Description

Technical Field

[0001] The present invention belongs to the technical field of turning and grinding, and specifically relates to a special machine for turning and grinding butterfly valve valve bodies. Background Art

[0002] A butterfly valve, also known as a flap valve, is a simple-structured regulating valve. A butterfly valve used for switching control of media in low-pressure pipelines refers to a valve flap or butterfly plate that rotates around a valve shaft to achieve opening and closing. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. It mainly functions as a cut-off and throttling device in pipelines. The closing and opening member of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis inside the valve body to achieve the purpose of closing, opening, or adjusting.

[0003] There is a grinding device and grinding method for a butterfly valve valve body with a publication number of CN117961689A. The upper and lower surfaces of the butterfly valve valve body are synchronously polished by the top grinding disc of the first motor and the bottom grinding disc of the second motor, achieving high-efficiency grinding of the butterfly valve valve body. However, for actual butterfly valve components, the outer surface is not a flat surface. Direct use of the grinding disc cannot effectively polish the convex or concave parts of the butterfly valve, resulting in a large number of burrs still remaining on the outer surface of the final finished butterfly valve. Therefore, improvement work is needed. Summary of the Invention

[0004] Aiming at the problem that the prior art is prone to overlooking burrs on the outer surface of the butterfly valve during the grinding operation, the technical solution adopted by the present invention is as follows: A special machine for turning and grinding butterfly valve valve bodies, comprising: A cover assembly for placing the butterfly valve to be polished, and the interior of the cover assembly is filled with polishing balls; An inner grinding assembly for grinding the inner wall of the butterfly valve; A material receiving cylinder arranged directly below the cover assembly for receiving the waste materials after grinding; The cover assembly includes: Docking shells, the number of the docking shells is two, and an axial limiting ring is provided at the axis of the inner wall of the docking shell. After the butterfly valve is placed inside the docking shell, the circular groove at its central part is sleeved on the axial limiting ring, playing a role in restricting the movement of the butterfly valve; A material conveying through pipe arranged inside the docking shell through a through port, and a plug is arranged inside the material conveying through pipe. After filling the inside of the docking shell with small grinding balls through the material conveying through pipe, the material conveying through pipe is blocked with the plug; An extended bottom shell arranged at the axis of the outer surface of the docking shell; The inner grinding assembly includes: A contact assembly for directly contacting and rubbing against the arc-shaped inner wall of the butterfly valve; The control component directly drives the contact component to perform rotational and sliding movements.

[0005] Furthermore, it also includes The flipping component is directly connected to the lid-closing component and is used to control the lid-closing component and the internal butterfly valve to rotate; The flipping component has: Side frames, the number of the side frames is two groups, which are arranged on the ground, and torque motors are symmetrically arranged on both sides of the outer surface of the side frames; The transmission torsion wheel, the axis at the inner wall of the transmission torsion wheel is inserted into the output shaft of the torque motor; The transmission belt, both sides of the inner wall of the transmission belt are in rolling connection with the outer surface of the transmission torsion wheel, and the inside of the transmission belt is propped open and shaped by a plate body; The axis rotating wheel, the outer surface of the axis rotating wheel is in rolling connection with the middle part of the inner wall of the transmission belt, the axis rotating wheel is arranged at the central position through the skeleton plate inside the transmission belt, and rotates automatically under the friction of the transmission belt; The plugging component is used to connect the axis rotating wheel and the lid-closing component.

[0006] Furthermore, the plugging component includes The filling shaft rod, vertical plug plates are symmetrically arranged on the upper and lower sides of the outer surface of the filling shaft rod, and elastic joints are evenly arranged in the inner cavity of the vertical plug plates. The elastic joints are as Figure 5 shown. When the compression cylinder in the middle can be extended under the control of an external remote control, the elastic joints at both ends are inserted into the docking slots of the docking shell, so as to ensure the connection function of the vertical plug plates. The outer surface of the vertical plug plates is inserted into the inner cavity of the docking shell through the docking slots, and the outer surface of the elastic joints is inserted into the inner cavity of the docking shell through the docking slots. The upper and lower docking shells are connected and merged into a complete sealed shell through the filling shaft rod to cover the internal butterfly valve; The fixed end head, the outer surface of the fixed end head is fixedly connected to the inner cavity of the filling shaft rod through the receiving groove.

