【発明の詳細な説明】
本発明は抵抗スポット溶接の電極チップおよび炭酸ガス
アーク溶接チップ等の清掃方法及び装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for cleaning electrode tips for resistance spot welding, carbon dioxide arc welding tips, etc.
スポット溶接ではメッキ鋼板等を溶接するとチップにメ
ッキが付着累積して溶接性を悪くする。When spot welding is used to weld plated steel plates, etc., the plating accumulates on the tip, impairing weldability.
又、炭酸ガスアーク溶接の場合には、スパッタがチップ
やノズルに付着して溶接性を悪くする。Furthermore, in the case of carbon dioxide arc welding, spatter adheres to the tip and nozzle, impairing weldability.
自動溶接やロボットによる溶接ではこれ等の対策が大き
な問題となっていた。These countermeasures have been a major problem in automatic welding and welding by robots.
本発明は、溶接チップの周りに、瞬間的に熱波を発生さ
せ、その熱と衝撃波、気流その他のエネルギによって、
よごれを除失するものである。The present invention instantly generates heat waves around the welding tip, and uses the heat, shock waves, air currents, and other energies to
It removes dirt.
以下、図面にしたがって本発明の特徴を具体的に説明す
る。Hereinafter, the features of the present invention will be specifically explained according to the drawings.
ドーナツ状のチャンバ（５）は溝状又は穴状の吹出口（

浄する。A resistance welding electrode +31 is placed in the center of this chamber (5).
Welding tips +11 and +21 attached to +4) are placed so that their tips are in contact with each other. In this state, the chamber (
5) Fill the inside with a mixed gas of hydrogen, methane, or other highly combustible gas and oxygen, apply a weak current between 11 (21) and release σ1 to generate a spark, then the air outlet (81) The leaked gas ignites the mixed gas in the chamber (5), causing instantaneous combustion and expansion, and a shocking heat wave is blown out from the outlet (8), evaporating dirt and blowing it away for cleaning. do.
チャンバ（５）を、チップ（１１＋２１が被われるよう
にし、燃焼気中にチップ＋１１ ＋２１が置かれるよう
にしてもよい。The chamber (5) may be such that the chips (11+21) are covered and the chips +11 +21 are placed in the combustion gas.
炭酸ガス溶接チップの先端は抵抗溶接チップの場合とよ
ごれの状態が異なるが、同様にして洗浄できる。Although the tip of a carbon dioxide gas welding tip is dirtier than that of a resistance welding tip, it can be cleaned in the same way.
洗浄時に溶融するのを防ぐために、溶接ワイヤα樽の先
端部をチャンバαＧの中央部の穴α９に入れたチップα
Ｂと、チャンバ朋の中央部は接触している。To prevent melting during cleaning, the tip of the welding wire α barrel is inserted into the hole α9 in the center of the chamber αG.
B is in contact with the center of the chamber.

除去する。A ring groove-shaped air outlet aα is arranged around the central portion. This chamber αe is filled with highly flammable gas, a voltage is applied between the carbon rod ■ and the chamber αe, a spark is generated, and the gas in the chamber ue is ignited via the gas leaking from the leak hole α4. In this case, the heat wave that expanded instantaneously hits the air outlet +I! Blows out more impactfully and removes adhering spatter and dirt.

うことができ、溶接作業の合理化が促進される。As described above, according to the present invention, the device for removing dirt near the electrode portion requires only a small chamber, and can be moved freely and placed even in a narrow place. Therefore, automatic welding machines, welding robots, etc. can be easily cleaned in situ, welding with stable quality can be performed continuously, and the rationalization of welding work is promoted.
