Description

Technical Field

[0001] This utility model relates to the field of wind turbine flange fixing fixture technology, specifically a height equalization fixture for fixing wind turbine flanges during machining. Background Technology

[0002] Wind turbine flange machining and fixing fixtures are specially designed for fixing and supporting wind turbine flanges during machining and installation. The fixtures are usually made of high-strength, corrosion-resistant materials to ensure long-term stable operation in harsh wind power environments. The fixtures can closely fit the shape and size of the wind turbine flange, thereby providing reliable fixing and support. The fixtures can firmly fix the wind turbine flange and prevent it from moving or deforming during machining or installation.

[0003] However, existing tooling for machining and fixing wind turbine flanges cannot be adjusted according to the height of the wind turbine flanges, resulting in inaccurate positioning of the wind turbine flanges during installation. Positioning errors affect the docking accuracy between the wind turbine flange and the machine end face of the wind turbine flange, which in turn affects the stability and operating efficiency of the entire wind turbine generator set. The tooling cannot adapt to wind turbine flanges of different heights, resulting in uneven stress on the contact surface between the tooling and the wind turbine flange. The tooling may be damaged due to excessive local pressure, or accelerated wear due to uneven stress over a long period of time. This not only increases maintenance costs but also affects the service life of the tooling. Utility Model Content

It has the advantage that the fixing fixture can be adjusted according to the height of the wind turbine flange, thus solving the problem that the fixing fixture cannot be adjusted to limit the height of the wind turbine flange for stable fixing.

[0005] To achieve the goal of adjusting the fixed fixture for wind turbine flange machining according to the height of the wind turbine flange, this utility model provides the following technical solution: A height-equalizing fixture for fixing wind turbine flange machining includes a reinforced fixing base. The reinforced fixing base has an internal placement groove. A movable pressing component is installed on the top surface of the reinforced fixing base.

The stepper motor is mounted on the top surface of the reinforced fixed base, and the ball screw is mounted on the outer surface of the output end of the stepper motor. A screw slider is mounted on the outer surface of the ball screw.

[0007] As a preferred technical solution of this utility model, the top surface of the reinforced fixed base is equipped with four movable slide rails, and two movable sliders are movably installed on the outer surface of each of the four movable slide rails.

[0008] As a preferred embodiment of this utility model, the top surfaces of the eight movable sliders are fixedly connected to the bottom surface of the base plate, and the top surface of the lead screw slider is fixedly connected to the bottom surface of the base plate.

[0012] Compared with the prior art, this utility model provides a height-equalizing tooling for fixing wind turbine flanges during machining, which has the following advantages:

[0013] This height-equalizing fixture, used for fixing wind turbine flanges during machining, moves a secondary fixture support within a lifting groove via a gear rack. This allows a rubber arc-shaped pressure block to press against the top of the wind turbine flange. The height of the secondary fixture support is equal to the height of the wind turbine flange, enabling more accurate positioning of the wind turbine flange on the machine face during installation. This reduces errors and deviations during installation, improving installation precision.

[0019] 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.

[0020] Please see Figures 1-4This utility model discloses a height-equalizing fixture for machining and fixing wind turbine flanges, including a reinforced fixing base 1. The reinforced fixing base 1 has an internal placement groove 9. A movable pressing component is mounted on the top surface of the reinforced fixing base 1. A base plate 5 is mounted on the outer surface of the movable pressing component. Two main fixture supports 6 are mounted on the top surface of the base plate 5. Each of the two main fixture supports 6 has a lifting groove 7 inside. A secondary fixture support 8 is movably mounted on the inner wall of each of the two lifting grooves 7. A gear rack 14 is mounted on one end surface of each of the two secondary fixture supports 8. A lifting power component is mounted on the outer surface of each of the two main fixture supports 6. A pressure block slider 17 is mounted on one end surface of each of the two secondary fixture supports 8. A rubber arc pressure block 18 is mounted on the outer surface of each of the two pressure block sliders 17. Two angle deflection components are mounted on the outer surface of the reinforced fixing base 1. The lifting power component includes a connecting plate 10 and a first motor 11. The connecting plate 10 is mounted on the outer surface of both main fixture supports 6. The first motor 11 is mounted on the connecting plate 10. On the top surface of plate 10, on the outer surface of the output end of the first motor 11, a first shaft 12 is mounted. Two drive gears 13 are mounted on the outer surface of the first shaft 12. The outer surface of the drive gears 13 meshes with the outer surface of the gear rack 14. Two moving grooves 15 are opened inside the connecting plate 10. The height of the auxiliary tooling bracket 8 is the same as the height of the wind turbine flange, which allows the wind turbine flange to be more accurately positioned on the end face of the wind turbine flange during installation, reducing errors and deviations during installation and improving installation accuracy. The rubber arc pressure block 18 presses on the top of the wind turbine flange, which helps to ensure that the wind turbine flange remains parallel and aligned with the end face of the wind turbine flange during installation. Precise alignment can reduce vibration and wear caused by deviation, and improve the operating efficiency of the entire wind turbine generator set. The rubber arc pressure block 18 not only provides pressure, but also has a certain anti-slip function. During the installation of the wind turbine flange, the rubber arc pressure block 18 can prevent the wind turbine flange from sliding due to vibration or external force, thereby enhancing the safety and stability of the installation.

