Description

Technical Field

[0001] This invention relates to the field of aircraft assembly and manufacturing technology, and in particular to a panel assembly device and assembly method. Background Technology

[0002] Composite materials are widely used in aviation, aerospace, and other fields due to their excellent properties such as lightweight, high strength, corrosion resistance, and fatigue resistance. Furthermore, with the development of composite material technology, their application ratio continues to increase. The fuselage panels of large aircraft are typically large, generally exceeding 5 meters in length, and some even reaching 20 meters. Due to the unique characteristics of the composite panel molding process, controlling their geometric dimensional accuracy is difficult. Therefore, the assembly of large-sized composite panels is one of the challenges in aircraft assembly.

[0003] While existing technologies offer assembly methods for composite wall panels, these methods all suffer from drawbacks in the resulting wall panel structures. Specifically, the main existing methods for assembling composite wall panels include rigid tooling assembly and DA (determinant assembly hole) assembly. The rigid tooling assembly method struggles to guarantee consistency between the frame components, leading to gaps between the frame components and the wall panels, necessitating more shims, increasing workload, assembly time, and costs. Furthermore, the DA hole assembly method results in lower positional accuracy of the frame surfaces, causing problems for subsequent panel assembly, such as misalignment and step discrepancies between the frames of different panels. Therefore, it is necessary to propose a wall panel assembly device and method to address the aforementioned problems in the existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a wall panel assembly device and assembly method to improve the problem of difficult wall panel assembly.

[0005] The panel assembly device includes a pre-assembly frame, a skin positioning frame, a drilling and riveting part, and a moving part. The pre-assembly frame and the skin positioning frame are used to position the components to be assembled, and the drilling and riveting part is used to drill and rivet the components to be assembled. The skin positioning frame is movably connected to the moving part so that the skin positioning frame moves along the moving part toward or away from the pre-assembly frame. The pre-assembly frame includes n sets of support frames. Each set of support frames includes a movable unit, a driving unit, and a positioning part. The movable unit and the driving unit are correspondingly connected. The driving unit is used to drive the movable unit to move, and the positioning part is disposed on the movable unit. Here, n is a positive integer.

[0006] The beneficial effects of the wall panel assembly device provided by the present invention are as follows: it can be used to realize the positioning, pre-connection and riveting of wall panel components, can adjust the distance between all skeleton parts and skin as a whole, and can also adjust the distance between different skeleton parts and skin individually after the overall adjustment, thereby ensuring the accuracy of the wall panel outline and the position accuracy of the frame stand surface, and can minimize the assembly gap to the greatest extent.

[0007] Furthermore, the assembly device also includes a pressure sensor, and the movable unit is connected to the pressure sensor. The pressure sensor is used to detect the magnitude of the force on the movable unit during the coupling process of the component to be assembled, so that the movable unit can be moved into place to ensure good contact between the skeleton part and the skin and to avoid overload during the assembly process.

[0008] The skin positioning frame includes an inner skin shape plate, a skin positioning component, and a skin fixing part; the skin positioning component is used to position the component to be assembled, and the skin fixing part is used to fix the component to be assembled on the inner skin shape plate.

[0009] The upper end of the skin positioning frame is provided with lifting lugs, which are used for lifting and transporting the skin positioning frame, making it easier to move the skin positioning frame during the assembly of the wall panel components.

[0010] The skin positioning frame is also equipped with a tooling interface, which is used to mate the skin positioning frame with the target position. This allows the skin positioning frame to be accurately positioned at the target position, facilitating operations such as pre-assembly, disassembly, deburring, and cleaning of the wall panel assembly.

[0011] Optionally, the skin fixing part includes multiple vacuum suction cups and / or multiple straps.

[0012] The driving method by which the driving unit drives the movable unit to move includes electric drive, hydraulic drive and pneumatic drive.

