A special machine for turning and grinding butterfly valve bodies

Abstract

The present invention belongs to the field of lathing and grinding technology, specifically a special machine for lathing and grinding butterfly valve bodies, comprising a closing cover component for placing butterfly valves that need to be polished, and the interior of the closing cover component is filled with polishing balls; an inner grinding component for polishing the inner wall of the butterfly valve; and a material container, which is arranged directly below the closing cover component and is used to hold the waste material after polishing. The device can polish the outer surface of the butterfly valve limited by the axis limit ring through the tiny polishing balls filled in the interior of the closing cover component. Since the polishing balls are small and their positions are constantly changed with the flipping movement of the closing cover component, it is ensured that the polishing balls can fully and effectively contact the outer surface of the butterfly valve. For butterfly valves with many concave and convex surfaces, the dead corners can be effectively polished, thereby eliminating the burrs on the outer surface of the convex or concave parts of the butterfly valve, and avoiding the problem of a large amount of burrs remaining on the outer surface of the butterfly valve.

Description

Technical Field

[0001] The invention belongs to the technical field of turning and grinding, in particular to a special machine for turning and grinding a butterfly valve body. Background Art

[0002] A butterfly valve, also known as a flap valve, is a regulating valve with a simple structure. It can be used for on-off control of low-pressure pipeline media. A butterfly valve refers to a valve disc or butterfly plate that rotates around the 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, liquid metal and radioactive media. It mainly plays a cutting and throttling role in the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulation.

[0003] The existing publication number is CN117961689A, which is a butterfly valve body grinding device and a grinding method. The top grinding disc of the first motor and the bottom grinding disc of the second motor are used to simultaneously grind the upper and lower surfaces of the butterfly valve body, thereby achieving high-efficiency grinding of the butterfly valve body. However, the outer surface of the actual butterfly valve component is not a flat surface. Directly using the grinding disc cannot effectively grind the raised or recessed parts of the butterfly valve, and the outer surface of the final finished butterfly valve still contains a large number of burrs, so improvement work is needed. Summary of the Invention

[0004] Aiming at the problem that the existing technology easily overlooks the burrs on the outer surface of the butterfly valve during grinding, the technical solution adopted by the present invention is: a butterfly valve body grinding machine, comprising:

[0005] The cover part is used to place the butterfly valve that needs to be polished, and the interior of the cover part is filled with polishing balls;

[0006] Internal grinding parts, used to grind the inner wall of the butterfly valve;

[0007] The material holding barrel is arranged just below the cover part and is used to hold the waste materials after grinding;

[0008] The cover closing component comprises:

[0009] There are two docking shells, and an axis limit ring is opened at the axis center of the inner wall of the docking shell. After the butterfly valve is placed inside the docking shell, the circular groove at its center is sleeved on the axis limit ring, which plays a role in limiting the movement of the butterfly valve;

[0010] The material delivery pipe is set in the inner cavity of the docking shell through the through-hole, and the inner cavity of the material delivery pipe is provided with a plug. After the interior of the docking shell is filled with fine grinding balls through the material delivery pipe, the material delivery pipe is blocked with the plug.

[0011] An extended bottom shell, the extended bottom shell being arranged at the axis center of the outer surface of the docking shell;

[0012] The inner grinding component comprises:

[0013] The contact part is used for direct contact and friction with the arc-shaped inner wall of the butterfly valve;

[0014] The control component directly drives the contact components to rotate and slide.

[0015] Furthermore,

[0016] The flip component is directly connected to the cover closing component and is used to control the rotation of the cover closing component and the internal butterfly valve;

[0017] The flip component has:

[0018] Side frames, the number of which is two, are set on the ground, and torque motors are symmetrically arranged on both sides of the outer surface of the side frames;

[0019] A transmission twist wheel, wherein the axis center of the inner wall of the transmission twist wheel is plugged into the output shaft of the torque motor;

[0020] A transmission belt, wherein both sides of the inner wall of the transmission belt are in rolling connection with the outer surface of the transmission twist wheel, and the interior of the transmission belt is stretched and shaped by the plate body;

[0021] An axial wheel, the outer surface of which is in rolling connection with the middle portion of the inner wall of the transmission belt, and the axial wheel is arranged at the center position through the skeleton plate inside the transmission belt, and rotates under the friction of the transmission belt;

[0022] The plug-in component is used to connect the shaft wheel and the cover component.

