Description

Technical Field

[0001] This application relates to the field of polishing apparatus, and more specifically, to a ball polishing apparatus for ball valve manufacturing. Background Technology

[0002] Ball valves are widely used control components in industrial pipeline systems. With their characteristics of rapid opening and closing, excellent sealing performance, and low flow resistance coefficient, they occupy an important position in the fields of petroleum, chemical, water treatment, and energy.

[0003] The core control logic of a ball valve is based on the rotational motion of a ball: a ball with a through-hole is located inside the valve body, and the ball is driven by the valve stem to rotate around an axis perpendicular to the flow channel. When the through-hole of the ball coincides with the pipeline axis, the ball valve is in the fully open state, and the medium can pass through without obstruction; when the ball rotates 90 degrees, the through-hole is completely perpendicular to the pipeline axis, the ball valve is in the fully closed state, and the surface of the ball is tightly fitted to the valve seat, achieving medium blockage.

[0004] Therefore, in the ball valve manufacturing process, the ball must be precisely ground and polished, a step that requires specialized polishing equipment. However, ball valves of different specifications differ in parameters such as diameter and curvature, requiring corresponding grinding heads to be replaced. Currently used polishing equipment involves multiple steps when switching between different grinding heads, including disassembling the old head, installing the new head, and readjusting, which is time-consuming and labor-intensive, leading to a decrease in the overall efficiency of ball grinding and polishing. Summary of the Invention

[0005] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a ball polishing device for ball valve production, which can realize the rotary replacement of a tensioning head fixedly connected to a rotating head. Different specifications of tensioning heads are adapted to different balls, and can support balls of different specifications. The tensioning head drives the rotation of the ball, while the rotating end of the second rotating frame drives the rotary replacement of the polishing head to polish balls of different specifications on the upper part of the tensioning head. During the replacement process, no large amount of time is required, which can improve the polishing efficiency.

[0006] A ball polishing device for ball valve production according to an embodiment of this application includes: a frame and a grinding and polishing assembly. The grinding and polishing assembly includes a first rotating frame, a rotating head, a tensioning head, a driving component, a first linear slide rail, a second rotating frame, a pushing component, and a polishing head. Multiple rotating heads and tensioning heads are spaced apart. The tensioning heads are configured with various specifications. The first rotating frame is rotatably connected to one side of the frame. The rotating head is rotatably connected to the rotating end of the first rotating frame. One rotating head is drively connected to the driving end of the driving component. The tensioning head is fixedly connected to the rotating head. The driving end of the driving component is slidably connected to one side of the frame. The sliding end of the first linear slide rail is slidably connected to the frame. The rotating end of the second rotating frame is rotatably connected to the sliding end of the first linear slide rail. Multiple pushing components are provided, with one side of each pushing component fixedly connected to the rotating end of the second rotating frame. Multiple polishing heads of various specifications are provided, with one side of each polishing head slidably connected to the rotating end of the second rotating frame. The pushing end of each pushing component is fixedly connected to one side of each polishing head.