[0007] Furthermore, the flipping component also includes The connecting rotating rod, one end of the connecting rotating rod is fixedly connected to the axis at the inner wall of the axis rotating wheel, and the other end of the connecting rotating rod is rotatably connected to the inner cavity of the filling shaft rod through the receiving groove; The elastic sleeve, the inner wall of the elastic sleeve is sleeved on the side of the outer surface of the connecting rotating rod away from the axis rotating wheel; The docking pressure rod is evenly arranged at the end of the connecting rod away from the axial rotating wheel, and the outer surface of the docking pressure rod and the outer surface of the fixed end are pressed against each other. When the docking pressure rod is staggered with the fixed end, under the elastic force of the elastic ring, the connecting rod will be slightly inserted into the depth of the accommodating groove, thereby achieving the effect of side pushing the filling shaft rod and the docking shell.

[0008] Furthermore, the control component includes: A shaft rotating drum, wherein the inner cavity of the shaft rotating drum is evenly provided with vertical grooves, and the outer surface of the shaft rotating drum is plugged into the inner wall of the shaft limiting ring; A built-in turntable, wherein the outer surface of the output shaft of the built-in turntable is plugged into the axis of the outer surface of the axis rotating cylinder, and the outer surface of the built-in turntable is fixedly connected to the axis of the inner wall of the extended bottom shell; Sliding connecting tube, wherein the upper and lower ends of the sliding connecting tube are symmetrically provided with elastic sleeves, and the air pressure entering from the upper and lower ends of the sliding connecting tube will be discharged outward through the side openings of the sliding connecting tube, and after the shaft rod of the built-in rotating disk is inserted into the docking port at the axis center outside the sliding connecting tube, the built-in rotating disk can directly drive the sliding connecting tube to rotate; The blower has its outer surface fixedly connected to the end of the elastic sleeve away from the sliding tube at the axis center, and its outer surface is fixedly connected to the inner wall of the axis rotating cylinder. When there is a difference in wind force between the upper and lower blowers, the sliding tube will be blown by the blower on the side with greater wind force, and then slide to a position close to the blower on the other side.

[0009] Furthermore, the contact component includes: A built-in plate shell, the outer surface of which is fixedly connected to the inner cavity of the axial rotating cylinder through a vertical groove, and a rubber sealing belt is symmetrically arranged on one side of the inner wall of the built-in plate shell away from the sliding connecting tube, and the rubber sealing belt can prevent the put-in grinding ball particles from entering the interior of the built-in plate shell; The grinding inner plate, the outer surface of the grinding inner plate is evenly provided with grinding balls on one side away from the sliding tube, the inner cavity of the grinding inner plate is fixedly connected to the interface of the outer surface of the sliding tube through the connecting pipe, the outer surface of the grinding inner plate is slidably connected to the inner wall of the built-in plate shell, and the outer surface of the rubber sealing belt is slidably connected to the outer surface of the grinding inner plate, the grinding inner plate is a hollow plate body, and the air pressure entering the grinding inner plate from the connecting pipe will be ejected outward from the nozzle of the grinding inner plate, such as Figure 8 As shown, its nozzle position is located in the area between adjacent grinding balls.

