Description

Technical Field

[0001] The invention relates to the technical field of valve body grinding, in particular to a valve body grinding device for a precision fluid valve. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, non-return, pressure stabilization, flow diversion and overflow pressure relief. Valves can be used to control the flow of various types of fluids such as air, water vapor, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are often in relatively harsh working conditions and are subject to high-temperature corrosion and impact from gasoline, diesel and other gases, as well as friction between the valve itself and the valve seat; therefore, valve materials must have sufficient thermal strength, high-temperature corrosion resistance, oxidation resistance, wear resistance and impact resistance at the highest working temperature. As an important part of the valve, the valve body is mainly forged from valve steel, which is generally made of A105 steel. In the production process of the valve body forgings, the initial appearance of the formed valve body forgings is relatively rough. In order to make the surface smooth and bright, it is necessary to use grinding equipment to grind it. Fluid valves are also a type of valve.

[0003] In this regard, China has applied for patent number: CN116787286B, which discloses an all-round grinding device for valve body production, including a frame; a moving component for controlling the lateral movement of the valve body; a grinding component for automatically grinding the valve body; and a shifting and swinging component for controlling the downward movement and swinging of the upper grinding device. The all-round grinding device for valve body production can automatically grind the upper surface and the left and right surfaces of the valve body through the provided grinding components, and as the moving component pushes the valve body forward, the grinding device on the opposite side automatically contracts inward to contact and grind the valve body, and the grinding belt can change its angle when contacting the valve body, so as to wrap the surface of the valve body and realize friction grinding of multiple aspects of the surface, thereby realizing automatic grinding of the valve body, improving the efficiency of grinding, and reducing the input of labor, directly avoiding the operator from inhaling dust into the body during manual grinding, and safety issues during grinding.

[0004] However, in actual use, since most valves are tubular, when a grinding belt is used for grinding, the grinding belt will be displaced when it contacts the outer surface of the valve, so that the grinding belt will not always fit the outer surface of the valve, so that the degree of grinding of the outer surface of the valve body after overall grinding is uneven, and when grinding the valve in the prior art, the inner and outer walls of the valve cannot be grinded at the same time, and a certain amount of debris will be generated during the grinding process. If the debris is not handled in time, it will affect the subsequent grinding effect between the grinding disc and the valve, so it has certain limitations. Therefore, it has become an urgent problem to be solved for us to perfect and improve the above-mentioned problems. Summary of the invention

[0005] The object of the present invention is to provide a valve body polishing equipment for precision fluid valves to solve the problem raised in the above background technology that since most valves are tubular, when polishing with a polishing belt, the polishing belt will be displaced when contacting the outer surface of the valve, so that the polishing belt will not always fit the outer surface of the valve, so that the polishing degree of the outer surface of the valve body after overall polishing is uneven, and when polishing the valve in the prior art, the inner and outer walls of the valve cannot be polished at the same time, and a certain amount of debris will be generated during the polishing process.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The valve body grinding equipment of the precision fluid valve comprises a support frame, a fluid valve body, a fixing plate, a cylinder body, a connecting ring, a forward and reverse motor body, a rotating shaft, a stabilizing ring, a stabilizing block, a mounting ring, a grinding sheet, a guide groove, a gear body, a fixing ring, a mounting bearing, a first rotating gear and a second rotating gear. When in use, the fluid valve body is first inserted and installed into the interior of the support frame, and then the outer surface of the support frame is abutted by four sets of fixing blocks and mounting abutting columns, so that the fluid valve body can be stably installed between the rotating disk, and the overall fluid valve body installation effect is relatively stable. Then, by starting the cylinder body, the connecting ring can be driven to move to the left through the cylinder body, and then the forward and reverse motor body inside the connecting ring is started, and then After that, the forward and reverse motor body will drive the rotating shaft to rotate, and then the rotating shaft will drive the stabilizing ring and the stabilizing block to rotate, and then the stabilizing block will drive the mounting ring and the grinding disc to rotate, and then the grinding disc will rotate inside the operating table, and at this time the outer surface of the grinding disc can contact the inner wall of the fluid valve body, and the inner wall of the fluid valve body is ground by the grinding disc, and