Description

Technical Field

[0001] This utility model relates to the field of slender tube processing technology, specifically to a clamp suitable for quick locking and fixing of slender tubes. Background Technology

[0002] In metal smelting processes, slender tubing plays an indispensable role. It not only transports gaseous and liquid media and acts as a heat exchanger to regulate temperature, but also serves as a protective barrier against contamination, provides structural support to ensure equipment stability, and is equipped with monitoring devices for process control. Furthermore, slender tubing is used for waste gas emission and treatment, ensuring environmental protection, and as part of a vacuum system in special smelting processes requiring vacuum levels. In summary, by undertaking physical connections, transportation tasks, and optimizing process flows, slender tubing is crucial for improving product quality and ensuring safe production; therefore, the processing quality of slender tubing affects its subsequent use.

[0003] Slender tubular components need to be fixed during processing. However, due to the fast adjustment range and speed of current clamping devices, excessive force can easily be applied when clamping the workpiece, causing damage. At the same time, existing clamping devices also have a series of problems such as complex structure, large size, and relatively high manufacturing cost. Summary of the Invention

[0004] In view of the shortcomings of the above-mentioned slender tubes being easily damaged during processing, and the clamping devices being complex, bulky, and costly to manufacture, this utility model provides a clamp that is suitable for quick locking and fixing of slender tubes, while being small in size, simple in structure, and low in manufacturing cost.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A clamp suitable for quick locking and fixing of slender pipe fittings includes a concave base and a chuck that mates with the concave base. The concave base has arc-shaped notches on both sides of the middle, connecting the central concave shape. A pin is fixed at one end of the concave base near the top, and a limit strip is detachably installed at the other end. One end of the chuck is rotatably fitted onto the pin, and the other end has a through hole that mates with the limit strip. The limit strip passes through the concave base and the through hole to complete the limiting. The chuck has an arc-shaped notch at the position corresponding to the arc-shaped notch, and a threaded hole connecting the arc-shaped notch is also provided in the middle of the top of the chuck. A limit screw is provided in the threaded hole.

[0007] Furthermore, the concave base includes two fixing blocks and two side plates. The two side plates are connected together by the fixing blocks to form a concave structure. An arc-shaped notch is provided in the middle of the upper end of each side plate, and symmetrical circular holes are provided on both sides of the notch. A pin is fixedly installed in one of the circular holes, while the circular hole on the other side engages with a limiting strip. The separate design of the fixing blocks and side plates facilitates the processing of the concave base, effectively reduces production costs, and facilitates the promotion and use of forming fixtures.

[0008] Furthermore, the side plate and the fixing block are detachably connected together by screws. The fixing block and the side plate are assembled and disassembled using screws. During use, the side plates with different sizes of arc-shaped notches can be flexibly adjusted and replaced according to actual needs, which can effectively adapt to slender pipes of different diameters, enhance the versatility and flexibility of the equipment, and also facilitate maintenance and component replacement, reducing long-term operating costs.

[0009] Furthermore, the chuck includes a connecting plate and two clamping plates. The connecting plate has a threaded hole in the middle for engaging a limiting screw, and the clamping plates are connected to both sides of the connecting plate to form a concave chuck structure. The clamping plates have an arc-shaped notch in the middle, and the clamping plates on both sides of the arc-shaped notch also have through holes and mounting holes, wherein the through holes are detachably engaged with the limiting strip, and the mounting holes are rotatably engaged with the pin. The opening and closing of the chuck can be completed with a simple rotation action, without the need for a complicated adjustment process, thereby greatly shortening the preparation time and improving work efficiency. At the same time, because the arc-shaped notch on the clamping plate precisely matches the arc-shaped notch on the base, it ensures that the slender tube is subjected to uniform force throughout the entire processing, avoiding the risk of damage to the slender tube due to excessive local force.

[0010] Furthermore, the connecting plate and the clamping plate are detachably connected together by screws. The connecting plate and clamping plate are assembled detachably using screws, allowing for flexible adjustment and replacement of clamping plates with different sizes of arc-shaped notches according to actual needs. This effectively adapts to slender pipes of different diameters, enhancing the equipment's versatility and flexibility, while also facilitating maintenance and component replacement, making maintenance more convenient.

