Description

Technical Field

[0001] This application relates to the field of valve manufacturing technology, and in particular to a machining tooling for valve manufacturing. Background Technology

[0002] With the increasing demands for equipment performance in high-end fields such as semiconductors and aerospace, the need for high-precision valves is becoming increasingly urgent. These valves need to meet the requirements of sealing performance, corrosion resistance, and lightweight design under extreme operating conditions. For example, ultra-clean valves in semiconductor manufacturing need to achieve micron-level sealing in a dust-free environment, while the aerospace field requires valves to remain stable under high pressure, high temperature, and severe vibration. These scenarios pose challenges to the valve's manufacturing process, material compatibility, geometric accuracy, and long-term stability.

[0003] In related technologies, traditional machining fixtures can only position specific valves, resulting in poor adaptability. When faced with a wide variety of valves with different specifications, it is necessary to redesign and replace the corresponding fixtures every time a new valve model is changed. This not only consumes a lot of time and costs, but also seriously affects production efficiency, so it needs to be improved. Utility Model Content

[0004] To address the problem of poor adaptability of traditional machining tooling, this application provides a machining tooling for valve production.

[0005] The technical solution for a valve manufacturing tooling provided in this application is as follows:

[0006] A machining fixture for valve production includes a fixture plate with a positioning platform for placing the valve. The fixture plate also has a top clamping mechanism, comprising a pressure plate body, a main pressure block, a secondary pressure block, and an adjusting bolt. The pressure plate body is movably mounted on the fixture plate. The main pressure block is connected to the pressure plate body and has an adjusting assembly for adjusting the vertical height of the main pressure block. The secondary pressure block is located on the side of the main pressure block away from the pressure plate body. The adjusting bolt connects the main pressure block and the secondary pressure block. Both the main and secondary pressure blocks have arc-shaped grooves on their opposite surfaces for clamping the valve. The fixture plate also includes a lateral pressing mechanism and a lateral clamping mechanism.

[0007] Traditional machining fixtures can only position specific valves and have poor adaptability. When faced with a wide variety of valves with different specifications, it is necessary to redesign and replace the corresponding fixtures every time a new valve model is changed. This not only consumes a lot of time and costs, but also seriously affects production efficiency. By adopting the above technical solution, including a fixture plate, the positioning platform is installed on the fixture plate. At the same time, the top clamping mechanism, the side pressing mechanism, and the side clamping mechanism are all installed on the fixture plate. The top clamping mechanism includes a pressure plate body, a main pressure block, a secondary pressure block, and adjusting bolts.

[0008] When positioning the valve, place the valve to be processed stably on the positioning platform to initially determine the approximate position of the valve on the positioning platform. The operator first loosens the clamping screw, releases the fixation of the lateral clamping mechanism, and pushes the entire lateral clamping mechanism to gradually approach the valve end face. According to the actual height of the valve and the clamping position, clamp the valve side. Then move the pressure plate body of the top clamping mechanism and move it to a suitable position above the valve by adjusting the components. The top of the valve is located in the area of ​​the arc groove of the main pressure block and the auxiliary pressure block. Rotate the adjusting bolt to apply the required clamping force to the top of the valve. Finally, move the lateral pressing mechanisms on both sides to ensure that they can gently press against the other side of the valve to provide auxiliary support. After completing the above positioning and clamping steps, the valve can be processed accordingly.

[0009] By incorporating tooling plates, positioning platforms, and top clamping mechanisms, the system can quickly adapt to valves of different specifications without frequent tooling changes. This improves the versatility and utilization of the tooling, effectively solving the problem of poor adaptability of traditional tooling. It significantly saves time and economic costs associated with tooling replacement and substantially enhances production efficiency.

[0010] Optionally, the adjustment assembly includes an adjustment slider and a fastener. The pressure plate body has an adjustment groove along the height direction. The adjustment slider is slidably connected in the adjustment groove. The main pressure block is fixedly connected to the adjustment slider. The fastener is used to lock the position of the adjustment slider in the adjustment groove.

