[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] In the description of this utility model, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used to distinguish the description and should not be construed as indicating or implying relative importance.

[0021] Example: like Figure 1-4As shown, the quick-change gun device for automated welding equipment proposed in this embodiment includes a worktable 1, a support 2 fixedly connected to the upper surface of the worktable 1, and a placement platform 16 fixedly installed on the upper surface of the worktable 1. The workpiece to be welded is placed on the top of the placement platform 16. A servo motor 3 is fixedly installed on the lower surface of the support 2. A connecting shaft 4 is fixedly connected to the output end of the servo motor 3. A first connecting plate 5 is horizontally arranged at the end of the connecting shaft 4 away from the servo motor 3. The end of the connecting shaft 4 away from the servo motor 3 is fixedly connected to the center of the lower surface of the first connecting plate 5. Both ends of the bracket 2 are hinged with second connecting plates 6. Two symmetrically distributed guide rails 7 are fixedly connected to the upper surface of the bracket 2. Slide blocks 8 are slidably connected to the guide rails 7. The ends of the two second connecting plates 6 away from the first connecting plate 5 are respectively rotatably connected to the two slide blocks 8. When the servo motor 3 is started, the connecting shaft 4 and the first connecting plate 5 are rotated clockwise by the servo motor 3. This causes the two slide blocks 8 to slide on the two guide rails 7 respectively through the two second connecting plates 6. A first through groove 9 is opened through each of the two guide rails 7. Two symmetrically distributed second through grooves 10 are opened through the bracket 2. A fixed shaft 11 is fixedly connected to the lower surface of the slide block 8, and a mounting plate 12 is fixedly connected to the bottom of the fixed shaft 11. The two slide blocks 8 move in opposite directions and move away from each other. At the same time, the two mounting plates 12 move in opposite directions and move away from each other through the two fixed shafts 11. A large welding torch 13 and a small welding torch 14 are fixedly mounted on the bottom of the two mounting plates 12, respectively. Two storage shells 15 are fixedly connected to the lower surface of the bracket 2. The two storage shells 15 are symmetrically distributed about the central axis of the bracket 2. Limit plates are fixedly connected to the front end faces of the two guide rails 7. 17. The upper surface of the limiting plate 17 is located above the guide rail 7, and the placement platform 16 is located directly below the two limiting plates 17. The large welding gun 13 moves forward and disengages from one of the storage shells 15, while the small welding gun 14 moves away from the limiting plate 17 and moves into the other storage shell 15. Conversely, when the servo motor 3 drives the connecting shaft 4 and the first connecting plate 5 to rotate counterclockwise, the large welding gun 13 moves away from the limiting plate 17, and the small welding gun 14 moves forward, thereby enabling rapid automatic switching between the large welding gun 13 and the small welding gun 14.

[0022] like Figure 1 and Figure 2 As shown, the two second through slots 10 are located directly below the two first through slots 9, and the two second through slots 10 are connected to the two first through slots 9. The fixed shaft 11 is located in the first through slot 9 and the second through slot 10. Through the two first through slots 9 and the two second through slots 10, when the two slides 8 move, the two fixed shafts 11 can be guaranteed to move smoothly and synchronously with the two slides 8.

[0023] The working principle of the above embodiment is as follows: The servo motor 3 is electrically connected to an external control power supply. First, the workpiece to be welded is placed on top of the placement platform 16. The servo motor 3 is started. When the servo motor 3 drives the connecting shaft 4 and the first connecting plate 5 to rotate clockwise, the two second connecting plates 6 drive the two slide blocks 8 to slide on the two guide rails 7 respectively. The two slide blocks 8 move in opposite directions and move away from each other. At the same time, the two fixed shafts 11 cause the two mounting plates 12 to move in opposite directions and move away from each other, thereby moving the large welding torch 13 forward. The large welding gun 13 detaches from one of the storage shells 15, while the small welding gun 14 moves away from the limiting plate 17 and moves into another storage shell 15. Conversely, when the servo motor 3 drives the connecting shaft 4 and the first connecting plate 5 to rotate counterclockwise, the large welding gun 13 moves away from the limiting plate 17, and the small welding gun 14 moves forward. This enables rapid and automatic switching between the large welding gun 13 and the small welding gun 14, which greatly improves the efficiency of changing guns compared to manual gun changing. Depending on the actual processing requirements, the large welding gun 13 or the small welding gun 14 can be selected to automatically weld the workpiece on the placement table 16.

[0024] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