[0007] According to an embodiment of this application, a ball polishing device for ball valve production has the following advantages: In use, the ball is first fitted onto the outside of the tensioning head. The tensioning head applies tension to the ball's through-hole, ensuring the ball is securely mounted on the outside of the tensioning head. Since the rotating head and the first rotating frame are rotatably connected, and the driving end of the drive component is driven by the rotating head, after the drive component is activated, its driving end will drive the rotating head to rotate, thereby causing the ball to rotate synchronously. At this time, the sliding end of the first linear slide rail drives the second rotating frame to move towards the ball, gradually bringing the polishing head, which is compatible with the current ball size, closer to the ball. Simultaneously, the pushing component is activated, and the position of the polishing head is adjusted by the pushing end of the pushing component to ensure that the polishing head is tightly attached to the ball surface. Then, the ball surface polishing operation is carried out. When it is necessary to switch to polishing balls of different sizes, the first linear slide rail... The rotating end of the first rotating frame will start rotating, turning the tensioning head adapted to the new ball to the side closer to the drive component, so that the rotating head connected to the tensioning head is precisely aligned with the drive end of the drive component. At the same time, the rotating end of the second rotating frame will rotate synchronously, turning another polishing head matched with the new ball to the side of the ball. The above actions are repeated. First, the second rotating frame is moved by the sliding end of the first linear slide rail. Then, the position of the polishing head is finely adjusted by the pushing end of the push component, so that the polishing head is once again in contact with the surface of the new ball. Finally, the drive component is activated, and the ball is rotated by the rotating head and the tensioning head, so that the polishing operation of the new specification ball can be started. The entire operation process realizes the automation and rapid replacement of the tensioning head and polishing head, without the need for manual disassembly and reinstallation, which greatly shortens the replacement time and effectively improves the polishing efficiency of the ball.

[0016] According to this application, the pushing member includes a second telescopic member and a push plate, one side of the second telescopic member is fixedly connected to the second frame, and the output end of the second telescopic member is fixedly connected to the push plate.

[0017] According to this application, a fixing plate is provided on one side of the polishing head, the fixing plate is slidably connected to the second frame, and the push plate is fixedly connected to the fixing plate.

[0018] In the production and processing of spheres, polishing is a crucial step in ensuring product precision and surface quality. Currently, the industry commonly uses polishing blocks, but different sphere sizes have different curvatures, resulting in significant size limitations. A single block can only be used to polish one specific size of sphere. More importantly, once these polishing blocks experience significant wear and tear during use and can no longer meet the polishing requirements of the corresponding sphere size, they must be completely disassembled and scrapped. This not only makes it difficult to reuse the polishing blocks but also directly leads to an increased component wear rate, further increasing the material and time costs of the sphere polishing process, and consequently increasing the overall polishing cost.

[0019] According to this application, a repair component is also included, comprising a third linear slide rail, a first lifting frame, a bending frame, a rotating shaft, a repair head, and a cross-section piece. A nut is provided at the bottom of the rotating shaft. Placement slots are spaced apart on one side of the frame. A limit plug is provided at the bottom of the placement slot on the frame. Multiple repair heads of various specifications are provided, each with an insertion hole. The sliding end of the third linear slide rail is slidably connected to the frame. The bottom of the first lifting frame is fixedly connected to the sliding end of the third linear slide rail. One side of the lifting end of the first lifting frame is rotatably connected to one side of the bending frame. The rotating shaft is rotatably connected to one side of the bending frame. The rotating shaft is inserted into the repair head and secured to it by the nut. The repair head is placed inside the placement slot. The limit plug's limiting end slides through the frame and is inserted into the insertion hole. The cross-section piece is slidably connected to one side of the bending frame.

[0020] First, the third linear guide rail is activated, and its sliding end drives the first lifting frame to move horizontally. Then, the lifting end of the first lifting frame drives the bending frame to move vertically. Simultaneously, the bending frame completes a precise bending action according to a preset trajectory. At this point, the rotating shaft is inserted into the central hole of the special repair head and axially locked in place with a nut. The forming surface of this repair head is preset to match the curvature of a sphere increasing by one size, and can be directly used for reshaping the surface of the polishing head. After the repair head and rotating shaft are assembled, the repair head is precisely moved to the corresponding processing side of the polishing head to be repaired through the coordinated action of the third linear guide rail, the first lifting frame, and the bending frame. The rotating shaft drive system drives the repair head to rotate at high speed. The shaped curved surface of the repair head is used to grind the polishing head to be repaired, so that its surface curvature is precisely adapted to the sphere of the increasing size. The cutting end of the cross-cutting part is activated to flatten one side of the repaired polishing head, ensuring that the polishing head will not collide or interfere with the tensioning head in subsequent use. According to the above process, the polishing head can be cyclically repaired and reused for each increasing size. This not only greatly reduces the wear and tear of polishing head components, but also reduces the material cost and downtime cost caused by frequent replacement of new polishing heads in the sphere polishing process, and ultimately achieves effective control of the overall polishing cost.

