Description

Technical Field

[0001] This invention relates to the field of proportional valve core processing technology, specifically to a proportional valve core processing equipment and process with intelligent monitoring function. Background Technology

[0002] A proportional valve is a fluid control device consisting of a valve core, valve body, positioning device, and control device. The valve core is the key component of a proportional valve, controlling the liquid flow rate. It not only regulates flow but also achieves pressure equalization, pressure control, and energy saving. Due to its precise flow rate regulation, improved safety, increased production efficiency, low energy consumption, and fast response speed, proportional valves are widely used in various industrial production lines and automated control systems.

[0003] In the existing technology, the production and processing of proportional valve cores requires grinding, grooving and other processing. Since the grinding and grooving tools are in different positions, each time the processing method is changed, it is necessary to unfix, change the position of the processing equipment and refix. Moreover, after the proportional valve core body is changed and fixed, the whole body is displaced due to the change of position, so the staff needs to remeasure the position of the proportional valve core in order to process it accurately. This makes the production and processing of proportional valve cores quite troublesome, which affects the production efficiency of proportional valve cores. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the production and processing of proportional valve cores requires grinding, grooving, and other processing. Because the grinding and grooving tools are located in different positions, each time the processing method is changed, operations such as unfixing, changing the position of the processing equipment, and refixing are required. Furthermore, after the proportional valve core body is repositioned and refixed, the overall body shifts due to the repositioning, requiring workers to remeasure the position of the proportional valve core for accurate processing. This makes the production and processing of proportional valve cores cumbersome and affects the production efficiency of proportional valve cores. Therefore, this invention proposes a proportional valve core processing equipment and process with intelligent monitoring function.

[0009] In a preferred embodiment of the present invention, a pair of sliding grooves symmetrical about the center line of the sliding grooves are formed on the top of the outer wall of the placement plate; a pair of movable plates are slidably connected to the inner side wall of the sliding grooves; a circular rod is slidably connected to one side of the outer wall of each pair of movable plates, and one end of the outer wall of each pair of circular rods passes through the pair of movable plates; an arc-shaped block is fixedly connected to one opposite end of the outer wall of each pair of circular rods, and the arc-shaped block matches the clamping block; a third spring is fixedly connected to one opposite side of the outer wall of each pair of movable plates, and one end of the outer wall of each pair of third springs is fixedly connected to one side of the outer wall of each pair of arc-shaped blocks; a first double-threaded rod is rotatably connected to one side of the inner wall of each pair of sliding grooves, and one end of the outer wall of each pair of first double-threaded rods passes through the two pairs of movable plates and the pair of sliding grooves, and the pair of first double-threaded rods are threadedly connected to the two pairs of movable plates respectively; a third gear is fixedly connected to the outer side wall of the double-threaded shaft and the pair of first double-threaded rods, and a set of third gears meshes with each other.

[0010] In a preferred embodiment of the present invention, the arc surfaces of the set of clamping blocks and arc blocks are all provided with arc-shaped through grooves; an arc-shaped sliding groove is provided on one side of the inner wall of the arc-shaped through groove; a pair of arc-shaped sliders are slidably placed on the inner side wall of the arc-shaped sliding groove, and the outer side walls of the pair of arc-shaped sliders are slidably placed on the inner side wall of the arc-shaped through groove, and the arc-shaped sliders are convex in shape; an arc-shaped sliding plate is fixedly connected to one side of the outer wall of the pair of arc-shaped sliders, and a set of arc-shaped sliding plates are respectively matched with a set of clamping blocks and arc blocks.

[0011] In a preferred embodiment of the present invention, a limiting groove is formed on one side of the inner wall of the arc-shaped slide; a limiting block is fixed to one side of the inner wall of the limiting groove by a fourth spring, and the limiting block matches the arc-shaped slider; the two sides of one end of the outer wall of the limiting block are arc-shaped.

[0012] In a preferred embodiment of the present invention, the inner sidewalls of the two pairs of annular blocks are slidably connected to the outer sidewalls of a pair of rotating rods; the inner sidewalls of the pair of grinding discs and cutting blades are fixedly connected to the outer sidewalls of the two pairs of annular blocks; a second double-threaded rod is rotatably connected to one side of the outer wall of each pair of second gears, and the pair of second double-threaded rods respectively penetrate the two pairs of annular blocks and are threadedly connected to the two pairs of annular blocks; a worm gear is fixedly connected to the outer sidewall of each pair of second double-threaded rods; a worm is rotatably connected to one side of the outer wall of each pair of second gears through a second square plate, and the pair of worms respectively mesh with the pair of worm gears.

[0013] A manufacturing process for a proportional valve core with intelligent monitoring function includes the following steps:

[0014] Step 1: By placing the valve core body between a set of clamping blocks, the second motor drives the double-threaded shaft to rotate. The rotation of the double-threaded shaft will cause a pair of sliding blocks to move towards the center at the same time. The movement of the pair of sliding blocks will drive a set of clamping blocks to move through a pair of connecting plates, so that the set of clamping blocks clamps and fixes the middle part of the valve core body.

