[0039] Please refer to Figure 1 to Figure 2 A CO2 ball valve body surface polishing device comprises: a processing table 1 and a polishing mechanism 2, the polishing mechanism 2 is used for automatically polishing the surface of the ball valve body 4, the polishing mechanism 2 comprises a polishing component 21, a swinging component 22, a rotating component 23 and a positioning component 24; the table top of the processing table 1 is a rectangular plane, the table top is parallel to the horizontal plane, a spatial coordinate system is established with the table top of the processing table 1 as the plane where the X-axis and the Y-axis are located, the length direction of the table top is recorded as the X-axis, the width direction of the table top is recorded as the Y-axis, and the direction perpendicular to the table top of the processing table 1 is recorded as the Z-axis; wherein the rotating component 23 is arranged on the top surface of the processing table 1, which is used to fix the bottom of the ball valve body 4, and can drive the ball valve body 4 to rotate in the plane formed by the X-axis and the Y-axis, so that the polishing component 21 The circumference of the ball valve body 4 is evenly polished; the rotating component 23 includes a rotating motor 231, which is fixedly mounted on the top surface of the processing table 1. The rotating motor 231 can be a reduction motor. The driving end of the rotating motor 231 is fixedly mounted with a clamping seat 232, and the top of the clamping seat 232 is used to clamp with the bottom groove of the ball valve body 4; the positioning component 24 is used to generate downward pressure on the top surface of the ball valve body 4, so that the ball valve body 4 remains in a fixed state during the polishing process; the positioning component 24 includes a support plate 241, which is located directly above the mounting seat 211, one end of which is fixed to one side of the processing table 1, and one end of the support plate 241 is threadedly mounted with a positioning rod 242, and the bottom end of the positioning rod 242 is hemispherical, which is used to contact with the top surface of the ball valve body 4.

[0040] When polishing the ball valve body 4, first install the ball valve body 4 on the positioning component 24. During installation, first engage the card groove at the bottom of the ball valve body 4 with the top of the card seat 232 to keep the ball valve body 4 in a stable state. Then, by rotating the positioning rod 242, the bottom end of the ball valve body 4 is moved down to approach the top surface of the ball valve body 4, and finally contacts the top surface of the ball valve body 4. At this time, under the joint action of the positioning rod 242 and the card seat 232, the ball valve body 4 can be kept in a fixed state, so that the position will not be shifted during the polishing process. The rotating component 23 and the positioning component 24 are used in combination to realize the fixing function of the ball valve body 4, which can not only effectively fix the ball valve body 4, but also make the installation and disassembly operations of the ball valve body 4 more convenient and quick.

[0041] Please refer to Figures 2 to 3 The grinding component 21 is arranged above the top surface of the processing table 1, and one side of the grinding component 21 is rotatably connected to the side of the processing table 1. The grinding component 21 has a telescopic function along the X-axis direction and a rotation function within a plane formed by the Z-axis and the Y-axis. It is used to grind the surface of the ball valve body 4. The grinding component 21 includes a mounting seat 211. The mounting seat 211 is a U-shaped structure. One side of the mounting seat 211 is rotatably connected to the processing table 1. Both left and right ends of the mounting seat 211 are equipped with a telescopic and rotational function. The driving member 212 can be a rotating telescopic cylinder, and its operation is controlled by an external control system. A grinding disc 213 is fixedly installed at one end of the driving member 212. The corresponding grinding disc 213 is driven to rotate and telescope by the driving member 212. A detachable annular grinding disc is installed on the grinding disc 213. When the annular grinding disc rotates, it can contact the surface of the ball valve body 4, thereby increasing the contact opportunity between it and the surface of the ball valve body 4, and the grinding disc can be replaced according to the actual type of the ball valve body 4.

[0042] Please refer to Figures 2 to 3 In order to further increase the number of contacts between the grinding disc 213 and the surface of the ball valve body 4 per unit time, the present invention adds a swinging component 22, specifically: one end of the swinging component 22 is connected to the rotating end of the grinding component 21, which is used to drive the grinding component 21 to swing back and forth in a plane formed by the X-axis and the Z-axis, so that the grinding component 21 evenly grinds the upper and lower ends of the surface of the ball valve body 4; the swinging component 22 includes a swinging motor 221, the swinging motor 221 is fixed to the upper end of the processing table 1, and a driving disc 222 is fixedly installed on its driving end. The swinging motor 221 can be a servo motor, and a driving arm 223 is rotatably installed on one side of the driving disc 222, and the other end of the driving arm 223 is connected to the rotating end of the mounting seat 211.

