Abstract

A ball end repairing cutter belongs to the technical field of metal cutting cutters and is used for solving the repairing problem of the electrode ball end of a suspension point welder. The technical scheme is as follows: the ball end repairing cutter comprises a cutter body, a cutter holder and a cutter blade fixed on the cutter body, wherein the cutter blade is provided with an arc cutting edgeand a chip removing chute, the arc cutting edge is arranged at the front end of the cutting blade, and the chip removing chute is connected with the cutting edge; the cutter body is provided with a chip removing channel; and the chip removing chute is communicated with the chip removing channel. The cutter designed by the invention is provided with an arc matched with a processed electrode ball end, easily ensures the surface processing quality when being used for repairing the damaged electrode ball end, is rapid and convenient to repair and has smooth electrode ball end surface just like a new one when being compared with the manual repair, thereby greatly improving the welding quality of a sheet metal component. The invention can be also applied to processing other ball-shaped workpieces.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a milling cutter for repairing a ball-shaped workpiece, and belongs to the technical field of metal cutting tools. Background technique [0002] In the field of automobile manufacturing, the processing process of the automobile body is to use the suspension point welding machine to weld the sheet metal parts together. During the welding process, the upper and lower electrode ball heads of the suspension point welding machine are used to weld the sheet metal parts. After a period of use, the electrode ball head is easy to accumulate impurities or be scratched by sheet metal parts, resulting in damage to the smooth surface of the electrode ball head. Since the surface roughness of the electrode ball head has a direct impact on the welding quality, the electrode ball head needs to be repaired frequently. At present, the repair method of the electrode ball head is to simply repair the surface of th...