[0015] Step 2: By rotating the worm, the rotation of the worm will drive the worm wheel to rotate, the rotation of the worm wheel will drive the second double threaded rod to rotate, and the rotation of the second double threaded rod will drive a pair of annular blocks and cutting blades to move to both sides at the same time, so that the pair of cutting blades move to the two ends of the valve core body where cutting processing or grooving is required.

[0016] Step 3: The square plate is moved down by the hydraulic cylinder, which in turn moves the rotating plate, the circular plate, the rotating rod, and the cutting blade down. At this time, the first motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the first gear to rotate. The rotation of the first gear drives the rotating rod, the circular plate, and the cutting blade to rotate through the second gear, so that the cutting blade can cut or groove the valve core body.

[0017] Step 4: When the valve core body is cut or slotted, the hydraulic cylinder drives the square plate to move upward. At this time, pull the pull plate, which moves the locking rod out of the locking groove, thereby releasing the fixing of the rotating plate. Then rotate the rotating plate to make the grinding disc rotate to the position of the previous cutting blade, so that the grinding disc and the cutting blade are swapped. Then release the pull plate. At this time, the first spring will drive the circular block to retract. The movement of the circular block will drive the pull plate and the locking rod, so that the locking rod is locked into another locking groove. Repeat the adjustment operation to move the grinding disc to the two ends of the valve core body that need to be ground. Then the first motor drives the rotating shaft and the first gear to rotate, which drives the other second gear and the rotating rod to rotate, so that the grinding disc rotates and grinds the two ends of the valve core body.

[0018] Step 5: After the two ends of the valve core body are machined, the second motor drives the double-threaded shaft to reverse, causing a pair of clamping blocks to move to both sides, thus releasing the valve core body from its fixation.

[0019] Step Six: When the double-threaded shaft reverses, it will drive a pair of first double-threaded rods to rotate forward through a set of third gears. The forward rotation of the pair of first double-threaded rods will drive two pairs of moving plates to move towards the center at the same time, thereby causing the moving plates to move the circular rod and the arc block. This causes a set of arc blocks to clamp and fix both ends of the valve core body. Because the sliding block and the connecting plate are connected by the second spring, and the moving plate and the arc block are connected by the third spring, both the arc block and the clamping block have elasticity. When the sliding block moves to both sides, due to the elasticity of the second spring, the clamping block will also stick to the valve core body. When the clamping block completely leaves the valve core body, the arc block will contact the valve core body and fix it.

[0020] Step 7: At this point, both ends of the valve core body are fixed. Adjust the position of the cutting blade and the grinding disc, and repeat the cutting and grinding operations to cut, grind, or grooving the middle part of the valve core body.

[0021] Step 8: When grinding or cutting the two ends or the middle of the valve core body, arc-shaped sliders are slidably placed in the arc-shaped grooves and arc-shaped through grooves on the arc-shaped blocks or clamping blocks, and the arc-shaped sliding plate matches the arc-shaped surface of the arc-shaped blocks or clamping blocks; when a set of arc-shaped blocks or clamping blocks clamp and fix the valve core body, the arc-shaped sliding plate will first contact the valve core body, so that when the valve core body is fixed, the valve core body can be rotated to make the valve core body drive the arc-shaped sliding plate to slide, and the arc-shaped sliding plate will drive a pair of arc-shaped sliders to slide on the arc-shaped through grooves and arc-shaped grooves on the arc-shaped blocks or clamping blocks. When one of the arc-shaped sliders moves out of an arc-shaped block or clamping block, at this time the pair of arc-shaped sliders on the arc-shaped sliding plate will be on a pair of arc-shaped blocks and clamping blocks respectively, so that the valve core body can rotate when clamped and fixed, so that the valve core body can rotate on its own when grinding, cutting or grooving;

[0022] Step Nine: A limiting groove is made on one side of the inner wall of the arc-shaped slide, and a limiting block is fixed to the inner wall of the limiting groove by a fourth spring. When a pair of arc-shaped sliders on the arc-shaped slide are placed in the arc-shaped slide and the arc-shaped through groove, the arc-shaped sliders will be limited by the limiting block when they encounter it, thus limiting the arc-shaped sliders and preventing them from moving. This also limits the arc-shaped slide and prevents it from falling off. When rotating, because the two sides of one end of the outer wall of the limiting block are arc-shaped, the arc-shaped sliders will encounter the arc-shaped surface of the limiting block when they are moved by external force. This will cause the limiting block to drive the fourth spring to contract, allowing the valve core body to rotate.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. By pulling the pull plate, the pull plate moves the locking rod out of the locking groove, thereby releasing the fixing of the rotating plate. At this time, rotate the rotating plate to make the grinding disc rotate to the position of the previous cutting blade, so that the grinding disc and the cutting blade are interchanged. Then release the pull plate. At this time, the first spring will drive the circular block to retract. The movement of the circular block will drive the pull plate and the locking rod, so that the locking rod is locked into another locking groove, fixing the rotating plate and the square plate. Thus, this device can perform cutting, grooving, grinding and other processing on the valve core body without changing the equipment. This makes the operation of the device more convenient, optimizes the processing operation of the valve core body, and improves the production efficiency of the valve core body.

