Description

Technical Field

[0001] The present invention relates to the technical field of ball valve processing, and particularly relates to a deburring device for the end face of a ball valve. Background Art

[0002] A ball valve is a commonly used fluid control valve that realizes the opening, closing, or regulation of fluid by rotating the sphere (valve core) 90°. Due to its fast switching, reliable sealing, and wide applicability, the ball valve has become an indispensable component in industrial processes. Deburring the end face of the ball valve is an important step to ensure the valve's sealing performance and service life. Burrs may appear on the sealing surface (such as the contact surface between the valve seat and the sphere), connecting flange, or machining edge. If not properly treated, it will cause leakage, wear, or sealing failure.

[0003] The existing deburring methods mostly use hand-held tools to polish the end face of the ball valve, which is time-consuming and laborious, and the deburring efficiency is relatively low. When using mechanical equipment to automatically deburr the end face of the ball valve, it often only polishes the end face of the ball valve once. If there is oil stain, oxide scale, or impurities on the end face of the ball valve, it will result in incomplete deburring, scratching the surface, and low deburring quality, leading to poor precision of the end face of the ball valve. Summary of the Invention

[0004] Technical problems to be solved:

[0005] In view of the deficiencies of the prior art, the present invention provides a deburring device for the end face of a ball valve. The deburring process for the end face of the valve body includes surface cleaning, rough grinding, fine grinding, and polishing, which are carried out step by step. After removing the oil stain on the end face of the valve body, rough grinding is carried out first, then fine grinding, and finally polishing, which can optimize the surface quality, improve the precision of the end face of the ball valve. The fixing mechanism fixes the valve body and automatically reverses the valve body at the same time, improving the deburring processing efficiency and solving the technical problems mentioned in the background art.

[0006] Technical solutions:

[0007] To achieve the above object, the present invention is realized through the following technical solutions:

[0008] A ball valve end face deburring device includes a deburring mechanism and a fixing mechanism. The fixing mechanism is used to fix the valve body. The deburring mechanism includes a frame, on which a toothed disc is rotatably arranged. The toothed disc is driven by a first motor. At the lower end face of the toothed disc, there are a rough grinding component, a fine grinding component, a first spray pipe, a second spray pipe, a first wiping component and a second wiping component. At the upper end face of the toothed disc, there are a cleaning liquid storage tank and a polishing liquid storage tank. Quantitative pumps are installed at the bottoms of the cleaning liquid storage tank and the polishing liquid storage tank. The rough grinding component includes a first mounting frame, on which a second motor is installed.

The deburring process of the valve body end face includes surface cleaning, rough grinding, fine grinding and polishing, which are carried out step by step. After removing the oil stain on the valve body end face, rough grinding is carried out first, then fine grinding, and finally polishing.

[0009] In a possible implementation manner, the quantitative pump at the bottom of the cleaning liquid storage tank is connected to the first spray pipe through a delivery pipe. The cleaning liquid enters the first spray pipe through the delivery pipe and is sprayed onto the valve body end face through the first spray pipe.

[0010] In a possible implementation manner, the quantitative pump at the bottom of the polishing liquid storage tank is connected to the second spray pipe through a delivery pipe. The polishing liquid enters the second spray pipe through the delivery pipe and is sprayed onto the valve body end face through the first spray pipe.

[0011] In a possible implementation manner, multiple groups of nozzles are arranged on both the first spray pipe and the second spray pipe, and the multiple groups of nozzles are evenly distributed at intervals along the axial direction of the first spray pipe and the second spray pipe.

[0012] In a possible implementation manner, screw holes are formed in the wiping roller, and a connecting shaft is fixedly arranged at the lower end face of the toothed disc. The connecting shaft includes a stud, and the stud of the connecting shaft is threadedly connected to the screw holes of the wiping roller, which is convenient for replacing the wiping roller.

[0013] In a possible implementation manner, the output shaft of the first motor is fixedly connected to a gear through a coupling, and the gear meshes with the toothed disc. When the first motor works, it drives the gear at one end to rotate. Through the meshing transmission between teeth, it drives the toothed disc to rotate relative to the frame.