[0021] According to this application, the third linear slide rail includes a seventh motor, a third lead screw, and a fourth slider. The seventh motor is fixedly connected to the frame, the third lead screw is rotatably connected to the frame, and the fourth slider is slidably connected to the frame. The output end of the seventh motor is fixedly connected to one end of the third lead screw, and the third lead screw is threadedly connected to the fourth slider.

[0022] According to this application, the first lifting frame includes a third frame, a fourth frame, and a third telescopic member. The bottom of the third frame is slidably connected to the interior of the fourth frame. The bottom of the fourth frame and the bottom of the third telescopic member are both fixedly connected to the fourth slider. The output end of the third telescopic member is fixedly connected to the third frame.

[0023] According to this application, the bending frame includes a fifth frame and a fourth telescopic member. An eighth motor is provided on the upper part of the rotating shaft. One side of the fifth frame and the end of the fourth telescopic member are rotatably connected to the third frame. The output end of the fourth telescopic member is rotatably connected to one side of the fifth frame.

The other end of the connecting rod is rotatably connected to one side of the serrated plate. The serrated plate is slidably connected to one side of the fifth frame.

[0024] According to this application, the limiting plug includes a fifth telescopic member and a plug rod. The end of the fifth telescopic member is fixedly connected to the frame, and the output end of the fifth telescopic member is fixedly connected to one side of the plug rod. The plug rod slides through the frame.

[0025] During the polishing process of spheres, in order to avoid the high temperature generated by polishing and grinding affecting the processing accuracy and surface quality of the spheres, it is necessary to continuously spray cooling water to cool the polishing area. However, since the spheres are rotating at high speed, the cooling water sprayed onto the surface of the spheres will be quickly thrown around under the action of centrifugal force, forming a large area of ​​water splash. If a special waterproof structure is not set up for this scenario, the splashed cooling water will spread uncontrollably to the transmission components, electrical components and surrounding work areas inside the equipment. This may not only lead to the risk of equipment component corrosion, electrical system short circuits and other failures, but also damage the cleanliness of the work environment, increasing the difficulty of equipment maintenance and environmental cleanup costs in the later stage.

[0026] According to this application, it also includes a splash-proof assembly, which includes a second lifting frame, a baffle, a sixth linear slide rail, a water-receiving cover, and a nozzle. The bottom of the second lifting frame is fixedly connected to one side of the frame. The baffle is fixedly connected to the lifting end of the second lifting frame. The sliding end of the sixth linear slide rail is slidably connected to the frame. The water-receiving cover is fixedly connected to the sliding end of the sixth linear slide rail. The baffle is located on the outside side of the water-receiving cover. The nozzle is fixedly connected to the water-receiving cover.

[0027] The second lifting frame is activated, and its lifting end drives the baffle to descend vertically, precisely fitting the baffle onto the outside of the rotating head to form the first waterproof protective barrier. Subsequently, the sliding end of the sixth linear slide rail drives the water-collecting cover to move along a preset trajectory until the water-collecting cover completely covers the outside of the ball to be polished. At the same time, it ensures that one side of the water-collecting cover is tightly fitted with the side of the baffle, creating a cooling water collection space. Cooling water is sprayed through the nozzle onto the inner wall of the water-collecting cover, and then flows through the inner wall to cover the surface of the ball, achieving cooling of the polishing area. Even if the ball rotates at high speed and generates centrifugal force, causing the surface cooling water to be thrown outward, the thrown cooling water will still be blocked and collected by the inner wall of the water-collecting cover, preventing it from spreading to the external area. This waterproof structure not only effectively reduces the disorderly splashing of cooling water, fundamentally reducing the risk of damage to the electrical components of the equipment from splashed water droplets, but also significantly improves the cleanliness of the working environment, indirectly reducing the frequency and cost of subsequent equipment maintenance, while also reducing the manpower and material costs required for environmental cleanup.