[0025] 2. By rotating the worm gear, the rotation of the worm gear will drive the worm wheel to rotate, which in turn will drive the second double-threaded rod to rotate. The rotation of the second double-threaded rod will drive a pair of annular blocks and cutting blades or grinding discs to move simultaneously to the sides or center. This allows the pair of cutting blades or grinding discs to be moved to the ends or center of the valve core body where cutting, grinding, or grooving is required for processing. This device allows for easy adjustment of the positions of the cutting blades and grinding discs according to the processing position of the valve core body, making it more convenient to process the valve core body in different positions. Furthermore, the ability to easily adjust the processing position using the cutting blades and grinding discs saves time in processing the entire valve core body and improves the production efficiency of the valve core body.

Detailed Implementation

[0038] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1-8As shown, a proportional valve core processing device with intelligent monitoring function includes a base 1 and an intelligent monitoring module; a placement plate 2 is fixedly connected to the top of the outer wall of the base 1; a support column 3 is fixedly connected to the top of the outer wall of the base 1, and the support column 3 is U-shaped; a hydraulic cylinder 4 is fixedly connected to the top of the inner wall of the support column 3; a square plate 5 is fixedly connected to the output end of the hydraulic cylinder 4, and the outer wall of the square plate 5 is slidably connected to the inner wall of the support column 3; a first circular through groove 6 is opened on one side of the outer wall of the square plate 5; a rotating plate 7 is rotatably connected to the inner wall of the first circular through groove 6; a fixing member is provided on one side of the outer wall of the rotating plate 7, and the rotating plate 7 is fixed by the fixing member. The fixing component includes a circular shell 8; a first motor 9 is fixedly connected to one side of the outer wall of the rotating plate 7 via a pair of fixing blocks; the output end of the first motor 9 is provided with a rotating shaft 10, and one end of the outer wall of the rotating shaft 10 penetrates the rotating plate 7; a first gear 11 is fixedly connected to one end of the rotating shaft 10 penetrating the outer wall of the rotating plate 7; a pair of second circular through slots 12 symmetrical about the center line of the rotating plate 7 are opened on one side of the outer wall of the rotating plate 7; circular plates 13 are rotatably connected to the inner side walls of the pair of second circular through slots 12; rotating rods 14 are fixedly connected to one side of the outer wall of the pair of circular plates 13; second gears 15 are fixedly connected to the outer side walls of the pair of rotating rods 14, and one The second gear 15 meshes with the first gear 11. A pair of grinding discs 17 and cutting blades 18 are respectively mounted on the outer walls of a pair of rotating rods 14 via a pair of annular blocks 16. When the valve core body is being processed, the first motor 9 drives the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 drives the first gear 11 to rotate. The rotation of the first gear 11, through the second gear 15, drives the rotating rods 14, the circular plate 13, and the cutting blades 18 to rotate, causing the cutting blades 18 to process the valve core body. When the cutting blades 18 have finished processing, the fixing of the rotating plate 7 is released by the fixing component, causing the rotating plate 7 to rotate and the grinding discs 17 to rotate. Before moving to the position before the cutting blade 18, the first motor 9 drives the rotating shaft 10 and the first gear 11 to rotate, which in turn drives the second gear 15 and the rotating rod 14 to rotate, causing the grinding disc 17 to rotate. The grinding disc 17 then grinds the valve core body. When the valve core body undergoes multiple processes such as cutting, grooving, and grinding, it is not necessary to remove the valve core body from its fixed position and replace the equipment to re-fix it. This device simplifies the processing steps of the valve core body, saves processing time, and further improves the production efficiency of the valve core body. It also makes it more convenient for workers to process the valve core body.

[0040] One end of the outer wall of the circular shell 8 is fixed to one edge of the outer wall of the rotating plate 7; a pair of symmetrical locking grooves 19 about the center line of the rotating plate 7 are opened on one side of the outer wall of the square plate 5; a circular block 20 is fixed to one side of the inner wall of the circular shell 8 by a first spring, and the outer side wall of the circular block 20 is slidably connected to the inner side wall of the circular shell 8; a pull plate 21 is fixed to one end of the outer wall of the circular block 20, and the pull plate 21 is U-shaped; a locking rod 22 is fixed to one side of the outer wall of the pull plate 21, and the locking rod 22 matches the locking groove 19. When the valve core body completes the cutting operation, by pulling the pull plate 21, the pull plate 21 drives the locking rod 22 to move out of the locking groove 19. By releasing the rotating plate 7, rotating the rotating plate 7 causes the grinding disc 17 to rotate to the position of the cutting blade 18, thus swapping the positions of the grinding disc 17 and the cutting blade 18. Then, releasing the pull plate 21 causes the first spring to retract the circular block 20. The movement of the circular block 20 causes the pull plate 21 and the locking rod 22 to engage in another locking groove 19, thus fixing the rotating plate 7 and the square plate 5. This allows the device to perform cutting, grooving, grinding, and other processing on the valve core body without changing the equipment, making the operation of the device more convenient, optimizing the processing operation of the valve core body, and improving the production efficiency of the valve core body.

