Specific embodiments

[0036] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0037] The present utility model provides a Figures 1 - 5 shown pipe welding and rotating device, including a workbench 1, and a rotating frame 2 is rotatably arranged at the top of the workbench 1;

[0038] Further, a rotating mechanism 3 is provided at the top of the workbench 1. The rotating mechanism 3 includes: a rotating table 31, a fixing frame 32, a rotating component 33, and a positioning component 34. The rotating table 31 is rotatably arranged at the top of the workbench 1 through a rotating frame 2; a plurality of fixing frames 32 are fixedly connected to the top of the rotating table 31; the rotating component 33 is arranged inside the fixing frame 32 and is used to drive the pipeline to rotate; the positioning component 34 is arranged inside the rotating table 31 and is used to fix the rotating table 31 at multiple points. By arranging the rotating component 33 on the rotating table 31, after welding the pipeline, the next group of pipelines to be welded can be rotated to the welding position through the rotating table 31, while the welded ones are rotated to the cooling area. After cooling, the pipelines to be welded are reinstalled, so that the pipeline can still be welded when it is cooling, improving the welding efficiency of the welding device and facilitating use.

[0039] Specifically, the rotating component 33 includes: a rotating pipe 331, a pressing plate 332, a rotating plate 333, a driving rod 334, and a rotating rod 335. The rotating pipe 331 is rotatably arranged inside the fixing frame 32 through a bearing; a plurality of pressing plates 332 are all located inside the rotating pipe 331. The cross-section of the pressing plate 332 is arc-shaped, and an anti-slip texture rubber pad can be additionally arranged on its inner wall, so that while protecting the pipeline, the clamping effect can be better; the rotating plate 333 is fixedly inserted and connected with the rotating pipe 331; both ends of the driving rod 334 are rotatably inserted and connected with the inner wall of the rotating plate 333; one ends of a plurality of rotating rods 335 are respectively fixedly connected with a plurality of pressing plates 332, and the other ends of a plurality of rotating rods 335 are all threadedly inserted and connected with the driving rod 334. The cross-section of the rotating rod 335 is L-shaped, and by rotating the driving rod 334 in the positive and negative directions, the driving rod 334 can drive a plurality of pressing plates 332 to approach or separate from each other, so as to clamp pipelines of different specifications. By rotating the driving rod 334, a plurality of rotating rods 335 can be driven to approach each other, so that a plurality of arc-shaped pressing plates 332 can clamp and fix the pipeline placed inside the rotating pipe 331, so that the two pipelines to be welded can be kept on the same horizontal line, thus ensuring the welding effect.

[0040] Further, the rotating assembly 33 further includes: a motor 336, a transmission rod 337, a small gear 338, and a large gear 339. The motor 336 is fixedly installed inside the fixing frame 32, and the motor 336 is electrically connected to an external power source through an externally connected switch. The transmission rod 337 is rotatably arranged between multiple fixing frames 32, and the output end of the motor 336 is drivingly connected to the transmission rod 337. Multiple small gears 338 are fixedly connected to the transmission rod 337 respectively. Multiple large gears 339 are respectively fixedly sleeved outside multiple rotating tubes 331, and the large gear 339 is meshed with the small gear 338. By driving the motor 336, multiple small gears 338 on the transmission rod 337 can be rotated, so that multiple large gears 339 can be slowly rotated in the same direction, and then the pipes clamped and fixed inside the rotating tube 331 can be driven to rotate, facilitating the welding operation.

[0041] Specifically, the positioning assembly 34 includes: a positioning rod 341, a sliding plate 342, and a compression spring 343. A plurality of positioning holes are symmetrically formed at the top end of the workbench 1. One end of the positioning rod 341 is slidably inserted through the rotating table 31, and the other end of the positioning rod 341 is slidably inserted through the inner cavity of the positioning hole. A chute is formed inside the rotating table 31. The sliding plate 342 is located inside the chute, and the positioning rod 341 is fixedly inserted through the sliding plate 342. The compression spring 343 is sleeved outside the positioning rod 341. One end of the compression spring 343 is fixedly connected to the sliding plate 342, and the other end of the compression spring 343 is fixedly connected to the top end of the inner wall of the chute. The compression spring 343 is always in a compressed state, so that a stable elastic force can be provided to the positioning rod 341 through the sliding plate 342, enabling the positioning rod 341 to closely adhere to the surface of the workbench 1. Thus, after the positioning rod 341 coincides with the positioning hole, it can be snapped into the positioning hole under the elastic force, thereby positioning the rotating table 31.

[0042] Further, protective cases 4 are fixedly connected to opposite sides of the fixing frame 32 respectively. The rotating tube 331 is rotatably inserted through the protective case 4. The protective case 4 plays a role in protecting the small gear 338 and the large gear 339, preventing foreign objects from getting stuck at the connection position.
