この考案は、CDスタツド溶接法を用いてナツ

ある。[Detailed description of the invention] This invention relates to a jig used when welding nuts using the CD stud welding method.
ナツトを母材に溶接する場合、従来抵抗溶接が

接される母材が比較的薄い場合には実際に使用で
きない等の不都合があつた。 Resistance welding has traditionally been used to weld nuts to base metals. However, this method not only requires large-scale equipment, but also requires pressure to be applied during welding, making it impractical to use in narrow work sites or when the base material to which the nut is welded is relatively thin. There were some inconveniences.
そこで、この考案の目的は、抵抗溶接法に代つ

単かつ容易に行なうことができるようにすること
にある。 Therefore, the purpose of this invention is to make it possible to simply and easily weld nuts by using the CD stud welding method instead of the resistance welding method.

いることができる。 As is well known, the CD stud welding method involves welding by generating an arc between the stud and the base metal using the discharge current of a capacitor, and since the molten metal scatters due to the arc generation, this method is directly applied to nut welding. In this case, molten metal may adhere to the threaded portion in the through hole of the nut, making it impossible to screw the bolt into the welded nut. Therefore,
According to this invention, a through-hole of a gripped nut to be welded is attached to a conductive holder that has an elastic gripping part that removably grips a nut to be welded at its tip and is fitted to the tip of a welding gun. A rod-shaped body for preventing adhesion of scattered molten metal made of an insulating material and having a thickness approximately equal to the inner diameter of the rod is combined. A plastic material or the like can be used as the material for this rod-shaped body.
以下、この考案を図示前記について説明する。 This invention will be described below with reference to the drawings.

にされる。 Figures 1 to 3 show a jig based on this invention, which consists of a cylindrical holder 1 made of a conductive material.
and a rod-shaped body 2 made of an insulating material, which is fitted into the holder 1, and one end of the holder 1 is provided with an interruption in the longitudinal direction as shown by numerals 3a, 3b, and 3c. An elastic gripping part 5 is formed at the tip thereof to removably grip the nut 4 to be welded, and a spring ring 6 is attached to the outer circumference. The other end of the holder 1 is attached to the tip of a welding gun (not shown) via a connecting member 7 made of a similar material. As shown in FIG. 3, the rod-shaped body 2 is fixed in the holding body 1 by a screw 9 via an annular member 8, and its tip 2a passes through a through hole 4a in the nut 4, and the rod-shaped body 2 The end face of the tip is positioned slightly retracted from the end face 4b of the nut 4 attached to the holder 1. Further, the diameter of the tip 2a of the rod-shaped body 2 is made approximately equal to the inner diameter of the nut 4;
a is made to be able to freely slide within the through hole of the nut 4.

接を行なうことができる。 By using the thus constructed jig of this invention, nuts can be easily and reliably welded using the CD stud welding method without adhering molten metal to the through hole of the nut. Furthermore, even when welding to a thin base material, nut welding can be performed without distorting the base material or burning out the paint on the back surface due to the heat and pressure of welding, unlike conventional resistance welding methods.
