Description

Technical Field

[0001] This utility model belongs to the field of regulating valve processing technology, and in particular relates to a tooling for processing the valve body of a regulating valve. Background Technology

[0002] A regulating valve, also known as a control valve, is a final control element in the field of industrial automation process control. It receives control signals from the regulating control unit and uses power to change process parameters such as flow rate, pressure, temperature, and liquid level of the medium. It generally consists of an actuator and a valve body. The valve body is a major component of the valve. After the initial machining, it needs to be precision machined. Flange machining includes end face, stop, outer circle, and chamfer, which must ensure dimensional accuracy and surface finish to guarantee airtightness.

[0003] For example, patent application number CN202222194011.0 describes a special fixture for cutting and grinding regulating valves, belonging to the technical field of casting processing tooling fixtures. It includes a horizontally arranged first positioning base, a second positioning base, and a third positioning base. A first clamping part, a second clamping part, and a third clamping part are detachably installed in the middle of each of the first, second, and third positioning bases. All three positioning bases are mounted on a base via brackets. This invention has the following advantages: It employs three limiting and clamping points, resulting in high overall positioning reliability and simple operation. When matched with existing robotic arm-type casting riser grinding robots or grinding machine tools, it makes grinding regulating valve bodies more efficient and faster, effectively improving production efficiency, and reducing operating costs, significantly reducing the labor intensity of workers.

[0004] Existing technology uses three limiting and clamping points to make grinding the regulating valve body more efficient and faster, but it still has some shortcomings in use: First, the aforementioned existing technology fixes the valve body flange from the inside. When the flange is being processed, too many limiting and clamping parts will hinder the grinding work. At the same time, the grinding debris cannot be processed, which seriously affects the surrounding working environment. Secondly, the existing technology mentioned above cannot adjust the angle of the valve body during processing. In actual processing, workers need to move and grind it, which increases labor intensity and reduces processing speed. In addition, there is no inspection after processing, so the pass rate of processing cannot be guaranteed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention addresses the following technical problems: the current valve body flange fixing mostly adopts an internal clamping structure, which causes the clamping parts and limiting devices to block the processing area during grinding, forming dead angles, affecting the integrity of grinding, and the metal chips generated during processing cannot be collected in real time, and the splashed chips pollute the working environment. Furthermore, the valve body lacks a degree of freedom angle adjustment mechanism during processing, requiring frequent manual adjustment of position or movement of grinding equipment, and making it difficult to control the pass rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling for processing a regulating valve body, comprising a base and a valve body, with two symmetrically arranged clamping boxes slidably mounted on the upper part of the base, a top rod slidably mounted on the bottom of the clamping boxes, a push plate fixedly mounted on the top end of the top rod inside the clamping box, two symmetrically arranged clamping plates slidably mounted on the bottom of the clamping boxes, a connecting rod rotatably mounted between the two ends of the push plate and the top end of the clamping plate, a first damping block fixedly mounted on the upper surface of the connecting rod, a second damping block fixedly mounted on the lower surface of the top of the inner cavity of the clamping box, a spring fixedly mounted between the first damping block and the second damping block, and a dust collection cover fixedly mounted on one side of the clamping box.

[0007] Optionally, anti-slip textures are fixedly installed on the bottom opposing surfaces of the two clamping plates, and a top block is fixedly installed on the bottom end of the top rod.

[0008] Optionally, a fixing flange is fixedly installed on the upper surface of the base.

[0009] Optionally, a base plate is provided below the base, and a servo motor is fixedly installed on the upper surface of the middle part of the base plate. The output end of the servo motor is fixed to the lower surface of the base.

[0010] Optionally, the upper surface of the base plate is provided with an annular rotating groove, and multiple support rods are fixedly installed on the lower surface of the base, with the bottoms of the multiple support rods rotating in conjunction with the interior of the rotating groove.

[0011] Optionally, a cone-shaped sealing plug is slidably mounted on the top of the valve body, and the sealing plug has an air hole inside.

[0012] Optionally, two symmetrically arranged brackets are fixedly installed on the upper surface of the base. The brackets are L-shaped. A first electric push cylinder and a vacuum cleaner are fixedly installed on the horizontal upper surface of the brackets. The clamping box is fixedly installed on the output end of the first electric push cylinder. The suction end of the vacuum cleaner is connected to a telescopic tube, which is connected to the top of the vacuum hood.