[0043] After the ball valve body 4 is fixed, the surface thereof is polished. The polishing disc 213 is first driven by the driving member 212 to move horizontally so that the polishing disc contacts the surface of the ball valve body 4. The driving member 212 stops extending. After that, the rotating motor 231 is rotated to drive the clamping seat 232 and the ball valve body 4 to rotate together in the plane formed by the X-axis and the Y-axis. At the same time, the grinding liquid adding mechanism 3 is started to add grinding liquid to the surface of the ball valve body 4. Then, the driving member 212 drives the polishing disc 213 to rotate in the plane formed by the X-axis and the Y-axis so that the polishing disc starts to contact the surface of the ball valve body 4. The surface is rotated and contacted, and then the surface is polished. At the same time, the swing motor 221 rotates, so that the driving plate 222 starts to rotate, and the driving arm 223 starts to swing back and forth following the driving plate 222, which can drive the mounting seat 211 to swing back and forth in the plane formed by the X-axis and the Z-axis. Finally, the polishing plate 213 rotates and swings at the same time. In the process of its swinging, it can make it contact with the surface of the ball valve body 4 more, increase the number of contacts with the surface of the ball valve body 4, so as to improve the polishing effect of the surface of the ball valve body 4, shorten the polishing time, and speed up the polishing speed.

[0044] Example 2

[0045] Please refer to Figures 4 to 5 In order to enable the grinding liquid to be evenly and accurately applied to the surface of the ball valve body 4, the present invention further optimizes the above scheme, specifically: a grinding liquid adding mechanism 3 is provided on the top surface of the processing table 1, and the grinding liquid adding mechanism 3 is used to apply the grinding liquid to the surface of the ball valve body 4. The grinding liquid adding mechanism 3 includes a spraying component 31, a coating component 32 and a movable track 33. The movable track 33 is fixed to the top surface of the processing table 1. The spraying component 31 is slidably connected to the movable track 33. The spraying component 31 can move up and down along the movable track 33, and is used to gradually spray the grinding liquid from one end of the surface of the ball valve body 4 to the other end. The coating component 32 is connected to the spraying component 31, and it is in reciprocating sliding contact with the surface of the ball valve body 4 to evenly spread the grinding liquid sprayed on the surface of the ball valve body 4.

[0046] For details, please refer to Figures 4 to 6The movable track 33 is set as an arc-shaped track plate, and the track plate is tilted and fixed on the top surface of the processing table 1. The tilt direction and tilt angle of the track plate are adapted to the rotation direction and rotation speed of the ball valve body 4, so that the spraying component 31 can follow the rotation movement of the ball valve body 4 and spray the grinding liquid evenly on the surface of the ball valve body 4. The spraying component 31 includes a movable seat 311, a nozzle 312 and a movable assembly. The movable seat 311 is slidably sleeved on the outer side of the movable track 33, and the nozzle 312 is installed on the side of the movable seat 311 facing the ball valve body 4. The nozzle 312 is an atomizing nozzle 312 dedicated to the existing grinding liquid. The input end of the nozzle 312 is connected to the external delivery pump through a flexible tube 313. The movable assembly is connected to the movable seat 311, which is used to drive the movable seat 311 to reciprocate along the setting direction of the movable track 33; the movable assembly includes a transmission motor 314, a transmission gear 315 and an arc-shaped tooth plate 316. The transmission motor 314 is fixed Fixed on one side of the movable seat 311, the transmission motor 314 can be a servo motor, the transmission gear 315 is rotatably installed on the inner side of the movable seat 311, and its rotating end is fixed to the driving end of the transmission motor 314, and the arc-shaped tooth plate 316 is fixedly installed on the inner arc surface of the track plate. One side of the transmission gear 315 is meshed with the arc-shaped tooth plate 316, and one side of the movable track 33 is provided with an arc-shaped limiting groove 317. The inner side of the movable seat 311 is slidably connected with the limiting groove 317 through a sliding shaft. Through the coordinated sliding of the two, the movable seat 311 can be further limited so that it can move stably along the track plate.

