During manufacturing and processing, a cylinder may deform due to heat treatment, welding or other processes. Internal supports can ensure that the cylinder maintains its round shape during these processes and reduce deformation. Therefore, hydraulic cylinder support devices are used for welding cylinders.

[0003] The hydraulic support device for cylindrical welding is a device used to support and correct the shape of a cylindrical tube during the welding process. Powered by a hydraulic system, the support device can apply pressure evenly. In existing cylindrical welding technology, the internal support of the cylinder is not well handled, which can easily lead to deformation or displacement of the cylinder during the welding process, affecting the welding accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a hydraulic cylinder support device for cylinder welding, which aims to improve the problem that without proper internal support of the cylinder, the cylinder is prone to deformation or displacement during welding, thus affecting welding accuracy.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a cylindrical welding hydraulic support device, including a rotating cylinder 1. A cylinder 2 is fixedly connected inside the rotating cylinder 1. A fixing ring 3 is fixedly connected to the outer wall of the cylinder 2. A push plate 4 is fixedly connected to the output end of the cylinder 2. A first rotating shaft 5 is rotatably connected inside the push plate 4. A first rotating block 6 is fixedly connected to the outer wall of the first rotating shaft 5. A second rotating shaft 7 is rotatably connected inside the first rotating block 6. An inner support plate 8 is fixedly connected to the outer wall of the second rotating shaft 7. A first rotating rod 9 is fixedly connected inside the inner support plate 8. A second rotating block 10 is rotatably connected to the outer wall of the first rotating rod 9. A second rotating rod 11 is fixedly connected to the inner wall of the second rotating block 10. The outer wall of the second rotating rod 11 is rotatably connected inside the fixing ring 3. A rotating assembly is provided on the outer wall of the rotating cylinder 1.

[0025] Specifically, the rotating cylinder 1 fixes the cylinder 2. Activating the cylinder 2 pushes the pusher 4 to slide. The first rotating shaft 5 connects the first rotating block 6 and the pusher 4, allowing the first rotating block 6 to rotate synchronously via the sliding of the first rotating shaft 5. The second rotating shaft 7 connects the first rotating block 6 and the inner support plate 8, allowing the inner support plate 8 to slide closer to the inner wall of the cylindrical body 14 via rotation of the second rotating shaft 7. Four inner support plates 8 are designed to provide even support to the cylindrical body 14. The first rotating rod 9 connects the inner support plate 8 and the second rotating block 10. The sliding of the inner support plate 8 can drive the second rotating block 10 to slide synchronously. The second rotating rod 11 serves to connect the second rotating block 10 and the fixing ring 3, allowing the second rotating rod 11 to rotate synchronously with the rotation of the second rotating block 10. The fixing ring 3 is fixed to the outer wall of the cylinder 2, providing stable support for the rotation of the second rotating rod 11. The joint rotation of the first rotating block 6 and the second rotating block 10 can provide stable support for the inner support plate 8, thereby providing stable support for the cylindrical body 14. Through uniform inner support force, deformation or displacement during welding can be effectively reduced.

[0026] Reference Figure 4 The outer wall of the rotating drum 1 is rotatably connected to a support plate 12, the outer wall of the support plate 12 is fixedly connected to a motor 13, the output end of the motor 13 is fixedly connected to the outer wall of the rotating drum 1, and the outer wall of the inner support plate 8 is slidably connected to a cylindrical body 14.

[0027] Specifically, the support plate 12 serves to fix the motor 13. When the motor 13 is started, the rotating drum 1 can rotate stably inside the support plate 12 through the driving action of the motor 13. The rotating drum 1 can drive the cylindrical body 14 to rotate synchronously, and weld different positions of the cylindrical body 14.

[0028] Reference Figure 4 and Figure 5 A slider 15 is fixedly connected to the lower surface of the support plate 12. An adjustment platform 16 is slidably connected inside the slider 15. Multiple slots 17 are provided inside the adjustment platform 16. A push post 18 is slidably connected inside the slider 15. A connecting piece 19 is fixedly connected to the outer wall of the push post 18. A connecting shaft 20 is fixedly connected inside the connecting piece 19. A slide plate 21 is slidably connected to the outer wall of the connecting piece 19. A slide groove 22 is provided inside the slide plate 21. The outer wall of the connecting shaft 20 is slidably connected to the inner wall of the slide groove 22. A slide post 23 is fixedly connected to the outer wall of the slide plate 21. The outer wall of the slide post 23 is slidably connected to the inside of the adjustment platform 16. A locking post 24 is fixedly connected to the outer wall of the slide post 23. The outer wall of the locking post 24 is slidably connected to the inside of the slider 15. The outer wall of the locking post 24 is slidably connected to the inner wall of the slot 17. A spring 25 is slidably connected to the outer wall of the slide post 23. One end of the spring 25 is fixedly connected to the inside of the slider 15. The other end of the spring 25 is fixedly connected to the outer wall of the locking post 24.

