It is necessary to replace the roller electrode 9 when the outer diameter of the housing 1 and the housing 2 becomes larger than the contact shaft diameter of the part b, which is related to the current carrying capacity and strength of the rotating shaft 3, and when the wear amount of the roller electrode 9 is small. There is a lot of waste as there is a lot of material to be disposed of.
本発明は上記の様な従来の欠点を除去することを目的と

１は上記回転軸１５を係止させるナットである。15 is a rotating shaft held in the housings 13, 14 by bearings 16, 16'; 1T is pressed by a spring 18 to the housing 14 at the tapered fitting portion, and is also pressed against the rotating shaft 15 by the pressing force of the tapered portion. Power supply split metal, 19
20 is a roller electrode attached to the rotating shaft 15, and 20 is an oil seal attached to the rotating shaft 15 and the housing 13.
1 is a nut for locking the rotating shaft 15.
以上の様な構成により、いま図示しない溶接変圧器から
ハウジング１３の外部に給電すると、ハウジング１４か
ら給電割メタル１７を通して回転軸１５に到り、ローラ
電極１９に通電される。With the above configuration, when power is supplied to the outside of the housing 13 from a welding transformer (not shown), the power is transmitted from the housing 14 through the power supply split metal 17 to the rotating shaft 15, and the roller electrode 19 is energized.
ここで、給電割メタル１７はハウジング１４とテーパに
より嵌合しており、バネ１８の押圧力のテーパ部の分力
により回転軸１５にも押圧される。Here, the power supply split metal 17 is fitted into the housing 14 through a taper, and is also pressed against the rotating shaft 15 by a component of the tapered portion of the pressing force of the spring 18 .
この様にして、この発明の給電装置によれば、バネ１８

不要となり、又，ハウジング１３．１４の外形寸法を、
回転軸１５の直径を従来のものと同一にしても、小形化
することが可能である。In this way, according to the power supply device of the present invention, the spring 18
By applying a pressing force to the two current-carrying surfaces, the structure is significantly simpler than that of conventional devices, and since it does not have a spring that presses the power-supplying split metal on the radiation against the current-carrying rotating shaft, ．． There is no need to make adjustments to balance the pressing forces of the two springs, and the external dimensions of the housing 13 and 14 can be adjusted to
Even if the diameter of the rotating shaft 15 is the same as that of the conventional one, it is possible to make it smaller.
従って、ローラ電極１９はより多く消耗するまで長期に
亘って使用出来ると共に、円筒形の被溶接材を溶接する
場合に於では、より小型のものの中へ電極給電装置部を
挿入して溶接することが可能である。Therefore, the roller electrode 19 can be used for a long period of time until it wears out more, and when welding cylindrical materials to be welded, it is possible to weld by inserting the electrode power supply unit into a smaller one. is possible.
第５図はこの発明の他の実施例の電極給電装置を示す。FIG. 5 shows an electrode power supply device according to another embodiment of the present invention.

れるよう構成されている。In the figure, 22 and 23 are housings that hold the rotating shaft 24 with bearings 25 and 25', and the power supply split metal 26 is configured to be pressed against the tapered portion of the housing 22 and the rotating shaft 24 by a spring 27. There is.
この様な構造では、図示しない溶接変圧器からハウジン
グ２２の外部に給電すると、ハウジング２３を通ること
なく給電割メタル２６から回転軸２４に通じ，更にロー
ラ電極２８に通じる。In such a structure, when power is supplied to the outside of the housing 22 from a welding transformer (not shown), the power is passed from the power supply split metal 26 to the rotating shaft 24 without passing through the housing 23, and then to the roller electrode 28.
従って、ハウジング２３に電流が流れない為、電気回路
が短くなって、電気抵抗が小くなり、損失する電力も少
く、効果はさらに大きくなる。Therefore, since no current flows through the housing 23, the electrical circuit becomes shorter, the electrical resistance becomes smaller, the power loss is reduced, and the effect is further enhanced.