at this time the grinding disc will also follow the cylinder body to move slowly to the left, so the grinding disc can move to the left while grinding the inner wall of the fluid valve body, and the grinding disc can always grind with the inner wall of the fluid valve body, which solves the problem of displacement when the grinding belt contacts the inner wall of the fluid valve body when grinding in the past, and the grinding can be performed by operating the guide groove The gear wheel is driven by the second gear and the second gear is driven by the first gear to move forward, and the gear wheel is driven by the second gear to move backward, so that the gear wheel can move forward and backward, and the gear wheel can move backward and backward, so that the gear wheel can move backward ... The material of the rubber scraper is relatively soft. When the rubber scraper hits the resistance rod, the resistance rod will bend the rubber scraper. After the rubber scraper leaves the surface of the resistance rod, the rubber scraper will rebound quickly, so that the debris on the surface of the rubber scraper will also quickly leave the surface of the rubber scraper. The overall cleaning effect is better. Similarly, the first rotating gear can also complete the same operation as the second rotating gear, and the inner wall of the fluid valve body can be cleaned as a whole. The fixing ring is fixedly installed on the rotating shaft. At this time, the mounting bearing is movably installed on the outer surface of the fixing ring. Therefore, when the rotating shaft rotates, it will not drive the mounting bearing to rotate as a whole. At this time, the mounting bearing rotates through the meshing of the gear body with the first rotating gear and the second rotating gear, which reflects the functionality of the design.

[0019] The valve body polishing equipment of the precision fluid valve is provided with an L-shaped support plate, a base body, a first polished arc piece, a mounting frame, a connecting column, a second polished arc piece, a rotating column, a protrusion, a rotating cylinder, a groove, a rotating disk, a fixed block and a mounting abutment column. When in use, the cylinder body first moves to the left, at which time the cylinder body will drive the L-shaped support plate to move to the left, and then the L-shaped support plate will drive the base body to move to the left, at which time the back side of the first polished arc piece will abut against the front surface of the fluid valve body, and when the first polished arc piece moves, the first polished arc piece will drive the mounting frame and the connecting column to move, at which time the back side of the second polished arc piece will also abut against the fluid valve body. The front surface of the body valve body, and the first polishing arc piece and the second polishing arc piece are both provided with two groups, and then the front and rear surfaces of the fluid valve body can be always polished by the two groups of the first polishing arc piece and the second polishing arc piece, and the first polishing arc piece and the second polishing arc piece slide inside the slide groove through the limit slider when moving, so that the overall stability of the first polishing arc piece and the second polishing arc piece when moving is good, and the inner and outer surfaces of the fluid valve body can be polished at the same time through the above operation, and the polishing piece is in stable contact with the inner and outer walls of the fluid valve body during polishing, and then the rotating shaft will also drive the rotating column to rotate, and when the rotating column rotates, the rotating column will drive the protrusion to rotate At this time, the convex block is installed inside the groove, so that the rotating column will drive the rotating cylinder to rotate, and then the rotating cylinder will drive the rotating disk to rotate, and the overall connection between the rotating disk and the fluid valve body is relatively stable, so the rotating disk can drive the fluid valve body to rotate through the fixed block and the installation interference column, and the rotating column can also telescope and slide inside the rotating cylinder through the adaptation of the convex block and the groove, and the forward and reverse motor body can rotate forward and reverse, and the cylinder body can also telescope, and the fluid valve body can rotate forward 180 degrees and then reverse 180 degrees during grinding, so that after the fluid valve body rotates, the grinding efficiency is higher when it is polished by the grinding sheet, the first grinding arc sheet and the second grinding arc sheet, and at the same time When the motor body rotates forward and reverse, the gear body will also rotate forward and reverse, so that the rotation direction of the first rotating gear and the second rotating gear will also change. By changing the rotation direction of the first rotating gear, the second rotating gear and the fluid valve body, the impurity cleaning effect on the inner wall of the fluid valve body is better. Subsequently, the transmission mechanism is also driven to rotate through the rotating shaft, and then the fan body is driven to rotate through the transmission mechanism. When the fan body rotates, the debris generated on the inner wall of the fluid valve body can be cleaned, so that the cleaning speed of the rubber scraper becomes faster during scraping, and the position of the transmission mechanism is limited by the second limit frame, which reflects the ingenuity of the design.

