Description

Technical Field

[0001] This application relates to the field of machining, and in particular to a multi-workpiece valve body fixture. Background Technology

[0002] In the field of machining, the valve body, as a core component of fluid control equipment, directly affects the valve's sealing performance and service life due to its machining accuracy. With the continuous improvement of industrial automation, machining technology has developed rapidly, especially in improving production efficiency and machining accuracy.

[0003] While traditional single-piece clamping methods can meet the needs of small-scale production, their shortcomings are becoming increasingly apparent in modern large-scale manufacturing, necessitating the development of more efficient and reliable clamping technologies to adapt to market demands. Currently, to address the fixation issues during valve body machining, the industry commonly employs three-jaw chucks or specialized clamps for single-piece clamping. Specifically, common methods include using manual clamping devices to fix workpieces one by one, or using hydraulic clamps to achieve rapid clamping of individual workpieces. Additionally, some companies have attempted to utilize magnetic or pneumatic clamps to improve clamping efficiency. However, these methods are mostly based on single-piece operation, which, while ensuring machining accuracy to a certain extent, struggles to meet the demands of mass production. The main drawback of these traditional clamping methods is that only one workpiece can be fixed at a time, resulting in low machining efficiency and an inability to effectively cope with the high-paced requirements of large-scale production. Especially in applications involving simultaneous machining of multiple workpieces, existing clamping devices struggle to achieve efficient and stable batch clamping, becoming a key bottleneck restricting improvements in production efficiency. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a multi-workpiece valve body fixture. The multi-workpiece valve body fixture includes a positioning seat, which is a polygonal prism. Each side wall of the positioning seat is detachably connected to a mounting plate. The mounting plate has multiple mounting positions, and each mounting position contains a clamping assembly for holding the valve body. By adopting the above technical solution, the user first fixes the valve body to the mounting plate using the clamping assembly, and then the mounting plate is installed on the positioning seat. This allows multiple workpieces to be fixed at once, facilitating the simultaneous processing of multiple valve bodies, replacing the traditional method of clamping only one valve body at a time, and improving work efficiency. Preferably, the valve body includes a rod, on which a prismatic snap-fit ​​member is fixedly connected. The clamping assembly includes an insertion hole on the mounting plate, and baffles are fixedly connected to both sides of the insertion hole on the mounting plate. A slot is provided at the adjacent end of the baffle for limiting and clamping the snap-fit ​​member. By adopting the above technical solution, when using the device, the user can offset the position of the snap-fit ​​component from the baffle, insert the end of the rod into the insertion hole, rotate the rod, and make the snap-fit ​​component on the rod engage in the slot of the baffle to fix the rod body valve body. When disassembling, rotate the rod until the snap-fit ​​component separates from the baffle to remove the valve body, which facilitates the disassembly and installation of the valve body.

[0005] Preferably, the positioning seat has at least three sidewalls. By adopting the above technical solution, when the user uses the positioning seat, the more sidewalls it has, the more positioning plates can be installed, and the more valve bodies can be clamped and fixed at once.

[0006] Preferably, two mounting posts are fixedly connected to one side of the positioning plate clamping assembly. A fixing plate is provided on the side wall of the positioning seat, and the fixing plate has through holes for the mounting posts to pass through. The fixing plate is also provided with a locking mechanism for automatically clamping the mounting posts. By adopting the above technical solution, when the user fixes the mounting plate on the positioning seat, the mounting posts are inserted into the through holes of the fixing plate, and the locking mechanism clamps the mounting posts, thus fixing the mounting plate on the positioning seat.

[0007] Preferably, the positioning plate has a limiting groove, within which a disc is rotatably connected. The center of the disc has a through groove for the insertion pin to pass through. Multiple limiting grooves are formed on the disc, and a positioning pin is slidably connected within each limiting groove. A clamping plate is fixedly connected to the end of each positioning pin, and a drive assembly for rotating the disc is connected to the fixed plate. By adopting the above technical solution, when the user uses the device, the drive assembly drives the disc to rotate, causing the disc to slide the positioning pin within the limiting groove. The positioning pin then drives the clamping plate to move towards the center of the disc, thus clamping and fixing the positioning pin.

[0008] Preferably, the end of the clamping plate has an arc-shaped surface. By adopting the above technical solution, when the user uses the clamping plate, the arc-shaped end increases the contact area between the clamping plate and the positioning post, resulting in more stable clamping of the positioning post.