[0014] In a possible implementation, the fixing mechanism includes a U-shaped frame, an adjusting plate, and a bottom plate. A first electric cylinder is installed on the bottom plate. One end of the push rod of the first electric cylinder is fixedly connected to a first sliding seat. A second electric cylinder is installed on the adjusting plate. One end of the push rod of the second electric cylinder is fixedly connected to a second sliding seat. The positions of the valve body in the X-axis direction and the Y-axis direction are adjusted by the first electric cylinder and the second electric cylinder.

[0015] In a possible implementation, a fifth motor is installed on one side surface of the U-shaped frame. The output shaft of the fifth motor is fixedly connected to a bidirectional lead screw through a coupling. A slide bar is arranged on one side of the bidirectional lead screw. Both the bidirectional lead screw and the slide bar pass through two groups of locking plates, and the locking plates are slidably connected to the slide bar. The two groups of locking plates are respectively sleeved on both sides of the bidirectional lead screw. The valve body is clamped and fixed by the U-shaped frame.

[0016] In a possible implementation, a fourth motor is installed on the second sliding seat. The output shaft of the fourth motor is fixedly connected to the U-shaped frame. When the fourth motor works, it drives the U-shaped frame to rotate, and after the deburring process is completed, the valve body is automatically reversed.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, the first motor drives the gear disk to rotate relative to the frame, adjusts the positions of the components below it, drives a certain component to the working position, and performs corresponding processing on the end face of the valve body. Before deburring, the cleaning liquid is sprayed on the end face of the valve body through the first spray pipe. After cleaning, it is wiped dry by the first wiping component. The end face of the valve body is coarsely ground and deburred by the coarse grinding component, and finely ground and deburred by the fine grinding component. After deburring, the polishing liquid is sprayed on the end face of the valve body through the second spray pipe. After polishing, it is wiped dry by the second wiping component. The deburring process of the end face of the valve body includes surface cleaning, coarse grinding, fine grinding, and polishing, which are carried out step by step. After removing the oil stain on the end face of the valve body, it is first coarsely ground and then finely ground, and finally polished, which can optimize the surface quality and improve the precision of the ball valve end face.

Detailed implementation mode

[0033] In the embodiment of the present application, a deburring device for the end face of a ball valve is provided. The deburring process for the end face of the valve body includes surface cleaning, rough grinding, fine grinding, and polishing. These steps are carried out step by step. After removing the oil stain on the end face of the valve body, rough grinding is carried out first, then fine grinding, and finally polishing. This can optimize the surface quality and improve the precision of the end face of the ball valve. While fixing the valve body, the fixing mechanism automatically reverses the valve body, improving the deburring processing efficiency and solving the technical problems mentioned in the background art.

[0034] The technical solution in the embodiment of the present application is to solve the problems in the above background art, and the general idea is as follows:

[0035] Embodiment 1:

[0036] Please refer to Figures 1 - 10, the present invention provides a technical solution: a deburring device for the end face of a ball valve, including a deburring mechanism 1 and a fixing mechanism 2. The fixing mechanism 2 is used to fix the valve body 3. The deburring mechanism 1 includes a frame 11, on which a toothed disc 12 is rotatably arranged. The toothed disc 12 is driven by a first motor 13. At the lower end face of the toothed disc 12, there are a rough grinding assembly 15, a fine grinding assembly 16, a first spray pipe 17, a second spray pipe 18, a first wiping assembly 19 and a second wiping assembly 110. At the upper end face of the toothed disc 12, there are a cleaning liquid storage tank 111 and a polishing liquid storage tank 112. Quantitative pumps 113 are installed at the bottoms of the cleaning liquid storage tank 111 and the polishing liquid storage tank 112. The rough grinding assembly 15 includes a first mounting frame 151, on which a second motor 152 is installed. The output shaft of the second motor 152 is fixedly connected to a rough grinding roller 153 through a coupling. The fine grinding assembly 16 includes a second mounting frame 161, on which a third motor 162 is installed. The output shaft of the third motor 162 is fixedly connected to a fine grinding roller 163 through a coupling. Both the first wiping assembly 19 and the second wiping assembly 110 include a wiping roller 191, and a wiping layer 192 is arranged outside the wiping roller 191.

