[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] refer to Figure 1 - Figure 13This invention provides a multi-station rapid repositioning ring rolling machine for wind turbine flanges, comprising a worktable 1, a rolling assembly, and an adjusting assembly. The top of the worktable 1 has two ring rolling positions 2, symmetrically arranged on both sides of the top of the worktable 1. Each ring rolling position 2 has multiple circumferentially arranged sliding grooves 3, and a circular groove 4 is formed on one side of the inner wall of each sliding groove 3. The rolling assembly includes a built-in hydraulic rod 5, one end of which is fixedly connected to a rotating motor 6. The output shaft of the rotating motor 6 is fixedly connected to a rotating pressure roller 7 via a coupling. A straight groove 8 is formed in the middle of each ring rolling position 2. The adjustment assembly includes a bidirectional lead screw 9 that passes through the straight groove 8 and is rotatably mounted. The positive and negative threads of the bidirectional lead screw 9 are respectively connected to two reciprocating moving tables 10. The reciprocating moving tables 10 are slidably mounted in the straight groove 8 and arranged symmetrically. An elastic telescopic rolling ring column 11 is slidably connected to the top of the reciprocating moving table 10. A rotating frame 14 is fixedly connected to one side of the worktable 1, and a support baffle 15 is fixedly connected to the other side of the worktable 1. A stabilizing bracket 37 is fixedly connected to one side of the support baffle 15. An auxiliary slide rod 38 is slidably connected inside the stabilizing bracket 37. A thread measuring rod 39 is fixedly connected to one end of the auxiliary slide rod 38.

[0023] During operation, the ring-rolling position 2 is located on top of the workbench 1. The wind turbine flange can be placed on the ring-rolling position 2 for ring rolling. Two ring-rolling positions 2 can be set up to roll rings simultaneously, or the material can be loaded and unloaded while rolling rings are being rolled. During synchronous ring rolling, the built-in hydraulic rods 5 at the two ring-rolling positions 2 are retracted as much as possible, moving the rotating pressure roller 7 to the outermost side of the circular groove 4, making it easier to place the wind turbine flange on the ring-rolling position 2. Then, the built-in hydraulic rods 5 work, pushing the rotating pressure roller 7 to move towards the inner side of the circular groove 4 until the rotating pressure roller 7 abuts against the wind turbine flange. Then, the rotating motor 6 drives the rotating pressure roller 7 to rotate, which is used to roll the surface of the wind turbine flange. At the same time, it can also drive the wind turbine flange to start rotating. For the inner ring of the wind turbine flange, the bidirectional screw 9 can rotate on the inner wall of the straight groove 8. As the wind turbine flange rotates, the rotation of the bidirectional screw 9 drives the two reciprocating moving tables 10 to move synchronously in opposite directions within the straight groove 8, thereby adjusting the elastic telescopic ring-rolling column 11. The lateral position allows it to adapt to flange inner rings of different specifications. The elastic telescopic design of the rolling ring column 11 provides buffering during rolling, avoiding flange deformation caused by rigid contact. The height adjustment can accommodate wind power flanges of different heights. The workbench 1 is fixedly supported by the rotating frame 14, and the support baffle 15 protects the inner side. The stabilizing bracket 37 is fixed on one side of the support baffle 15. The auxiliary slide rod 38 can slide inside the stabilizing bracket 37, and drive the thread measuring rod 39 to slide inside the stabilizing bracket 37 and the support baffle 15, thereby driving the positioning rotating cylinder 41 to move. When the positioning rotating cylinder 41 abuts against the surface of the flange, the readings of the thread measuring rod 39 and the inner surface of the support baffle 15 are the flange dimensions. The stabilizing bracket 37 ensures the stability of the auxiliary slide rod 38 and the thread measuring rod 39, and works with the support baffle 15 to prevent the auxiliary slide rod 38 and the thread measuring rod 39 from deflecting.

