[0016] The machining tool for wind turbine flange is used, and the machining method includes the following steps:

[0017] S1. Installation of the flange: The hydraulic cylinder drives the rotating plate to a position parallel to the base plate. At the same time, the load-bearing block supports one end of the rotating plate. At this time, the flange is placed on the disc on the rotating plate and placed between the first clamping block and the second clamping block. It is then clamped and fixed by the clamping assembly.

The rod continues to drive the nut sleeve and the first clamping block to move, thereby positioning the flange for the first time. After that, the second motor is turned off again, and the pushing member inside the mobile bin pulls back the pushing block to reset it. At the same time, the elastic potential energy of the spring drives the clamping column to reset and move it out of the slot. At this time, the nut sleeve and the first clamping block are disconnected, and then the second motor is started again to move the nut sleeve to the second clamping block. The above steps are used to move the second clamping block and position the flange for the second time. Finally, the electromagnetic adsorption bar is energized to fix the positions of the first clamping block and the second clamping block, thereby completing the clamping and fixing of the inner and outer sides of the flange.

[0019] S3. Processing of flange parts: The hydraulic cylinder is started to push the rotating plate to a position perpendicular to the base plate, and then the cutting mechanism and the cooling mechanism are driven to move by the first and second robotic arms respectively, so as to adjust the cutting position. Then, the first motor is started to drive the gear to rotate, thereby driving the rotating tube to rotate, and then driving the flange to rotate. At the same time, the hydraulic telescopic rod drives the feed motion provided by the cutting mechanism and the vertical movement motion provided by the Y-shaped drive seat, so as to perform cutting processing on the flange part.

An empty slot 23 is provided at the position where the first clamping block 20 and the second clamping block 21 are aligned with the strip groove 17. The nut sleeve moves to the empty slot 23 and is clamped and fixed between the first clamping block 20 and the second clamping block 21.

[0040] The nut sleeve includes a moving warehouse 24, a limiting warehouse 25, a push block 26, a wedge 27, a limiting ring 28, a spring 29, a clamping column 30 and a clamping groove 31. One end of the moving warehouse 24 is threadedly connected to the threaded rod 18. A limiting warehouse 25 is provided inside the moving warehouse 24, and a pushing member 49 is provided inside the limiting warehouse 25. The pushing member 49 can adopt the principle of opposite poles repelling each other of the electromagnet to push the pushing block to move, or it can be pushed by an electric push rod. The end of the pushing member 49 is connected to the pushing block 26, and the pushing block 26 is slidably connected to the limiting warehouse 25. A clamping column 30 is penetrated on the side wall of the moving warehouse 24 away from the end of the threaded rod 18, and a limiting ring 28 is provided on the inner side of the clamping column 30. A spring 29 is sleeved between the limiting ring 28 and the inner wall of the moving warehouse 24. The end of the clamping column 30 close to the limiting ring 28 is provided with a wedge 27 adapted to the pushing block 26, and a clamping groove 31 is provided on the inner wall of the empty slot 23.

[0041] The second drive assembly includes a second motor 38, a first bevel gear 39 and a second bevel gear 40. The second motor 38 is fixed at the center position of one side of the disc 7. The output end of the second motor 38 passes through the disc 7 and is fixed with the first bevel gear 39. The four groups of threaded rods 18 are each fixed with a second bevel gear 40 at one end close to the first bevel gear 39. The first bevel gear 39 is meshed with the four groups of second bevel gears 40.