A connecting column 28 is fixedly connected to the left surface of the mounting frame 27, and a second polished arc piece 29 is fixedly connected to the back of the connecting column 28. The backs of the first polished arc piece 26 and the second polished arc piece 29 fit the front surface of the fluid valve body 4. The first polished arc piece 26 and the second polished arc piece 29 are both provided with two groups, and the two groups of the first polished arc piece 26 and the second polished arc piece 29 fit the front and rear surfaces of the fluid valve body 4 respectively. A rotating column 30 is fixedly connected to the left surface of the stabilizing ring 10, and a protrusion 31 is installed on the outer surface of the rotating column 30. A rotating cylinder 32 is provided on the outer surface of the protrusion 31. A groove 33 is provided on the inner side wall of the rotating cylinder 32, and the groove 33 and the protrusion 31 are mutually connected. Adaptation, a rotating disk 34 is fixedly connected to the left surface of the rotating cylinder 32, and a fixed block 35 is evenly installed on the outer surface of the rotating disk 34. An installation abutment column 36 is arranged inside the fixed block 35. Four groups of fixed blocks 35 are arranged, and a first limit frame 37 is arranged on the left surface of the rotating disk 34. A transmission mechanism 38 is installed on one side of the surface of the rotating shaft 9. A second limit frame 39 is arranged on the right surface of the transmission mechanism 38. The second limit frame 39 is installed on the upper surface of the connecting ring 7. A fan body 40 is fixedly connected to the left surface of the transmission mechanism 38. A slide groove 42 is opened on the top surface of the operating table 1. A limit slider 41 is arranged inside the slide groove 42. The limit slider 41 is installed on the lower surface of the base body 25. Figure 1The state of the fluid valve body 4 is a state of rotating ninety degrees. When the cylinder body 6 moves to the left, the cylinder body 6 will drive the L-shaped support plate 24 to move to the left, and then the L-shaped support plate 24 will drive the base body 25 to move to the left. At this time, the back side of the first polished arc piece 26 will contact the front surface of the fluid valve body 4. When the first polished arc piece 26 moves, the first polished arc piece 26 will drive the mounting frame 27 and the connecting column 28 to move. At this time, the back side of the second polished arc piece 29 will also contact the front surface of the fluid valve body 4, and the first polished arc piece 26 and the second polished arc piece 29 are both provided with two groups, and then the two groups of the first polished arc piece 26 and the second polished arc piece 29 can be The front and rear surfaces of the fluid valve body 4 are always subjected to resistance grinding, and the first grinding arc piece 26 and the second grinding arc piece 29 slide inside the slide groove 42 through the limit slider 41 when moving, so that the first grinding arc piece 26 and the second grinding arc piece 29 have better overall stability when moving. Through the above operation, the inner and outer surfaces of the fluid valve body 4 can be grinded at the same time, and the grinding piece is in stable contact with the inner and outer walls of the fluid valve body 4 during grinding. Then the rotating shaft 9 will also drive the rotating column 30 to rotate. When the rotating column 30 rotates, the rotating column 30 will drive the protrusion 31 to rotate. At this time, the protrusion 31 is installed in the groove 33, so that the rotating column 30 will drive the rotating cylinder 32 to rotate, and then the rotating cylinder 32 will drive The rotating disk 34 is driven to rotate, and the overall connection between the rotating disk 34 and the fluid valve body 4 is relatively stable. Therefore, the rotating disk 34 can drive the fluid valve body 4 to rotate through the fixed block 35 and the installation abutment column 36. At the same time, the rotating column 30 can also telescope and slide inside the rotating cylinder 32 through the adaptation of the protrusion 31 and the groove 33, and the forward and reverse motor body 8 can rotate forward and reverse, and the cylinder body 6 can also telescope. When grinding, the fluid valve body 4 can rotate forward 180 degrees and then reverse 180 degrees. Therefore, after the fluid valve body 4 is rotated, it is more efficient to grind through the grinding sheet 13, the first grinding arc sheet 26 and the second grinding arc sheet 29, and the grinding area is relatively complete. Similarly, when the forward and reverse motor body 8 is When rotating forward and reverse, the gear body 