[0022] Example
[0023] A fixing device for valve processing includes a processing table 2. The processing table 2 has a storage area 7 for placing valves in the middle. The storage area 7 has movable fixing mechanisms and a driving component for driving the movable fixing mechanisms to move relative to each other. The driving component drives the two movable fixing mechanisms to move closer to each other to wrap and press the valves together.
[0024] In this embodiment, as Figure 1 As shown, the processing table 2 serves as the foundation of the entire device, providing stable support for other components. The processing table 2 is installed on a hard surface or other rigid frame. The storage area 7 is located in the middle of the processing table 2 and is specifically used to place valves for convenient processing operations. The movable fixing mechanisms are symmetrically arranged on both sides of the storage area 7. Driven by the drive component, they can move flexibly laterally to adapt to valves of different sizes and shapes. When the drive component is working, the two movable fixing mechanisms will move closer to each other and wrap around and press the valves to fix them. This fixing method changes from the existing point contact fixing method to a surface contact fixing method, resulting in better fixing effect. The valves are less likely to move during processing, which can effectively prevent the valves from moving or shaking during processing, ensuring processing accuracy and efficiency.
[0025] Optionally, the movable fixing mechanism includes a U-shaped fixing plate 4 and an elastic body 6. The elastic body 6 is fixed to the open side of the fixing plate 4, and a sealed receiving cavity is formed between the elastic body 6 and the fixing plate 4. The receiving cavity is filled with a liquid electromorph 8. The electromorph 8 has a wire 5 inside, and the two ends of the wire 5 are located outside the fixing plate 4. The fixing plate 4 is slidably connected to the processing table 2, and the driving component can drive the fixing plate 4 to move along the length direction of the processing table 2.
[0026] Specifically, such as Figure 2 and Figure 3 As shown, the U-shaped fixing plate 4 serves as the foundation of the fixing mechanism, providing sufficient strength and stability. At the same time, its open design allows the valve to be easily placed into the fixing mechanism. Furthermore, the elastic body 6 is fixed to the open side of the fixing plate 4, forming a sealed receiving cavity between it and the fixing plate 4. This receiving cavity not only protects the internal current deformable body, but also, through the deformation capability of the elastic body 6, can adapt to valves of different sizes, increasing the flexibility and adaptability of the fixing mechanism. When the irregular valve is placed in the storage area 7, the drive assembly drives the fixing plates 4 of the two movable fixing mechanisms to move closer together, so that the elastic body 6 contacts and squeezes the valve sidewall. The elastic body 6 deforms under the pressure and fits to wrap the valve. At the same time, the liquid current variant 8 in the cavity deforms under the action of the elastic body 6. After the elastic body 6 wraps the valve in place, the wire 5 is energized. Under the action of the electric field, the current variant 8 will change from liquid to solid within a few milliseconds, thereby clamping and fixing the irregular valve. The fixing mechanism formed by this method has a more stable clamping and fixing effect on the valve, making it less likely to be displaced during the valve processing, effectively improving the processing quality and efficiency of the valve.
[0027] Optionally, the elastomer 6 is a film structure made of rubber, and the thickness of the elastomer 6 is 5-10 mm.
[0028] Specifically, firstly, rubber is used as the elastomer 6 because rubber has excellent elasticity and wear resistance, allowing it to adapt well to changes in valve shape while maintaining a long service life. The elasticity of rubber allows it to deform under external force but quickly return to its original shape after the force is removed. This characteristic is ideal for fixing valves and other workpieces that require flexible adaptation to different shapes and sizes. Secondly, the membrane structure design allows the elastomer 6 to be evenly distributed on the open side of the fixing plate 4, forming a continuous, seamless sealed cavity. This structure not only enhances the overall stability of the fixing mechanism but also effectively prevents leakage or overflow of the current-deformable element during operation, ensuring the safety and reliability of the fixing mechanism. Furthermore, the choice of an elastomer 6 thickness of 5-10mm ensures sufficient elastic deformation capacity to adapt to valves of different sizes while avoiding problems such as excessive rigidity due to excessive thickness or insufficient strength due to excessive thinness. At the same time, this thickness range also provides high durability and stability, enabling it to maintain good working condition for extended periods. In summary, using a rubber membrane structure as the elastomer 6 and controlling its thickness within the range of 5-10mm is a very reasonable and effective design choice. This design can fully utilize the advantages of the elastomer 6, improve the stability and reliability of the fixing mechanism, and provide strong support for valve processing.
