Description

Technical Field

[0001] This utility model belongs to the technical field of ceramic valve ball processing, and particularly relates to a fixing device for ceramic valve ball processing. Background Technology

[0002] Ceramic valve balls are valves made from high-tech new ceramic structural materials. They are characterized by wear resistance, corrosion resistance, and ultra-long service life. Ceramic valve balls are typically categorized into small valve balls (15mm-50mm), medium valve balls (50mm-200mm), and large valve balls (over 200mm). The manufacturing process of ceramic valve balls usually includes pressing, calcination, drilling, grinding, cleaning, and testing. The finished ceramic valve balls are generally used to assemble ceramic valves with other components.

[0003] For example, Chinese patent CN209737354U discloses a fixing device for machining ceramic valve balls, including a mandrel, an elastic sleeve, a circular inclined block, and a locking block. The elastic sleeve has expansion inclined plates at both ends of its central hole. The circular inclined blocks are respectively disposed at both ends of the elastic sleeve and are adapted to the expansion inclined plates. The device also includes a rotator located between the locking block and the circular inclined block. The rotator includes a first rotating component, a second rotating component, at least four balls, a left nut, a right nut, and a sleeve. The end face of the first rotating component has a first ball raceway.

[0004] The aforementioned patent has the following problems:

[0005] This patent has several drawbacks in its use. For example, when grinding the surface of a large ceramic valve ball after drilling, the aforementioned device, after fixing the large ceramic valve ball, allows the worker to grind only one side of the ball. To grind the other side, the worker must remove the ceramic valve ball from the device, flip it so that the other side faces outwards, and then fix it back in the device before grinding the other side. This process is cumbersome, time-consuming, and labor-intensive. Furthermore, during the grinding of large ceramic valve balls, workers need to manually apply grinding fluid. Since the grinding equipment is motor-driven and continuously running, workers may experience hand injuries or cuts due to inattention while applying the grinding fluid, posing a safety hazard. Therefore, we propose a fixing device for processing ceramic valve balls. Utility Model Content

[0006] The purpose of this invention is to provide a fixing device for processing ceramic valve balls, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a fixing device for machining ceramic valve balls, including a platform, and further comprising:

[0008] A sludge collection tank is located on the top of the platform. A support plate is fixedly installed on one side of the sludge collection tank and on the top of the platform. A rotating roller that passes through the support plate is rotatably installed on the support plate. A transmission wheel and a limiting disc are coaxially installed at both ends of the rotating roller.

[0009] Telescopic rod one, which is fixedly installed on one side of the limiting plate, and telescopic rod two is sleeved on the telescopic rod one. Several support plates are provided around the telescopic rod two, and a rubber pad is fixedly installed on one side of the support plate.

[0010] A control component, located on a platform, is used to control several support plates to move away from or towards the telescopic rod 2;

[0011] A water tank is fixedly installed on the top of the platform and on one side of the support plate. A water pump is fixedly installed on the top of the water tank. A flexible metal pipe is threaded onto the outlet end of the water pump, and several nozzles are provided on the flexible metal pipe.

[0012] Support plate two, the support plate two is fixedly installed on one side of the platform, and a sliding groove two is opened on one side of the support plate two. A sliding plate is slidably installed in the sliding groove two. A motor one and a grinding brush are respectively provided on the upper and lower sides of the sliding plate.

[0013] A power assembly located on the platform is used to drive the transmission wheel to rotate slowly and to drive the slide plate to slide up and down in the slide groove.

[0014] In this technical solution, through the set control components, when it is necessary to grind the surface of the large ceramic valve ball after drilling, the worker first puts the large ceramic valve ball after drilling onto several support plates, and then the control components drive the support plates to gradually move away from the telescopic rod two, so that the support plates press against the inner wall of the ceramic valve ball after drilling until the rubber pads on the support plates press against the inner wall of the ceramic valve ball after drilling and deform. Then the drive control components are stopped, and finally the ceramic valve ball is fixed in the overall device. This process ensures that the ceramic valve ball can be fixed in the overall device.

[0015] Then, grinding fluid is injected into the water tank, and the water pump delivers the grinding fluid from the water tank to the flexible metal tube. Under the action of water pressure, several nozzles on the flexible metal tube spray the grinding fluid evenly onto the surface of the ceramic valve ball. This eliminates the need for workers to manually apply the grinding fluid, avoiding the risk of workers' hands being scratched by the grinding brush and ensuring the personal safety of the workers.