15 will also rotate forward and reverse, so that the rotation direction of the first rotating gear 18 and the second rotating gear 19 will also change. By changing the rotation direction of the first rotating gear 18, the second rotating gear 19 and the fluid valve body 4, the impurity cleaning effect on the inner wall of the fluid valve body 4 is better. Then, the transmission mechanism 38 is also driven to rotate through the rotating shaft 9, and then the fan body 40 is driven to rotate through the transmission mechanism 38. When the fan body 40 rotates, the debris generated on the inner wall of the fluid valve body 4 can be cleaned, so that the cleaning speed of the rubber scraper 21 becomes faster during scraping. The position of the transmission mechanism 38 is limited by the second limiting frame 39. The transmission mechanism 38 is composed of two sets of limiting rollers and belts.

[0035] The mounting ring 12 is mounted on the upper end surface of the stabilizing block 11. The upper and lower ends of the mounting ring 12 are both mounted with a grinding sheet 13. A guide groove 14 is provided inside the grinding sheet 13. The outer surface of the rotating shaft 9 is sequentially mounted with a gear body 15 and a fixing ring 16 from left to right. The outer surface of the fixing ring 16 is mounted with a mounting bearing 17. The back of the gear body 15 is meshedly connected with a first rotating gear 18. The front surface of the gear body 15 is meshedly connected with a second rotating gear 19. A rotating block 20 is provided on the left side surface of the second rotating gear 19. A rubber scraper 21 is provided on the front surface of the rotating block 20. A connecting frame 22 is installed on the front and rear ends of the mounting bearing 17. The left side of the connecting frame 22 is movably connected with the right side of the second rotating gear 19. The connecting frame The left side surface of 22 is provided with a resistance rod 23. When the rotating shaft 9 is subsequently contracted by the cylinder body 6, the inner and outer surfaces of the fluid valve body 4 can be polished again by the polishing sheet 13, the first polishing arc sheet 26 and the second polishing arc sheet 29. At the same time, the debris after polishing the inner wall of the fluid valve body 4 will also be cleaned up. The debris on the outer surface of the fluid valve body 4 can be scraped off by the rotation of the fluid valve body 4 and the movement of the first polishing arc sheet 26 and the second polishing arc sheet 29. The fluid valve body 4 is inserted and installed in the interior of the support frame 3. Then the outer surface of the support frame 3 will be in resistance through the four sets of fixing blocks 35 and the installation resistance columns 36. Therefore, the fluid valve body 4 can be stably installed between the rotating disk 34, and the overall fluid valve body The installation effect is relatively stable. Then, by starting the cylinder body 6, the connecting ring 7 can be driven to move to the left through the cylinder body 6, and then the forward and reverse motor body 8 inside the connecting ring 7 is started, and then the forward and reverse motor body 8 will drive the rotating shaft 9 to rotate, and then the rotating shaft 9 will drive the stabilizing ring 10 and the stabilizing block 11 to rotate, and then the stabilizing block 11 will drive the installation ring 12 and the grinding sheet 13 to rotate, and then the grinding sheet 13 will rotate inside the operating table 1, and at this time, the outer surface of the grinding sheet 13 can contact the inner wall of the fluid valve body 4, and the inner wall of the fluid valve body 4 is ground by the grinding sheet 13. At this time, the grinding sheet 13 will also follow the cylinder body 6 to move slowly to the left, so the grinding sheet 13 can move to the left at this time. The inner wall of the fluid valve body 4 is polished while moving sideways. The polishing sheet 13 can always polish the inner wall of the fluid valve body 4, which solves the problem of displacement when the polishing belt is used for polishing and contacts with the inner wall of the fluid valve body 4. The polished debris can be guided by the guide groove 14 to avoid the debris being stuck between the polishing sheet 13 and the fluid valve body 4. At the same time, the rotating shaft 9 will also drive the gear body 15 to rotate, and then the gear body 15 will mesh with the second rotating gear 19 and the first rotating gear 18 respectively. Then, the left side surfaces of the second rotating gear 19 and the first rotating gear 18 are both provided with a rotating block 20, and the rotating block 20 is driven to rotate by the second rotating gear 19. If the gear body 