Description
Technical Field
[0001] This application relates to the technical field of aircraft manufacturing and maintenance, and in particular to a device for the internal and external conversion, vertical alignment and locking of an aircraft super panel. Background Technology
[0002] Aircraft super panels are core components in modern aircraft manufacturing. They are characterized by their large size, complex structure, and extremely high precision requirements, which directly affect the aerodynamic performance, structural strength, and assembly efficiency of the aircraft.
[0003] During the production, assembly, and maintenance of superfabricated panels, the panels need to undergo multiple attitude transformations, such as from horizontal to vertical placement, or from external processing to internal assembly. These transformations involve internal and external conversion, vertical alignment, and locking. The attitude transformation, alignment, and locking of aircraft superfabricated panels largely rely on traditional tooling or semi-automated equipment. Traditional methods of internal and external conversion of superfabricated panels are cumbersome, time-consuming, and pose a risk of collision. The locking devices also have poor reliability. Furthermore, the size and shape of superfabricated panels vary greatly among different aircraft models. Traditional tooling is often custom-designed and cannot flexibly adapt to various panel specifications.
[0004] Regarding the aforementioned technologies, the applicant believes that there is a deficiency in the flexibility of the super panel's internal and external conversion operation. Utility Model Content
[0005] To solve the above-mentioned technical problems, this application provides a device for the internal and external conversion, vertical alignment and locking of an aircraft super panel.
[0006] This application provides a device for the internal and external conversion, vertical alignment, and locking of an aircraft super panel, which adopts the following technical solution:
[0007] A device for converting and aligning the internal and external sides of an aircraft super panel, and for locking it, includes a conversion arm, a support arm, and a rotating connection device. One end of the rotating connection device is connected to the support arm, and the other end of the rotating connection device is connected to one end of the conversion arm. One end of the conversion arm is fixedly connected to the rotating connection device. The other end of the conversion arm is provided with a clamping and fixing mechanism, which includes a locking component and a mounting frame. One end of the mounting frame is bolted to the other end of the conversion arm, and the locking component is bolted to the other end of the mounting frame.
[0008] By adopting the above technical solution, the rotating connection device provides stable rotational support for the conversion arm, ensuring that the posture of the wall panel is controllable during the conversion process and avoiding positional deviation caused by shaking. The clamping and fixing mechanism is bolted to the conversion arm, and the locking component can quickly achieve rigid locking after the wall panel is aligned, further ensuring the stability of the super wall panel during the alignment process and avoiding the impact of loose parts on the alignment accuracy. It realizes the flexible conversion of the wall panel in the internal and external space states, and can adapt to the operation requirements of the wall panel in different positions without additional disassembly or adjustment of the overall device, reducing the auxiliary time when switching scenes.
[0009] Preferably, the connecting device includes multiple sets of connecting plates and a hinge device. One end of each set of connecting plates is respectively installed at both ends of the hinge device. The connecting plates and the hinge device are detachably connected. The hinge device is installed on the support arm and is detachably connected to the support arm. The other end of the multiple sets of connecting plates is fixedly connected to the conversion arm.
[0010] By adopting the above technical solution, the hinge device, as a connecting device, is connected to both the connecting plate and the support arm. The connecting plate is connected to the conversion arm, enabling the conversion arm and the support arm to rotate rotatably, thus providing a stable and smooth rotation function between the conversion arm and the support arm.
[0011] Preferably, the connecting plate is provided with a positioning pin that penetrates the connecting plate and the support arm on the other side of the mounting hinge device, and the positioning pin is detachably connected to multiple sets of connecting plates and support arms.
[0012] By adopting the above technical solution, the positioning pin passes through the connecting plate and the support arm, forming a composite connection structure of hinge rotation and rigid positioning pin limit. When the positioning pin is installed on the connecting plate and the support arm, the conversion arm and the wall panel are fixed on the inside. When the positioning pin is removed, the conversion arm rotates.
