Description
Technical Field
[0001] This utility model relates to the technical field of wind turbine blade nesting processing equipment, and in particular to a device for removing burrs from the through holes of wind turbine blade nesting. Background Technology
[0002] Casting is a common process in the nesting of wind turbine blades. Sand casting equipment first creates a sand mold that matches the shape of the nested blades. Molten metal is then poured into the mold cavity. After the molten metal cools and solidifies, a wind turbine blank with nested through holes is formed. For example, large gravity casting machines are often used to cast large wind turbine blades, utilizing gravity to fill the mold with molten metal and ensure the formation of the nested structure.
[0003] During the production of wind turbine blades, burrs generated by nested through-holes can affect the appearance quality of the blades, making their surfaces uneven and rough. These burrs can also scratch other components during subsequent assembly, leading to assembly difficulties and even affecting the normal operation of the entire equipment. Equipment for removing burrs from nested through-holes in wind turbine blades can precisely remove these burrs, making the edges of the through-holes smooth and flat, meeting the surface quality standards required by design, thereby improving the overall quality of the wind turbine blades and reducing the product defect rate caused by burr problems.
[0004] In existing technologies, some workbenches are difficult to clean, generating a large amount of metal shavings or other dust during the deburring of the nested through-holes in the fan blades. If the equipment is difficult to clean, this dust will adhere to the transmission components, bearings, guide rails, and other parts of the equipment. As the equipment operates, the dust enters the mating gaps of the components, acting as an abrasive and exacerbating friction and wear between them. For example, when bearings operate in a dusty environment, the surfaces of the balls and raceways will be gradually scratched, leading to decreased bearing precision, shortened service life, and ultimately equipment malfunction, affecting production progress. Therefore, a device for removing burrs from the nested through-holes of the fan blades is proposed to solve the above problems. Utility Model Content

[0032] Example 1
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a device for removing burrs from nested through holes in a fan blade. The device includes a worktable 3, with movable components fixedly connected to both sides of the top of the worktable 3. A fixed box 4 is fixedly connected to the top of the worktable 3, providing a stable foundation for the entire device and ensuring precision during processing. This ensures stable operation in subsequent steps. A motor 5 is installed on the inner wall of the fixed box 4, and a support rod 6 is fixedly connected to the drive end of the motor 5. The motor 5 drives a milling cutter 7 to remove burrs, ensuring high efficiency and consistency in the processing. The powerful motor 5 enables the milling cutter 7 to process stably and quickly, improving production efficiency. A milling cutter 7 is fixedly connected to one side of the support rod 6. The milling cutter 7 is the core component for deburring, using its high-speed rotation to cut away excess material from the workpiece surface. The design of the milling cutter 7 allows it to precisely cut into the nest, removing burrs without damaging other parts.
[0034] The top of the moving component is equipped with a sliding frame 9, and the bottom of the sliding frame 9 is fixedly connected to a fixing block 10 to achieve precise positioning and movement during processing. The sliding frame 9 provides greater flexibility, allowing the equipment to adapt to workpieces of different sizes. Multiple springs 11 are fixedly connected to the inner wall of the fixing block 10, and a sliding plate 12 is fixedly connected to the bottom of the multiple springs 11. The design of the springs 11 can effectively absorb vibration and maintain the stability of the sliding plate 12, ensuring that the brush 13 always maintains good contact during the cleaning process.
[0035] Multiple brushes 13 are fixedly connected to the bottom of the sliding plate 12. The brushes 13 are used to clean impurities generated during processing, keeping the working environment clean and tidy. The cleaning by the brushes 13 can greatly reduce the impact of impurities on subsequent processing and improve the overall production quality. The top of the sliding frame 9 is equipped with a mounting component. The moving component includes two slide rails 8. The bottom of the slide rails 8 is fixedly connected to the top of the worktable 3 to achieve smooth movement of the equipment. The design of the slide rails 8 allows the sliding frame 9 to move smoothly on the worktable 3, ensuring the accuracy and stability of each movement. The inner wall of the sliding frame 9 is slidably connected to the outside of the slide rails 8 by a slider, providing the equipment with multi-directional adjustment capabilities. Through this design, the equipment can flexibly cope with the processing requirements of different workpieces, thereby improving the flexibility of the production line.
