Description

Technical Field

[0001] This utility model relates to the field of valve plate manufacturing technology, and in particular to a polishing device for the production of dual-valve plates. Background Technology

[0002] As a core component of fluid control systems, dual-valve plates are mainly used in petrochemical, power energy, and water supply and drainage fields. By controlling the opening and closing of the dual valves, precise regulation and cut-off of fluids can be achieved. Its unique dual-valve structure design can not only effectively improve the stability and sealing of fluid control, but also reduce the risk of media leakage. It plays a key role in ensuring the safe operation of the system and improving industrial production efficiency.

[0003] To meet the high-precision surface quality requirements of dual-valve plates, polishing devices have emerged. Through mechanical grinding, chemical polishing, or electrolytic polishing processes, the surface of the valve plate is finely treated to eliminate machining marks and reduce surface roughness, thereby improving the sealing performance and corrosion resistance of the valve plate. The performance of the polishing device directly determines the finished quality of the dual-valve plate and is of great significance for extending the service life of the equipment and reducing maintenance costs.

[0004] However, existing dual-valve plate polishing devices use a fixed polishing head in conjunction with linear reciprocating motion. Material removal is achieved through the relative movement between the polishing head and the valve plate surface, which can ensure the flatness and surface smoothness of the valve plate. However, the polishing head is prone to wear after long-term operation, and its pressure distribution is uneven. It cannot be adjusted according to the different sizes of the valve plate, resulting in different polishing effects in different areas of the valve plate surface. Utility Model Content

[0011] As a further description of the above technical solution:

[0012] The outer walls of the two fixed disks are equidistantly connected by fixing bolts, and one end of each fixing bolt passes through the fixed disk and the corresponding slot in sequence.

[0013] As a further description of the above technical solution:

[0022] 1. In this utility model, a motor drives a threaded rod to rotate, which in turn causes the threaded rod to rotate synchronously via rollers and a transmission belt. This drives the moving block to slide in the moving groove, causing the support frame to move laterally. At the same time, a telescopic rod extends and retracts within the sliding groove to adjust the position of the sliding block. The hydraulic rod extends to bring the polishing blade closer to the valve plate. The motor drives a rotating rod to rotate the polishing blade, thus realizing the adjustment of the position and spacing of the polishing components.