[0013] Preferably, a first pin plate is provided on one side of the support arm, and the first pin plate is fixedly connected to the support arm.
[0014] Preferably, one side of the conversion arm is provided with multiple sets of second pin plates, which are fixedly connected to the conversion arm.
[0015] By adopting the above technical solution, the rotation of the conversion plate causes the second pin plate on the conversion plate to rotate to the first pin plate. The positioning pin is installed on the first pin plate and the second pin plate, so that the conversion arm and the wall panel are fixed on the outside.
[0016] Preferably, multiple sets of auxiliary flipping devices are provided between the support arm and the rotating connection device. The multiple sets of auxiliary flipping devices are respectively installed on both sides of the support arm and the rotating connection device. One end of the auxiliary flipping device is fixedly connected to the support arm, and the other end of the auxiliary flipping device is rotatably connected to the rotating connection device.
[0017] Preferably, the auxiliary flipping device includes a rotating base, multiple sets of rotating hinges, and a telescopic rod.

[0018] By adopting the above technical solution, the two ends of the telescopic rod are connected to the rotating base and the connecting plate respectively through rotating hinges, so that the telescopic rod can be adjusted synchronously with the flipping angle during the extension and retraction process. The telescopic rod can provide controllable thrust or pull force for the conversion arm and the super wall panel held by the extension and retraction of the length, so as to realize the active attitude adjustment of the wall panel during the flipping and alignment process.
[0019] Preferably, the locking assembly includes a handle, a clamping block, a fixed locking frame, and a fixed mounting frame. The fixed mounting frame is connected to the mounting frame by bolts. One end of the handle is rotatably connected to the fixed locking frame. One end of the fixed locking frame is mounted on the fixed mounting frame. The fixed locking frame is rotatably connected to the fixed mounting frame. The clamping block is fixedly connected to the other end of the fixed locking frame. The middle part of the fixed locking frame is fixedly connected to the middle part of the handle.
[0020] By adopting the above technical solution, the handle and the middle part of the fixed locking frame are fixedly connected to form a lever structure. When the handle is turned, the fixed locking frame rotates around the connection point with the fixed mounting frame, which drives the clamping block to quickly press or release the wall panel. The rotation angle of the handle is directly related to the displacement of the clamping block. The locking state can be clearly judged by the position of the handle. The rotational connection between the fixed locking frame and the fixed mounting frame, and the fixed connection between the clamping block and the fixed locking frame, form a rigid transmission structure to ensure that the force of the handle can be efficiently transmitted to the clamping block and form a stable clamping force on the wall panel.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] The positioning pin passes through the connecting plate and the support arm, forming a composite connection structure of hinge rotation and rigid positioning pin limit. When the positioning pin is installed on the connecting plate and the support arm, the conversion arm and the wall panel are fixed on the inside. When the positioning pin is removed, the conversion arm rotates, and the conversion plate rotates, causing the second pin plate on the conversion plate to rotate to the first pin plate. The positioning pin is installed on the first pin plate and the second pin plate, fixing the conversion arm and the wall panel on the outside.
[0023] The handle is fixedly connected to the middle part of the fixed locking frame, forming a lever structure. When the handle is turned, the fixed locking frame rotates around the connection point with the fixed mounting frame, causing the clamping block to quickly press or release the wall panel. The rotation angle of the handle is directly related to the displacement of the clamping block. The locking state can be clearly judged by the position of the handle. The rotational connection between the fixed locking frame and the fixed mounting frame, and the fixed connection between the clamping block and the fixed locking frame, form a rigid transmission structure, ensuring that the force of the handle can be efficiently transmitted to the clamping block, forming a stable clamping force on the wall panel.

[0027] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0028] This application discloses a device for the internal and external conversion, vertical alignment, and locking of an aircraft super panel.
