[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. During the manufacturing process, valves require quick-clamping devices for fixation. Currently, existing quick-clamping devices generally use electric push rods to drive clamping plates to hold and fix valves for processing. However, due to the irregular shape of valves, existing quick-clamping devices struggle to provide stable clamping, hindering stable valve fixation and reducing the convenience of valve processing and overall usability.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This utility model provides a technical solution: a quick clamping device for valve processing, including a stabilizing horizontal plate 1, with support legs 2 fixedly installed at the four corners of the lower surface of the stabilizing horizontal plate 1, and rectangular vertical plates 3 fixedly installed on the left and right sides of the upper surface of the stabilizing horizontal plate 1. A slidable U-shaped extension plate 4 is provided inside the rectangular vertical plate 3, and a positioning rod 5 inserted into the U-shaped extension plate 4 passes through the top of the rectangular vertical plate 3. A compression spring 6 is fixedly installed on the upper surface of the U-shaped extension plate 4, and a pulling vertical rod 7 is fixedly installed at the top of the compression spring 6. A pressing plate 8 is fixedly installed at the bottom of the pulling vertical rod 7. The compression spring 6, under its own elastic force, drives the pulling vertical rod 8. The vertical rod 7 and the pressing plate 8 move downwards to assist in clamping and fixing the valve, providing a better clamping and fixing effect. This facilitates more stable valve processing and effectively improves the convenience of valve processing. The upper surface of the stabilizing horizontal plate 1 is equipped with a rotatable annular rotating plate 9. By controlling the rotation of the handle rod 11, the rotating gear 12 meshes with the fixed rack 10, causing the annular rotating plate 9 and the valve to rotate at a uniform speed. This allows for more comprehensive valve processing, effectively improving the convenience and efficiency of valve processing. The bottom of the outer surface of the annular rotating plate 9 is fixedly mounted... A fixed rack 10 is installed, and a rotatable rotating handle 11 is provided on the right side of the upper surface of the stabilizing horizontal plate 1. A rotating gear 12 is fixedly installed on the bottom of the outer surface of the rotating handle 11. The fixed rack 10 meshes with the rotating gear 12. A cross-shaped stabilizing frame 13 is fixedly installed on the top of the inner wall of the annular rotating plate 9. A fixed bracket 14 is fixedly installed on the upper surface of the annular rotating plate 9. A rotatable pressing angle rod 15 is provided on the top of the fixed bracket 14. A rotatable clamping bracket 16 is provided on the top of the pressing angle rod 15. A rotatable pulling rod 17 is provided in the middle of the pressing angle rod 15. A rotatable pulling bracket 18 is provided at the bottom of the pulling rod 17. A connecting spring 19, which is connected to the upper surface of the cross stabilizer 13, is fixedly installed on the lower surface of the pull bracket 18. Under the action of its own elastic force, the connecting spring 19 drives the pull rod 17 and the pressing inclined rod 15 to move the clamping bracket 16 inward to perform clamping and fixing operations on the valve. This provides a better clamping and fixing effect on the valve, better ensures the stability of valve clamping, has a wider range of adaptability, can better adapt to valves of different sizes, helps to better process various types of valves, and improves the convenience of valve processing. A pull rod 20, which passes through the interior of the cross stabilizer 13, is fixedly installed on the lower surface of the pull bracket 18.

[0022] In order to improve the stability of rotation, an annular slider is fixedly installed on the lower surface of the annular rotating plate 9, and an annular groove is provided on the upper surface of the stabilizing horizontal plate 1. The annular slider is rotatably connected to the annular groove. The annular slider on the lower surface of the annular rotating plate 9 and the annular groove on the upper surface of the stabilizing horizontal plate 1 cooperate with each other to improve the stability of rotation.

[0023] In order to improve the stability of positioning in this utility model, multiple sets of positioning through holes are opened on both the left and right sides of the U-shaped extension plate 4. The size of the positioning through holes is adapted to the size of the positioning rod 5. The positioning through holes on the left and right sides of the U-shaped extension plate 4 and the positioning rod 5 cooperate with each other to improve the stability of positioning.

[0024] In order to facilitate stable sliding, a rectangular through hole is provided inside the rectangular vertical plate 3. The size of the rectangular through hole is adapted to the size of the U-shaped extension plate 4. The rectangular through hole inside the rectangular vertical plate 3 and the U-shaped extension plate 4 cooperate with each other to facilitate stable sliding.

[0025] In this utility model, in order to facilitate the pressing operation, four sets of pressing angle rods 15 are provided. The length of each of the four sets of pressing angle rods 15 is 450 mm. The four sets of pressing angle rods 15 cooperate with each other to facilitate the pressing operation.

[0026] In order to improve the anti-slip effect, the number of clamping brackets 16 is set to four. The inner side of each of the four clamping brackets 16 is provided with anti-slip texture. The anti-slip texture on the inner side of the four clamping brackets 16 increases the friction and improves the anti-slip effect.

[0027] In use, the valve to be processed is placed between the clamping brackets 16. Under the action of the connecting spring 19, the pulling bracket 18 is moved upward. The pulling bracket 18 moves the pulling rod 17, which in turn moves the pressing rod 15. The pressing rod 15 causes the clamping bracket 16 to rotate and clamp the valve. Then, the positioning rod 5 is pulled out, and the U-shaped extension plate 4 is moved to a suitable height. The positioning rod 5 is then inserted into the rectangular vertical plate 3 for limiting. At the same time, under the action of the compression spring 6, the pulling vertical rod 7 and the pressing plate 8 are moved downward to assist in clamping and fixing the valve. Then, the rotating handle 11 can be controlled to drive the rotating gear 12 to mesh with the fixed rack 10, causing the annular rotating plate 9 and the valve to rotate at a constant speed for processing.

[0028] In summary, this quick-clamping device for valve processing, through the connecting spring 19, drives the pulling rod 17 and the pressing inclined rod 15 to move the clamping bracket 16 inward under its own elastic force, thereby clamping and fixing the valve. It has a better clamping and fixing effect on the valve, can better ensure the stability of valve clamping, has a wider range of adaptability, can better adapt to valves of different sizes, helps to better process various types of valves, and improves the convenience of valve processing.

[0029] This quick-clamping device for valve processing uses a compression spring 6 to pull the vertical rod 7 and the pressing plate 8 downwards under its own elastic force to assist in clamping and fixing the valve. This provides a better clamping and fixing effect on the valve, helps to make the valve processing operation more stable, and effectively improves the convenience of valve processing.

[0030] This quick clamping device for valve processing drives the rotating gear 12 to mesh with the fixed rack 10 by controlling the rotating handle 11, thereby causing the annular rotating plate 9 and the valve to rotate at a uniform speed. This facilitates more comprehensive valve processing operations, effectively improving the convenience and efficiency of valve processing, and making it easier to perform processing.
