Abstract

A polishing device for a welding tip includes a cylindrical holder; and a polishing unit. The polishing unit includes a blade configured to polish a welding tip. The blade polishes the welding tip dueto rotation of the polishing unit. The holder includes a groove extending along an entire inner circumference of the holder. The groove includes axial groove portions each of which extends along an axis of the holder, and inclined groove portions each of which extends for a specified first distance and is inclined in one direction with respect to the axial groove portions. The axial groove portions and the inclined groove portions are alternately arranged. The polishing unit includes projected portions each of which extends to an inside of the groove, and the number of the projected portionsis two or more and is equal to or less than the number of the axial groove portions.

Description

technical field [0001] The invention relates to a grinding device for a welding tip. Background technique [0002] There is a tip grinding device that grinds a tip by rotating either one of the tip and the cutter in contact with each other. An example of such a grinding device is disclosed in Japanese Patent Laid-Open No. 07-144285. [0003] The inventors of the present application found the following problems with regard to such a tip polishing device. In grinding devices for welding tips, in addition to actuators for translational movement of the welding tips, actuators for rotating the welding tips or cutters are often required. Therefore, there is room for cost cutting. [0004] On the other hand, a method of grinding the tip by rotating the tip or the cutter with the operator's hand is also conceivable. However, this method requires an operator's action and takes man-hours. Therefore, there is room for simplification in such a case as well. Contents of the invent...