[0042] Since the diameter of the wind turbine flange is generally 6m upward and its own gravity is large, it is particularly necessary to ensure its stability during vertical processing. Therefore, the present device is provided with a first clamping block 20 and a second clamping block 21, and the first clamping block 20 and the second clamping block 21 are fixed in the limit groove 19 by electromagnetic adsorption. When the first clamping block 20 and the second clamping block 21 are moved, the second motor 38 is started, and the second motor 38 drives the first bevel gear 39 to rotate, thereby driving the four groups of second bevel gears 40 to rotate synchronously, and then driving the four groups of threaded rods 18 to rotate, thereby adjusting the position of the nut sleeve. When the nut sleeve moves to the first clamping block 20, and the second sensor 34 on the nut sleeve moving bin 24 is aligned with the first sensor 33 on the first clamping block 20, the second motor 38 is turned off at this time, and the push block 26 is pushed to move by the push member 49 inside the moving bin 24, so that the push block 26 pushes the wedge block 27 to move, and then pushes the clamping column 30 out. The second motor 38 is then started again to move the nut sleeve to the second clamping block 21, and the second motor 38 is started again. The threaded rod 18 continues to drive the nut sleeve and the first clamping block 20 to move, thereby positioning the flange for the first time. After that, the second motor 38 is closed again, and the pusher 49 inside the movable chamber 24 pulls back the push block 26 to reset. At the same time, the elastic potential energy of the spring 29 drives the clamping column 30 to reset and move it out of the slot 31. At this time, the nut sleeve is disconnected from the first clamping block 20. After that, the second motor 38 is started again to move the nut sleeve to the second clamping block 21, and the second clamping block 21 is moved and the flange is positioned for the second time through the above steps. Finally, the electromagnetic adsorption strip 22 is energized to fix the positions of the first clamping block 20 and the second clamping block 21, thereby completing the clamping and fixing of the inner and outer sides of the flange. The stability of the flange during vertical processing is ensured by the two-way clamping and fixing method.

[0043] A T-shaped block 32 is provided on each of the first clamping block 20 and the second clamping block 21, and the T-shaped block 32 is inserted into the limiting groove 19.

A first sensor 33 is provided on the side of the first clamping block 20 and the second clamping block 21 away from the flange, and a second sensor 34 adapted to the first sensor 33 is provided on the top and bottom of the mobile warehouse 24.

[0044] At the same time, the tool automatically determines the alignment between the clamping column 30 and the clamping slot 31 through the induction between the first sensor 33 and the second sensor 34, which is relatively convenient.

[0045] The first driving assembly includes a first motor 35 , a gear 36 and a gear ring 37 . The first motor 35 is fixed on the rotating plate 3 , a gear 36 is fixed on the output end of the first motor 35 , and a gear ring 37 is fixed on the rotating tube 6 . The gear 36 is meshed with the gear ring 37 .

[0046] By starting the first motor 35 , the gear 36 is driven to rotate, thereby driving the rotating tube 6 to rotate through the gear ring 37 , and further driving the flange on the disc 7 to rotate, cooperating with the cutting mechanism 11 for processing.

[0047] The adjustment assembly includes a hydraulic cylinder 41 . A plurality of hydraulic cylinders 41 are hinged on the base plate 1 . The output ends of the hydraulic cylinders 41 are hinged to the side walls of the rotating plate 3 .

[0048] The driving seat includes a connecting seat 42, a rotating block 43, a hydraulic telescopic rod 44 and a mounting mechanism. The rotating block 43 is rotatably mounted on the bottom of the connecting seat 42. The end of the rotating block 43 is provided with a hydraulic telescopic rod 44.

The T-shaped moving block 46 is provided with a mounting groove 47. The cutting mechanism 11 and the cooling mechanism 12 are both fixed in the mounting groove 47 by the limiting bolt 48.

[0050] By designing a convenient detachable mechanism, it is convenient to install and replace the cutting mechanism 11 or the cooling mechanism 12, which greatly increases the processing efficiency of the device.

[0051] A machining tool for a wind power flange is used, and the machining method includes the following steps:

[0052] S1. Installation of the flange: The hydraulic cylinder 41 drives the rotating plate 3 to move to a position parallel to the base plate 1. At the same time, the load-bearing block 4 supports one end of the rotating plate 3. At this time, the flange is placed on the disc 7 on the rotating plate 3 and placed between the first clamping block 20 and the second clamping block 21. It is then clamped and fixed by the clamping assembly.

