Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of skin processing, and specifically to a processing device for the leading edge skin of an aircraft wing. Background Art
[0002] The leading edge skin of an aircraft wing is a key component of the wing structure, undertaking various important functions and being crucial for the performance and safety of the aircraft. The leading edge skin of the wing usually adopts a smooth curved surface design to reduce air resistance during flight, and its shape is optimized according to the aerodynamic layout and flight requirements of the aircraft. Common shapes include circular arcs, ellipses, etc. To ensure the strength and stiffness of the leading edge skin while reducing weight, internal support structures such as stiffeners and ribs are often used. These support structures and the skin together form an integral whole to bear various loads during flight.
[0003] The grinding of the leading edge skin of an aircraft wing is a key process in aircraft maintenance and manufacturing. The surface smoothness of the leading edge skin of an aircraft wing is a core element to ensure flight performance, safety, and economy. The friction coefficient of a smooth surface (Ra≤0.8μm) can be reduced by 10%-20% compared to a rough surface, which has an important impact on flight performance and safety. However, most traditional aircraft skin grinding and processing are carried out manually. Manual grinding is prone to geometric shape deviation, and the curvature radius error of the leading edge of the wing may exceed ±0.2mm, affecting the accuracy of airfoil design. In extreme cases, the entire skin needs to be replaced. Moreover, manual grinding requires staying close to the grinding point for a long time, resulting in long-term exposure to areas with excessive harmful particulate matter such as aluminum powder and composite material fibers, increasing the risk of pneumoconiosis.
[0004] Combining the above problems, we will find that it is very difficult to avoid the above-mentioned problems simultaneously when the existing products on the market are in use. And even if these problems can be solved, external tools need to be used for cooperation, thus failing to achieve the desired effect.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the forming mold stretches the skin raw material to contact with the grinding belt in the grinding unit, the first motor can drive the first transmission wheel to rotate. Since the first transmission wheel, the second transmission wheel and the third transmission wheel are connected through the grinding belt transmission, the grinding belt drives the second transmission wheel and the third transmission wheel to rotate while rotating with the first transmission wheel, and the second transmission wheel and the third transmission wheel support and maintain tension on the grinding belt. The adaptive frame elastically supported by the spring makes the grinding belt adaptively adjust to fit the surface of the skin body more closely. The moving mechanism can reciprocate along the surface of the skin body, driving the grinding unit to reciprocately grind the surface of the skin body. The dust hood can be regarded as the input end of the dust removal unit, which is fixedly connected to both sides of the grinding belt through the moving frame. When the fan is in operation, negative pressure is generated at the port of the dust hood, so that dust generated when the grinding belt grinds the skin raw material is sucked in, and the dust is transported to the cavity dust filter bag of the dust collecting box through the dust collecting pipe.
[0017] 2. In the present invention, the second motor can be regarded as the driving source of the moving mechanism. The second motor can drive the first transmission rod to rotate along the first bearing block. The second motor can use a servo motor to drive the first transmission rod to rotate forward or backward. The first transmission rod can use a unidirectional screw. Since the surface of the first transmission rod is threadedly connected to the inner cavity of the transmission plate, when the first transmission rod rotates, it drives the moving mechanism to perform automatic displacement. The sliding seat on the top of the dust collection box can slide along the surface of the slide rail. The cooperation of the sliding seat and the slide rail further improves the stability of the displacement of the moving mechanism, realizes automatic grinding, and tries to avoid problems such as easy errors and low efficiency in manual grinding.