[0024] Figure 3 and Figure 11 As shown, a tension spring 40 is sleeved on the surface of the auxiliary slide rod 38. The two ends of the tension spring 40 are fixedly connected to one end of the auxiliary slide rod 38 and the stabilizing bracket 37, respectively. One end of the thread measuring rod 39 passes through the stabilizing bracket 37 and the support baffle 15 in sequence and extends to the inner side of the support baffle 15. The end of the thread measuring rod 39 located inside the support baffle 15 is fixedly connected to the positioning rotating cylinder 41. The thread measuring rod 39 located between the support baffle 15 and the positioning rotating cylinder 41 is threadedly connected to the reading measuring cap 42. One end of the bidirectional lead screw 9 passes through the worktable 1 and is connected to the external motor 13 through the coupling. A motor frame 12 is set below the external motor 13. The motor frame 12 is installed on the worktable 1, and the external motor 13 is installed on the motor frame 12.

[0025] During operation, the tension spring 40 ensures that the auxiliary slide bar 38 and the thread measuring rod 39 always tend to move towards the rolling ring position 2, while the reading measuring cap 42 can be pre-adjusted to a predetermined size. When the flange reaches the predetermined size, the reading measuring cap 42 will abut against the inner side of the support baffle 15 and limit its movement. The flange size can be measured by the thread measuring rod 39 to ensure the rolling ring accuracy. In this process, the reading measuring cap 42 can also be used to set a predetermined size value to achieve precise control of the rolling ring size. The motor frame 12 is fixedly supported on one side of the worktable 1, and the external motor 13 is fixedly supported on the top of the motor frame 12. The external motor 13 and the bidirectional lead screw 9 are fixed at one end on one side of the worktable 1, so that after the external motor 13 works, it drives the bidirectional lead screw 9 to rotate through the output shaft, thereby supplying power to the reciprocating moving table 10.

[0026] Figure 5 and Figure 9 As shown, an inclined top plate 16 is fixedly connected to the top of the support baffle 15, and an auxiliary bracket 17 is fixedly connected to the top of the inclined top plate 16. The number of auxiliary brackets 17 is set to two, and the two auxiliary brackets 17 are symmetrically arranged on both sides of the top of the inclined top plate 16. An external large hydraulic rod 18 is fixedly connected inside the auxiliary bracket 17. One end of the external large hydraulic rod 18 passes through the inclined top plate 16 and extends above the ring rolling position 2. A wedge block 19 is fixedly connected to the end of the external large hydraulic rod 18 near the ring rolling position 2. A fixed upright plate 20 is fixedly connected to the bottom of the wedge block 19. A motor cylinder 21 is fixedly connected to one side of the fixed upright plate 20. An internal motor 22 is fixedly connected inside the motor cylinder 21. A conical ring rolling roller 23 is fixedly connected to the output shaft of the internal motor 22 through a coupling. The conical ring rolling roller 23 is located on the side of the fixed upright plate 20 away from the motor cylinder 21. One end of the conical ring rolling roller 23 is rotatably connected to the surface of the fixed upright plate 20.

[0027] During operation, the inclined top plate 16 is fixedly installed by the support baffle 15, and the auxiliary bracket 17 is fixed on the top of the inclined top plate 16. Two auxiliary brackets 17 are set to install and fix two external large hydraulic rods 18. After the external large hydraulic rods 18 work, they drive the wedge block 19 to extend and retract, so as to adjust the different positions of the wedge block 19 on the ring rolling position 2. The bottom of the wedge block 19 is fixedly installed with a fixed upright plate 20. The motor cylinder 21 is fixedly installed on one side of the fixed upright plate 20. The motor cylinder 21 has an internal motor 22 installed inside and is protected. After the internal motor 22 works, it drives the conical ring rolling roller 23 to rotate on the other side of the fixed upright plate 20 through the output shaft, thereby rolling the wind turbine flange. In addition, when the height of the wind turbine flange is low, the conical ring rolling roller 23 is attached to the surface of the wind turbine flange and can also press the elastic telescopic ring rolling column 11 down, preventing the elastic telescopic ring rolling column 11 from blocking the conical ring rolling roller 23, thus ensuring that the surface of the wind turbine flange can be rolled.