[0041] A sliding groove 23 is formed at the top of the outer wall of the placement plate 2; a pair of sliding blocks 24 symmetrical about the center line of the sliding groove 23 are slidably connected to the inner side wall of the sliding groove 23; a connecting plate 25 is fixed to the opposite side of the outer wall of the pair of sliding blocks 24 by a second spring, and the connecting plate 25 is T-shaped, with the outer side wall of the connecting plate 25 slidably connected to the inner side wall of the sliding groove 23; a pair of clamping blocks 26 are fixed to the opposite side of the outer wall of the pair of connecting plates 25; a second motor 27 is fixed to the top of the outer wall of the base 1 by a first square plate; a double-threaded shaft 28 is provided at the output end of the second motor 27, and one end of the outer wall of the double-threaded shaft 28 penetrates the placement plate. The outer wall of the valve core 2 and a pair of sliding blocks 24 are rotatably connected to the inner wall of the sliding groove 23. The double-threaded shaft 28 is threadedly connected to the pair of sliding blocks 24. By placing the valve core body between a set of clamping blocks 26, the second motor 27 drives the double-threaded shaft 28 to rotate. The rotation of the double-threaded shaft 28 will cause the pair of sliding blocks 24 to move towards the center at the same time. The movement of the pair of sliding blocks 24 will drive the set of clamping blocks 26 to move through a pair of connecting plates 25, so that the set of clamping blocks 26 clamps and fixes the middle part of the valve core body, making it difficult for the two ends of the valve core body to move during processing, thus making the valve core body more stable during processing.

[0042] A pair of sliding grooves 29, symmetrical about the center line of the sliding grooves 23, are provided on the top of the outer wall of the placement plate 2; a pair of movable plates 30 are slidably connected to the inner side wall of the sliding grooves 29; a circular rod 31 is slidably connected to one side of the outer wall of each pair of movable plates 30, and one end of the outer wall of each pair of circular rods 31 passes through the pair of movable plates 30; an arc-shaped block 32 is fixedly connected to one opposite end of the outer wall of each pair of circular rods 31, and the arc-shaped block 32 matches the clamping block 26; a third spring is fixedly connected to one opposite side of the outer wall of each pair of movable plates 30, and one end of the outer wall of each pair of third springs is fixedly connected to one side of the outer wall of each pair of arc-shaped blocks 32; a first double-threaded rod 33 is rotatably connected to one side of the inner wall of each pair of sliding grooves 29, and one end of the outer wall of each pair of first double-threaded rods 33 passes through the two pairs of movable plates 30 and the pair of sliding grooves 29, and the pair of first double-threaded rods 33 are threadedly connected to the two pairs of movable plates 30 respectively;The outer walls of both the double-threaded shaft 28 and the pair of first double-threaded rods 33 are fixed with third gears 34, and the set of third gears 34 mesh with each other. After the two ends of the valve core body are machined, the second motor 27 drives the double-threaded shaft 28 to reverse, causing the pair of clamping blocks 26 to move to both sides, releasing the valve core body from its fixation. When the double-threaded shaft 28 reverses, it drives the pair of first double-threaded rods 33 to rotate forward through the set of third gears 34. The forward rotation of the pair of first double-threaded rods 33 will drive the two pairs of moving plates 30 to move towards the center simultaneously. The moving plate 30 drives the circular rod 31 and the arc-shaped block 32 to move, so that a set of arc-shaped blocks 32 clamps and fixes both ends of the valve core body. Because the sliding block 24 and the connecting plate 25 are connected by a second spring, and the moving plate 30 and the arc-shaped block 32 are connected by a third spring, both the arc-shaped block 32 and the clamping block 26 have elastic force. When the sliding block 24 moves to both sides, due to the elastic force of the second spring, the clamping block 26 will also stick to the valve core body. When the clamping block 26 completely leaves the valve core body, the arc-shaped block 32 will contact the valve core body and fix it, so that the device... When changing the clamping position, the valve core body remains unchanged and does not move. Furthermore, this device simultaneously releases the middle of the valve core body and fixes both ends, thus saving clamping and fixing time, as well as time for adjusting the valve core body position. This makes the valve core body more stable during different processing operations, improving both production efficiency and quality. Because the third gear 34 on the double-threaded shaft 28 is located in the center, when the double-threaded shaft 28 rotates forward, a pair of first double-threaded rods 33 rotate forward; when the double-threaded shaft 28 rotates in reverse, the pair of first double-threaded rods 33 rotate forward. This reduces the time required to fix the valve core body, improving production efficiency while preventing displacement during fixing and releasing, thus ensuring processing quality. The overall structure of this device when fixing the valve core body allows for processing as a whole, while also providing a large contact area between the valve core body and the clamping block 26 or arc-shaped block 32, making it less prone to bending or deformation during processing.

