Description

Technical Field

[0001] This invention relates to the technical field of butterfly valve body processing equipment, specifically a multi-station butterfly valve processing system. Background Technology

[0002] Butterfly valve body processing equipment refers to specialized mechanical equipment and tooling systems used for manufacturing processes such as forming, cutting, grinding, welding and testing of butterfly valve bodies. It typically integrates clamping and fixing mechanisms, power actuation units and auxiliary systems.

[0003] Currently, butterfly valve body processing generally adopts a traditional multi-machine-tool segmented and separate processing scheme. Each processing step is isolated and independent: rough turning, finish turning, drilling, sealing surface milling, grinding and dimensional inspection of the blank are completed on different equipment. The workpiece needs to be transferred between multiple machine tools for segmented processing. There is a lot of waiting time and material transfer time between processes, and the continuity of the processing flow is insufficient, which greatly extends the overall production cycle of the product and ultimately reduces the overall production efficiency of valve body processing.

[0022] Please see Figure 1-12 The present invention provides a technical solution: a multi-station processing system for butterfly valves, comprising: A base plate 1 and a multi-station machining assembly 2 are fixedly installed on one side of the outer surface of the base plate 1 near the edge.

A first connecting rod 303 is fixedly connected to both sides of the outer surface of cover plate 302 near the two sides; driven clamping component 4 is set inside processing positioning component 3. Driven clamping component 4 includes multiple support shafts 401. A connecting block 402 is fixedly connected to one end of each of the multiple support shafts 401.Rotating assembly 5 is installed on one side of the outer surface of base plate 1 at its center. Two opposing brushes 208 are fixedly installed on both sides of the outer surfaces of multiple processing boxes 202. A first slide rail 304 is fixedly connected to one side of the outer surface of each of the two first connecting rods 303. A second connecting rod 305 is fixedly connected to one side of the outer surface of the cover plate 302 near the other two edges. A second slide rail 306 is fixedly connected to one side of the outer surface of each of the two second connecting rods 305. Connecting shafts 307 are slidably connected to the inner walls of the two first slide rails 304. The outer surfaces of the two connecting shafts 307... Two opposing first movable plates 310 are fixedly connected to one end of each of the four surfaces. Clamping plates 308 are fixedly connected to the other ends of each of the two connecting shafts 307. Clamping plates 309 are fixedly connected to one outer surface of each of the two clamping plates 308. First rotating shafts 311 are fixedly embedded in the inner walls of each of the four first movable plates 310. Movable rods 312 are movably sleeved on the outer surfaces of each of the four first rotating shafts 311 near both ends. Sliding cylinders 313 are slidably connected inside each of the two second slide rails 306. Two opposing second movable rods 313 are fixedly connected to the outer surfaces of each of the two slide cylinders 313. Plate 314, two sliding shafts 411, and movable cylinders 417 are fixedly sleeved on the outer surfaces near one end of each other. Four second connecting plates 320 are grouped in pairs, with the outer surfaces of the two groups of second connecting plates 320 respectively fixedly connected to the outer surfaces of the two movable cylinders 417. The rotating assembly 5 includes a seat shaft 501, one end of which is fixedly connected to the other outer surface of the turntable 301 at its center, and the other end of which is rotatably connected to the inner wall of the base plate 1 at its center. A support plate 507 is fixedly connected to one outer surface of the base plate 1 near its center. A sleeve plate 502 is fixedly connected to one outer surface of plate 507. The inner wall of sleeve plate 502 is rotatably connected to the outer surface of seat shaft 501. A motor 503 is fixedly connected to the outer surface of sleeve plate 502 by screws. An output shaft 504 is fixedly connected to the output end of motor 503. A first gear 505 is fixedly sleeved on the outer surface of output shaft 504. A second gear 506 is fixedly sleeved on the outer surface of seat shaft 501. The outer surfaces of the first gear 505 and the second gear 506 mesh. A blank butterfly valve workpiece 6 is attached between the outer surfaces of two clamping plates 309.