[0029] Specifically, the slider 15 supports and fixes the support plate 12. Moving the slider 15 facilitates the movement of the cylindrical body 14. The adjusting platform 16 limits and supports the slider 15. The multiple slots 17 inside the adjusting platform 16 allow for selection of different slots 17 to adjust the position of the slider 15 as needed. The slider 15 supports the push post 18, which fixes the connecting piece 19. Pushing the push post 18 causes the connecting piece 19 to slide synchronously within the slider 15. The connecting piece 19 fixes the connecting shaft 20, allowing it to slide. The connecting shaft 20 connects the slide plate 21 and the connecting piece 19, and is located on the inner wall of the groove 22. When the connecting shaft 20 slides, it conforms to the shape of the groove 22 and slides accordingly. During the sliding process, a pushing force is applied to the slide plate 21, causing it to slide inside the slider 15. The slide plate 21 serves to fix the slide post 23, which connects the slide plate 21 and the locking post 24. Consequently, the locking post 24 slides synchronously inside the slider 15 as the slide post 23 slides. The spring 25 is located between the slider 15 and the locking post 24 and is compressed due to the sliding of the locking post 24. During the sliding process, the locking post 24 will disengage from the locking groove 17. When the locking posts 24 on both sides slide out of the locking groove 17, the position of the slider 15 on the adjustment table 16 can be flexibly adjusted. Different locking grooves 17 can be selected according to different welding requirements. By releasing the push post 18, the spring 25 is no longer compressed and can push the locking post 24 to slide in the opposite direction through its own rebound, thus completing the limiting and fixing between the slider 15 and the adjustment table 16.

[0030] Working principle: When the device is needed, the cylindrical body 14 to be welded is placed on the outer wall of the inner support plate 8. The cylinder 2 is started to push the push plate 4 to slide. When the push plate 4 slides, it will drive the first rotating shaft 5 to slide. During the sliding process, the first rotating shaft 5 will push the first rotating block 6 to rotate. During the rotation of the first rotating block 6, it will push the inner support plate 8 to fit against the inner wall of the cylindrical body 14 through the second rotating shaft 7. At the same time, the inner support plate 8 will drive the second rotating block 10 to rotate through the first rotating rod 9. By adjusting the position of the inner support plate 8 to fit tightly against the inner wall of the cylindrical body 14, the cylindrical body 14 can be stably supported. The pressure is applied evenly through the inner support and the cylindrical body 14 is fixed, ensuring that the cylindrical body 14 maintains its round shape during the welding process. This helps to reduce welding deformation and improve welding quality. The motor 13 is started to drive the rotating drum 1 to rotate, thereby driving the cylindrical body 14 to rotate through the rotation of the rotating drum 1, and welding is performed on different positions of the cylindrical body 14.

[0031] When the position of the cylindrical body 14 needs to be adjusted, simply push the push post 18. The push post 18 will cause the connecting piece 19 and the connecting shaft 20 to slide inside the slider 15. The connecting shaft 20 is located on the inner wall of the slide groove 22. When the connecting shaft 20 slides, it will slide on the inner wall of the slide groove 22 and push the slide plate 21 to slide during the sliding process. During the sliding process, the slide plate 21 will cause the sliding post 23 and the locking post 24 to slide simultaneously, and will compress the spring 25 during the sliding process. Sliding the locking post 24 out of the inner wall of the locking slot 17 can push the slider 15 to slide on the outer wall of the adjusting platform 16. Due to the opening of multiple locking slots 17, a suitable locking slot 17 can be selected to loosen the slide. The push column 18, through the rebound of the spring 25, can push the locking column 24 in the opposite direction to engage with the inner wall of the locking groove 17, fixing the position of the slider 15 and the adjusting table 16. This ensures that the cylindrical body 14 and the welding device always maintain the optimal welding position, avoiding the limitation of the welding range due to the fixed position. This device can not only apply pressure evenly through the internal support and fix the cylindrical body 14, ensuring that the cylindrical body 14 maintains its roundness during the welding process, which helps to reduce welding deformation and improve welding quality, but also ensure that the cylindrical body 14 and the welding device always maintain the optimal welding position, avoiding the limitation of the welding range due to the fixed position.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
