本考案は、点溶接機の電極チップ先端を補修するチップ
ドレッサー用工具に関する。[Detailed Description of the Invention] The present invention relates to a tip dresser tool for repairing the tip of an electrode tip of a spot welder.
点溶接機の電極チップは軟かい銅合金で造られており、
被加工材を１５０〜２００ｋｇ／ｃＩｔで加圧しなから
１［Ｅｌｉｍ数千乃至数百回と云う点溶接を行う。The electrode tip of the spot welder is made of soft copper alloy.
The workpiece is pressurized at 150 to 200 kg/cIt, and spot welding is performed several thousand to several hundred times.
かかる溶接時には大容量の電流が流れ、電極を冷却して
いるが圧接端面は熱を保ち塑性変形を起して異形となり
、又溶接時に発生するスパッタが凝着したりする。During such welding, a large amount of current flows to cool the electrodes, but the welded end faces retain heat and undergo plastic deformation, resulting in irregular shapes, and spatter generated during welding may adhere.
この為に圧接面積が大となり、又電流が流れにくくなり
所定の溶接強度が得られなくなるので定期的な補修を行
なう必要がある。For this reason, the pressure welding area becomes large, and it becomes difficult for current to flow, making it impossible to obtain the desired welding strength, so periodic repairs are required.
従来かかる補修に使用するチップドレッサー用工具とし

極チップを削り過ぎて電極消耗度が早いという不都合を
有していた。Conventionally, a chip dresser tool used for such repairs has been known as a double-sided serpentine-shaped tool, but the chips from cutting clog the file, making it necessary to remove the chips each time. Also, a tool having a single-blade cutter having the same shape as the electrode has been known, but this tool has the disadvantage that the electrode tip is cut too much and the electrode wears out quickly.

にした。The purpose of the present invention is to provide a tool for a tip dresser that eliminates such inconveniences.As illustrated in the drawing, a tool body 1 is provided with recesses 2, 2 on both the front and back sides corresponding to the shape of the tip of the electrode tip. A plurality of through holes 3 are formed to penetrate between the recessed holes 2, 2, and the tip of the electrode tip is cut by the hole edge 4 of each of the through holes 3 opening in each of the recessed holes 2. did.

。Further, the recessed hole 2 is provided with a guide tapered surface 2a at its entrance end to guide the introduction of the electrode chip, and the bottom portion 2 of the recessed hole 2
b has the same shape as the tip of the electrode tip and is hardened, and a plurality of through holes 3 of different sizes are arranged in a staggered pattern so that the entire tip of the electrode tip can be cut into a predetermined shape.
次に本考案の使用状態を説明する。Next, the state of use of the present invention will be explained.