[0028] like Figure 1 , Figure 2 and Figure 8 As shown, a rotating base cylinder 24 is rotatably connected inside the rotating frame 14. A rotating frustum 25 is fixedly connected to the surface of the rotating base cylinder 24. An electric telescopic rod 26 is fixedly connected to the top of the rotating frustum 25. A mechanical rotating frame 27 is fixedly connected to the top of the electric telescopic rod 26. The mechanical rotating frame 27 is rotatably connected to a first rotating rod 28, a second rotating rod 29, and a rotating hydraulic rod 30 in sequence. A clamping claw 31 is fixedly connected to one end of the rotating hydraulic rod 30. The rotating base cylinder 24, the rotating frustum 25, the first rotating rod 28, the second rotating rod 29, and the rotating hydraulic rod 30 are all controlled to rotate by an electric motor.

[0029] During operation, the wind turbine flange is gripped by the clamping claw 31 during loading and unloading. Subsequent conveying is controlled by an electric motor to rotate the rotating base cylinder 24, rotating platform 25, first rotating rod 28, second rotating rod 29, and rotating hydraulic rod 30 synchronously or individually. In this process, the rotation of the rotating base cylinder 24 drives the electric telescopic rod 26 to rotate, and the rotation of the rotating platform 25 drives the mechanical rotating frame 27 to rotate. The electric telescopic rod 26 drives the mechanical rotating frame 27 to rise and fall. Subsequently, the first rotating rod 28, second rotating rod 29, and rotating hydraulic rod 30 can all rotate relative to each other. The whole system is equivalent to the operation of a robotic arm, which can drive the clamping claw 31 to move in multiple positions to ensure the flexibility of loading and unloading.

[0030] like Figure 1 , Figure 6 and Figure 10 As shown, the bottom of the workbench 1 is fixedly connected with support legs 32, and the number of support legs 32 is set to four. T-shaped slide rails 33 are provided on both sides of the bottom of the workbench 1. A suction assembly is slidably connected to the bottom of the T-shaped slide rails 33. The suction assembly includes a vacuum suction chamber 34. Reciprocating wheels 35 are rotatably connected to both sides of the bottom of the vacuum suction chamber 34. T-shaped sliders 36 that are adapted to the T-shaped slide rails 33 are fixedly connected to the four corners of the top of the vacuum suction chamber 34. The top of the vacuum suction chamber 34 is slidably connected to the inner wall of the T-shaped slide rails 33 through the T-shaped sliders 36.

[0031] During operation, the worktable 1 is supported by the support leg 32. A T-shaped slide rail 33 is provided at the bottom of the worktable 1. The T-shaped slide rail 33 limits the material suction component. The material suction component mainly includes a vacuum suction chamber 34. The vacuum suction chamber 34 sucks in the uncooled crushed iron filings. During this suction process, the reciprocating wheel 35 can drive the vacuum suction chamber 34 to move back and forth at the bottom of the worktable 1. A T-shaped slider 36 is fixed at the top of the vacuum suction chamber 34. The T-shaped slider 36 is adapted to the T-shaped slide rail 33, thereby realizing the limiting function of the T-shaped slide rail 33. Overall, it can prevent the high-temperature iron filings from adhering to the circular groove 4 and the straight groove 8 and being cooled and shaped, which would affect subsequent work and further improve the adaptability of use.