[0010] Furthermore, the contact component further includes: Side rotating wheel, the outer surface of the side rotating wheel is meshed and connected with the outer surface of the grinding inner plate through a turning groove. On both the upper and lower sides of the side rotating wheel, control motors are symmetrically arranged through shaft rods, and the outer surface of the control motor is fixedly connected with the outer surface of the built-in plate housing through a fixing plate. When the grinding inner plate slides relative to the built-in plate housing under the control of the side rotating wheel, the rubber sealing belt also slides relative to the outer surface of the grinding inner plate, always preventing grinding ball particles from entering the interior of the built-in plate housing.

[0011] The beneficial effects of the present invention are as follows: 1. The device can polish the outer surface of the butterfly valve limited by the shaft center limiting ring through the fine grinding balls filled inside the cover closing component. Since the grinding balls are small and continuously change their positions with the flipping movement of the cover closing component, it is ensured that the grinding balls can effectively contact the outer surface of the butterfly valve. For a butterfly valve with many concave and convex surfaces on its outer shape, effective polishing work can be carried out on the dead corner parts, thereby removing the burrs on the outer surface of the protruding or sunken parts of the butterfly valve and avoiding the problem of a large amount of burrs remaining on the outer surface of the butterfly valve.

[0012] 2. In order to avoid the problem that the grinding balls inside the cover closing component gather on one side due to centrifugal rotation, resulting in a decrease in the possibility of contact between the grinding balls and the butterfly valve, during the process of the flipping component controlling the flipping of the cover closing component, by using the principle that the connecting rotating rod and the filling shaft rod slip, the cover closing component moves continuously in the left and right directions, thereby dispersing the grinding balls gathered by centrifugal force, making the movement of the grinding balls irregular, and the probability of contact with the outer surface of the butterfly valve will also increase significantly. Not only can effective polishing work be achieved, but also the efficiency of sphere polishing will be improved.

[0013] 3. The inner wall part of the butterfly valve does not contact the grinding balls inside the docking shell, so an inner grinding component is needed to polish the inner wall of the butterfly valve. In order to ensure that the grinding balls can contact the inner walls of butterfly valves of different models, the grinding inner plate is designed to be a pushable structure. When the grinding balls rotate relative to the butterfly valve, the inner wall of the butterfly valve can be polished through friction. And when the grinding inner plate rotates, it also slides up and down relative to the built-in plate housing, thereby achieving the effect of comprehensively polishing the inner wall of the butterfly valve with fewer grinding balls. With fewer grinding balls, the volume of the grinding balls can be designed to be larger, thereby improving the actual service life and wear resistance of the grinding balls and ensuring that the grinding inner plate can carry out polishing work for a long time.

[0014] 4. When the axial rotating cylinder rotates on its own axis, the blowers on the upper and lower sides start to alternately blow air. The wind force of the blowers will enter the hollow inner grinding plate through the sliding connecting cylinder and the connecting pipe, and spray out towards the direction of the inner wall of the butterfly valve through the through holes of the inner grinding plate, so as to blow away the debris generated on the inner wall of the butterfly valve due to the grinding work, and avoid the problem that the debris ground by the grinding balls adheres to the outer surface of the axial rotating cylinder, resulting in the inability of the axial rotating cylinder to rotate smoothly.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0018] Example 1, please refer to Figures 1-5 , the present invention provides a technical solution: a special lathe and grinder for butterfly valve bodies, including: A cover assembly 1 for placing the butterfly valve to be polished, and the inside of the cover assembly 1 is filled with polishing balls; An internal grinding component 2 for grinding the inner wall of the butterfly valve; A material receiving cylinder 4 is arranged directly below the cover assembly 1 for receiving the waste after polishing; The cover assembly 1 includes: Two docking shells 11. An axial limiting ring 13 is provided at the axis of the inner wall of the docking shell 11. After the butterfly valve is placed inside the docking shell 11, the circular groove at its central part is sleeved on the axial limiting ring 13 to play a role in restricting the movement of the butterfly valve; A material conveying through pipe 12 is arranged in the inner cavity of the docking shell 11 through a through port, and a plug is arranged in the inner cavity of the material conveying through pipe 12. After filling the inside of the docking shell 11 with small grinding balls through the material conveying through pipe 12, the material conveying through pipe 12 is blocked with a plug; An extended bottom shell 14 is arranged at the axis of the outer surface of the docking shell 11; The internal grinding component 2 includes: A contact component 22 for directly contacting and rubbing against the arc-shaped inner wall of the butterfly valve; A control component 21 directly drives the contact component 22 to rotate and slide.