In this utility model, the telescopic rod 2 extends and retracts within the sliding groove 2, pushing the column to slide on the top of the U-shaped plate to the fixed point that matches the valve plate. The telescopic rod 2 provides support to maintain the stability of the column position. Then, the threaded column is rotated, and the fixed rod moves down in the groove using threaded transmission, applying downward pressure to the valve plate and pressing it tightly onto the worktable. This allows for flexible adjustment of the fixed point according to the valve plate size. The threaded transmission provides stable pressure, ensuring that the valve plate remains stable during the polishing process, effectively improving polishing accuracy and quality.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a polishing device for producing dual-valve plates, comprising a worktable 1. A U-shaped plate 3 is fixedly connected to the top of the worktable 1, providing mounting support for the fixing mechanism 2 and the moving component. A moving component is provided on the right side of the worktable 1 to adapt to polishing requirements at different positions. A support frame 10 is provided on the top of the moving component to install and support the polishing blade 18, providing a stable structural frame for the polishing operation. A sliding groove 11 is provided on the inner top of the support frame 10, providing a sliding track for the telescopic rod 12 and the sliding block 13, facilitating adjustment of the lateral spacing of the polishing blade 18. The telescopic rod 12 is fixedly connected to both the front and rear sides of the sliding groove 11, and the telescopic movement drives the sliding block 13 to move within the sliding groove 11. The internal movement allows for precise adjustment of the lateral position of the polishing blade 18. Sliding blocks 13 are fixedly connected to adjacent ends of the two telescopic rods 12, connecting the telescopic rods 12 and hydraulic rods 14, transmitting the movement of the telescopic rods 12. Hydraulic rods 14 are fixedly connected to the bottoms of the two sliding blocks 13, allowing the polishing blade 18 to rise and fall through telescopic movement. Connecting blocks 15 are fixedly connected to the bottoms of the two hydraulic rods 14, used to mount motor 16 and rotating rod 17. Motor 16 is fixedly connected to the opposite sides of the two connecting blocks 15, providing rotational power to the rotating rod 17 and the polishing blade 18. The output ends of the two motors 16 pass through the connecting blocks 15 and are fixedly connected to the rotating rod 17, transmitting the power of the motors 16 and driving the polishing blade 18 to rotate. Polishing blades 18 are fixedly connected to the outer walls of each of the two rotating rods 17, directly acting on the surface of the dual-valve plate for polishing. A disc 19 is fixedly connected to each adjacent end of each of the two rotating rods 17, cooperating with a fixed disc 22 for easy and quick replacement of polishing blades 18 of different specifications. Multiple slots 20 are provided on adjacent sides of each of the two discs 19, cooperating with inserts 23 on the fixed disc 22 to achieve quick connection and disassembly of the rotating rods 17 and the fixed disc 22. A rotating rod 21 is rotatably connected to the inner side of each of the two connecting blocks 15, allowing the fixed disc 22 to rotate, facilitating the connection and separation of the inserts 23 and slots 20. A fixed disc 22 is fixedly connected to one side of each of the two rotating rods 21, and the rotating rods 17 are fixed by the engagement of the inserts 23 with the slots 20 on the discs 19. To ensure the polishing blade 18 is securely installed, multiple inserts 23 are fixedly connected to one side of each of the two fixed discs 22, which are inserted into the slots 20 of the disc 19 to achieve quick positioning and fixation of the rotating rod 17 and the fixed disc 22. A fixing mechanism 2 is provided on the top of the worktable 1 to fix the valve plate and prevent it from shifting during polishing, thus ensuring polishing accuracy. The fixing mechanism 2 is used to fix the valve plate and ensure its stability during polishing. The moving component includes a conveyor belt 4 and a transmission belt 9. The conveyor belt 4 assists in transporting the valve plate, and the transmission belt 9 is used to transmit power to achieve synchronous rotation of the threaded rod 6 and the threaded rod 7. The front and rear sides of the conveyor belt 4 are fixedly connected to the front and rear sides of the interior of the U-shaped plate 3 to strengthen the structural strength of the moving component and ensure its operational stability.The top and front and rear sides of the workbench 1 are provided with moving slots 25. A motor 5 is fixedly connected to the rear right side of the workbench 1 to provide power to the moving components and drive the threaded rod 6 and the threaded rod 7 to rotate. The output end of the motor 5 passes through the rear moving slot 25 and is fixedly connected to the threaded rod 6, which drives the moving block 26 to move. The threaded rod 7 is rotatably connected inside the front moving slot 25 and cooperates with the threaded rod 6. Synchronous rotation is achieved through the transmission belt 9 to ensure the smooth movement of the support frame 10. The left ends of the threaded rod 6 and the threaded rod 7 both pass through the moving slot 25. Rollers 8 are fixedly connected to the support frame 10. Through the cooperation of rollers 8 and a transmission belt 9, power transmission between threaded rod 6 and threaded rod 7 is achieved. The outer walls of the two rollers 8 are connected by the transmission belt 9 to ensure the synchronous rotation of threaded rod 6 and threaded rod 7, making the movement of the support frame 10 more stable. Moving blocks 26 are threadedly connected to the outer walls of both threaded rods 6 and 7. The tops of both moving blocks 26 are fixedly connected to the bottom of the support frame 10, so that the movement of the moving blocks 26 can drive the support frame 10 to move synchronously, realizing the position adjustment of the polishing assembly.

[0033] Specifically, starting motor 5 drives threaded rod 6 to rotate. Through the cooperation of roller 8 and transmission belt 9, threaded rod 7 rotates synchronously, driving moving block 26, which is threadedly connected to threaded rod 6 and threaded rod 7, to move within moving groove 25. This causes support frame 10 to move laterally along worktable 1, adjusting the polishing assembly above the valve plate to be polished. According to the polishing requirements of the valve plate, the telescopic rod 12 extends and retracts within sliding groove 11, causing sliding block 13 to move. The distance between the two hydraulic rods 14 is adjusted, and the hydraulic rods 14 extend, bringing the polishing blade 18 at the bottom of connecting block 15 closer to the valve plate surface. Starting motor 16 drives rotating rod 17 and polishing blade 18 to rotate at high speed to polish the valve plate. When it is necessary to replace polishing blade 18, rotating rod 17 is rotated. 21. Disconnect the insert 23 on the fixed plate 22 from the slot 20 of the disc 19 to remove the polishing knife 18. After replacement, rotate the rotating rod 21 in the opposite direction to reinsert the insert 23 into the slot 20. The connection is further reinforced by passing the fixing bolt 24 through the fixed plate 22 and the slot 20. During the entire polishing process, the sliding groove 28 inside the support frame 10 cooperates with the slider 29 to ensure the smooth movement of the sliding block 13. The limiting groove 31 on the top of the worktable 1 cooperates with the limiting block 32 to prevent the moving block 26 from shifting. The washer 30 on the fixing bolt 24 ensures the stability of the connection. The operation of the motor 5, telescopic rod 12, hydraulic rod 14, motor 16 and telescopic rod 203 can be centrally controlled through the switch 27 on the front of the worktable 1 to realize the automated control of the polishing operation.