[0047] During the grinding process of the ball valve body 4, the grinding liquid is extracted and delivered to the flexible tube 313 by an external delivery pump, and then delivered to the nozzle 312 by the flexible tube 313, and finally sprayed directly on the surface of the ball valve body 4 by the nozzle 312. At the same time, the transmission motor 314 rotates forwardly, which can drive the transmission gear 315 to rotate, so that the transmission gear 315 begins to move slowly downward along the arc-shaped toothed plate 316, and the movable seat 311 and the nozzle 312 begin to slide downward synchronously along the outer side of the track plate. The nozzle 312 moves downward, so that the grinding liquid can be evenly sprayed on the surface of the ball valve body 4. At the same time, the smearing component 32 reciprocates in contact with the surface of the ball valve body 4, so that the sprayed grinding liquid can be evenly spread, so that the grinding liquid can form a grinding liquid layer with uniform thickness at a preset position. Since the track plate is adapted according to the rotating action of the ball valve body 4 When the nozzle 312 is set to an inclined state, the grinding liquid sprayed on the upper and lower ends of the surface of the ball valve body 4 is basically in the same straight line during the downward movement of the nozzle head 312. In this way, when the ball valve body 4 located at the same straight line position contacts the grinding disc 213 at the same time, the grinding liquid can play a grinding effect, which is conducive to avoiding the problem of no grinding liquid at the grinding position. When the transmission gear 315 rotates to the lower end of the arc-shaped tooth plate 316, the transmission motor 314 starts to rotate in the opposite direction, thereby causing the movable seat 311 and the nozzle head 312 to start moving upward, and continue to spray the surface of the next straight line position of the ball valve body 4 evenly. After the transmission gear 315 rotates to the upper end of the arc-shaped tooth plate 316 again, the transmission motor 314 rotates forward again. By repeating this action, the grinding liquid can be evenly and accurately applied to the surface of the ball valve body 4 during the grinding process, so that the grinding liquid can fully play a grinding auxiliary effect.

[0048] It should be noted that the grinding liquid adding mechanism 3 provided in the present invention is different from the existing end-drip type adding mechanism provided on the upper part of the ball valve body 4. It adopts a spraying and active reciprocating spraying method, which can well match the rotation of the ball valve body 4. The grinding liquid can be accurately and evenly applied to the surface to be ground of the ball valve body 4, which can not only make the grinding liquid fully play a grinding auxiliary effect, but also avoid the waste of grinding liquid.

[0049] Please refer to Figures 7 and 8The smearing component 32 includes a transmission assembly and two brush heads 321. The two brush heads 321 are respectively located directly above and directly below the nozzle 312. The brush heads 321 can be made of a flexible material that does not absorb the grinding fluid, such as a rubber material, and the two brush heads 321 are fixed by a connecting rod. One of the brush heads 321 is slidably connected to one side of the movable seat 311. One end of the transmission assembly is connected to the driving end of the transmission motor 314, and the other end is connected to one of the brush heads 321. The transmission assembly is used to drive the brush head 321 to reciprocate in a direction perpendicular to the moving direction of the movable seat 311; the transmission assembly includes a spur plate 322, a swing arm 323, a turntable 324 and two bevel gears 325. The spur plate 322 is fixed to one side of one of the brush heads 321, and the swing arm 323 is rotatably mounted on the movable seat 311. One side of the seat 311 is provided with an arc-shaped tooth segment at one end, and the tooth segment meshes with one side of the straight tooth plate 322. A slide groove 326 is provided at the end of the swing arm 323 away from the straight tooth plate 322. The turntable 324 is rotatably mounted on the side of the movable seat 311 close to the swing arm 323. The top surface of the turntable 324 is slidably connected to the slide groove 326 through a connecting shaft 327. Two bevel gears 325 are respectively fixed to the turntable 324 and the driving end of the transmission motor 314, and one side of the two bevel gears 325 are meshed with each other. The radius of the bevel gear 325 connected to the driving end of the transmission motor 314 can be 1-2 times the radius of the other bevel gear 325. In this way, the differential rotation between the turntable 324 and the transmission gear 315 can be achieved, so that the reciprocating frequency of the brush head 321 is higher, which is convenient for spreading the grinding liquid better.