[0011] Furthermore, the main body of the limiting screw is a threaded column, and a rotating handle is fixedly installed on the top of the threaded column. In use, the threaded column is driven by the rotating handle to rotate within the threaded hole, pressing against the slender tube to achieve limiting. Conversely, it can release the limiting of the slender tube by controlling the rotation of the rotating handle. The auxiliary limiting of the slender tube can be completed by controlling the rotation of the rotating handle. The operation is simple and can better restrict the slender tube in the fixture.

[0012] Furthermore, a spring is also fitted around the outer periphery of the threaded post. The spring provides a continuous preload between the threaded post and the slender tube, ensuring that the slender tube remains stably clamped even during slight vibrations or movement, avoiding processing errors or damage risks caused by loosening. It can also buffer direct pressure to a certain extent, preventing damage to the workpiece surface caused by over-tightening. The presence of the spring can automatically compensate for wear caused by repeated operation or material aging, or for manufacturing tolerances, ensuring the effectiveness of use.

[0013] How to use this utility model:

[0014] The circular notch and the arc-shaped notch work together to form a circular notch for fitting slender tubes. The chuck can rotate up and down around the fixing pin on the concave base plate. The limiting strip connects or separates from the through hole of the concave base and the chuck to limit and release the chuck. In use, first take out the limiting strip, then control the chuck to rotate along the pin to open it. Then place the slender tube to be limited into the arc-shaped notch of the concave base. Then rotate the chuck so that the circular notch abuts against the top of the slender tube. Then insert the limiting strip into the concave base. The limiting strip passes through one side of the concave base, the through hole of the chuck, and the other side of the concave base in sequence. Then screw the limiting screw into the circular notch so that it abuts against the slender tube. This completes the limiting of the chuck. At this time, the slender tube is stably limited in the fixture, and then the slender tube can be processed.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] 1. This utility model achieves uniform and stable clamping of slender tubes through the optimized design of the concave base and the chuck, effectively avoiding the workpiece damage caused by uneven or excessive force in traditional devices; its simple and compact structure not only reduces the number of parts and assembly difficulty, but also lowers material and manufacturing costs, making the chuck smaller in size and adaptable to narrower working environments. At the same time, the quick-lock design greatly facilitates operation, improves work efficiency, and reduces processing preparation time.

[0017] 2. The separate design of the fixing block and the side plate of this utility model facilitates the processing of the concave base, effectively reduces production costs, facilitates the promotion and use of forming fixtures, and the fixing block and the side plate are assembled with screws for easy disassembly. During use, the side plates with different sizes of arc-shaped notches can be flexibly adjusted and replaced according to actual needs, which can effectively adapt to slender pipes of different diameters. It also facilitates maintenance and component replacement, reducing the cost of long-term use.

[0018] 3. The connecting plate and clamping plate of this utility model are assembled and disassembled by screws, which not only facilitates the production and processing of components, but also allows for flexible adjustment and replacement of clamping plates with different sizes of arc-shaped notches according to actual needs during use. This effectively adapts to slender pipes of different diameters, enhances the versatility and flexibility of the equipment, and facilitates maintenance and use.

[0019] 4. The limiting screw of this utility model can quickly complete the auxiliary limiting of slender pipes by controlling the rotation of the screw to drive the threaded column. This enhances the limiting of slender pipes and can better confine them in the fixture. The spring sleeved on the outer periphery of the threaded column can provide continuous preload, ensuring that even if there is slight vibration or movement during processing, the slender pipe can maintain a stable clamping state, avoiding the risk of processing errors or damage caused by loosening.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1: A clamp suitable for quick locking and fixing of slender pipe fittings includes a concave base 1 and a chuck 2 that mates with the concave base 1. The concave base 1 has arc-shaped notches on both sides of the middle concave shape, and a pin 3 is fixedly installed at one end of the concave base 1 near the top, while a limit strip 4 is detachably installed at the other end. One end of the chuck 2 is rotatably fitted onto the pin 3, and the other end has a through hole that mates with the limit strip 4. The limit strip 4 passes through the concave base 1 and the through hole to complete the limiting. The chuck 2 has an arc-shaped notch at the position corresponding to the arc-shaped notch, and a threaded hole in the middle of the top of the chuck 2 that connects to the arc-shaped notch is also provided. A limit screw 5 is provided in the threaded hole.