[0013] The present invention also provides a wall panel assembly method, wherein the wall panel is obtained by assembling the components to be assembled using the above-mentioned wall panel assembly device, wherein the components to be assembled include a frame and a skin, and the assembly method includes:

[0014] The frame is positioned using a pre-assembled frame;

[0015] The skin is positioned by the skin positioning frame, and the skin positioning frame together with the skin is moved to the pre-assembly frame by the moving part until the skin and the skeleton are aligned.

[0016] The drive unit drives the movable unit to move and position the skeleton and the skin relative to each other so that the skeleton and the skin fit together;

[0017] Pre-connection holes are made for the connection between the skeleton and the skin;

[0018] The movable unit, together with the skeleton, moves to separate the skeleton from the skin;

[0019] Perform deburring and cleaning operations;

[0020] Reattach the skin to the skeleton;

[0024] The driving unit driving the movable unit to move includes: n sets of drive units of the support frame driving the movable unit to move simultaneously, or a certain drive unit driving the movable unit to move alone.

[0025] Furthermore, the movable unit is connected to a pressure sensor; the driving unit driving the movable unit to move further includes: acquiring the force value detected by the pressure sensor, determining whether the force value reaches a preset threshold, and when the force value reaches the preset threshold, the driving unit stops driving the movable unit to move.

[0026] In summary, the wall panel assembly device and method of the present invention have the following beneficial effects: the wall panel assembly device can be used to realize the positioning, pre-connection, automatic drilling and riveting, and additional riveting of wall panel components, and can ensure the accuracy of the wall panel outline and the position accuracy of the frame stand surface, and can minimize the assembly gap, thus solving the problem of difficult assembly of large-size composite wall panels.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed following the word and its equivalents, but do not exclude other elements or objects.

[0039] To address the problems existing in the prior art, embodiments of the present invention provide a wall panel assembly device and assembly method for assembling wall panels.

[0040] Example 1

[0041] See the instruction manual appendix Figure 1 This embodiment provides a panel assembly device, including a pre-assembly frame 1, a skin positioning frame 2, and a moving part 3. Both the pre-assembly frame 1 and the skin positioning frame 2 are used for positioning the component to be assembled. The skin positioning frame 2 is movably connected to the moving part 3 so that the skin positioning frame 2 moves along the moving part 3 toward or away from the pre-assembly frame 1. The component to be assembled includes a frame 4 and a skin 5. The pre-assembly frame 1 is used for pre-positioning the frame 4, which includes a frame assembly 41, a connecting stringer 42, and a flat tail screw actuator joint assembly 43. The skin positioning frame 2 is used for positioning the skin 5.

[0042] See Figures 2-5 Specifically, the pre-assembled frame 1 includes n sets of support frames. Each set of support frames includes a movable unit 11, multiple drive units 12, and a positioning part 13. The movable unit 11 and the drive units 12 are connected to each other. The drive units 12 are used to drive the movable unit 11 to move. The positioning part 13 is disposed on the multiple movable units 11. Wherein, n is a positive integer.

[0043] In one possible embodiment, the positioning unit 13 includes multiple positioners, specifically including a frame positioner 131, a docking stringer positioner 132, and a tail screw actuator joint assembly positioner 133. The drive unit 12 drives the movable unit 11 to move, and can move along a preset direction when the skin positioning frame 2 moves to the mating position with the pre-assembled frame 1, thereby moving the skeleton 4 parts positioned on the movable unit 11, thereby realizing the contact and separation of the skin 5 and the skeleton 4 parts.

[0044] In some possible embodiments, the relative positional relationship between the movable unit 11 and the driving unit 12 can be as follows: Figure 3a and Figure 3b As shown. In a specific embodiment, under the drive of the drive unit 12, a set of support frames can be formed as follows. Figure 3a The status shown is adjusted as follows Figure 3b The state shown. In another specific embodiment, under the drive of the drive unit 12, a set of support frames can be formed as shown. Figure 3b The status shown is adjusted as follows Figure 3a The state shown. Among them, as... Figure 3a In the state shown, the distance between the movable unit 11 and the driving unit 12 is h1, as follows: Figure 3b In the state shown, the distance between the movable unit 11 and the driving unit 12 is h2, where h2 > h1.