[0019] It also includes, A flipping component 3 is directly connected to the cover assembly 1 for controlling the rotation of the cover assembly 1 and the butterfly valve inside; The flipping component 3 has: Two side frames 31 are arranged on the ground. Torque motors are symmetrically arranged on both sides of the outer surface of the side frames 31; A transmission torsion wheel 32, and the axis of the inner wall of the transmission torsion wheel 32 is inserted into the output shaft of the torque motor; A transmission belt 33, both sides of the inner wall of the transmission belt 33 are in rolling connection with the outer surface of the transmission torsion wheel 32, and the inside of the transmission belt 33 is propped open and shaped by a plate body; Axial center rotating wheel 34, the outer surface of the axial center rotating wheel 34 is in rolling connection with the middle part of the inner wall of the transmission belt 33. The axial center rotating wheel 34 is arranged at the central position through the skeleton plate inside the transmission belt 33 and rotates self - driven under the frictional action of the transmission belt 33; Insertion component 5, used to connect the axial center rotating wheel 34 and the closing cover component 1.

[0020] The insertion component 5 includes, Filling shaft rod 51, on the upper and lower sides of the outer surface of the filling shaft rod 51, vertical insertion plates 52 are symmetrically arranged. Inside the cavity of the vertical insertion plates 52, elastic joints 53 are evenly arranged. As shown in Figure 5 the figure, when the compression cylinder in the middle can be extended under the control of an external remote control, the elastic joints 53 at both ends are inserted into the docking slots 15 of the docking shell 11, so as to ensure the connection function of the vertical insertion plates 52. The outer surface of the vertical insertion plates 52 is inserted into the inner cavity of the docking shell 11 through the docking slots 15, and the outer surface of the elastic joints 53 is inserted into the inner cavity of the docking shell 11 through the docking slots 15. The docking shells 11 on the upper and lower sides are connected and combined into a complete sealed shell through the filling shaft rod 51 to cover the internal butterfly valve; Fixed end head 55, the outer surface of the fixed end head 55 is fixedly connected to the inner cavity of the filling shaft rod 51 through the receiving groove 54.

[0021] The flipping component 3 further includes, Connecting rotating rod 35, one end of the connecting rotating rod 35 is fixedly connected to the axis at the inner wall of the axial center rotating wheel 34, and the other end of the connecting rotating rod 35 is rotatably connected to the inner cavity of the filling shaft rod 51 through the receiving groove 54; Elastic sleeve 37, the inner wall of the elastic sleeve 37 is sleeved on the side of the outer surface of the connecting rotating rod 35 far from the axial center rotating wheel 34; Docking pressure rod 36, the docking pressure rod 36 is evenly arranged at one end of the connecting rotating rod 35 far from the axial center rotating wheel 34, and the outer surface of the docking pressure rod 36 is mutually extruded with the outer surface of the fixed end head 55. When the docking pressure rod 36 and the fixed end head 55 are staggered, under the elastic action of the elastic sleeve 37, the connecting rotating rod 35 will slightly insert deeper into the receiving groove 54, so as to achieve the effect of laterally pushing the filling shaft rod 51 and the docking shell 11.