[0023] In this embodiment, when the butterfly valve multi-station processing system is in use, the blank butterfly valve workpiece 6 to be processed is transported to the material platform 203 of the multi-station processing component 2. Initial positioning is completed manually, so that the flange end face of the blank butterfly valve workpiece 6 faces the processing positioning component 3, completing the single workpiece loading preparation. The operator issues a clamping command on the control console. After clamping and positioning are completed, the control console starts the rotating component 5 to execute the indexing and transfer process: the support plate 507 at the center of the base plate 1 is fixed to the outer side of the sleeve plate 502. The outer wall of the sleeve plate 502 is locked to the motor 503 by screws. After the motor 503 is powered on, the output shaft 504 rotates at high speed, outputting... The first gear 505 fixed on shaft 504 rotates synchronously and meshes with the second gear 506 fixed at the lower end of the base shaft 501. Through the gear pair, the base shaft 501 is driven to rotate by speed reduction and torque increase. The upper end of the base shaft 501 is rigidly connected to the center of the turntable 301 of the machining positioning assembly 3, causing the turntable 301 to rotate smoothly in a circular motion. A cover plate 302 is fixed to the surface of the turntable 301, supporting the entire clamping structure and rotating synchronously with the blank butterfly valve workpiece 6. The equipment program controls the turntable 301 to rotate precisely at a fixed angle each time, sequentially indexing and feeding the blank butterfly valve workpiece 6 into the machining boxes 202 evenly arranged along the circumference of the base plate 1. In the first stage, the workpiece is transferred to the machining chamber 202 equipped with the turning unit 204. The turning unit 204 feeds its tool and performs rough turning and finish turning on the outer diameter of the valve body, the flange end face, and the stepped surface of the blank butterfly valve workpiece 6. The turntable 301 rotates again to index and send the turned workpiece through the brushes 208 mounted on the left and right sides of the machining chamber 202 to the machining chamber 202 equipped with the drilling and tapping unit 205. The drilling and tapping unit 205 first completes the drilling operation of the valve body flange mounting hole according to the preset coordinates, and then simultaneously completes the internal thread tapping after changing the tap. The workpiece is then transferred to the milling unit 206 station. Milling unit 206 mills the sealing surface and stem mounting groove of the butterfly valve to ensure that the flatness and roughness of the sealing surface meet the process standards. After all cutting is completed, the workpiece is transferred to the online precision detection feedback unit 207. The detection unit has built-in displacement sensors and vision inspection modules to automatically collect all key dimensional data such as valve body outer diameter, flange thickness, thread hole diameter, sealing surface flatness, and hole position. The system compares the data with the preset acceptable tolerance range in real time. When the detected dimension exceeds the tolerance, the equipment automatically marks the workpiece, and the turntable 301 can reverse index to send the workpiece back to the corresponding processing station for secondary processing.Once all dimensions pass inspection, the system determines that processing is complete and proceeds to the unloading process. After precision inspection, the turntable 301 rotates back to the loading / unloading station corresponding to the initial material table 203. The operator removes the finished butterfly valve from the material table 203. This device evenly arranges turning units 204, drilling and tapping units 205, milling units 206, and online precision detection feedback units 207 along the circumference of the base plate 1. Combined with independent loading / unloading tables 203, the motor 503 and gear pair drive the turntable 301 to precisely index and transfer the workpiece. A single machine can complete all cutting and inspection processes from butterfly valve blank to finished product, eliminating the need for multiple machine tools for segmented processing and manual transfer and disassembly, significantly shortening process flow time and improving the processing continuity and production capacity of butterfly valves.