[0016] Then, through the set power component, the power component drives the grinding brush to move downward, so that the bottom of the grinding brush covers the surface of the ceramic valve ball. Then, the power component is controlled to ensure that the ceramic valve ball can slowly rotate in the whole device with the cooperation of the limit plate, telescopic rod two, connecting block, support plate and limit block. Then, the power of motor one is turned on and started. The output shaft of motor one drives the grinding brush to rotate, so that the grinding brush can continuously grind the surface of the ceramic valve ball. This process ensures that the surface of the large ceramic valve ball can be continuously ground in the whole device, avoiding the repetitive operation of workers needing to remove, flip and reinstall the ceramic valve ball, reducing the workload of workers and saving time and effort.

[0017] In the above technical solution, the control component further includes:

[0018] A plurality of limiting grooves are provided on the limiting plate, and one end of a plurality of support plates passes through the plurality of limiting grooves and is fixedly installed with limiting blocks. Two connecting blocks that are rotatably connected to the second telescopic rod are rotatably installed on the support plates. The second telescopic rod is provided with a telescopic groove, and the first telescopic rod is located in the telescopic groove. A spring that is fixed to one end of the first telescopic rod is fixedly installed on the inner wall of the telescopic groove. A bolt is fixedly installed at one end of the second telescopic rod.

[0019] The hydraulic cylinder is fixed to the top of the platform by several bolts. A connecting roller is rotatably mounted on the output shaft of the hydraulic cylinder. One end of the connecting roller has a slot, and the slot is engaged with a bolt.

[0020] In this technical solution, when it is necessary to fix the ceramic valve ball, the large ceramic valve ball after drilling is first placed on several support plates. Then, the hydraulic cylinder is powered on and started. The output shaft of the hydraulic cylinder drives the connecting roller to move towards the support plate one, so that the groove on the connecting roller gradually approaches the bolt and is inserted into the bolt. Subsequently, the output shaft of the hydraulic cylinder continues to press the telescopic rod two through the connecting roller, so that the telescopic rod two slides towards the limiting plate on the telescopic rod one. At the same time, the spring in the telescopic groove begins to contract and generate elastic force under the pressure of the telescopic rod one. Under the action of pressure, the telescopic rod two drives several connecting blocks to rotate, and through the several connecting blocks, it presses the corresponding support plate away from the telescopic rod two. At the same time, the several support plates drive the corresponding limiting blocks to slide in the corresponding limiting grooves and away from the telescopic rod one, so that the several support plates press the inner wall of the drilled ceramic valve ball until the rubber pads on the several support plates press the inner wall of the drilled ceramic valve ball and deform. Then, the hydraulic cylinder is closed. At this time, the ceramic valve ball can be fixed in the overall device. This process ensures that the ceramic valve ball can be fixed in the overall device.

[0021] In the above technical solution, the limiting grooves are distributed in a ring with equal spacing, one end of the support plate is slidably connected to the limiting grooves, the first telescopic rod is slidably connected to the telescopic groove, the center of the second telescopic rod and the connecting roller are both located on the same horizontal plane as the center point of the bolt cross section, and the bolt and the groove are equal in size.

[0022] In this technical solution, it is ensured that the support plates on the limiting grooves are evenly distributed on the inner wall of the large ceramic valve ball, ensuring that the support plates can slide normally in the limiting grooves, ensuring that the second telescopic rod can slide normally on the first telescopic rod, ensuring that the first telescopic rod, the second telescopic rod, the bolt and the connecting roller can rotate on the same concentric circle, and ensuring that the bolt and the slot can be properly inserted together.

[0023] In the above technical solution, the power component further includes:

[0024] Motor 2 is located on the top of the platform and on one side of transmission wheel 1. The output shaft of motor 2 is fixedly mounted with transmission wheel 2, and a belt is installed between transmission wheel 2 and transmission wheel 1 for transmission.

[0025] A transmission groove is formed at the bottom of the slide groove two and located inside the support plate two. A gear two is rotatably installed inside the transmission groove, and one end of the gear two passes through the inner wall of the transmission groove and is fixedly installed with a handle.