[0037] When the first motor 13 works, it drives the toothed disc 12 to rotate relative to the frame 11. During the rotation of the toothed disc 12, the positions of the components below it are adjusted, and a certain component is driven to the working position to perform corresponding processing on the end face of the valve body 3.

[0038] Before deburring, cleaning liquid such as anhydrous ethanol or acetone is sprayed onto the end face of the valve body 3 through the first spray pipe 17. The corresponding cleaning liquid is selected according to the material type of the valve body 3. The end face of the valve body 3 is wiped through the first wiping assembly 19, the end face of the valve body 3 is roughly ground to remove burrs through the rough grinding assembly 15, and the end face of the valve body 3 is finely ground to remove burrs through the fine grinding assembly 16. After deburring, polishing liquid is sprayed onto the end face of the valve body 3 through the second spray pipe 18. For stainless steel materials, a mixed solution containing nitric acid and hydrofluoric acid is used; for aluminum materials, a neutral or weakly alkaline solution is used; for copper materials, ferric chloride solution or sulfur-containing compounds are used. The corresponding polishing liquid is selected according to the material type of the valve body 3. By spraying the polishing liquid onto the end face of the valve body 3, the surface is refined, the processing marks of deburring are eliminated, and the surface finish of the end face of the valve body 3 is improved. Finally, the end face of the valve body 3 is wiped through the second wiping assembly 110.

[0039] The deburring process for the end face of the valve body 3 includes surface cleaning, rough grinding, fine grinding and polishing, which are carried out step by step. After removing the oil stain on the end face of the valve body 3, rough grinding is carried out first and then fine grinding, which can optimize the surface quality. The scratches generated during rough grinding are eliminated during fine grinding. After rough grinding, there are macroscopic unevenness on the end face. Fine grinding fills these defects with smaller abrasives. In the rough grinding stage, large-particle abrasives undertake the main grinding task to avoid premature wear of fine-particle abrasives. The fine grinding assembly 16 focuses on fine grinding and trimming, and extends the service life of the fine grinding assembly 16.

[0040] Before deburring, the cleaning liquid is sprayed onto the end face of the valve body 3 through the first spray pipe 17. After cleaning, it is wiped dry by the first wiping assembly 19 to remove impurities such as oil stains and dust on the end face of the valve body 3, ensuring the cleanliness of the end face of the valve body 3, and thus improving the deburring quality.

[0041] When the second motor 152 works, it drives the rough grinding roller 153 at one end to rotate. When the rotating rough grinding roller 153 contacts the end face of the valve body 3, rough grinding of the end face of the valve body 3 is achieved. When the third motor 162 works, it drives the fine grinding roller 163 at one end to rotate. When the rotating fine grinding roller 163 contacts the end face of the valve body 3, fine grinding of the end face of the valve body 3 is achieved. The fixing mechanism 2 is used to fix the valve body 3, and at the same time, it can adjust the position of the valve body 3 in the X-axis direction and the Y-axis direction. The fixing mechanism 2 fixes the valve body 3 and drives the valve body 3 to move, driving the valve body 3 to the deburring processing area to achieve deburring processing.

[0042] In some examples, a metering pump 113 at the bottom of the cleaning liquid storage tank 111 is connected to the first spray pipe 17 through a delivery pipe 114.

[0043] When the metering pump 113 at the bottom of the cleaning liquid storage tank 111 works, it extracts the cleaning liquid inside the cleaning liquid storage tank 111. The cleaning liquid enters the first spray pipe 17 through the delivery pipe 114, is sprayed out through the first spray pipe 17, and is sprayed onto the end face of the valve body 3 to clean the end face of the valve body 3 and remove impurities such as oil stains and dust on the end face of the valve body 3.

[0044] In some examples, a metering pump 113 at the bottom of the polishing liquid storage tank 112 is connected to the second spray pipe 18 through a delivery pipe 114.

[0045] When the metering pump 113 at the bottom of the polishing liquid storage tank 112 works, it extracts the polishing liquid inside the polishing liquid storage tank 112. The polishing liquid enters the second spray pipe 18 through the delivery pipe 114, is sprayed out through the second spray pipe 18, and is sprayed onto the end face of the valve body 3 to perform final polishing on the end face of the valve body 3, improving the precision of the end face of the ball valve.