[0043] The inner walls of two pairs of annular blocks 16 are slidably connected to the outer walls of a pair of rotating rods 14; the inner walls of a pair of grinding discs 17 and cutting blades 18 are fixedly connected to the outer walls of the two pairs of annular blocks 16; a pair of second double-threaded rods 41 are rotatably connected to one side of the outer wall of each pair of second gears 15, and the pair of second double-threaded rods 41 pass through the two pairs of annular blocks 16 respectively, and the pair of second double-threaded rods 41 are threadedly connected to the two pairs of annular blocks 16 respectively; a worm gear 42 is fixedly connected to the outer wall of each pair of second double-threaded rods 41; a worm 43 is rotatably connected to one side of the outer wall of each pair of second gears 15 through a second square plate, and the pair of worms 43 mesh with the pair of worm gears 42 respectively. When the valve core body is ground, cut, or grooved, the valve core is rotatably connected to the worm gears 42. By rotating the worm gear 43, the rotation of the worm gear 43 will drive the worm wheel 42 to rotate, and the rotation of the worm wheel 42 will drive the second double threaded rod 41 to rotate. The rotation of the second double threaded rod 41 will drive a pair of annular blocks 16 and cutting blades 18 or grinding discs 17 to move to both sides simultaneously, so that the pair of cutting blades 18 or grinding discs 17 are moved to the two ends or the middle of the valve core body where cutting or grooving is required. This makes it easy for the device to be adjusted according to the processing position of the valve core body, making it more convenient to process the valve core body in different positions. Moreover, the cutting blades 18 and grinding discs 17 can be easily adjusted to adjust the processing position, so that the device can save the processing time of the entire valve core body, thereby improving the production efficiency of the valve core body.

[0044] The intelligent monitoring module collects the valve core shape and size during the valve core body processing and provides monitoring and early warning. The specific process is as follows:

[0045] The valve core is divided into several monitoring segments. The shape and size of each monitoring segment are identified. The size of the monitoring segment is compared with the preset target size. The size error value between the two is calculated. If the size error value is greater than the set error threshold, the size warning command of the corresponding monitoring segment is generated and a warning is issued.

[0046] If the size error value is less than or equal to the set error threshold, the shape of the monitored segment is compared with the preset target shape to obtain the shape error value. The shape error value is converted into the moving distance of the cutting blade (18) according to a certain ratio, and the cutting blade (18) is controlled to cut the valve core body corresponding to the monitored segment according to the corresponding moving distance. The specific shape comparison process is as follows: mark points are set on the shape of the monitored segment and the preset target shape, and the marks corresponding to the two shapes are made to coincide. Then, several corresponding calculation points are set on the two current conditions respectively. If the calculation points between the two do not coincide, the deviation value between the two is calculated, and the average value of all the deviation values ​​of the calculation points is calculated to obtain the shape error value.

[0047] Example 2: Please refer to Figures 9-10As shown, both the clamping block 26 and the arc-shaped block 32 have arc-shaped through grooves 35 on their arc-shaped surfaces; an arc-shaped sliding groove 36 is formed on one side of the inner wall of the arc-shaped through groove 35; a pair of arc-shaped sliders 37 are slidably placed on the inner side wall of the arc-shaped sliding groove 36, and the outer side walls of the pair of arc-shaped sliders 37 are slidably placed on the inner side wall of the arc-shaped through groove 35, and the arc-shaped sliders 37 are convex in shape; an arc-shaped sliding plate 38 is fixedly connected to one side of the outer wall of the pair of arc-shaped sliders 37, and a set of arc-shaped sliding plates 38... Each component is matched with a set of clamping blocks 26 and arc-shaped blocks 32. When the valve core body is ground or cut at both ends or in the middle, an arc-shaped slider 37 is slidably placed in the arc-shaped groove 36 and arc-shaped through groove 35 on the arc-shaped block 32 or clamping block 26, and an arc-shaped sliding plate 38 matches the arc-shaped surface of the arc-shaped block 32 or clamping block 26. When the set of arc-shaped blocks 32 or clamping blocks 26 clamps and fixes the valve core body, the arc-shaped sliding plate 38 will first contact the valve core body, thereby... When the valve core body is fixed, rotating the valve core body causes the arc-shaped slide plate 38 to slide, which in turn causes a pair of arc-shaped sliders 37 to slide on the arc-shaped through grooves 35 and arc-shaped sliding grooves 36 on the arc-shaped block 32 or clamping block 26. When one of the arc-shaped sliders 37 moves out of an arc-shaped block 32 or clamping block 26, the pair of arc-shaped sliders 37 on the arc-shaped slide plate 38 will be on the pair of arc-shaped blocks 32 and clamping blocks 26 respectively, allowing the valve core body to rotate when clamped and fixed. This allows the valve core body to rotate during grinding, cutting, or grooving, and the rotation of the valve core body can be coordinated with the processing of the cutting blade 18 and the grinding disc 17. This allows the valve core body to be processed more effectively in the rotating state, and effectively improves the processing efficiency of the valve core body. This not only improves the processing efficiency of the valve core body, but also makes it easier to process and reduces the processing difficulty of the valve core body.