[0024] like Figure 1-12 As shown, a hydraulic cylinder 323 is installed on the outer surface of the frame plate 322. One end of the hydraulic cylinder 323 is fixedly connected to one side of the outer surface of the connecting frame 321. Multiple connecting blocks 402 are evenly divided into two groups. A hollow cylinder 403 is fixedly connected between the outer surfaces of the two groups of connecting blocks 402. Two first ring plates 404 are fixedly connected to the outer surfaces of the two hollow cylinders 403. A first fixing plate 405 is evenly arranged in a circle on the outer surfaces of the four first ring plates 404. A first fixing shaft 406 is fixedly connected to the inner wall of the multiple first fixing plates 405. A driven rod 407 is movably sleeved on the outer surface of the multiple first fixing shafts 406. A second fixing shaft 408 is movably embedded near one edge of the inner wall of the multiple driven rods 407. The multiple second fixing shafts 408 are grouped in pairs. Inner support plates 409 are fixedly connected to the outer surfaces of the second fixed shafts 408. Silicone pads 410 are fixedly connected to one side of the outer surfaces of the inner support plates 409. Sliding shafts 411 are slidably connected to the inner walls of the two empty cylinders 403. Second ring plates 412 are fixedly sleeved on the outer surfaces of the two sliding shafts 411. Multiple second fixed plates 413 arranged evenly in a circle are fixedly connected to the outer surfaces of the two second ring plates 412. Third fixed shafts 414 are fixedly embedded in the inner walls of the multiple second fixed plates 413. Active rods 415 are movably sleeved on the outer surfaces of the multiple third fixed shafts 414. Fourth fixed shafts 416 are movably embedded in the inner walls of the multiple active rods 415 at one side edge. The outer surfaces of the multiple fourth fixed shafts 416 are fixedly connected to the inner walls of the multiple inner support plates 409 respectively.

[0025] In this embodiment, when the butterfly valve multi-station processing system is in use, the blank butterfly valve workpiece 6 to be processed is transported to the material platform 203 of the multi-station processing component 2. The operator issues a clamping command on the control console, and the hydraulic cylinder 323 installed on the frame plate 322 drives the connecting frame 321 to move. The connecting frame 321 synchronously pulls the left and right sets of first movable plates 310. The first movable plate 310 is hinged to the movable rod 312 through the internally embedded first rotating shaft 311. The inner wall of the movable rod 312 is rotatably connected to the second rotating shaft 315 near the other edge, forming a parallel four-bar linkage transmission structure, which drives the two connecting shafts 307 to slide vertically inward along the first slide rail 304 fixed to the first connecting rod 303 on both sides of the cover plate 302. The clamping plate 308, fixed at the front end of the connecting shaft 307, moves synchronously towards the center. The clamping plate 309, attached to the inner side of the clamping plate 308, fits against both sides of the outer circle of the blank butterfly valve workpiece 6, achieving flexible clamping of the workpiece on the outside. After clamping and positioning, the control console starts the rotating component 5 to execute the indexing and transfer process, sequentially indexing and sending the blank butterfly valve workpiece 6 into the internal workstations of each processing box 202 evenly arranged along the circumference of the base plate 1. The workpiece is first transferred to the processing box 202 equipped with the turning processing unit 204. The turning processing unit 204 feeds the tool and performs rough turning and finish turning on the outer circle of the valve body, flange end face, and stepped surface of the blank butterfly valve workpiece 6. When it is necessary to process the position where the clamping plate 309 of the blank butterfly valve workpiece 6 is in contact, the workpiece is further processed. During operation, the hydraulic cylinder 323 is activated to move the connecting frame 321, causing the two connecting shafts 307 to slide vertically inward along the first slide rail 304 fixed to the first connecting rod 303 on both sides of the cover plate 302. The clamping plate 308 fixed to the front end of the connecting shaft 307 moves synchronously away from the blank butterfly valve workpiece 6. At this time, the slide cylinder 313, which is installed inside the second slide rail 306, feeds synchronously inward along the second slide rail 306 fixed to the second connecting rod 305. The second movable plate 314 fixed to the outside of the slide cylinder 313 is hinged to the other end of the movable rod 312 through the second rotating shaft 315. Multiple rollers 317 are installed on the shaft 316 inside the slide cylinder 313. The rollers 317 are fitted with annular tracks 318. One side of track 318 is fixed to the inner wall of the second slide rail 306 via the first connecting plate 319, and the other side is rigidly connected to the moving cylinder 417 of the driven clamping assembly 4 via the second connecting plate 320. Track 318 synchronously pulls the moving cylinder 417 forward as the slide cylinder 313 feeds, pulling the sliding shaft 411 to slide forward inside the two sets of empty cylinders 403. Multiple first fixing plates 405 are fixed around the outside of the empty cylinder 403 via the first ring plate 404. The first fixing plates 405 are hinged to the driven rod 407 via the first fixing shaft 406. The outer wall of the sliding shaft 411 is fixed to the second ring plate 412. Multiple second fixing plates 413 are arranged around the second ring plate 412. The second fixing plates 413 are hinged to the driving rod 415 via the third fixing shaft 414.The sliding shaft 411 moves forward, causing the active rod 415 to expand outward around the third fixed shaft 414. The end of the active rod 415 is connected to the inner support plate 409 through the fourth fixed shaft 416. A silicone pad 410 is attached to the outside of the inner support plate 409. Multiple sets of inner support plates 409 expand outward simultaneously, tightening the inner wall from inside the valve body of the blank butterfly valve workpiece 6, forming an inner support limit of the internal silicone pad 410. This device is equipped with two sets of flexible positioning mechanisms: an outer clamping plate 308 for external clamping and an inner multi-lobed inner support plate 409 for internal support. Automatic switching is achieved through hydraulic linkage with the crawler 318. In conventional processing, the clamping plate 308 with clamping plate 309 clamps the butterfly valve workpiece from the outside. When the clamping obstruction area needs to be cut, the equipment automatically releases the outer clamping and simultaneously extends the inner support assembly. Multiple sets of inner support plates 409 with silicone pad 410 tighten and position from inside the valve body, thereby effectively improving the efficiency of automated continuous processing on the production line.

