopper is provided inside the guide rail to temporarily lock each of the cam pins in a rotatable state and release the lock when the cam pins have rotated by a predetermined angle; An entry ratchet is provided which temporarily sinks when the pin abuts and guides each cam pin into the guide rail, while a base table is provided at a suitable position on the inner wall surface of the guide rail so that the first cam pin is centered on the entry ratchet. A first detachment device releases the third cam pin from the guide rail to the seam welding machine main body side when the base table rotates at the cam stopper portion, and a first detachment device releases the third cam pin from the guide rail toward the seam welding machine main body side when the base table rotates at the cam stopper portion about the second cam pin. A second release device is provided to release the cam pin to the seam welding machine main body side, and a biasing device that always biases the base table in one rotational direction, and a concave curved portion of the workpiece is welded. A welding object guiding device for a seam welding machine, characterized in that a rotation drive device is provided for rotating the base table in a direction opposite to the urging device.
