Description

Technical Field

[0001] This utility model relates to the field of welding torch technology, and more specifically, to a rotatable welding device for welding torches. Background Technology

[0002] A welding torch utilizes the high current and high voltage of a welding machine to generate heat, which is concentrated at the tip of the torch, melting the welding wire. The molten wire penetrates the area to be welded, and after cooling, the welded objects are firmly joined together. Shafts and cylindrical parts are typically welded using a method where the welding torch is fixed and the part rotates. Manual welding can also be used, but for complex structures, medium to large-sized parts, or irregularly shaped parts, the limited position of the welding torch makes welding difficult, necessitating manual welding. However, the quality of manual welding is greatly affected by human factors, easily resulting in uneven welds, weld cracks, and other defects. Furthermore, manual welding has low efficiency, a harsh processing environment, and is unsuitable for mass production.

[0003] To address the aforementioned technical problems, Chinese patent CN221270156U discloses a welding head device, which includes a rotating module. The upper part of the rotating module is connected to a manual lead screw module, and the lower part is connected to a welding torch holder. The rotating module enables the welding torch to rotate 90°, i.e., rotate in the welding direction, without affecting the actual center position of the welding torch. Even if the center of the welding torch deviates after rotation, it can be corrected using the manual lead screw module.

[0004] Although the aforementioned device can rotate the welding torch by rotating the module, thus allowing the welding torch to rotate 90°, in actual welding processes, multiple parts of the same workpiece need to be welded. The welding angle also needs to be adjusted further beyond the 90° rotation. The processing range of the aforementioned patent is limited, and it cannot adapt to adjusting the welding angle for different welding parts, thus affecting the processing and application range of the welding torch. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a rotatable welding device for welding torches that can adjust the angle and welding height of the welding torch according to the changes in the position and angle of different welding parts on the workpiece, thereby expanding the processing range of the welding torch while ensuring welding quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rotatable welding device for a welding torch includes a fixed bracket, a rotating component mounted on the fixed bracket and an adjusting component connected to the rotating component, and a mounting bracket connected to the adjusting component.

[0014] By adopting the above technical solution, the relative position of the fine-tuning slide and the locking hole is adjusted according to the different welding angles, so that the angle between the rotating part and the rotating frame can be adjusted. After the angle adjustment is completed, the fastening bolt can be inserted through the fine-tuning slide and inserted into the locking hole for fastening, thereby fixing the angle between the rotating part and the rotating frame.

[0015] The present invention is further configured such that: a limiting frame is connected to the bottom of the rotating frame, and the welding torch is installed between the rotating frame and the limiting frame.

The slide plate 35 and the sliding bed 36 are mechanical slides. The slide plate 35 slides relative to the sliding bed 36 via a lead screw drive, and the sliding speed is adjusted by the action of a gearbox. The horizontal welding position is adjusted by the sliding of the slide plate 35 relative to the sliding bed 36. The bottom of the sliding bed 36 is provided with a connecting seat 37 that connects to the mounting bracket 4. The connecting seat 37 is fixedly connected to the mounting bracket 4, so that the mounting bracket 4 can move synchronously.

[0034] Please refer to Figure 1-4The mounting bracket 4 includes a connector 41 and a rotating component 42 connected to the adjusting assembly 3, a rotating frame 43 rotatably connected to the rotating component 42, and a welding torch 46.

A first connecting rod 411 is connected to the side wall of the connector 41, and a second connecting rod 431 is connected to the side wall of the rotating frame 43. A connecting spring rod 45 connects the first connecting rod 411 and the second connecting rod 431. Hooks are provided at both ends of the connecting spring rod 45, and the two hooks are respectively suspended on the first connecting rod 411 and the second connecting rod 431. During the rotation of the rotating frame 43 relative to the rotating component 42, the extension and retraction of the connecting spring rod 45 ensures a reliable connection between the rotating frame 43 and the connecting component 41. A fine-tuning groove 421 with an arc structure is provided on the side wall of the rotating component 42, located below the axis of rotation of the rotating component 42 and the rotating frame 43. A locking hole 432 is provided on the rotating frame 43 at a position corresponding to the fine-tuning groove 421. Depending on the welding angle, the relative position of the fine-tuning groove 421 and the locking hole 432 is adjusted to adjust the angle between the rotating component 42 and the rotating frame 43. After the angle adjustment, a fastening bolt can be inserted through the fine-tuning groove 421 into the locking hole 432 for tightening, thereby fixing the angle between the rotating component 42 and the rotating frame 43. A limit frame 44 is connected to the bottom of the rotating frame 43, and the limit frame 44 is fixedly connected to the rotating frame 43, allowing it to move synchronously with the rotating frame 43.

Specifically, one end of the welding gun 46 is fitted onto the mounting hole 433 on the rotating frame 43, and the other end is fitted onto the limiting hole 441 on the limiting frame 44.

[0035] When welding a workpiece using the welding torch 46, the drive motor 21 drives the drive shaft 22 to rotate synchronously according to the welding position and angle, thereby adjusting the welding angle of the welding torch 46. The telescopic connecting rod 32 slides relative to the telescopic sleeve 31 to adjust the vertical welding position, and the sliding plate 35 slides relative to the sliding bed 36 to adjust the horizontal welding position. In addition to adjusting the welding angle via the drive motor 21, the relative position of the fine-tuning groove 421 and the locking hole 432 can be adjusted according to the changes in the position and angle of different welding parts on the workpiece. This allows the rotating part 42 and the rotating frame 43 to rotate, further adjusting the angle of the welding torch 46, expanding its processing range while ensuring welding quality. Finally, the fastening bolt is inserted through the fine-tuning groove 421 into the locking hole 432 for tightening, thus fixing the angle between the rotating part 42 and the rotating frame 43, allowing welding to be performed using the welding torch 46.

[0036] The welding angle is adjusted by the drive motor 21, the vertical welding position is adjusted by the telescopic sleeve 31 and the telescopic connecting rod 32, the horizontal welding position is adjusted by the slide plate 35 and the sliding bed 36, and the welding angle is further fine-tuned by the rotation between the rotating part 42 and the rotating frame 43. This allows the welding torch 46 to adjust its angle and welding height according to the changes in the position and angle of different welding parts on the workpiece, thereby expanding the processing range of the welding torch 46 while ensuring welding quality.
