Abstract

PURPOSE:To perform stable welding by using plate bodies mounted turnably in the entire direction to support members such as ball joints in constituting press plates. CONSTITUTION:When a pressure is exerted from pressurization devices 5a, 5b to press plates 7a, 7b, plate bodies 7a, 7b act the uniform pressure, via chips 3a, 3b, on materials 1a, 1b to be welded. More specifically, the respective bodies 7a, 7b are made rotatable in the entire direction around the connection point with ball joints 8a, 8b and therefore the pressure of the device 5a is exerted uniformly, via the respective bodies 7a, and chips 8b on the material 1b. The uneven pressurization on the materials 1a, 1b is thus eliminated and the stable welding is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bath welding jig used for welding thin plates and the like.

FIG. 1 is a perspective view showing the structure of a conventional 1# welding tool, and in the figure, 1a+lb is the material to be welded.

Temporary welding materials 1a and lb are placed on the back bar (not shown).
The I+ end is butted Hn, forming a butt line 1c. Then, the materials to be welded 1a and lb are welded while the torch 2 is moved on the combination +1illC.

At this time, the material to be welded 1a is suppressed and fixed by a pressure device 145a such as an air hose through the tip 8a and the holding plate 4a, and the material to be welded 1b is pressed and fixed by a pressure device 145a such as an air hose through the tip 8b and the holding plate 4b. Suppressed by 5b.

Fixed.

By the way, in the above welding jig Q:8, the holding plate 4

, 8b causes uneven pressure to be applied to ef # abduction' la, l b, and as a result, unevenness occurs in the heat M flowing from the welded materials 1a, lb to the chips da, 8b. , the problem arises that stable welding of the welded materials 1a and lb cannot be performed. In addition, as a countermeasure to this problem, a method has been taken in which the number of holding plates 4a+4b is not limited to one, but divided into parts NI, but this causes the same problems as described above and is not a fundamental solution.

This invention is based on the above-mentioned considerations and aims at stable welding.
The welding jig is characterized in that the holding plate is made of a plate-shaped body rotatably attached to a supporting member (for example, a ball joint) in all directions.

Hereinafter, an example of the present invention (/J) will be explained with reference to the drawings. Figure 2 is a perspective view showing the #4 configuration of an embodiment of the unexploded 11J. Corresponding parts are given the same reference numerals.The non-embodiment shown in Fig. 2 is different from the conventional welding jig shown in Fig. 1 in that the holding plate and its supporting member (

A plate connected to a plate? The plate-like body 7a-i is rotatable in all directions like a human upper arm.

Similarly to the holding plate 7a, the holding plate 7b is also connected to the pole joint 8b-j (j=/, 2...n) from the plate-shaped body 7b-j attached to the self-turning plate 111J. It has become. In addition, pole join) 8a -i (
/J Each upper end is fixed to the mounting member 9a 21. Each upper end of the pole joints 3a-j is fixed to a mounting member 9b (not shown).

In such a configuration, when pressure is applied from the pressure devices @5a, 5b to the pressing plates 7a*7b, the plate-shaped 47a

Apply even pressure to the material to be welded (fat lb) through 8b. T, that is, each plate 14=7a-i.

The pressure of the pressurizing device 115b is applied uniformly to the welded material 1a via the tip 8a, and the pressure of the pressure device 115b is applied to the welded material 1b in a gradient or the like via each plate-shaped body 7b-j and the tip 8b. As a result, the JJ pressure unevenness on the welded material 1'+ lb is eliminated, and stable welding can be performed.

In addition, in the above implementation sequence, the plate-shaped body? a-i, 7b

As explained above, the present invention has a structure in which a holding plate is formed by a plate-shaped body attached to a support member such as a ball joint so as to be able to rotate in all directions, and between the chip, the member to be bathed, and the UJ. The first advantage is that stable welding can be achieved by forming a pressure σj at −T.
