Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, specifically an internal support welding auxiliary device that can adapt to the size of the cylinder. Background Technology

[0002] In pipeline welding operations, ensuring stable support and precise positioning of the pipeline is crucial. Traditional welding auxiliary support devices often have fixed structures, making it difficult to flexibly adapt to cylinders of different diameters.

[0003] When faced with diverse pipe size requirements, operators have to frequently change support equipment or make complex manual adjustments. This not only consumes a lot of time and manpower, but also easily leads to inconsistent welding quality due to unstable support, failing to meet the requirements of efficient and high-quality modern welding processes.

[0004] To address this issue, the present invention provides an internally supported welding auxiliary device that can adapt to the size of the cylinder, thereby solving the aforementioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an internally supported welding auxiliary device that can adapt to the size of the cylinder, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an internally supported welding auxiliary device adaptable to the size of a cylindrical body, comprising a frame, a support assembly on the side of the frame, the support assembly including a slide rail, the slide rail being fixedly installed on the side of the frame, a slider being slidably connected to the outside of the slide rail, an internal support plate being fixedly installed on the outside of the slider, an internal support pad being fixedly installed on the outside of the internal support plate, the outer edge of the internal support pad being arc-shaped, and the internal support plate and the internal support pad being respectively arranged in the four directions of up, down, left, and right on the side of the frame.

[0007] Preferably, a first cylinder is fixedly installed on the left side of the frame, the output end of the first cylinder moves through the interior of the frame, an inner support core is fixedly installed on the output end of the first cylinder, and a connecting rod is hinged between the inner support core and the corresponding inner support plate.

[0008] Preferably, a horizontal plate is fixedly installed on the side of the frame, a second cylinder is fixedly installed on the top of the horizontal plate, and an external clamping plate is fixedly installed on the output end of the second cylinder.

[0009] Preferably, the two external clamping plates are located on the outer sides of the inner support plates on the left and right sides, respectively, and the inner ends of the external clamping plates are arc-shaped.

[0010] Preferably, a support rod is fixedly installed on the side of the frame, a limit plate is fixedly installed between the outer ends of the support rod, a limit rod is fixedly installed on the outer end of the inner support core, and the limit rod is inserted into the inside of the limit plate.

[0011] Preferably, a top plate is fixedly installed on the outer end of the limiting rod, and the limiting plate is located between the outer end of the inner support core and the top plate.

[0012] Beneficial effects

[0013] This invention provides an internally supported welding auxiliary device that can adapt to the size of the cylinder. Compared with the prior art, it has the following advantages:

[0014] 1. This adaptive internal support welding auxiliary device, driven by a first cylinder, allows multiple internal support plates to expand outward or contract inward simultaneously via a connecting rod structure. The internal support plates slide smoothly on a slide rail with the aid of sliders, precisely fitting the inner wall of pipes of different diameters. Regardless of changes in pipe size, it can quickly complete the support adaptation, improving the device's versatility for different cylinders, reducing time losses caused by changing support equipment, and improving welding efficiency.

[0015] 2. This adaptive internal support welding auxiliary device, which can adapt to the cylinder size, supports the pipe from the inside through the internal support plate. Then, the external second cylinder drives the external clamping plate to move inward, further clamping and fixing the pipe from the outside. This internal and external coordinated fixing method effectively disperses the stress on the pipe, avoids pipe shaking or displacement that may be caused by a single support method, provides a stable working foundation for the welding process, ensures welding quality, and reduces the probability of welding defects.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 4 This application provides an internally supported welding auxiliary device that can adapt to the size of a cylindrical body. It includes a frame 1, a support component 2 on the side of the frame 1, and a slide rail 24. The slide rail 24 is fixedly installed on the side of the frame 1. A slider 23 is slidably connected to the outside of the slide rail 24. An internal support plate 21 is fixedly installed on the outside of the slider 23. An internal support pad 22 is fixedly installed on the outside of the internal support plate 21. The outer edge of the internal support pad 22 is arc-shaped. The internal support plate 21 and the internal support pad 22 are respectively arranged in the four directions of up, down, left, and right on the side of the frame 1.

[0025] A first cylinder 25 is fixedly installed on the left side of the frame 1. The output end of the first cylinder 25 extends through the interior of the frame 1. An inner support core 26 is fixedly installed at the output end of the first cylinder 25. A connecting rod 27 is hinged between the inner support core 26 and the corresponding inner support plate 21. A horizontal plate 3 is fixedly installed on the side of the frame 1. A second cylinder 4 is fixedly installed on the top of the horizontal plate 3. An external clamping plate 5 is fixedly installed at the output end of the second cylinder 4. The two external clamping plates 5 are located on the outer sides of the inner support plates 21 on the left and right sides, respectively. The inner ends of the external clamping plates 5 are arc-shaped. A support rod 8 is fixedly installed on the side of the frame 1. A limit plate 7 is fixedly installed between the outer ends of the support rod 8. A limit rod 6 is fixedly installed on the outer end of the inner support core 26. The limit rod 6 is inserted into the interior of the limit plate 7. A top plate is fixedly installed on the outer end of the limit rod 6. The limit plate 7 is located between the outer end of the inner support core 26 and the top plate.

[0026] In this embodiment, when supporting the pipe during pipe welding, the pipe is fitted between multiple inner support plates 21 on the outer side. Only by activating the first cylinder 25 to move the inner support core 26 outward, thereby pushing the connecting rod 27 outward, and further pushing the inner support plates 21 outward, can the inner support plates 21 move outward. When the inner support plates 21 move outward, they slide on the slide rail 24 via the slider 23, thus ensuring that the inner support plates 21 can move vertically along the slide rail 24. By having multiple inner support plates 21 move outward synchronously and the inner support pads 22 are attached to the inner wall of the pipe, the pipe can be supported and fixed. This method can be used for pipes of different diameters. All pipes can be supported; and during support, the inner support core 26 moves back and forth inside the limiting plate 7 via the limiting rod 6, and the movement of the limiting plate 7 can be limited on the support rod 8 by the limiting of the outer top. By limiting the inner support core 26, the inner support plate 21 can be moved within the range of movement, preventing the inner support plate 21 from moving too far. After the pipe is supported, the outer second cylinder 4 is activated to drive the outer clamping plate 5 to move inward. The outer clamping plate 5 fits against the outer side of the pipe from the outside, which can further clamp and fix the pipe from the outside, thereby improving the stability of clamping.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] Working principle: When supporting the pipe during pipe welding, the pipe is fitted between multiple inner support plates 21 on the outside. Only by activating the first cylinder 25, which moves the inner support core 26 outward, can the connecting rod 27 be moved outward, thereby pushing the inner support plates 21 outward. As the inner support plates 21 move outward, they slide on the slide rail 24 via the slider 23, ensuring that the inner support plates 21 can move vertically along the slide rail 24. By having multiple inner support plates 21 move outward synchronously, and the inner support pads 22 are attached to the inner wall of the pipe, the pipe can be supported and fixed. This method can be used for pipes of different diameters. All pipes can be supported; and during support, the inner support core 26 moves back and forth inside the limiting plate 7 via the limiting rod 6, and the movement of the limiting plate 7 can be limited on the support rod 8 by the limiting of the outer top. By limiting the inner support core 26, the inner support plate 21 can be moved within the range of movement, preventing the inner support plate 21 from moving too far. After the pipe is supported, the outer second cylinder 4 is activated to drive the outer clamping plate 5 to move inward. The outer clamping plate 5 fits against the outer side of the pipe from the outside, which can further clamp and fix the pipe from the outside, thereby improving the stability of clamping.