[0029] According to this application, the sixth linear guide rail includes a ninth motor, an eighth lead screw, and an eighth slider. The ninth motor is fixedly connected to the frame, the output end of the ninth motor is fixedly connected to one end of the eighth lead screw, the eighth lead screw is rotatably connected to the frame, the eighth lead screw is threadedly connected to the eighth slider, the eighth slider is slidably connected to the frame, and the water-receiving cover is fixedly connected to the eighth slider.

Detailed Implementation

[0045] The following description, with reference to the accompanying drawings, describes a ball polishing apparatus for ball valve production according to an embodiment of this application.

[0046] like Figures 1-13 As shown, a ball polishing apparatus for ball valve production according to an embodiment of this application includes a frame 100 and a grinding and polishing assembly 200.

[0047] The polishing assembly 200 includes a first rotating frame 210, a rotating head 220, a tensioning head 230, a driving component 240, a first linear slide rail 250, a second rotating frame 260, a pushing component 270, and a polishing head 280. Multiple rotating heads 220 and tensioning heads 230 are spaced apart. The tensioning heads 230 are configured in various specifications. The first rotating frame 210 is rotatably connected to one side of the frame 100. The rotating head 220 is rotatably connected to the rotating end of the first rotating frame 210. One rotating head 220 is connected to the driving end of the driving component 240. The tensioning head 230 is connected to... The rotating head 220 is fixedly connected, the driving end of the driving component 240 is slidably connected to one side of the frame 100, the sliding end of the first linear slide rail 250 is slidably connected to the frame 100, the rotating end of the second rotating frame 260 is rotatably connected to the sliding end of the first linear slide rail 250, multiple pushing components 270 are provided, one side of the pushing component 270 is fixedly connected to the rotating end of the second rotating frame 260, multiple polishing heads 280 are provided and are of various specifications, one side of the polishing head 280 is slidably connected to the rotating end of the second rotating frame 260, and the pushing end of the pushing component 270 is fixedly connected to one side of the polishing head 280.

[0048] The working process of a ball polishing apparatus for ball valve production according to a specific embodiment of this application is described below with reference to the accompanying drawings.

[0049] First, the ball to be polished is placed on the outside of the tension head 230. Then, the output end of the first telescopic component 111 pushes the first slider 112 to move, driving the second motor 120 and the tightening head 121 to approach the tension head 230, so that the tightening head 121 is precisely placed on the outside of the nut head 237 of the bidirectional threaded rod 232. Then, the output end of the second motor 122 drives the bidirectional threaded rod 232 to rotate, and the two threaded blocks 233 move relative to each other along the bidirectional threaded rod 232. The first rod body 234 pushes the second rod body 235 to unfold outward, and finally the anti-slip head 236 at the end of the second rod body 235 is tightly pressed against the groove inside the ball, thus completing the stable fixation of the ball.

[0050] Then, after the sphere is fixed, the output end of the fourth motor 242 drives the first lead screw 243 to rotate, causing the second slider 244 to slide along the frame 100 until the third gear 221 of the rotating head 220 meshes with the second gear 246 on the second slider 244. Subsequently, the output end of the third motor 241 drives the rotating head 220 and the sphere to rotate synchronously through the transmission of the first gear 245, the second gear 246 and the third gear 221. At the same time, the output end of the fifth motor 251 drives the second lead screw 252 to rotate, causing the third slider 253 and the second rotating frame 260 to move towards the sphere. The output end of the second telescopic member 271 extends, pushing the polishing head 280 to fit against the surface of the sphere through the push plate 272 and the fixed sleeve plate 281, realizing the polishing operation in the rotating state.