[0046] In some examples, multiple groups of nozzles 171 are provided on both the first spray pipe 17 and the second spray pipe 18. The multiple groups of nozzles 171 are evenly distributed at intervals along the axial direction of the first spray pipe 17 and the second spray pipe 18. The cleaning liquid entering the first spray pipe 17 is finally evenly sprayed out through the multiple groups of nozzles 171 of the first spray pipe 17, and the polishing liquid entering the second spray pipe 18 is finally evenly sprayed out through the multiple groups of nozzles 171 of the second spray pipe 18.

[0047] In some examples, screw holes are provided on the wiping roller 191, and a connecting shaft 193 is fixedly arranged on the lower end surface of the tooth disc 12. The connecting shaft 193 includes a stud, and the stud of the connecting shaft 193 is threadedly connected to the screw hole of the wiping roller 191, as Figure 8 shown, the connecting shaft 193 is fixedly connected to the wiping roller 191 by threads, the two are detachable, and the connection method is simple, which is convenient for replacing the wiping layers 192 of the first wiping assembly 19 and the second wiping assembly 110.

[0048] In some examples, the output shaft of the first motor 13 is fixedly connected to the gear 14 through a coupling, and the gear 14 meshes with the tooth disc 12.

[0049] When the first motor 13 works, it drives the gear 14 at one end to rotate. Through the meshing transmission between teeth, it drives the tooth disc 12 to rotate relative to the frame 11. During the rotation of the tooth disc 12, it drives the rough grinding assembly 15, the fine grinding assembly 16, the first spray pipe 17, the second spray pipe 18, the first wiping assembly 19, the second wiping assembly 110 below it, and the cleaning liquid storage tank 111 and the polishing liquid storage tank 112 above it to move synchronously, so as to adjust the positions of each component.

[0050] As Figure 3 shown, the position close to the end face of the valve body 3 is the processing position. When the first spray pipe 17 is driven by the first motor 13 to the processing position, the cleaning liquid is sprayed through the first spray pipe 17 to clean the end face of the valve body 3. When the first wiping assembly 19 is driven by the first motor 13 to the processing position, the end face of the valve body 3 is wiped through the first wiping assembly 19. When the rough grinding assembly 15 is driven by the first motor 13 to the processing position, the end face of the valve body 3 is roughly ground through the rough grinding assembly 15. When the fine grinding assembly 16 is driven by the first motor 13 to the processing position, the end face of the valve body 3 is finely ground through the fine grinding assembly 16. When the second spray pipe 18 is driven by the first motor 13 to the processing position, the polishing liquid is sprayed through the second spray pipe 18 to polish the end face of the valve body 3. When the second wiping assembly 110 is driven by the first motor 13 to the processing position, the end face of the valve body 3 is wiped through the second wiping assembly 110, so as to realize multi-step continuous processing, replace manual deburring, and save time and effort, improve the deburring efficiency, and the positions of each component are controlled by the rotation direction and the number of rotation circles of the output shaft of the first motor 13.

[0051] By adopting the above technical solutions:

[0052] The toothed disc 12 is driven by the first motor 13 to rotate relative to the frame 11, and the position of each component below it is adjusted. A certain component is driven to the working position to perform corresponding machining on the end face of the valve body 3. Before deburring, the cleaning liquid is sprayed on the end face of the valve body 3 through the first spray pipe 17, and after cleaning, it is wiped dry by the first wiping component 19. The end face of the valve body 3 is rough-ground to remove burrs by the rough grinding component 15, and fine-ground to remove burrs by the fine grinding component 16. After deburring, the polishing liquid is sprayed on the end face of the valve body 3 through the second spray pipe 18, and after polishing, it is wiped dry by the second wiping component 110. The deburring process of the end face of the valve body 3 includes surface cleaning, rough grinding, fine grinding, and polishing, which are carried out step by step. After removing the oil stain on the end face of the valve body 3, it is first rough-ground and then fine-ground, and finally polished, which can optimize the surface quality and improve the precision of the ball valve end face.