[0048] A limiting groove 39 is formed on one side of the inner wall of the arc-shaped slide 36; a limiting block 40 is fixed to one side of the inner wall of the limiting groove 39 by a fourth spring, and the limiting block 40 matches the arc-shaped slider 37; the two sides of one end of the outer wall of the limiting block 40 are arc-shaped. Because the limiting groove 39 is formed on one side of the inner wall of the arc-shaped slide 36 and the limiting block 40 is fixed to one side of the inner wall of the limiting groove 39 by a fourth spring, when a pair of arc-shaped sliders 37 on the arc-shaped slide plate 38 are placed in the arc-shaped slide 36 and the arc-shaped through groove 35, when the arc-shaped slider 37 encounters the limiting block 40, it will be limited by the limiting block 40, thus limiting the arc-shaped slider 37 and preventing it from moving. The movement of the curved slide plate 38 prevents it from falling off. When rotating, the curved slider 37 encounters the curved surface of the limiting block 40 when it is moved by external force because the two sides of one end of the outer wall of the limiting block 40 are curved. This causes the limiting block 40 to drive the fourth spring to contract, allowing the valve core body to rotate. This makes it less likely for the curved slide plate 38 and the curved slider 37 to fall off when normally placed on the clamping block 26 or the curved block 32. At the same time, the limiting block 40 will not obstruct the rotation of the curved slide plate 38 and the curved slider 37 when rotation is required, making the operation of this device more convenient and reducing the difficulty of using the device.