[0051] Next, when polishing spheres of different sizes, the size adaptation component is switched first. The first motor 211 is started, and its output end is driven by the first gear ring 214 of the first frame 212 through the fourth gear 213, which drives the first frame 212 to rotate. The tension head 230 adapted to the new size sphere is rotated to the side close to the drive member 240, so that the third gear 221 of the corresponding rotating head 220 can be connected to the second gear 246. At the same time, the sixth motor 261 is started, and its output end is driven by the second gear ring 264 of the second frame 262 through the fifth gear 263, which drives the second frame 262 to rotate. The polishing head 280 adapted to the new size sphere is rotated to the corresponding position. Then, the sphere fixing operation in step one and the polishing operation in step two are repeated to achieve continuous polishing of spheres of different sizes.

[0052] Thus, the entire operation process achieves automated and rapid replacement of the tensioning head 230 and the polishing head 280, eliminating the need for manual disassembly and reinstallation, significantly reducing the time spent on replacement parts, and effectively improving the polishing efficiency of the sphere.

[0053] In addition, a ball polishing apparatus for ball valve production according to an embodiment of this application also has the following additional technical features:

[0063] In the production and processing of spheres, polishing is a crucial step in ensuring product precision and surface quality. Currently, the industry commonly uses polishing blocks, but different sphere sizes have different curvatures, resulting in significant size limitations. A single block can only be used to polish one specific size of sphere. More importantly, once these polishing blocks experience significant wear and tear during use and can no longer meet the polishing requirements of the corresponding sphere size, they must be completely disassembled and scrapped. This not only makes it difficult to reuse the polishing blocks but also directly leads to an increased component wear rate, further increasing the material and time costs of the sphere polishing process, and consequently increasing the overall polishing cost.

[0064] According to this application, such as Figures 9-12As shown, it also includes a repair component 300, which includes a third linear slide rail 310, a first lifting frame 320, a bending frame 330, a rotating shaft 340, a repair head 350, and a cross-section piece 360. A nut 341 is provided at the bottom of the rotating shaft 340. Placement slots 130 are spaced apart on one side of the frame 100. A limit plug 140 is provided at the bottom of the placement slots 130 on the frame 100.

[0065] Insert the rotating shaft 340 into the central hole of the special repair head 350. At this time, the fifth telescopic component 141 drives the insertion rod 142 to be pulled out from the insertion hole 351 of the repair head 350, releasing the limit on the repair head 350. The rotating end of the rotating shaft 340 rotates, connecting the nut 341 at the bottom of the repair head 350 to the rotating shaft 340 with a thread, locking the polishing head 280. Then, the lifting end of the first lifting frame 320 drives the bending frame 330 to rise, raising the polishing head 280. Head 280 is removed from the placement slot 130. Then, the output of the seventh motor 311 of the third linear slide rail 310 drives the third lead screw 312 to rotate, causing the fourth slider 313 and the first lifting frame 320 above it to move horizontally. The third telescopic component 323 of the first lifting frame 320 pushes the third frame 321 up or down along the fourth frame 322, adjusting the height of the bending frame 330. Simultaneously, the fourth telescopic component 332 of the bending frame 330 pushes the fifth frame 331 back to its original position, assembling... The repair head 350 is transferred to the processing side of the polishing head 280 to be repaired. The eighth motor 342 on the upper part of the rotating shaft 340 is started, and its output end drives the repair head 350 to rotate at high speed. Using the pre-set incremental specification ball matching curvature of the repair head 350, the surface of the polishing head 280 to be repaired is ground to make its curvature accurately fit the new specification ball. Then, the cross-cutting piece 360 ​​is started, slides along the bending frame 330 and flattens one side of the repaired polishing head 280 to avoid collision and interference with the tensioning head 230 during subsequent use. Finally, the repair and specification adaptation of the polishing head 280 are completed, realizing the cyclic reuse of the polishing head 280. According to the above process, the polishing head 280 can be repaired and reused in cycles of increasing one specification each time. This not only greatly reduces the wear and tear of the polishing head 280 components, but also reduces the material cost and downtime cost caused by frequent replacement of the new polishing head 280 in the ball polishing process, and finally achieves effective control of the overall polishing cost.