[0011] By adopting the above technical solution, the adjustment component includes an adjustment slider and fasteners; when it is necessary to adjust the vertical height of the main pressure block, use a suitable tool to gradually loosen the locking effect of the fasteners on the adjustment slider, gently push the adjustment slider by hand to make it slide up and down along the adjustment groove, adjust the main pressure block on the adjustment slider to a suitable height position according to the actual height of the valve and the processing requirements, and use a tool to tighten the fasteners so that the adjustment slider is firmly locked in the adjustment groove;

[0012] By adjusting the component settings, valves of different specifications can be quickly adapted without complicated operations or additional tooling changes, greatly saving time and costs. Precise height adjustment ensures the stability and accuracy of the valve during processing, effectively improving processing quality.

[0013] Optionally, the lateral clamping mechanism consists of two sets, which are symmetrically arranged on the tooling plate. Each set of the lateral clamping mechanism includes a clamping plate, a guide rod, and a clamping screw. The guide rod is vertically connected to the tooling plate, the clamping plate is connected to the top of the guide rod, one end of the clamping screw passes through the clamping plate and is threadedly connected to the clamping plate, and the other end of the clamping screw presses against the tooling plate.

[0014] By adopting the above technical solution, there are two sets of lateral clamping mechanisms, which are symmetrically arranged on the tooling plate. Each lateral clamping mechanism includes a clamping plate, a guide rod, and a clamping screw. Through the setting of the lateral clamping mechanism, the valve can be laterally clamped. The clamping force of the clamping plate is precisely controlled through the threaded transmission to achieve stable and reliable lateral clamping.

[0015] Optionally, the bottom end of the clamping screw is provided with a pressing knob, which contacts the surface of the tooling plate.

[0016] By adopting the above technical solution, the pressure knob is installed at the bottom of the clamping screw. By setting the pressure knob, the contact area between the clamping screw and the tooling plate is increased, which can effectively disperse the pressure and avoid damage to the tooling plate caused by excessive local pressure. At the same time, the pressure knob provides a comfortable force application point for the operator, making it convenient for personnel to operate.

[0017] Optionally, the lateral pressing mechanism consists of two sets, which are symmetrically arranged on the tooling plate, and the arrangement directions of the two sets of lateral pressing mechanisms are staggered with the arrangement directions of the two sets of lateral clamping mechanisms.

[0018] By adopting the above technical solution, there are two sets of lateral pressing mechanisms. The two sets of lateral pressing mechanisms are symmetrically arranged on the tooling plate, and the arrangement direction of the two sets of lateral pressing mechanisms is staggered with the arrangement direction of the two sets of lateral clamping mechanisms. By setting the number and arrangement of the lateral pressing mechanisms, the staggered distribution can apply force to the valve from multiple different directions, effectively preventing the valve from shifting or shaking during processing, and improving the stability and accuracy of processing.

[0019] Optionally, the lateral pressure mechanism includes a lateral pressure support and a pressure column. The lateral pressure support is slidably arranged on the tooling plate, and the pressure column is connected to the lateral pressure support and presses against the outer wall of the valve.

[0020] By adopting the above technical solution, the lateral pressure-blocking mechanism includes a lateral pressure support and a pressure-blocking column. With the setting of the lateral pressure-blocking mechanism, the position of the pressure-blocking column can be quickly adjusted according to the actual size of the valve, so that it accurately presses against the outer wall of the valve, providing stable and reliable lateral pressure, effectively preventing the valve from lateral shaking or displacement during processing, and ensuring the stability and accuracy of processing.

[0021] Optionally, the bottom of the guide rod, the side pressure support, and the pressure plate body are all provided with T-shaped blocks, and the tooling plate is provided with a number of T-shaped grooves for sliding the T-shaped blocks. Each of the T-shaped blocks is provided with a fastening bolt for fixing.

[0022] By adopting the above technical solution, T-blocks are installed at the bottom of the guide rod, side pressure support, and pressure plate body. T-slots are opened on the tooling plate, and fastening bolts for fixing are provided on the T-blocks. Through the setting of T-blocks, T-slots and fastening bolts, each component can slide smoothly and stably on the tooling plate to achieve position adjustment. It can quickly adapt to valves of different sizes and shapes, and improve the versatility and flexibility of the tooling.

[0023] Optionally, the positioning platform is provided with a number of positioning posts for limiting the position of the valve.

