Abstract
The utility model provides an exhaust hook welding structure for an automobile. The exhaust hook welding structure comprises an exhaust hook and a rear crossbeam connecting plate for fixing the exhaust hook, wherein one end of the exhaust hook is provided with a welding end, and the exhaust hook is fixed to the rear crossbeam connecting plate through the welding end. By adopting the abovementioned scheme, the exhaust hook is directly welded on beam parts of the automobile body through carbon-dioxide arc welding, automobile body parts and welding processes are reduced, and production efficiency is improved.
Description
Technical field
The utility model relates to technical field of automobile parts, refers to especially a kind of exhaust suspension hook welded structure for automobile.
Background technology
Along with development and the competition in Global Auto market, travelling comfort is just becoming affects the key factor that user buys, NVH more and more causes the attention of Ge great automobile vendor as the main aspect of travelling comfort, and internal car noise, vibration and car external noise are mainly derived from dynamic assembly, exhaust system.Driving engine is the topmost vibration of car load and driving source, its vibration passes to exhaust system, then pass to vehicle body by suspension hook, cause uncomfortable sensation to passenger, therefore one of the exhaust system most important vibration source that is car load and noise source, therefore reduce vibration and the noise that exhaust system causes and become the important process of controlling NVH in car.
Existing common exhaust suspension hook is first welded on exhaust suspension hook adapter plate by carbon-dioxide arc welding; by spot welding, exhaust suspension hook adapter plate is welded on vehicle body again; it increases welding sequence, needs exhaust suspension hook adapter plate, need to be welded in advance on vehicle body beam piece; increase logistics difficulty; affect body assembly welding operation, affect productive temp, increase labour intensity; and exhaust suspension hook adapter plate by spot-welded on vehicle body, its welding fiduciary level low.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of weld reliable easily for the exhaust suspension hook welded structure of automobile.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of exhaust suspension hook welded structure for automobile, comprise exhaust suspension hook and the after cross member connecting panel for fixing exhaust suspension hook, described exhaust suspension hook one end is provided with welding end, and described exhaust suspension hook is fixed on after cross member connecting panel by welding end.
Wherein, between described welding end and after cross member connecting panel, be provided with carbon-dioxide arc welding layer, described exhaust suspension hook is fixed on after cross member connecting panel by carbon-dioxide arc welding layer.
Wherein, the weld of described welding end and after cross member connecting panel is provided with face of weld, and described face of weld matches with after cross member connecting panel.
Wherein, described welding end is semicylinder structure, and the radius of described welding end is greater than the radius of exhaust suspension hook, and the side plane of described semicylinder is the face of weld matching with after cross member connecting panel.
Wherein, described face of weld is a tangent plane of exhaust suspension hook one end.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, be directly welded on vehicle body beam piece by carbon-dioxide arc welding, reduced bodywork parts and welding sequence, enhance productivity.

Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model for existing exhaust suspension hook adapter plate by spot-welded on vehicle body, welding fiduciary level low problem, provides a kind of exhaust suspension hook welded structure for automobile.
As shown in Figure 1, embodiment of the present utility model provides a kind of exhaust suspension hook welded structure for automobile, comprise exhaust suspension hook 5 and the after cross member connecting panel 4 for fixing exhaust suspension hook 5, described exhaust suspension hook 5 is L-type, described exhaust suspension hook 5 one end are provided with welding end 1, and described exhaust suspension hook 5 is fixed on after cross member connecting panel 4 by welding end 1.
Wherein, between described welding end 1 and after cross member connecting panel 4, be provided with carbon-dioxide arc welding layer 3, described exhaust suspension hook 5 is fixed on after cross member connecting panel 4 by carbon-dioxide arc welding layer 3.
As shown in Figure 2, described welding end 1 is provided with face of weld 2 with the weld of after cross member connecting panel 4, and described face of weld 2 matches with after cross member connecting panel 4.
Wherein, described welding end 1 is the semicolumn bodily form, and the radius of described welding end 1 is greater than the radius of exhaust suspension hook 5, and the side plane of described welding end 1 is the face of weld 2 matching with after cross member connecting panel 4.
Further, the tangent plane that described face of weld 2 is exhaust suspension hook 5 one end.
In the utility model, described exhaust suspension hook 5 is by carbon-dioxide arc welding layer 3 and after cross member connecting panel 4 weld togethers, save exhaust suspension hook adapter plate, exhaust suspension hook 5 is provided with face of weld 2 with after cross member connecting panel 4 cooperation places, both facilitate the location in its welding process, also increased the area of contact of exhaust suspension hook 5 with after cross member connecting panel 4; Solve biography exhaust suspension hook in Vehicle Driving Cycle process, caused the fracture of exhaust suspension hook adapter plate or solder joint to tear because local vibration is excessive, the problem that easily makes traditional exhaust suspension hook come off.
The utility model is directly welded on vehicle body beam piece by carbon-dioxide arc welding, has reduced bodywork parts and welding sequence, has saved weld time, has improved production efficiency, and intensity is high, simple in structure; Alleviate tare; Reduce vehicle body cost; Convenient welding, enhances productivity.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