[0021] The movable extrusion assembly includes a stepper motor 3 and a ball screw 22. The stepper motor 3 is mounted on the top surface of the reinforced base 1, and the ball screw 22 is mounted on the outer surface of the output end of the stepper motor 3. A screw slider 16 is mounted on the outer surface of the ball screw 22. Four movable slide rails 2 are mounted on the top surface of the reinforced base 1. Two movable sliders 4 are movably mounted on the outer surface of each of the four movable slide rails 2. The top surfaces of the eight movable sliders 4 are fixedly connected to the bottom surface of the base plate 5. The top surfaces of the screw sliders 16 are fixedly connected to the bottom surface of the base plate 5, so that the base plate 5 stably drives the main tooling bracket 6 and the auxiliary tooling bracket 8 to move, thereby allowing the main tooling bracket 6 and the auxiliary tooling bracket 8 to contact the wind turbine flange and support it. The main tooling bracket 6 and the auxiliary tooling bracket 8 can be adjusted in support position as needed to adapt to wind turbine flanges of different sizes and shapes.

[0022] The angle deflection assembly includes a second motor 19 and a second shaft 20. The second motor 19 is mounted on the top surface of the reinforced base 1, and the second shaft 20 is mounted on the outer surface of the output end of the second motor 19. A support plate 21 is mounted on the outer surface of the output end of the second motor 19 to facilitate the placement of the wind turbine flange in the placement slot 9 of the reinforced base 1. This allows the wind turbine flange to be placed quickly in the placement slot 9 of the reinforced base 1, greatly improving the installation efficiency and shortening the installation time. The support plate 21 is then reset to support the wind turbine flange.

[0023] The working principle and usage process of this utility model are as follows: When installing and debugging a wind turbine flange on the end face of the wind turbine flange machine, the wind turbine flange needs to be placed in the placement slot 9 of the reinforced fixing base 1 by a crane. First, the controller controls the two second motors 19 to work. The second motors 19 drive the second shaft 20 to rotate. The second shaft 20 drives the two support plates 21 to deflect at an angle, so that the vertical support plates 21 are tilted, which makes it easier to place the wind turbine flange in the placement slot 9 of the reinforced fixing base 1. This quickly places the wind turbine flange in the placement slot 9 of the reinforced fixing base 1, which greatly improves the installation efficiency and shortens the installation time. Then, the support plates 21 are reset to support the wind turbine flange.

[0024] The controller controls the first motor 11 to operate. The first motor 11 drives the first shaft 12 to rotate, which in turn drives two drive gears 13 to rotate. The outer surfaces of the drive gears 13 mesh with the outer surfaces of the gear rack 14, causing the gear rack 14 to move within the lifting groove 7 and the moving groove 15. This ensures that the height of the auxiliary tooling bracket 8 is equal to the height of the wind turbine flange, and that the rubber arc-shaped pressure block 18 presses against the top of the wind turbine flange. The equal height of the auxiliary tooling bracket 8 with the wind turbine flange ensures that the wind turbine flange... During installation, the rubber arc-shaped pressure block 18 can be more accurately positioned on the end face of the wind turbine flange, reducing errors and deviations during installation and improving installation accuracy. The rubber arc-shaped pressure block 18 presses on the top of the wind turbine flange, helping to ensure that the wind turbine flange remains parallel and aligned with the end face of the wind turbine flange during installation. Precise alignment can reduce vibration and wear caused by deviation, improving the operating efficiency of the entire wind turbine generator set. The rubber arc-shaped pressure block 18 not only provides pressure but also has a certain anti-slip function. During the installation of the wind turbine flange, the rubber arc-shaped pressure block 18 can prevent the wind turbine flange from sliding due to vibration or external force, thereby enhancing the safety and stability of the installation.

[0025] The stepper motor 3 is then controlled by the controller to operate, and the stepper motor 3 drives the ball screw 22 to rotate. The ball screw 22 and the screw slider 16 cooperate with each other, so that the base plate 5 drives the eight movable sliders 4 to move stably on the movable slide rail 2. This causes the base plate 5 to move the main tooling bracket 6 and the auxiliary tooling bracket 8 stably, so that the main tooling bracket 6 and the auxiliary tooling bracket 8 contact the wind turbine flange and support it. The main tooling bracket 6 and the auxiliary tooling bracket 8 can be adjusted in support position as needed to adapt to wind turbine flanges of different sizes and shapes.
