Description

[Detailed explanation of the idea] The present invention relates to a hanging device for an X-gun.

Conventionally, in this type of device, the hanging fixture was generally attached to the support leg of the electrode arm, but as the electrode arm becomes longer as in recent years, the center of gravity of the X-gun moves forward and away from the support leg. For this reason, with the hanging fittings attached to the support legs, the X-gun is always suspended in a forward-inclined state, which poses the problem of making the welding work extremely unstable.

It is an object of the present invention to provide a suspension device that solves the current disadvantages and allows the X-gun to be suspended substantially horizontally even in the case of an X-gun with a long electrode arm.

An embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes an electrode chip, 2 an electrode arm, 3 and 3 support legs extending from each electrode arm 2, and 4 each support leg 3.
5 is a pressure cylinder, and the supporting leg 3 of the electrode arm 2 on the upper part thereof is
A bracket 6 is attached which protrudes in the direction of the chip 1 and has a tip that expands to the left and right and is formed on the receiving surfaces 6a, 6a, and an annular rail 7 is attached to the receiving surfaces 6a, 6a of the bracket 6 in parallel with the support shaft 4. A rotating wheel 9 is attached via a plurality of rolling wheels 8 that roll on the outer circumference of the rail 7, and a rotating wheel 9 is suspended from the rotating wheel 9 via seats 10, 10 attached to the outer circumference of the rotating wheel 9 in the diametrical direction. A metal fitting 11 is attached.

In this way, according to the present invention, a bracket 6 is provided that extends forward from the support leg 3 of the X-gun, and an annular rail 7 parallel to the support shaft 4 is attached to the bracket 6. The X-gun is rotatably mounted parallel to the support shaft 4 via a plurality of wheels 8 to a rotating wheel 9 equipped with an annular rail 7. The X-gun can be mounted rotatably and manufactured at low cost, and the X-gun can be freely rotated by the rotating wheel 9 to ensure that the tip always accurately contacts the welding surface even when the welding surface of the workpiece is inclined. At the same time, the rotating wheel 9 is mounted in front of the support leg 3, so even if the electrode arm 2 becomes longer and the center of gravity of the gun moves forward, the gun can always be suspended horizontally for welding. This has the effect of making work significantly easier.