15 is rotating forward,At this time, the second rotating gear 19 reverses, and then the second rotating gear 19 drives the rotating block 20 to reverse, and then the rotating block 20 drives the rubber scraper 21 to scrape the inner wall of the fluid valve body 4, and some debris on the inner wall of the polished fluid valve body 4 is scraped off by the rubber scraper 21, and the overall scraping effect is relatively good, avoiding the need to clean the debris on the inner wall of the fluid valve body 4 separately later. At the same time, the material of the rubber scraper 21 is relatively soft. When the rubber scraper 21 contacts the resistance rod 23, the resistance rod 23 bends the rubber scraper 21, so that after the rubber scraper 21 is separated from the surface of the resistance rod 23, the rubber scraper 2 1 will rebound quickly, so that the debris on the surface of the rubber scraper 21 will also quickly fall off the surface of the rubber scraper 21, and the overall cleaning effect is good. Similarly, the first rotating gear 18 can also complete the same operation of the second rotating gear 19, and can clean the inner wall of the fluid valve body 4 as a whole. The fixing ring 16 and the rotating shaft 9 are fixedly installed. At this time, the mounting bearing 17 is movably installed on the outer surface of the fixing ring 16. Therefore, when the rotating shaft 9 rotates, it will not drive the mounting bearing 17 to rotate as a whole. At this time, the mounting bearing 17 rotates through the meshing of the gear body 15 with the first rotating gear 18 and the second rotating gear 19.

[0036] Working principle: when the staff uses the device, first connect the device to an external power supply to provide power support for the device. When in use, first insert the fluid valve body 4 into the interior of the support frame 3, and then the outer surface of the support frame 3 will be in contact with the four sets of fixing blocks 35 and the installation contact columns 36, so that the fluid valve body 4 can be stably installed between the rotating disk 34, and the overall installation effect of the fluid valve body 4 is relatively stable. Then, by starting the cylinder body 6, the cylinder body 6 can drive the connecting ring 7 to move to the left, and then start the forward and reverse motor body 8 inside the connecting ring 7, and then the forward and reverse electric The machine body 8 will drive the rotating shaft 9 to rotate, and then the rotating shaft 9 will drive the stabilizing ring 10 and the stabilizing block 11 to rotate, and then the stabilizing block 11 will drive the mounting ring 12 and the grinding sheet 13 to rotate, and then the grinding sheet 13 will rotate inside the operating table 1, and at this time, the outer surface of the grinding sheet 13 can contact the inner wall of the fluid valve body 4, and the inner wall of the fluid valve body 4 is ground by the grinding sheet 13. At this time, the grinding sheet 13 will also follow the cylinder body 6 to move slowly to the left, so the grinding sheet 13 can move to the left at this time while grinding the inner wall of the fluid valve body 4, and the grinding sheet 13 can be used to grind the inner wall of the fluid valve body 4. 3 can always be polished with the inner wall of the fluid valve body 4, and the polished debris can be guided by the operation of the guide groove 14. At the same time, the rotating shaft 9 will also drive the gear body 15 to rotate, and then the gear body 15 is respectively meshed with the second rotating gear 19 and the first rotating gear 18, and then the left surfaces of the second rotating gear 19 and the first rotating gear 18 are both provided with a rotating block 20, and the rotating block 20 is driven to rotate by the second rotating gear 19. If the gear body 15 is forward, the second rotating gear 19 is reversed, and then the second rotating gear 19 drives the rotating block 20 to reverse, and then the rotating block 20 The rubber scraper 21 will be driven to scrape the inner wall of the fluid valve body 4, and some debris on the inner wall of the polished fluid valve body 4 will be scraped off by the rubber scraper 21. At the same time, the material of the rubber scraper 21 is relatively soft. When the rubber scraper 21 hits the resistance rod 23, the resistance rod 23 will bend the rubber scraper 21. After the rubber scraper 21 is separated from the surface of the resistance rod 23, the rubber scraper 21 will rebound quickly, so that the debris on the surface of the rubber scraper 21 will also quickly separate from the surface of the rubber scraper 21, and the overall cleaning effect is better. Similarly, the first rotating gear 18 can also complete the same operation of the second rotating gear 19.

