Description

Technical Field

[0001] The utility model belongs to the field of radiator manufacturing, and in particular relates to a welding tool for a radiator. Background Art

[0002] A radiator is a heat exchange device used to control the temperature of a device. It increases the heat dissipation efficiency by increasing the heat dissipation area or using efficient heat dissipation materials. Radiators are widely used in electronic equipment, automobiles, aerospace and other fields, especially in high-temperature components such as CPUs, GPUs, engines, etc. that require a lot of heat dissipation. The design and manufacture of radiators are crucial to ensure the stable operation and long-term reliability of the entire system.

[0003] The manufacturing process of the radiator includes multiple steps such as material selection, molding, cutting, and welding. The welding process is to assemble multiple radiators together by welding to meet higher heat dissipation requirements.

[0004] Traditional radiator welding mostly uses melting welding technology, such as argon arc welding or electron beam welding. However, with the development of technology, friction welding has gradually been applied to the welding process of radiators due to its advantages such as high welding quality, small heat-affected zone, and small deformation. Friction welding uses the heat generated by the friction between the contact surfaces of the workpieces as a heat source to achieve welding, and is particularly suitable for parts such as radiators that have high requirements for welding quality.

[0005] Although friction welding technology has shown significant advantages in radiator welding, the existing radiator welding tooling still has some shortcomings. The fixing method is single. The existing welding tooling often adopts a fixed clamp design, lacks adjustability, and cannot adapt to radiators of different specifications and shapes, which limits the versatility and flexibility of the tooling. There is a lack of upper limit mechanism. When performing friction welding, the welding part needs to withstand a certain pressure to ensure the welding quality. The existing tooling lacks an effective upper limit mechanism, which makes the radiator easy to move during the welding process, affecting the uniformity and stability of the welding. Utility Model Content

[0006] The utility model aims to provide a welding tool for a radiator, so as to solve the technical problems of deviation in the friction welding process of the radiator and that the tool can be adjusted to cope with radiators of different specifications.

[0007] In order to achieve the above-mentioned purpose, the specific technical scheme of a welding tool for a radiator of the utility model is as follows:

[0010] The first movable baffle cooperates with the first fixed baffle, and the second movable baffle cooperates with the second fixed baffle to clamp and fix the heat sink to be processed from two directions respectively, and the lower pressing plate presses the heat sink to be processed onto the base from above.

[0011] As a further improvement of the present invention, the limiting structure also includes limiting columns arranged on the corresponding sides of the base, and a support plate connected to the limiting columns; the lower pressure plate is connected to the bottom of the support plate through a lower pressure adjusting member, and the lower pressure distance of the lower pressure plate is adjusted by the lower pressure adjusting member.

[0012] As a further improvement of the present invention, one end of the support plate is rotatably connected to the limiting column, and the other end is placed on the limiting column, and the support plate is placed horizontally.

[0013] As a further improvement of the present invention, the first adjustment structure also includes a plurality of first adjustment columns arranged on the corresponding side of the first fixed baffle, the first movable baffle is connected to the first adjustment column through a first adjustment member, and the extension and retraction degree of the first movable baffle is adjusted by the first adjustment member.

[0014] As a further improvement of the present invention, the second adjustment structure also includes a plurality of second adjustment columns arranged on the corresponding side of the second fixed baffle, the second movable baffle is connected to the second adjustment column through a second adjustment member, and the extension and retraction degree of the second movable baffle is adjusted through the second adjustment member.

[0015] As a further improvement of the present invention, the second movable baffle is composed of a plurality of second movable blocks, which are connected to the corresponding second adjusting columns through the second adjusting member.

[0016] As a further improvement of the present invention, the first fixed baffle plate and the second fixed baffle plate are vertically arranged on the base and vertically connected.

[0017] As a further improvement of the present invention, the first fixed baffle plate or the second fixed baffle plate is arranged along the welding position of the heat sink to be processed.

[0018] Beneficial effects:

[0019] By providing an adjustable first adjustment structure and a second adjustment structure, radiators of different specifications and shapes can be adapted, thereby improving the versatility and flexibility of the tooling and reducing the cost and time of designing special tooling for different radiators.