[0034] Reference Figure 2 and Figure 5The fixing mechanism 2 includes multiple columns 201, which can be used to fix the valve plates of the double valves to be processed. The bottoms of the multiple columns 201 are slidably connected to the front and rear sides of the top of the U-shaped plate 3, allowing the columns 201 to move flexibly on the U-shaped plate 3 to adapt to the fixing requirements of valve plates of different sizes. The front and rear sides of the top of the U-shaped plate 3 are provided with sliding grooves 202, which provide tracks for the sliding of the columns 201 and ensure the stability of the movement of the columns 201. The left and right sides of the interior of the multiple sliding grooves 202 are fixedly connected with telescopic rods 203. The extension and retraction of the telescopic rods 203 can drive the columns 201 to move within the sliding grooves 202, realizing the automatic adjustment of the position of the columns 201. One end of the multiple telescopic rods 203 is fixedly connected to one side of the corresponding column 201, so that the telescopic rods 203 can precisely control the movement of each column 201. The top side of the multiple columns 201 is provided with a groove. 204 provides space for the movement of the fixed rod 206, allowing the fixed rod 206 to rise and fall vertically within the groove 204. The tops of multiple columns 201 are rotatably connected to threaded columns 205. By rotating the threaded columns 205, the rotational motion can be converted into linear motion, driving the fixed rod 206 to move up and down. The bottom ends of multiple threaded columns 205 pass through the groove 204 and are threadedly connected to the corresponding fixed rod 206, achieving precise control of the rise and fall of the fixed rod 206, thereby firmly clamping the valve plate to be processed. A switch 27 is fixedly connected to the front right end of the worktable 1, providing the operator with an interface for centralized control of the various components of the device, allowing for convenient and quick start or stop of the equipment. The switch 27 is electrically connected to motor 5, telescopic rod 12, hydraulic rod 14, motor 16, and telescopic rod 203, respectively. Through the switch 27, the coordinated work of multiple power components can be controlled synchronously, realizing the automated operation of the polishing device.

[0035] Specifically, when using this polishing device, firstly, activate the telescopic rod 203 via switch 27. This rod is fixed to the left and right sides of the sliding groove 202 at the top of the U-shaped plate 3, pushing the column 201 to slide within the sliding groove 202. Adjust the positions of the multiple columns 201 on the front and rear sides of the top of the U-shaped plate 3 according to the size and shape of the double-valve plate to be polished, ensuring the columns 201 are distributed at appropriate fixing points on the valve plate. Once the positions of the columns 201 are determined, place the valve plate on the corresponding position on the worktable 1, ensuring the edge of the valve plate is directly below the groove 204 at the top of the column 201. The operator then manually rotates the top of the column 201... The threaded post 205 is threadedly connected to the fixed rod 206, and the fixed rod 206 cannot rotate due to the limiting effect of the groove 204. As the threaded post 205 rotates, the fixed rod 206 moves vertically downward in the groove 204. When the bottom of the fixed rod 206 contacts the surface of the valve plate, the threaded post 205 continues to rotate, so that the fixed rod 206 applies continuously increasing pressure to the valve plate until the valve plate is firmly pressed onto the worktable 1. Through the coordinated action of the fixed rods 206 on the multiple posts 201, the valve plate is fixed from different positions to ensure that the valve plate will not shift or shake during the polishing process.

[0036] Reference Figure 1 , Figure 4 and Figure 5 Two fixed discs 22 are equidistantly rotatably connected to their outer walls by fixing bolts 24. Rotating these bolts secures the fixed discs 22 to the disc 19, ensuring the polishing blade 18 does not loosen during operation. One end of each fixing bolt 24 passes through the fixed disc 22 and its corresponding slot 20, enhancing the stability of the connection between the fixed disc 22 and the disc 19 and preventing the polishing blade 18 from falling off during high-speed rotation. The support frame 10 has grooves 28 on both its left and right sides, providing a track for the sliding block 29, allowing the sliding block 13 to move smoothly horizontally within the support frame 10. Sliding blocks 29 are fixedly connected to the left and right sides of each sliding block 13, cooperating with the grooves 28 to guide and limit the movement of the sliding block 13, ensuring the smooth operation of the polishing assembly. To improve the accuracy of the lateral movement of the component, multiple fixing bolts 24 are slidably connected to the outer walls of the fixing bolts 24, which can increase the contact area between the fixing bolts 24 and the fixing plate 22, making the pressure distribution more uniform. One side of each of the multiple fixing bolts 30 is in contact with the outer wall of the corresponding fixing plate 22, which can effectively prevent the fixing bolts 24 from directly contacting the fixing plate 22 and causing surface damage, while also playing a role in preventing loosening and damping. Limiting grooves 31 are opened on the front and rear sides of the top of the worktable 1 to provide a moving track for the limiting block 32 and limit the movement range of the moving block 26. The front and rear sides of the two moving blocks 26 are fixedly connected to the limiting block 32, which cooperates with the limiting groove 31 to prevent the moving block 26 from deviating or disengaging from the threaded rod during movement, thus ensuring the stability of the movement of the support frame 10.

