Abstract
Description
Technical Field
[0001] This invention relates to the field of wing assembly tooling technology, and in particular to a wing body assembly tooling and its assembly method. Background Technology
[0002] The main wing assembly is an integrated manufacturing process that combines the core load-bearing structure and aerodynamic components of an aircraft wing. It is a crucial step in wing manufacturing, directly determining the wing's structural strength, aerodynamic precision, and overall flight safety. The assembly focuses on the main load-bearing spars, lateral support ribs, longitudinal reinforcing stringers, and external skin. Specialized precision tooling fixtures are used to accurately position, coordinate the relative positions of each component, and ensure rigid connections. The assembly process requires strict control over the wing surface curvature, component coaxiality, fit clearances, and geometric tolerances. Riveting, bolting, adhesive bonding, or composite connection techniques are employed to achieve a reliable connection between the internal frame and skin, while simultaneously eliminating assembly stress and ensuring uniform structural stress. The entire process relies on digital measurement and positioning technology to ensure a smooth and regular aerodynamic shape that meets aerodynamic requirements. This assembly stage connects parts processing with wing accessory installation and fuselage assembly; its quality directly affects the wing's fatigue life, aerodynamic efficiency, and flight stability. It is a critical assembly process in aviation manufacturing with high precision requirements and strict process specifications.
[0003] However, existing wing assembly fixtures mostly rely on conventional rigid clamping components to fix and position wing components in actual use. However, their structural design generally has obvious limitations and is difficult to effectively adapt to the complex curved shape of the wing. The wing skin and wing surface components are mostly continuous variable curvature hyperboloid structures with significant differences in curvature and tilt angle in different areas. Traditional clamping components mostly use planar or single rigid pressure head structures, which can only achieve line contact or local point contact with the curved surface. They cannot form a large-area uniform fit and support, which will not only cause uneven clamping force and local stress concentration, but also easily cause skin dents, deformation or surface scratches, which will damage the aerodynamic shape accuracy of the wing. At the same time, due to insufficient fit, components are prone to slippage, misalignment and shaking during assembly, resulting in positioning reference deviation and affecting the relative position accuracy of the spars, ribs and skin.
[0004] Therefore, a wing body assembly fixture and its assembly method are proposed to address the above problems. Summary of the Invention

As a further description of the above technical solution: The docking assembly includes a cylinder, one side of which is mounted on one side of the outer frame. A sliding plate is fixedly connected to the output end of the cylinder, and a mounting frame is fixedly connected to one side of the sliding plate. A hydraulic gripper is provided inside the mounting frame. As a further description of the above technical solution: The drive assembly includes a hydraulic cylinder, the bottom of which is mounted on the top of the outer frame, and a rotating plate is rotatably connected to the output end of the hydraulic cylinder. As a further description of the above technical solution: The clamping adaptation assembly includes a clamping frame, one of which is fixedly connected to the bottom of the rotating plate. A support plate is fixedly connected inside the support frame, and a fixed shaft is rotatably connected inside the support plate. The other clamping frame is fixedly connected to the outside of the fixed shaft. A squeezing roller is slidably connected inside the clamping frame. Sliding plates are fixedly connected to both sides of the squeezing roller. A disc spring is provided on the top of the sliding plates. A sliding groove is provided inside the clamping frame. As a further description of the above technical solution: The alarm assembly includes a guide frame, one side of which is fixedly connected to one side of the mounting frame. A sliding shaft is slidably connected inside the support frame. A return spring is sleeved on the outside of the sliding shaft. A fixing ring is