[0053] S2, the flange is fixed by starting the second motor 38, the second motor 38 drives the first bevel gear 39 to rotate, thereby driving the four sets of second bevel gears 40 to rotate synchronously, and then driving the four sets of threaded rods 18 to rotate, so as to adjust the position of the nut sleeve. When the nut sleeve moves to the first clamping block 20, and the second sensor 34 on the nut sleeve moving bin 24 is aligned with the first sensor 33 on the first clamping block 20, the second motor 38 is turned off at this time, and the pusher 49 inside the moving bin 24 pushes the push block 26 to move, so that the push block 26 pushes the wedge block 27 to move, and then pushes the card column 30 out and snaps into the card slot 31. At this time, the nut sleeve is connected to the first clamping block 20, and the second motor 3 is started again. 8. The threaded rod 18 continues to drive the nut sleeve and the first clamping block 20 to move, thereby positioning the flange for the first time. After that, the second motor 38 is turned off again, and the pusher 49 inside the movable chamber 24 pulls back the push block 26 to reset. At the same time, the elastic potential energy of the spring 29 drives the clamping column 30 to reset and move it out of the slot 31. At this time, the nut sleeve and the first clamping block 20 are disconnected. Then, the second motor 38 is started again to move the nut sleeve to the second clamping block 21. Through the above steps, the second clamping block 21 is moved and the flange is positioned for the second time. Finally, the electromagnetic adsorption strip 22 is energized to fix the positions of the first clamping block 20 and the second clamping block 21, thereby completing the clamping and fixing of the inner and outer sides of the flange.

[0054] S3. Processing of flange parts: The hydraulic cylinder 41 is started to push the rotating plate 3 to move to a position perpendicular to the base plate 1. The cutting mechanism 11 and the cooling mechanism 12 are driven to move by the first robotic arm 9 and the second robotic arm 10 respectively, thereby adjusting the cutting position. The first motor 35 is then started to drive the gear 36 to rotate, which in turn drives the rotating tube 6 to rotate, thereby driving the flange part to rotate. At the same time, the hydraulic telescopic rod 44 drives the feed motion provided by the cutting mechanism 11 and the vertical movement motion provided by the Y-shaped drive seat 45, thereby cutting the flange part.

Installation of the flange: The hydraulic cylinder (41) drives the rotating plate (3) to move to a position parallel to the bottom plate (1), and the load-bearing block (4) supports one end of the rotating plate (3). At this time, the flange is placed on the disc (7) on the rotating plate (3), and is placed between the first clamping block (20) and the second clamping block (21), and then clamped and fixed by the clamping assembly; S2. Fixing the flange, by starting the second motor (38), the second motor (38) drives the first bevel gear (39) to rotate, thereby driving the four sets of second bevel gears (40) to rotate synchronously, and then driving the four sets of threaded rods (18) to rotate, thereby adjusting the position of the nut sleeve. When the nut sleeve moves to the first clamping block (20), and the second sensor (34) on the nut sleeve moving bin (24) is aligned with the first sensor (33) on the first clamping block (20), the second motor (38) is turned off, and the pusher (49) inside the moving bin (24) pushes the pusher block (26) to move, so that the pusher block (26) pushes the wedge block (27) to move, and then pushes the clamping column (30) out and clamps it into the clamping slot (31). At this time, the nut sleeve is connected to the first clamping block (20), and the second motor is started again. The machine (38) is driven by the threaded rod (18), and the nut sleeve and the first clamping block (20) are continuously driven to move, thereby positioning the flange for the first time. After that, the second motor (38) is turned off again, and the pusher (49) inside the movable chamber (24) is used to pull back the pusher block (26) to reset it. At the same time, the elastic potential energy of the spring (29) is used to drive the clamping column (30) to reset it and move it out of the clamping slot (31). At this time, the nut sleeve is disconnected from the first clamping block (20). After that, the second motor (38) is started again to move the nut sleeve to the second clamping block (21). The second clamping block (21) is moved and the flange is positioned for the second time through the above steps. Finally, the electromagnetic adsorption strip (22) is energized to fix the positions of the first clamping block (20) and the second clamping block (21), thereby completing the clamping and fixing of the inner and outer sides of the flange. S3. Processing of the flange: The hydraulic cylinder (41) is started to push the rotating plate (3) to move to a position perpendicular to the bottom plate (1), and then the first mechanical arm (9) and the second mechanical arm (10) are used to drive the cutting mechanism (11) and the cooling mechanism (12) to move, thereby adjusting the cutting position. Then, the first motor (35) is started to drive the gear (36) to rotate, thereby driving the rotating tube (6) to rotate, and then driving the flange to rotate. At the same time, the hydraulic telescopic rod (44) drives the feeding motion provided by the cutting mechanism (11) and the vertical movement motion provided by the Y-shaped driving seat (45), thereby cutting the flange.