[0045] The drive unit 12 can drive the movable unit 11 to move in various ways, including electric drive, hydraulic drive, pneumatic drive, and any drive method that can drive the movable unit 11 to move so that the frame 4, which is positioned on the movable unit 11 by the positioning part 13, can contact or separate from the skin 5. Since the wall panel may have various sizes, the specific number of movable units 11 and drive units 12 can be adapted to the size of the wall panel.

[0046] In one possible embodiment, among the multiple movable units 11, some movable units 11 are provided with frame locators 131, some movable units 11 are provided with docking stringer locators 132, and some movable units 11 are provided with flat-tail screw actuator joint assembly locators 133. A single movable unit 11 may be provided with one type of locator or multiple types of locators.

[0047] In one specific embodiment, a flat-tail screw actuator joint assembly locator 133 and a docking stringer locator 132 are simultaneously provided on some movable units 11, and a frame locator 131 and a docking stringer locator 132 are simultaneously provided on some movable units 11.

[0048] In one specific embodiment, the frame positioner 131 includes a positioning stop 134 and a positioning pin 135, wherein the positioning pin 135 can be fixed or detachable. The frame positioner 131 is used to position the frame assembly 41, thereby positioning the frame assembly 41 in such a way as... Figure 2 The position of the frame assembly 41 in the X and Z axes, as shown, allows it to move only in the Y axis direction to cooperate with the skin positioning frame 2 for positioning. The docking stringer 132 is used to position the docking stringer 42 in the following positions: Figure 2 The position of the docking stringer 42 in the X and Z axes, as shown, allows it to move only in the Y axis direction to cooperate with the skin positioning frame 2 for positioning. The flat-tail screw actuator joint assembly positioner 133 includes a main joint positioning pin 136, an end face positioning block 137, and an auxiliary support device 138, wherein the main joint positioning pin 136 is detachable. The flat-tail screw actuator joint assembly positioner 133 is used to position the flat-tail screw actuator joint assembly 43 to position the flat-tail screw actuator joint assembly 43 in the following positions: Figure 2 The position of the flat-tail screw actuator joint assembly 43 in the X and Y axes in the state shown allows it to rotate only along the Z axis. The rotational degree of freedom of the flat-tail screw actuator joint assembly 43 along the Z axis is constrained by the mating skin 5.

[0049] Furthermore, the movable unit 11 is connected to a pressure sensor 14, which is used to detect the magnitude of the force exerted on the movable unit 11 during the coupling process of the components to be assembled. Specifically, the force detected by the pressure sensor 14 is the magnitude of the force exerted on the movable unit 11 when the skin positioning frame 2 moves to the mating position with the pre-assembled frame 1, and the drive unit 12 drives the movable unit 11 to move so that the frame 4 fits against the skin 5. When the magnitude of the force detected by the pressure sensor 14 reaches a preset threshold, the movable unit 11 stops moving, thereby enabling the movable unit 11 to move into place so that the frame 4 and the skin 5 make good contact and avoid overload during the assembly process.

[0050] Optionally, the movement of the movable units 11 can be a collective movement of multiple movable units 11, or the movement of different movable units 11 individually. This allows for the overall adjustment of the distance between all parts of the skeleton 4 and the skin 5 support, or, after the overall adjustment, the individual adjustments of the distance between different parts of the skeleton 4 and the skin 5.

[0051] In one specific embodiment, the preset direction of movement of the movable unit 11 is as follows: Figure 2 The Y-axis direction in the state shown.

[0052] See the instruction manual appendix Figure 6 The skin positioning frame 2 includes an inner skin retaining plate 21, a skin positioning component 22, and a skin fixing part 23. The skin positioning component 22 is used to position the skin 5, and the skin fixing part 23 is used to fix the skin 5 to the inner skin retaining plate 21. There can be various methods for fixing the skin 5, and therefore the specific structure of the skin fixing part 23 can also vary. For example, the skin fixing part 23 can include multiple vacuum suction cups or multiple straps.

