Description

Technical Field

[0001] This invention relates to the field of yaw gear ring processing technology, and in particular to a grinding device for processing wind turbine yaw gear rings and its usage method. Background Technology

[0002] The yaw gear ring is the core transmission component in a wind turbine to achieve "yaw to wind". It is responsible for driving the nacelle to rotate to track the wind direction and bearing the entire weight of the nacelle and the wind load. During the processing of the wind turbine yaw gear ring, it is necessary to grind it to ensure its own precision and facilitate its subsequent deployment.

[0003] Based on an understanding of the current applications of grinding in the machining of yaw gear rings for wind turbines, the following shortcomings exist: 1. The lack of a precise center positioning and position adjustment mechanism makes it impossible to quickly determine the center of the gear ring, which can easily lead to grinding position deviation during the grinding process. This makes it difficult to guarantee the grinding accuracy of the outer circumference and specific parts of the gear ring, affecting the stability of subsequent assembly and use.

[0004] 2. For wind turbine yaw gear rings of different sizes, the existing fixing structure cannot be flexibly adjusted. Special clamps or accessories must be replaced to complete the fixing, which is cumbersome and costly to adapt, and cannot meet the diverse processing needs.

[0005] 3. The angle adjustment of the grinding components lacks visualization and precise control, making it difficult to adapt to the grinding areas with different tilt angles of the gear ring; at the same time, the movement adjustment range of the gear ring is limited, making it impossible to achieve comprehensive and uniform peripheral grinding, and easily leading to problems such as incomplete or excessive grinding in certain areas.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a grinding device and its usage method for processing wind turbine yaw gear rings, in order to achieve a more practical purpose. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a grinding device and its method for processing wind turbine yaw gear rings. This addresses the shortcomings of existing devices, which lack precise center positioning and adjustment mechanisms, making it difficult to quickly determine the center of the gear ring. This leads to frequent grinding position deviations during the grinding process, making it difficult to guarantee grinding accuracy on the outer circumference and specific areas of the gear ring, affecting subsequent assembly and usage stability. Furthermore, for wind turbine yaw gear rings of different sizes, the existing device's fixing structure cannot be flexibly adjusted, requiring the replacement of special clamps or accessories for fixation, resulting in cumbersome operation and high adaptation costs, failing to meet diverse processing needs. Additionally, the angle adjustment of the grinding components lacks visualization and precise control, making it difficult to adapt to grinding areas with different tilt angles on the gear ring. Simultaneously, the limited range of gear ring movement adjustment prevents comprehensive and uniform outer circumference grinding, easily leading to incomplete or excessive grinding in certain areas.

[0008] This invention provides a grinding device for processing wind turbine yaw gear rings, specifically comprising: an assembly frame; a grinding frame fixedly installed at the top rear end of the assembly frame, an adjusting frame fixedly installed at the front middle of the grinding frame, a motor E fixedly installed at the top middle of the adjusting frame, the shaft of motor E being threaded and located inside the adjusting frame, a lifting block slidably connected to the inside of the adjusting frame, and a threaded hole opened at the top middle of the lifting block, the shaft of motor E being located inside the threaded hole of the lifting block, a laser positioner provided at the middle of the lifting block, the front end of the lifting block being fixedly connected to the rear middle of the angle frame, a motor F fixedly installed at the left side of the angle frame, the shaft of motor F being fixedly connected to the left side of the angle seat, semi-circular angle scale plates provided on both sides of the angle seat, and a grinding machine provided at the front middle of the angle seat.

[0009] Furthermore, a progress frame is fixedly installed at the top center of the assembly frame, and a motor A is provided at the rear center of the progress frame. The shaft of motor A is threaded and located inside the progress frame. A progress block is slidably connected inside the progress frame, and a threaded hole is provided at the front center of the progress block. The shaft of motor A is located inside the threaded hole of the progress block.

[0010] Furthermore, a motor B is fixedly installed at the top center of the advancing block, and the shaft of motor B is fixedly connected to the bottom center of the turntable. When the rear end of the advancing block is in contact with the rear end of the advancing block, the turntable is located directly below the laser positioner.

[0011] Furthermore, a lifting frame is fixedly installed at the front of the inside of the assembly frame, and a motor C is fixedly installed at the lower inside of the lifting frame. The shaft of the motor C is threaded and located inside the lifting frame. The upper inside of the lifting frame is slidably connected to the front of the lifting plate. A threaded hole is provided at the front center of the lifting plate, and the shaft of the motor C is located inside the threaded hole of the lifting plate.

