Abstract
Description
Technical Field
[0001] This application relates to the field of welding technology, and more particularly to a handheld welding machine. Background Technology
[0002] Welding is a crucial step in modern industrial production and various manufacturing processes. Handheld welding machines, due to their flexibility and adaptability to diverse and complex working environments, are widely used in numerous industries such as automobile manufacturing, electronic equipment assembly, and hardware processing.
[0003] However, traditional handheld welding machines typically have a fixed welding torch structure, and their handheld parts lack an effective adjustment mechanism. When operators need to weld workpieces at different positions and angles, the inability to flexibly rotate and adjust the position of the welding torch often requires operators to significantly adjust their posture or even move the entire welding equipment. This not only greatly increases the operator's workload and reduces work efficiency, but also makes it impossible to achieve the ideal welding position and angle in some space-constrained work scenarios, resulting in difficulty in guaranteeing welding quality.
[0004] Based on the above reasons, this utility model proposes a handheld welding machine that can adjust the welding gun of the handheld welding machine at multiple angles and positions, thereby effectively ensuring high-quality welding under various complex working conditions. Utility Model Content
[0005] In view of the above problems, this application provides a handheld welding machine to solve the problem of inconvenience in welding of existing handheld welding machines.
[0006] This application provides a handheld welding machine, including a welding machine main unit and a welding torch.

Two movable rods are movably connected to the annular plate. A locking assembly is provided on the annular plate. The bottom ends of the two movable rods are fixedly connected to the same movable ring. A mounting shell is movably connected to the movable ring. An adjustable handle is provided on the mounting shell. A control button is installed on the adjustable handle.

[0028] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0029] like Figure 1-5 As shown, this application provides a handheld welding machine, including a welding machine host 1 and a welding torch 2. The welding machine host 1 and the welding torch 2 are connected by a connecting cable 3, which can realize the welding function.
[0030] like Figure 3 and Figure 5 As shown, an annular plate 4 is fixedly connected to the welding torch 2, and two movable rods 5 are movably connected to the annular plate 4. A locking assembly 6 is provided on the annular plate 4. The locking assembly 6 includes a side groove 10. The annular plate 4 has a side groove 10 at the movable ring 7. A round shaft 11 is movably connected in the side groove 10. A pressure plate 12 is fixedly connected to the round shaft 11. A vertical plate 13 is fixedly connected to the side wall of the pressure plate 12. The pressure plate 12 has an elliptical cross section. An anti-slip pad 14 is fixedly connected to the outer side wall of the pressure plate 12.
[0031] In the technical solution of this embodiment, by pulling the movable rod 5, the movable rod 5 drives the movable ring 7 to move on the outer surface of the welding gun 2, which can adjust the hand-held part of the welding gun 2 to ensure that the head of the welding gun 2 meets the welding needs of different positions. By pushing the vertical plate 13, the vertical plate 13 drives the pressure plate 12 to rotate around the circular shaft 11, and the pressure plate 12 clamps the side wall of the movable rod 5, which can realize the positioning of the movable rod 5 and facilitate welding.
[0032] Furthermore, the top ends of the two movable rods 5 are fixedly connected to the same horizontal plate 26. The center of the horizontal plate 26 has a through hole that matches the connecting line 3. The connecting line 3 passes through the through hole. The horizontal plate 26 can limit the position of the connecting line 3, reduce the impact of adjustment on the connecting line 3, and improve the ease of use.
[0033] like Figure 4 As shown, the bottom ends of the two movable rods 5 are fixedly connected to the same movable ring 7. The movable ring 7 is movably connected to the mounting shell 8. The mounting shell 8 is provided with an adjustable handle 9. The adjustable handle 9 is equipped with a control button 17. The adjustable handle 9 includes a fixed shaft 15. The fixed shaft 15 is movably connected to the mounting shell 8 and a movable plate 16 is fixedly connected to its side wall. The movable plate 16 is fitted with a movable shell 18. The side wall of the movable shell 18 is threaded with a clamping bolt 23. One end of the clamping bolt 23 is pressed against the outer wall of the movable plate 16. The movable plate 16 is located on one side of the inner cavity of the mounting shell 8 and is arc-shaped. Several first slots 19 are opened on the side wall. Several second slots 20 are evenly distributed on the outer side wall of the movable ring 7. A circular groove is opened on the inner side of the mounting shell 8. A spring 21 is provided in the circular groove. Positioning rods 22 are fixedly connected to both ends of the spring 21. The ends of the two positioning rods 22 away from the spring 21 are respectively inserted into the first slot 19 and the second slot 20.
[0034] In the technical solution of this embodiment, during the actual welding process, by rotating the mounting shell 8 on the movable ring 7, the handheld part of the welding gun can be rotated and adjusted to a specified position. The positioning rod 22 is inserted into the second slot 20 to achieve positioning between the mounting shell 8 and the movable ring 7, reducing the influence of the welding gun 2 structure on the welding operation. By pulling the movable shell 18, the length of the movable plate 16 extending out of the movable shell 18 is changed. The positioning between the movable shell 18 and the movable plate 16 is completed by rotating the clamping bolt 23, making it convenient for different personnel to operate the handheld part. Then, by rotating the movable plate 16, the movable plate 16 rotates around the fixed axis 15. The positioning rod 22 is inserted into the first slot 19 to achieve positioning of the movable plate 16 at a specified angle, which facilitates welding operations at different handheld angles and further improves the convenience of welding.
[0035] Furthermore, annular grooves 24 are provided on both the upper and lower side walls of the movable ring 7, and a slide rail 25 is fixedly connected to the mounting shell 8. The slide rail 25 is movably connected to the annular groove 24, which allows the mounting shell 8 to rotate stably on the movable ring 7, making it convenient for adjustment and use.