[0026] Gear 1 is meshed on top of gear 2 and located in the transmission groove. A threaded rod is fixedly installed on the top of gear 1, and the upper end of the threaded rod extends into the slide groove 2 and passes through the slide plate.

[0027] In this technical solution, after the ceramic valve ball is fixed, the worker turns the handle by hand, which drives the second gear to rotate. Under the action of meshing, the second gear drives the first gear to rotate in the transmission groove, and the first gear drives the threaded rod to rotate in the second slide groove. Under the action of the thread, the threaded rod drives the slide plate to slide downward in the second slide groove. The slide plate also drives the first motor and the grinding brush to move down until the diamond brushes on the bottom of the grinding brush are completely in contact with the surface of the ceramic valve ball. Then the worker stops turning the handle. This process ensures that the large ceramic valve ball can be ground by the whole device.

[0028] Simultaneously, the second motor is powered on and started. The output shaft of the second motor drives the second transmission wheel to rotate slowly. The second transmission wheel drives the first transmission wheel to rotate via a belt. The first transmission wheel drives the limiting disc to rotate slowly on the support plate via a rotating roller. At the same time, the limiting disc drives the first telescopic rod to rotate. Under the action of compression, the limiting disc drives several support plates to rotate through the cooperation of the limiting block and the limiting groove. The several support plates drive the second telescopic rod to rotate through the corresponding connecting blocks. At the same time, the second telescopic rod drives the connecting roller to rotate slowly on the output shaft of the hydraulic cylinder through the bolt. The several support plates are pressed against the inner wall of the ceramic valve ball by the rubber pad. Under the action of friction, the several support plates drive the ceramic valve ball to rotate slowly, so that the entire large ceramic valve ball rotates within several diamond brushes at the bottom of the grinding brush plate. This allows the surface of the ceramic valve ball to be ground by the grinding brush plate. This process ensures that the entire device can grind all surfaces of the ceramic valve ball without removing it, saving workers' time.

[0029] In the above technical solution, the first gear is rotatably connected to the transmission groove, the threaded rod is rotatably connected to the second slide groove and the transmission groove, and the threaded rod is threadedly connected to the slide plate.

[0030] In this technical solution, it is ensured that gear one can drive the threaded rod to rotate normally in the transmission groove, and that the threaded rod can drive the slide plate to slide up and down in the slide groove two.

[0031] In the above technical solution, the number of support plates is at least 4, and the support plates are distributed in a ring with equal spacing.

[0032] In this technical solution, the overall structure of the device is kept stable, and several support plates are evenly distributed on the inner wall of the large ceramic valve ball, thereby ensuring that the overall device can stably drive the ceramic valve ball to rotate.

[0033] In the above technical solution, the water pump is further provided with a suction pipe fixedly installed at the water inlet end, and the bottom end of the suction pipe passes through the top of the water tank and extends into the water tank. Several nozzles are threadedly connected to flexible metal pipes, and several nozzles are located between one of the support plates and the second support plate.

[0034] In this technical solution, it is ensured that when the water pump is connected to the power supply and started, the water pump can draw out the grinding fluid from the water tank through the suction pipe and spray it onto the surface of the ceramic valve ball through several nozzles on the flexible metal pipe, ensuring that the nozzles will not spray the grinding fluid onto places other than the surface of the ceramic valve ball.

[0035] The beneficial effects of this utility model are:

[0036] 1. This fixing device for processing ceramic valve balls, through the set control components, with the cooperation of the control components, limit plate, telescopic rod one, telescopic rod two and support plate, ensures that large ceramic valve balls can be fixed in the overall device. Then, through the set power components, with the cooperation of the power components, motor one and grinding brush, it ensures that during the grinding of large ceramic valve balls, there is no need for workers to remove the ceramic valve balls from the overall device and flip them over. All surfaces of the ceramic valve balls can be ground, saving time and labor.

[0037] 2. The fixing device for processing ceramic valve balls, through the cooperation of a water pump, a flexible metal pipe and a suction pipe, ensures that during the grinding process of ceramic valve balls, the flexible metal pipe can evenly spray the grinding liquid onto the large ceramic valve balls through several nozzles. Moreover, workers do not need to manually apply the grinding liquid to the ceramic valve balls, thus avoiding the risk of workers' fingers being scratched by the grinding brush when applying the grinding liquid, and ensuring the personal safety of the workers.