[0012] Furthermore, the top rear position of the lifting plate is fixedly connected to the bottom position of the spacing limiting frame. A motor D is fixedly installed on the left side of the spacing limiting frame. The rotating shaft of the motor D is provided with a reverse thread, and the reverse thread of the motor D is located on the left and right sides inside the spacing limiting frame. The left and right sides inside the spacing limiting frame are slidably connected to the bottom position of a T-shaped support. Each T-shaped support has a threaded hole on its lower side. The threaded holes of the two T-shaped supports are designed in opposite directions, and the two ends of the rotating shaft of the motor D are located in the threaded holes of a T-shaped support.

[0013] Furthermore, a locking chuck frame is fixedly installed at the top center of the turntable. The top of the locking chuck frame has three sliding grooves, and a motor G is fixedly installed at the front center of the locking chuck frame. A bevel gear is fixedly installed on the shaft of the motor G, and the bevel gear is located at the front of the inside of the locking chuck frame.

[0014] Furthermore, a chuck gear ring is rotatably connected to the inner middle position of the locking chuck frame. A bevel gear meshes with the bottom front position of the chuck gear ring, and a helical groove is provided at the top position of the chuck gear ring. A chuck claw is slidably connected in each of the three sliding grooves at the top of the locking chuck frame. The bottom position of each chuck claw meshes with the helical groove at the top of the chuck gear ring. An arc-shaped plate is fixedly installed at the top position of each chuck claw. The three arc-shaped plates are arranged in a ring above the top of the locking chuck frame. A gear ring component is placed above the locking chuck frame, and the three arc-shaped plates are located inside the gear ring component.

[0015] This invention also discloses a method for using a grinding device for machining wind turbine yaw gear rings, comprising the following steps: 1) Place the gear ring at the top of the locking chuck frame, with the three arc plates inside the gear ring. Then start the motor G. The shaft of the motor G drives the bevel gear to rotate. The bevel gear meshes with the front bottom of the chuck gear ring, driving the chuck gear ring to rotate in the middle position inside the locking chuck frame. The spiral groove at the top of the chuck gear ring meshes with the bottom of the three chuck claws. As the chuck gear ring rotates, the three chuck claws move away from the center synchronously along the three sliding grooves at the top of the locking chuck frame until the outer side of the three arc plates fits against the inner side of the gear ring without any looseness. Then turn off the motor G. At this time, the gear ring will be centered and restricted in the middle position at the top of the locking chuck frame, and can be fixed according to different gear ring sizes. 2) Start motor A. The threaded shaft of motor A rotates, driving the advance block to slide backward along the inside of the advance frame. The advance block synchronously drives the top motor B, turntable and locking chuck frame to move towards the grinding area. 3) When the rear end of the advancing block is in contact with the rear end of the advancing frame, turn off motor A. At this time, the turntable is exactly below the laser positioner. At this time, it can be determined that the center position of the gear ring is directly below the laser positioner. Then, according to the radius of the gear ring, start the motor A shaft to reverse. The advancing block slides forward inside the advancing frame at a distance that matches the radius of the gear ring. 4) Start motor E. Motor E drives the lifting block to slide up and down along the inside of the adjustment frame. The lifting block synchronously drives the angle frame, angle seat and grinding machine to rise and fall until the grinding head of the grinding machine is in contact with the surface of the gear ring to be ground. Then start the grinding machine to grind the gear ring. 5) After starting motor B, the shaft of motor B drives the turntable to rotate slowly and evenly to avoid uneven grinding caused by excessive speed. The turntable drives the gear ring to rotate synchronously, so that the grinder can grind the outer circumference of the gear ring. 6) Start motor F. The shaft of motor F drives the angle seat to rotate around its own axis. By observing the semi-circular angle scale plates on the left and right sides of the angle seat, adjust the grinding machine at the front end of the angle seat to the tilt grinding angle that matches the part of the gear ring to be ground.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. With the help of the laser positioner and the advancing frame, when the advancing block is in contact with the rear end of the advancing frame, the center of the gear ring can be quickly determined to be directly below the laser positioner. Combined with the precise drive of motor A, the front and rear positions can be adjusted according to the radius of the gear ring, with small positioning error. Motor E drives the lifting block to move the grinding machine up and down, which can accurately control the fit between the grinding head and the surface of the gear ring to be ground, further ensuring the grinding accuracy.

