[0023] Reference Figures 1 to 5 The welding device includes: a welding torch 1, an adjusting assembly, a platform 2, a gantry frame 3, and a clamping assembly; the clamping assembly is connected to the top surface of the platform 2 and can horizontally clamp and fix the workpiece to be welded; the gantry frame 3 is horizontally fixed to the top surface of the platform 2 and located above the clamping assembly; the adjusting assembly includes: a circular track 4 with its top connected to the bottom surface of the crossbeam of the gantry frame 3 and extending vertically downward, a first slider 5, and a fastening bolt 6; the first slider 5 can slide along the circular track 4 and the plane of the sliding trajectory is perpendicular to the workpiece to be welded held by the clamping assembly; the fastening bolt 6 is threadedly engaged with the middle part of the top of the first slider 5 and can fix the first slider 5 on the circular track 4; the welding torch 1 is connected to the bottom end of the first slider 5 and located above the welding point of the workpiece to be welded.
[0024] The working principle of the welding device is as follows: First, the workpiece to be welded is placed in the clamping assembly for fixation. Then, according to the welding requirements of the area to be welded, the first slider 5 is slid along the circular track 4, thereby driving the welding gun 1 connected to the bottom of the first slider 5. After the welding gun 1 is adjusted to a suitable welding angle, the welding gun 1 is fastened to the circular track 4 by the fastening bolt 6. At this time, the welding gun 1 can be opened to weld the workpiece below it. After one part of the workpiece to be welded is heated and melted and welded, the fastening bolt 6 can be loosened to release the first slider 5, and the first slider 5 can be slid to another place on the circular track 4 to weld the other part of the workpiece.
[0025] By continuously adjusting the welding angle of the welding torch 1, the welding area of the workpiece can be heated and melted from multiple angles. This eliminates the need for operators to frequently adjust their posture or the position of the workpiece, reducing operational difficulty, improving welding efficiency, and ensuring the aesthetics and process requirements of the weld.
[0026] Reference Figure 1 , Figure 4 , Figure 5 The welding device also includes a second slider 7. A horizontal cross-shaped groove 31 with a cross-shaped cross section is provided on the crossbeam of the gantry frame 3, which runs through the upper and lower parts of the crossbeam. The direction of the cross groove 31 is perpendicular to the workpiece to be welded held by the clamping assembly. The top end of the second slider 7 is fitted and slidably connected in the cross groove 31, and the bottom end of the second slider 7 passes downward through the cross groove 31 and is connected to the top end of the circular track 4. Thus, the position of the welding gun 1 can be adjusted in the transverse direction perpendicular to the workpiece to be welded. Combined with the adjustment assembly, the welding angle can be adjusted at various positions of the workpiece to be welded, further ensuring the welding quality.
[0027] Reference Figure 1 , Figure 4 , Figure 5 The welding device also includes: a motor 8, a lead screw 9, and a lead screw seat 10. The lead screw seat 10 is fixedly connected to the top surface of the crossbeam of the gantry frame 3.

The top end of the second slider 7 is also connected to a nut 71 that engages with the lead screw 9. The above-mentioned transmission mechanism can enable the second slider 7 to move automatically and uniformly along the cross groove 31, thereby driving the welding torch 1 to move automatically and uniformly at the welding point of the workpiece to be welded, ensuring that the welding point is heated and melted evenly, thereby ensuring the welding quality.
[0028] The welding device also includes a vertically arranged electric push rod 11 and two telescopic rods 12 located on both sides of the electric push rod 11. The top ends of the electric push rod 11 and the two telescopic rods 12 are connected to the top end of the second slider 7, and the bottom ends of the electric push rod 11 and the two telescopic rods 12 are connected to the top end of the circular track 4. The above-mentioned lifting mechanism can flexibly adjust the height of the welding torch 1. During welding, the electric push rod 11 and the telescopic rods 12 on both sides can be lowered to be close to the welding point. After welding is completed, the electric push rod 11 and the telescopic rods 12 on both sides can be raised to remove the welded part from the clamping assembly. At the same time, it can also be lowered by different distances according to different sizes of the welded parts.
[0029] Reference Figure 1 , Figure 4 , Figure 5 The welding device also includes a slide plate 13, which includes a horizontal slide plate body 131 and third sliders 132 connected to the lower sides of the slide plate body 131. A clamping assembly is connected to the top surface of the slide plate body 131.

The top of the first slider 5 has arc-shaped portions 51 on the front and rear sides that can be fitted and slidable in the first circumferential grooves 411 and the second circumferential grooves 421. The above structural design allows the first slider 5 to slide smoothly in the first circumferential grooves 411 and the second circumferential grooves 421, while ensuring that the first slider 5 will not slip off the circular track 4.
[0033] The adjustment assembly also includes a stop plate 20, which is horizontally and fixedly connected to the fastening bolt 6. The stop plate 20 is located in the inner ring space of the front ring track 41 and the rear ring track 42 to provide a more reliable braking locking force, while facilitating the rotation of the fastening bolt 6.
