Description

Technical Field

[0001] The utility model belongs to the technical field of radiator processing and fixing, and particularly relates to a welding fixture for an electric vehicle radiator. Background Technique

[0002] The electric vehicle radiator is an important part of the electric vehicle cooling system. Its main function is to dissipate heat to ensure that key components of the electric vehicle, such as power batteries and drive motors, are maintained within an appropriate working temperature range. It is generally made of aluminum alloy materials, and the water pipes and radiator fins are mostly made of aluminum. The working principle of the electric vehicle radiator is mainly based on the heat exchange principle. By allowing the coolant to flow inside the radiator core and the air to pass outside the radiator core, the hot coolant cools down due to heat dissipation to the air, and the cold air warms up because it absorbs the heat dissipated by the coolant. This process achieves the heat dissipation effect through an overall cycle.

[0003] At present, among the components of electric vehicles, the quality of the radiator has a great impact on the performance of electric vehicles, and the welding and forming during the production process will directly affect the quality of the product. Due to the complex structure of the radiator, which is assembled from multiple precision parts, after the parts are assembled in the original production process, a method of placing heavy objects is used to apply pressure for pressing and fixing before welding. However, this method has problems of uneven force application and lack of stable fixation, directly resulting in poor welding quality of the radiator, and further affecting the overall production quality and efficiency.

[0004] Therefore, based on the above problems, we designed a welding fixture for an electric vehicle radiator. Content of the Utility Model

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a welding fixture for an electric vehicle radiator, which solves the technical problems that the existing welding fixture for an electric vehicle radiator has uneven force application and lack of stable fixation, directly resulting in poor welding quality of the radiator, and further affecting the overall production quality and efficiency.

[0006] To achieve the above object, according to an embodiment of the first aspect of the utility model, a welding fixture for an electric vehicle radiator is provided, which includes a profiling stainless steel base, positioning columns arranged on both sides of the profiling stainless steel base, and a welding and forming fixture movably sleeved on the positioning columns;

[0007] Wherein, limiting chutes are arranged on both sides of the welding and forming fixture, a locking block is slidably arranged in each limiting chute, and a locking groove is arranged on the positioning column;

[0008] It further includes:

[0009] The pressure plate is arranged between the welding forming fixture and the profiling stainless steel base. A plurality of pairs of mounting posts that are movably inserted through the welding forming fixture are arranged on the surface of the pressure plate, and a spring is sleeved on each mounting post.

[0010] Further improvement lies in that each pair of the mounting posts are respectively equidistantly and spacedly distributed on the pressure plate.

[0011] Further improvement lies in that column grooves are formed on the welding forming fixture at positions corresponding to each pair of mounting posts, and each pair of the mounting posts are respectively movably inserted into the column grooves.

[0012] Further improvement lies in that one pressing block is arranged on each side of the welding forming fixture, and the two pressing blocks are located inside the two locking blocks.

[0013] Further improvement lies in that a plurality of card slots are formed on the outer side surface of the pressure plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The newly innovatively designed welding fixture realizes a stable and uniform force application mechanism by ingeniously integrating a plurality of springs and mounting posts arranged at equal intervals between the pressure plate and the welding forming fixture. This design significantly enhances the uniformity of the force application during the welding process, greatly reduces the rejection rate, significantly improves the yield rate of the product, thereby ensuring the optimization of the welding quality of the radiator and improving the overall production efficiency and quality.

[0020] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0021] Such as Figure 1 AndFigure 2 As shown in the figure, a welding fixture for a radiator of an electric vehicle includes a profiling stainless steel base 1, positioning columns 11 arranged on both sides of the profiling stainless steel base 1, and a welding forming fixture 3 movably sleeved on the positioning columns 11;

[0022] Among them, limiting chutes 31 are arranged on both sides of the welding forming fixture 3, locking blocks 2 are slidably arranged in each limiting chute 31, locking grooves 101 are arranged on the positioning columns 11, and after pressing the welding forming fixture, the fixture is locked by sliding the locking blocks 2 into the openings of the locking grooves 101;

[0023] As Figure 1 and Figure 2 shown, during implementation, it includes: a pressing plate 5 arranged between the welding forming fixture 3 and the profiling stainless steel base 1, several pairs of mounting columns 4 are movably inserted through the surface of the pressing plate 5 on the welding forming fixture 3, and a spring 41 is sleeved on each mounting column 4;

[0024] Specifically, as a preferred implementation manner, column grooves 42 are opened on the welding forming fixture 3 at positions corresponding to each pair of mounting columns 4, each pair of mounting columns 4 are respectively movably inserted into the column grooves 42, each pair of mounting columns 4 are evenly spaced on the pressing plate 5 respectively, and the column grooves 42 are used for the limiting installation of the mounting columns 4 to maintain the stability of pressing movement, realizing a stable and uniform force application mechanism, and enhancing the uniformity of force application during the welding process;

[0025] In this embodiment, a pressing block 32 is additionally arranged on each side of the welding forming fixture 3, and the two pressing blocks 32 are located inside the two locking blocks 2. During implementation, after the radiator is assembled, it is cooperatively clamped on both sides of the radiator.

[0026] As Figures 1 to 2 shown, in this embodiment, several card slots 51 are opened on the outer side surface of the pressing plate 5 before the application document is implemented for the clamping installation of the assembled radiator. In addition, it should be noted that this application document only improves the welding fixture for the existing radiator of an electric vehicle due to the problems of uneven force application and lack of stable fixation, which directly leads to poor welding quality of the radiator, and further affects the overall production quality and efficiency, and does not involve other aspects; the working principle of the welding fixture for a radiator of an electric vehicle is introduced as follows:

[0027] When this new type is in use:

[0028] The first step: After assembling the parts of the radiator and placing them in the tooling, make the lower surface of the radiator fit with the profiling stainless steel base 1, align the edges with the edges of the tooling, then sleeved the two sides of the welding forming fixture 3 on the positioning columns 11, and align the card slots 51 on the pressing plate 5 with the upper surface of the assembled radiator and cooperate for clamping installation;

[0029] Step 2: Manually press a pair of pressing blocks 32 until the locking groove 101 on the positioning post 11 is exposed on the surface of the welding fixture 3. Then, push the locking block 2 into the notch of the locking groove 101 to lock the upper and lower parts of the entire fixture, that is, lock the welding fixture 3 and the profiling stainless steel base 1. Then, place the entire fixture and the radiator into the brazing furnace for welding. After welding, press down the welding fixture 3 and the pressing plate 5, push the locking block 2 out of the notch of the locking groove 101, and then remove the pressing plate 5 to take out the product.

[0030] The welding fixture with this novel and innovative design integrates multiple springs 41 and mounting posts 4 arranged at equal intervals between the pressing plate 5 and the welding fixture 3, realizing a stable and uniform force application mechanism. This design significantly enhances the uniformity of the force applied during the welding process, greatly reduces the rejection rate, and significantly improves the yield rate of the product, thus ensuring the optimization of the welding quality of the radiator and improving the overall production efficiency and quality.
