Example

[0021] As attached Figures 1 to 3 The steel pipe ellipticity online correction and stable transmission device shown includes a base plate 1. A limiting groove 7 is formed on the upper part of the base plate 1. There are two limiting grooves 7. A motor 8 is fixedly installed inside the base plate 1. The output end of the motor 8 is connected to a threaded rod 9. An external threaded sleeve 10 is threaded on the outer side of the threaded rod 9. A limiting rod 11 is fixedly installed inside the limiting groove 7 on the other side. A sliding sleeve 12 is sleeved on the outer side of the limiting rod 11. A bearing frame 13 is fixedly installed on the top of the external threaded sleeve 10 and the sliding sleeve 12.

[0022] In the structural design of the base plate 1, the two limiting grooves 7 not only serve as limiting devices but also enhance the stability of the overall structure. The motor 8, as a power source, is installed inside the limiting groove 7, and its efficient operation provides the necessary driving force for the entire device. The threaded rod 9 is tightly connected to the output end of the motor 8. Through the rotation of the motor 8, the threaded rod 9 can drive the external threaded sleeve 10 to move linearly. At the same time, the limiting rod 11 is firmly installed in the limiting groove 7 on the other side, which ensures the straightness and stability of the sliding sleeve 12 during movement. The sliding sleeve 12 slides freely along the limiting rod 11, and its coordinated action with the external threaded sleeve 10 enables the bearing frame 13 to achieve stable and precise displacement in the horizontal direction.

[0023] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 3 As shown below, see details:

[0024] In a preferred embodiment, a fixing plate 2 is fixedly installed above the base plate 1, and a first telescopic mechanism 3 is fixedly installed on the opposite side of the fixing plate 2. A first clamping plate 4 is provided at the end of the first telescopic mechanism 3 away from the fixing plate 2. A first fixing rod 5 is fixedly installed inside the fixing plate 2, and a second clamping plate 6 is fixedly installed at the end of the first fixing rod 5 away from the first clamping plate 4. Furthermore, by steadily installing the fixing plate 2 above the base plate 1, it plays a key role as a supporting structure. The first telescopic mechanism 3 is fixed on the opposite side of the fixing plate 2, and its telescopic end is tightly connected to the first clamping plate 4. Through telescopic movement, it can flexibly clamp items of different sizes. At the same time, the first fixing rod 5 penetrates the fixing plate 2, and one end of it is firmly connected to the second clamping plate 6, forming a clamping structure with the first clamping plate 4, which further enhances the stability and reliability of clamping.

[0025] In a preferred embodiment, the external threaded sleeve 10 and the sliding sleeve frame 12 are on the same horizontal plane; furthermore, by carefully adjusting the external threaded sleeve 10 and the sliding sleeve frame 12 to be on exactly the same horizontal plane, not only is the synchronicity of movement guaranteed, but also the stability of the support frame 13 during movement is ensured.

[0026] In a preferred embodiment, a second telescopic mechanism 14 is fixedly installed on the inner wall of the support frame 13, and a third clamping plate 15 is fixedly installed at the output end of the second telescopic mechanism 14. A second fixing rod 16 is fixedly installed on the inner wall of the other side of the sliding sleeve frame 12, and a fourth clamping plate 17 is fixedly installed at one end of the second fixing rod 16. Furthermore, the second telescopic mechanism 14 is securely installed on the inner wall of the support frame 13, and its output end is connected to the third clamping plate 15. The clamping force and range can be flexibly adjusted through telescopic movement. At the same time, the second fixing rod 16 is firmly fixed on the inner wall of the other side of the sliding sleeve frame 12, and a fourth clamping plate 17 is installed at one end of it. Together with the third clamping plate 15, a more stable and reliable clamping system is formed, which is suitable for various clamping needs.

[0027] In a preferred embodiment, the first clamping plate 4 and the second clamping plate 6 overlap to form a circle, and a dust collection box is placed at the bottom of the first clamping plate 4 and the second clamping plate 6. Furthermore, when the first clamping plate 4 and the second clamping plate 6 are tightly overlapped, they together form a circular clamping space, which is particularly suitable for clamping round items. In addition, in order to facilitate the collection and disposal of any debris or dust that may be generated, a dust collection box is placed at the bottom of the first clamping plate 4 and the second clamping plate 6 to ensure a clean and efficient working environment.

[0028] In a preferred embodiment, a support plate 18 is fixedly installed above the base plate 1, and a tray 19 is fixedly installed on the top of the support plate 18. The tray 19 is located to the right of the third clamping plate 15 and the fourth clamping plate 17. Furthermore, on the stable foundation of the base plate 1, the support plate 18 is firmly installed on top, adding extra stability to the overall structure. The tray 19 is installed on the top of the support plate 18, and its position is carefully set to the right of the third clamping plate 15 and the fourth clamping plate 17, which not only facilitates operation but also effectively utilizes space and improves work efficiency.

[0029] The working process of this utility model is as follows: During use, the equipment is first fixed at the designated location. Then, the pipe is placed between the first clamping plate 4 and the second clamping plate 6, and between the third clamping plate 15 and the fourth clamping plate 17. The second telescopic mechanism 14 is activated to clamp the pipe, making it tightly adhere to the inner walls of the third and fourth clamping plates. After fixing, the first telescopic mechanism 3 is activated simultaneously, causing the first clamping plate 4 to move towards the pipe, but not tightly adhere to the pipe. The motor 8 is started, and the motor 8 drives the threaded rod 9 to rotate, thereby driving the external threaded sleeve 10 and its connected support frame 13 to move, so as to achieve the stretching and correction of the pipe. This equipment is powerful and can adapt to various pipe sizes. By flexibly adjusting the clamping mechanism, it can effectively achieve precise clamping and correction of different pipes, ensuring accurate pipe installation, high correction accuracy, and highly intuitive correction results, making it easy to operate.