[0022] The control component 21 includes, Axial center rotating cylinder 211, vertical cutting grooves 212 are evenly opened in the inner cavity of the axial center rotating cylinder 211, and the outer surface of the axial center rotating cylinder 211 is inserted into the inner wall of the axial center limiting ring 13; Built - in turntable 213, the outer surface of the output shaft of the built - in turntable 213 is inserted into the axis at the outer surface of the axial center rotating cylinder 211, and the outer surface of the built - in turntable 213 is fixedly connected to the axis at the inner wall of the extended bottom shell 14; Sliding connecting cylinder 214, elastic connecting sleeves 215 are symmetrically arranged at the upper and lower ends of the sliding connecting cylinder 214. The air pressure entering from the upper and lower ends of the sliding connecting cylinder 214 will be discharged outward through the side ports of the sliding connecting cylinder 214. After the shaft rod of the built-in turntable 213 is inserted into the docking port at the center of the outside of the sliding connecting cylinder 214, the built-in turntable 213 can directly drive the sliding connecting cylinder 214 to rotate self - sufficiently; Blower 216, the center of the outer surface of the blower 216 is fixedly connected to one end of the elastic connecting sleeve 215 away from the sliding connecting cylinder 214, and the outer surface of the blower 216 is fixedly connected to the inner wall of the axial center rotating cylinder 211. When there is a difference in the wind force of the blowers 216 on the upper and lower sides, the sliding connecting cylinder 214 will be blown by the blower 216 on the side with the greater wind force, and then slide towards the position closer to the blower 216 on the other side.

[0023] After opening the cover - closing component 1, with the axial center limiting ring 13 as the center, insert it into the center position of the butterfly valve. Then connect the two flipping components 3 to the docking shell 11 through the plugging component 5, that is, place the filling shaft rod 51 at the docking notch 15, insert the vertical insertion plate 52 at the lower part of the filling shaft rod 51 into the inside of the docking notch 15, then place the upper docking shell 11, and also insert the upper vertical insertion plate 52 into the docking notch 15 of the upper docking shell 11. Then use the remote control to start the push cylinder in the middle of the fixed end 55, and the elastic joint 53 is inserted into the preset groove deep in the docking notch 15 to form a relatively airtight cover - closing component 1.

[0024] Block the material - conveying pipe 12 of the lower docking shell 11, and fill small grinding balls into the inside of the cover - closing component 1 through the material - conveying pipe 12 of the upper docking shell 11. After adding an appropriate amount of grinding balls, then block the material - conveying pipe 12 of the upper docking shell 11 to complete the preparatory work.

[0025] The side frame 31 drives the transmission torsion wheel 32 and the transmission belt 33 to rotate through the motor, so that the two axial center rotating wheels 34 can synchronously twist the connecting rod 35. Then, under the action of friction, drive the filling shaft rod 51 to rotate self - sufficiently. Since the filling shaft rod 51 is tightly connected to the cover - closing component 1 at this time, the docking shell 11 also rotates. Since the butterfly valve is limited by the axial center limiting ring 13 inside the docking shell 11, the butterfly valve will not collide with the inner wall of the docking shell 11. However, during the continuous turning of the grinding balls inside the docking shell 11, they will continuously contact the outer surface of the butterfly valve at high frequency, thus achieving the grinding effect.

[0026] When the rotational speed of the connecting rotating rod 35 is relatively high, the connecting rotating rod 35 will slip relative to the filling shaft rod 51, causing the docking pressure rod 36 to rotate out of position relative to the fixed end 55. As a result, the docking pressure rod 36 continuously pushes the cover component 1 through the fixed end 55. At this time, during the rotation of the cover component 1 around the axis, the cover component 1 also shakes continuously in the left-right direction, preventing the internal grinding balls from moving only under the action of centrifugal rotation. This makes the movement of the grinding balls irregular and avoids the problem of the grinding balls shifting unilaterally on the inner wall of the cover component 1 due to centrifugal force.

