[0002] Valves, as key components for fluid control, are widely used in numerous fields, including petroleum, chemical, natural gas, electricity, and water supply and drainage. Valves in different fields vary significantly in size, shape, material, and process requirements, but all share strict requirements for machining accuracy and sealing. For example, in the petrochemical industry, valves must withstand high temperatures, high pressures, and corrosive media. Their machining accuracy directly affects the valve's sealing performance and reliability. Leakage can cause serious safety accidents and environmental pollution. In the power industry, valve control accuracy is crucial to the stable operation of power generation equipment, and any slight error can affect the efficiency and safety of the entire power system.

However, due to the inconsistency of valve sizes, the jaws of traditional clamping mechanisms are usually fixed in size, resulting in poor adaptability. Therefore, a valve clamping device for valve processing has been proposed to address this issue. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 2The present invention provides an embodiment of a valve clamping device for valve processing, comprising a base 1 and a valve workpiece 21. The base 1 of the valve clamping device is the basic support component of the entire device and is typically made of thick cast iron. It is generally in the shape of a cube-shaped flat plate with a polished, relatively flat top. A mounting plate 2 is fixedly connected to the top of the base 1. The mounting plate 2 is typically a rectangular plate structure that provides a mounting base for the subsequent clamping structure. Two slide rails 4 are fixedly connected to the right side of the mounting plate 2. The length of the slide rails 4 should meet the sliding travel requirements of the subsequent structure during operation, ensuring that they can flexibly move within a certain range to accommodate the clamping operation of valve workpieces 21 of different sizes. Two sliding plates 5 are slidably connected to the outer portions of the two slide rails 4. The sliding plates 5 are typically flat plates with a shape and size that match the slide rails 4. The sliding plates 5 are made of high-strength steel metal with excellent mechanical properties and wear resistance. A clamping member 6 is fixedly connected to the right side of the two sliding plates 5. The clamping member 6 directly contacts the valve workpiece 21 and performs the clamping function. The shape and structure of the clamping member 6 are designed according to the appearance characteristics of the valve workpiece 21. It is an arc structure to ensure that it can fit tightly with the surface of the valve workpiece 21 and provide a stable clamping force. The adjacent sides of the two sliding plates 5 are fixedly connected with a rack 7. The rack 7 can move synchronously with the sliding plate 5, and the subsequent structure drives the rack 7 to slide and then realizes the sliding clamping effect. The left side of the mounting vertical plate 2 is fixedly connected with a motor 8. The motor 8 is the power source of the entire clamping device. The sliding plate 5 is driven to slide by the force of the rotation of the driving end. The driving end of the motor 8 is fixedly connected with a gear 9. The gear 9 is the key component for realizing the transmission between the motor 8 and the rack 7. By rotating, the meshing rack 7 is driven to slide and the direction of the force is changed. The top of the mounting vertical plate 2 is fixedly connected with the mounting vertical plate 2 3. The mounting vertical plate 2 3 provides an installation basis for the subsequent internal support assembly. The left side of the mounting vertical plate 2 3 is fixedly connected with an internal support assembly to prevent the valve workpiece 21 from being deformed due to excessive clamping force.

[0033] Reference Figure 2 The adjacent sides of the two racks 7 mesh with the exterior of the gear 9. When the motor 8 drives the gear 9 to rotate, the gear 9, through meshing with the rack 7, converts the rotational motion into linear motion of the rack 7. The exteriors of the two racks 7 are slidably connected to the interiors of the two sliding plates 5, providing sufficient space for the sliding of the racks 7 and ensuring the feasibility of clamping. The adjacent sides of the two clamping members 6 contact the exterior of the valve workpiece 21. The shape of the clamping members 6 is generally designed based on the arc-shaped characteristics of the valve workpiece 21 to ensure a close fit with the surface of the valve workpiece 21 and provide stable clamping force.

