Therefore, the above terms should not be construed as limitations on this application.

[0020] Example 1: This embodiment provides an adjustment device for a welding torch, such as... Figures 1-4 As shown, the device includes a housing 1 connected to a welding torch holder and a movable block 2 connected to a welding torch. The housing 1 contains a movable cavity 3, with at least a portion of the movable block 2 located within the cavity 3. At least three steel balls 4 and at least one spring 5 are respectively disposed on opposite sides of the movable cavity 3. The two ends of the spring 5 are respectively attached to the cavity wall of the movable cavity 3 and one side of the movable block 2. The two ends of the steel balls 4 are respectively attached to the cavity wall of the movable cavity 3 and the other side of the movable block 2. In this embodiment, twelve steel balls 4 are evenly distributed around the center of the movable block 2, with their tops on the same horizontal plane. This ensures that the movable block 2 receives uniform support during movement, reducing frictional resistance and improving the smoothness and flexibility of its movement. This even distribution also better disperses the external forces acting on the movable block 2, extending the service life of both the movable block 2 and the steel balls 4. The twelve springs 5, evenly distributed around the center of the movable block 2, provide a stable and omnidirectional elastic force to the movable block 2. In this embodiment, the steel balls 4 can also be replaced by components with a hemispherical or arc-shaped top surface.

[0021] The movable cavity 3 provides space for the installation and movement of the movable block 2, allowing the block 2 to move within it. The steel balls 4 provide support for the movable block 2; their spherical shape reduces the contact area with the block 2, ensuring smooth movement. The steel balls 4 also move smoothly. The three steel balls 4 are in close contact with the movable block 2, forming a surface that allows the block 2 to slide on a plane, providing good stability. The spring 5 provides pressure to the movable block 2, ensuring reliable contact between the block 2 and the steel balls 4, while preventing free movement, such as movement due to inertia during operation. This ensures the block 2 can only adjust when the welding torch is subjected to external force. Through the cooperation of the steel balls 4 and the spring 5, the movable block 2 can move freely while also being subject to appropriate pressure constraints, ensuring the stability and precise adjustment of the welding torch during use. During the welding torch operation, when the position of the welding torch is about to shift and become misaligned with the welding position, the movable block 2 is moved by force, so that the welding torch and the welding position remain fixed. The misalignment is offset by the relative movement of the movable block 2 and the housing 1. That is, the positions of the welding torch fixing frame and the housing 1 shift, while the movable block 2 keeps the welding torch in the correct welding position.

[0022] To ensure reliable installation of spring 5, the movable cavity 3 is provided with a first mounting groove 6 that mates with spring 5, and the movable block 2 is provided with a second mounting groove 7 that mates with the first mounting groove 6. The two ends of spring 5 are respectively located on the first mounting groove 6 and the second mounting groove 7. The cooperation of the first mounting groove 6 and the second mounting groove 7 not only provides a mounting position for spring 5 but also effectively prevents spring 5 from shifting or falling off during operation, ensuring reliable operation. After the two ends of spring 5 are bound by the first mounting groove 6 and the second mounting groove 7, the movable block 2 slides horizontally during operation, causing the upper and lower ends of spring 5 to shift. After operation, spring 5 automatically resets, simultaneously bringing the movable block 2 back to its original position, ensuring the welding torch remains in the center position when not subjected to external force. During welding torch operation, the twelve springs 5 ​​work together, being compressed or stretched accordingly based on the direction and distance of movement of the movable block 2, thereby adjusting the magnitude and direction of the elastic force on the movable block 2 in real time, further ensuring the smooth movement of the movable block 2 and the precision of welding torch adjustment.

[0023] To ensure reliable installation of spring 5, both the first mounting groove 6 and the second mounting groove 7 are circular grooves, and the diameters of the first mounting groove 6 and the second mounting groove 7 are matched with the outer diameter of spring 5. During installation, spring 5 can fit tightly against the inner walls of the first mounting groove 6 and the second mounting groove 7, preventing spring 5 from shaking or causing unnecessary displacement within the grooves, thereby improving the stability of spring 5 installation. The circular groove design also facilitates processing and manufacturing, reducing production costs and improving production efficiency.