[0053] Since the size of the skin 5 may vary, the number of inner shaped clamping plates 21, the number of skin fixing parts 23, and the location of skin positioning parts can all be reasonably arranged according to the structure and size of the skin 5, and there are many possible specific arrangements.

[0054] In one possible embodiment, the skin positioning member 22 is provided in two locations, one as a main positioning member and the other as a secondary positioning member, with the two skin positioning members 22 located at both ends outside the skin 5 entity. The skin fixing part 23 includes multiple vacuum suction cups, which are disposed on the inner shaped clamping plate 21 of the skin.

[0055] In one possible embodiment, the skin positioning member 22 is positioned within the skin 5 entity. The skin fixing part 23 includes multiple vacuum suction cups and multiple straps, which are used simultaneously to fix the skin 5.

[0056] In one specific embodiment, the skin positioning element 22 is a skin positioning pin.

[0057] Furthermore, the upper end of the skin positioning frame 2 is provided with a lifting lug 24, which is used for lifting and transporting the skin positioning frame 2, making it more convenient to transfer the skin positioning frame 2 during the assembly of the wall panel components.

[0058] Preferably, the skin positioning frame 2 is also provided with a tooling interface (not shown in the figure). The tooling interface is located at the lower end of the skin positioning frame 2 and is used to mate the skin positioning frame 2 with the target position, so that the skin positioning frame 2 can be accurately positioned at the target position, which facilitates the pre-assembly, disassembly, deburring, cleaning and other operations of the wall panel assembly. The target position includes the drilling and riveting part 6, the riveting repair position and other positions where the skin positioning frame 2 needs to be moved during the wall panel assembly process for operation.

[0059] In some embodiments, the skin positioning frame 2 is further provided with an operating platform 25, which is used for operation by an operator. The operating platform 25 facilitates operation by the operator when operation is required during the assembly of the wall panel assembly.

[0060] In one specific embodiment, the skin positioning frame 2 further includes a support column 26 for supporting the skin positioning frame 2.

[0061] Furthermore, the panel assembly device also includes a drilling and riveting unit 6, which is used for automatic drilling and riveting of the panel components. The skin positioning frame 2 can be transferred to the drilling and riveting unit 6 to drill and rivet the panel components formed by connecting the skin 5 and the frame 4, which are fixed on the skin positioning frame 2. When the panel components are being processed in the drilling and riveting unit 6, the skin positioning frame 2 can serve as a support for the panel components and a support bracket for any remaining work after processing.

[0062] In one specific embodiment, the moving part 3 is a guide rail, and the skin positioning frame 2 is slidably connected to the guide rail.

[0063] In summary, the wall panel assembly device of this embodiment can be used to achieve positioning, pre-connection, automatic drilling and riveting, and additional riveting of wall panel components. It can also ensure the accuracy of the wall panel's outline and the positional accuracy of the frame stand surfaces, minimizing assembly gaps and solving the problem of difficult assembly of large-size composite wall panels. Using this assembly device for wall panel assembly offers advantages such as convenient operation, high flexibility, high assembly quality, and a high degree of automation.

[0064] Example 2

[0065] This embodiment provides an assembly method, which uses the wall panel assembly device as described in Embodiment 1 for assembly.

[0066] This assembly method uses the wall panel assembly device described in Example 1 to assemble the components to be assembled to obtain a large-size composite wall panel. The components to be assembled include a frame 4 and a skin 5. The specific implementation steps are as follows:

[0067] Move the movable unit 11 to the waiting position.

