記載の抵抗溶接機用電極チツプ。[Claims for Utility Model Registration] 1. A spring chamber in which a coil spring is housed is formed in the electrode chip body, a through hole is bored through the upper surface of the electrode chip body from the spring chamber, and an object to be welded is placed in the spring chamber. A guide pin having a small-diameter head that can be loosely fitted into the inner diameter of the barrel weld nut is installed so as to be movable in the axial direction, and the small-diameter head of the guide pin projects from the through hole to the upper surface of the electrode chip body. The guide pin is supported so as to be freely protrusive and retractable by the biasing force of a coil spring in the spring chamber, and compressed air is supplied into the spring chamber so that the compressed air is blown out from the gap between the guide pin and the through hole when the guide pin is lowered. none,
Furthermore, an insulating bushing is inserted into the through hole of the electrode tip body so that the shaft of the guide pin and the stopper flange at the lower end of the shaft come into contact with the insulating bushing. An electrode tip for a resistance welding machine characterized by being formed by applying an insulating coating to the surface of the base body. 2. Claim 1, wherein the insulating bushing is made of resin, and the insulating coating of the guide pin is made of ceramic coating.
Electrode tip for resistance welding machine as described.