[0024] By adopting the above technical solution, the positioning column is installed on the positioning platform to ensure that the corresponding reference hole / face of the valve makes precise contact with the positioning column; through the setting of the positioning column, the positioning column can quickly and accurately limit the position of the valve, ensuring that the valve always maintains a stable and correct posture during the processing, effectively avoiding processing errors caused by position deviation, and greatly improving processing accuracy and product quality.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The tooling plate, positioning platform, and top clamping mechanism help to quickly adapt to valves of different specifications without frequent tooling changes, improving the versatility and utilization of the tooling. This effectively solves the problem of poor adaptability of traditional tooling, significantly saves time and economic costs caused by tooling changes, and significantly improves production efficiency.

[0027] 2. By adjusting the component settings, it can quickly adapt to valves of different specifications without complicated operations or additional tooling replacements, greatly saving time and costs. Precise height adjustment ensures the stability and accuracy of the valve during processing, effectively improving processing quality.

[0028] 3. By setting up a lateral pressure-relief mechanism, the position of the pressure-relief column can be quickly adjusted according to the actual size of the valve, so that it accurately presses against the outer wall of the valve, providing stable and reliable lateral pressure, effectively preventing the valve from lateral shaking or displacement during processing, and ensuring the stability and accuracy of processing.

[0033] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0034] This application discloses a machining fixture for valve manufacturing. (Refer to...) Figure 1 The valve manufacturing fixture includes a fixture plate 1, on which a positioning platform 2 is mounted. In this embodiment, the positioning platform 2 is used to place the valve. Several positioning posts 13 are mounted on the positioning platform 2. Preferably, there are three positioning posts 13 to ensure that the corresponding reference hole / face of the valve is in precise contact with the positioning post 13. The positioning post 13 can quickly and accurately limit the position of the valve, ensuring that the valve always maintains a stable and correct posture during the processing, effectively avoiding processing errors caused by position deviation, and greatly improving processing accuracy and product quality.

[0035] Reference Figure 1 and Figure 2 The tooling plate 1 is equipped with a top pressing mechanism 3, a side pressing mechanism 6, and a side pressing mechanism 7. In this embodiment, there are two sets of side pressing mechanisms 7, which are symmetrically arranged on the tooling plate 1. Each set of side pressing mechanisms 7 includes a pressing plate 71, a guide rod 72, and a pressing screw 73. The guide rod 72 is vertically installed on the tooling plate 1. In this embodiment, the guide rod 72 can slide on the tooling plate 1, and the pressing plate 71 is installed on the top of the guide rod 72.

[0036] Reference Figure 1 and Figure 2 One end of the clamping screw 73 passes through the clamping plate 71 and is threadedly connected to the clamping plate 71. The other end of the clamping screw 73 is fixedly mounted with a pressure knob 9, which contacts the surface of the tooling plate 1. The lateral clamping mechanism 7 can laterally clamp the valve. It precisely controls the clamping force of the clamping plate 71 through threaded transmission to achieve stable and reliable lateral clamping. At the same time, the pressure knob 9 increases the contact area between the clamping screw 73 and the tooling plate 1, providing a comfortable force application point for the operator and facilitating operation.

[0037] Reference Figure 1The top pressing mechanism 3 includes a pressure plate body 31, a main pressure block 32, a secondary pressure block 33, and an adjusting bolt 34. The pressure plate body 31 is movably arranged on the tooling plate 1. The main pressure block 32 is arranged on one side of the pressure plate body 31. An adjusting component 4 is installed on the pressure plate body 31. The adjusting component 4 is used to adjust the vertical height of the main pressure block 32. The adjusting component 4 includes an adjusting slider 41 and a fastener 42. The pressure plate body 31 has an adjusting groove 8 along the height direction. The adjusting slider 41 is slidably connected in the adjusting groove 8. At the same time, the main pressure block 32 is fixedly connected to the adjusting slider 41. The fastener 42 is installed on the adjusting slider 41 and can achieve abutment operation with the tooling plate 1. The fastener 42 can be a bolt. The fastener 42 is used to lock the position of the adjusting slider 41 in the adjusting groove 8.

