本考案はシリンダに取付けられるヨーク側の固定電極に
対しシリンダのピストンロッド側の可動電極を対向させ
た所謂Ｃ型溶接ガンにおける給電装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power supply device for a so-called C-type welding gun in which a movable electrode on the piston rod side of the cylinder faces a fixed electrode on the yoke side attached to the cylinder.
一般にこの種ガンにおける可動電極に対する給電は、ピ
ストンロッドとヨークとの間にＵ字状に彎曲されて介装
される可撓性の銅板をもって行っていた。Generally, power is supplied to the movable electrode in this type of gun using a flexible copper plate that is curved in a U-shape and inserted between the piston rod and the yoke.
このためピストンロッドとヨークとの間隔は可撓性の銅
板が十分可撓し得るだけの間隔を保持しなければならず
、それだけガンが大型化する不都合が存した。For this reason, the distance between the piston rod and the yoke must be maintained to allow sufficient flexibility of the flexible copper plate, which inconveniently increases the size of the gun.
本考案はか・る不都合を改良するためなされたものであ
って、ピストンロッドの摺動部を利用して可動電極に給
電するようにした給電装置を提供するにある。The present invention has been devised to improve the above disadvantages, and the object is to provide a power supply device that supplies power to a movable electrode using the sliding portion of the piston rod.

Ｃ型ガンに形成されている。To explain this with respect to the illustrated embodiment, 1 represents a cylinder, and a yoke 2 is attached to the outer casing of the cylinder 1.
A movable electrode 4 faces the fixed electrode 3 provided on the cylinder 1.
It is provided at the tip of a piston rod 5 that slides inside, and is formed into a so-called C-type gun.

ッド５に給電させるようにした。At the rear end of the yoke 2, there is provided a yoke-side cable attachment part 7 for attaching a cable 6 having two terminals 6a and 6b forming a Yin-Yang pair, and a rod-side cable attached opposite to the attachment part 7 is provided. The mounting portion 8 is connected via a conductor 9 to a feeder 10 into which the piston rod 5 is slidably inserted, and the sliding surface of the feeder 10 is provided with inclined blades as shown in FIG. A conductive ring 13 formed by a continuous conductive plate 12 is interposed, and power is supplied to the rod 5 through the ring 13.

It is formed as a feeder to which one terminal of the cable 6 is connected.

できる等の効果を有する。Since the present invention is constructed as described above, power is supplied to the movable electrode 4 via the conductive ring 13 that is in contact with the sliding piston rod 5. A conductive ring 13 formed by a conductive plate 12 having continuous inclined blades is provided on the sliding part of the rod 5, and power is supplied to the movable electrode via the ring 13. Compared to the case where flexible copper plates are provided, the spacing between them can be narrowed enough to obtain a small welding gun, and the inclined vanes 11 of the conductive ring 13 always maintain a constant level with respect to the sliding movement of the piston rod. Since contact can be made with contact pressure, a large current can flow, and even when power is supplied using a cable that is not a pair of Yin and Yang, it has the effect that power can be supplied without causing the cable to slide.
