Claims

[Claims for Utility Model Registration] (1) A mounting base equipped with a grinding tool is provided on the shaping machine body so that it can be raised or lowered, and the mounting base is raised or lowered to grind the electrode tip attached to the tip of the welding machine arm. In an automatic electrode shaping machine that grinds the tip of a chip by bringing a tool into contact with it, a chip holding mechanism that grips the chip at the position where the grinding tool comes into contact with the chip by raising or lowering the mounting base can be detachably attached. An electrode tip holding device for an automatic electrode shaping machine, characterized in that it is disposed in the shaping machine body. (2) The chip holding mechanism is formed of a fixed claw and a movable claw corresponding to the fixed claw, each of which is detachable from the shaping machine body, and the fixed claw can be moved by rotating the welding machine arm. The grinding tool is provided with a chip receiving part that receives an electrode chip carried in at a position facing above or below, and the movable claw is located at a position where the electrode chip received by the chip receiving part is pressed against the chip receiving part and the welding machine. The automatic electrode shaping machine according to claim 1, wherein the automatic electrode shaping machine is mounted so as to be movable between a retracted position and a retracted position that allows the electrode chip to be carried into the opposing position by rotation of the arm. Electrode tip holding device. (3) When the electrode tip is constantly elastically biased in the pushing direction into the recess formed in the attachment part of the welding machine arm and the electrode tip, and the electrode tip is displaced by the upward or downward pressing force of the grinding tool. The automatic electrode according to claim 1 or 2, wherein the tip holding mechanism is provided with a retractable piece that engages with the stepped portion of the recess to prevent its displacement. Electrode tip holding device in a shaping machine.
