Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, in particular to a fixing device for pipeline welding. Background Art

[0002] At present, welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. A large number of pipelines are used, so the number of welds between them is also very large. Therefore, it is necessary to optimize the welding of pipelines.

[0003] For example, a pipeline welding fixing device is disclosed in the Chinese utility model patent with the publication number CN213531475U. Although the above-mentioned prior art facilitates the butt-joint work before pipeline welding and solves the problem that the low butt-joint efficiency of the existing pipeline welding fixing device seriously affects the welding efficiency, when simply clamping the pipeline with two clamping plates, the pipeline will rotate with only a small force because of the small contact area with the clamping plate, even if the rotational force is small, it will cause one end of the pipeline to shift, resulting in the deviation of the welding position. Therefore, it is necessary to design a fixing device for pipeline welding that can completely fix and lock the pipeline. Summary of the Invention

[0004] To solve the technical problem that simply clamping the pipeline will cause the deviation of the welding position between pipelines, the utility model provides a fixing device for pipeline welding.

[0005] The utility model is realized by the following technical solutions: A fixing device for pipeline welding, including a welding platform, on one side of the welding platform, there are multiple fixing components for fixing and clamping the pipelines to be welded. On one side of the multiple fixing components, there is a driving component for driving adjacent fixing components to move. On one side of each fixing component, there is a limiting component for aligning and restricting the clamped pipeline. The fixing component includes a sliding block arranged on one side of the welding platform, a first clamping plate fixedly installed on one side of the sliding block, and a second clamping plate rotatably installed on one side of the first clamping plate.

[0006] Through the above technical solutions, two pipelines are fixed by the fixing components, and then the driving component is used to move the fixing components, so that the two pipelines can be tightly fitted together, and the limiting component will limit one end of the pipeline to prevent the pipeline from shifting during the welding process.

[0007] As a further improvement of the above solution, both the first clamping plate and the second clamping plate are arranged in a semi-circular ring shape.

[0008] Through the above technical solutions, the clamping plates arranged in a semi-circular ring shape can better clamp the pipeline.

[0009] As a further improvement of the above solution, sliding grooves are provided on one side of the inner walls of the first clamping plate and the second clamping plate, sliders are slidably installed inside the two sliding grooves, rubber plates are provided on one side of the inner walls of the first clamping plate and the second clamping plate, and each rubber plate is fixedly installed on one side of the adjacent slider.

[0010] Through the above technical solution, the rubber plate will rub against the pipeline and the clamping plate, preventing the pipeline from sliding after being clamped, and the slider can be used to replace the rubber plate with a thickness adapted to the current pipeline.

[0011] As a further improvement of the above solution, limit plates are fixedly installed on one side of the first clamping plate and the second clamping plate, a threaded column is provided on one side of one of the limit plates, one end of the threaded column penetrates through the adjacent limit plate and is in threaded cooperation with the other limit plate, and a rotating block is fixedly installed at the other end of the threaded column.

[0012] Through the above technical solution, when the threaded column rotates, the two limit plates will be locked, and the first clamping plate and the second clamping plate can be locked and fixed.

[0013] As a further improvement of the above solution, a sliding groove is provided on one side of the welding platform, the driving assembly includes a bidirectional threaded rod arranged inside the sliding groove and a servo motor arranged on one side of the welding platform, and one end of the bidirectional threaded rod penetrates through the welding platform and is fixedly installed at the output end of the servo motor.

[0014] Through the above technical solution, when the servo motor is started, the bidirectional threaded rod will rotate, so that the sliding block will also move.

[0015] As a further improvement of the above solution, the two sliding blocks are in threaded cooperation with the bidirectional threaded rod.

[0016] Through the above technical solution, when the bidirectional threaded rod rotates, the two sliding blocks will move together.

[0017] As a further improvement of the above solution, the limiting assembly includes a limiting plate fixedly installed on one side of the second clamping plate and provided with a limiting opening, a sliding plate slidably installed inside the limiting opening, and a limiting ring fixedly installed on one side of the sliding plate.

[0018] Through the above technical solution, the limiting ring can sleeved the end of the pipeline to be welded, so that the welding position can be prevented from being offset by external force during welding.

[0019] As a further improvement of the above solution, the inner diameter of the limiting ring is the same as the combined inner diameter of the two rubber plates.

[0020] Through the above technical solution, the limiting ring can sleeved and restrict the pipeline without leaving a large gap.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] By setting a fixing component, a driving component and a limiting component, the fixing component clamps and fixes the pipeline to be welded, the limiting component sleeves the end of the pipeline to be welded, and the driving component is used to move the two fixing components, so that the two pipelines are fitted together for welding. The movement of the fixing component is restricted, so the two pipelines will not move and deviate. Such a setting can not only clamp and fix the welded pipeline, but also make the clamped pipeline move and fit by itself, without the need for workers to manually push the two pipelines together.