[0018] 3. In the present invention, a set of fixing structures are arranged on each placing table. The fixing structures can fix both sides of the skin raw material. One end of the second transmission rod is fixedly connected with a handle. By driving the handle, the second transmission rod can rotate along the second bearing block. The second transmission rod in the fixing structure can use a bidirectional screw. Two transmission blocks are relatively threadedly connected to one side of the second transmission rod. Therefore, when the second transmission rod rotates forward or backward, it drives the two transmission blocks to approach or move away from each other. When the two transmission blocks approach, they will push the connecting rods that are rotatably connected to each other to approach. The other ends of the two connecting rods will push the pressing plate to press down along the second connecting seat to press the skin raw material. Both sides of the pressing plate can slide along the connecting rod of the second bearing block to limit the position of the pressing plate. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Embodiment 1: Please refer to Figures 1 to 4 , the present invention provides a technical solution: A processing device for the leading edge skin of an aircraft wing, including a forming mechanism 1. The forming mechanism 1 includes a bottom plate 11. One side of the bottom plate 11 is fixedly connected with a placing table 12. The number of placing tables 12 is two. A hydraulic cylinder 13 is arranged between the two placing tables 12. The number of hydraulic cylinders 13 is multiple. One side of each hydraulic cylinder 13 is fixedly connected to one side of the bottom plate 11. The output end of the hydraulic cylinder 13 is fixedly connected with a forming die 14. A skin body 3 is arranged on the top of the placing table 12 and the surface of the forming die 14. One side of the bottom plate 11 is fixedly connected with a mounting frame 15. A moving mechanism 2 is arranged in the inner cavity of the mounting frame 15. The forming mechanism 1 is mainly used for pushing out and forming the skin body 3. Among them, the bottom plate 11 plays a main supporting role in the overall device. The two placing tables 12 can be used to support the skin raw material (the skin raw material can be made of aluminum alloy, titanium alloy or composite material, etc.). The middle part of the skin raw material is the forming part and is placed above the forming die 14. During forming, the forming die 14 can be lifted by multiple hydraulic cylinders 13. The forming die 14 is lifted and contacts the skin raw material. The forming die 14 continues to lift and stretch the skin raw material upward. The stretched skin raw material forms a skin body 3 with uniform thickness, which has a high degree of fit with the leading edge of the wing; The moving mechanism 2 includes a transmission plate 21. The surface of the transmission plate 21 is slidably connected to the inner cavity of the mounting frame 15. The transmission plate 21 is U-shaped. One side of the transmission plate 21 is fixedly connected to a moving frame 22. One side of the moving frame 22 is provided with a grinding unit 23. The grinding unit 23 is used for polishing the surface of the skin body 3. The grinding unit 23 includes mounting plates 2301. The number of the mounting plates 2301 is two. One sides of the mounting plates 2301 are fixedly connected to one side of the moving frame 22. A first transmission wheel 2302 is rotatably connected between the two mounting plates 2301. A first connecting seat 2303 is fixedly connected to one side of the moving frame 22. A second transmission wheel 2304 is rotatably connected to the inner cavity of the first connecting seat 2303. An adaptive frame 2305 is rotatably connected to one side of the moving frame 22. A third transmission wheel 2306 is rotatably connected to the inner cavity of the adaptive frame 2305. A grinding belt 2307 is drivingly connected to the surfaces of the first transmission wheel 2302, the second transmission wheel 2304 and the third transmission wheel 2306.

The output end of the first motor 2308 is coaxially and fixedly connected to one side of the first transmission wheel 2302. An extension plate 2309 is fixedly connected to one side of the moving frame 22. A spring 2310 is fixedly connected to one side of the extension plate 2309. The number of the springs 2310 is multiple. The other ends of the springs 2310 are fixedly connected to one side of the adaptive frame 2305. The moving mechanism 2 can reciprocate along the surface of the skin body 3. The surface of the skin body 3 is reciprocally ground by the grinding unit 23. The mounting frame 15 is fixedly connected to the bottom plate 11 integrally. The mounting frame 15 plays a main supporting role for the moving mechanism 2. The transmission plate 21 in the moving mechanism 2 is slidably connected to the chute on one side of the mounting frame 15, playing a main connecting role. The moving frame 22 can drive the grinding unit 23 to move. The grinding unit 23 is integrally connected to the moving frame 22 through the mounting plates 2301, the first connecting seat 2303 and the adaptive frame 2305. The first motor 2308 can drive the first transmission wheel 2302 to rotate. Since the first transmission wheel 2302, the second transmission wheel 2304 and the third transmission wheel 2306 are drivingly connected by the grinding belt 2307, the grinding belt 2307 drives the second transmission wheel 2304 and the third transmission wheel 2306 to rotate while rotating with the first transmission wheel 2302. The second transmission wheel 2304 and the third transmission wheel 2306 play a role in supporting the grinding belt 2307 and maintaining the tension. The adaptive frame 2305 elastically supported by the spring 2310 enables the grinding belt 2307 to be adaptively adjusted to fit the surface of the skin body 3 more closely; The moving mechanism 2 further includes a dust removal unit 24. The dust removal unit 24 is arranged on the top of the moving frame 22. The input ends of the dust removal unit 24 are arranged on both sides of the grinding unit 23. The dust removal unit 24 is used to collect the dust generated during the grinding process of the grinding unit 23. The input ends of the dust removal unit 24 are arranged on both sides of the grinding belt 2307, facilitating the suction of dust, aluminum powder, etc. generated during the grinding process, and improving the air quality in the grinding area.