[0023] Furthermore, the plug-in component includes:

[0024] Filling shaft, the outer surface of the filling shaft is symmetrically provided with vertical plugs on both sides, the inner cavity of the vertical plug is evenly provided with elastic joints, the elastic joints are as follows Figure 5 As shown, the compression cylinder in the middle can be extended under the control of an external remote control, so that the elastic joints at both ends are inserted into the docking notches of the docking shell, thereby ensuring the connection of the vertical plug-in board. The outer surface of the vertical plug-in board is plugged into the inner cavity of the docking shell through the docking notch. The outer surface of the elastic joint is plugged into the inner cavity of the docking shell through the docking notch. The upper and lower docking shells are connected and merged into a complete sealing shell by a filling shaft, covering the internal butterfly valve.

[0025] A fixed end head, the outer surface of which is fixedly connected to the inner cavity of the filling shaft through the accommodating groove.

[0026] Furthermore, the flip component further includes:

[0027] A connecting rod, one end of which is fixedly connected to the axis of the inner wall of the axis wheel, and the other end of which is rotatably connected to the inner cavity of the filling shaft through the receiving groove;

[0028] An elastic ring, the inner wall of which is sleeved with the side of the outer surface of the connecting rotating rod away from the axis rotating wheel;

[0029] The docking pressure rod is evenly arranged at the end of the connecting rod away from the axis rotating wheel, and the outer surface of the docking pressure rod and the outer surface of the fixed end are squeezed 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.

[0030] Furthermore, the control component includes:

[0031] A shaft rotating drum, wherein the inner cavity of the shaft rotating drum is uniformly provided with vertical grooves, and the outer surface of the shaft rotating drum is plugged into the inner wall of the shaft limiting ring;

[0032] A built-in turntable, wherein the outer surface of the built-in turntable output shaft 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;

[0033] The sliding connecting tube has elastic sleeves symmetrically arranged at the upper and lower ends of the sliding connecting tube. 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. After the shaft of the built-in turntable is inserted into the docking port at the axis center outside the sliding connecting tube, the built-in turntable can directly drive the sliding connecting tube to rotate.

[0034] The blower has an axis on its outer surface fixedly connected to the end of the elastic sleeve away from the sliding tube. The outer surface of the blower 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.

[0035] Furthermore, the contact component includes:

[0036] The outer surface of the built-in plate shell is fixedly connected to the inner cavity of the axis rotating cylinder through a vertical groove. The inner wall of the built-in plate shell is symmetrically provided with a rubber sealing belt on the side away from the sliding connecting tube. The rubber sealing belt can prevent the polishing ball particles from entering the interior of the built-in plate shell;

[0037] The grinding inner plate has grinding balls evenly arranged on the side of the outer surface of the grinding inner plate 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. The air pressure entering the grinding inner plate from the connecting pipe will be ejected outward from the nozzle of the grinding inner plate. Figure 8 As shown, the nozzle is located in the area between adjacent grinding balls.

[0038] Furthermore, the contact component further includes:

[0039] The side rotating wheel, the outer surface of the side rotating wheel is meshed and connected with the outer surface of the polished inner plate through a rotating groove, and the upper and lower sides of the side rotating wheel are symmetrically provided with control motors through the shaft, and the outer surface of the control motor is fixedly connected with the outer surface of the built-in plate shell through the fixed plate. When the polished inner plate slides relative to the built-in plate shell under the control of the side rotating wheel, the rubber sealing belt also slides relative to the outer surface of the polished inner plate, always preventing the polishing ball particles from entering the interior of the built-in plate shell.

[0040] The beneficial effects of the present invention are as follows:

[0041] 1. The device can grind the outer surface of the butterfly valve limited by the axis limit ring through the tiny grinding balls filled inside the closing part. Since the grinding balls are small and their positions are constantly changed with the flipping movement of the closing part, it ensures that the grinding balls can fully and effectively contact the outer surface of the butterfly valve. For butterfly valves with many concave and convex surfaces, the dead angles can be effectively polished, thereby eliminating the burrs on the outer surface of the convex or concave parts of the butterfly valve and avoiding the problem of a large amount of burrs remaining on the outer surface of the butterfly valve.

