Technical Field
[0001] This utility model relates to the field of guide vane production technology, specifically a grinding device for guide vane production. Background Technology
[0002] In the field of guide vane manufacturing, the grinding process plays a crucial role in product quality and production efficiency. However, existing guide vane grinding equipment has many problems in practical applications. In terms of clamping, traditional clamping methods often require the design of special fixtures for guide vanes of specific sizes and thicknesses. When grinding guide vanes of different specifications, it is necessary to frequently change the fixtures. This not only increases production costs, as customizing and changing fixtures requires a large investment, but also makes the operation complex and requires high technical skills from workers, resulting in high operational difficulty. At the same time, the clamping effect of these fixtures is not ideal. During the grinding process, the guide vane is prone to displacement and shaking, making it difficult to guarantee grinding accuracy. This leads to inconsistent product quality and seriously affects the performance and service life of the guide vanes.
[0003] Regarding rotation functionality, most existing grinding equipment can only achieve rotation in one direction for the guide vane body, or it lacks rotation functionality altogether. If rotation in only one direction is possible, the grinding components cannot work evenly on the guide vane body surface, easily leading to over- or under-grinding in certain areas. This results in inconsistent surface roughness of the guide vane body, affecting the product's appearance and hydrodynamic performance. On the other hand, the lack of rotation functionality means that the position of the guide vane body needs to be frequently adjusted manually when grinding different sides of the guide vane body. This not only increases labor intensity but also results in larger human operation errors, further reducing grinding efficiency and quality, making it difficult to meet the needs of large-scale, high-precision production. These problems seriously restrict the development of the guide vane body manufacturing industry. Therefore, there is an urgent need to improve the grinding equipment for guide vane body production to solve the above problems. Utility Model Content

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1:
[0025] Based on existing technology, traditional clamping methods often involve designing specialized fixtures for guide vane bodies of specific sizes and thicknesses. When grinding guide vane bodies of different specifications, frequent fixture changes are necessary. This not only increases production costs—as customizing and replacing fixtures requires significant investment—but also involves complex operations that demand high levels of skill from workers, leading to operational difficulties. Furthermore, the clamping effect of these fixtures is not ideal; during grinding, the guide vane body is prone to displacement and wobbling, making it difficult to guarantee grinding accuracy and resulting in inconsistent product quality, severely impacting the performance and lifespan of the guide vane body. Therefore, this device features a more versatile clamping mechanism. Please refer to [link / reference]. Figures 1-6This utility model provides a technical solution: a grinding equipment for guide vane production, including a worktable 1, a support leg 2 fixedly installed at the bottom of the worktable 1, a protective cover 3 fixedly installed above the worktable 1, a protective door 5 movably installed on the front of the protective cover 3 via a hinge 4, an observation window 6 provided on the protective door 5, a support frame 7 and a grinding component 8 provided inside the protective cover 3, and a clamping component 9 provided on the worktable 1; the grinding equipment for guide vane production includes a clamping mechanism, a grinding mechanism and a rotating mechanism, the clamping mechanism includes a worktable 1, a mounting frame 301 fixedly installed on the worktable 1, a rotating shaft 302 movably installed in the mounting frame 301, a clamping body 303 movably installed inside the mounting frame 301, and the rotating shaft 302 passing through the mounting frame 301 and fixedly installed on the side of the clamping body 303.
[0026] A motor 304 is fixedly installed at the bottom center of the fixture body 303. The output shaft of the motor 304 is fixedly installed on the drive shaft 305. A transmission groove is provided inside the fixture body 303. A drive wheel 306 is fixedly installed on the drive shaft 305. A transmission shaft 308 is movably installed inside the fixture body 303. A bevel gear 307 and a bevel gear 309 are fixedly installed at both ends of the transmission shaft 308, respectively. The bevel gear 307 meshes with the drive wheel 306. A screw 311 is movably installed inside the fixture body 303. A bevel gear 310 is fixedly installed at the lower end of the screw 311. The bevel gear 309 meshes with the bevel gear 310.
[0027] The clamp body 303 has sliding grooves 312 on both sides, and a top pressure plate 313 is movably installed in the sliding grooves 312. The two ends of the top pressure plate 313 are movably installed on the screw rod 311 by threads. The threads of the two screw rods 311 on both sides inside the clamp body 303 are opposite.
[0028] The bottom of the top pressure plate 313 is provided with a limiting tooth 316. A limiting rod 318 is movably installed in the middle of the top pressure plate 313. A limiting plate 319 is fixedly installed on the top of the limiting rod 318. A limiting tooth 317 that meshes with the limiting tooth 316 is provided on the limiting rod 318. A top pressure plate 320 is provided below the limiting tooth 317. A top pressure head 321 is provided below the top pressure plate 320. A spring 322 is movably installed between the top pressure plate 320 and the top pressure plate 313.
