[0015] Embodiment 1

[0016] As Figure 1 and Figure 2 shown, a welding rotating device proposed in this embodiment includes a fixing bracket 1, a rotating shaft 2, a welding tooling 3, a servo motor 7 and a control cabinet 8.

[0017] The servo motor 7 is arranged on the fixing bracket 1, and the output end of the servo motor 7 is connected to the rotating shaft 2. The control cabinet 8 is arranged on the fixing bracket 1, and the control cabinet 8 is connected to the servo motor 7 for control.

[0018] The rotating shaft 2 is rotatably arranged on the fixing bracket 1. A bearing is installed on the fixing bracket 1, and a mounting cylinder 5 is sleeved on the bearing. The mounting cylinder 5 is located on the outer peripheral side of the rotating shaft 2, and a plurality of pressing bolts b 6 that abut against the rotating shaft 2 are threadedly connected to the mounting cylinder 5. When the servo motor 7 drives the rotating shaft 2 to rotate, the rotating shaft 2 will drive the mounting cylinder 5 to rotate through the pressing bolts b 6. The mounting cylinder 5 shields and protects the inner rotating shaft 2, and can improve the rotation stability and supporting capacity of the rotating shaft 2.

[0019] The welding tooling 3 is detachably arranged on the top of the rotating shaft 2. The welding tooling 3 includes a magnetic block 31 and a connecting cylinder 32. The magnetic block 31 is threadedly connected with a pressing bolt a 4 that abuts against the rotating shaft 2, so as to facilitate the disassembly and assembly of the magnetic block 31. The top surface of the magnetic block 31 is flat, which is convenient for flatly placing and adsorbing the workpiece to be welded. The magnetic block 31 has a placing groove 311 at the top. The rotating shaft 2 passes through the placing groove 311, and enough space for accommodating the workpiece is left between the rotating shaft 2 and the groove wall of the placing groove 311. The connecting cylinder 32 is connected to the bottom of the magnetic block 31, and the connecting cylinder 32 is sleeved on the rotating shaft 2, and can also play a certain protective role for the inner rotating shaft 2.

[0020] This embodiment can rotate the workpiece to facilitate welding at a fixed position. A cylindrical workpiece is coaxially sleeved on the top of the rotating shaft 2 and can be tightly sleeved. After sleeving, it is located inside the placement groove 311. Another workpiece with an arc-shaped or circular edge is made of ferromagnetic material and can be placed on the top surface of the magnetic block 31 and adsorbed by the magnetic block 31. This workpiece fits against the outer peripheral surface of the cylindrical workpiece, and the welding area is in an arc-shaped or circular trend around the rotating shaft 2. The welding torch is directed towards the welding area from above, and the position of the welding torch remains unchanged. The servo motor 7 is started through the control cabinet 8. The servo motor 7 drives the rotating shaft 2 to rotate, and the rotation speed should match the welding speed. The rotating shaft 2 drives the cylindrical workpiece to rotate, and the rotating shaft 2 drives another workpiece to rotate through the welding fixture 3. The two workpieces rotate synchronously, and the welding torch welds the two rotating workpieces along an arc or circular trend at a fixed position, with high welding quality and no problems such as missed welding, false welding, or over-welding. After welding, the servo motor 7 is stopped through the control cabinet 8.

[0021] Embodiment 2

[0022] This embodiment provides a welding rotation device. Compared with Embodiment 1, in this embodiment, the welding fixture 3 includes a mounting plate and a plurality of quick-clamping structures arranged on the mounting plate. The mounting plate is detachably connected to the top of the rotating shaft 2. The quick-clamping structures use quick clamps in the prior art. When welding workpieces with larger sizes are required, the magnetic block 31 and the connecting cylinder 32 in Embodiment 1 are removed, the mounting plate and the quick-clamping structures in this embodiment are installed, and the workpieces are clamped in a form distributed around the central axis of the rotating shaft 2 according to the welding trend. When the rotating shaft 2 rotates, the welding torch at a fixed position can weld the rotating workpieces along an arc or circular trend, with high welding quality.

[0023] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