[0042] 2. In order to avoid the problem that the grinding balls inside the closing part gather on one side due to centrifugal rotation, which reduces the possibility of the grinding balls contacting the butterfly valve, during the process of the flipping part controlling the flipping of the closing part, the principle of slippage between the connecting rod and the filling shaft is used to make the closing part continuously move in the left and right directions, thereby breaking up the grinding balls gathered due to centrifugal force, making the movement of the grinding balls irregular, and greatly increasing the probability of contact with the outer surface of the butterfly valve. Not only can effective grinding work be achieved, but the efficiency of ball grinding will also be improved.

[0043] 3. The inner wall of the butterfly valve does not contact the grinding balls inside the docking shell, so it is necessary to use internal grinding parts to grind 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 types, the grinding inner plate is designed to be a propulsive structure to ensure that when the grinding balls rotate relative to the butterfly valve, the inner wall of the butterfly valve can be ground through friction. When the grinding inner plate rotates, it also slides up and down relative to the built-in plate shell, thereby achieving the effect of fully grinding the inner wall of the butterfly valve with fewer grinding balls. As the number of grinding balls decreases, 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 be used for grinding for a long time.

[0044] 4. When the axis drum rotates, the blowers on the upper and lower sides start to blow air alternately. The wind from the blowers will enter the hollow polished inner plate through the sliding tube and the connecting pipe, and will be ejected through the opening of the polished inner plate in the direction of the inner wall of the butterfly valve, thereby blowing away the debris generated by the polishing work on the inner wall of the butterfly valve, and avoiding the debris polished by the grinding ball adhering to the outer surface of the axis drum, which will cause the axis drum to be unable to rotate smoothly.

After the butterfly valve is placed inside the docking shell 11, the circular groove at the center is sleeved on the axis limit ring 13, which plays a role in limiting the movement of the butterfly valve;

[0061] The material delivery pipe 12 is provided in the inner cavity of the docking shell 11 through a through-hole, and the inner cavity of the material delivery pipe 12 is provided with a plug. After the interior of the docking shell 11 is filled with fine grinding balls through the material delivery pipe 12, the material delivery pipe 12 is blocked with the plug.

[0062] The extended bottom shell 14 is arranged at the axis center of the outer surface of the docking shell 11;

[0063] The inner grinding part 2 includes:

[0064] The contact component 22 is used for directly contacting and rubbing with the arc-shaped inner wall of the butterfly valve;

[0065] The control component 21 directly drives the contact component 22 to rotate and slide.

[0066] Also includes,

[0067] The flip component 3 is directly connected to the cover closing component 1 and is used to control the rotation of the cover closing component 1 and the internal butterfly valve;

[0068] The flip part 3 has:

[0069] Side frames 31, there are two sets of side frames 31, which are set on the ground, and torque motors are symmetrically arranged on both sides of the outer surface of the side frames 31;

[0070] The transmission twist wheel 32 has an inner wall whose axis is connected to the output shaft of the torque motor;

[0071] The transmission belt 33 has two sides of its inner wall in rolling connection with the outer surface of the transmission wheel 32, and the interior of the transmission belt 33 is stretched and shaped by the plate;

[0072] The shaft wheel 34 has an outer surface that is in rolling connection with the middle portion of the inner wall of the transmission belt 33. The shaft wheel 34 is arranged at the center position through the skeleton plate inside the transmission belt 33 and rotates under the friction of the transmission belt 33.

[0073] The plug-in component 5 is used to connect the shaft wheel 34 and the cover component 1.

[0074] The plug-in component 5 includes:

[0075] Filling shaft 51, the outer surface of the filling shaft 51 is symmetrically provided with vertical inserts 52 on both sides, the inner cavity of the vertical inserts 52 is evenly provided with elastic joints 53, the elastic joints 53 are as follows Figure 5As shown, the compression cylinder in the middle can be extended under the control of an external remote control, so that the elastic joints 53 at both ends are inserted into the docking notches 15 of the docking shell 11, thereby ensuring the connection of the vertical plug plate 52. The outer surface of the vertical plug plate 52 is plugged into the inner cavity of the docking shell 11 through the docking notches 15. The outer surface of the elastic joint 53 is plugged into the inner cavity of the docking shell 11 through the docking notches 15. The upper and lower docking shells 11 are connected and merged into a complete shell by the filling shaft 51, covering the internal butterfly valve.