[0038] Reference Figure 1 The auxiliary pressure block 33 is arranged on the side of the main pressure block 32 away from the pressure plate body 31. The adjusting bolt 34 is connected between the main pressure block 32 and the auxiliary pressure block 33. In this embodiment, the adjusting bolt 34 is used to adjust the distance between the main pressure block 32 and the auxiliary pressure block 33. The opposite surfaces of the main pressure block 32 and the auxiliary pressure block 33 are provided with arc-shaped grooves 5 for clamping the valve. The arc-shaped grooves 5 of the main pressure block 32 and the auxiliary pressure block 33 form an area for fixing the valve.

[0039] Reference Figure 1 and Figure 3 In this embodiment, there are two sets of lateral pressing mechanisms 6. The two sets of lateral pressing mechanisms 6 are symmetrically arranged on the tooling plate 1, and the arrangement direction of the two sets of lateral pressing mechanisms 6 is staggered with the arrangement direction of the two sets of lateral pressing mechanisms 7. The staggered distribution can apply force to the valve from multiple different directions, effectively preventing the valve from shifting or shaking during processing, and improving the stability and accuracy of processing.

[0040] Reference Figure 2 and Figure 3 The lateral pressure mechanism 6 includes a lateral pressure support 61 and a pressure column 62. The lateral pressure support 61 is slidably arranged on the tooling plate 1, and the pressure column 62 is connected to the lateral pressure support 61. In this embodiment, the extension distance of the pressure column 62 on the lateral pressure support 61 can be adjusted. The pressure column 62 presses against the outer wall of the valve. The position of the pressure column 62 can be quickly adjusted according to the actual size of the valve so that it accurately presses against the outer wall of the valve, providing stable and reliable lateral pressure, effectively preventing the valve from lateral shaking or displacement during processing, and ensuring the stability and accuracy of processing.

[0041] Reference Figure 2 and Figure 3The guide rod 72, the side pressure support 61, and the pressure plate body 31 are equipped with T-shaped blocks 10 at their bottoms. Several T-shaped grooves 11 are opened on the tooling plate 1. The T-shaped blocks 10 are slidably connected in the corresponding T-shaped grooves 11. The opening direction of the several T-shaped grooves 11 is consistent. In this embodiment, the two side pressure supports 61 can share a single T-shaped groove 11 or be located in different T-shaped grooves 11. A fastening bolt 12 for fixing is installed on any T-shaped block 10. This allows each component to slide smoothly and stably on the tooling plate 1, realize position adjustment, and quickly adapt to valves of different sizes and shapes, improving the versatility and flexibility of the tooling.

[0042] The implementation principle of a valve manufacturing processing fixture in this embodiment is as follows: When positioning the valve, the valve to be processed is placed stably on the positioning platform 2, ensuring that the corresponding reference hole / face of the valve is precisely in contact with the positioning post 13. This initially determines the approximate position of the valve on the positioning platform 2. The operator first loosens the clamping screw 73, releases the fixation of the lateral clamping mechanism 7, and pushes the lateral clamping mechanism 7 as a whole, allowing it to slide smoothly in the T-slot via the T-shaped slider, gradually approaching the valve end face. According to the actual height of the valve and the clamping position, the clamping plate 7 is adjusted appropriately. At a height of 1, rotate the clamping screw 73 to clamp the valve side with the clamping plate 71. Then move the main body 31 of the top clamping mechanism 3 and adjust it to a suitable position above the valve using the adjusting component 4. The top of the valve is located in the area of ​​the arc groove 5 of the main pressure block 32 and the auxiliary pressure block 33. Rotate the adjusting bolt 34 to apply the required clamping force to the top of the valve. Finally, move the lateral pressure-adhesive mechanisms 6 on both sides to ensure that the pressure-adhesive column 62 can gently abut against the other side of the valve to provide auxiliary support. After completing the above positioning and clamping steps, the valve can be subjected to the corresponding process.

[0043] The tooling plate 1, positioning platform 2, and top clamping mechanism 3 are designed to help quickly adapt to valves of different specifications without frequent tooling changes. This improves the versatility and utilization of the tooling, effectively solves the problem of poor adaptability of traditional tooling, significantly saves time and economic costs caused by tooling changes, and significantly improves production efficiency.

[0044] 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.