[0020] The introduced upper limiting structure effectively prevents the displacement and deformation of the radiator during welding, ensures the uniformity and stability of welding, and thus significantly improves the quality of the welding joint.

DETAILED DESCRIPTION

[0027] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0028] Implementation example:

[0029] like Figure 1-2As shown, a welding tool for a radiator includes a base 10, a first fixed baffle 20, a second fixed baffle 30, a first adjustment structure 40, a second adjustment structure 50, and a limiting structure 60. The first fixed baffle 20 and the second fixed baffle 30 are erected on the base 10 at an angle of 90 degrees, and the first adjustment structure 40 and the second adjustment structure 50 are respectively erected on the corresponding sides of the first fixed baffle 20 and the second fixed baffle 30 to clamp and fix the radiator 70 placed in the middle, and the limiting structure 60 clamps the radiator 70 on the base from above.

[0030] The first adjustment column 42 in the first adjustment structure 40 is erected on the side of the base 10 opposite to the first fixed baffle 20, and the two are respectively erected on the corresponding sides of the radiator 70. In this embodiment, the first adjustment member 43 is an adjustment bolt, which passes through the first adjustment column 42 and is connected to the first movable baffle 41. The first movable baffle 41 is adjusted to extend toward the radiator 70 by rotating the adjustment bolt. The first movable baffle 41 abuts against the surface of the radiator 70 and clamps the radiator with the first fixed baffle 20.

[0031] The second adjustment structure 50 is similar to the first adjustment structure 40. The second movable baffle 51 is composed of a plurality of second movable blocks 54. Each second adjustment column 52 extends the second movable block 54 toward the radiator 70 through an adjusting bolt. The second movable block 54 to be used is selected according to the size of the radiator 70. The second movable block 54 is adjusted to extend toward the radiator 70 by rotating the adjusting bolt. The second movable block 54 abuts against the surface of the radiator 70 and clamps the radiator with the second fixed baffle 30.

[0032] The limiting columns 62 in the limiting structure 60 are respectively erected on the base 10 on both sides of the radiator 70 to avoid intersection with the welding part 71 of the radiator 70. The two ends of the support plate 63 are respectively connected to the upper ends of the limiting columns 62, one end is rotatably connected to the limiting column 62, and the other end is detachably placed on the upper end of the limiting column 62 on the other side, and the support plate 63 is placed horizontally. The lower pressure plate 61 is connected to the lower side of the support plate 63 through the lower pressure adjustment member 64. In this embodiment, the lower pressure adjustment member 64 is an adjustment bolt. By rotating the adjustment bolt, the lower pressure plate 61 is adjusted to move toward or away from the radiator 70 below. The lower pressure plate 61 abuts against the upper end surface of the radiator 70 and clamps the radiator with the base 10.

[0033] like Figure 3As shown, in this embodiment, two L-shaped radiators 70 need to be connected by friction welding. First, the two radiators 70 are assembled together through the corresponding connection parts, and then a fixed connection is formed by the friction welding process of the welding part 71. The existing welding tool lacks a limiting structure on the top, which makes the two radiators easy to offset during the welding process, affecting the uniformity and stability of the welding. At the same time, the longer radiator will be slightly deformed during the production process, which can also be corrected during the welding process through the limiting structure 60.

[0034] When in use, firstly, two heat sinks 70 are spliced ​​and placed along the angle between the first fixed baffle 20 and the second fixed baffle 30, and then the first adjustment structure 40 and the second adjustment structure 50 are adjusted to clamp the heat sink 70 in the horizontal direction, and finally, the support plate 63 is rotated and the lower pressure plate 61 is adjusted to clamp the heat sink 70 on the base 10. After welding is completed, the limiting structure 60 is opened, and the first adjustment structure 40 and the second adjustment structure 50 are used to take out the welded heat sink 70.

[0035] Setting the welding part 71 of the radiator along the first fixed baffle 20 or the second fixed baffle 30 can avoid interference and deviation during the welding process as much as possible. When placing the radiator 70, the long side of the radiator 70 is placed along the second fixed baffle 30. By selecting the second adjustment block 54, radiators 70 of different sizes can be adapted.

[0036] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