[0027] Example 2. Please refer to Figures 1-8 , the present invention provides a technical solution: on the basis of Example 1, the contact component 22 includes, an inner built-in plate shell 221. The outer surface of the inner built-in plate shell 221 is fixedly connected to the inner cavity of the axial center rotating cylinder 211 through a vertical cutting groove 212. On the side of the inner wall of the inner built-in plate shell 221 away from the sliding connecting cylinder 214, rubber sealing tapes 224 are symmetrically arranged. The rubber sealing tapes 224 can prevent the put-in grinding ball particles from entering the interior of the inner built-in plate shell 221; a grinding inner plate 222. On the side of the outer surface of the grinding inner plate 222 away from the sliding connecting cylinder 214, grinding balls 223 are evenly arranged. The inner cavity of the grinding inner plate 222 is fixedly connected to the interface on the outer surface of the sliding connecting cylinder 214 through a connecting through pipe 225. The outer surface of the grinding inner plate 222 is slidably connected to the inner wall of the inner built-in plate shell 221, and the outer surface of the rubber sealing tape 224 is slidably connected to the outer surface of the grinding inner plate 222. The grinding inner plate 222 is a hollow plate body. The air pressure entering the grinding inner plate 222 from the connecting through pipe 225 will be ejected outward from the nozzles of the grinding inner plate 222. As Figure 8 shown, the nozzle positions are located in the areas between adjacent grinding balls 223.

[0028] The contact component 22 further includes, a side rotating wheel 227. The outer surface of the side rotating wheel 227 is meshed and connected to the outer surface of the grinding inner plate 222 through a rotating cutting groove. On the upper and lower sides of the side rotating wheel 227, control motors 226 are symmetrically arranged through shaft rods, and the outer surface of the control motor 226 is fixedly connected to the outer surface of the inner built-in plate shell 221 through a fixing plate. When the grinding inner plate 222 slides relative to the inner built-in plate shell 221 under the control of the side rotating wheel 227, the rubber sealing tape 224 also slides relative to the outer surface of the grinding inner plate 222, always preventing the grinding ball particles from entering the interior of the inner built-in plate shell 221.

[0029] After placing the butterfly valve inside the docking housing 11, insert the shaft rotating cylinder 211 into the position of the rotating shaft of the built-in turntable 213 for docking. At this time, the shaft rotating cylinder 211 fits against the inner wall part of the butterfly valve through the polished inner plate 222 on the side. Specifically, the grinding balls 223 of the polished inner plate 222 directly contact the inner wall part of the butterfly valve. If the distance between the grinding balls 223 and the inner wall of the butterfly valve is too large, the control motors 226 on both sides can be driven to rotate the side wheels 227, pushing the polished inner plate 222 slightly out of the inner wall of the built-in plate housing 221 by a certain distance, so that the grinding balls 223 contact the inner wall of the butterfly valve. When the grinding balls 223 grind the outer surface of the butterfly valve, the internal shaft rotating cylinder 211 rotates self-driven under the control of the built-in turntable 213. At this time, the polished inner plate 222 grinds the inner wall of the butterfly valve through the grinding balls 223.

[0030] When the shaft rotating cylinder 211 rotates self-driven, the blowers 216 on the upper and lower sides start to alternate in blowing air. The sliding connecting cylinder 214 in the middle starts to move up and down continuously under the impact of the wind force, thereby driving the polished inner plate 222 to slide up and down relative to the built-in plate housing 221 through the elastic connecting sleeve 215, so as to ensure that the grinding balls 223 can completely sweep across the inner wall of the butterfly valve. The wind force of the blowers 216 will enter the hollow polished inner plate 222 through the sliding connecting cylinder 214 and the connecting pipe 225, and spray out in the direction of fitting against the inner wall of the butterfly valve through the through holes of the polished inner plate 222, so as to blow away the debris generated by the grinding work on the inner wall of the butterfly valve. The debris mixes into the pile of grinding balls 223. After the work is completed, the grinding balls 223 can be discharged into the material receiving cylinder 4 for filtering and recycling work.

[0031] Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