[0026] like Figure 1-12 As shown, the inner walls of the four second movable plates 314 are all fixedly embedded with second rotating shafts 315. The inner walls of the eight movable rods 312 are rotatably connected to the outer surfaces of the four second rotating shafts 315 at both ends near one side edge. The inner walls of the two slide cylinders 313 are all fixedly embedded with two opposing embedded shafts 316 near both side edges. The outer surfaces of the eight embedded shafts 316 are movably fitted with rollers 317. The eight rollers 317 are grouped in pairs. Tracks 318 are movably fitted between the outer surfaces of the multiple groups of rollers 317. The four tracks 31... The outer surface of track 8 is fixedly connected to four of the rollers 317 with first connecting plates 319. Each pair of the four first connecting plates 319 forms a group. The outer surfaces of the two groups of first connecting plates 319 are fixedly connected to the inner walls of the two second slide rails 306 respectively. The outer surfaces of the four tracks 318 are fixedly connected to the other four rollers 317 with second connecting plates 320. A connecting frame 321 is fixedly connected between the outer surfaces of the two first movable plates 310. A frame plate 322 is fixedly connected to one side of the outer surface of the cover plate 302.

[0027] In this embodiment, when the butterfly valve multi-station machining system is in use, the operator issues a clamping command on the control panel. The hydraulic cylinder 323 installed on the frame plate 322 drives the connecting frame 321 to move. The connecting frame 321 synchronously pulls the left and right sets of first movable plates 310. The first movable plate 310 is hinged to the movable rod 312 through the internally embedded first rotating shaft 311. The inner wall of the movable rod 312 is rotatably connected to the second rotating shaft 315 near the other edge, forming a parallel four-bar linkage transmission structure. This drives the two connecting shafts 307 to slide vertically inward along the first slide rail 304 fixed to the first connecting rods 303 on both sides of the cover plate 302. This achieves flexible clamping of the workpiece on the outside. When it is necessary to process the position where the clamping plate 309 of the blank butterfly valve workpiece 6 is in contact, the hydraulic cylinder 323 is activated to drive the connecting frame. 321 moves, and the connecting frame 321 simultaneously pulls the left and right sets of first movable plates 310. The first movable plate 310 is hinged to the movable rod 312 through the first rotating shaft 311 embedded inside. The inner wall of the movable rod 312 is rotatably connected to the second rotating shaft 315 near the other edge, forming a parallel four-bar linkage transmission structure. This drives the two connecting shafts 307 to slide vertically inward along the first slide rail 304 fixed to the first connecting rod 303 on both sides of the cover plate 302. This forms the inner support limit of the internal silicone pad 410, clamping and positioning. The entire clamping mechanism of this device relies on the parallel four-bar linkage and the track 318 for synchronous transmission. It only needs a single hydraulic cylinder 323 as a power source to synchronously drive the two sets of mechanisms, namely the outer clamping and the inner support. The synchronicity of the actions of each clamping component is high, which effectively improves the positioning stability of this device.