fixedly connected to the outside of the sliding shaft. A docking plate is fixedly connected to one side of the sliding shaft. A pressing plate is fixedly connected to the other side of the sliding shaft. An alarm is installed inside the support frame. As a further description of the above technical solution: The top of the support frame is provided with an organic wing body, the bottom of the outer frame is fixedly connected with a support leg, and one side of the sliding plate is fixedly connected with a guide rod. As a further description of the above technical solution: The outer side of the second sliding plate is slidably connected to the inside of the slide groove, and the outer side of one of the clamping frames is rotatably connected to the inside of the support plate; As a further description of the above technical solution: The rack and the gear are meshed together, and the outside of the gear is in contact with the outside of the arc-shaped spring plate. As a further description of the above technical solution: The outer side of the extrusion triangle is slidably connected to the outer side of the fixed triangle, and the outer side of the cam is in contact with the outer side of one of the clamping frames; As a further description of the above technical solution: The specific method includes the following steps; S1. Preparation: First, the wing body can be placed on top of the support frame. Then, the hydraulic cylinder can be started to drive the rotating plate and the clamping frame to move downward. With the help of the rotation of the rotating plate and the adjustment of the squeezing rollers inside the clamping frame, the curvature design of the wing body can be adapted, thereby achieving the clamping and fixing of the wing body. S2. Docking Step: Then, the side wing part that is paired with the wing body can be placed inside the hydraulic gripper. The side wing part is fixed by the hydraulic gripper. Then, the cylinder can be activated to drive the sliding plate to move, which can then drive the side wing part to dock with the inside of the wing body. S3. Adjustment process: As the mounting frame moves, the guide frame moves, which in turn moves the rack, causing the gear to rotate. This causes the fixed triangular block and the pressing triangular block to press against each other, resulting in gear displacement. During displacement, the arc-shaped spring plate is pressed. When the fixed triangular block and the pressing triangular block no longer press against each other, the arc-shaped spring plate returns to its original position. This causes the cam to rotate and move, which in turn presses and shakes the clamping frame, allowing for adjustment and adaptation of the clamping of the wing body, resulting in more stable clamping. S4. Warning process: As the guide frame moves, it will squeeze the docking plate and cause it to move, which in turn will drive the sliding shaft to move. At this time, the fixed ring will compress the return spring, which will cause the squeezing plate to move. When the squeezing plate contacts the alarm, the alarm will sound, indicating that the docking is complete. If docking continues, it will squeeze the wing body and side wings, causing damage.
[0007] The present invention has the following beneficial effects: 1. In this invention, during the docking and assembly process, the mounting frame synchronously drives the guide frame to move, thereby causing the rack to slide and mesh with the gear to rotate. The inclined surface of the fixed triangular block and the pressing triangular block is used to drive the gear, the movable shaft and the end cam to generate axial displacement and press the arc-shaped spring plate. Then, the rebound force of the arc-shaped spring plate realizes the axial reset of the gear, the movable shaft and the cam. The cam completes the axial reciprocating action while rotating in the circumferential direction, thereby forming periodic pressing and small shaking on the clamping frame. It can dynamically adjust the clamping posture and clamping force of the clamping frame on the wing body in real time according to the stress changes generated during the docking process, effectively avoiding the wing offset problem caused by docking stress. It allows the tooling to maintain a stable clamping state on the wing body throughout the docking process, realizing the combination of adaptive clamping and dynamic stable clamping of the wing body from initial fixation to docking and assembly.

[0010] 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.