[0055] Please see Figures 1-10 As shown, this embodiment provides a fixing device for machining ceramic valve balls, including a platform 1, and further including:

[0056] A sludge collection tank 35 is located on the top of the platform 1. A support plate 2 is fixedly installed on one side of the sludge collection tank 35 and on the top of the platform 1. A rotating roller 3 that passes through the support plate 2 is rotatably installed on the support plate 2. A transmission wheel 32 and a limiting disc 4 are coaxially installed at both ends of the rotating roller 3.

[0057] Telescopic rod 1 5 is fixedly installed on one side of the limiting plate 4. Telescopic rod 2 6 is sleeved on telescopic rod 1 5. Several support plates 9 are provided around the periphery of telescopic rod 2 6. A rubber pad is fixedly installed on one side of the support plate 9.

[0058] A control component is located on platform 1 and is used to control several support plates 9 to move away from or towards the telescopic rod 2 6;

[0059] Water tank 17 is fixedly installed on the top of platform 1 and located on one side of support plate 2. Water pump 18 is fixedly installed on the top of water tank 17. Flexible metal pipe 19 is threadedly installed at the outlet end of water pump 18, and several nozzles are provided on flexible metal pipe 19.

[0060] Support plate 21 is fixedly installed on one side of platform 1. A slide groove 25 is provided on one side of support plate 21. A slide plate 22 is slidably installed in the slide groove 25. A motor 23 and a grinding brush 24 are respectively provided on the upper and lower sides of the slide plate 22.

[0061] The power unit is located on the platform 1 and is used to drive the transmission wheel 32 to rotate slowly and drive the slide plate 22 to slide up and down in the slide groove 25.

[0062] In this system, when the surface of the large ceramic valve ball after drilling needs to be polished, the worker first places the large ceramic valve ball after drilling onto several support plates 9. Then, the control component drives the support plates 9 to gradually move away from the telescopic rod 6, so that the support plates 9 press against the inner wall of the ceramic valve ball after drilling. When the rubber pads on the support plates 9 press against the inner wall of the ceramic valve ball after drilling and deform, the drive control component stops, and the ceramic valve ball is finally fixed in the overall device. This process ensures that the ceramic valve ball can be fixed in the overall device.

[0063] Then, grinding fluid is injected into the water tank 17, and the grinding fluid in the water tank 17 is transported to the flexible metal tube 19 by the water pump 18. Under the action of water pressure, the grinding fluid is evenly sprayed onto the surface of the ceramic valve ball by several nozzles on the flexible metal tube 19. The grinding fluid does not need to be manually applied by the worker, avoiding the worker's hands from being scratched by the grinding brush 24 and ensuring the worker's personal safety.

[0064] Then, through the set power component, the power component drives the grinding brush 24 to move downward, so that the bottom of the grinding brush 24 covers the surface of the ceramic valve ball. Then, the power component is controlled to ensure that the ceramic valve ball can slowly rotate in the whole device with the cooperation of the limit plate 4, the telescopic rod 6, the connecting block 8, the support plate 9 and the limit block 10. Then, the power of the motor 23 is turned on and started. The output shaft of the motor 23 drives the grinding brush 24 to rotate, so that the grinding brush 24 can continuously grind the surface of the ceramic valve ball. This process ensures that the surface of the large ceramic valve ball can be continuously ground in the whole device, avoiding the repetitive operation of workers needing to remove, flip and reinstall the ceramic valve ball, reducing the workload of workers and saving time and effort. Example

[0065] This embodiment provides a fixing device for machining ceramic valve balls. In addition to the technical solutions of the above embodiments, it also has the following technical features, and the control components include:

[0066] A number of limiting grooves 11 are provided on the limiting plate 4, and one end of a number of support plates 9 passes through the number of limiting grooves 11 and is fixedly installed with limiting blocks 10. Two connecting blocks 8 are rotatably installed on the support plates 9 and are rotatably connected to the telescopic rod 6. A telescopic groove 12 is provided inside the telescopic rod 6, and the telescopic rod 5 is located inside the telescopic groove 12. A spring 13 fixed to one end of the telescopic rod 5 is fixedly installed on the inner wall of the telescopic groove 12, and a bolt 7 is fixedly installed at one end of the telescopic rod 6.

