[0020] 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.

[0021] Please see Figure 1 , 2As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a fan duct welding device, comprising: a workbench, the workbench including a mounting plate 2 and a movable stage 14 slidably disposed at the end of the mounting plate 2; a fixing component disposed in the middle of the mounting plate 2, the fixing component including a positioning support plate 10 fixedly connected to the middle of the mounting plate 2 for fixing the fan, and a fixing pressure plate 9 for pressing the duct from the top is provided directly above the positioning support plate 10; welding parts 3 are distributed on the top of the mounting plate 2 and the movable stage 14 with the center of the positioning support plate 10 as the center, and the welding parts 3 have a horizontally movable welding torch 6.

[0022] It should be noted that the device of this utility model is equipped with a controller and a foot switch. The fan housing is fitted onto the outside of the positioning support plate 10, so that the air outlet of the fan is vertically upward. The end of the fan outlet located inside the housing is fitted onto the outside of the positioning support plate 10. Then, the air duct is installed at the air outlet position of the housing. The air duct is pressed down from the top by the fixing plate 9. Then, the moving table 14 is moved to the designated position by the control switch. The welding torch 6 is moved towards the air duct by the control switch, so that it is connected with the welding point for welding operation. After welding is completed, the moving table 14 slides to both sides while the fixing plate 9 moves upward, so that the welding torch 6 is separated from the air duct, making it easy to remove the workpiece.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, a support platform 1 is fixedly connected to the bottom of the mounting plate 2. The mounting plate 2 has an n-shaped structure. A movable platform 14 is symmetrically slidably connected to the end of the mounting plate 2. A T-shaped groove 11 is opened at the end of the mounting plate 2. A T-shaped block 15 is slidably connected inside the T-shaped groove 11. The T-shaped block 15 is fixedly connected to the movable platform 14. A cylinder 3 12 is fixedly connected to the bottom of the mounting plate 2. A connecting plate 13 is fixedly connected to the output end of the cylinder 3 12. The connecting plate 13 is fixedly connected to the movable platform 14.

[0024] It should be noted that when installing and removing materials from the fan housing and duct, the connecting plate 13 driven by the cylinder 3 12 moves, and the connecting plate 13 drives the moving table 14 to slide at one end of the mounting plate 2. During the sliding, the T-shaped block 15 slides inside the T-shaped groove 11, thereby controlling the moving table 14 to move to both ends and sides, preventing the welding torch 6 from being obstructed or posing a safety hazard when removing or installing materials.

[0025] Please see Figure 1 , 2 As shown in Figures 3 and 5, the fixing assembly also includes a bracket 7 fixedly attached to the top of the mounting plate 2. A cylinder 8 is fixedly connected to the middle of the bracket 7, and the output end of the cylinder 8 is fixedly connected to the fixing pressure plate 9.

[0026] It should be noted that in this utility model, the air outlet of the fan housing is sleeved from inside the fan onto the outside of the positioning support plate 10, and then the metal air duct is sleeved onto the outside of the air outlet of the fan housing. The cylinder 8 drives the fixing plate 9 to press down, so that the air duct can be tightly connected together, which facilitates subsequent welding.

[0027] Please see Figure 4 , 5 As shown, the welding part 3 also includes a support base 4 fixedly connected to the top of the mounting plate 2 and the moving table 14. A cylinder 5 is fixedly connected to the middle of the support base 4, and the output end of the cylinder 5 is fixedly connected to the welding gun 6.

[0028] It should be noted that, in this utility model, after the air duct is fixed to the fan housing, when the moving table 14 reaches the welding position, the cylinder 5 drives the welding torch 6 to move forward simultaneously, so that the welding torch 6 contacts the air duct and performs welding. After the welding is completed, the cylinder 5 is controlled to drive the welding torch 6 to separate from the air duct, thereby realizing simultaneous welding.
