Abstract

PURPOSE:To shape the plane part at the top end of an electrode tip without the part remaining after grinding or uneven grinding by rotating a grinding tool around the line which runs the center of the circumferential groove thereof and is perpendicular to the center line thereof and rotating at the same time the tool around the center line of the circumferential groove. CONSTITUTION:As a driving source 16 rotates, a grinding tool holder 7 rotates and a grinding tool 2 rotates integrally with the holder 7 around the line which runs the center of the circumferential groove and is perpendicular to the center line thereof. The longitudinal axis (b) of the tool 2 rotates perpendicularly to the center axis (a) of an electrode tip 18. The tool 2 rotates further around the center line of the circumferential groove and the longitudinal axis (b) of the tool 2 rotates in parallel with the plane part at the top end of the tip 18. The radial surface part and the plane part at the top end of the tip 18 are thus evenly, uniformly and safely shaped and grinding.

Generally, when welding with a Subot/ul III machine, slag adheres to the surface of the electrode tip used in the spot I\J welding machine, and this adhesion forms a resistor at the tip of the electrode tip. Therefore, a predetermined current necessary for welding cannot be obtained, resulting in deterioration of welding performance and reduction in efficiency. Further, a high current is passed through the electrode tip, and the current particularly heats the tip of the electrode tip where the resistor is formed, and the force applied during welding is applied to the tip of the electrode tip. Therefore, the tip of the electrode tip is gradually thermally deformed from its normal shape, resulting in deterioration of welding efficiency and welding performance.

As explained above, the present invention provides a grinding tool consisting of a grinding section having a circumferential groove in which the tip shape of the side surface of the electrode tip and the groove cross section are the same shape. Because it is configured to rotate around a vertical line and at the same time around the center line of its circumferential groove,
Rotation around a line perpendicular to the center line of the circumferential groove of the grinding tool does not sufficiently modify the flat end of the electrode tip;
This drawback is compensated for by the rotation of the grinding tool around the center line of the circumferential groove, so that the part of the grinding part corresponding to the flat surface of the tip of the electrode tip rotates evenly and safely, and the tip of the electrode tip There are no grinding residues or uneven grinding on the flat surface, and not only the R surface of the electrode tip but also the tip flat surface can be shaped and ground evenly and safely at the same time as the R surface, and finishing processing is performed separately. It is not necessary at all, and has the effect of fully demonstrating the original functions of automatic machines and realizing safe automation.