[0067] The hydraulic cylinder 16 is fixed to the top of the platform 1 by several bolts. A connecting roller 15 is rotatably mounted on the output shaft of the hydraulic cylinder 16. One end of the connecting roller 15 is provided with a slot 14, and the slot 14 is engaged with the bolt 7.

[0068] When it is necessary to fix the ceramic valve ball, firstly, the large ceramic valve ball after drilling is placed on several support plates 9. Then, the hydraulic cylinder 16 is powered on and started. The output shaft of the hydraulic cylinder 16 drives the connecting roller 15 to move towards the support plate 2, so that the slot 14 on the connecting roller 15 gradually approaches the bolt 7 and is inserted into the bolt 7. Then, the output shaft of the hydraulic cylinder 16 continues to press the telescopic rod 6 through the connecting roller 15, so that the telescopic rod 6 slides towards the limiting plate 4 on the telescopic rod 5. At the same time, the spring 13 in the telescopic groove 12 begins to contract under the pressure of the telescopic rod 5 and generates elasticity. Simultaneously, under the action of compression, the telescopic rod 26 drives several connecting blocks 8 to rotate, and through the several connecting blocks 8, it compresses the corresponding support plate 9 away from the telescopic rod 26. At the same time, the several support plates 9 drive the corresponding limiting block 10 to slide in the corresponding limiting groove 11 and move away from the telescopic rod 15, so that the several support plates 9 compress the inner wall of the drilled ceramic valve ball until the rubber pad on the several support plates 9 compresses the inner wall of the drilled ceramic valve ball and deforms. At this time, the hydraulic cylinder 16 is closed. At this time, the ceramic valve ball can be fixed in the overall device. This process ensures that the ceramic valve ball can be fixed in the overall device.

[0069] It is worth noting that one end of the connecting roller 15 is located outside the output shaft of the hydraulic cylinder 16. When the latch 7 is fully inserted into the slot 14, one end of the connecting roller 15 will press against the telescopic rod 2 6, thereby preventing the telescopic rod 2 6 from directly contacting the output shaft of the hydraulic cylinder 16 and preventing the output shaft of the hydraulic cylinder 16 from pressing against the telescopic rod 2 6 and causing a large friction force, which would affect the normal rotation of the telescopic rod 2 6. Example

[0070] This embodiment provides a fixing device for processing ceramic valve balls. In addition to the technical solution of the above embodiment, it also has the following technical features: a plurality of limiting grooves 11 are distributed in a ring at equal intervals; one end of the support plate 9 is slidably connected to the limiting groove 11; the first telescopic rod 5 is slidably connected to the telescopic groove 12; the center of the second telescopic rod 6 and the connecting roller 15 are both located on the same horizontal plane as the center point of the cross section of the bolt 7; and the bolt 7 and the groove 14 are of equal size.

[0071] Among them, it is ensured that the support plates 9 on the limiting grooves 11 can be evenly distributed on the inner wall of the large ceramic valve ball, that the support plates 9 can slide normally in the limiting grooves 11, that the telescopic rod 2 6 can slide normally on the telescopic rod 1 5, that the telescopic rod 1 5, the telescopic rod 2 6, the bolt 7 and the connecting roller 15 can rotate on the same concentric circle, and that the bolt 7 and the slot 14 can be properly inserted together. Example

[0072] This embodiment provides a fixing device for machining ceramic valve balls. In addition to the technical solutions of the above embodiments, it also has the following technical features, including a power component:

[0073] Motor 2 31 is set on the top of platform 1 and located on one side of transmission wheel 1 32. The output shaft of motor 2 31 is fixedly mounted with transmission wheel 2 33. A belt 34 is installed between transmission wheel 2 33 and transmission wheel 1 32.

[0074] The transmission groove 30 is opened at the bottom of the slide groove 25 and located in the support plate 21. A gear 29 is rotatably installed in the transmission groove 30, and one end of the gear 29 passes through the inner wall of the transmission groove 30 and is fixedly installed with a handle 27.

[0075] Gear 1 28 is meshed on the top of gear 29 and located in the transmission groove 30. A threaded rod 26 is fixedly installed on the top of gear 1 28, and the upper end of the threaded rod 26 extends into the slide groove 25 and passes through the slide plate 22.