[0028] The usage and working principle of this device: When the butterfly valve multi-station processing system is in use, the blank butterfly valve workpiece 6 to be processed is transported to the material platform 203 of the multi-station processing component 2. Initial positioning is completed manually, so that the flange end face of the blank butterfly valve workpiece 6 faces the processing positioning component 3, completing the single workpiece loading preparation. The operator issues a clamping command on the control panel, and the hydraulic cylinder 323 installed on the frame plate 322 drives the connecting frame 321 to move. The connecting frame 321 synchronously pulls the left and right sets of first movable plates 310. The first movable plate 310 is hinged to the movable rod 312 through the internally embedded first rotating shaft 311. The inner wall of the movable rod 312 near the other edge is rotatably connected to the second rotating shaft 315, forming a parallel four-bar linkage transmission structure. The two connecting shafts 307 slide vertically inward along the first slide rails 304 fixed to the first connecting rods 303 on both sides of the cover plate 302. The clamping plate 308 fixed at the front end of the connecting shaft 307 moves towards the center in sync. The clamping plate 309 attached to the inner side of the clamping plate 308 fits against the outer sides of the blank butterfly valve workpiece 6, realizing flexible clamping of the outer side of the workpiece. While the connecting shaft 307 slides, it will drive the slide cylinder 313 and the driven clamping assembly 4 to move away from the blank butterfly valve workpiece 6 through the movable rod 312. After the clamping and positioning is completed, the control console starts the rotating assembly 5 to perform the indexing and transfer process: the support plate 507 at the center of the base plate 1 is fixed to the outer side of the sleeve plate 502. The outer wall of the sleeve plate 502 is locked with the motor 503 by screws. After the motor 503 is powered on, The output shaft 504 rotates at high speed, and the first gear 505 fixed on the output shaft 504 rotates synchronously, meshing with the second gear 506 fixed at the lower end of the seat shaft 501. The gear pair reduces speed and increases torque, driving the seat shaft 501 to rotate. The upper end of the seat shaft 501 is rigidly connected to the center of the turntable 301 of the machining positioning assembly 3, and the turntable 301 rotates smoothly in a circular motion. A cover plate 302 is fixed on the surface of the turntable 301. The cover plate 302 supports the entire clamping structure and rotates synchronously with the blank butterfly valve workpiece 6. The equipment program controls the turntable 301 to rotate precisely at a fixed angle each time, and sequentially indexes and sends the blank butterfly valve workpiece 6 into the internal workstations of each machining box 202 evenly arranged along the circumference of the base plate 1. The workpiece is first transferred to the machining box 202 equipped with the turning machining unit 204. Inside 2, the turning unit 204 feeds the tool to perform rough and finish turning on the outer diameter of the valve body, the flange end face, and the stepped surface of the blank butterfly valve workpiece 6. When it is necessary to process the position where the clamping plate 309 of the blank butterfly valve workpiece 6 is in contact, the hydraulic cylinder 323 is activated to drive the connecting frame 321 to move. The connecting frame 321 pulls the two sets of first movable plates 310 on the left and right at the same time. The first movable plate 310 is hinged to the movable rod 312 through the first rotating shaft 311 embedded inside. The inner wall of the movable rod 312 is rotatably connected to the second rotating shaft 315 near the other edge, forming a parallel four-bar linkage transmission structure, which drives the two connecting shafts 307 to slide vertically inward along the first slide rail 304 fixed by the first connecting rod 303 on both sides of the cover plate 302.The clamping