[0050] When the spray head 312 sprays the grinding liquid onto the surface of the ball valve body 4, the two bevel gears 325 rotate synchronously under the driving action of the transmission motor 314, the turntable 324 is driven by the transmission gear 315 and starts to rotate, the connecting shaft 327 starts to slide in the slide groove 326, so that the swing arm 323 starts to swing back and forth, and the spur plate 322 is driven by the swing arm 323 and starts to slide back and forth on the top surface of the movable seat 311, and the two brush heads 321 follow the spur plate 322 to slide back and forth, and the brush heads 321 reciprocately contact the surface of the ball valve body 4 after the grinding liquid is sprayed. The grinding liquid can be spread quickly and evenly by touching. When the nozzle 312 moves downward, it is mainly spread by the upper brush head 321, and when the nozzle 312 moves upward, it is spread by the lower nozzle 312. During the reciprocating up and down movement of the brush head 321, the other brush head 321 is mainly used to clean the place to be sprayed, and scrape the excess or debris-containing grinding liquid out of the spraying position to facilitate the uniform coating of new grinding liquid, which is beneficial for the new grinding liquid to always contact with the grinding disc 213, thereby better achieving the grinding effect.

[0052] Please refer to Figures 9 and 10In order to spray the grinding liquid more accurately and reduce the waste of grinding liquid, the present invention continues to optimize the above scheme, specifically: the grinding liquid adding mechanism 3 also includes a valve component 34, the valve component 34 includes a conduction head 341, a delivery pipe 342, a movable rod 343 and a plurality of arc-shaped protrusions 344, the conduction head 341 is fixed to one side of the movable seat 311, one end of the delivery pipe 342 is connected to one side of the conduction head 341, and the other end thereof is connected to the nozzle 312, one end of the conduction head 341 is connected to the end of the flexible tube 313, the movable rod 343 is slidably installed on one side of the movable seat 311, one end of the movable rod 343 slides and extends to the inside of the conduction head 341, a reset spring 345 is fixedly installed between the movable rod 343 and the movable seat 311, and a plurality of arc-shaped protrusions 344 are evenly distributed on the outer arc surface of the track plate, and the spacing between the two arc-shaped protrusions 344 is adapted to the spraying diameter of the nozzle 312, and is generally equal to or less than the spraying diameter.

[0053] When the nozzle 312 sprays the grinding liquid, the movable rod 343 moves with the movable seat 311. When one end of the movable rod 343 on the outer side of the movable seat 311 moves and contacts with one of the arc-shaped protrusions 344, the arc-shaped protrusion 344 generates an extrusion force on the movable rod 343, so that the movable rod 343 begins to extend into the conductive head 341, and the return spring 345 is simultaneously squeezed and contracted by the movable rod 343, and finally the end of the movable rod 343 located at the conductive head 341 blocks the liquid inlet of the conductive head 341, so that the grinding liquid in the delivery pipe 342 cannot enter the conductive head 341 temporarily. At this time, the nozzle 312 temporarily stops spraying the grinding liquid. When the end of the movable rod 343 located at the outer side of the movable seat 311 contacts with the arc-shaped protrusion When 344 is separated, the movable rod 343 can be automatically reset under the elastic force of the reset spring 345, the liquid inlet of the conductive head 341 is opened, and the grinding liquid continues to enter the conductive head 341, so that the nozzle 312 can continue to spray the grinding liquid. When the end of the movable rod 343 located on the outer side of the movable seat 311 contacts the next arc-shaped protrusion 344 again, the nozzle 312 stops spraying the grinding liquid again, and repeats this action to realize the function of the nozzle 312 to intermittently spray the grinding liquid synchronously during the movement, which can reduce the repeated spraying of the grinding liquid and achieve the purpose of reducing the waste of the grinding liquid. In addition, the valve component 34 set in the present invention does not need to set up a sensing device and a control program to cooperate to achieve its intermittent control, which can reduce its use cost.

[0054] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