[0070] According to this application, such as Figure 12 As shown, the limiting plug 140 includes a fifth telescopic member 141 and a plug rod 142. The end of the fifth telescopic member 141 is fixedly connected to the frame 100, and the output end of the fifth telescopic member 141 is fixedly connected to one side of the plug rod 142. The plug rod 142 slides through the frame 100.

[0071] During the polishing process of spheres, in order to avoid the high temperature generated by polishing and grinding affecting the processing accuracy and surface quality of the spheres, it is necessary to continuously spray cooling water to cool the polishing area. However, since the spheres are rotating at high speed, the cooling water sprayed onto the surface of the spheres will be quickly thrown around under the action of centrifugal force, forming a large area of ​​water splash. If a special waterproof structure is not set up for this scenario, the splashed cooling water will spread uncontrollably to the transmission components, electrical components and surrounding work areas inside the equipment. This may not only lead to the risk of equipment component corrosion, electrical system short circuits and other failures, but also damage the cleanliness of the work environment, increasing the difficulty of equipment maintenance and environmental cleanup costs in the later stage.

[0072] According to this application, such as Figure 13 As shown, it also includes a splash-proof assembly 400, which includes a second lifting frame 410, a baffle 420, a sixth linear slide rail 430, a water-receiving cover 440, and a nozzle 450. The bottom of the second lifting frame 410 is fixedly connected to one side of the frame 100. The baffle 420 is fixedly connected to the lifting end of the second lifting frame 410. The sliding end of the sixth linear slide rail 430 is slidably connected to the frame 100. The water-receiving cover 440 is fixedly connected to the sliding end of the sixth linear slide rail 430. The baffle 420 is located on the outside of the water-receiving cover 440. The nozzle 450 is fixedly connected to the water-receiving cover 440.

[0073] The telescopic end of the eighth telescopic component 413 of the second lifting frame 410 retracts, causing the eighth frame 411 to slide downwards along the ninth frame 412. This causes the baffle 420, which is fixed to the eighth frame 411, to move vertically until the baffle 420 is precisely fitted onto the outside of the rotating head 220, forming a preliminary waterproof protective barrier. Then, the output end of the ninth motor 431 of the sixth linear slide rail 430 drives the eighth lead screw 432 to rotate, causing the eighth slider 433, which is threaded to it, to slide along the frame 100. This causes the water-collecting cover 440, which is fixed to the eighth slider 433, to move synchronously until the water-collecting cover 440 completely covers the outside of the ball to be polished, and one side of the water-collecting cover 440 is tightly fitted with the side of the baffle 420, together forming a cooling water collection space. Subsequently, cooling water is sprayed onto the inner wall of the water receiving cover 440 via a nozzle 450 fixed to the water receiving cover 440, and then flows along the inner wall to cover the surface of the sphere, cooling the polishing area. When the sphere rotates at high speed and generates centrifugal force to throw the surface cooling water outward, the thrown cooling water is blocked and collected by the inner wall of the water receiving cover 440, preventing it from spreading to the external area. At the same time, the baffle 420 further prevents cooling water from splashing from the gap between the rotating head 220 and the water receiving cover 440, ultimately achieving the dual functions of splash prevention and cooling. This reduces the risk of damage to the electrical components of the equipment from splashing water droplets, significantly improves the cleanliness of the working environment, indirectly reduces the frequency and cost of subsequent equipment maintenance, and also reduces the manpower and material costs required for environmental cleaning.

The baffle 420 is fixedly connected to one side of the eighth frame 411.