[0011] Reference Figure 1 , Figure 2 and Figure 6 This invention provides an embodiment of a wing body assembly fixture, comprising an outer frame 1. The outer frame 1 serves as the overall foundation and framework structure of the wing body assembly fixture, providing installation references and fixed supports for all functional components of the fixture. A docking assembly for assembly is provided on one side of the outer frame 1. The docking assembly includes a cylinder 2, one side of which is mounted on one side of the outer frame 1. The cylinder 2 is the power actuator of the docking assembly, ensuring the linear motion accuracy of the output end and preventing offset during wing docking due to installation deviations. A sliding plate 3 is fixedly connected to the output end of the cylinder 2. The mounting frame 4 is fixedly connected to the side. The main function of the sliding plate 3 is to stably transmit the linear power of the cylinder 2 to the mounting frame 4, ensuring the synchronous linear displacement of the mounting frame 4 and the hydraulic gripper 5. The mounting frame 4 is equipped with a hydraulic gripper 5, which is the side wing clamping actuator of the docking assembly. It is a high-precision, high-clamping-force hydraulic parallel gripper, which has the characteristics of adjustable clamping force, high clamping accuracy and stable operation. It can accurately adjust the size of the clamping opening according to the specifications and dimensions of the side wing component, so as to achieve a firm clamping of side wing components of different sizes and prevent the side wing from loosening or shifting during the docking process. Reference Figures 3 to 5The top of the outer frame 1 is equipped with a drive assembly for driving the clamping mechanism. The drive assembly includes a hydraulic cylinder 6, the bottom of which is mounted on the top of the outer frame 1. The hydraulic cylinder 6 is the core power actuator of the drive assembly, ensuring the vertical lifting accuracy of the output end. The output end of the hydraulic cylinder 6 is rotatably connected to a rotating plate 7. The core function of the rotating plate 7 is to adapt to the curvature angle of the wing body 31. When the hydraulic cylinder 6 drives the rotating plate 7 and the clamping frame 8 to move downward, the rotating plate 7 can automatically adjust the rotation angle according to the surface inclination angle of the wing body 31, so that the clamping frame 8 can... The wing body 31 is clamped to conform to its curved surface. A clamping adaptation component is located at the bottom of the drive assembly. This component includes clamping frames 8, one of which is fixedly connected to the bottom of the rotating plate 7. A support plate 10 is fixedly connected inside a support frame 9. The outside of one clamping frame 8 is rotatably connected to the inside of the support plate 10. A fixed shaft 11 is rotatably connected inside the support plate 10; the fixed shaft 11 is the rotational support shaft of the clamping adaptation component. The outside of the other clamping frame 8 is fixedly connected to the outside of the fixed shaft 11. The inside of the clamping frame 8... A slidable compression roller 12 is provided. The outer surface of the compression roller 12 is smoothed and covered with a soft, wear-resistant rubber layer. When the clamping frame 8 clamps the wing body 31, the outer surface of the compression roller 12 makes flexible contact with the surface of the wing body 31. This increases the contact area, ensures clamping stability, and avoids scratches and structural damage to the wing surface caused by hard contact. Sliding plates 13 are fixedly connected to both sides of the compression roller 12. The main function of the sliding plates 13 is to provide precise guidance for the up-and-down sliding of the compression roller 12. The top of the sliding plate 13... The part is equipped with a disc spring 14. The core function of the disc spring 14 is to provide elastic clamping force for the extrusion roller 12. When the clamping frame 8 clamps the wing body 31 downward, the extrusion roller 12 is pushed upward by the reaction force of the wing surface to push the sliding plate 13 and compress the disc spring 14. The clamping frame 8 has a groove 15 inside. The outside of the sliding plate 13 is slidably connected to the inside of the groove 15. The groove 15 strictly limits the lateral swing of the sliding plate 13, ensuring that the extrusion roller 12 always slides in the vertical direction, thereby achieving uniform clamping of the wing body 