[0023] As a further limitation of the dust removal unit 24 of the present invention, the dust removal unit 24 includes a dust collection box 2401. One side of the dust collection box 2401 is fixedly connected to the top of the moving frame 22. A fan 2402 is fixedly installed in the inner cavity of the dust collection box 2401. Dust collection pipes 2403 are fixedly communicated with both sides of the dust collection box 2401. The other ends of the dust collection pipes 2403 are fixedly communicated with a dust collection hood 2404. The dust collection hood 2404 is arranged on one side of the grinding belt 2307. The surface of the dust collection hood 2404 is fixedly connected to one side of the moving frame 22. The inner part of the dust collection box 2401 in the dust removal unit 24 is a cavity and is provided with a dust filter bag. The dust collection hood 2404 is communicated with the inner cavity of the dust collection box 2401 through the dust collection pipe 2403. The dust collection hood 2404 can be regarded as the input end of the dust removal unit 24 and is fixedly connected to both sides of the grinding belt 2307 through the moving frame 22. When the fan 2402 operates, a negative pressure is generated at the port of the dust collection hood 2404, sucking the dust generated when the grinding belt 2307 grinds the skin raw material. The dust is transported to the cavity dust filter bag of the dust collection box 2401 through the dust collection pipe 2403.
[0024] The specific implementation method of this embodiment is as follows: the staff places the skin raw material on the placement table 12 and fixes it, and lifts the forming mold 14 through multiple hydraulic cylinders 13. The forming mold 14 is lifted and contacts with the skin raw material. The forming mold 14 continues to lift and stretch the skin raw material upward. The stretched skin raw material forms a skin body 3 with uniform thickness, which has a high degree of fit with the leading edge of the wing. The moving mechanism 2 can also position the lifting height of the forming mold 14. When the forming mold 14 stretches the skin raw material to contact with the grinding belt 2307 in the grinding unit 23, the first motor 2308 can drive the first transmission wheel 2302 to rotate. Since the first transmission wheel 2302, the second transmission wheel 2304 and the third transmission wheel 2306 are connected by the grinding belt 2307, the grinding belt 2307 rotates with the first transmission wheel 2302. At the same time, it drives the second transmission wheel 2304 and the third transmission wheel 2306 to rotate. The second transmission wheel 2304 and the third transmission wheel 2306 support and maintain the tension of the grinding belt 2307. The adaptive frame 2305 elastically supported by the spring 2310 makes the grinding belt 2307 adaptively adjusted to fit the surface of the skin body 3 more closely. The moving mechanism 2 can reciprocate along the surface of the skin body 3, driving the grinding unit 23 to reciprocately grind the surface of the skin body 3. The dust hood 2404 can be regarded as the input end of the dust removal unit 24, and is fixedly connected to the two sides of the grinding belt 2307 through the moving frame 22. When the fan 2402 is in operation, the port of the dust hood 2404 generates negative pressure, and the dust generated when the grinding belt 2307 grinds the skin raw material is sucked in. The dust is transported to the cavity dust filter bag of the dust collecting box 2401 through the dust collecting pipe 2403.
[0025] Example 2: Please refer to Figures 1 - 5 The present invention provides a technical solution: a wing leading edge skin processing device for an aircraft. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A second motor 4 is fixedly installed on the top of a mounting frame 15. A first transmission rod 5 is fixedly connected to the output end of the second motor 4. A first bearing seat 6 is fixedly connected to the top of the mounting frame 15. The surface of the first transmission rod 5 is fixedly connected to the inner wall of the inner ring of the first bearing seat 6. The surface of the first transmission rod 5 is threadedly connected to the inner cavity of a transmission plate 21. The second motor 4 can be regarded as a driving source of a moving mechanism 2. The second motor 4 can drive the first transmission rod 5 to rotate along the first bearing seat 6. The second motor 4 can use a servo motor to drive the first transmission rod 5 to rotate forward or reverse. The first transmission rod 5 can use a one-way screw. Since the surface of the first transmission rod 5 is threadedly connected to the inner cavity of the transmission plate 21, when the first transmission rod 5 rotates, the transmission moving mechanism 2 is automatically displaced to achieve automated grinding, and avoid the problems of errors and low efficiency that are prone to manual grinding as much as possible.
