Description

Technical Field

[0001] This utility model belongs to the field of temperature equalization plate processing technology, specifically relating to a welding equipment for temperature equalization plate processing with pre-pressing function. Background Technology

[0002] In the processing of heat exchange plates, welding is one of the key steps. Currently, there are specialized welding equipment for heat exchange plates in use. Under the existing technology, when welding heat exchange plates, workers need to first fix them on the placement platform of the welding equipment using a fixing device before starting the equipment to perform welding.

[0003] The applicant found that the existing fixing device has obvious operational limitations: it relies on workers to repeatedly turn the screw to pre-press the rubber head at the bottom of the screw onto the surface of the heat spreader plate to achieve fixation. Although this fixing method is simple to operate, it has significant drawbacks. The loading and unloading of the heat spreader plate requires repeated screw operation. When facing batch welding tasks of multiple heat spreader plates, this operation mode will greatly increase the auxiliary time for loading and unloading, affecting the improvement of processing efficiency.

[0004] To address the aforementioned issues, this application proposes a welding device for processing a heat exchange plate with a pre-compression function. Utility Model Content

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0037] Please see Figures 1-7 The present invention provides the following technical solution: a welding equipment for processing a heat exchange plate with a pre-pressing function, including a welding machine body 1 and a base 2 connected to the bottom of the welding machine body 1. The base 2 is provided with symmetrically distributed linear grooves 3, and a linear slider 4 is slidably embedded in the linear grooves 3.

[0038] The welding machine body 1 has an installation slot 5 in the middle, and a feeding screw 6 is rotatably installed in the installation slot 5. A screw seat 8 is threadedly connected to the feeding screw 6. A screw motor 7 that drives the feeding screw 6 is provided on one side of the base 2.

[0039] The top surfaces of the two linear sliders 4 and the screw base 8 are flush with each other and a placement platform 9 is fixed thereon;

[0040] The heat spreader is placed on the placement platform 9. When the screw motor 7 is started in forward rotation mode, it can be driven by the feeding screw 6 to move towards the welding head on the welding machine body 1 to achieve welding. After welding is completed, the feeding screw 6 is started in reverse to remove the processed heat spreader for easy unloading.

[0041] It also includes a pre-compression mechanism 10. Two pre-compression mechanisms 10 are symmetrically arranged on the placement platform 9 to limit and fix the temperature equalization plate placed on the top surface of the placement platform 9.

[0042] Preferably, by Figure 2As shown, in this embodiment, a rubber pad 11 is laid on the top of the placement platform 9. The rubber pad 11 has the function of anti-slip and anti-wear, which can reduce the wear on the bottom surface of the heat exchange plate and improve the pass rate.

[0043] Preferably, by Figures 1 to 3 As shown, in this embodiment, the pre-compression mechanism 10 includes a moving unit and a positioning unit;

[0044] The moving unit includes:

[0045] The support plates 12 are symmetrically arranged on both sides of the placement platform 9, the linear guide rail 13 is arranged on the top surface of the placement platform 9, the linear slide 14 is slidably installed on the linear guide rail 13, and the toggle clamp 15 is fixed to the top of the linear slide 14. This arrangement makes it easy for the two toggle clamps 15 to adjust the distance according to the temperature equalization plate of different widths.

[0046] The toggle clamp 15 utilizes the lever principle, allowing the preload rod to be quickly pressed down and lifted by turning the handle, replacing the traditional screw-type fixing and reducing operation time.

[0047] Preferably, by Figures 3 to 5 As shown, in this embodiment, the positioning unit includes:

[0048] A positioning plate 16 is fixed on a vertically placed platform 9, and a plurality of equally spaced triangular locking holes 17 are provided on the positioning plate 16.

[0049] A support frame 18 is fixed on the linear slide block 14. A support column 19 is provided on the side of the linear slide block 14 facing the support frame 18. A movable rod 20 is installed on the support column 19. A sliding cavity 22 that is slidably connected to the support column 19 is opened in the center of the movable rod 20.

[0050] The support frame 18 has a through hole at its center that is slidably connected to the moving rod 20;

[0051] The end of the moving rod 20 away from the linear slide 14 is provided with a triangular block 21 that matches the triangular hole 17. Both the triangular hole 17 and the triangular block 21 have inclined surfaces facing the placement platform 9, and their other surfaces are vertical surfaces, which makes it easy for the linear slide 14 to move toward the placement platform 9 and will not retract.