[0068] Position the frame 4 using the pre-assembled frame 1. The positioning result is as shown in the attached instruction manual. Figure 7 As shown. Specifically, it includes pre-positioning the frame assembly 41 using the frame locator 131 and fixing it with a clamp, pre-positioning the docking stringer 42 using the docking stringer locator 132, pre-positioning the flat-tail screw actuator joint assembly 43 using the flat-tail screw actuator joint assembly locator 133, and temporarily supporting it using the auxiliary support device 138.

[0069] The skin 5 is positioned by the skin positioning frame 2, and the skin positioning frame 2 together with the skin 5 is moved to the pre-assembly frame 1 by the moving part 3 until the skin 5 and the frame 4 are aligned.

[0070] Drive unit 12 drives movable unit 11 to move and position the skeleton 4 and skin 5 relative to each other so that the skeleton 4 and skin 5 fit together. The structure after fitting together is as shown in the attached instruction manual. Figure 8 As shown. Specifically, this includes first driving multiple movable units 11 in a coordinated manner, causing multiple drive units 12 to simultaneously drive multiple movable units 11 to move, thereby moving the entire frame 4 upwards until the pressure sensor 14 on one of the movable units 11 detects a threshold value. Then, individually driving the movable unit 11 whose pressure sensor 14 detection value has not reached the threshold value, until the pressure sensor 14 detection values ​​on multiple movable units 11 all reach the threshold value and the flat-tail screw actuator joint assembly positioner 133 reaches the assembly position and stops moving. Alternatively, first driving multiple movable units 11 in a coordinated manner, causing the entire frame 4 to move upwards until the flat-tail screw actuator joint assembly positioner 133 reaches the assembly position. Then, individually driving the other movable units 11, until the pressure sensor 14 detection values ​​on multiple movable units 11 all reach the threshold value and stops moving. At this point, the frame assembly 41, the docking girder 42, and the flat-tail screw actuator joint assembly 43 have all completed their final positioning.

[0071] Specifically, the process of the driving unit driving the movable unit to move, causing the movement to stop after the pressure sensor 14 on the movable unit 11 reaches a threshold, includes: acquiring the force value detected by the pressure sensor 14, determining whether the force value has reached a preset threshold, and when the force value reaches the preset threshold, the driving unit 12 stops driving the movable unit 11 to move.

[0072] In the above operation, driving multiple movable units 11 in a coordinated manner can prevent the docking girder 42 from tilting during tooling movement and causing damage to parts. Driving each movable unit 11 individually can independently adjust the gap between the frame 4 and the skin 5, so that the gap between the mating surfaces of the frame 4 and the skin 5 is minimized after the frame 4 is finally positioned. In the specific implementation process, when multiple movable units move simultaneously, movement stops when either the pressure sensor 14 on a certain movable unit 11 reaches the threshold or the flat-tail screw actuator joint assembly positioner 133 reaches the assembly position. Finally, the relative positioning of the frame 4 and the skin 5 is considered complete when the pressure sensor 14 on multiple movable units 11 all reach the threshold and the flat-tail screw actuator joint assembly positioner 133 reaches the assembly position.

[0073] Check the gap between the skin 5 and the skeleton 4, and apply shims to the gap as needed.

[0074] Pre-connection holes for connecting the skeleton 4 and the skin 5.

[0075] The movable unit 11, together with the skeleton 4, moves to the waiting position to separate the skeleton 4 from the skin 5.

[0076] Perform deburring and cleaning operations.

[0077] The skin 5 is reattached to the frame 4. Specifically, the operation of moving the skin positioning frame 2 together with the skin 5 through the moving part 3 to the pre-mounted frame 1 to the position where the skin 5 and the frame 4 are aligned, and the operation of driving the movable unit 11 driven by the drive unit 12 to move so as to position the frame 4 and the skin 5 relative to each other, so that the skin 5 and the frame 4 are reattached.

[0078] Temporary fasteners are installed in the pre-connection holes to connect the skin 5 to the frame 4, forming a temporary wall panel assembly.

[0079] Release the positioning between the frame 4 and the pre-assembled frame 1.