[0026] As a further limitation of the slide rail 7 of the present invention, one side of the mounting frame 15 is fixedly connected to the slide rail 7, the surface of the slide rail 7 is slidably connected to a sliding seat 8, one side of the sliding seat 8 is fixedly connected to one side of the dust box 2401, and the moving mechanism 2 is automatically moved by the cooperation of the first transmission rod 5 and the transmission plate 21. When the moving mechanism 2 is displaced, the sliding seat 8 on the top of the dust box 2401 can slide along the surface of the slide rail 7, and the stability of the displacement of the moving mechanism 2 is further improved by the cooperation of the sliding seat 8 and the slide rail 7.
[0027] The specific implementation of this embodiment is as follows: the second motor 4 can be regarded as the driving source of the moving mechanism 2. The second motor 4 can be activated to drive the first transmission rod 5 to rotate along the first bearing seat 6. The second motor 4 can use a servo motor to drive the first transmission rod 5 to rotate forward or reverse. The first transmission rod 5 can use a one-way screw. Since the surface of the first transmission rod 5 is threadedly connected to the inner cavity of the transmission plate 21, when the first transmission rod 5 rotates, the transmission moving mechanism 2 is automatically displaced. The sliding seat 8 on the top of the dust box 2401 can slide along the surface of the slide rail 7. The cooperation between the sliding seat 8 and the slide rail 7 further improves the stability of the displacement of the moving mechanism 2, realizes automatic grinding, and avoids the problems of errors and low efficiency that are prone to manual grinding as much as possible.
[0028] Example 3: Please refer to Figures 1 - 6 The present invention provides a technical solution: a wing leading edge skin processing device for an aircraft. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A fixing structure 9 is provided on the top of the placement table 12. The fixing structure 9 is used to fix the position of the skin body 3. The fixing structure 9 can press and fix the skin raw material to ensure the firmness of the skin raw material during the stretching and forming process.
[0029] As a further limitation of the fixing structure 9 of the present invention, the fixing structure 9 includes a second bearing seat 91. One side of the second bearing seat 91 is fixedly connected to the top of the placing table 12. The inner wall of the inner ring of the second bearing seat 91 is fixedly connected with a second transmission rod 92. A transmission block 93 is threadedly connected to the surface of the second transmission rod 92. The number of the transmission blocks 93 is two. One side of each of the two transmission blocks 93 is rotatably connected with a connecting rod 94. The ends of the connecting rods 94 close to each other are rotatably connected. One side of the second bearing seat 91 is slidably connected with a pressing plate 95. One side of the pressing plate 95 is attached to one side of the skin body 3. The other side of the pressing plate 95 is fixedly connected with a second connecting seat 96. One end of the connecting rod 94 is rotatably connected to the inside of the second connecting seat 96. A set of fixing structures 9 is provided on each set of placing tables 12. The fixing structures 9 can fix both sides of the skin raw material. One end of the second transmission rod 92 is fixedly connected with a handle. By rotating the handle, the second transmission rod 92 can be driven to rotate along the second bearing seat 91. The second transmission rod 92 in the fixing structure 9 can adopt a bidirectional screw. The two groups of transmission blocks 93 are relatively threadedly connected to one side of the second transmission rod 92. Therefore, when the second transmission rod 92 rotates forward or reversely, the two groups of transmission blocks 93 move closer to or away from each other. When the two groups of transmission blocks 93 move closer, they will push the mutually rotatably connected connecting rods 94 closer. The other ends of the two groups of connecting rods 94 will push the pressing plate 95 downward along the second connecting seat 96 to press the skin raw material. Both sides of the pressing plate 95 can slide along the connecting rod of the second bearing seat 91 to limit the position of the pressing plate 95.
[0030] The specific implementation manner of this embodiment is as follows: After the staff places the skin raw material on the placing table 12, by rotating the handle, the second transmission rod 92 can be driven to rotate along the second bearing seat 91. The second transmission rod 92 in the fixing structure 9 can adopt a bidirectional screw. The two groups of transmission blocks 93 are relatively threadedly connected to one side of the second transmission rod 92. Therefore, when the second transmission rod 92 rotates forward or reversely, the two groups of transmission blocks 93 move closer to or away from each other. When the two groups of transmission blocks 93 move closer, they will push the mutually rotatably connected connecting rods 94 closer. The other ends of the two groups of connecting rods 94 will push the pressing plate 95 downward along the second connecting seat 96 to press the skin raw material.