[0036] Example 2
[0037] refer to Figure 1 , Figure 3 and Figure 4 An electric push rod 16 is fixedly connected to the top of the workbench 3. The drive end of the electric push rod 16 is fixedly connected to one side of the sliding frame 9. The application of the electric push rod 16 can quickly and effectively push the sliding frame 9 to achieve precise positioning and movement. Through electric push, not only is the processing efficiency improved, but the risk of manual operation is also reduced. Support frames 2 are fixedly connected to the four corners of the bottom of the workbench 3. The bottom of the multiple support frames 2 is fixedly connected to the base 1. The design of the support frame 2 improves the overall stability of the equipment, making it less prone to vibration during processing, thereby ensuring the accuracy and safety of processing. A collection box 15 for collecting impurities is fixedly connected to the top of the base 1. The setting of the collection box 15 can efficiently collect the impurities generated after processing, avoiding environmental pollution. Through effective waste collection, the cleanliness and orderliness of the production process are ensured. Two discharge ports 14 are fixedly connected to the through hole of the workbench 3. The discharge ports 14 provide a convenient way to discharge the impurities generated during processing into the collection box 15, ensuring the cleanliness and efficient use of the work area.
[0038] The mounting assembly includes a square block 17, the bottom of which is fixedly connected to the top of the sliding frame 9. The design of the square block 17 allows for flexible adjustment to adapt to different workpiece requirements, improving the versatility of the equipment. A threaded rod 23 is threadedly connected to the top of the square block 17, and a hollow column 18 is fixedly connected to one side of the square block 17. By adjusting the threaded rod 23, the contact depth with the nest can be precisely controlled, thereby affecting the deburring effect and ensuring that the processing quality meets the standards. A sleeve 20 is provided on the inner wall of the hollow column 18, and multiple square openings 21 are provided on the outside of the sleeve 20. These square openings 21 are designed according to the shape of the workpiece to achieve more comprehensive processing coverage and avoid any omissions. Multiple connecting rods 19 are rotatably connected to the inner wall of the hollow column 18. The connecting rods 19 are movably connected to the inner wall of the square openings 21. With the flexible movement of the connecting rods 19, the nest can be effectively resisted, fixing the workpiece in the processing position. This setting ensures that the workpiece will not shift during processing, improving the processing accuracy.
[0039] A handwheel 24 is fixedly connected to one side of the threaded rod 23, and a handwheel 22 is fixedly connected to one side of the sleeve 20. The handwheel design allows the operator to easily adjust the position of the sleeve 20, thereby quickly locking the required processing range and improving the convenience and flexibility of operation. The outer side of the sliding plate 12 is slidably connected to the inner wall of the fixed block 10, and the bottom of the sliding frame 9 is slidably connected to the top of the worktable 3. This connection method ensures the stability of the equipment when moving, prevents jamming, and improves the smoothness of work. Multiple square openings 21 are evenly distributed on the outside of the sleeve 20, and the connecting rod 19 is movably connected to the inner wall of the square openings 21. The evenly distributed design helps to improve the balance of the entire equipment and ensures that the workpiece will not be damaged due to uneven force at a certain point during processing.
[0040] Work steps
[0041] When the equipment is needed, the nest to be processed is placed on the inner wall of the sleeve 20. Then, by turning the first handwheel 22, the sleeve 20 is rotated. The rotation of the sleeve 20 causes the connecting rod 19 to rotate, which in turn holds the nest in place. Then, by turning the second handwheel 24, the threaded rod 23 is rotated. The threaded rod 23 then holds the first handwheel 22. The thread between the first handwheel 22 and the square block 17 fixes the rotation position of the sleeve 20, thus restricting the nest.
[0042] The process begins by activating the electric push rod 16, which moves the sliding frame 9. This movement of the sliding frame 9 causes the square block 17 to move, restricting the nested part. When the nested part reaches the desired position, the motor 5 is activated, which in turn drives the support rod 6, causing the milling cutter 7 to rotate and deburr the nested part. Impurities generated during this process fall through the discharge port 14 into the collection box 15, while some fall onto the top of the worktable 3. The movement of the sliding frame 9 moves the fixing block 10, causing the sliding plate 12 to move the brush 13. The brush 13 contacts the top of the worktable 3, sweeping impurities from the top of the worktable 3 into the discharge port 14, where they ultimately fall into the collection box 15. The spring 11 ensures that the sliding plate 12 pushes the brush 13, maintaining constant contact between the brush 13 and the top of the worktable 3, thus improving the brush 13's lifespan and cleaning effectiveness.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