[0009] Preferably, the driving assembly includes a driving cylinder fixedly connected to a fixed plate. A connecting rod is fixedly connected to the end of the piston rod of the driving cylinder, and racks are fixedly connected to both ends of the connecting rod. A positioning disc is fixedly connected to the disc, and an external gear ring is fixedly connected to the edge of the disc. The external gear ring meshes with the rack. By adopting the above technical solution, when the user uses the device, the piston rod of the driving cylinder extends, pushing the connecting rod to slide. The connecting rod drives the rack to move, the rack drives the disc to rotate, and the disc drives the positioning pin to slide within the limiting groove. The positioning pin drives the clamping plate to move towards the center of the disc, so that the clamping plate clamps the positioning pin and achieves fixation.

[0010] Preferably, a locking cylinder is fixedly connected to the fixing plate, and two slots are provided on the connecting rod. The locking cylinder is inserted into the slots to fix the connecting rod. By adopting the above technical solution, when the user uses the device, after the drive cylinder drives the gear ring to rotate, causing the clamping plate to clamp and fix the positioning post, the piston rod of the locking cylinder is inserted into the slot to lock the rack, thereby locking the clamping plate.

[0018] The following will be combined with the appendix Figure 1-6This application provides a clear and complete description of the technical solutions in the embodiments of this utility model. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can combine the embodiments of this utility model to obtain other embodiments without creative labor, and these embodiments are also within the protection scope of this utility model. The inventors of this application have discovered that in the field of machining, the valve body, as the core component of fluid control equipment, directly affects the sealing performance and service life of the valve in terms of machining accuracy. With the continuous improvement of industrial automation, although the traditional single-piece clamping method can meet the needs of small-scale production, it has gradually revealed its shortcomings in modern large-scale production, and there is an urgent need to develop more efficient and reliable clamping technology to meet market demands. To this end, this application mainly adopts the following scheme to achieve the effect of simultaneous clamping and fixing of multiple workpieces, thereby significantly improving machining efficiency. Embodiment 1 A valve body includes a rod 11, on which a snap-fit ​​member 12 is fixedly connected. The snap-fit ​​member 12 is arranged in a rhomboid shape. The rod 11 is provided with protruding posts 13, and three protruding posts 13 are respectively provided, two of which are located on one side and one of which is located on the opposite side of the rod 11. Example 2: A multi-workpiece valve body fixture provided in this application includes a positioning seat 2, which is a polygonal prism. Each side wall of the positioning seat 2 is detachably connected to a mounting plate 3. The mounting plate 3 has multiple mounting positions, and each mounting position contains a clamping assembly 31 for clamping a valve body 1. This structural design allows multiple workpieces to be fixed at once, facilitating the simultaneous processing of multiple valve bodies 1, replacing the traditional method of clamping only one valve body 1 at a time, and significantly improving work efficiency. Specifically, the positioning seat 2 is a polygonal prism structure, which can be a regular square prism, a regular hexagonal prism, or other polygonal prisms. The more sides the prism has, the more mounting plates 3 can be installed, thus increasing the number of valve bodies 1 that can be clamped and fixed at once. For example, when the positioning seat 2 is a regular hexagonal prism, six mounting plates 3 can be installed; when the positioning seat 2 is a regular octagonal prism, eight mounting plates 3 can be installed. Mounting plate 3 is fixed to the side wall of positioning seat 2 by bolts or other detachable connection methods. This design allows mounting plate 3 to be quickly replaced or adjusted as needed, making it easy to adapt to the processing requirements of valve body 1 of different specifications.

[0019] The clamping assembly 31 includes a plug hole 311, a baffle 312, and a slot 313. The plug hole 311 is formed on the mounting plate 3 to accommodate the rod 11 of the valve body 1. The baffle 312 is fixedly connected to both sides of the plug hole 311, and a slot 313 is formed at one end of the baffle 312. The slot 313 is used to limit and clamp the snap-fit ​​member 12 on the valve body 1. Specifically, a diamond-shaped snap-fit ​​member 12 is fixedly connected to the rod 11 of the valve body 1. When in use, the snap-fit ​​member 12 is positioned opposite to the baffle 312, and the end of the rod 11 is inserted into the plug hole 311. The rod 11 is rotated so that the snap-fit ​​member 12 on the rod 11 is engaged in the slot 313 of the baffle 312, thus fixing the valve body 1. When disassembling, the rod 11 is rotated until the snap-fit ​​member 12 separates from the baffle 312, thus removing the valve body 1. This design is not only easy to operate, but also enables quick clamping and disassembly, further improving processing efficiency.

