Description
Technical Field
[0001] This application relates to the field of machining equipment, and in particular to a highly compatible valve body clamp. Background Technology
[0002] In the field of machining, especially in the production of multi-port hydraulic valves, precise positioning and secure fixing of the valve body are crucial for ensuring product quality. With the increasing level of industrial automation, efficient and reliable fixture design has become an important means of improving production efficiency. Existing fixture technology has developed into various types, such as general-purpose three-jaw chucks, four-jaw single-acting chucks, and various special-purpose combination fixtures. These devices are widely used in the machining of different types of workpieces, greatly improving manufacturing accuracy and production speed. To meet the machining needs of valve bodies of different types and sizes, common solutions currently include using general-purpose three-jaw chucks, four-jaw single-acting chucks, or special-purpose combination fixtures. General-purpose three-jaw chucks are suitable for rapid positioning of round workpieces, while four-jaw single-acting chucks can flexibly adjust the position of each jaw to adapt to non-circular workpieces. Furthermore, special-purpose combination fixtures, through modular design, can be customized according to the specific requirements of the workpiece, further improving the application range and flexibility of the fixtures. However, regardless of the type of fixture, they generally share a common characteristic: only one valve body can be fixed at a time. This leads to low machining efficiency, especially in mass production environments, where this problem is particularly prominent. While the aforementioned fixtures meet basic machining requirements to some extent, their main drawback is their inability to perform simultaneous multi-station machining. Since only one valve body can be fixed at a time, this not only increases material change time and operational complexity but also limits the overall production line capacity. Therefore, designing a highly compatible fixture capable of simultaneously fixing multiple valve bodies has become a pressing technical challenge. Summary of the Invention
[0003] The purpose of this application is to overcome the above-mentioned technical problems and provide a highly compatible valve body clamp.
[0004] A highly compatible valve body clamp includes a fixed platform, which is a polygonal prism. Multiple positioning platforms are provided on the side walls of the fixed platform, and each positioning platform is equipped with a clamping assembly. The clamping assembly forms two positions on the positioning platform for clamping valve bodies. By adopting this technical solution, users can clamp two valve bodies on each positioning platform, thus fixing multiple valve stems on the fixed platform at once, instead of the traditional method of fixing only one valve stem at a time. This allows for simultaneous processing of multiple valve stems, improving processing efficiency. Preferably, the clamping assembly includes baffles on both sides of the positioning platform, a positioning plate in the middle of the positioning platform, and clamping plates slidably connected to the sides of the positioning plates near the baffles. The clamping plates and baffles form clamping positions. By adopting this technical solution, when installing the valve body, the user places the valve body between the positioning plate and the baffles, and the sliding clamping plates press the valve body against the baffles, thus fixing the valve body between the clamping plates and the baffles. Preferably, the positioning plate has sliding grooves on both sides, which are inclined from the side of the positioning plate away from the positioning platform towards the center of the positioning plate. A sliding block is fixedly connected to the clamping plate, and the sliding block is inclined from the side of the clamping plate away from the positioning platform towards the side away from the positioning plate. By adopting the above technical solution, when the user slides the clamping plate downwards, the inclined surface on the sliding block slides within the inclined surface of the sliding groove, making the clamping plate more tightly contact the valve body as it slides towards the positioning platform, resulting in a more stable connection to the valve body. Preferably, the positioning platform is detachably connected to the side wall of the fixed platform. By adopting the above technical solution, when the user uses the product, it is easy to remove the positioning platform, install the valve body on the positioning platform first, and then fix the valve body on the positioning platform, facilitating the disassembly and installation of the valve body. Preferably, the side wall of the fixed platform is provided with multiple pneumatic claws, and the side wall of the positioning platform is fixedly connected with multiple insertion posts for insertion into the pneumatic claws. By adopting the above technical solution, when the user uses the device, the insertion post is positioned within the pneumatic jaws, which clamp the insertion post, automatically fixing the positioning platform to the fixed platform, facilitating automatic fixing and disassembly of the worktable. Preferably, a lifting ring is provided on one side of the positioning platform. By adopting the above technical solution, the lifting ring facilitates the lifting and transportation of the positioning platform when the user uses it. Preferably, a buffer assembly is provided at the bottom of the fixed platform; the buffer assembly includes multiple buffer springs, with a buffer plate fixedly connected to the end of each buffer spring away from the fixed platform, and the buffer plate abuts against the end of the positioning platform. By adopting the above technical solution, when the lifting positioning platform is installed on the fixed platform, the end of the positioning platform impacts the buffer plate, and the tension of the buffer springs buffers the impact, thereby preventing direct impact between the end of the positioning platform and the fixed platform and reducing wear between the positioning platform and the fixed platform. Preferably, a buffer rubber pad is provided on the side wall of the fixed platform. By adopting the above technical solution, the buffer rubber pad is used to reduce the impact between the positioning platform and the fixed platform during use, thereby reducing the wear between the positioning platform and the fixed platform.Preferably, anti-collision posts are provided at the four corners of the side wall of the fixed platform. By adopting the above technical solution, the anti-collision posts can reduce the impact between the hoisted positioning platform and the fixed platform during use, thereby reducing wear between the positioning platform and the fixed platform.

