Description

Technical Field

[0001] The utility model relates to the field of grinding machine components, in particular to a grinding knife for inlaying materials and a knife seat thereof. Background Art

[0002] In the vehicle welding workshop, automatic welding guns are required for welding operations. After multiple welding operations with the welding gun, the electrode cap on the electrode rod will be severely oxidized. At this time, an electrode cap grinder is required to repair the electrode cap. The basic principle is similar to that of the forming milling cutter. The forming milling cutter is the most critical part of the electrode cap grinder. The forming tools currently used have certain requirements on the impact resistance and wear resistance of the material. In order to reduce costs, in most cases, materials with weaker impact resistance will be used to ensure cutting performance.

[0003] Because the grinding tool seat is small, the continuously generated chips are likely to clog and scratch the electrode cap. In addition, because the impact resistance of the currently used forming tools is weak, the cutting edge of the blade is easily broken during cutting. Therefore, it is necessary to improve this structure to overcome the above defects. Utility Model Content