[0020] In addition, to enhance the stability of the clamping assembly 31, anti-slip textures or rubber gaskets can be provided on the inner wall of the insertion hole 311 to increase friction and prevent the valve body 1 from loosening during processing. Meanwhile, the baffle 312 can be made of high-strength steel or aluminum alloy to ensure sufficient strength and durability. The slot 313 can be designed in a trapezoidal or rectangular shape to match the snap-fit ​​component 12, ensuring that the snap-fit ​​component 12 can be securely embedded within it. Two mounting posts 32 are fixedly connected to one side of the mounting plate 3 away from the clamping assembly 31. A fixing plate 21 is provided on the side wall of the positioning seat 2, with through holes 22 for the mounting posts 32 to pass through. A locking mechanism 23 is provided on the fixing plate 21 to automatically clamp the mounting posts 32. With this design, when the user fixes the mounting plate 3 onto the positioning seat 2, the mounting post 32 is inserted into the through hole 22 of the fixing plate 21, and the mounting post 32 is clamped by the locking mechanism 23, thus firmly fixing the mounting plate 3 onto the positioning seat 2. The fixing plate 21 has a receiving groove 24. The locking mechanism 23 includes a disc 231 rotatably connected within the receiving groove 24. The center of the disc 231 has a through groove 2311 for the insertion post to pass through. The disc 231 has multiple limiting grooves 232, within which a positioning post 233 is slidably connected. A clamping plate 234 is fixedly connected to the end of the positioning post 233, and the clamping plate 234 abuts against the outer wall of the mounting post 32. The multiple clamping plates 234 clamp and fix the mounting post 32. Specifically, the limiting groove 232 can be designed to be arc-shaped, and its depth should be sufficient to accommodate the sliding of the positioning post 233. The disc 231 can be made of high-strength steel or aluminum alloy, and its surface can be provided with anti-slip textures or toothed structures to increase friction. The positioning post 233 can be designed in a cylindrical or square shape, and its material can be high-strength steel or aluminum alloy. The end of the clamping plate 234 has an arc-shaped surface, which can increase the contact area between the clamping plate 234 and the positioning post 233, making the clamping of the positioning post 233 more stable. The driving cylinder 235 on the fixed plate 21 has a connecting rod 236 fixedly connected to the piston rod end of the driving cylinder 235. The two ends of the connecting rod 236 are fixedly connected to the rack 237. The positioning disc 238 is fixedly connected to the disc 231, and the edge of the positioning disc is fixedly connected to the external gear ring 2381, which meshes with the rack 237.

[0021] A locking cylinder 239 is fixedly connected to the fixed plate 21. Two slots 2361 are provided on the connecting rod 236, and the locking cylinder 239 is inserted into the slots 2361 to fix the connecting rod 236. With this design, when the user uses the device, the drive cylinder 235 drives the gear ring to rotate, causing the clamping plate 234 to clamp and fix the positioning post 233. Then, the piston rod of the locking cylinder 239 is inserted into the slots 2361 to lock the rack 237, thereby locking the clamping plate 234. The implementation principle of this embodiment is as follows: by adopting a multi-prism structure positioning seat 2 and a mounting plate 3 with multiple mounting positions, simultaneous clamping and fixing of multiple workpieces is achieved, significantly improving processing efficiency compared to the traditional single-piece clamping method. The design of the clamping assembly 31 makes the clamping and disassembly process of the valve body 1 more convenient, while ensuring clamping stability and avoiding errors caused by insecure clamping during processing. This design not only meets the high-paced requirements of modern large-scale production, but also effectively improves processing precision and product quality.

[0022] By setting a mounting post 32 on one side of the clamping assembly 31 on the mounting plate 3, and setting a fixing plate 21 and a locking mechanism 23 on the side wall of the positioning seat 2, the mounting plate 3 can be quickly fixed and disassembled. This design not only simplifies the operation process, but also improves the fixing stability of the mounting plate 3, avoiding machining errors caused by the loosening of the mounting plate 3. At the same time, the selection of multiple locking mechanisms 23 allows users to flexibly choose the most suitable solution according to actual needs, further improving the applicability and reliability of the fixture. By setting a locking cylinder 239 on the fixing plate 21 and opening a slot 2361 on the connecting rod 236, double locking and fixing of the clamping plate 234 is achieved. This design not only further improves the clamping stability, but also avoids machining errors caused by insecure clamping. At the same time, the operation of the locking cylinder 239 is simple and reliable, and users can flexibly choose the most suitable locking method according to actual needs, further improving the applicability and reliability of the fixture.

[0023] 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 in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
