Claims (1)

[Claims for Utility Model Registration] 1. A device for attaching electrodes to clamp horns at symmetrical positions of a butt welding machine,
In a device in which a notch is provided on the inner vertical surface of the clamp horn to incorporate the electrode, the electrode is inserted into the notch, and the clamp horn and the electrode are clamped and fixed via a pressing means. An electrode holder and/or a gib is inserted between the upper surface of the notch, and the inner side is gradually lowered from the outside to the inner vertical surface of the electrode between the electrode and the electrode holder and/or the gib. By forming an inclined pressure surface and applying a pressing force between the electrode and the clamp horn, a force that presses the electrode toward the top surface of the notch and a force that presses the electrode toward the sides of the notch are generated. An electrode mounting device for a butt welding machine, characterized in that and is generated as a component force. 2. The device according to claim 1, wherein the inclination angle of the pressurizing surface is within the range of 91 degrees to 150 degrees with respect to the inner vertical surface of the electrode.