[0076] The fixed end 55 has an outer surface fixedly connected to the inner cavity of the filling shaft 51 through the accommodating groove 54 .

[0077] The turning part 3 also includes,

[0078] A connecting rod 35, one end of which is fixedly connected to the axis of the inner wall of the axis wheel 34, and the other end of which is rotatably connected to the inner cavity of the filling shaft 51 through the receiving groove 54;

[0079] An elastic ring 37, the inner wall of which is sleeved with the outer surface of the connecting rod 35 on a side away from the shaft wheel 34;

[0080] The docking pressure rod 36 is evenly arranged at the end of the connecting rotating rod 35 away from the axial rotating wheel 34, and the outer surface of the docking pressure rod 36 and the outer surface of the fixed end 55 are squeezed against each other. When the docking pressure rod 36 and the fixed end 55 are staggered, under the elastic force of the elastic ring 37, the connecting rotating rod 35 will be slightly inserted into the depth of the accommodating groove 54, thereby achieving the effect of side pushing the filling shaft rod 51 and the docking shell 11.

[0081] The control component 21 includes,

[0082] The inner cavity of the shaft rotating cylinder 211 is uniformly provided with vertical grooves 212, and the outer surface of the shaft rotating cylinder 211 is plugged into the inner wall of the shaft limiting ring 13;

[0083] The outer surface of the output shaft of the built-in turntable 213 is plugged into the axis of the outer surface of the axis rotating cylinder 211, and the outer surface of the built-in turntable 213 is fixedly connected to the axis of the inner wall of the extended bottom shell 14;

[0084] The sliding connecting tube 214 has elastic sleeves 215 symmetrically provided at its upper and lower ends. The air pressure entering from the upper and lower ends of the sliding connecting tube 214 is discharged outward through the side openings of the sliding connecting tube 214. After the shaft of the built-in rotating disk 213 is inserted into the docking port at the axis center outside the sliding connecting tube 214, the built-in rotating disk 213 can directly drive the sliding connecting tube 214 to rotate.

[0085] Blower 216, the axis of the outer surface of the blower 216 is fixedly connected to the end of the elastic sleeve 215 away from the sliding connection 214, and the outer surface of the blower 216 is fixedly connected to the inner wall of the axial rotating cylinder 211. When there is a difference in the wind force of the blowers 216 on the upper and lower sides, the sliding connection 214 will be blown by the blower 216 on the side with greater wind force, and then slide to a position close to the blower 216 on the other side.

[0086] After opening the closing cover part 1, insert it into the center position of the butterfly valve with the axial limit ring 13 as the center, and then connect the flip parts 3 on both sides to the docking shell 11 through the plug-in parts 5, that is, put the filling shaft 51 into the docking groove 15, and insert the vertical plug plate 52 at the bottom of the filling shaft 51 into the docking groove 15. Then place the upper docking shell 11, and also insert the upper vertical plug plate 52 into the docking groove 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 insert the elastic joint 53 into the preset groove deep in the docking groove 15 to form a relatively closed closing cover part 1.

[0087] Block the material delivery pipe 12 of the lower docking shell 11, and fill the interior of the cover part 1 with fine grinding balls through the material delivery pipe 12 of the upper docking shell 11. After adding an appropriate amount of grinding balls, block the material delivery pipe 12 of the upper docking shell 11 to complete the preparation work.

[0088] The side frame 31 drives the transmission twist wheel 32 and the transmission belt 33 to rotate through the motor, so that the axial wheels 34 on both sides can synchronously twist the connecting rod 35, and then drive the filling shaft 51 to rotate under the action of friction. Since the filling shaft 51 is tightly connected to the closing cover part 1 at this time, the docking shell 11 also rotates. Since the butterfly valve is limited by the axial limit ring 13 inside the docking shell 11, the butterfly valve will not collide with the inner wall of the docking shell 11, but the polishing balls inside the docking shell 11 will continuously contact the outer surface of the butterfly valve at high frequency during the continuous flipping process, thereby achieving a polishing effect.