[0049] In use, the valve core body is placed between a set of clamping blocks 26. The second motor 27 drives the double-threaded shaft 28 to rotate. The rotation of the double-threaded shaft 28 causes a pair of sliding blocks 24 to move simultaneously towards the center. This movement of the sliding blocks 24, via a pair of connecting plates 25, moves the set of clamping blocks 26, thus clamping and fixing the middle portion of the valve core body. This prevents the valve core body from moving during processing, making the processing more stable. After the valve core body is fixed, rotating the worm gear 43 causes the worm wheel 42 to rotate. The rotation of the worm wheel 42 then causes the second double-threaded rod 41 to rotate, which in turn rotates a pair of annular blocks 16 and a cutting blade 18. Simultaneously, the cutting blades 18 move to both sides, positioning them at the ends of the valve core body where cutting or grooving is required. This allows the device to be easily adjusted according to the processing position of the valve core body, making it more convenient to process the valve core body in different positions. Furthermore, the easy adjustment of the processing position via the cutting blades 18 and grinding disc 17 saves time in processing the entire valve core body, thereby improving production efficiency. Once the cutting blades 18 and grinding disc 17 are adjusted to the appropriate positions, the hydraulic cylinder 4 drives the square plate 5 downwards. This, in turn, causes the square plate 5 to drive the rotating plate 7, the circular plate 13, the rotating rod 14, and the cutting blades 18 downwards. At this time, the first motor 9 drives the rotating shaft 10 to rotate. The rotation drives the first gear 11 to rotate. The rotation of the first gear 11 drives the rotating rod 14, the circular plate 13, and the cutting blade 18 to rotate via the second gear 15. This causes the cutting blade 18 to cut or groove the valve core body. When the valve core body has completed the cutting or grooving, the hydraulic cylinder 4 moves the square plate 5 upward. At this time, the pull plate 21 is pulled, causing the pull plate 21 to move the locking rod 22 out of the locking groove 19, thereby releasing the fixing of the rotating plate 7. Then, the rotating plate 7 is rotated, causing the grinding disc 17 to rotate to the previous position of the cutting blade 18, thus swapping the positions of the grinding disc 17 and the cutting blade 18. Then the pull plate 21 is released. At this time, the first spring will cause the circular block 20 to retract. The movement of the circular block 20 will drive the pull plate 21 and the locking rod 22, causing the locking rod 22 to retract. 2. Insert the blade into another slot 19, and repeat the adjustment operation to move the grinding disc 17 to the two ends of the valve core body that need to be ground. Then, the first motor 9 drives the rotating shaft 10 and the first gear 11 to rotate, which in turn drives the second gear 15 and the rotating rod 14 to rotate, thereby rotating the grinding disc 17 to grind the two ends of the valve core body. This device only requires pulling the pull plate 21 and rotating the rotating plate 7 to change the position of the cutting blade 18 and the grinding disc 17 for grinding. This eliminates the need to remove the valve core body from the fixing device and replace the equipment to re-fix it, simplifying the processing steps of the valve core body, saving processing time, and further improving the production efficiency of the valve core body.Furthermore, it makes it more convenient for workers to process the valve core body. After the two ends of the valve core body are processed, the second motor 27 drives the double-threaded shaft 28 to reverse, causing a pair of clamping blocks 26 to move to both sides, releasing the valve core body from its fixation. When the double-threaded shaft 28 reverses, it will drive a pair of first double-threaded rods 33 to rotate forward through a set of third gears 34. The forward rotation of the pair of first double-threaded rods 33 will drive two pairs of moving plates 30 to move towards the center simultaneously, thereby causing the moving plates 30 to drive the circular rod 31 and the arc-shaped block 32 to move, so that a set of arc-shaped blocks 32 clamps and fixes the two ends of the valve core body. Because the sliding block 24 and the connecting plate 25 are connected by a second spring, and the moving plate 30 and the arc-shaped block 32 are connected by a third spring, the arc-shaped block 32 and the clamping block 26 are fixed together. All six components have elasticity, causing the sliding block 24 to move to both sides. Due to the elasticity of the second spring, the clamping block 26 will also adhere to the valve core body. When the clamping block 26 completely leaves the valve core body, the arc-shaped block 32 will contact and fix the valve core body, ensuring that the position of the valve core body will not move and will remain unchanged when the clamping position of this device is changed. Furthermore, this device fixes both ends of the valve core body while releasing the middle of the valve core body, thus saving the clamping and fixing time as well as the time for adjusting the position of the valve core body. This makes the valve core body more stable during different processing operations, improving the production efficiency of the valve core body and ensuring production quality. Moreover, because the third gear 34 on the double-threaded shaft 28 is located in the center position, when the double-threaded shaft 28 rotates clockwise, a pair of... The first double-threaded rod 33 rotates forward, while the double-threaded shaft 28 rotates in reverse. This reduces the time required to fix the valve core body, improving production efficiency and preventing displacement during fixing and unfixing, thus ensuring the processing quality of the valve core body. When both ends of the valve core body are fixed, the cutting blade 18 and grinding disc 17 are adjusted to the middle position of the valve core body, and the cutting and grinding operations are repeated to cut, grind, or groove the middle of the valve core body. When the two ends or the middle of the valve core body are being ground or cut, an arc-shaped slider 37 is slidably placed in the arc-shaped groove 36 and arc-shaped through groove 35 on the arc-shaped block 32 or clamping block 26, and an arc-shaped sliding plate 38 is connected to the arc-shaped sliding groove 36. The arc-shaped surfaces of the shaped blocks 32 or clamping blocks 26 are matched; when a set of arc-shaped blocks 32 or clamping blocks 26 clamp and fix the valve core body, the arc-shaped sliding plate 38 will first contact the valve core body, so that when the valve core body is fixed, the valve core body can be rotated to make the valve core body drive the arc-shaped sliding plate 38 to slide, so that the arc-shaped sliding plate 38 drives a pair of arc-shaped sliders 37 to slide on the arc-shaped through grooves 35 and arc-shaped sliding grooves 36 on the arc-shaped blocks 32 or clamping blocks 26. When one of the arc-shaped sliders 37 moves out of an arc-shaped block 32 or clamping block 26, at this time the pair of arc-shaped sliders 37 on the arc-shaped sliding plate 38 will be on a pair of arc-shaped blocks 32 and clamping blocks 26 respectively, so that the valve core body can rotate when clamped and fixed, so that the valve core body can rotate on its own when grinding, cutting or grooving.This allows the rotation of the valve core body to coordinate with the machining of the cutting blade 18 and the grinding disc 17, enabling more efficient machining of the valve core body while it is rotating. This significantly improves machining efficiency and makes machining easier, reducing the difficulty of machining the valve core body. Furthermore, by creating a limiting groove 39 on one side of the inner wall of the arc-shaped slide groove 36, and fixing a limiting block 40 to one side of the inner wall of the limiting groove 39 via a fourth spring, when a pair of arc-shaped sliders 37 on the arc-shaped slide plate 38 are placed in the arc-shaped slide groove 36 and the arc-shaped through groove 35, the arc-shaped sliders 37 will be limited by the limiting block 40 when they encounter it. The curved slider 37 is limited and will not move, and the curved slide plate 38 is limited and will not fall off. When rotating, because the outer wall of the limiting block 40 has two curved sides, the curved slider 37 will encounter the curved surface of the limiting block 40 when it is moved by external force. This causes the limiting block 40 to drive the fourth spring to contract, allowing the valve core body to rotate. This prevents the curved slide plate 38 and curved slider 37 from falling off when normally placed on the clamping block 26 or the curved block 32. At the same time, the limiting block 40 will not obstruct the rotation of the curved slide plate 38 and curved slider 37 when rotation is needed, making the operation of this device more convenient and reducing the difficulty of using it.

