The connecting frame 101 is used to fix the welding wire tube 2, ensuring the stability of the welding wire tube 2 and enabling the welding wire 3 to be accurately delivered to the welding area. Two welding wire tubes 2 are fixedly connected inside the connecting frame 101, providing a delivery channel for the welding wire 3 and guiding it smoothly to the welding position. The welding wire 3 is fixedly installed inside the welding wire tube 2. An electrode sleeve 4 is fixedly connected to the bottom rear end of the mounting frame 1, fixing the electrode 5 and keeping it in a suitable position to ensure the arc. An electric arc is stably generated between electrode 5 and the workpiece. Electrode 5 is fixedly installed inside electrode sleeve 4. Electrode 5 generates an electric arc under the action of power supply. The high temperature generated by the electric arc is used to melt the welding wire 3 and the surface of the workpiece to achieve a welding connection. A wire feeding assembly 6 is installed at the front end of the mounting frame 1. The wire feeding assembly 6 is responsible for feeding the welding wire 3 to the welding area at a certain speed and rhythm. A moving assembly 8 is fixedly connected to the outer wall of the mounting frame 1. The moving assembly 8 is used to adjust the position and height of the welding device so that the welding operation can be accurately performed at different positions of the workpiece. The wire feeding assembly 6 includes a drive motor 601, a drive shaft 602, a gear 603, and... The concave wheel 604 and drive motor 601 are fixedly mounted on the outer wall of the mounting bracket 1. The drive motor 601 provides power for the rotation of the drive shaft 602, ensuring stable wire feeding. Two drive shafts 602 are movably mounted inside the mounting bracket 1. The drive shafts 602 are used to transmit power, driving the gear 603 and concave wheel 604 to rotate. One drive shaft 602 is fixedly mounted on the output end of the drive motor 601, transmitting the power of the drive motor 601 to the drive shaft 602. The gear 603 is fixedly connected to the outer wall of the drive shaft 602, and the gears 603 mesh with each other to achieve synchronous rotation of the two drive shafts 602, ensuring the two... The concave rollers 604 feed the welding wire 3 at the same speed. The two gears 603 mesh with each other. Through the meshing of the gears 603, the rotation of one drive shaft 602 can drive the other drive shaft 602 to rotate synchronously. The two concave rollers 604 are fixedly connected to the outer wall of the drive shaft 602. The two concave rollers 604 are located on both sides of the gears 603. The concave rollers 604 are used to clamp the welding wire 3. Through their own rotation, they drive the welding wire 3 to be fed forward.

The clamping force of the two corresponding concave rollers 604 is used to stably feed the welding wire 3, ensuring that the welding wire 3 will not deviate or jam during the feeding process.

[0031] The movable assembly 8 includes a mounting cylinder 801, a lead screw 802, a mounting block 804, a mounting base 805, and a movable ball 806. Two mounting cylinders 801 are fixedly connected to the outer walls of the mounting frame 1. The mounting cylinder 801 provides space for the lead screw 802 to be installed and slidably, ensuring stable movement of the lead screw 802. The lead screw 802 is slidably installed inside the mounting cylinder 801. The sliding of the lead screw 802 can drive the mounting block 804 to move up and down or horizontally. The mounting block 804 is fixedly connected to the bottom of the lead screw 802. The mounting block 804 is used to install the mounting base 805 and moves with the lead screw 802, driving the entire welding part to move. There are four mounting bases 805. Two mounting bases 805 are fixedly connected to the bottom of the mounting block 804. The mounting base 805 is used to install the movable ball 806, providing an installation position for the movable ball 806. The movable ball 806 is movably installed inside the mounting base 805, allowing it to move freely within the mounting base 805, contacting the workpiece surface, and providing support and assisting movement.

[0032] The mounting base 805 has an internal mounting groove, and the movable ball 806 is movably mounted inside the mounting groove. The mounting groove provides space for the movable ball 806 to move and restricts its range of motion, so that the movable ball 806 can rotate freely while ensuring the overall stability of the device. The bottom of the movable ball 806 contacts the top of the workpiece.

