Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting production tools, in particular to a clamping device for pipe fitting production. Background Art

[0002] The clamping equipment used in pipe fitting production is designed to clamp and fix various pipes or pipe fittings during processing to ensure processing accuracy and safety. This type of equipment usually includes the following features and components:

[0003] 1. Multifunctional clamping heads: These clamping heads can adapt to pipes of various sizes and materials, including but not limited to steel pipes, copper pipes, plastic pipes, etc. By replacing or adjusting the clamping heads, the equipment can flexibly respond to the processing needs of pipes of different specifications.

[0004] 2. Precise positioning system: In order to ensure processing accuracy, the clamping equipment is usually equipped with a high-precision positioning system. This can be mechanical, electronic or achieved through a visual system to ensure that each processing can achieve consistent standards and quality.

[0005] 3. Stable support structure: The clamping equipment needs to have sufficient stability to resist the vibration and force generated during the processing. This is usually achieved by weighting and strengthening the base of the equipment and optimizing the structural design to keep the equipment stable during operation.

[0006] 4. Automatic and semi-automatic operation: With the development of technology, many clamping equipment are designed for automatic or semi-automatic operation, and the clamping action is controlled by electric, pneumatic or hydraulic systems. This not only improves work efficiency, but also reduces labor intensity and improves operational safety.

[0007] 5. Quick change mechanism: In the process of processing different pipes or fittings, it is necessary to quickly change the clamping head or adjust the clamping position. Therefore, many equipment are designed with quick change mechanisms or easy-to-adjust structures to shorten the adjustment and switching time of the equipment.

[0008] 6. Durability and maintenance: The clamping equipment in pipe processing usually faces large physical loads and challenging environments (such as dust, liquid splashing, etc.), so these devices are designed with special attention to durability and easy maintenance.

[0009] Clamping equipment plays a vital role in pipe production lines. They not only improve production efficiency and ensure processing quality, but also ensure the safety of workers. With the advancement of technology, clamping equipment is developing towards higher automation and intelligence to meet more stringent and diversified production needs.

[0010] The application number is CN202311474302.8. The pipe clamping device for automobile exhaust system production relates to the technical field of pipe processing tooling for automobile production. The outer clamping part is arranged on the connecting frame, and it is clamped between the connecting frame and the frame. The inner clamping part is arranged on the frame, and it is arranged in coordination with the outer clamping part. It arranges the inner clamping structure and the outer clamping structure, and makes the two cooperate with each other to realize the clamping of the pipe end, and makes the inside of the pipe receive support, so as to avoid deformation of the side wall of the pipe during clamping, but it cannot guarantee that the clamping assembly can continue to remain stable when clamping the pipe.

[0011] Therefore, in view of this, research and improvement are conducted to the existing deficiencies, and a clamping device for pipe production is proposed. Utility Model Content

[0012] The purpose of the utility model is to provide a clamping device for pipe production to solve the problems raised in the above background technology.

[0013] To achieve the above object, the utility model provides the following technical solution: a clamping device for pipe production, comprising: a base, a clamping ring is arranged at the top of the base, and a stabilizing structure is arranged on the inner side of the clamping ring;

[0014] A positioning plate is arranged at the front end of the clamp ring, a small-diameter ring piece is arranged at the front end of the positioning plate, and an auxiliary structure is arranged at the outer side of the small-diameter ring piece.

[0015] Furthermore, the stabilizing structure includes a slider assembly, an arc-shaped clamping layer and an embedded ring. The inner side of the clamping ring is provided with an embedded ring, the inner side of the embedded ring is provided with an arc-shaped clamping layer, and the outer side of the embedded ring is provided with a slider assembly. The slider assembly forms a sliding structure between the clamping ring and the embedded ring, which facilitates the inner ring to rotate on the inner side of the clamping ring.

[0016] Furthermore, the arc-shaped card layer is made of a plastic foam material, which facilitates the arc-shaped card layer to deform when squeezed, and also facilitates the arc-shaped card layer to restore its shape after being subjected to pressure.

[0017] Furthermore, the arc-shaped clamping layer has a semi-arc shape, which is convenient for the pipeline to penetrate.

[0018] Furthermore, the radius of the embedded ring is slightly smaller than the radius of the clamping ring, which facilitates the installation of the embedded ring.

[0019] Furthermore, the auxiliary structure includes a cross bar, a slider and a rotating assembly. Sliders are provided on both sides of the small-diameter ring piece. A cross bar is provided through the outer transverse groove of the slider. A rotating assembly is provided at one end of the cross bar. A rotating structure is formed between the rotating assembly and the positioning plate to facilitate the rotating assembly to drive the cross bar to rotate.

[0020] Furthermore, a sliding structure is formed between the slider and the cross bar, so that the slider can drive the small-diameter ring piece to move on the inner side of the cross bar.

