[0002] Currently, the main function of finned tubes is to increase the heat-receiving surface (or heat dissipation) and improve heat transfer efficiency. Finned tubes consist of fins and heat pipes, with the fins being welded to the heat pipes for fixation.

[0004] However, the above structure still has shortcomings. First, the device is cumbersome to operate and affects production efficiency by changing the installation rollers to adapt to different specifications of finned tubes. Second, during welding, workers still need to hold a welding gun to weld the fins, which is inconvenient.

[0005] Therefore, it is necessary to provide a new welding device for finned tubes to solve the above-mentioned technical problems. Utility Model Content

[0025] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the overall structure of the welding finned tube welding device provided by this utility model; Figure 2 This is a three-dimensional structural diagram of the clamping mechanism in this utility model; Figure 3 This is a three-dimensional structural diagram of the welding mechanism in this utility model; Figure 4 This is a side view of the welding mechanism in this utility model. The welding device for finned tubes includes: a base plate 1, on which a rotating mechanism, two clamping mechanisms, a moving mechanism, and a welding mechanism are provided;

[0026] The rotating mechanism includes two vertical plates 2, two turntables 3 and a first motor 4. The two vertical plates 2 are fixedly installed on the top of the base plate 1. The two turntables 3 are respectively rotatably installed on the side of the two vertical plates 2 that are close to each other. The first motor 4 is fixedly installed on the corresponding vertical plate 2. The output shaft of the first motor 4 is fixedly connected to the corresponding turntable 3.

[0027] The clamping mechanism includes two strip plates 5, a bidirectional threaded rod 6, a second motor 7, two internally threaded sliding plates 8, and two sliders 9. The two strip plates 5 are fixedly mounted on the turntable 3. The bidirectional threaded rod 6 is rotatably mounted on the two strip plates 5. The second motor 7 is fixedly mounted on the top of the corresponding strip plate 5. The output shaft of the second motor 7 is fixedly connected to the bidirectional threaded rod 6. The two internally threaded sliding plates 8 are threaded onto the bidirectional threaded rod 6. The two sliders 9 are respectively fixedly mounted on the two internally threaded sliding plates 8.

[0028] like Figure 1 As shown, the moving mechanism includes a one-way threaded rod 10, a third motor 11, a column 12, and a crossbar 13. The one-way threaded rod 10 is rotatably mounted on two vertical plates 2. The third motor 11 is fixedly mounted on the corresponding vertical plate 2. The output shaft of the third motor 11 is fixedly connected to the one-way threaded rod 10. The column 12 is threaded onto the one-way threaded rod 10. The crossbar 13 is fixedly mounted on one side of the column 12.

[0029] The third motor 11 drives the unidirectional threaded rod 10 to rotate clockwise or counterclockwise, thereby driving the cross frame 13 and the welding mechanism to move synchronously, realizing continuous welding of the welding mechanism along the axial direction of the fin tube, and meeting the needs of welding multiple places on a single fin.

[0030] like Figure 3 As shown, the welding mechanism includes a first electric telescopic rod 14, a mounting plate 15, two rectangular plates 16, two second electric telescopic rods 17, two rectangular blocks 18, and two welding heads 19. The first electric telescopic rod 14 is fixedly mounted on the crossbeam 13. The mounting plate 15 is fixedly mounted on the output shaft of the first electric telescopic rod 14. The two rectangular plates 16 are both fixedly mounted on the bottom of the mounting plate 15. The two second electric telescopic rods 17 are respectively fixedly mounted on the two rectangular plates 16. The two rectangular blocks 18 are respectively fixedly mounted on the output shafts of the two second electric telescopic rods 17. The two welding heads 19 are respectively fixedly mounted on the bottom of the two rectangular blocks 18.

[0031] By extending and retracting the first electric telescopic rod 14 and the second electric telescopic rod 17, the positions of the two welding heads 19 can be adjusted so that they are aligned with the connection points between the fins and the heat pipes on both sides, thereby achieving synchronous welding of the two welding heads, greatly improving welding efficiency, and ensuring the consistency of the weld seams on both sides of the fins.

[0032] like Figure 2 As shown, a guide groove is provided on the turntable 3, and two guide sliders are slidably installed in the guide groove. One side of each of the two guide sliders is fixedly connected to two internally threaded slide plates 8.

[0033] By sliding the guide groove and the guide slider together, the movement direction of the internal thread slide plate 8 can be restricted, preventing it from deflecting as the bidirectional threaded rod 6 rotates. This ensures that the internal thread slide plate 8 always moves along the straight line of the guide groove, thereby ensuring that the two sliders 9 move closer or further away synchronously, avoiding the fin tube from shifting during clamping and improving clamping stability.

[0034] like Figure 1 As shown, two guide slide rods are fixedly installed on the two vertical plates 2, and guide sliders are slidably sleeved on the two guide slide rods. One side of each guide slider is fixedly connected to the column 12.

[0035] The guide slide and guide slider work together to guide and support the movement of the column 12, preventing the column 12 from shaking or deflecting under the drive of the one-way threaded rod 10, ensuring the stability of the welding mechanism during movement, and thus ensuring the straightness and uniformity of the weld.

[0036] like Figure 2 As shown, both sliders 9 are provided with "V" shaped clamping grooves;

[0037] The "V" shaped clamping groove design utilizes the principle of triangle stability, allowing slider 9 to clamp and fix circular heat pipes of different diameters, thus improving the equipment's versatility.

[0038] The working principle of the welding finned tube welding device provided by this utility model is as follows:

[0039] First step: Weld the two ends of multiple fins evenly to the heat pipe in a ring shape, and place it between the "V" shaped clamping grooves of the two sliders 9. Start the second motor 7. The second motor 7 drives the bidirectional threaded rod 6 to rotate. Since the threads at both ends of the bidirectional threaded rod 6 rotate in opposite directions, the two internal threaded sliding plates 8 will drive the sliders 9 to move towards the middle in sync until the "V" shaped clamping grooves are tightly attached to the outer wall of the fin tube, thus completing the clamping and fixing of the fin tube.

[0040] Second step: Based on the height and width of the fins, activate the first electric telescopic rod 14 to adjust the height of the mounting plate 15 so that the welding head 19 is at the same vertical height as the welding position of the fins; activate the second electric telescopic rod 17 to adjust the distance between the two welding heads 19 so that the two welding heads 19 are respectively aligned with the connection points between the two sides of the fins and the heat pipes to ensure accurate welding position.

[0041] The third step: Start the welding head 19, and the third motor 11 drives the one-way threaded rod 10 to rotate, so that the column 12 drives the welding mechanism to move slowly along the axial direction of the fin tube, so as to realize continuous welding at different positions along the axial direction of the fin tube until the welding work of the entire fin tube is completed; then start the first electric telescopic rod 14 and the second electric telescopic rod 17 to reset the welding head 19, start the first motor 4 and the third motor 11, the first motor 4 drives the turntable 3 to rotate, so that the clamped fin tube rotates synchronously, and repeat the second step to weld the next fin.