Detailed Implementation
[0010] The following will be combined with the appendix Figure 1-4 The technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of the present invention without creative effort, and these embodiments are also within the protection scope of the present invention. This application provides a highly compatible valve body clamp, referring to... Figure 1 The system includes a fixed platform 1, which is polygonal in shape. Multiple positioning platforms 2 are provided on the side walls of the fixed platform 1. Each positioning platform 2 is equipped with a clamping assembly 3, which forms two positions on the positioning platform 2 for clamping valve bodies. By clamping two valve bodies on each positioning platform 2, multiple valve stems can be fixed on the fixed platform 1 at once, replacing the traditional method of fixing only one valve stem at a time. This allows for the simultaneous processing of multiple valve stems, significantly improving processing efficiency.
[0011] Specifically, the fixed platform 1 can be in the shape of a square, rectangle, or polygon, or other prismatic shapes, to accommodate valve bodies of different sizes and shapes. The figure shows the fixed platform 1 as a square prism, but it is not limited to square prisms. The material of the fixed platform 1 can be high-strength steel or aluminum alloy to ensure sufficient strength and durability. The surface of the fixed platform 1 can be anodized to increase wear resistance and corrosion resistance.
[0012] Reference Figure 2 and Figure 3 The side wall of the fixed platform 1 is equipped with multiple pneumatic grippers 11, and the side wall of the positioning platform 2 is fixedly connected with multiple insertion posts 21. The insertion posts 21 are used to insert into the pneumatic grippers 11. When the insertion posts 21 are inserted into the pneumatic grippers 11, the pneumatic grippers 11 clamp and secure the insertion posts 21, which can automatically fix the positioning platform 2 to the fixed platform 1, facilitating the automatic fixing and disassembly of the worktable.
[0013] The fixed pneumatic gripper 11 can be driven by high-pressure air, with the air circuit controlled by a solenoid valve to achieve rapid locking and unlocking. This method not only simplifies the operation process but also improves safety and reliability. The insertion post 21 can be made of high-strength metal materials, such as stainless steel or titanium alloy, to ensure that it will not deform or be damaged during long-term use.
[0014] By introducing pneumatic grippers 11 and insert pins 21, rapid fixing and disassembly between the positioning table 2 and the fixed table 1 are achieved. This method not only simplifies the operation steps and shortens mold change time, but also improves the safety and reliability of the operation. Especially for large-scale production and automated production lines, this design can significantly improve production efficiency and management level.
[0015] To further improve the ease of installation and disassembly of the positioning platform 2, a lifting ring 22 can be installed on one side of the positioning platform 2. The lifting ring 22 facilitates the lifting of the positioning platform 2, and is especially suitable for large or heavy positioning platforms 2. The lifting ring 22 can be fixed to the positioning platform 2 by welding or threaded connection to ensure its firmness and reliability.
