Description

Tilting jig for cowl cross welding {Cowl cross welding jig}

The present invention relates to a tilting jig for cowl cross welding, and more particularly, to effectively and stably support and clamp the cowl cross, thereby quickly and easily removing difficult parts while welding the robot robot. The present invention relates to a tilting jig for cowl cross welding, which can solve the thermal deformation problem caused by welding, and can reduce the process and welding time by improving the weldable range.

Cowl Cross is one of the core parts of an automobile, and is formed by welding 40 to 50 press parts or brackets at each position on the Cowl Cross Bar.

Since so many parts are welded to the cowl cross bar by position to form a single cowl cross, high heat during welding can lead to deformation of the cowl cross bar.

Therefore, the welding order to catch heat deformation is very important, but the existing jig is limited to the range that the robot can move to the welding area, so the process can be added according to the order and location, and the welding efficiency is reduced and the welding time is increased. There is a problem.

As a result, in view of the fact that such a problem cannot be effectively and stably supported by the cowl cross clamping, it is necessary to research and develop a new concept of the cowl cross welding tilting jig previously unknown.

In the meantime, it is possible to solve the heat deformation problem due to the welding by making it possible to weld the difficult part of the welding quickly and effectively, and to reduce the process and welding time by improving the weldable range.

The tilting jig 100 for cowl cross welding is a jig in which a cowl cross bar (C / B, Cowl Cross Bar, see FIGS. 3 and 9) to which a plurality of parts are to be welded is tiltable.

As described above, 40 to 50 press parts or brackets can be welded to the Cowl Cross Bar (C / B) by position, resulting in a car core part called a Cowl Cross. A tilting jig 100 for cowl cross welding is a means for tiltably supporting a cowl cross bar (C / B) to weld many parts by position.

Since a large number of parts are welded to the cowl cross bar (C / B, Cowl Cross Bar) by position to form a single cowl cross, the high heat during welding may cause deformation of the cowl cross bar (C / B). have.

Therefore, the welding order to catch heat deformation is very important, but the existing jig is limited to the range that the robot can move to the welding area, so the process can be added according to the order and location, and the welding efficiency is reduced and the welding time is increased. I had to do it. However, since the tilting jig 100 for cowl cross welding applied to the present embodiment has an efficient structure different from that of the prior art, the welding work can be performed smoothly and quickly by interaction with the welding robot 200.

The tilting jig 100 for cowl cross welding includes a base unit 110. The base unit 110 forms a lower support structure of the tilting jig 100 for cowl cross welding.