31. Reference Figure 3 , Figure 8 and Figure 9The outer frame 1 has a fixed internal support frame 9, which is the core structure for the tooling's wing support and internal component installation. Its top is a flat support surface, serving as the placement reference for the wing body 31. The support frame 9 contains a clamping adaptation component, and a warning component for indication is located on one side of the docking component. A rack 17 is slidably connected inside the support frame 9. The main function of the rack 17 is to convert the linear displacement of the guide frame 16 into the circumferential rotation of the gear 20. When the guide frame 16 moves with the mounting frame 4, it pushes the rack 17 to slide linearly along the inside of the support frame 9. A fixed frame 18 is fixedly connected to the bottom of the support frame 9. A movable shaft 19 is movably connected inside the fixed frame 18. The core function of the movable shaft 19 is to transmit the circumferential rotational power of the gear 20 to the cam 24. At the same time, it makes a synchronous axial displacement with the gear 20, so that the cam 24 can complete the axial reciprocating motion while rotating in the circumferential direction. The gear 20 is fixedly connected to the outside of the movable shaft 19. The rack 17 and the gear 20 are meshed. The main function of the gear 20 is to convert the linear motion of the rack 17 into its own circumferential rotation and drive the movable shaft 19 and the cam 24 to rotate synchronously. An arc-shaped spring plate 21 is fixedly connected inside the fixed frame 18. The outside of the gear 20 contacts the outside of the arc-shaped spring plate 21. The core function of the arc-shaped spring plate 21 is to provide axial return elastic force for the gear 20 and the movable shaft 19. When the gear 20 undergoes axial displacement under the squeezing action of the squeezing triangular block 23 and the fixed triangular block 22, the squeezing arc-shaped spring plate 21 undergoes elastic deformation, storing elastic potential energy. When the squeezing triangular block 23 is released from the squeezing state of the fixed triangular block 22, the arc-shaped spring plate 21 releases elastic potential energy, generating a rebound force, pushing the gear 20 and the movable shaft 19 to return axially, thereby driving the cam 24 to complete the axial reciprocating motion. A fixed triangular block 22 is fixedly connected to one side of the inside of the fixed frame 18, and a squeezing triangular block 23 is fixedly connected to one side of the outside of the gear 20. The outside of the squeezing triangular block 23 is slidably connected to the fixed frame 18. When the gear 20 drives the compression triangle 23 to rotate circumferentially, the inclined surface of the compression triangle 23 slides along the inclined surface of the fixed triangle 22. Through the guiding and compression action of the inclined surface, the gear 20 and the movable shaft 19 are pushed to generate axial displacement, which provides power for the axial reciprocating action of the cam 24. The cam 24 is fixedly connected to one side of the movable shaft 19. The outer side of the cam 24 is in contact with the outer side of one of the clamping frames 8. The core function of the cam 24 is to convert the circumferential rotation and axial reciprocating action of the movable shaft 19 into periodic compression and shaking of the clamping frame 8. When the movable shaft 19 drives the cam 24 to rotate circumferentially, the eccentric outer edge of the cam 24 forms a periodic compression force on the clamping frame 8. At the same time, the axial reciprocating action of the movable shaft 19 drives the cam 24 to move axially synchronously, further increasing the compression and shaking effect on the clamping frame 8. Reference Figures 7 to 9The warning component includes a guide frame 16. The core function of the guide frame 16 is to enable the linkage between the docking component, the clamping and adjusting component, and the warning component. One side of the guide frame 16 is fixedly connected to one side of the mounting frame 4. A sliding shaft 26 is slidably connected inside the support frame 9. The core function of the sliding shaft 26 is to transmit the extrusion force received by the docking plate 25 to the extrusion plate 29, and at the same time provide precise guidance for the displacement of the extrusion plate 29 and the fixing ring 28. A return spring 27 is sleeved on the outside of the sliding shaft 26. The main function of the return spring 27 is to provide