[0002] Circumferential welding is a continuous or segmented welding process used to weld the circumferential joint formed by the butt joint of two circular or annular workpieces, ultimately creating a closed circumferential weld. It is used to connect or seal workpieces and is commonly used in pipe connections and container manufacturing.

[0003] When workers are welding with a welding torch, the workpiece needs to be rotated as the position of the weld point changes in order to adjust the position of the weld point for subsequent welding. However, the workpiece is not completely welded and fixed. When rotating, the workpiece is affected by its weight and the rotation angle, which can easily cause the weld point to shift or even break, thus affecting the welding effect.

[0004] Therefore, it is necessary to provide a circumferential weld tooling to solve the above-mentioned technical problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment

[0018] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A circumferential welding fixture includes: a workbench 1, a positioning frame 12 on the workbench 1, a placement opening 11 in the middle of the workbench 1, an installation frame 2 placed in the placement opening 11, protective plates 21 symmetrically arranged on both sides of the installation frame 2, and a slide 22 on the protective plate 21. The mounting bracket 2 is equipped with a rotating wheel 3. A groove 31 is provided on the side wall of the rotating wheel 3, and the slide block 22 is slidably installed in the groove 31. A welding torch 4 is provided on the inner wall of the rotating wheel 3. The mounting bracket 2 is also equipped with a drive device 5, which is used to drive the rotating wheel 3 to rotate. During operation, the workpiece is placed on the positioning frame 12 for fixed positioning. Then, the welding torch 4 is started to weld the weld seam. At the same time, the drive device 5 is started, and the output end drives the rotating wheel 3 and the welding torch 4 to rotate. The rotating wheel 3 slides on the slide block 22 through the slide groove 31. The slide block 22 limits the rotating wheel 3 to prevent it from shaking or shifting when rotating. The rotating wheel 3 drives the welding torch 4 to rotate, so as to achieve the purpose of continuous welding of the annular weld seam without the need to rotate and adjust the workpiece, thus avoiding the displacement and breakage of the weld point during rotation.

[0019] Please refer to the following: Figure 2 and Figure 3 A rack 32 is provided on the outer wall of the rotating wheel 3, and the rack 32 is connected to the output end of the drive device 5; When the drive device 5 is started during operation, the output end drives the rotating wheel 3 to rotate through the rack 32, and the rotating wheel 3 drives the welding gun 4 to rotate to weld the workpiece.

[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The drive device 5 includes a motor 51 and a gear 52. The motor 51 is mounted on the protective plate 21. The output end of the motor 51 is provided with a gear 52. The gear 52 is rotatably mounted between the protective plates 21 and meshes with the rack 32. When working, the motor 51 is started, and the output end drives the gear 52 to rotate. The gear 52 drives the rack 32 and the rotating wheel 3 to rotate. The rotating wheel 3 drives the welding gun 4 to rotate to follow the position of the welding point, so there is no need to rotate the workpiece to adjust the position of the welding point.

[0021] Please refer to the following: Figure 2 , Figure 4 and Figure 5 A baffle 23 is also provided on the side of the protective plate 21 near the rotating wheel 3. The baffle 23 is used to prevent dust and debris from entering the protective plate 21. When the welding torch 4 is welding the workpiece, the baffle 23 blocks the falling welding slag and external dust, preventing the welding slag and dust from entering the protective plate 21 and falling into the slide groove 31 and rack 32, thus avoiding affecting the rotation of the rotary wheel 3.

[0022] Second Embodiment

[0023] Please refer to the following: Figure 4 and Figure 5 The circumferential welding fixture also includes an adjustment structure 6, which is installed on the inner wall of the rotary wheel 3. The welding torch 4 is installed on the adjustment structure 6, and the adjustment structure 6 is used to adjust the position of the welding torch 4. In this embodiment, after the workpiece is placed on the positioning frame 12, the distance between the welding torch 4 and the welding point on the workpiece surface varies with the change of the workpiece diameter. The distance between the welding torch 4 and the welding point is adjusted by the adjustment structure 6, which facilitates welding of workpieces with different diameters.

[0024] Please refer to the reference again. Figure 4 and Figure 5 The adjustment structure 6 includes a mounting box 61, a first push rod 62, a slider 63, and a second push rod 64. The mounting box 61 is mounted on the inner wall of the rotating wheel 3. The first push rod 62 is provided on the side wall of the mounting box 61. The slider 63 is provided at the output end of the first push rod 62. The slider 63 is slidably mounted in the mounting box 61. The second push rod 64 is mounted in the slider 63. The welding torch 4 is mounted on the output end of the second push rod 64. During operation, the first push rod 62 is activated first, and the output end drives the slider 63 to slide within the mounting box 61, moving the welding gun 4 above the welding point. Then, the second push rod 64 is activated, and the output end drives the welding gun 4 to move, adjusting the distance between the welding gun 4 and the welding point, thereby achieving the effect of adjusting the position of the welding gun 4, which is convenient for welding workpieces of different diameters.

[0025] Please refer to the following: Figure 1 and Figure 6 The bottom of the workbench 1 is also equipped with a lifting device 13, which is used to adjust the height of the workbench 1 and the positioning frame 12. When working, after placing the workpiece on the positioning frame 12 of the workbench 1, the lifting device 13 is started. The output end drives the workbench 1 and the workpiece to move up and down, so that the axis of the workpiece coincides with the axis of the rotating wheel 3, and the workpiece is positioned so that the distance between the welding torch 4 and the annular weld seam remains consistent, which facilitates the welding of the workpiece.

[0026] The working principle of the circumferential seam welding fixture provided by this utility model is as follows: During operation, after the workpiece is placed on the positioning frame 12 for fixed positioning, the motor 51 is started. The output end drives the gear 52 to rotate, which in turn drives the rack 32 and the rotating wheel 3 to rotate. The slide block 22 slides in the slide groove 31 to limit the rotating wheel 3. The rotating wheel 3 drives the welding torch 4 to rotate to the welding point position. The welding torch 4 then welds the weld seam, achieving continuous welding of the circumferential weld seam without the need to rotate or adjust the workpiece, thus avoiding weld point displacement and breakage during rotation. A first push rod 62 and a second push rod 64 are provided. During operation, the first push rod 62 is started first, and the output end drives the slider 63 to slide in the mounting box 61, moving the welding torch 4 above the welding point. Then, the second push rod 64 is started, and the output end drives the welding torch 4 to move, adjusting the distance between the welding torch 4 and the welding point, thus achieving the effect of adjusting the position of the welding torch 4, which is convenient for welding workpieces of different diameters.