Detailed Embodiments

[0029] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be combined arbitrarily to form new embodiments.

[0030] Please combine Figures 1 - 4, A fixing device for pipeline welding in this embodiment includes a welding platform 1. On one side of the welding platform 1, there are multiple fixing components for fixing and clamping the pipeline to be welded. On one side of the multiple fixing components, there is a driving component for driving adjacent fixing components to move. On one side of each fixing component, there is a limiting component for aligning and restricting the clamped pipeline. The fixing component includes a sliding block 201 arranged on one side of the welding platform 1, a first clamping plate 202 fixedly installed on one side of the sliding block 201, and a second clamping plate 203 rotatably installed on one side of the first clamping plate 202. Both the first clamping plate 202 and the second clamping plate 203 are arranged in a semi-circular ring shape. On one side of the inner walls of the first clamping plate 202 and the second clamping plate 203, sliding grooves are opened. Inside both sliding grooves, sliders 9 are slidably installed. On one side of the inner walls of the first clamping plate 202 and the second clamping plate 203, rubber plates 5 are provided. Each rubber plate 5 is fixedly installed on one side of the adjacent slider 9. The rubber plate 5 will friction with the pipeline and the clamping plate to prevent the pipeline from sliding after being clamped. And the slider 9 can be used to replace the rubber plate 5 with a thickness adapted to the current pipeline. On one side of both the first clamping plate 202 and the second clamping plate 203, limiting plates 6 are fixedly installed. On one side of one of the limiting plates 6, there is a threaded column 7. One end of the threaded column 7 penetrates through the adjacent limiting plate 6 and is in threaded cooperation with the other limiting plate 6. The other end of the threaded column 7 is fixedly installed with a rotating block 8. Fix the two pipelines with the fixing components, and then use the driving component to move the fixing components so that the two pipelines can be tightly fitted together. The limiting component will limit one end of the pipeline to prevent the pipeline from shifting during the welding process. When the threaded column 7 rotates, the two limiting plates 6 will be locked, and then the first clamping plate 202 and the second clamping plate 203 can be locked and fixed.

[0031] Combined with Figure 1 and Figure 2 , On one side of the welding platform 1, a sliding groove is opened. The driving component includes a bidirectional threaded rod 301 arranged inside the sliding groove and a servo motor 302 arranged on one side of the welding platform 1. One end of the bidirectional threaded rod 301 penetrates through the welding platform 1 and is fixedly installed with the output end of the servo motor 302. Both sliding blocks 201 are in threaded cooperation with the bidirectional threaded rod 301. When the servo motor 302 is started, the bidirectional threaded rod 301 will rotate, thereby causing the sliding blocks 201 to move as well.

[0032] Combined with Figures 1 - 3 , The limiting component includes a limiting plate 401 fixedly installed on one side of the second clamping plate 203 and provided with a limiting opening, a sliding plate 402 slidably installed inside the limiting opening, and a limiting ring 403 fixedly installed on one side of the sliding plate 402. The inner diameter of the limiting ring 403 is the same as the combined inner diameter of the two rubber plates 5. The limiting ring 403 can sleeve the end of the pipeline to be welded, so that the welding position can be prevented from shifting due to external force during welding.

[0033] In the embodiment of the present application, the implementation principle of a fixing device for pipeline welding is as follows: When two sections of pipelines need to be welded, the rubber plate 5 adapted to the current pipeline is installed into the sliding grooves of the first clamping plate 202 and the second clamping plate 203 through the slider 9. Then, the second clamping plate 203 is opened, the pipeline is placed inside the first clamping plate 202, and then the second clamping plate 203 is closed. The threaded column 7 is rotated to cooperate with the limiting plate 6 to fix the second clamping plate 203 and the first clamping plate 202. Then, according to the size of the pipeline, the sliding plate 402 is pulled out to replace the limiting ring 403. The replaced limiting ring 403 is sleeved on one end of the pipeline to be welded to prevent the pipeline from being pushed by external force during welding, causing the welding end to shift. After the pipeline is fixed, the servo motor 302 is started. When the bidirectional threaded rod 301 rotates, the sliding block 201 will move, so that the pipeline fixed by the second clamping plate 203 and the first clamping plate 202 moves, avoiding the need for manual pushing by workers to make contact. Such a setting can not only clamp and fix the welded pipeline, but also make the clamped pipeline move and fit by itself, without the need for workers to manually push the two pipelines together.

[0034] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