[0089] When the rotation speed of the connecting rotating rod 35 is relatively high, the connecting rotating rod 35 will slip with the filling shaft rod 51, causing the docking pressure rod 36 and the fixed end 55 to rotate in an offset manner, thereby causing the docking pressure rod 36 to continuously push the closing cover component 1 through the fixed end 55. At this time, during the axial rotation of the closing cover component 1, the closing cover component 1 also continuously shakes in the left and right directions, so that the internal grinding balls will not move only under the action of centrifugal rotation, thereby making the movement of the grinding balls irregular, avoiding the problem of unilateral offset of the grinding balls on the inner wall of the closing cover component 1 due to centrifugal force.

[0090] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: Based on embodiment 1, the contact component 22 includes:

[0091] The outer surface of the built-in plate shell 221 is fixedly connected to the inner cavity of the axis rotating cylinder 211 through the vertical groove 212. The inner wall of the built-in plate shell 221 is symmetrically provided with a rubber sealing band 224 on the side away from the sliding connecting tube 214. The rubber sealing band 224 can prevent the polishing ball particles from entering the interior of the built-in plate shell 221;

[0092] The grinding inner plate 222 has grinding balls 223 evenly arranged on the side of the outer surface of the grinding inner plate 222 away from the sliding connecting tube 214. The inner cavity of the grinding inner plate 222 is fixedly connected to the interface of the outer surface of the sliding connecting tube 214 through the connecting tube 225. The outer surface of the grinding inner plate 222 is slidably connected to the inner wall of the built-in plate shell 221, and the outer surface of the rubber sealing belt 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 tube 225 will be ejected outward from the nozzle of the grinding inner plate 222. Figure 8 As shown, the nozzle is located in the area between adjacent grinding balls 223.

[0093] The contact component 22 further includes,

[0094] The side rotating wheel 227, the outer surface of the side rotating wheel 227 is meshed with the outer surface of the grinding inner plate 222 through a rotating groove, and the upper and lower sides of the side rotating wheel 227 are symmetrically provided with a control motor 226 through an axis rod, and the outer surface of the control motor 226 is fixedly connected to the outer surface of the built-in plate shell 221 through a fixed plate. When the grinding inner plate 222 slides relative to the built-in plate shell 221 under the control of the side rotating wheel 227, the rubber sealing belt 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 built-in plate shell 221.

[0095] After the butterfly valve is placed inside the docking shell 11, the axis rotating drum 211 is inserted into the axis position of the docking built-in turntable 213. At this time, the axis rotating drum 211 is fitted with the inner wall of the butterfly valve through the side grinding inner plate 222. Specifically, the grinding balls 223 of the grinding inner plate 222 directly contact the inner wall of the butterfly valve. If the distance between the grinding balls 223 and the inner wall of the butterfly valve is too large, the side wheels 227 can be driven to rotate by the control motors 226 on both sides to push the grinding inner plate 222 slightly out of the inner wall of the built-in plate shell 221 for a 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 axis rotating drum 211 rotates under the control of the built-in turntable 213. At this time, the grinding inner plate 222 grinds the inner wall of the butterfly valve through the grinding balls 223.

[0096] When the axial drum 211 rotates, the blowers 216 on the upper and lower sides begin to blow air alternately, and the sliding connecting tube 214 in the middle begins to move up and down continuously under the impact of the wind, thereby driving the grinding inner plate 222 to slide up and down relative to the built-in plate shell 221 through the elastic connecting sleeve 215, thereby ensuring that the grinding balls 223 can completely sweep the inner wall of the butterfly valve, and the wind force of the blower 216 will enter the hollow grinding inner plate 222 through the sliding connecting tube 214 and the connecting pipe 225, and be ejected in the direction of the inner wall of the butterfly valve through the opening of the grinding inner plate 222, thereby blowing away the debris generated by the grinding work on the inner wall of the butterfly valve, and the debris is mixed into the pile of grinding balls 223. After the work is completed, the grinding balls 223 can be discharged into the material holding barrel 4 for filtration and recovery.

[0097] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