[0032] Working Principle: Due to the inability to adjust the positioning and rolling ring positions during processing, this method is only suitable for workpieces of uniform size, and its adaptability needs improvement. First, the rolling ring position 2 is set on top of the workbench 1. The wind turbine flange can be placed on the rolling ring position 2 for rolling. Two rolling ring positions 2 can be set up for simultaneous rolling, or loading and unloading can be done while rolling. During synchronous rolling, the built-in hydraulic rods 5 at both rolling ring positions 2 retract as much as possible, moving the rotating pressure roller 7 to the outermost side of the circular groove 4, facilitating the placement of the wind turbine flange on the rolling ring position 2. Then, the built-in hydraulic rods 5 operate, pushing the rotating pressure roller 7 towards the inner side of the circular groove 4 until the rotating pressure roller 7 abuts against the wind turbine flange. Afterward, the rotating motor 6 drives the rotating pressure roller 7 to rotate, thus adjusting the wind turbine flange. The surface of the electric flange is rolled with a ring, which also drives the wind turbine flange to start rotating. For the inner ring of the wind turbine flange, the double-acting screw 9 can rotate on the inner wall of the straight groove 8. As the wind turbine flange rotates, the double-acting screw 9 drives the two reciprocating moving tables 10 to move synchronously in opposite directions in the straight groove 8, thereby adjusting the lateral position of the elastic telescopic rolling ring column 11 to adapt it to the inner ring of flanges of different specifications. The elastic telescopic design of the elastic telescopic rolling ring column 11 can provide buffer during rolling, avoiding rigid contact that could cause flange deformation. At the same time, the height adjustment can adapt to wind turbine flanges of different heights. The workbench 1 is fixedly supported by the rotating frame 14, and the support baffle 15 provides inner protection. A stabilizing bracket 37 is fixed to one side of the support baffle 15. An auxiliary slide rod 38 can slide inside the stabilizing bracket 37, driving the thread measuring rod 39 to slide within the stabilizing bracket 37 and the support baffle 15, thereby moving the positioning rotating cylinder 41. When the positioning rotating cylinder 41 abuts against the surface of the flange, the readings on the inner surface of the thread measuring rod 39 and the support baffle 15 represent the flange dimensions. The stabilizing bracket 37 ensures the stability of the auxiliary slide rod 38 and the thread measuring rod 39. The support baffle 15 prevents the auxiliary slide rod 38 and the thread measuring rod 39 from deflecting. The tension spring 40 ensures that the auxiliary slide rod 38 and the thread measuring rod 39 always tend to move towards the ring rolling position 2. The reading measuring cap 42 can be pre-adjusted to a predetermined size. When the flange reaches the predetermined size, the reading measuring cap 42 will abut against the inner side of the support baffle 15 and limit its movement. The flange size can be measured by the thread measuring rod 39 to ensure the ring rolling accuracy. In this process, the reading measuring cap 42 can also be used to set a predetermined size value to achieve precise control of the ring rolling size. At the same time, a motor frame 12 is fixedly supported on one side of the worktable 1. An external motor 13 is fixedly supported on the top of the motor frame 12. The external motor 13 and the bidirectional lead screw 9 are fixed at one end on one side of the worktable 1, so that after the external motor 13 works, it drives the bidirectional lead screw 9 to rotate through the output shaft, thereby supplying power to adjust the reciprocating moving table 10.In addition, the workbench 1 is fixedly supported by the rotating frame 14, and a support baffle 15 is also fixedly installed on one side of its top. The inclined top plate 16 is fixedly installed by the support baffle 15. The auxiliary bracket 17 is fixed on the top of the inclined top plate 16. Two auxiliary brackets 17 are provided to install and fix two external large hydraulic rods 18. After the external large hydraulic rods 18 work, they drive the wedge block 19 to extend and retract, so as to adjust the different positions of the wedge block 19 on the ring rolling position 2. The bottom of the wedge block 19 is fixed with a vertical plate 20. A motor cylinder 21 is fixedly installed on one side