[0017] 2. The locking chuck frame is driven by a bevel gear via motor G, which rotates the chuck gear ring. This causes the three chuck claws to move synchronously away from or towards the center along the slide groove. Combined with the top arc plate, it can flexibly adapt to gear ring parts of different intermediate sizes without the need to change the fixture, thus reducing adaptation costs.

[0018] 3. The angle seat has semi-circular angle scale plates on both sides. Motor F can drive the angle seat to rotate, realizing the visual and precise adjustment of the grinder's tilt angle, perfectly adapting to the parts to be ground at different tilt angles of the gear ring, and improving the grinding quality of complex parts; Motor B drives the turntable to rotate slowly and evenly, ensuring the stable rotation of the gear ring. Combined with the fixed position of the grinder, it can achieve 360° full grinding of the outer circumference of the gear ring, avoiding local missed grinding; At the same time, Motor A can finely adjust the front and rear position of the gear ring to further expand the grinding coverage area.

[0019] 4. After grinding, motor A drives the advancing block to move the gear ring to the top of the lifting frame. Motor C drives the lifting plate to rise, so that the T-shaped support lifts the gear ring away from the arc plate. No manual intervention is required, and the unloading is completed quickly, shortening the process time. Motor D in the lifting frame drives the two T-shaped supports to slide in opposite directions through the reverse thread. The lifting distance can be adjusted according to the size of the gear ring to meet the unloading requirements of gear rings of different diameters. Attached Figure Description

The threaded holes of the two T-shaped supports 205 are designed in opposite directions, and the two ends of the shaft of the motor D204 are respectively located in the threaded holes of a T-shaped support 205.

[0031] Among them, a locking chuck frame 4 is fixedly installed at the top center of the turntable 105. The top of the locking chuck frame 4 has three sliding grooves, and a motor G401 is fixedly installed at the front center of the locking chuck frame 4. A bevel gear 402 is fixedly installed on the shaft of the motor G401. The bevel gear 402 is located at the front of the inside of the locking chuck frame 4.

[0032] The locking chuck frame 4 has a chuck gear ring 403 rotatably connected to its inner center position. The bottom front position of the chuck gear ring 403 meshes with a bevel gear 402. The top position of the chuck gear ring 403 is provided with a spiral groove. The top three grooves of the locking chuck frame 4 are each slidably connected to a chuck claw 404. The bottom position of each chuck claw 404 meshes with the spiral groove at the top of the chuck gear ring 403. The top position of each chuck claw 404 is fixedly installed with an arc plate 405. The three arc plates 405 are arranged in a ring above the top of the locking chuck frame 4. A gear ring 5 is placed above the locking chuck frame 4. The three arc plates 405 are located inside the gear ring 5.

[0033] In use: First, place the gear ring 5 at the top of the locking chuck frame 4, with the three arc plates 405 inside the gear ring 5. Next, start the motor G401. The shaft of the motor G401 drives the bevel gear 402 to rotate. The bevel gear 402 meshes with the bottom front of the chuck ring 403, driving the chuck ring 403 to rotate in the middle position inside the locking chuck frame 4. The spiral groove at the top of the chuck ring 403 meshes with the bottom of the three chuck claws 404. As the chuck ring 403 rotates, the three chuck claws 404 move away from the center synchronously along the three sliding grooves at the top of the locking chuck frame 4 until the outer side of the three arc plates 405 fits against the inner side of the gear ring 5 without any looseness. Then, turn off the motor G401. At this time, the gear ring 5 will be centered and restricted in the middle position at the top of the locking chuck frame 4, and can be fixed according to different gear ring 5 middle sizes. Start motor A102, the threaded shaft of motor A102 rotates, driving the advance block 103 to slide backward along the inside of the advance frame 101. The advance block 103 synchronously drives the top motor B104, turntable 105 and locking chuck frame 4 to move towards the grinding area. When the rear end of the advancing block 103 is in contact with the rear end of the advancing frame 101, the motor A102 is turned off. At this time, the turntable 105 is exactly below the laser positioner 304. At this time, it can be determined that the center of the gear ring 5 is located directly below the laser positioner 304. Then, the motor A102 shaft is started to reverse according to the radius of the gear ring 5. The advancing block 103 slides forward inside the advancing frame 101 at a distance that matches the radius of the gear ring 5. Start motor E302. Motor E302 drives lifting block 303 to slide up and down along the inside of adjustment frame 301. Lifting block 303 synchronously drives angle frame 305, angle seat 307 and grinder 308 to rise and fall until the grinding head of grinder 308 is in contact with the surface of gear ring 5 to be ground. Then start grinder 308 to grind gear ring 5. After starting the motor B104, the rotating shaft of the motor B104 drives the turntable 105 to rotate slowly and uniformly to avoid uneven grinding caused by excessive speed. The turntable 105 drives the gear ring 5 to rotate synchronously, so that the grinder 308 can grind the outer circumference of the gear ring 5. Start the motor F306. The shaft of the motor F306 drives the angle seat 307 to rotate around its own axis. By observing the semi-circular angle scale plates on the left and right sides of the angle seat 307, adjust the grinder 308 at the front end of the angle seat 307 to a tilt grinding angle that matches the part of the gear ring 5 to be ground.

