Description
Technical Field
[0001] The utility model belongs to the technical field of cold plate welding, and in particular relates to a cold plate welding tool for new energy vehicles. Background Art
[0002] New energy vehicles are new energy devices, and their core components are power battery modules that provide power. Compared with traditional vehicles, such as fuel vehicles, new energy vehicles not only have no tail gas emissions, but also have higher environmental protection characteristics, and the batteries can be recycled, so they are more economical.
[0003] During the operation of new energy vehicles, the power battery, as the power source, continuously discharges and converts chemical energy into electrical energy during the discharge process. In this process, part of the chemical energy is converted into thermal energy. Therefore, during use, once the thermal energy accumulated in the battery module is high, the temperature of the battery module is high. Therefore, the battery in a high temperature state is not only flammable and explosive, but also seriously threatens the safety of vehicle use.
[0004] Therefore, in order to realize the cooling of the battery module, a cooling plate is often installed on the battery module to cool the battery. The cooling plate is mostly in the shape of a U-shaped structure, which uses the upper cold plate portion (U-shaped structure) to align with the lower cold plate portion before welding. During the welding process, it is necessary to keep the welding parts aligned and not misaligned. Therefore, at present, the upper cold plate portion is often aligned with the lower cold plate portion before welding. However, due to the large length of the cold plate and the special U-shaped structure. Therefore, during the welding process, often after alignment before welding, due to operational errors such as touching the upper cold plate portion or the lower cold plate portion during welding, the aligned upper cold plate portion and the lower cold plate portion are misaligned. Once the misalignment is not discovered in time, the upper cold plate portion and the lower cold plate portion have been partially welded, and it is more cumbersome to correct it again. Specifically, the welding position has been fixed, and re-correction and alignment require the welding position to be disassembled again, but once welded, disassembly is more cumbersome and difficult to operate.

[0037] Example 1
[0038] like Figure 1-5 As shown, a new energy vehicle cold plate welding tool comprises a welding base 1 (a diamond-shaped steel base is adopted), and a U-shaped cold plate positioning mechanism is fixedly assembled and connected to the top of the welding base 1.
[0039] Specifically, the upper U-shaped plate portion and the lower U-shaped cold plate portion constituting the U-shaped cold plate are aligned and positioned by the U-shaped cold plate positioning mechanism, and then sealed and welded along the aligned position.
[0040] The specific structure of the U-shaped cold plate positioning mechanism is as follows:
[0041] The U-shaped cold plate positioning mechanism comprises a lower positioning component 2 assembled and connected to the top position of the welding base 1 and an upper positioning component 3 arranged above the lower positioning component 2 .
[0042] Specifically, the lower positioning assembly 2 includes a first outer U-shaped positioning template 21 and a first inner U-shaped positioning template 22 disposed inside the first outer U-shaped positioning template 21. A U-shaped gap corresponding to the lower U-shaped cold plate portion is formed between the first outer U-shaped positioning template 21 and the first inner U-shaped positioning template 22. Similarly, the upper positioning assembly 3 includes a second outer U-shaped positioning template 31 and a second inner U-shaped positioning template 32 disposed inside the second outer U-shaped positioning template 31.
[0043] Similarly, a U-shaped gap corresponding to the upper cold plate portion is formed between the second outer U-shaped positioning template 31 and the second inner U-shaped positioning template 32 .
[0044] The shapes of the above-mentioned first outer U-shaped positioning template 21, the first inner U-shaped positioning template 22, the second outer U-shaped positioning template 31 and the second inner U-shaped positioning template 32 are as follows: the first outer U-shaped positioning template 21, the second outer U-shaped positioning template 31, the first inner U-shaped positioning template 22, and the second inner U-shaped positioning template 32 all include horizontal plate portions spaced apart on both sides, and an arc portion is integrally formed between the horizontal plate portions.
[0045] The first outer U-shaped positioning template 21 and the first inner U-shaped positioning template 22 are respectively equipped with a plurality of elastic resistance members on their mutually facing side walls; similarly, the second outer U-shaped positioning template 31 and the second inner U-shaped positioning template 32 are respectively equipped with a plurality of elastic resistance members 5 on their mutually facing side walls.
[0046] The upper U-shaped plate portion and the lower U-shaped cold plate portion of the U-shaped cold plate are placed in the corresponding U-shaped gap. At this time, the upper U-shaped plate portion and the lower U-shaped cold plate portion are positioned by the elastic resistance member 5. Specifically, the elastic resistance member 5 not only realizes positioning, but also realizes correction of the discharge posture. The upper positioning component 3 is provided with two layers of elastic resistance members 5 spaced apart from each other, and each layer is provided with a plurality of elastic resistance members 5.
[0047] Specifically, the elastic resistance member 5 includes a resistance rod 51 slidably connected to the side walls of the corresponding first outer U-shaped positioning template 21, the second outer U-shaped positioning template 31, the first inner U-shaped positioning template 22, and the second inner U-shaped positioning template 32, the outer end of the resistance rod 51 is fixedly connected to a spring seat 53, and a return spring 52 is sleeved on the resistance rod 51.
[0048] The outer end of the above-mentioned reset spring 52 is fixedly connected to the spring seat 53, and the inner end of the reset spring 52 is fixedly connected to the side walls corresponding to the first outer U-shaped positioning template 21, the second outer U-shaped positioning template 31, the first inner U-shaped positioning template 22, and the second inner U-shaped positioning template 32.