of the fixed plate 20. A protective built-in motor 22 is installed inside the motor cylinder 21. After the built-in motor 22 is working, it drives the conical rolling roller 23 to rotate on the other side of the fixed plate 20 through the output shaft, thereby rolling the wind turbine flange. In addition, when the wind turbine flange is low, the conical rolling roller 23 is attached to the surface of the wind turbine flange and can also press the elastic telescopic rolling column 11 down, preventing the elastic telescopic rolling column 11 from blocking the conical rolling roller 23, thus ensuring that the surface of the wind turbine flange can be rolled. Next, during loading and unloading, the wind turbine flange is gripped by the clamping claw 31. The subsequent conveying is controlled by an electric motor to rotate the rotating base cylinder 24, rotating platform 25, first rotating rod 28, second rotating rod 29, and rotating hydraulic rod 30 synchronously or individually. During this process, the rotation of the rotating base cylinder 24 drives the electric telescopic rod 26 to rotate, and the rotation of the rotating platform 25 drives the mechanical rotating frame 27 to rotate. The electric telescopic rod 26 drives the mechanical rotating frame 27 to rise and fall. Subsequently, the first rotating rod 28, second rotating rod 29, and rotating hydraulic rod 30 can all rotate relative to each other. The whole is equivalent to the operation of a robotic arm, which can drive the clamping claw 31 to move in multiple positions to ensure the flexibility of loading and unloading. Finally, the worktable 1 is supported by the support leg 32. A T-shaped slide rail 33 is provided at the bottom of the worktable 1. The T-shaped slide rail 33 limits the material suction component. The material suction component mainly includes a vacuum suction chamber 34. The vacuum suction chamber 34 sucks in the uncooled crushed iron filings. During this suction process, the reciprocating wheel 35 can drive the vacuum suction chamber 34 to move back and forth at the bottom of the worktable 1. A T-shaped slider 36 is fixed at the top of the vacuum suction chamber 34. The T-shaped slider 36 is adapted to the T-shaped slide rail 33, thereby realizing the limiting function of the T-shaped slide rail 33. Overall, it can prevent the high-temperature iron filings from adhering to the circular groove 4 and the straight groove 8 and being cooled and shaped, which would affect subsequent work and further improve the adaptability of use.The system features two symmetrically arranged ring-rolling positions 2, enabling multi-station synchronous processing of wind turbine flanges and effectively improving production efficiency. The rolling assembly includes a built-in hydraulic rod 5 that drives the rotating pressure roller 7 to move flexibly along the sliding groove 3. Combined with the rotating motor 6 driving the rotating pressure roller 7, the pressure position and force can be adjusted according to the flange size, ensuring a stable and controllable ring-rolling process. The adjustment assembly uses a bidirectional screw 9 to rotate two reciprocating moving tables 10, which move synchronously in opposite directions within the straight groove 8. This adjusts the lateral position of the elastic telescopic ring-rolling column 11 to adapt to flange inner rings of different specifications. The elastic telescopic design provides cushioning during ring rolling, preventing flange deformation caused by rigid contact. Simultaneously, the two ring-rolling positions 2 can operate independently or via the adjustment assembly. This system enables collaborative processing to meet diverse production needs, solving the problems of low processing efficiency and poor dimensional adaptability of traditional single-station ring rolling machines. Furthermore, an electric telescopic rod 26 is installed, which can rotate on the rotating platform 25 and simultaneously drive the mechanical rotating frame 27 to adjust the direction of the clamping jaws 31. Additionally, a first rotating rod 28 and a second rotating rod 29 are provided, and the clamping jaws 31 are used to clamp the wind turbine flange. The entire system allows for multi-angle adjustment, ensuring stability during placement. Furthermore, a vacuum suction chamber 34 is provided to suck in the iron filings generated after ring rolling, preventing them from adhering to the circular groove 4 and straight groove 8 and undergoing cooling and shaping, thus affecting subsequent work and further improving the adaptability of the machine.