[0076] In this process, once the ceramic valve ball is fixed, the worker manually rotates handle 27. Handle 27 drives gear 29 to rotate. Under the action of meshing, gear 29 drives gear 1 to rotate in transmission groove 30. Gear 1 drives threaded rod 26 to rotate in sliding groove 25. Under the action of the thread, threaded rod 26 drives slide plate 22 to slide downward in sliding groove 25. Slide plate 22 also drives motor 1 23 and grinding brush 24 to move downward until several diamond brushes on the bottom of grinding brush 24 are completely in contact with the surface of ceramic valve ball. Then, the worker stops rotating handle 27. This process ensures that the large ceramic valve ball can be ground by the whole device.

[0077] Simultaneously, the second motor 31 is connected to the power supply and started. The output shaft of the second motor 31 drives the second transmission wheel 33 to rotate slowly. The second transmission wheel 33 drives the first transmission wheel 32 to rotate via the belt 34. The first transmission wheel 32 drives the limiting disc 4 to rotate slowly on the support plate 2 via the rotating roller 3. At the same time, the limiting disc 4 drives the telescopic rod 5 to rotate. Under the action of compression, the limiting disc 4 drives several support plates 9 to rotate through the cooperation of the limiting block 10 and the limiting groove 11. The several support plates 9 drive the telescopic rod 6 to rotate together through the corresponding connecting block 8. At the same time, the telescopic rod 6... The connecting roller 15 is driven by the latch 7 to rotate slowly on the output shaft of the hydraulic cylinder 16, while several support plates 9 are pressed against the inner wall of the ceramic valve ball by rubber pads. Under the action of friction, the support plates 9 drive the ceramic valve ball to rotate slowly, so that the entire large ceramic valve ball rotates in several diamond brushes at the bottom of the grinding brush plate 24, thereby making the surface of the ceramic valve ball grind by the grinding brush plate 24. This process ensures that the entire device can grind all surfaces of the ceramic valve ball without removing the ceramic valve ball, saving workers' working time. Example

[0080] This embodiment provides a fixing device for processing ceramic valve balls. In addition to the technical solution of the above embodiment, it also has the following technical features: the number of support plates 9 is at least 4, and the support plates 9 are distributed in a ring with equal spacing.

[0081] In particular, to ensure the structural stability of the overall device, several support plates 9 are evenly distributed on the inner wall of the large ceramic valve ball, thereby ensuring that the overall device can stably drive the ceramic valve ball to rotate. Example

[0082] This embodiment provides a fixing device for processing ceramic valve balls. In addition to the technical solutions of the above embodiments, it also has the following technical features: a suction pipe 20 is fixedly installed at the water inlet end of the water pump 18, and the bottom end of the suction pipe 20 passes through the top of the water tank 17 and extends into the water tank 17. Several nozzles are threadedly connected to the flexible metal pipe 19, and several nozzles are located between one of the support plates 9 and the second support plate 21.

[0083] Specifically, when the water pump 18 is powered on and started, it is ensured that the water pump 18 can draw out the grinding liquid from the water tank 17 through the suction pipe 20 and spray it onto the surface of the ceramic valve ball through several nozzles on the flexible metal pipe 19, ensuring that the nozzles do not spray the grinding liquid onto places other than the surface of the ceramic valve ball.

[0084] It is worth noting that the flexible metal tube 19 is made of flexible metal, which has flexibility and plasticity, allowing workers to bend and shape the flexible metal tube 19 at will, so that the several nozzles on the flexible metal tube 19 can spray the grinding fluid evenly onto the surface of the ceramic valve ball. Example

[0085] This embodiment provides a fixing device for processing ceramic valve balls. In addition to the technical solution of the above embodiment, it also has the following technical features: the motor 23 is fixed to the top of the slide plate 22 by several bolts, and the output shaft of the motor 23 passes through the slide plate 22 and is coaxially connected to the grinding brush plate 24. The output shaft of the motor 23 is rotatably connected to the slide plate 22.

[0086] Among them, it is ensured that motor 23 can drive the grinding brush 24 to rotate normally on the slide plate 22.

[0087] It is worth noting that the grinding brush 24 involved in this utility model is existing technology, and the several diamond brushes at the bottom of the grinding brush 24 can completely cover the surface of the large ceramic valve ball. This can be fully achieved by those skilled in the art, so there is no need to elaborate. The content protected by this utility model does not involve any improvement to the structure and working principle of the grinding brush 24.