[0037] Specifically, by tightening the fixing bolt 24, the relative movement between the disc 19 and the fixed disc 22 is restricted, ensuring that the rotating rod 17 and the polishing knife 18 will not loosen during high-speed rotating polishing operations, and ensuring that the polishing knife 18 works stably. When the telescopic rod 12 drives the sliding block 13 to move horizontally to adjust the lateral spacing of the polishing components, the slider 29 slides along the slide groove 28 to ensure that the sliding block 13 moves smoothly and prevents it from deviating or shaking during the movement. During the tightening of the fixing bolt 24, the shim 30 increases the contact area between the fixing bolt 24 and the fixed disc 22, so that the pressure is evenly distributed and the fixing bolt 24 does not directly act on the surface of the fixed disc 22, causing local damage. When the moving block 26 moves laterally with the rotation of the threaded rod 6 and the threaded rod 7, the limiting block 32 slides in the limiting groove 31 to restrict and guide the movement trajectory of the moving block 26, preventing the moving block 26 from shifting laterally or detaching from the threaded rod during the movement.

[0038] Working principle: The double valve plate to be polished is placed on the worktable 1. The motor 5 is started, and its output end drives the threaded rod 6 to rotate. At the same time, through the cooperation of the roller 8 and the transmission belt 9, the threaded rod 7 rotates synchronously, which in turn drives the moving block 26, which is threadedly connected to the threaded rod 6 and the threaded rod 7, to move in the moving groove 25. This allows the support frame 10 to move laterally along the worktable 1, adjusting the polishing assembly installed on the support frame 10 to the appropriate position. Through the extension and retraction of the telescopic rod 12 in the sliding groove 11, the sliding block 13 moves horizontally, thereby adjusting the lateral distance between the two hydraulic rods 14 to accommodate valve plates of different sizes. After adjustment, the hydraulic rods 14 extend, driving the connecting block 15 and the motor 16 on it. The rotating rod 17 and polishing knife 18 move down, bringing the polishing knife 18 close to the valve plate surface. The motor 2 16 is started, and its output end drives the rotating rod 17 to rotate, which in turn drives the polishing knife 18 to rotate at high speed to polish the valve plate. When it is necessary to replace the polishing knife 18 with a different specification, the rotating rod 21 can be rotated in the connecting block 15, so that the insert 23 on the fixed plate 22 is disengaged from the slot 20 on the disc 19. The rotating rod 17 and polishing knife 18 can then be disassembled. After the replacement is completed, the operation is reversed, and the insert 23 is inserted into the corresponding slot 20 to quickly fix the polishing knife 18. During the entire polishing process, the U-shaped plate 3 provides stable support for the moving components, and the conveyor belt 4 can assist in transporting the valve plate. Through the coordinated operation between the components, the polishing work of the dual valve plate is completed efficiently.

[0039] Furthermore, based on the size and fixing requirements of the valve plate, the position of the column 201 on the front and rear sides of the top of the U-shaped plate 3 is adjusted by the extension and retraction of the telescopic rod 203 within the sliding groove 202. The telescopic rod 203 pushes or pulls the column 201 to slide within the sliding groove 202 to adapt to the fixing points of valve plates of different specifications. After the position is determined, the telescopic rod 203 provides a certain supporting force to maintain the stability of the column 201. The double valve plate to be polished is placed on the corresponding position on the worktable 1, so that the edge of the valve plate is above the groove 204 at the top of the column 201. Then, the threaded column 205 is rotated. Since the threaded column 205 is threadedly connected to the fixing rod 206, as the threaded column 205 rotates, the fixing rod 206 gradually moves down within the groove 204. When the bottom of the fixing rod 206 contacts the surface of the valve plate, the threaded column 205 is rotated again. Using the principle of threaded transmission, the fixing rod 206 applies downward pressure to the valve plate, pressing the valve plate tightly onto the worktable 1.
