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 of 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.

[0023] Refer to Figure 1 - Figure 4, an embodiment provided by the present utility model: a welding device for processing sanitary metal pipes, including a workbench 1 and a second vertical plate 19. A fixed block 2 is fixedly connected to the upper surface of the workbench 1, a first vertical plate 3 is fixedly connected to the upper surface of the fixed block 2, a first rotating shaft 8 is fixedly connected inside the first vertical plate 3, a pipe clamping cylinder 4 is rotatably connected to the inner wall of the first rotating shaft 8, one end of a spring 5 is fixedly connected to the inner wall of the pipe clamping cylinder 4, the other end of the spring 5 is fixedly connected to a clamping block 6, a large gear 7 is fixedly connected to the outer wall of the pipe clamping cylinder 4, the large gear 7 is meshed with a small gear 10, a U-shaped plate 12 is fixedly connected to one side of the outer wall of the first vertical plate 3, a motor 11 is fixedly connected to one side of the outer wall of the U-shaped plate 12, the output end of the motor 11 is fixedly connected to one side of the outer wall of the small gear 10, a polygonal rod 13 is fixedly connected to one side of the outer wall of the small gear 10, a second rotating shaft 9 is fixedly connected inside the first vertical plate 3, the inner wall of the second rotating shaft 9 is rotatably connected to the outer wall of the polygonal rod 13, a positioning cylinder 14 is rotatably connected to the inner wall of the second rotating shaft 9, the inner wall of the positioning cylinder 14 is slidably connected to the outer wall of the polygonal rod 13, a fixing plate 18 is fixedly connected to the lower surface of the second vertical plate 19, a cylinder 17 is fixedly connected to the lower surface of the workbench 1, the output end of the cylinder 17 is fixedly connected to one side of the outer wall of the fixing plate 18, a guiding component is arranged on the upper surface of the workbench 1, and the guiding component can make the first vertical plate 3 slide along a straight line to keep the moving track of the metal pipe in a straight line. The guiding component includes a slide rail 16, the lower surface of the slide rail 16 is fixedly connected to the upper surface of the workbench 1, a slider 15 is slidably connected to the outer wall of the slide rail 16, and the upper surface of the slider 15 is fixedly connected to the lower surface of the second vertical plate 19.

[0024] Specifically, first, the metal pipe to be welded needs to be inserted into the pipe clamping cylinder 4 on the first vertical plate 3. Through the clamping block 6 and the spring 5 arranged in the pipe clamping cylinder 4, the fixing of metal pipes of different sizes is realized under the elastic action of the spring 5. Then, under the telescopic action of the cylinder 17 and the sliding action of the slide rail 16, the second vertical plate 19 is driven to move leftward, and then the pipe clamping cylinder 4 on the second vertical plate 19 is driven to approach the pipe clamping cylinder 4 on the first vertical plate 3, realizing the anastomosis docking of the two metal pipes. After that, the motor 11 is started to drive the small gear 10 to rotate. Through the insertion connection of the polygonal rod 13 and the positioning cylinder 14, another small gear 10 is driven to rotate at the same time. Then, through the meshing connection of the small gear 10 and the large gear 7, the large gear 7 is also driven to rotate. Then, through the fixed connection of the pipe clamping cylinder 4 and the large gear 7, the rotation of the two pipe clamping cylinders 4 is realized, thus completing the synchronous rotation of the two docked metal pipes. And the operator only needs to align the welding torch 25 with the welding place, which not only reduces the labor intensity but also improves the welding efficiency.

[0025] Refer to Figure 1 - Figure 4, a support column 20 is fixedly connected to the upper surface of the workbench 1, a fixed platform 22 is fixedly connected to the upper surface of the support column 20, a connecting column 21 is fixedly connected to the lower surface of the fixed platform 22, the lower surface of the connecting column 21 is fixedly connected to the upper surface of the workbench 1, a slide bar 23 is fixedly connected to one side of the outer wall of the fixed platform 22, a sliding block 30 is slidably connected to the outer wall of the slide bar 23, a handle 29 is fixedly connected to the upper surface of the sliding block 30, a connecting shaft 24 is fixedly connected to the lower surface of the sliding block 30, a welding torch 25 is rotatably connected inside the connecting shaft 24, a threaded fixing sleeve 27 is fixedly connected inside the welding torch 25, a gun head 26 is fixedly connected to the inner wall of the threaded fixing sleeve 27, and a nut 28 is threadedly connected to the outer wall of the threaded fixing sleeve 27.

[0026] Specifically, after the docking of two butt-jointed metal pipes is completed, by installing the sliding block 30 on the slide bar 23 and fixing the welding torch 25 on the sliding block 30, due to the sliding action of the slide bar 23, at this time, the operator does not need to hold the welding torch 25 for a long time. Just by pushing the handle 29, the welding torch 25 can be slid left and right to adjust to the best position for welding the metal pipe, greatly reducing the contact time between the operator and the welding torch 25 and improving safety. When the welding torch 25 is used for a long time, the gun head 26 will be damaged. By the combined use of the threaded fixing sleeve 27 and the nut 28, the nut 28 is turned to replace a new gun head 26 and then the welding work is carried out, realizing the convenience for the operator to replace the gun head 26.

[0027] Working principle: When in use, the operator first guides the metal pipe to be welded into the pipe clamping cylinder 4. There are clamping blocks 6 in the pipe clamping cylinder 4, and there is a spring 5 on each clamping block 6. When metal pipes of different sizes enter the pipe clamping cylinder 4, they will be fixed by the clamping blocks 6 under the telescopic action of the springs 5. Similarly, another metal pipe to be welded is inserted into the pipe clamping cylinder 4 and a part of it extends beyond the pipe clamping cylinder 4. Then the air cylinder 17 is started. Under the telescopic action of the air cylinder 17 and the sliding action of the slide rail 16, the pipe clamping cylinder 4 on the second vertical plate 19 is driven to approach the pipe clamping cylinder 4 on the first vertical plate 3, realizing the stable docking of the two metal pipes. At the same time, the multi-angle rod 13 will be inserted into the positioning cylinder 14 along with the movement of the second vertical plate 19, and at this time, the docking of the two metal pipes is completed.

[0028] After the docking is completed, the motor 11 is started to drive the small gear 10 to rotate. At the same time, due to the fit between the multi-angle rod 13 and the notch of the positioning cylinder 14, when the small gear 10 drives the multi-angle rod 13 to rotate, it also drives another small gear 10 to rotate. At this time, the small gear 10 will also drive the large gear 7 to rotate. Because the pipe clamping cylinder 4 and the large gear 7 are fixedly connected, the two pipe clamping cylinders 4 will be driven to rotate, realizing the rotational docking of the two metal pipes.

[0029] After the rotational docking of the two metal pipes is completed, the welding torch 25 can be adjusted to a suitable position and then the welding torch 25 is started. At this time, there is no need to move the welding torch 25. Just wait until the metal pipe rotates one full circle to complete the welding of the metal pipe, and then take out the welded metal pipe. When the welding torch 25 is used for a long time, the tip 26 of the torch will be damaged and the tip 26 needs to be replaced. At this time, turn the nut 28 to remove the tip 26, then replace it with a new tip 26 and carry out the welding work again.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