[0052] The outer ring of the supporting column 19 is fitted with a return spring 23. The two ends of the return spring 23 are connected to the linear slide 14 and the moving rod 20 respectively. The moving rod 20 can move by the elastic force of the return spring 23, so that the triangular block 21 is engaged in the triangular hole 17. During operation, the linear slide 14 is pushed directly towards the placement platform 9. Due to the inclined plane, the triangular block 21 will be squeezed and forced to disengage from the triangular hole 17 (the return spring 23 is compressed). When the appropriate position is reached, it can be stopped. The triangular block 21 is reset by the elastic force of the return spring 23 and inserted into the corresponding triangular hole 17, which makes it easy to adjust and use according to the different widths of the heat exchange plate, and the operation is convenient.

[0053] Preferably, by Figures 3 to 5 As shown, in this embodiment, the moving rod 20 is provided with a smooth surface 24, and the through hole of the support frame 18 is provided with a smooth wall 26 that matches the smooth surface 24. This setting has a limiting function, which can prevent the moving rod 20 from rotating accidentally during operation, thereby ensuring that the triangular block 21 and the triangular hole 17 always remain in correspondence.

[0054] Preferably, by Figures 2 to 7 As shown in this embodiment, an auxiliary plate 25 is provided on the linear slide 14 and on the side close to the support frame 18. An operating plate 27 is provided on the moving rod 20 and is distributed parallel to the auxiliary plate 25. During operation, the operator's thumb rests on the operating plate 27 and the other four fingers grip the auxiliary plate 25. By squeezing with a little force, the moving rod 20 can be moved toward the linear slide 14, thereby causing the triangular locking block 21 to disengage from the triangular locking hole 17 (the return spring 23 is compressed). During this process, the linear slide 14 can be moved away from the placement platform 9 (the toggle clamp 15 is moved away from the placement platform 9), which makes it easier for the two toggle clamps 15 to be adjusted and used according to the different widths of the heat exchange plates.

[0055] Preferably, by Figure 2 , Figure 6 and Figure 7 As shown, in this embodiment, a rubber pressure head 28 is provided on the preload rod of the toggle clamp 15, and an installation rod 29 is provided on the preload rod of the linear slide 14. A retaining ring 30 is sleeved and fixed on the outer surface of the installation rod 29. A pre-made hole 31 adapted to the installation rod 29 and an annular groove 32 adapted to the retaining ring 30 are provided on the top surface of the rubber pressure head 28. If the rubber pressure head 28 is damaged after long-term use, it can be directly pulled out and a new one installed for easy use.

[0056] The rubber pressure head 28 of the toggle clamp 15 can be quickly replaced through the snap-fit ​​structure of the snap ring 30 and the annular groove 32, ensuring that the heat exchange plate can be tightly fixed during pre-pressing and preventing surface scratches.

[0057] Components not described in detail in this article are existing technologies.

[0058] The working principle and usage process of this utility model are as follows: When in use, the heat spreader is placed on the placement platform 9 and fixed by the pre-pressing mechanism 10 to ensure the stability of the welding process; the screw motor 7 is started in forward rotation mode, and the feeding screw 6 drives the screw seat 8 and the placement platform 9 on it to move toward the welding head on the welding machine body 1. After the welding is completed, the feeding screw 6 is started in reverse to move the processed heat spreader out for easy unloading.

[0059] During use, if it is necessary to adjust the distance between the two elbow clamps 15 according to the different widths of the heat exchange plate, the operator can directly push the linear slide 14 towards the placement platform 9. At this time, due to the inclined action of the triangular block 21 and the triangular hole 17, the triangular block 21 will be squeezed and forced to disengage from the triangular hole 17 (the return spring 23 is compressed). At the same time, the moving rod 20 slides on the support column 19. When the appropriate position is reached, the pushing is stopped. At this time, the triangular block 21 is reset due to the elastic force of the return spring 23 and inserted into the corresponding triangular hole 17, thereby completing the distance adjustment. The operation is convenient and quick.

[0060] Furthermore, when adjusting the spacing, the operator places their thumb on the operating plate 27 and their other four fingers on the auxiliary plate 25, and pinches it slightly to move the moving rod 20 toward the linear slide 14, thereby disengaging the triangular block 21 from the triangular locking hole 17 (the return spring 23 is compressed). During this process, the linear slide 14 can be moved (the toggle clamp 15 moves away from the placement platform 9), thus facilitating adjustment and use.

[0061] In addition, if the rubber pressure head 28 is damaged after long-term use, it can be directly removed and a new rubber pressure head 28 can be installed through the buckling structure of the mounting rod 29, the retaining ring 30 and the annular groove 32, which is convenient to use. The setting of the rubber pressure head 28 can not only tightly fix the heat exchange plate, but also prevent surface scratches.

[0062] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
