Among the above-mentioned scheme, make independent piece separately with first support and second support, solve the difficult problem of drawing of patterns, then adopt puncture welding process with first support and second support welding on the grid body, puncture welded advantage is no matter 90 welding or 45 welding, all can easily accomplish, and the while puncture process save material can not produce the heat damage, easy operation, reliable quality, work efficiency height.

Description

Welding point structure of front grating assembly

Technical Field

The utility model relates to the technical field of automobile parts, in particular to a welding point structure of a front grille assembly.

Background

The main function of the automobile radiating grille is to provide air intake and heat dissipation of the automobile front cabin, and meanwhile, the automobile radiating grille plays a role in decoration. Preceding grid assembly is formed by preceding grid body and scaffold weldment, and the welding is carried out after the support will assemble the grid body on, and the structure of conventional welding point is 7X 1 mm's rectangle and the cylindrical muscle of cross, and these two kinds of welding point structures all adopt 90 welding, and this can't realize to 45 welding product structure restriction moulds.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a welding point structure of a front grating assembly, which is firm in welding and simple in process.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a welded structure of preceding grid assembly, includes the grid body, and left and right sides limit position department of grid body extends towards the left and right sides and is provided with the headlight crossbeam, and it has first support to close on tip position department welding on the inboard face of headlight crossbeam, and the inboard face of headlight crossbeam faces nearly upper edge position department and is provided with the second support, first support and second support weld as an organic whole with the grid body through puncture welding process.

Among the above-mentioned scheme, make independent piece separately with first support and second support, solve the difficult problem of drawing of patterns, then adopt puncture welding process with first support and second support welding on the grid body, puncture welded advantage is no matter 90 welding or 45 welding, all can easily accomplish, and the while puncture process save material can not produce the heat damage, easy operation, reliable quality, work efficiency height.

Drawings

FIG. 1 is a schematic view of the overall structure of a front grill assembly;

fig. 2 and 3 are partially enlarged schematic views of the front grill assembly.

Detailed Description

As shown in fig. 1 to 3, a welding structure of a front grille assembly includes a grille body 10, headlamp beams 11 are extended from left and right side edges of the grille body 10 toward left and right sides, a first bracket 20 is welded to a position near an end of an inner side plate surface of the headlamp beam 11, a second bracket 30 is arranged at a position near an upper edge of the inner side plate surface of the headlamp beam 11, and the first bracket 20 and the second bracket 30 are welded to the grille body 10 as a whole through a piercing welding process. Because the bracket assembly formed by the first bracket 20 and the second bracket 30 has a certain bending angle of approximately 45 degrees, if the bracket assembly is made into an integral piece by adopting a common stamping process and is difficult to demold, the first bracket 20 and the second bracket 30 are respectively made into independent pieces, and then the first bracket 20 and the second bracket 30 are welded on the grid body 10 by adopting a piercing welding process, the piercing welding has the advantages that the piercing welding can be easily finished no matter the 90-degree welding or the 45-degree welding is carried out, meanwhile, the piercing process saves materials, no thermal damage is generated, the operation is simple, the quality is reliable, and the working efficiency is high.

Further, the headlight beam 11 is integrally arc-shaped plate-shaped, the first support 20 is integrally L-shaped plate-shaped and comprises a bottom plate 21 welded to the inner side plate surface of the headlight beam 11 and an inclined plate 22 protruding towards the rear side, a welding rib a is arranged on the bottom plate 21, the welding rib a and the grille body 10 are welded into a whole through a piercing welding process, the reliability of connection between the bottom plate 21 and the grille body 10 is improved, and the inclined plate 22 is used for being connected with peripheral parts on a vehicle body.

The whole slat form that is of second support 30, and the inboard face laminating of slat face and headlight crossbeam 11, the outer end of second support 30 extends to first support 20 position department, the inner end extends to on the grid body 10, second support 30 both with grid body 10 welding, weld with first support 20 again, thereby welded joint strength and reliability between grid body 10 and the second support 30 have been improved, be provided with a plurality of rectangle welding points b on the slat, rectangle welding point b is as an organic whole through puncture welding process and grid body 10 welding, adopt puncture welding process equally, reduce the heat damage.

Furthermore, the whole surface of the inclined plate 22 is positioned in the vertical plane and the surface is obliquely arranged towards the inner side, the included angle between the surface of the inclined plate 22 and the surface of the headlamp beam 11 is 45 degrees, and the structure determines that the first support 20 and the second support 30 are made into independent pieces respectively.
