Configuration of the Invention (1) Means for Solving the Problems In order to achieve the above object, the present invention forms a truncated conical recess in the center of a disk-shaped holder connected to a power source and driven to rotate. On the inner surface of the truncated conical recess, a pair of end face cutting blades for cutting a flat end face of a welding tip having a truncated conical tip are radially arranged, and the tapered side face of the welding tip is cut. In a tip dresser having a plurality of side cutting edges radially arranged, a separating portion is formed by slightly separating the opposing end portions of the pair of end cutting edges, and the separating portion is positioned at the center of rotation of the holder. And the edge portions of the end face cutting edge and the side face cutting edge are formed in a flat shape having no clearance.

い。(2) Operation According to the present invention having the above-described configuration, the welding tip is inserted into the truncated conical recess provided in the holder, and the end face and the side face of the welding tip are provided on the end face cutting edge and the side face cutting provided on the holder, respectively. When cutting into a truncated conical shape with a blade, the separation part formed by slightly separating the opposing ends of the pair of end face cutting blades is biased to one side from the rotation center of the holder, so that the cutting chips of the welding tip are cut off. Is prevented from accumulating in the vicinity of the rotation center of the end face cutting blade, and as a result, cutting chips of the welding tip are smoothly discharged to the outside. Further, since the side cutting edge and the end cutting edge do not have a clearance, the strength increases, and the blade portion is not damaged even when a large load is applied to the cutting portion.

6 has a first end face cutting edge 5 formed longer than a second end face cutting edge 6 and a separating portion 2 at a position opposed to both end face cutting edges 5, 6.
3 is formed. That is, as best shown in FIG. 3, the separating portion 23 is biased in one direction with respect to the rotation center O of the holder H, and the pair of cutting discharge grooves 9 communicate with each other by the separating portion 23. I do. Then, the both end face cutting blades 5,6
As in the case of the side cutting edge 3, no escape is formed,
5 1, 6 1 rotating direction lagging is flat.
次に、前述の構成を備えた本発明の実施例の作用につ

削される。When the four side cutting blades 3 are inserted into the side cutting blade insertion holes 24 and the holder H fixed with the bolts 4 is mounted on the dresser gear 18 and the hydraulic motor 13 is driven, the driving force is transmitted via the pinion 14 and the idler gear 17. To the dresser gear 18 to rotate the holder H integrally. When the welding tip T provided on the welding robot gun is inserted from the upper and lower tip insertion holes 24,
The side surface T 2 is guided by the truncated conical recess 1 and cut by the four side cutting blades 3, and the end surface T 3 of the holder H
The first and second end face cutting blades 5 and 6 formed integrally with each other are cut.

排出穴10を介して排出される。When the side surface T 2 of the such a manner welding tip T is cut by the side cutting 3, a possibility that the blade portion 3 1 which escape is not formed strength is increased, even subjected to any large load during cutting be broken There is no. The omission of the escape increases the load on the drive source of the holder H, but the use of the high-output hydraulic motor 13 as the drive source ensures sufficient cutting performance. And Thus, cutting chips formed by cutting with the side cutting 3 is discharged via the chip discharge hole 10 formed in the rotation direction leading side of the blade portion 3 1.

Accumulation is prevented. Then, the chips are discharged to the outside from two chip discharge holes 10 communicating with the pair of chip discharge grooves 9. In addition, the end face cutting blades 5 and 6 also have blade portions 5 1 ,
Since the six first rotary direction delayed side not provided with relief, the blade portion 5 1, breakage 6 1 intensity is increased is prevented.

る。C. Effects of the Invention As described above, according to the present invention, the separation portion is provided at the position where the pair of end face cutting blades face each other, and the separation portion is biased to one side from the rotation center of the holder. Is accumulated on the center portion of the holder of the end face cutting blade, and the disadvantage that the cutting ability is reduced is avoided. In addition, the blades of the side cutting edge and the end surface cutting blade have no clearance, so that the strength of the blades can be increased. As a result, it is possible to prevent the blade portion of the side surface cutting edge or the end surface cutting blade from being damaged by the load received during cutting.