[0034] Reference Figures 3 and 4The inner support assembly includes a telescopic sleeve 10. The right side of the telescopic sleeve 10 is fixedly connected to the left side of the mounting plate 2 3. The telescopic sleeve 10 is used to extend the inner support structure into the left clamping structure to share part of the clamping force and reduce deformation. The interior of the telescopic sleeve 10 is fixedly connected with an electric push rod 11. The electric push rod 11 is the power source of the inner support assembly. The extension of the driving end drives the subsequent structure to open. The interior of the telescopic sleeve 10 is slidably connected with a sliding head 14. The main function of the sliding head 14 is to drive the subsequent structure to move under the push of the electric push rod 11, so that the inner support structure is opened or closed. Contraction, the external rotation connection of the telescopic sleeve 10 is provided with a plurality of rotating bars 12, and the far sides of the plurality of rotating bars 12 are rotationally connected to the inner support plate 13, and the inner support plate 13 is an arc-shaped structure, which can fit tightly with the inner surface of the valve workpiece 21 to provide effective internal support force, and the external rotation connection of the sliding head 14 is provided with a plurality of rotating bars 2 15, and the far sides of the plurality of rotating bars 2 15 are rotationally connected to the close sides of the plurality of inner support plates 13 respectively. The main function of the rotating bar 2 15 is to drive the inner support plate 13 to move when the sliding head 14 moves, so as to realize the expansion and contraction of the inner support plate 13.

[0035] Reference Figure 5 The bottom of the base 1 is fixedly connected to a motor 2 16. The motor 2 16 is a structure that provides power for cleaning the table surface. The driving end of the motor 2 16 is fixedly connected to a turntable 17. The turntable 17 is a key component that converts the rotational motion of the motor 2 16 into other forms of motion. The circular motion of the convex button on its top drives the subsequent structure to move back and forth. The top of the turntable 17 is rotatably connected to a rotating plate 18. When the turntable 17 rotates, the rotating plate 18 will make a circular motion with the rotation of the turntable 17. The front side of the rotating plate 18 is rotatably connected to a scraper 19. Due to the connection relationship between the rotating plate 18 and the scraper 19, it will also drive the scraper 19 to reciprocate. An empty slot 20 is provided on the top of the base 1. The empty slot 20 is used to drop the scraped metal particles to the same position for easy cleaning. The outer portion of the scraper 19 is slidably connected to the inner portion of the mounting vertical plate 1 2, and the outer portion of the scraper 19 is slidably connected to the inner portion of the mounting vertical plate 2 3, thereby providing a limit and guide for the sliding of the scraper 19.

[0036] Working Principle: First, the staff places the valve workpiece 21 between the two clamping parts 6, and by starting the power switch of the motor 8, the driving end rotates and drives the gear 9 to rotate, thereby driving the two racks 7 meshing with the gear 9 to move toward the adjacent side, and then pulls the two sliding plates 5 to slide toward the adjacent side, driving the two clamping parts 6 to clamp the outside of the valve workpiece 21. The clamping device can flexibly adjust the spacing of the clamping parts 6 through the transmission method of the gear 9 and the rack 7 to adapt to valves of different specifications and sizes. Whether it is a small valve or a large valve, it can be accurately clamped by the drive of the motor 8. This flexibility makes the device widely applicable when facing the production or processing tasks of various types of valves.

[0037] Next, the telescopic sleeve 10 is opened and extended into the interior of the valve workpiece 21. By turning on the switch of the electric push rod 11, the extension of the driving end causes the sliding head 14 to slide to the left, which in turn causes the multiple rotating bars 15 to rotate, and finally causes the multiple internal support plates 13 to expand outward, generating an internal support force. This internal support force is applied at multiple locations within the valve, cooperating with the external clamping force to effectively disperse the pressure on the valve. When the external clamping member 6 applies a clamping force to the valve, the expansion of the internal support plates 13 can offset some of the inward compressive stress generated by the clamping, preventing the valve from deforming due to excessive local force during the clamping process.

[0038] Finally, during the machining of valve workpiece 21, a large amount of metal particles remain on the bottom of base 1. At this point, motor 2 16 is turned on, and the drive end of motor 2 16 drives turntable 17 to rotate, thereby driving rotating plate 18 to reciprocate. This in turn pulls scraper 19 to slide back and forth, scraping the metal particles from the top of base 1 through slot 20 and onto the ground for unified cleaning. Timely and effective removal of metal particles generated during valve machining and remaining on the bottom of base 1 can keep the table clean and extend the service life of the equipment.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