[0025] The circular notch and the arc-shaped notch work together to form a circular notch for fitting slender tubes. The chuck 2 can rotate up and down around the fixing pin on the concave base plate. The limiting strip 4 can be connected or separated from the concave base 1 and the through hole of the chuck 2 to limit and release the chuck 2. In use, first take out the limiting strip 4, then control the chuck 2 to rotate along the pin 3 to open it. Then put the slender tube that needs to be limited into the arc-shaped notch of the concave base 1. Then rotate the chuck 2 so that the circular notch abuts against the top of the slender tube. Then insert the limiting strip 4 into the concave base 1. The limiting strip 4 passes through one side of the concave base 1, the through hole of the chuck 2 and the other side of the concave base 1 in sequence. Then screw the limiting screw 5 into the circular notch so that it abuts against the slender tube. At this time, the limiting of the chuck 2 is completed. The slender tube is now stably limited in the clamp, and then the slender tube can be processed.

[0026] Example 2: Unlike Example 1, the concave base 1 includes two fixing blocks 11 and two side plates 12. The two side plates 12 are connected together by the fixing blocks 11 to form a concave structure. An arc-shaped notch is provided in the middle of the upper end of each side plate 12, and symmetrical circular holes are provided on both sides of the notch. A pin 3 is fixedly installed on one of the circular holes, and the circular hole on the other side cooperates with a limiting strip 4. The separate design of the fixing blocks 11 and the side plates 12 facilitates the processing of the concave base 1, effectively reduces production costs, and facilitates the promotion and use of forming fixtures.

[0027] The chuck 2 includes a connecting plate 21 and two clamping plates 22. The connecting plate 21 has a threaded hole in the middle for engaging the limiting screw 5, and the clamping plates 22 are connected to both sides of the connecting plate 21 to form a concave structure chuck 2. The clamping plates 22 have an arc notch in the middle, and the clamping plates 22 on both sides of the arc notch also have through holes and mounting holes, respectively. The through holes are detachably engaged with the limiting strip 4, and the mounting holes are rotatably engaged with the pin 3. The opening and closing of the chuck 2 can be completed by a simple rotation action, without the need for a complicated adjustment process, thereby greatly shortening the preparation time and improving work efficiency. At the same time, because the arc notch on the clamping plate 22 is precisely engaged with the arc notch on the base, it ensures that the slender tube is subjected to uniform force throughout the entire processing, avoiding the risk of damage to the slender tube due to excessive local force.

[0028] Example 3: Unlike Example 2, the side plate 12 and the fixing block 11 are detachably connected by screws. The fixing block 11 and the side plate 12 are assembled detachably using screws. During use, the side plate 12 with different sizes of arc-shaped notches can be flexibly adjusted and replaced according to actual needs, effectively adapting to slender pipes of different diameters. This enhances the versatility and flexibility of the equipment, while also facilitating maintenance and component replacement, reducing long-term operating costs.

[0029] The connecting plate 21 and the clamping plate 22 are detachably connected together by screws. The connecting plate 21 and the clamping plate 22 are assembled and disassembled by screws. During use, the clamping plate 22 with different sizes of arc-shaped notches can be flexibly adjusted and replaced according to actual needs, which can effectively adapt to slender pipes of different diameters, enhance the versatility and flexibility of the equipment, and also facilitate maintenance and component replacement, making maintenance more convenient.

[0030] Example 2: The difference from Example 1 is that the main body of the limiting screw 5 is a threaded column, and a rotating handle 51 is fixedly installed on the top of the threaded column. In use, the threaded column is driven by the rotating handle 51 to rotate within the threaded hole, pressing against the slender tube to achieve limiting. Conversely, it can release the limiting of the slender tube by controlling the rotation of the rotating handle 51. The auxiliary limiting of the slender tube can be completed by controlling the rotation of the rotating handle 51. The operation is simple and can better restrict the slender tube in the clamp.

[0031] A spring 52 is also fitted around the outer periphery of the threaded post. The spring 52 provides a continuous preload between the threaded post and the slender tube, ensuring that the slender tube remains stably clamped even if slight vibration or movement occurs during processing. This avoids processing errors or damage risks caused by loosening and can also buffer direct pressure to a certain extent, preventing damage to the workpiece surface caused by over-tightening. The presence of the spring 52 can automatically compensate for wear caused by repeated operation or material aging, or for manufacturing tolerances, ensuring the effectiveness of use.
