Description

Technical Field

[0001] This utility model relates to the field of plate radiator processing and manufacturing technology, and in particular to an electric welding device for plate radiators. Background Technology

[0002] Plate radiators are heat dissipation devices used in power transmission and transformation projects. They are usually made of cold-rolled steel plates and have a plate-like structure. By increasing the heat dissipation surface area, they effectively improve heat conduction and air convection efficiency, thereby reducing the operating temperature of the equipment. Plate radiators have a compact structure and low manufacturing cost. Depending on the requirements, they can be used with fans or heat pipes to enhance heat dissipation performance.

[0003] Electric welding of finned heat sinks has advantages such as strong welds and good thermal conductivity. This process can ensure uniform heat conduction between each heat sink fin, improve overall heat dissipation efficiency, and is suitable for mass production. It is widely used in power electronics, communication equipment and automotive electronics, and helps to improve product stability and lifespan.

[0004] Existing welding technology for finned radiators has advantages such as strong welds and good thermal conductivity. However, in actual processing, workers usually stack the fins directly to the base before welding. This method makes it difficult to ensure the positional accuracy of the fins during welding, which can easily lead to uneven fin spacing and poor welding stability, thus affecting the heat dissipation effect and overall quality of the finished finned radiator. Therefore, a welding device for finned radiators is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electric welding device for plate heat sinks, which aims to improve the existing technology of directly stacking heat sinks and bases for electric welding, which easily leads to uneven spacing between the plates and poor welding stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A welding device for finned radiators includes a base, with a movable platform and a fixed platform respectively provided on the top of the base. A distance adjustment component is installed at the bottom of the movable platform. A connecting frame is fixedly connected to the top of the movable platform and the fixed platform. An alignment plate is slidably connected to the side of the connecting frame. A quick-change component is installed inside the connecting frame. The quick-change component includes a slide rod, which is slidably connected inside the connecting frame. A locking block is fixedly connected to one end of the slide rod, and a rotary trigger is rotatably connected to the other end of the slide rod.

[0010] As a further description of the above technical solution:

[0011] The side of the alignment plate has a slot, and the locking block engages with the slot.

[0012] As a further description of the above technical solution:

[0013] The distance adjustment assembly includes a rotating rod, which is rotatably connected to the inside of the base. A gear is fixedly connected to the outside of the rotating rod. A rack and a guide plate are fixedly connected to the bottom of the moving platform. The gear and the rack mesh with each other.

[0014] As a further description of the above technical solution:

[0015] A motor is mounted on the side of the base, and the rotating rod is fixedly connected to the output end of the motor;

[0016] As a further description of the above technical solution:

[0017] The top of the base is provided with a guide groove, and the rack and the guide plate are slidably connected inside the guide groove;

[0020] As a further description of the above technical solution:

[0021] The side of the alignment plate is fixedly connected to a slider, and the inside of the connecting frame is provided with a sliding groove, and the slider is slidably connected inside the sliding groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the sliding rod moves inward by rotating the trigger, and the linkage block moves.

[0032] 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.

[0033] Reference Figures 1-3This utility model provides an embodiment of an electric welding device for a plate-type heat sink, including a base 1. A movable platform 2 and a fixed platform 3 are respectively provided on the top of the base 1. The movable platform 2 slides on the base 1, and the fixed platform 3 is fixed on the base 1. A distance adjustment component is installed at the bottom of the movable platform 2. A connecting frame 4 is fixedly connected to the top of the movable platform 2 and the fixed platform 3. An alignment plate 5 is slidably connected to the side of the connecting frame 4. A quick-change component is installed inside the connecting frame 4. The quick-change component includes a slide rod 6, which is slidably connected inside the connecting frame 4. Various structures are connected by the slide rod 6. A locking block 7 is fixedly connected to one end of the slide rod 6, and a rotating trigger 8 is rotatably connected to the other end of the slide rod 6. Pulling the rotating trigger 8 causes the slide rod 6 and the locking block 7 to move inward. A protective plate 9 is fixedly connected to the side of the connecting frame 4. The slide rod 6 is slidably connected inside the protective plate 9, using the protective plate 9 to protect the internal structure. A spring 10 is sleeved on the outer periphery of the slide rod 6, and the spring 10 is located between the locking block 7 and the protective plate 9. The pressure generated by the cooperation between the protective plate 9 and the spring 10 causes the slide rod 6 to move outward with the locking block 7. The side of the alignment plate 5 has a locking groove 11. The locking block 7 and the locking groove 11 are interlocked. The locking block 7 moves outward and locks into the locking groove 11, fixing the position of the alignment plate 5.

[0034] Reference Figure 1 , Figure 4 and Figure 5 The distance adjustment assembly includes a rotating rod 14, which is rotatably connected inside the base 1. The rotating rod 14 rotates within the base 1. A gear 15 is fixedly connected to the outer side of the rotating rod 14, causing the rotating rod 14 to rotate along with the gear 15. A rack 16 and a guide plate 17 are fixedly connected to the bottom of the moving platform 2. The moving platform 2 moves synchronously with the rack 16 and guide plate 17. The gear 15 meshes with the rack 16, and the rotating gear 15 controls the movement of the rack 16. A motor 18 is mounted on the side of the base 1, and the rotating rod 14 is fixedly connected to the output end of the motor 18. The motor 18 controls the rotation of the rotating rod 14, ultimately controlling the movement of the rack 16 and the moving platform 2.

[0035] Reference Figures 2-5 The top of the base 1 has a guide groove 19, and the rack 16 and guide plate 17 are slidably connected inside the guide groove 19. By setting the guide groove 19, the moving platform 2 is prevented from sliding out of the position of the base 1. The bottom of the moving platform 2 is provided with a pulley 20, which is slidably connected to the top of the base 1. By setting the pulley 20, the moving platform 2 can slide more smoothly, and at the same time, it can support the middle of the moving platform 2. The side of the alignment plate 5 is fixedly connected with a slider 12, and the inside of the connecting frame 4 has a sliding groove 13. The slider 12 is slidably connected inside the sliding groove 13. With the cooperation of the slider 12 and the sliding groove 13, the installation position of the alignment plate 5 is fixed.

[0036] Working principle: Pulling the rotary trigger 8 moves the slide bar 6 inward along with the locking block 7, then slides the slider 12 of the alignment plate 5 into the groove 13 of the connecting frame 4. Pulling the rotary trigger 8 in the opposite direction causes the locking block 7 to move outward under the pressure of the spring 10, locking it into the groove 11, thus completing the installation of the alignment plate 5. The base plate is then placed on the moving platform 2 and the fixed platform 3. The heat sink passes through the slot of the alignment plate 5 and is placed on the base plate. At this point, welding is performed, which ensures the uniformity of the heat sink spacing, improves welding stability, and enhances the quality of the finished plate heat sink.

[0037] The starting motor 18 drives the gear 15 to rotate via the rotating rod 14. The rotating gear 15 pushes the rack 16 to move in the guide groove 19 of the base 1. The rack 16 moves the moving platform 2, adjusting the distance between the moving platform 2 and the connecting frame 4 on the fixed platform 3. This adapts to the welding work of finned heat sinks of different lengths, improving the adaptability and compatibility of the welding device.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
