[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0021] A high-efficiency laser welding device for stainless steel ducts includes a laser welding machine body 1, a worktable 8, and a welding torch 3. The worktable 8 is connected to the body 1, and the body 1 is connected to a connecting cable 7, which is connected to the welding torch 3. A protective structure is provided on the worktable 8, and the welding torch 3 is located within the protective structure. Through the protective structure, workers are less likely to be burned by the welding torch 3.
[0022] The protective structure includes a retaining ring 18, a retaining frame 17, and a heat shield 4. The retaining frame 17 is mounted on the workbench 8, and the retaining rings 18 are fixedly mounted on the retaining frame 17. Multiple retaining rings 18 are mounted on the retaining frame 17. A snap-fit ring 6 is provided on the workbench 8. The welding torch 3 includes a handle 11 and a torch head 15. The torch head 15 is inserted into the retaining ring 18, and the handle 11 is snapped into the snap-fit ring 6.
[0023] Two locking rings 6 are provided on the worktable 8, and the two locking rings 6 are respectively located at both ends of the handle 11. The two locking rings 6 improve the stability of the handle 11 on the worktable 8. Multiple retaining rings 18 can improve the stability of the welding torch 3's torch head 15 within the retaining rings 18, making the torch head 15 less prone to shaking within the retaining rings 18.
[0024] The heat shield 4 is detachably mounted on the machine body 1. The fixing ring 18 and the gun head 15 are located between the workbench 8 and the heat shield 4. The heat shield 4 serves to isolate the gun head 15, preventing the high-temperature welding gun head 15 from burning the workers. The heat shield 4 has a hollow structure, which creates an air layer in the heat insulation layer. Since the thermal conductivity of air is lower than that of solid materials, the heat insulation effect of the heat shield 4 is better.
[0025] The workbench 8 is provided with two insertion slots 5, and the fixing bracket 17 is located between the two insertion slots 5. The heat insulation cover 4 is fixedly connected with an insertion strip 19, which is inserted into the insertion slot 5. The arrangement of the insertion strip 19 and the insertion slot 5 allows the heat insulation cover 4 to be detachably mounted on the workbench 8.
[0026] A fixing plate 14 is fixedly connected to the bottom of the heat insulation cover 4. The fixing plate 14 is located between two insertion slots 5. The fixing plate 14 is threadedly connected to a threaded rod 13. There are two threaded rods 13 on the fixing plate 14, and the threaded rods 13 are threadedly connected to the worktable 8. After the insertion strip 19 of the heat insulation cover 4 is inserted into the insertion slot 5, the threaded rod 13 further fixes the heat insulation cover 4 to the worktable 8, increasing the installation stability of the heat insulation cover 4 on the worktable 8.
[0027] The locking ring 6 has a U-shaped structure, with limiting blocks 9 fixedly connected to both ends of the locking ring 6. The two limiting blocks 9 are set at the ends of the locking ring 6 and are made of elastic material. The shape of the locking ring 6 makes the handle 11 of the welding torch 3 stably locked in the locking ring 6, while the limiting blocks 9 make it difficult for the handle 11 to fall off the locking ring 6 without external force.
[0028] The snap-fit ring 6 includes a first ring 10 and a second ring 12. The first ring 10 is fixedly connected to the worktable 8, and is located between the fixed frame 17 and the second ring 12. A movable block 16 is fixedly connected to the second ring 12. A movable groove 2 is provided on the worktable 8, and the movable block 16 is slidably connected in the movable groove 2. By setting up the movable block 16 and the movable groove 2, the distance between the two snap-fit rings 6 can be adjusted for convenient use.
[0029] The implementation principle of this embodiment is as follows: When in use, the welding torch 3 is placed in the protective structure, so that the torch head 15 of the welding torch 3 is inserted into the fixing ring 18, and the handle 11 is locked in the locking ring 6. At this time, the welding torch 3 is stably placed on the protective structure, and the high temperature of the welding torch head 15 is isolated between the workbench 8 and the heat insulation cover 4, so that the workers are not easily burned by the high temperature of the welding torch head 15, thus achieving the effect that the workers are not easily burned.