[0013] Optionally, a fixing plate is fixedly installed between the two brackets, and a second electric push cylinder is fixedly installed on the upper surface of the fixing plate. The output end of the second electric push cylinder is fixed to the top of the sealing plug.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) This utility model is equipped with a clamping box, top rod, clamping plate, dust suction hood, push plate and connecting rod, etc., which can clamp and fix the valve body from above, and at the same time drive the dust suction hood to move. It can remove the processing debris during the processing of the valve body, protect the surrounding working environment, and can be removed from the processing position after processing without hindering the disassembly of the valve body, thus improving the use effect. (2) This utility model, through the setting of rotating groove and support rod, can rotate the valve body during processing to adjust the processing angle, thereby improving the processing accuracy and thus improving the use effect. In addition, through the setting of sealing plug, air hole and air pump, the valve body after processing can be sealed and tested, thereby improving the product qualification rate.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Example 1: refer to Figure 1 A tooling for machining the body of a regulating valve includes a base 10 and a valve body 14. A fixing seat is provided at the bottom of the valve body 14 for stable fixing on the equipment. A fixing flange 13 is fixedly installed on the upper surface of the base 10 for fixing the valve body 14, which facilitates subsequent machining.

[0019] Further reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 Two symmetrically arranged brackets 15 are fixedly installed on the upper surface of the base 10 on the back side of the valve body 14. The brackets 15 are L-shaped. A first electric push cylinder 16 is fixedly installed on the horizontal upper surface of the brackets 15. The output end of the first electric push cylinder 16 slides through the brackets 15 and is fixedly installed with a clamping box 17. A push rod 18 is slidably installed at the bottom of the clamping box 17. The push rod 18 is located directly above the two flanges of the valve body 14. A rubber block 19 is fixedly installed at the bottom end of the push rod 18. The lower surface of the clamping box 17 has grooves 21 on both sides of the push rod 18. Clamping plates 22 are slidably installed inside the grooves 21. The clamping plates 22 are located on both sides of the flanges of the valve body 14. The height of the push rod 18 is higher than that of the clamping plates 22. A push plate 20 is fixedly installed at the top of the push rod 18. A connecting rod 23 is rotatably installed between the push plate 20 and the two clamping plates 22. In use, the first electric push cylinder... The first electric push cylinder 16 moves the clamping box 17, push rod 18, and push block 19 downwards. When the push block 19 contacts the valve body 14, it pushes the push rod 18 upwards to avoid direct contact between the push rod 18 and the flange of the valve body 14, thus preventing damage. The upward movement of the push rod 18 drives the push plate 20 to pull the clamping plate 22 to move in the center via the connecting rod 23. When the push rod 18 is fully inside the clamping box 17, the first electric push cylinder 16 stops working. At this time, the clamping plate 22 clamps the flanges at both ends of the valve body 14, fixing the flanges of the valve body 14 from the top and both sides. With the use of the fixing flange 13, the valve body 14 can be stably fixed, improving the stability and processing quality during processing. When fixing the valve body 14, it can be inserted from the front of the bracket 15 for easy placement. At the same time, when fixing, both ends of the valve body 14 can be exposed, facilitating subsequent processing.

[0020] Further reference Figure 6A first damping block 24 is fixedly installed on the upper surface of the push plate 20, and a second damping block 26 is fixedly installed on the lower surface of the top of the inner cavity of the clamping box 17. A spring 25 is fixedly installed between the first damping block 24 and the second damping block 26. When the push rod 18 is inside the clamping box 17, the spring 25 is compressed. When the clamping of the valve body 14 flange is released, the first electric push cylinder 16 drives the clamping box 17 to move upward, and the spring 25 resets and pushes out the push rod 18, thereby resetting the clamping plate 22 and releasing the clamping fixation. The use of the spring 25 can quickly reset the push rod 18, prevent the clamping plate 22 from rubbing against the clamping box 17 when resetting, ensure that the reset force is not reduced, and improve the use effect. At the same time, the use of the first damping block 24 and the second damping block 26 can reduce vibration when the push rod 18 is reset, avoid the push rod 18 moving back and forth, thereby avoid the clamping plate 22 sliding back and forth inside the slide groove 21, reduce its wear, and improve its service life.

