Claims

[Scope of utility model registration request]

(1) In a workpiece grounding device for electric welding when electrically welding a workpiece to be welded around a workpiece having a rod-shaped part, the end face of the rod-shaped part of the workpiece is made almost perpendicular to the axis center line of the rod-shaped part, and one end A rotor member made of an annular electric conductor, an annular sliding plate and a number, and a rotary member are attached to the round bar part of the rotor-lead fixing member, which is made of a magnetic material and electrically grooved round bar with a flange. Fit loosely so that it touches the flange,
Attach a nearly disk-shaped tightening member to the end of the round bar by compressing a spring between it and the sliding plate, press one rotary member against the flange, connect a ground wire to the rotary and one member,
Rotary Earth 9 A workpiece grounding device for electric welding, characterized in that the flange portion of the fixing member is attached to the end surface of the rod-shaped portion of the workpiece using a conductive permanent magnet.

(2) The tightening member is attached to the end of the round bar part with a screw so that its position in the axial direction can be adjusted, so that the elastic force of the spring can be adjusted. Workpiece grounding device for electric welding.