return elasticity for the sliding shaft 26, the docking plate 25, and the extrusion plate 29. When the guide frame 16 extrudes the docking plate 25 and causes the sliding shaft 26 to move, the fixing ring 28 moves with the sliding shaft 26 and compresses the return spring. Spring 27 stores elastic potential energy. After docking is completed, cylinder 2 drives guide frame 16 to reset, the compressive force disappears, and the reset spring 27 releases elastic potential energy, pushing the fixed ring 28 and sliding shaft 26 to reset axially, so that the alarm component returns to its initial state and prepares for the next assembly operation. The external fixed connection of sliding shaft 26 is fixedly connected to fixed ring 28. The main function of fixed ring 28 is to provide a compressive force surface for reset spring 27. When sliding shaft 26 is displaced under the compression of guide frame 16, fixed ring 28 moves synchronously, forming a uniform compressive force on reset spring 27, ensuring that reset spring 27 deforms uniformly along the axial direction, and avoiding spring failure due to bias. A docking plate 25 is fixedly connected to one side of sliding shaft 26. Reference Figures 8 to 10 The docking plate 25 is the trigger force-bearing structure of the alarm component. Its main function is to receive the squeezing force of the guide frame 16 and transmit it to the sliding shaft 26 to trigger the subsequent action of the alarm component. The other side of the sliding shaft 26 is fixedly connected to the squeezing plate 29. The main function of the squeezing plate 29 is to trigger the alarm 30 to sound an alarm under the action of the sliding shaft 26 through contact squeezing with the alarm 30, indicating that the docking operation between the wing and the side wing is in place. The alarm 30 is installed inside the support frame 9. The alarm 30 is a contact-type sound and light alarm, which has the characteristics of fast response and obvious alarm signal. Its function is to simultaneously emit sound and light alarm signals under the contact squeezing of the squeezing plate 29, indicating to the operator that the side wing and the wing body 31 have been docked in place. The wing body 31 is installed on the top of the support frame 9, the bottom of the outer frame 1 is fixedly connected to the support leg 32, and the side of the sliding plate 3 is fixedly connected to the guide rod 33.
[0012] An assembly method for a wing body assembly fixture, the specific method including the following steps; S1. Preparation: First, the wing body 31 can be placed on top of the support frame 9. Then, the hydraulic cylinder 6 can be started to drive the rotating plate 7 and the clamping frame 8 to move downward. With the help of the rotation of the rotating plate 7 and the adjustment of the squeezing roller 12 inside the clamping frame 8, the curvature design of the wing body 31 can be adapted, thereby achieving the clamping and fixing of the wing body 31. S2. Docking Step: The side wing portion that is paired with the wing body 31 can then be placed inside the hydraulic gripper 5. The side wing portion is fixed by the hydraulic gripper 5. Then, the cylinder 2 can be activated to drive the sliding plate 3 to move, thereby driving the side wing portion to dock with the inside of the wing body 31. S3. Adjustment process: As the mounting frame 4 is displaced, the guide frame 16 is displaced, which in turn causes the rack 17 to be displaced, which in turn causes the gear 20 to rotate. At this time, the fixed triangular block 22 and the pressing triangular block 23 will press against each other, which will cause the gear 20 to be displaced. During the displacement, the arc spring plate 21 will be pressed. When the fixed triangular block 22 and the pressing triangular block 23 are no longer pressing, the arc spring plate 21 will be reset by means of its elasticity. At this time, the cam 24 will rotate and be displaced, which will then press and shake the clamping frame 8, thereby adjusting and adapting the clamping of the wing body 31, and thus making the clamping more stable. S4. Warning process: As the guide frame 16 moves, it will squeeze the docking plate 25 and cause it to move, which in turn will drive the sliding shaft 26 to move. At this time, the fixed ring 28 will compress the return spring 27, which will cause the squeezing plate 29 to move. When the squeezing plate 29 contacts the alarm 30, the alarm 30 will sound an alarm, indicating that the docking is complete. If docking continues, it will squeeze the wing body 31 and the side wings, causing damage.