[0029] Optionally, the current variant 8 is lime, carbon powder, or gypsum, and the current variant 8 changes from a liquid state to a solid state after the wire 5 is energized.
[0030] Optionally, the bottom surface of the fixed plate 4 is provided with a slider 10, and the top surface of the processing table 2 is provided with a recessed groove 3 adapted to the slider 10. The slider 10 is located in the groove 3, and the groove 3 is located on the side of the storage area 7. The driving component drives the slider 10 to move laterally, thereby driving the fixed plate 4 to move along the length direction of the processing table 2.
[0031] Optionally, the drive assembly includes a drive motor 1 and a lead screw 9. The lead screw 9 has an external thread on its side wall. Both ends of the lead screw 9 are rotatably connected to the two side walls of the slide groove 3, respectively. The slider 10 passes through the lead screw 9 and is threadedly connected to the lead screw 9. One end of the lead screw 9 extends to the outside of the processing table 2 and is connected to the output end of the drive motor 1.
[0032] Optionally, the side wall of the slider 10 is provided with a through hole for the lead screw 9 to pass through, and the inner wall of the through hole is provided with an internal thread adapted to the external thread.
[0033] Specifically, such as Figure 2 and Figure 3As shown, the slider 10 on the bottom surface of the fixed plate 4 and the recessed groove 3 on the top surface of the processing table 2, which is adapted to the slider 10, constitute a stable and efficient sliding mechanism. The groove 3 does not penetrate the processing table 2 laterally, ensuring that the fixed plate 4 can move smoothly on the processing table 2, and making the entire movement process more precise and controllable. The groove 3 is located on the side of the placement area 7. This layout ensures that the fixed plate 4 has sufficient space to move, while avoiding interference with the placement area 7, ensuring the smooth progress of the valve processing. The drive assembly adopts a combination of a drive motor 1 and a lead screw 9. The external thread of the lead screw 9 cooperates with the internal thread in the through hole of the slider 10 to realize the conversion of the rotational motion of the motor into the linear motion of the slider 10. This drive method is not only simple in structure and easy to maintain, but also has the characteristics of high precision and high efficiency. By controlling the forward and reverse rotation of the drive motor 1, the fixed plate 4 can be easily moved closer and further away, thereby realizing the rapid fixing and release of the valve. Furthermore, this driving method also boasts good stability and reliability. Due to the self-locking function of the threaded connection between the lead screw 9 and the slider 10, the fixing plate 4 remains in its current position even when the motor stops working, preventing valve loosening or displacement due to unforeseen circumstances. Simultaneously, the through-hole design of the slider 10 increases the contact area between it and the lead screw 9, improving the stability and durability of the connection. In summary, the design of this movable fixing mechanism and its driving components fully considers the actual needs and operational convenience of valve processing. Through ingenious structural design and reasonable material selection, it achieves rapid, stable, and precise valve fixing, providing strong support and guarantee for valve processing.
[0034] The working principle of this utility model is as follows: The valve to be processed is placed in the storage area 7, and then the drive motors 1 on both sides are started, driving the lead screw 9 to rotate. Under the limiting action of the slide groove 3, the slider 10 is driven by the rotation of the lead screw 9 to move the slider 10 along the slide groove 3 and the lead screw 9 axially, so that the two U-shaped fixing plates 4 are relatively close to each other, so that the elastic body 6 contacts and squeezes the valve side wall. The elastic body 6 is deformed under the compression and fits to wrap the valve. At the same time, the liquid current variant 8 in the cavity is deformed under the action of the elastic body 6. After the elastic body 6 wraps the valve in place, the wire 5 is energized. Under the action of the electric field, the current variant 8 will change from liquid to solid within a few milliseconds, thereby clamping and fixing the irregular valve. The fixing mechanism formed by this method has a more stable clamping and fixing effect on the valve, making it less likely to be displaced during the valve processing, effectively improving the processing quality and processing efficiency of the valve.
[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