[0037] When the cylinder body 6 moves to the left, the cylinder body 6 will drive the L-shaped support plate 24 to move to the left, and then the L-shaped support plate 24 will drive the base body 25 to move to the left. At this time, the back of the first polished arc piece 26 will contact the front surface of the fluid valve body 4. When the first polished arc piece 26 moves, the first polished arc piece 26 will drive the mounting frame 27 and the connecting column 28 to move. At this time, the back of the second polished arc piece 29 will also contact the front surface of the fluid valve body 4, and the first polished arc piece 26 and the second polished arc piece 29 are both provided with two groups, and then the two groups of the first polished arc piece 26 and the second polished arc piece 29 can always contact the fluid valve body. 4 is grinded against the front and rear surfaces thereof, and the first grinding arc piece 26 and the second grinding arc piece 29 slide in the inside of the slide groove 42 through the limit slider 41 when moving, so that the first grinding arc piece 26 and the second grinding arc piece 29 have good overall stability when moving. Through the above operation, the inner and outer surfaces of the fluid valve body 4 can be grinded at the same time, and the grinding piece is in stable contact with the inner and outer walls of the fluid valve body 4 during grinding. Then, the rotating shaft 9 will also drive the rotating column 30 to rotate. When the rotating column 30 rotates, the rotating column 30 will drive the protrusion 31 to rotate. At this time, the protrusion 31 is installed in the groove 33, so that the rotating column 30 will drive the rotating cylinder 32 to rotate, and then the rotating cylinder 32 will drive the rotating disk 34 to rotate, and the overall connection between the rotating disk 34 and the fluid valve body 4 is relatively stable, so the rotating disk 34 can drive the fluid valve body 4 to rotate through the fixing block 35 and the mounting abutment column 36, and at the same time, the rotating column 30 can also telescope and slide inside the rotating cylinder 32 through the adaptation of the protrusion 31 and the groove 33, and the forward and reverse motor body 8 can rotate forward and reverse, and the cylinder body 6 can also telescope, and the fluid valve body 4 can rotate forward 180 degrees and then reverse 180 degrees during grinding, so that after the fluid valve body 4 rotates, the grinding efficiency is higher when it is polished by the grinding sheet 13, the first grinding arc sheet 26 and the second grinding arc sheet 29, and the grinding area is relatively complete Similarly, when the forward and reverse motor body 8 rotates forward and reverse, the gear body 15 will also rotate forward and reverse, so that the rotation direction of the first rotating gear 18 and the second rotating gear 19 will also change. Through the change of the rotation direction of the first rotating gear 18, the second rotating gear 19 and the fluid valve body 4, the transmission mechanism 38 will be driven to rotate through the rotating shaft 9, and then the fan body 40 will be driven to rotate through the transmission mechanism 38. When the fan body 40 rotates, the debris generated on the inner wall of the fluid valve body 4 can be cleaned, so that the cleaning speed of the rubber scraper 21 becomes faster during scraping, and the position of the transmission mechanism 38 is limited by the second limiting frame 39. The above is all the working principles of the present invention.
