[0002] With the development of the automobile industry, the front windshield of an automobile has gradually abandoned the flat windshield and adopted a curved glass. From the perspective of aerodynamics, the oncoming air flow flowing through the curved glass can reduce eddy currents and turbulence, thereby reducing air resistance. Visually, the overall coordination and beauty can also be felt. In addition to the functions of blocking wind and rain, decelerating, and guiding the flow, the front windshield of an automobile also has the function of safety protection.

[0003] Currently, in the industry, during welding, it is not considered that during the welding process of the main body, due to the heating of the welding machine, the main body is heated, resulting in deformation, and the deformed product is distorted during installation in the main engine factory. Summary of the Utility Model

[0004] The utility model provides a welding device for preventing the deformation of a water tank, which solves the problems raised in the above background art.

[0006] The shape of the imitation table is adapted to that of the lower decorative panel assembly of the front windshield, and a plurality of fixing holes are opened on the imitation table.

[0007] Preferably, an impurity treatment component is further arranged at the rear side of the welding base. The impurity treatment component includes a treatment box, two groups of air extraction pumps installed above the treatment box, an air extraction port installed at the front end of the treatment box, and a plurality of groups of air outlet ports installed on the other side of the treatment box.

[0008] Preferably, the inside of the treatment box is divided into a filtration chamber and a purification chamber by a partition board. The air extraction end of the air extraction pump is communicated with the filtration chamber, and the air outlet end of the air extraction pump is communicated with the purification chamber.

[0009] Preferably, the air extraction port is communicated with the filtration chamber, the air outlet port is communicated with the purification chamber, and a filter plate is arranged at the communication part between the air extraction port and the filtration chamber.

[0010] The beneficial effects of adopting the above technical solutions are:

[0011] 1. During the welding process, this solution can significantly reduce or even eliminate the deformation of the main body caused by heat. Data shows that under the same welding conditions, for workpieces welded using this device, the deformation amount can be reduced by up to more than 80% compared to traditional welding methods. This advantage not only improves the dimensional accuracy and surface quality of the welded parts, but also greatly reduces the workload of subsequent processing and the production cost.

[0012] 2. Through the impurity treatment component, this solution can timely absorb welding slag and gases generated during welding and purify the gases. On the one hand, it reduces the rework and repair costs caused by weld defects and improves production efficiency. On the other hand, it can purify the gases generated during welding, ensure the physical health of workers, and meet environmental protection requirements at the same time.

[0022] The following will further describe in detail the specific embodiments of the present utility model by describing the embodiments with reference to the drawings, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the present utility model and facilitate its implementation.

[0023] Specifically, as Figures 1 to 7As shown in the figure, a welding device for preventing the deformation of a water chute includes a welding base 1, on which a profiling table 2 is installed. Above the profiling table 2, there is an assembly of the lower decorative panel of the front windshield. On the welding base 1, there are also several groups of clamps 3 arranged along the outside of the profiling table 2.

[0024] The profiling table 2 is adapted to the shape of the assembly of the lower decorative panel of the front windshield, and several fixing holes 4 are provided on the profiling table 2.

[0025] It should be noted that when welding the water chute and the lower decorative panel of the front windshield, the lower decorative panel of the front windshield is placed on the profiling table 2 and fixed through the fixing holes 4 adapted to the lower decorative panel of the front windshield. Then, the lower decorative panel of the front windshield is further fixed by the clamps 3, and the components to be welded are sequentially placed for welding work, thereby eliminating the deformation generated by heat during welding of the body.

[0026] In addition, the profiling groove is customized according to the precise three-dimensional model of the body to be welded and is processed by a high-precision numerical control machine tool to ensure the perfect fit between the shape of the groove body and the contour of the body. A special material coating, such as a high-temperature resistant ceramic or silicon carbide coating, is also used inside the profiling groove. These materials not only have excellent high-temperature resistance but also can reduce the direct impact of the thermal stress generated during welding on the body to a certain extent.

[0027] On the rear side of the welding base 1, there is also an impurity treatment component 5, which includes a treatment box 51, two groups of air extraction pumps 52 installed above the treatment box 51, an air extraction port 53 installed at the front end of the treatment box 51, and several groups of air outlet ports 54 installed on the other side of the treatment box 51.

[0028] The inside of the treatment box 51 is divided into a filtration chamber 56 and a purification chamber 57 by a partition 55. The air extraction end of the air extraction pump 52 is communicated with the filtration chamber 56, and the air outlet end of the air extraction pump 52 is communicated with the purification chamber 57.

[0029] The air extraction port 53 is communicated with the filtration chamber 56, the air outlet port 54 is communicated with the purification chamber 57, and a filter plate 58 is provided at the connection between the air extraction port 53 and the filtration chamber 56.

[0030] It should be noted that welding slag will be generated during welding. If not treated in time during the welding process, it will cause defects such as slag inclusions, pores, and cracks in the weld seam, reducing the connection strength.

[0031] In this embodiment, during welding, by starting two sets of air extraction pumps 52, the gases and welding slag generated during welding can be extracted through the air extraction ports 53. The extracted gases and welding slag will enter the filtration chamber 56 and continue to move towards the air extraction pumps 52. During this process, the welding slag is filtered by the filter plate 58 and remains in the filtration chamber 56, while the gas will enter the purification chamber 57 under the action of the air extraction pumps 52. There is a purification liquid placed in the purification chamber 57, and the gas will be directly introduced into the purification liquid to purify the welding gas. Finally, the purified gas is discharged through the air outlet 54.

[0032] The following uses specific embodiments to elaborate on the specific working methods: Embodiment 1

[0033] When welding the water trough and the lower decorative panel of the front windshield, place the lower decorative panel of the front windshield on the profiling table 2 and fix it through the fixing holes 4 adapted to the lower decorative panel of the front windshield. Then, further fix the lower decorative panel of the front windshield with the clamp 3, and then sequentially place the components to be welded to carry out the welding work, thereby eliminating the deformation of the body caused by heat during welding. Embodiment 2

[0034] During welding, by starting two sets of air extraction pumps 52, the gases and welding slag generated during welding can be extracted through the air extraction ports 53. The extracted gases and welding slag will enter the filtration chamber 56 and continue to move towards the air extraction pumps 52. During this process, the welding slag is filtered by the filter plate 58 and remains in the filtration chamber 56, while the gas will enter the purification chamber 57 under the action of the air extraction pumps 52. There is a purification liquid placed in the purification chamber 57, and the gas will be directly introduced into the purification liquid to purify the welding gas. Finally, the purified gas is discharged through the air outlet 54.