7. A manufacturing process for a proportional valve core with intelligent monitoring function, characterized in that, The apparatus for processing a proportional valve core with intelligent monitoring function as described in any one of claims 1-5 includes the following steps: Step 1: By placing the valve core body between a set of clamping blocks (26), the second motor (27) drives the double threaded shaft (28) to rotate. The rotation of the double threaded shaft (28) will cause a pair of sliding blocks (24) to move towards the center at the same time. The movement of the pair of sliding blocks (24) will drive a set of clamping blocks (26) to move through a pair of connecting plates (25), so that the set of clamping blocks (26) clamps and fixes the middle part of the valve core body. Step 2: By rotating the worm (43), the rotation of the worm (43) will drive the worm wheel (42) to rotate, the rotation of the worm wheel (42) will drive the second double threaded rod (41) to rotate, and the rotation of the second double threaded rod (41) will drive a pair of annular blocks (16) and cutting blades (18) to move to both sides at the same time, so that the pair of cutting blades (18) move to the two ends of the valve core body where cutting processing or grooving is required; Step 3: The square plate (5) is moved down by the hydraulic cylinder (4), which in turn moves the rotating plate (7), the circular plate (13), the rotating rod (14), and the cutting blade (18) down. At this time, the first motor (9) drives the rotating shaft (10) to rotate. The rotation of the rotating shaft (10) drives the first gear (11) to rotate. The rotation of the first gear (11) drives the rotating rod (14), the circular plate (13), and the cutting blade (18) to rotate through the second gear (15), so that the cutting blade (18) can cut or groove the valve core body. Step 4: When the valve core body is cut or slotted, the hydraulic cylinder (4) moves the square plate (5) upward. At this time, the pull plate (21) is pulled, causing the pull plate (21) to move the locking rod (22) out of the locking groove (19), thereby releasing the fixing of the rotating plate (7). At this time, the rotating plate (7) is rotated, causing the grinding disc (17) to rotate to the position of the previous cutting blade (18), so that the grinding disc (17) and the cutting blade (18) are swapped. Then the pull plate (21) is released. At this time, the first spring will drive the circular block (20) to retract, and the circular block (20) will retract. The movement of 0) will drive the pull plate (21) and the locking rod (22), so that the locking rod (22) is locked into another locking groove (19). Then the adjustment operation is repeated to move the grinding disc (17) to the two ends of the valve core body that need to be ground. Then the first motor (9) drives the rotating shaft (10) and the first gear (11) to rotate, so that the first gear (11) drives another second gear (15) and the rotating rod (14) to rotate, so that the grinding disc (17) rotates and the grinding disc (17) grinds the two ends of the valve core body. Step 5: After the two ends of the valve core body are processed, the second motor (27) drives the double threaded shaft (28) to reverse, causing a pair of clamping blocks (26) to move to both sides, releasing the valve core body from the fixation. Step 6: When the double-threaded shaft (28) reverses, it will drive a pair of first double-threaded rods (33) to rotate forward through a set of third gears (34). The forward rotation of the pair of first double-threaded rods (33) will drive two pairs of moving plates (30) to move towards the center at the same time, so that the moving plates (30) drive the circular rod (31) and the arc block (32) to move, so that a set of arc blocks (32) clamps and fixes the two ends of the valve core body. Since the sliding block (24) and the connecting plate (25) are connected by the second spring, and the moving plate (30) and the arc block (32) are connected by the third spring, the arc block (32) and the clamping block (26) both have elastic force. When the sliding block (24) moves to both sides, due to the elastic force of the second spring, the clamping block (26) will also stick to the valve core body. When the clamping block (26) completely leaves the valve core body, the arc block (32) will contact the valve core body and fix it. Step 7: At this time, both ends of the valve core body are fixed, that is, adjust the position of the cutting blade (18) and the grinding disc (17), repeat the cutting and grinding operation, so that the middle part of the valve core body is cut, ground or grooved. Step 8: When the valve core body is being ground or cut at both ends or in the middle, an arc-shaped slider (37) is slidably placed in the arc-shaped groove (36) and arc-shaped through groove (35) on the arc-shaped block (32) or clamping block (26), and the arc-shaped sliding plate (38) matches the arc-shaped surface of the arc-shaped block (32) or clamping block (26); when a set of arc-shaped blocks (32) or clamping blocks (26) clamps and fixes the valve core body, the arc-shaped sliding plate (38) will first contact the valve core body, so that when the valve core body is fixed, by rotating the valve core body, the valve core body drives the arc-shaped sliding plate (38) to move the arc-shaped sliding plate (37) to move ... The curved slide plate (38) slides, causing the curved slide plate (38) to drive a pair of curved sliders (37) to slide on the curved through groove (35) and curved slide groove (36) on the curved block (32) or clamping block (26). When one of the curved sliders (37) moves out of a curved block (32) or clamping block (26), the pair of curved sliders (37) on the curved slide plate (38) will be on a pair of curved blocks (32) and clamping blocks (26) respectively, causing the valve core body to rotate when clamped and fixed, thereby causing the valve core body to rotate when grinding, cutting or grooving. Step 9: A limiting groove (39) is opened on one side of the inner wall of the arc-shaped slide (36), and a limiting block (40) is fixed on one side of the inner wall of the limiting groove (39) by a fourth spring. When a pair of arc-shaped sliders (37) on the arc-shaped slide plate (38) are placed in the arc-shaped slide (36) and the arc-shaped through groove (35), when the arc-shaped slider (37) encounters the limiting block (40), it will be limited by the limiting block (40), so that the arc-shaped slider (37) will not move, and the arc-shaped slide plate (38) will be limited, so that the arc-shaped slide plate (38) will not fall off. When rotating, because the two sides of one end of the outer wall of the limiting block (40) are arc-shaped, the arc-shaped slider (37) will encounter the arc surface of the limiting block (40) when it is moved by external force, so that the limiting block (40) drives the fourth spring to contract, causing the valve core body to rotate.