plate 308 fixed at the front end of the connecting shaft 307 moves synchronously away from the blank butterfly valve workpiece 6. At this time, the slide cylinder 313, which is installed inside the second slide rail 306, feeds inward synchronously along the second slide rail 306 fixed by the second connecting rod 305. The second movable plate 314 fixed on the outside of the slide cylinder 313 is hinged to the other end of the movable rod 312 through the second rotating shaft 315. Multiple rollers 317 are installed on the shaft 316 inside the slide cylinder 313. A ring track 318 is sleeved on the outside of the rollers 317. One side of the track 318 is fixed to the inner wall of the second slide rail 306 through the first connecting plate 319, and the other side is connected to the driven clamping assembly 4 through the second connecting plate 320. The cylinder 417 is rigidly connected; the track 318, along with the feed of the sliding cylinder 313, synchronously pulls the moving cylinder 417 forward, causing the sliding shaft 411 to slide forward inside the two sets of empty cylinders 403. Multiple first fixing plates 405 are circumferentially fixed to the outside of the empty cylinders 403 via a first ring plate 404. Each first fixing plate 405 is hinged to a driven rod 407 via a first fixing shaft 406. A second ring plate 412 is fixed to the outer wall of the sliding shaft 411. Multiple second fixing plates 413 are circumferentially arranged on the second ring plate 412. Each second fixing plate 413 is hinged to a driving rod 415 via a third fixing shaft 414. The forward movement of the sliding shaft 411 causes the driving rod 415 to expand outward around the third fixing shaft 414, thus... The end of rod 415 is connected to inner support plate 409 via fourth fixed shaft 416. Silicone pad 410 is attached to the outside of inner support plate 409. Multiple sets of inner support plates 409 expand outwards simultaneously, supporting the inner wall from inside the valve body of the blank butterfly valve workpiece 6, forming an inner support limit of the internal silicone pad 410. After clamping and positioning, further processing is carried out. Turntable 301 rotates again to index and send the machined workpiece through brushes 208 mounted on the left and right sides of machining box 202 to machining box 202 equipped with drilling and tapping unit 205. Drilling and tapping unit 205 first completes the drilling operation of valve body flange mounting hole according to preset coordinates, and then simultaneously completes internal thread tapping after changing tap. The workpiece flows The workpiece is then transferred to milling unit 206, where it is milled to shape the butterfly valve's sealing surface and stem mounting groove, ensuring that the flatness and roughness of the sealing surface meet the process standards. After all cutting operations are completed, the workpiece is transferred to precision online detection and feedback unit 207. This detection unit has built-in displacement sensors and a vision inspection module, which automatically collects all key dimensional data, including the valve body outer diameter, flange thickness, thread hole diameter, sealing surface flatness, and hole position accuracy. The system compares the data with preset acceptable tolerance ranges in real time. If the detected dimensions exceed the tolerance, the equipment automatically marks the workpiece, and the turntable 301 can reverse index, sending the workpiece back to the corresponding processing station for secondary processing.Once all dimensions pass inspection, the system determines that processing is complete and proceeds to the unloading process. After precision inspection is passed, the turntable 301 rotates back to the loading / unloading position corresponding to the initial material table 203. The operator removes the finished butterfly valve from the material table 203. The turning unit 304, drilling and tapping unit 205, milling unit 206, and online precision detection feedback unit 207 in this device can perform multi-directional processing on the blank butterfly valve workpiece 6.