[0021] Further reference Figure 6 The top surfaces of the clamping plate 22 are fixedly equipped with anti-slip texture 27, which can improve the stability of the clamping plate 22 when in use, and at the same time prevent the clamping plate 22 from directly contacting the flange, thus preventing excessive clamping force and damage to the flange.

[0022] Further reference Figure 1 and Figure 2 A vacuum cleaner 28 is fixedly installed on the horizontal upper surface of the bracket 15 on one side of the first electric push cylinder 16. The suction end of the vacuum cleaner 28 is linked to a telescopic guide tube 29. A dust suction hood 30 is fixedly installed on one side of the clamping box 17. The top of the dust suction hood 30 is connected to the guide tube 29. When the flange of the valve body 14 is fixed, the dust suction hood 30 moves together with the clamping box 17, so that the dust suction hood 30 is located above the side of the flange being processed, close to the flange. When processing the flange, it can remove processing debris and protect the surrounding working environment. After processing, it can move up with the clamping box 17 to facilitate the removal of the valve body 14 and speed up the work efficiency.

[0023] Example 2: A tooling for machining the valve body of a regulating valve, a further embodiment based on Embodiment 1, is provided for reference. Figure 1 and Figure 4 A base plate 11 is provided below the base 10. A servo motor 36 is fixedly installed in the middle of the upper surface of the base plate 11. The output end of the servo motor 36 is fixed to the lower surface of the base 10. When the valve body 14 is processed, the servo motor 36 can be controlled to drive the connected base 10 to rotate, thereby enabling the valve body 14 to rotate, adjusting the processing angle of the valve body 14, and improving the processing effect.

[0024] Further reference Figure 4The upper surface of the base plate 11 has a multi-ring-shaped rotating groove 37 on the outside of the servo motor 36. The lower surface of the base 10 is fixedly installed with multiple support rods 38 that rotate inside the rotating grooves 37 to support the base 10 and improve its stability. When the base 10 rotates, the support rods 38 also rotate inside the rotating grooves 37, so that the base 10 can be supported when adjusting the angle, thus improving the performance.

[0025] Example 3: A tooling for machining the valve body of a regulating valve, further exemplified by embodiments one and two, is provided for reference. Figure 1 , Figure 2 and Figure 7 A fixing plate 31 is fixedly installed between two brackets 15. A second electric push cylinder 32 is fixedly installed on the upper surface of the fixing plate 31. The output end of the second electric push cylinder 32 passes through the fixing plate 31 and is fixedly installed with a conical sealing plug 33. An air hole 34 is opened inside the sealing plug 33. An air pump 35 is fixedly installed on the upper surface of the base 10 on the back side of the valve body 14. The air outlet of the air pump 35 is connected to the air hole 34. After the valve body 14 is processed, the second electric push cylinder 32 pushes the sealing plug 33 downward, inserts the fixing plate 31 into the top of the valve body 14, and the conical sealing plug 33 can seal it. Then, the air pump 35 is controlled to work and the flange is sealed. Air is injected into the valve body 14 through the air hole 34. A handheld gas flow meter can be placed at the flanges at both ends of the valve body 14. If the flow exceeds the allowable value (such as the standard leakage), the seal is unqualified; otherwise, it is qualified. If it is unqualified, processing continues.

[0026] Finally, it should be noted that the tooling for processing the valve body of the regulating valve in this utility model is intended to protect the various mechanical structures and related motion logic in this solution. Therefore, it does not elaborate on the various sensors, detectors, and driving components required for the actual operation of the specific mechanical structures. However, for those skilled in the art, various control systems and electrical connection methods, including various electrical components and driving components, can be completed using conventional technical means. As long as the beneficial effects or the specific actions during the above-mentioned work can be achieved, they can be implemented. This solution does not impose too many restrictions.

[0027] Furthermore, the first electric push cylinder 16, vacuum cleaner 28, second electric push cylinder 32, air pump 35, and servo motor 36 of the valve body processing fixture in this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative labor from technical personnel in this field.