[0080] The temporary wall panel assembly is drilled, riveted, and further riveted to complete the wall panel assembly and obtain the wall panel. Specifically, this includes: transferring the skin positioning frame 2 and the temporary wall panel assembly to the drilling and riveting unit 6, and positioning the skin positioning frame 2 in the drilling and riveting unit 6. The temporary wall panel assembly is then automatically drilled and riveted to form the final connected wall panel assembly. The skin positioning frame 2 and the final connected wall panel assembly are then transferred to the riveting station, and positioned in the riveting station. The final connected wall panel assembly is then further riveted, and connectors and corner pieces are installed to complete the wall panel assembly assembly.

[0081] In one specific embodiment, the detailed steps for assembling wall panels using the wall panel assembly device described in Embodiment 1 include:

[0082] Move the movable unit 11 to the waiting position.

[0083] The frame 4 parts are positioned using the pre-assembled frame 1.

[0084] The skin 5 is positioned using the skin positioning frame 2, and then the skin positioning frame 2, together with the skin 5, is moved to the pre-assembly frame 1 via the moving part 3 until the skin 5 aligns with the frame 4. Specifically, this includes positioning the skin 5 using the skin positioning frame 2 and securing it with straps; moving the skin positioning frame 2, together with the skin 5, to the pre-assembly frame 1 via the moving part 3 until the skin 5 aligns with the frame 4; and connecting the air source and activating the vacuum suction cup to make the skin 5 tightly adhere to the inner mold plate.

[0085] The drive unit 12 drives the movable unit 11 to move so as to position the skeleton 4 relative to the skin 5.

[0086] Check the gap between the skin 5 and the skeleton 4, and apply shims as needed.

[0087] Approximately 20% of the pre-connection holes are made to connect the skin 5 to the skeleton 4.

[0088] The movable unit 11, together with the skeleton 4, moves to the waiting position to separate the skeleton 4 from the skin 5.

[0089] Disconnect the air supply to the vacuum suction cup and release the vacuum suction cup.

[0090] The skin positioning frame 2, together with the skin 5, moves to the riveting station via the moving part 3.

[0091] Perform deburring and cleaning operations.

[0092] Apply sealant to part 4 of the skeleton.

[0093] Reattach the skin 5 to the frame 4.

[0094] Temporary fasteners are installed in approximately 20% of the pre-connection holes to temporarily connect the skin 5 to the skeleton 4.

[0095] Remove the locating pin 135 on the frame 4 and loosen the clamp on the frame 4 to release the connection between the frame 4 and the pre-assembled frame 1.

[0096] Move the flat-tail screw actuator joint assembly positioner 133 to the waiting position to avoid interference and collision between the auxiliary support device 138 and the main joint during subsequent movement.

[0097] The panel assembly formed by temporarily connecting the skin positioning frame 2, the skin 5, and the frame 4 is moved a predetermined distance away from the pre-assembled frame 1 to avoid interference between the frame ribs and the frame locator 131 during the subsequent transfer of the panel assembly.

[0098] Using a hoisting device, the skin positioning frame 2, together with the temporarily connected wall panel assembly, is hoisted to the drilling and riveting section 6 via the lifting lug 24.

[0099] All movable units 11 of the pre-assembled frame 1 are returned to their waiting positions in preparation for the next assembly.

[0100] Move the support column 26, which is used to support the skin positioning frame 2, to the riveting station.

[0101] The skin positioning bracket 2 is positioned in the drilling and riveting part 6 through the tooling interface.

[0103] The skin positioning frame 2, together with the wall panel assembly, is hoisted from the automatic drilling and riveting station to the riveting repair station.

[0104] The skin positioning frame 2 is positioned in the riveting station through the tooling interface.

[0105] The wall panel assembly is then riveted and fitted with connectors and corner pieces to complete the assembly.

[0106] In summary, the wall panel assembly device and the assembly method using the wall panel assembly device of the present invention have the advantages of convenient operation, good flexibility, high assembly quality, and high degree of automation.