[0016] Reference Figure 3 and Figure 4 The clamping assembly 3 mainly includes baffles 31 disposed on both sides of the positioning platform 2, a positioning plate 32 disposed in the middle of the positioning platform 2, and clamping plates 33 slidably connected to the sides of the positioning plate 32 near the baffles 31, forming a clamping station with the clamping plates 33 and the baffles 31. Sliding grooves 321 are formed on both sides of the positioning plate 32, and the sliding grooves 321 are inclined from the side of the positioning plate 32 away from the positioning platform 2 towards the side of the positioning platform 2, allowing the clamping plate 33 to gradually approach the valve body during sliding, thus achieving a more stable clamping effect. A sliding block 34 is fixedly connected to the clamping plate 33, and the sliding block 34 is inclined from the side of the clamping plate 33 away from the positioning platform 2 towards the side away from the positioning plate 32, forming an inclined surface. When the clamping plate 33 is slid downwards, the inclined surface on the sliding block 34 slides within the inclined surface of the sliding groove 321, making the clamping plate 33 slide more tightly against the valve body as it slides towards the positioning platform 2, resulting in a more stable connection to the valve body.
[0017] In addition, to further improve the reliability and safety of clamping, anti-slip pads can be provided on the contact surfaces of clamping plate 33 and baffle 31. The anti-slip pads can be made of rubber or silicone material to enhance friction and prevent the valve body from sliding or loosening during processing.
[0018] A buffer assembly 12 is provided at the bottom of the fixed platform 1. The buffer assembly 12 includes multiple buffer springs 121. The ends of the buffer springs 121 away from the fixed platform 1 are all fixedly connected to a buffer plate 122, which is used to abut against the end of the positioning platform 2. When the hoisted positioning platform 2 is installed on the fixed platform 1, the end of the positioning platform 2 impacts the buffer plate 122. The tension of the buffer springs 121 buffers the impact of the buffer plate 122, thereby preventing direct impact between the end of the positioning platform 2 and the fixed platform 1 and reducing wear between the positioning platform 2 and the fixed platform 1.
[0019] To further improve the cushioning effect, a cushioning rubber pad 13 can be installed on the side wall of the fixed platform 1. The cushioning rubber pad 13 can be pasted or embedded in the side wall of the fixed platform 1, providing a double cushioning effect. The selection of the cushioning rubber pad 13 should take into account its hardness and elasticity to ensure that it can effectively absorb the impact without affecting the precise installation of the positioning platform 2.
[0020] In addition, anti-collision posts 14 are installed at the four corners of the side wall of the fixed platform 1. The anti-collision posts 14 can reduce the impact between the hoisted positioning platform 2 and the fixed platform 1, thereby reducing the wear between the positioning platform 2 and the fixed platform 1.
[0021] The bollard 14 can be made of soft plastic or rubber materials, which have excellent cushioning and resilience. The height and diameter of the bollard 14 can be adjusted according to actual application requirements to ensure optimal protection. Furthermore, the bollard 14 can be installed using adhesive, screw fixing, or an embedded design to ensure its secure and reliable installation.
[0022] The implementation principle of this embodiment is as follows: By designing the fixed platform 1, it can simultaneously accommodate multiple positioning platforms 2, and each positioning platform 2 can clamp two valve bodies, realizing simultaneous processing at multiple workstations. This design not only reduces material changeover time and operational complexity but also significantly improves production efficiency. Especially for batch production environments, this highly compatible fixture can effectively increase the overall capacity of the production line. In addition, through the modular design of the positioning platforms 2, different positioning platforms 2 can be flexibly selected and replaced according to actual needs, further enhancing the applicability and flexibility of the fixture.
[0023] By installing buffer components 12 and buffer rubber pads 13 on the bottom and side walls of the fixed platform 1, the impact force on the positioning platform 2 during installation and disassembly is effectively reduced, thus minimizing wear and damage caused by impact. This is especially important for production equipment that operates for extended periods, as it can extend the equipment's service life, reduce maintenance costs, and improve the stability and reliability of the production system.
[0024] By installing anti-collision posts 14 at the four corners of the fixed platform 1, a comprehensive protective barrier is formed, effectively preventing the positioning platform 2 from colliding with other objects during installation and transportation, and reducing unnecessary wear and damage. This design is particularly suitable for working environments with limited space or frequent operations, and can significantly improve the safety and service life of the equipment. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