[0034] During the grinding process, if it is necessary to adjust the grinding position, the front and rear grinding positions of the gear ring 5 can be adjusted by the fine-tuning motor A102, and the height grinding position of the gear ring 5 can be adjusted when the motor E302 is working.

[0035] After grinding is completed, start motor A102 in reverse. The threaded shaft of motor A102 rotates, driving the advance block 103 to slide forward along the inside of the advance frame 101 until the locking chuck frame 4 is located directly above the lifting frame 2. Combined with the size of the gear ring 5, start motor D204. The reverse thread of the shaft of motor D204 can drive the two T-shaped supports 205 to slide in opposite directions inside the spacing limiting frame 203, so that the two spacing limiting frames 203 are symmetrically located on the left and right sides of the bottom of the gear ring 5. Then start motor C201 to drive the lifting plate 202 to slide upward along the inside of the lifting frame 2, causing the top of the T-shaped support 205 to contact the bottom of the gear ring 5 until the T-shaped support 205 lifts the gear ring 5 away from the outer position of the three arc plates 405, which facilitates the unloading of the gear ring 5.

The bevel gear (402) meshes with the bottom front of the chuck ring (403), driving the chuck ring (403) to rotate in the middle position inside the locking chuck frame (4). The spiral groove at the top of the chuck ring (403) engages with the three chucks. The bottom of the claw (404) engages. As the chuck tooth ring (403) rotates, the three chuck claws (404) move away from the center synchronously along the three sliding grooves on the top of the locking chuck frame (4) until the outer side of the three arc plates (405) fits against the inner side of the toothed ring (5) without any looseness. Then the motor G (401) is turned off. At this time, the toothed ring (5) will be centered and restricted in the middle position of the top of the locking chuck frame (4), and can be fixed according to different toothed ring (5) middle dimensions. 2) Start motor A (102). The threaded shaft of motor A (102) rotates, driving the advance block (103) to slide backward along the inside of the advance frame (101). The advance block (103) synchronously drives the top motor B (104), turntable (105) and locking chuck frame (4) to move towards the grinding area. 3) When the rear end of the advancing block (103) is in contact with the rear end of the advancing frame (101), turn off motor A (102). At this time, the turntable (105) is located directly below the laser positioner (304). At this time, it can be determined that the center of the gear ring (5) is located directly below the laser positioner (304). Then, according to the radius of the gear ring (5), start the motor A (102) shaft to reverse. The advancing block (103) slides forward inside the advancing frame (101) at a distance that matches the radius of the gear ring (5). 4) Start motor E (302). Motor E (302) drives lifting block (303) to slide up and down along the inside of adjustment frame (301). Lifting block (303) synchronously drives angle frame (305), angle seat (307) and grinder (308) to rise and fall until the grinding head of grinder (308) is in contact with the surface of gear ring (5) to be ground. Then start grinder (308) to grind gear ring (5). 5) After starting motor B (104), the rotating shaft of motor B (104) drives the turntable (105) to rotate slowly and uniformly to avoid uneven grinding caused by excessive speed. The turntable (105) drives the gear ring (5) to rotate synchronously, so that the grinder (308) can grind the outer periphery of the gear ring (5). 6) Start the motor F (306). The shaft of the motor F (306) drives the angle seat (307) to rotate around its own axis. By observing the semi-circular angle scale plates on the left and right sides of the angle seat (307), adjust the grinder (308) at the front end of the angle seat (307) to the tilt grinding angle that matches the part to be ground on the gear ring (5).
