Also, appropriately adjust the lifting table 29 so that the two cylinders to be welded are approximately on the same plane.

[0024] Embodiment 2

[0025] Please refer to Figure 3 , on the basis of Embodiment 1, the telescopic component 11 includes a sliding block 20 and a telescopic rod 16. The sliding block 20 is slidably connected to the third slideway 23. The distance that the sliding block 20 slides is exactly the same as the distance that the sliding rod 22 slides in the fourth slideway 30. In this way, in order to prevent the sliding block 20 from sliding out of the third slideway 23 and also ensure that the telescopic rod 16 will not easily slide out of the track. An internal chute is provided on the lower surface of the sliding block 20. The bottom wall of the internal chute is the bottom wall of the third slideway 23. The telescopic rod 16 extends into the internal chute and is slidably connected thereto. The telescopic rod 16 is also slidably connected to the bottom wall of the third slideway 23. One end of the internal chute 21 is fixedly connected to a fixing rod 18. One end of the fixing rod 18 extends into the telescopic rod 16 and is slidably connected thereto. The other end of the fixing rod 18 extends into one end of the telescopic rod 16 and is slidably connected thereto without separation. A first spring 19 is fixedly connected in the internal chute 21. One end of the first spring 19 is fixedly connected to one end of the internal chute 21. The other end of the first spring 19 is fixedly connected to one end of the telescopic rod 16. Fourth slideways 30 are provided on both side walls of the third slideway 23. The fourth slideways 30 are provided in the third slideway 23 and are shorter than the third slideway 23. Slide rods 22 are fixedly connected to both sides of the sliding block 20. The slide rods 22 are slidably connected to the fourth slideways 30.

[0026] A number of first threaded holes 17 are provided on the telescopic rod 16. The existence of multiple first threaded holes 17 enables the telescopic rod 16 to be fixed and used. A threaded nail 24 is provided at the bottom of the third slideway 23. The threaded nail 24 penetrates the bottom wall of the third slideway 23 and extends into one of the first threaded holes 17 to be threadedly connected thereto. In this way, when fixation is required, the telescopic rod 16 can be fixed using the threaded nail 24. When adjustment is required, loosening the thread allows the length of the telescopic rod 16 to be adjusted, and the telescopic rod 16 will move together with the first roller.

[0027] A second slideway 15 is provided between the two first slideways 14. The second slideway 15 is relatively wide. An intermediate block is provided at the middle position of the second slideway 15. The middle part of the moving platform 9 is embedded with a second electric push rod 27. The output end of the second electric push rod 27 is fixedly connected to the lower surface of the lifting platform 29. Therefore, the telescopic movement of the output end of the second electric push rod 27 can drive the lifting of the lifting platform 29. The upper surfaces at both ends of the moving platform 9 are both slidably connected with lifting columns 28. The lifting columns 28 are embedded in the moving platform 9 and are slidably connected therewith. When the second electric push rod 27 drives the lifting platform 29 to lift or lower, the lifting columns 28 will also lift or lower. A connecting block 25 is fixedly connected to the bottom of the moving platform 9. The connecting block 25 extends into the second slideway 15. The connecting block 25 does not contact the bottom of the second slideway 15. A second threaded hole 26 is provided in the connecting block 25. Threads are provided in the second threaded hole 26. A threaded rod 13 is threadedly connected in the second threaded hole 26. One end of the threaded rod 13 is rotatably connected to the intermediate block, and the other end of the threaded rod 13 is rotatably connected to the side wall of the second slideway 15. Motors 12 are fixedly installed on both sides of the working plate 8. The output end of the motor 12 is fixedly connected to the threaded rod 13.

[0028] During the use process, after selecting a suitable position on the telescopic rod 16, it can be fixed with the threaded nail 24, and then the cylinder is placed. However, when it is necessary to move the two clamped cylinders, the two motors 12 can be started simultaneously. When the motors 12 are started, the two threaded rods 13 both rotate slowly, and the two cylinders move towards the middle simultaneously. When they are about to fit, the motors 12 are turned off and the second electric push rod 27 is started. The purpose is to make the sides of the two cylinders of the same size fit, so as to prepare for the subsequent welding.

[0029] Embodiment 3

[0030] Please refer to Figure 4 , on the basis of Embodiment 2, a moving plate 5 is slidably connected between the two brackets 3. The moving plate 5 can move freely. A first electric push rod 6 is fixedly installed on the upper surface of the above-mentioned moving plate 5. The first electric push rod 6 can move together with the moving plate 5. A pressing mechanism 4 is provided on the lower surface of the output end of the first electric push rod 6. A small motor 12 is provided in the pressing mechanism 4 and can drive some rollers to rotate. After being pressed in this way, when the small motor 12 is started, it can drive the two cylinders to rotate slowly. A protective plate 7 is provided on one side of each bracket 3. The protective plate 7 is used to prevent the sparks and debris generated during welding from flying out of the equipment and polluting the human body and the environment.

[0031] In actual use, first adjust the telescopic rod 16. By using the threaded nail 24, adjust the telescopic rod 16 to a suitable position so that the two first rollers 10 are in a suitable position to support the cylinder to be placed and allow the cylinder to rotate freely on the device. Then start the first electric push rod 6 so that the pressing mechanism 4 presses on the cylinder and clamps it, thus fixing the cylinder. After fixing, start the motor 12 to make the two fixed cylinders move closer to each other. When the two cylinders are about to touch, stop the motor 12 first and start the second electric push rod 27. The second electric push rod 27 will drive the working plate 8 to move up and down until the sides of the two cylinders are completely aligned. Finally, start the motor 12 again to align and almost fit the sides of the two cylinders, and then perform welding. Since the protective plate 7 plays a very good protective role, it greatly reduces the splashing of metal particles during the welding process. During the welding process, the presence of the small motor 12 allows the two cylinders to be welded to rotate synchronously.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