[0049] The welded upper U-shaped plate portion and the lower U-shaped cold plate portion are discharged (before discharging, the resistance rod 51 is pulled outward in advance to move the resistance rod 51, and the spring is compressed at this time). After discharging, the operator releases the resistance rod 51. Under the elastic restoring force of the spring, the upper U-shaped plate portion and the lower U-shaped cold plate portion are in contact between the resistance rods 51. Under the push of the resistance rods 51, the discharged upper U-shaped plate portion and the lower U-shaped cold plate portion automatically correct their postures (for example, if the distance between the resistance rods 51 and a certain resistance rod 51 is too small, the resistance force is large, and the resistance rod 51 on the opposite side has a larger distance and a smaller resistance force, therefore, the resistance rod 51 is used to correct the posture).
[0050] At the same time, the operator corrects the positions of the upper U-shaped plate and the lower U-shaped cold plate by hand.
[0051] In this way, before welding, the upper U-shaped plate part and the lower U-shaped cold plate part constituting the cold plate are laid out and positioned, and after positioning, the upper U-shaped plate part and the lower U-shaped cold plate part are corrected in posture.
[0052] This ensures that when the upper U-shaped plate portion and the lower U-shaped cold plate portion are combined, the gap is kept neat and not misaligned, and in the positioned state, when welding, the upper U-shaped plate portion and the lower U-shaped cold plate portion are not prone to relative slippage, thereby ensuring that the welding position is neat.
[0053] Example 2
[0054] like Figure 1-5 As shown, based on the structure of Example 1, the lower ends of the side walls of the first outer U-shaped positioning template 21 and the first inner U-shaped positioning template 22 are respectively fixedly connected with a plurality of convex mounting plates A, and the convex mounting plates A are assembled and connected to the welding base 1.
[0055] Specifically, a vertical screw is slidably connected to the convex mounting plate A, and the bottom of the vertical screw is welded to the top of the welding base 1. A support nut supported at the bottom of the convex mounting plate A is threadedly connected to the vertical screw. When the lower positioning assembly 2 and the upper positioning assembly 3 are approaching each other, the lower positioning assembly 2 is approached to the upper positioning assembly 3 by twisting and raising the support nut.
[0056] Example 3
[0057] like Figure 1-5As shown, based on the structure of Example 1, the lower positioning assembly 2 and the upper positioning assembly 3 are assembled and connected via a plurality of height adjustment members 4. Specifically, after the lower positioning assembly 2 positions the lower U-shaped cold plate portion, and the upper positioning assembly 3 positions the upper U-shaped cold plate portion, the positioned upper U-shaped cold plate portion and the lower U-shaped cold plate portion are brought closer to each other until the upper and lower U-shaped cold plate portions collide and align.
[0058] Specifically, the first outer U-shaped positioning template 21 and the second outer U-shaped positioning template 31 are assembled and connected by a plurality of height adjustment members 4; the first inner U-shaped positioning template 22 and the second inner U-shaped positioning template 32 are assembled and connected by a plurality of height adjustment members 4. Similarly, the height adjustment member 4 includes a convex adjustment plate 41 fixedly connected to the side walls of the first outer U-shaped positioning template 21, the second outer U-shaped positioning template 31, the first inner U-shaped positioning template 22, and the second inner U-shaped positioning template 32, respectively.
[0059] A vertical adjustment screw 42 is slidably connected between the convex adjustment plates 41 , and upper and lower ends of the vertical adjustment screw 42 are respectively threadedly connected to a pair of nuts 411 positioned on both sides of the convex adjustment plates 41 .
[0060] During operation, after loosening the nuts that adjust the support at the top and bottom positions of the convex adjustment plate 41, slide the lower positioning assembly 2 and the upper positioning assembly 3 closer to each other until the upper and lower U-shaped cold plate parts are in contact and aligned. After they are close, position the nuts 411 again to support the support at both sides of the convex adjustment plate 41.
[0061] During the adjustment process, the convex adjustment plate 41 slides relative to the vertical adjustment screw 42 .
[0062] Before welding is achieved by the above method, the upper and lower U-shaped cold plate parts in the positioned state are adjusted in height following the correspondingly positioned inner and outer U-shaped positioning templates.
[0063] By using the above-mentioned device components, during the welding process of the cold plate, the upper and lower U-shaped cold plate parts that constitute the cold plate are brought close to each other and abutted against each other in a positioned state, so as to ensure that the upper and lower U-shaped cold plate parts are in close contact with each other and ensure the sealing of the welding; secondly, in the positioned state, it is not easy to be misplaced during the welding process, and the welding seam is effectively guaranteed to be neat.
[0064] Example 4
[0065] like Figure 1-5As shown, based on the structure of Example 1, the left and right sides of the welding base 1 are respectively fixedly connected with end seats (the end seats are fastened by fastening screws); according to the existing conventional method, the end seats are fixedly connected with a rotating shaft B (not shown in the figure), and the rotating shaft B is rotatably connected to the frame (not shown in the figure). According to the existing conventional method, a driving motor (not shown in the figure) is installed on one side of the rotating shaft B. The purpose is to adjust the angle of the entire device during the welding process to facilitate welding, such as facilitating the positioning of the U-shaped cold plate part toward the operator, thereby facilitating the welding operation.
[0066] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
