Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding equipment, and more specifically, to a nested welding tooling for radiators. Background Art
[0002] As one of the most common types of radiators in the market, plate radiators have diverse designs and wide applications, but this also leads to a high degree of customization requirements in the production process. For each different model of radiator, special limit design and tooling customization are required according to its unique size, shape, and performance requirements. This one-to-one customization production method not only increases the processing difficulty and cost but also prolongs the production cycle, making storage and management extremely complex. A large number of special toolings occupy valuable warehouse space and reduce the overall operation efficiency.
[0003] On the other hand, these toolings often adopt complex profiling structure designs to fit the outer contour of the radiator as much as possible. However, in order to ensure that the tooling can smoothly accommodate and fix the radiator and its components, a relatively large tolerance range has to be reserved at the profiling. This compromise in design, although solving the assembly problem, poses a hidden danger in the welding process - it becomes difficult to ensure the effective alignment between components. A slight oversight may cause component displacement during welding, thereby affecting the heat dissipation effect and overall quality of the radiator. Summary of the Utility Model

[0039] Existing welded workpieces mostly use two upper and lower aluminum clamping plates as the bottom plate and the cover plate, and then combine several screws to lock the radiator. This kind of design often has to set a profiling structure on the bottom plate to adapt to the radiator in order to adapt to the welding process. This one-to-one customized production method increases the processing difficulty and cost.
[0040] For this reason, the present utility model proposes a nested welding tooling for a radiator. This welding tooling is not only convenient to operate but also has strong adaptability. When welding radiators of different models and sizes, only by replacing the profiling plate on the welding tooling can this type of radiator be fixed, facilitating subsequent reflow soldering.
[0041] The following will detail the nested welding tooling of the present application through the following embodiments.
[0042] Embodiment 1:
[0043] As Figures 1 - 3 shown, in this embodiment, a nested welding tooling for a radiator includes: a lower base plate 100; an upper cover plate 200, which is arranged up and down with the lower base plate 100, and a chamber for placing the radiator is formed between the lower base plate 100 and the upper cover plate 200; a profiling plate 300, which is detachably arranged on the lower base plate 100 and is adapted to the bottom of the radiator for providing support to the radiator in the chamber; and an adjusting component for adjusting the size of the chamber between the lower base plate 100 and the upper cover plate 200.
[0044] Aiming at the problem that the existing such welding tooling has a narrow application range, for this reason, a profiling plate 300 is added on the basis of the traditional tooling. The profiling plate 300 is a workpiece adapted to the bottom of the radiator, and after the radiator is placed on the profiling plate 300, it can be limited; then the existing fixing method using screws is optimized to enable it to lock and limit radiators of different models and sizes.
[0045] Specifically, the adjusting component includes: a connecting rod 410, one end of which is arranged on the upper cover plate 200 and the other end is provided with a hole; a threaded hole 420, which is opened on the lower base plate 100; and a screw rod 430, which passes through the hole and is threadedly connected to the threaded hole 420 on the lower base plate 100;
[0046] Among them, the connecting rod 410 is rotatably connected to the upper cover plate 200, and there are multiple threaded holes 420 on the lower base plate 100, and all of them are adapted to the screw rod 430.
[0047] After setting the connecting rod 410, the position of the screw rod 430 can be adjusted. By adjusting the cooperation between the connecting rod 410 and the threaded holes 420 at different positions, different-direction forces can be applied specifically, so as to adapt to the clamping of radiators of different sizes.
[0048] It should be noted that there are multiple groups of adjusting components, which are arranged along the circumferential direction of the upper cover plate 200 to realize the clamping of the radiator at different angles.
[0049] Embodiment Two:
[0050] This embodiment is a further improvement made on the basis of Embodiment One.
[0051] In this embodiment, it further includes: a limiting component 500 for adjusting the size of the chamber in the horizontal plane direction, and further limiting the radiator in the horizontal direction.
[0052] Specifically, the limiting component 500 includes: two fixing blocks 510, which are symmetrically arranged on the lower bottom plate 100; two lead screws 520, which respectively pass through the two fixing blocks 510 and are threadedly connected to the fixing blocks 510; and two stoppers 530, which are respectively arranged on the two lead screws 520 and are oppositely arranged.
[0053] By rotating the two lead screws 520, the distance between the two stoppers 530 is changed, and then the fins on the radiator are limited by the two stoppers 530 to prevent displacement during the welding process.
[0054] Embodiment Two:
[0055] This embodiment is a further improvement based on any of the above embodiments.
[0056] As Figure 1 and Figure 3 shown, in this embodiment, a positioning pin 110 is arranged on the lower bottom plate 100, a positioning hole 310 adapted to the positioning pin 110 is formed on the profiling plate 300, and the profiling plate 300 is limited by the positioning pin 110 on the lower bottom plate 100.
[0057] The profiling plate 300 is fixed by means of plugging, which is convenient for installation and disassembly.
[0058] It should be noted that in order to improve the connection stability between the profiling plate 300 and the lower bottom plate 100, multiple positioning pins and positioning holes 310 can be provided.
[0059] In this embodiment, optimally, a plurality of support columns 120 are arranged on the lower bottom plate 100, and the profiling plate 300 is located on the support columns 120.
[0060] By providing the support columns 120, the lower bottom plate 100 and the profiling plate 300 are separated from each other, so that a certain gap is formed between the lower bottom plate 100 and the profiling plate 300. This gap can facilitate gas circulation, enable the radiator to heat up quickly, and at the same time facilitate the volatilization of rosin inside the radiator during welding.
[0061] Optimally, a plurality of first heat dissipation holes 320 are formed on the profiling plate 300, and a plurality of second heat dissipation holes 130 are formed on the lower bottom plate 100 to accelerate gas circulation and facilitate heat dissipation.
[0062] Optimally, the profiling plate 300 is made of a material with a high thermal conductivity coefficient to facilitate heat dissipation.
[0063] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, the practical application, or the improvement of the technology in the market, or to enable other ordinary technical personnel in the technical field to understand the embodiments disclosed herein.