[0029] The grinding mechanism includes a protective cover 3 and a support frame 7. A water tank 201 is fixedly installed on the top of the protective cover 3. A water pump 202 is located next to the water tank 201. The water tank 201 and the water pump 202 are fixedly connected by a connecting pipe 203. A water spray pipe 204 is fixedly installed at the outlet of the water pump 202. The water spray pipe 204 passes through the protective cover 3 and a nozzle 208 is fixedly installed at its end. A dust collection box 205 is located behind the water pump 202. An air pump and a dust collection device are installed inside the dust collection box 205. A dust collection hood 206 is located next to the dust collection box 205. The dust collection box 205 and the dust collection hood 206 are fixedly connected by a dust collection pipe 207. The dust collection hood 206 is fixedly installed on the top of the protective cover 3. A grinding component 8 is fixedly installed on the support frame 7.
[0030] Before starting the equipment, open the protective door 5 and place the guide vane body 315 to be ground on the turntable 314, aligning the center pressure hole 323 of the guide vane body 315 with the pressure head 321. Close the protective door 5 and prepare to start the grinding work. Start the motor 304. The output shaft of the motor 304 drives the drive shaft 305 to rotate, and the drive wheel 306 on the drive shaft 305 rotates accordingly. The drive wheel 306 meshes with the bevel gear 307 at one end of the transmission shaft 308, driving the transmission shaft 308 to rotate. The bevel gear 309 at the other end of the transmission shaft 308 rotates and meshes with the bevel gear 310, thereby causing the screw 311 to rotate. Due to the clamping body 303 The screws 311 on both sides have opposite thread directions, and the top pressure plate 313 is threaded onto the screws 311 at both ends. When the screws 311 rotate, the top pressure plates 313 on both sides move up and down in the slide groove 312. When the top pressure plate 313 moves downward, the top pressure head 321 gradually approaches and inserts into the top pressure hole 323 of the guide vane body 315. The top pressure plate 320 fits tightly against the guide vane body 315 under the action of the spring 322 until the first limiting tooth 316 meshes with the second limiting tooth 317, which plays a locking role. By controlling the speed and direction of rotation of the motor 304, the clamping force of the top pressure plate 313 can be adjusted to ensure that the guide vane body 315 is stable and does not shift during the grinding process.
[0031] When the water pump 202 is started, the water in the water tank 201 is pumped to the spray pipe 204 through the connecting pipe 203 and sprayed out through the nozzle 208 to cool and reduce dust in the grinding area. At the same time, the air pump in the dust collection box 205 is started, and the dust collection hood 206 collects the dust generated during grinding. The dust is then sucked into the dust collection device in the dust collection box 205 through the dust collection pipe 207 to keep the working environment clean. The grinding component 8 on the support frame 7 starts to work under the power drive to grind the guide vane body 315.
[0032] Example 2:
[0033] Based on Example 1, most existing grinding equipment can only achieve unidirectional rotation of the guide vane body, or lacks rotation functionality altogether. Unidirectional rotation prevents the grinding components from evenly applying force to the guide vane surface, easily leading to over- or under-grinding in certain areas. This results in inconsistent surface roughness, affecting the product's appearance and hydrodynamic performance. The lack of rotation functionality means frequent manual adjustments to the guide vane's position when grinding different sides, increasing labor intensity and introducing significant human error, further reducing grinding efficiency and quality. This makes it difficult to meet the demands of large-scale, high-precision production. Therefore, this device features a special rotation mechanism. Please refer to [link / reference]. Figures 3-7 This utility model provides a technical solution: a grinding device for producing guide vane bodies, the rotating mechanism including a clamping body 303, a worktable 1, and a rotating shaft 302, a turntable 314 is movably installed in the middle position of the clamping body 303, the bottom of the turntable 314 is fixedly connected to the top of the drive shaft 305, a guide vane body 315 is placed on the turntable 314, and the center of the guide vane body 315 has a top pressure hole 323 that cooperates with the top pressure head 321.
[0034] A second motor 401 is fixedly installed on the workbench 1. The output shaft of the second motor 401 is fixedly installed on the second drive shaft 402. A drive gear 403 is fixedly installed on the second drive shaft 402. A driven gear 405 is fixedly installed on the rotating shaft 302. The drive gear 403 meshes with the driven gear 405. The rotating shaft 302 passes through the bearing 406 and is fixedly installed on the side of the fixture 303.
[0035] When motor 2 401 is started, the output shaft of motor 2 401 drives drive shaft 2 402 to rotate. Drive gear 403 on drive shaft 2 402 rotates accordingly. Drive gear 403 meshes with driven gear 405 on rotating shaft 302, causing rotating shaft 302 to rotate. This, in turn, drives clamp body 303 to rotate vertically around rotating shaft 302, realizing vertical rotation of guide vane body 315. This ensures that grinding assembly 8 can evenly act on the surface of guide vane body 315. At the same time, since the bottom of turntable 314 is fixedly connected to the top of drive shaft 1 305, when motor 1 304 drives drive shaft 1 305 to rotate, turntable 314 will also rotate accordingly, realizing horizontal rotation of guide vane body 315. This facilitates all-round grinding of different sides of guide vane body 315.