[0013] Working principle: During operation, the hydraulic cylinder 6 of the drive assembly is first activated. The output of the hydraulic cylinder 6 drives the rotating plate 7 and the clamping frame 8 fixed below it downwards. This, in conjunction with another set of clamping frames 8 rotatably mounted on the support plate 10 within the support frame 9 via a fixed shaft 11, utilizes the rotational freedom of the rotating plate 7 to adapt to the curved surface angle of the wing body 31. Simultaneously, the squeezing roller 12 within the clamping frame 8, buffered by disc springs 14, adjusts to the curvature of the wing body 31 by sliding along the grooves 15 on both sides of the squeezing roller 12, thus achieving flexible clamping and fixation of the wing body 31. Then, the wing body 31 is... The side wing components are clamped and fixed by the hydraulic grippers 5 of the docking assembly. The starting cylinder 2 drives the sliding plate 3, mounting frame 4 and hydraulic grippers 5 at its output end to move as a whole towards the wing body 31, realizing the docking and assembly of the side wing and the wing body 31. During the docking process of the mounting frame 4, the guide frame 16 on its side moves synchronously, which drives the rack 17 in the support frame 9 to move synchronously. Through the meshing transmission between the rack 17 and the gear 20 on the movable shaft 19 in the fixed frame 18, the movable shaft 19 is driven to rotate. During the rotation of the gear 20, the pressing triangular block 23 on its side forms an oblique angle with the fixed triangular block 22 in the fixed frame 18. The surface compression engagement causes the gear 20, movable shaft 19, and end cam 24 to synchronously generate axial displacement and compress the arc-shaped spring plate 21 inside the fixed frame 18. When the compression triangle block 23 rotates with the gear 20 to disengage from the fixed triangle block 22, the rebound force of the arc-shaped spring plate 21 drives the gear 20, movable shaft 19, and cam 24 to axially reset, causing the cam 24 to generate axial reciprocating motion while rotating circumferentially. This, in turn, creates periodic compression and slight shaking on the clamping frame 8 inside the support frame 9, adjusting the clamping attitude and clamping force of the clamping frame 8 on the wing body 31 in real time, ensuring the wing body is properly clamped during docking. The stability and adaptability of clamping 31 prevent wing displacement caused by docking stress. On the other hand, during the feeding process, the guide frame 16 simultaneously squeezes the docking plate 25 of the alarm component, driving the sliding shaft 26 and the end squeezing plate 29 to overcome the elastic force of the return spring 27 and move axially along the support frame 9. When the squeezing plate 29 touches the alarm 30 in the support frame 9, the alarm is triggered immediately, indicating that the side wing and the wing body 31 are docked in place. At the same time, it avoids the excessive feeding of the cylinder 2, which may cause squeezing damage to the wing body 31 and the side wing components. This completes the entire assembly process of adaptive clamping, precise docking, dynamic stabilization and overshoot protection of the wing body.
[0014] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

Preparation: First, the wing body (31) can be placed on top of the support frame (9). Then, the hydraulic cylinder (6) can be started to drive the rotating plate (7) and the clamping frame (8) to move downward. With the help of the rotation of the rotating plate (7) and the adjustment of the squeezing roller (12) inside the clamping frame (8), the curvature design of the wing body (31) can be adapted, thereby achieving the clamping and fixing of the wing body (31). S2, docking steps: Then the side wing part that is paired with the wing body (31) can be placed inside the hydraulic gripper (5). The side wing part is fixed by the hydraulic gripper (5). Then the cylinder (2) can be started to drive the sliding plate (3) to move, and then the side wing part can be docked into the wing body (31). S3, Adjustment process: As the mounting frame (4) moves, the guide frame (16) moves, which in turn moves the rack (17), which in turn makes the gear (20) rotate. At this time, the fixed triangular block (22) and the squeezing triangular block (23) squeeze each other, which makes the gear (20) move. During the displacement, the arc spring plate (21) is squeezed. When the fixed triangular block (22) and the squeezing triangular block (23) no longer squeeze, the arc spring plate (21) is reset by means of its elasticity. At this time, the cam (24) rotates and moves, which in turn squeezes and shakes the clamping frame (8), thereby adjusting and adapting the clamping of the wing body (31), and making the clamping more stable. S4. Warning process: As the guide frame (16) moves, it will squeeze the docking plate (25) and cause it to move, which will then drive the sliding shaft (26) to move. At this time, the fixed ring (28) will compress the return spring (27), which will then cause the squeezing plate (29) to move. When the squeezing plate (29) contacts the alarm (30), the alarm (30) will sound an alarm. At this time, it means that the docking is completed. If docking continues, it will squeeze the wing body (31) and the side wings, causing damage.