[0033] The moving assembly 8 also includes a rotating sleeve 803, a moving block 807, a slider 808, and a groove 809. The rotating sleeve 803 is movably installed at the bottom of the mounting cylinder 801. The rotating sleeve 803 is threaded into the inner wall of the mounting cylinder 801. By rotating the rotating sleeve 803, the lead screw 802 can move up and down, thereby adjusting the height of the welding device. The inner wall of the mounting cylinder 801 has threads corresponding to the lead screw 802. The threaded engagement is the key structure for realizing the up and down movement of the lead screw 802, ensuring the movement accuracy and stability of the lead screw 802. The moving block 807 is fixedly connected to the top of the lead screw 802. The moving block 807 is fixedly connected to the lead screw 802 and follows the movement. The lead screw 802 moves while simultaneously connecting to the slider 808, ensuring that the slider 808 and the lead screw 802 move synchronously. Multiple sliders 808 are fixedly connected to the outer wall of the moving block 807 in a ring shape. The slider 808 cooperates with the slide groove 809 to restrict the direction of movement of the lead screw 802, ensuring that the lead screw 802 can only move along the direction of the slide groove 809, thereby improving the stability of movement. Multiple slide grooves 809 are formed in a ring shape inside the mounting cylinder 801. The slider 808 is slidably installed inside the slide groove 809. The slide groove 809 provides a sliding track for the slider 808, making the movement of the lead screw 802 more stable and preventing the lead screw 802 from shaking or deviating during movement.

[0034] A power module 7 is fixedly installed at the top rear end of the mounting bracket 1. The power module 7 provides a stable power supply to the electrode 5, which is the energy guarantee for generating the electric arc, ensuring the stability and continuity of the electric arc during the welding process, and ensuring the normal progress of the welding work. The power output terminal of the power module 7 is connected to the two electrodes 5. The connection between the power module 7 and the electrodes 5 allows the current to pass smoothly through the electrodes 5, generating an electric arc between the electrodes 5 and the workpiece, and realizing the energy supply for welding.

[0035] A protective cover 9 is fixedly installed at the bottom of the mounting frame 1. The welding wire 3 and the electrode 5 are both located inside the protective cover 9. The protective cover 9 can effectively prevent spatter, strong light and other objects generated during the welding process from causing harm to the operator and the surrounding environment. At the same time, it can prevent external factors from interfering with the welding process, ensuring welding quality and operator safety.

[0036] Working principle: Before welding, the workpiece shape, thickness and welding process requirements are determined by rotating the rotating sleeve 803. When rotating the rotating sleeve 803, the screw 802 moves up and down inside the mounting sleeve 801 due to the threaded fit between the inner wall of the mounting cylinder 801 and the lead screw 802. The moving block 807, the slider 808 and the mounting block 804 also move up and down accordingly, thereby driving the entire welding part to rise or fall to achieve a suitable welding height, so that the moving ball 806 can fully contact the workpiece surface and adapt to the unevenness of the workpiece surface.

[0037] After the preparation is completed, start the drive motor 601. The drive motor 601 drives the drive shaft 602 connected to its output end to rotate. The gear 603 on the drive shaft 602 rotates accordingly. Since the two gears 603 mesh with each other, the other drive shaft 602 will also rotate synchronously. During the rotation, the concave wheel 604 on the two drive shafts 602 drives the welding wire 3 to be fed out of the welding wire tube 2 at a uniform speed through the clamping force.

[0038] After the power module 7 is powered on, current flows through the electrode 5, generating an electric arc between the electrode 5 and the workpiece. The high temperature generated by the electric arc melts the welding wire 3 and the surface of the workpiece. The molten welding wire fills the weld seam, achieving welding. During the welding process, the position of the welding device is adjusted by the moving component 8, and the mounting frame 1 is pushed or pulled, causing the lead screw 802 to slide inside the mounting cylinder 801, which drives the mounting block 804 and the welding part to move above the workpiece. The moving ball 806 rolls on the surface of the workpiece to ensure that the welding process proceeds along the predetermined welding path, while adapting to the unevenness of the workpiece surface, ensuring the stability and quality of the welding. During the welding process, the protective cover 9 always protects the welding wire 3 and the electrode 5 to prevent the welding spatter, strong light, etc. from affecting the surrounding area.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