[0088] Working principle: When grinding the surface of a large ceramic valve ball after drilling, the worker first places the drilled large ceramic valve ball onto several support plates 9. Then, the hydraulic cylinder 16 is powered on and started. The output shaft of the hydraulic cylinder 16 drives the connecting roller 15 to move towards the support plate 2, so that the groove 14 on the connecting roller 15 gradually approaches the bolt 7 and is inserted into the bolt 7. Subsequently, the output shaft of the hydraulic cylinder 16 continues to press the telescopic rod 6 through the connecting roller 15, so that the telescopic rod 6 slides towards the limiting plate 4 on the telescopic rod 5. At the same time, the spring 13 in the telescopic groove 12 begins to contract and generate elastic force under the pressure of the telescopic rod 5. Under the action of compression, the telescopic rod 26 drives several connecting blocks 8 to rotate, and through the connecting blocks 8, it compresses the corresponding support plate 9 away from the telescopic rod 26. At the same time, the support plates 9 drive the corresponding limiting blocks 10 to slide in the corresponding limiting grooves 11 and move away from the telescopic rod 15, so that the support plates 9 compress the inner wall of the drilled ceramic valve ball until the rubber pads on the support plates 9 compress the inner wall of the drilled ceramic valve ball and deform. At this time, the hydraulic cylinder 16 is closed. At this time, the large ceramic valve ball can be fixed in the overall device. This process ensures that the large ceramic valve ball can be fixed in the overall device. Then, the worker can carry out the next operation on the large ceramic valve ball.

[0089] Then, grinding fluid is injected into the water tank 17. The worker then adjusts the flexible metal tube 19 according to the diameter of the large ceramic valve ball, so that the flexible metal tube 19 is positioned between the ceramic valve ball and the support plate 21. At the same time, the nozzles on the flexible metal tube 19 are aligned with the surface of the ceramic valve ball. The worker then manually turns the handle 27, which drives the gear 29 to rotate. Under the action of meshing, the gear 29 drives the gear 1 to rotate, and the gear 1 to rotate the threaded rod 26. Under the action of the thread, the threaded rod 26 drives the slide plate 22 to slide downward in the slide groove 25. The slide plate 22 drives the motor 23 and the grinding brush plate 24 to move downward. When the diamond brushes on the bottom of the grinding brush plate 24 are completely in contact with the surface of the ceramic valve ball, the worker stops turning the handle 27.

[0090] Then, the second motor 31 is connected to the power supply and started. The output shaft of the second motor 31 drives the second transmission wheel 33 to rotate slowly. The second transmission wheel 33 drives the first transmission wheel 32 to rotate slowly through the belt 34. The first transmission wheel 32 drives the limiting plate 4 and the first telescopic rod 5 to rotate through the rotating roller 3. The limiting plate 4 drives several support plates 9 to rotate through the cooperation of the limiting block 10 and the limiting groove 11. The several support plates 9 drive the second telescopic rod 6 to rotate through the corresponding connecting block 8. The second telescopic rod 6 drives the connecting roller 15 to rotate slowly on the output shaft of the hydraulic cylinder 16 through the bolt 7. This causes the entire ceramic valve ball to rotate at the bottom of the grinding brush plate 24, thereby causing the surface of the large ceramic valve ball to be ground by the grinding brush plate 24.

[0091] Simultaneously, the power supply to motor 23 and water pump 18 is turned on and started. Water pump 18 transfers the grinding fluid in water tank 17 to flexible metal pipe 19 through suction pipe 20, and then sprays it onto the surface of ceramic valve ball through several nozzles on flexible metal pipe 19. The output shaft of motor 23 drives the grinding brush 24 to rotate, so that the grinding brush 24 can polish the surface of ceramic valve ball. Since the output shaft of motor 31 rotates slowly, the ceramic valve ball also rotates slowly in the whole device. Therefore, the grinding fluid used on the ceramic valve ball during the polishing process will fall directly into the sludge collection tank 35, preventing the grinding fluid from falling outside the whole device. The above-mentioned whole operation process avoids the need for workers to manually apply grinding fluid to the ceramic valve ball, ensuring the personal safety of workers. In addition, the device can evenly spray the grinding fluid on the surface of large ceramic valve ball, ensuring that the grinding fluid can be sprayed evenly. Furthermore, it also ensures that the whole device can polish all surfaces of large ceramic valve balls in one go, saving time and effort.