[0024] To ensure reliable installation of the steel ball 4, the movable cavity 3 is provided with a third mounting groove 8 that mates with the steel ball 4. The steel ball 4 is located on the third mounting groove 8, with its top outside the groove. The design of the third mounting groove 8 allows for positioning and fixing of the steel ball 4, facilitating its installation, while also limiting its movement to ensure its proper position within the movable cavity 3.

[0025] To ensure reliable movement of the movable block 2, the steel balls 4 are evenly distributed around the center of the movable block 2, and the maximum distance between the two third mounting slots 8 is less than the diameter of the movable block 2. The even distribution of the steel balls 4 around the center of the movable block 2 forms a stable support structure, ensuring that the movable block 2 experiences uniform force during movement and will not tilt. The diameter of the movable block 2 is greater than the maximum distance between the two opposing third mounting slots 8, and a distance is also maintained between the top of the steel balls 4 and the wall of the third mounting slot 8, ensuring that the movable block 2 will not exceed the steel balls 4 during small-range movements, thus guaranteeing the support of the steel balls 4 for the movable block 2.

[0026] To ensure the reliability of the movable block 2, the movable block 2 includes a sliding part 9 and a connecting part 10 connected to the welding torch. The sliding part 9 is located inside the movable cavity 3, and its two sides are respectively in contact with the steel ball 4 and the spring 5; the second mounting groove 7 is located on the sliding part 9. The sliding part 9 is used to control movement, and the connecting part 10 is used to connect with the welding torch. The two functional parts are separated to reduce mutual influence.

[0027] To facilitate connection with the welding torch, the housing 1 has a notch 11 through which the connecting part 10 extends out of the housing 1. Both the sliding part 9 and the connecting part 10 are cylindrical, with the diameter of the sliding part 9 being larger than the diameter of the notch 11. The notch 11 is designed to facilitate the extension of the connecting part 10 for connection and fixation with the welding torch. The cylindrical structure ensures balanced weight distribution in all directions, making the movement of the movable block 2 stable. The large diameter of the sliding part 9 prevents it from dislodging from the notch 11.

[0028] To control the adjustment range of the welding torch, a welding torch connector 12 is also included. The movable block 2 is fixedly connected to the welding torch connector 12. The welding torch connector 12 is provided with a limiting groove 13, and the housing 1 is provided with a limiting rod 14 that mates with the limiting groove 13. One end of the limiting rod 14 is fixedly connected to the housing 1, and the other end is located on the limiting groove 13. The limiting rod 14 is connected to the movable block 2 by threads, that is, a threaded hole is provided on the movable block 2, and part of the limiting rod 14 is installed in conjunction with the threaded hole. The welding torch connector 12 is used to connect with the welding torch; the limiting groove 13 and the limiting rod 14 cooperate to limit the movement range of the movable block 2, thereby controlling the adjustment range of the welding torch and preventing the welding torch from moving too far, which would affect the welding effect.

[0029] To ensure reliable positioning, two limiting grooves 13 are symmetrically arranged relative to the movable block 2; the distance between the groove wall of the limiting groove 13 and the circumferential surface of the limiting rod 14 is 2mm. The symmetrical arrangement of the limiting grooves 13 improves the positioning effect, preventing the movable block 2 from shifting due to unilateral positioning, thus enhancing the stability and reliability of the positioning. Setting the distance between the groove wall of the limiting groove 13 and the circumferential surface of the limiting rod 14 to 2mm limits the adjustment range of the welding torch to 2mm, ensuring both sufficient adjustment space for the welding torch and guaranteeing its welding accuracy.

[0030] To ensure the structural reliability of the housing 1, the housing 1 includes an upper shell 15 and a lower shell 16, which are connected by bolts. A first mounting groove 6 is located in the upper shell 15, and a third mounting groove 8 is located in the lower shell 16. The upper shell 15 is bolted to the welding torch holder, the welding torch connector 12 is bolted to the welding torch, and the welding torch connector 12 is bolted to the movable block 2. The bolted connection between the upper shell 15 and the lower shell 16 provides high connection strength, facilitates disassembly and assembly, and enables convenient assembly and subsequent maintenance.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