[0053] Embodiment 2:

[0054] Based on Embodiment 1, this embodiment introduces the specific structure of the fixing mechanism 2 in a ball valve end face deburring device. The fixing mechanism 2 includes a U-shaped frame 21, an adjusting plate 22, and a bottom plate 23. A first electric cylinder 24 is installed on the bottom plate 23, and one end of the push rod of the first electric cylinder 24 is fixedly connected to a first sliding seat 25. A second electric cylinder 26 is installed on the adjusting plate 22, and one end of the push rod of the second electric cylinder 26 is fixedly connected to a second sliding seat 27.

[0055] The valve body 3 is installed and fixed on the U-shaped frame 21. When the first electric cylinder 24 works, it drives the first sliding seat 25 at one end, and the first sliding seat 25 drives the upper U-shaped frame 21 to move synchronously. When the second electric cylinder 26 works, it drives the second sliding seat 27 at one end, and the second sliding seat 27 drives the upper U-shaped frame 21 to move synchronously. The valve body 3 moves synchronously with the U-shaped frame 21. By controlling the telescopic stroke of the first electric cylinder 24 and the second electric cylinder 26, the position of the valve body 3 can be flexibly adjusted.

[0056] When the rotating rough grinding roller 153 contacts the end face of the valve body 3, the valve body 3 is driven to move linearly by the first electric cylinder 24, so that there is no dead angle contact between the end face of the valve body 3 and the rough grinding roller 153, realizing rough grinding and deburring of the end face. When the rotating fine grinding roller 163 contacts the end face of the valve body 3, the valve body 3 is driven to move linearly by the first electric cylinder 24, so that there is no dead angle contact between the end face of the valve body 3 and the fine grinding roller 163, realizing fine grinding and deburring of the end face. Similarly, when the wiping roller 191 contacts the end face of the valve body 3, the valve body 3 is driven to move linearly by the first electric cylinder 24, so that there is no dead angle contact between the end face of the valve body 3 and the wiping roller 191, realizing wiping dry.

[0057] In some examples, a fifth motor 211 is installed on one side surface of the U-shaped frame 21. The output shaft of the fifth motor 211 is fixedly connected to a bidirectional lead screw 212 through a coupling. A slide bar 213 is arranged on one side of the bidirectional lead screw 212. Both the bidirectional lead screw 212 and the slide bar 213 pass through two sets of locking plates 214, and the locking plates 214 are slidably connected to the slide bar 213. The two sets of locking plates 214 are respectively sleeved on both sides of the bidirectional lead screw 212.

[0058] When the fifth motor 211 works, it drives the bidirectional lead screw 212 at one end to rotate, and then drives the two sets of locking plates 214 to slide along the slide bar 213, driving the two sets of locking plates 214 to approach each other or move away from each other. When the two sets of locking plates 214 approach each other, the valve body 3 is clamped and fixed. When the two sets of locking plates 214 move away from each other, the valve body 3 is released, facilitating the clamping of the valve body 3.

[0059] In some examples, a fourth motor 28 is installed on the second slide base 27. The output shaft of the fourth motor 28 is fixedly connected to the U-shaped frame 21.

[0060] When the fourth motor 28 works, it drives the U-shaped frame 21 to make a rotational movement. After deburring the end face on one side of the valve body 3 is completed, the fourth motor 28 drives the valve body 3 to make a rotational movement, driving the other end face of the valve body 3 to the processing position for deburring, without the need for manual manual commutation of the valve body 3.

[0061] In some examples, a first slide rail 231 is arranged on the bottom plate 23. The first slide rail 231 is slidably connected to the first slide base 25. A second slide rail 221 is arranged on the adjusting plate 22. The second slide rail 221 is slidably connected to the second slide base 27. The first slide base 25 is fixedly connected to the adjusting plate 22. The first slide base 25 slides along the first slide rail 231 driven by the first electric cylinder 24, and the second slide base 27 slides along the second slide rail 221 driven by the second electric cylinder 26.

[0062] By adopting the above technical solutions:

[0063] While the fixing mechanism 2 fixes the valve body 3, it can adjust the position of the valve body 3 in the X-axis direction and the Y-axis direction. By adjusting the position of the end face of the valve body 3, comprehensive deburring can be achieved, and after the deburring process is completed, the valve body 3 can be automatically commutated, replacing manual manual commutation, saving time and effort, and improving the deburring processing efficiency.

[0064] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