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

[0022] 1. The utility model drives the small-diameter ring piece to move on the inner side of the cross bar through the slider. When the small-diameter ring piece moves to a suitable position, the rotating assembly is rotated, and the rotating assembly drives the small-diameter ring piece and the cross bar to rotate. When the center of the small-diameter ring piece and the center of the clamp ring are on the same straight line, the rotation is stopped. In this way, a pipe with a smaller diameter can pass through the small-diameter ring piece for clamping and processing, and has the following effects and advantages:

[0023] 1. Precise clamping: The slider drives the small-diameter ring piece to move along the crossbar to the appropriate position, and then the rotating assembly controls the small-diameter ring piece to rotate until it is aligned with the center of the clamp ring. This design allows the pipe fitting to be stably clamped at a precisely predetermined position, ensuring the accuracy of the processing process.

[0024] 2. Strong adaptability: This mechanism allows the equipment to adapt to pipes of different diameters. By simply adjusting the position and rotation angle of the small-diameter ring, the equipment can easily adapt to pipes of various sizes, enhancing the versatility and flexibility of the equipment.

[0025] 3. Easy to operate: The design of the slider and rotating assembly makes the adjustment process automatic or semi-automatic, greatly improving the convenience of operation, reducing the requirements for operator skills, and improving production efficiency.

[0026] 4. Stable and reliable: Ensure that the center of the small-diameter ring is aligned with the center of the clamping ring. Such fine control can greatly improve the stability of the clamping process, reduce errors in the processing process, and avoid product scrap rate caused by unstable clamping.

[0027] 5. Improve production efficiency: Quickly and accurately clamping and positioning pipes with smaller diameters can significantly improve the operating efficiency of the production line, reduce the time wasted on adjusting the clamping equipment, and speed up the production cycle.

[0028] 6. Protect materials: By carefully controlling the clamping force and position, unnecessary stress or damage to the pipe material can be avoided. This is especially suitable for processing pipes with high surface treatment requirements or fragile materials.

[0029] 7. Expand the scope of application: This design is not only suitable for pipes with smaller diameters, but also can be applied to a wider range of pipe diameters by adjusting the parameters of the slider and the rotating assembly, thereby expanding the application range of the equipment and improving the return on investment. This design optimizes the pipe clamping process, improves processing accuracy and efficiency, and has good adaptability and ease of operation. For companies producing pipes, it is a key technology to enhance competitiveness;

[0030] 2. The utility model inserts the inner ring through the pipe. At the same time, since the arc-shaped card layer is made of plastic foam material, the arc-shaped card layer begins to deform under the extrusion of the pipe. Then the inner ring is rotated, and the slider assembly cooperates with the inner ring to rotate. In this way, the pipe and the arc-shaped card layer inside the inner ring are tightly fitted to prevent the pipe from shaking. The effects and advantages can be summarized as follows:

[0031] 1. Efficient shock absorption and anti-shaking: The deformation of the arc-shaped card layer under the extrusion of the pipe can provide good shock absorption, so that the fixed pipe can remain stable even if it encounters vibration or external force during processing, which greatly reduces processing errors and improves processing quality.

[0032] 2. Pipeline surface protection: The arc-shaped card layer made of plastic foam material has a good protective effect on the pipeline surface, avoiding scratches or wear caused by hard objects directly contacting the pipeline. It is particularly suitable for pipeline processing with high surface treatment requirements or fragile materials.

[0033] 3. Adaptability and flexibility: By rotating the embedded ring and cooperating with the slider assembly for fine adjustment, this design can easily adapt to pipes of different diameters and materials, enhancing the versatility and flexibility of the equipment.

[0034] 4. Simplify the operation process: This clamping mechanism simplifies the clamping process of the pipe, making the operation more convenient. The clamping can be completed quickly with a small number of actions, reducing the line change time of the equipment and improving production efficiency.

[0035] 5. Improve work efficiency: The fast and stable clamping mechanism enables the production line to operate more efficiently, reducing the repetitive processing and adjustment time caused by unstable clamping, which helps to improve the overall production capacity.

[0036] 6. Tailor-made clamping solution: Through the careful design of the embedded ring and the arc-shaped clamping layer, a clamping solution that can be tailored according to the size and shape of the pipe is provided, ensuring high precision and high repeatability of the processing process.

[0037] 7. Reduce equipment maintenance costs: The deformable arc-shaped clamping layer not only provides a large contact area to disperse pressure, but also reduces the wear of the embedded ring and slider components, thereby reducing the long-term operation and maintenance costs of the equipment. This clamping mechanism not only optimizes the stability and precision of pipe processing, but also improves the convenience of operation and production efficiency. At the same time, it can effectively protect the surface of the pipe, adapt to a variety of processing requirements, and provide reliable technical support for high-quality and efficient pipe processing.

[0063] Working principle: When using the clamping device for pipe fitting production, first install the base 6 on the working panel of the target equipment, and combine the positioning plate 5 with the base 6. At this time, the pipeline passes through the clamp ring 1, and the embedded ring 203 inside the clamp ring 1 is also passed through by the pipeline, and the embedded ring 203 is rotated.