[0029] Reference Figure 1 and Figure 2The system includes a conversion arm 1, a support arm 2, and a rotating connection device 3. The rotating connection device 3 includes multiple sets of connecting plates 31 and a hinge device 32. Two sets of connecting plates 31 are respectively installed at both ends of the hinge device 32. The hinge device 32 is fixedly connected to one end of the support arm 2. The two sets of connecting plates 31 are rotatably connected to the support arm 2 through the hinge device 32. A positioning pin 33 is provided on the side of the connecting plate 31 away from the hinge device 32. The positioning pin 33 passes through the two sets of connecting plates 31 and the support arm 2. When the positioning pin 33 is inserted into the connecting plate 31 and the support arm 2, the connecting plate... 31 is fixed and cannot rotate relative to the support arm 2, so that the wall panel is fixed on the inner side. The other end of the connecting plate 31 is fixedly connected to the conversion arm 1. A first pin plate 21 is provided on one side of the support arm 2. The first pin plate 21 is fixedly connected to the support arm 2. Multiple sets of second pin plates 11 are provided on one side of the conversion arm 1. Two sets of second pin plates 11 are fixedly connected to the conversion arm 1. The conversion arm 1 rotates through the rotating connecting device 3, so that the second pin plate 11 coincides with the first pin plate 21. The positioning pin 33 is installed on the first pin plate 21 and the second pin plate 11, so that the wall panel is fixed on the outer side.
[0030] Two sets of auxiliary flipping devices 4 are provided on the support arm 2 and the two sets of connecting plates 31. The auxiliary flipping device 4 includes a rotating base 41, multiple sets of rotating hinges 42, and a telescopic rod 43. The rotating base 41 is fixedly connected to one side of the support arm 2. One end of the telescopic rod 43 is connected through a set of rotating hinges 42, and the other end of the telescopic rod 43 is connected to the connecting plate 31 through another set of rotating hinges 42. A clamping and fixing mechanism 5 is provided at the bottom of the conversion arm 1. The clamping and fixing mechanism 5 includes a locking component 51 and a mounting frame 52. Both ends of the mounting frame 52 are respectively connected to the locking component 51 and the bottom of the conversion arm 1 by bolts. 51 includes a handle 511, a clamping block 512, a fixing and locking frame 513, and a fixing and mounting frame 514. The fixing and mounting frame 514 is bolted to the mounting frame 52. The handle 511 and the fixing and locking frame 513 are cross-connected. One end of the fixing and locking frame 513 is rotatably connected to the bottom of the fixing and mounting frame 514. The clamping block 512 is installed on the other end of the fixing and locking frame 513. One end of the handle 511 is installed on one end of the fixing and mounting frame 514 and is rotatably connected to the fixing and mounting frame 514. When the handle 511 is rotated, it drives the fixing and locking frame 513 to rotate, causing the clamping block 512 to lock the wall panel.
[0031] The working principle of the aircraft super panel in this application for inward and outward conversion, vertical alignment and locking device is as follows: The conversion arm 1 is kept relatively stationary with the support arm 2 through the rotating connecting device 3, and the panel is in the inner position. The positioning pin 33 passes through the two sets of connecting plates 31 and the support arm 2. After insertion, it restricts the relative rotation between the connecting plates 31 and the support arm 2. The conversion arm 1 is fixedly connected to the other end of the connecting plate 31, and the conversion arm 1 cannot rotate, so that the panel is firmly fixed in the inner position. When the positioning pin 33 passing through the connecting plate 31 and the support arm 2 is pulled out, the connecting plate 31 and the support arm 2 can rotate. The hinge of the rotating connecting device 3 causes the connecting plate 31 to drive the conversion arm 1 to rotate relative to the support arm 2. In the conversion arm 1 rotation auxiliary flipping device 4, the rotating base 41 is fixed on the support arm 2. The two ends of the telescopic rod 43 are connected to the support arm 2 and the connecting plate 31 respectively through the rotating hinge 42. When the connecting plate 31 rotates, the telescopic rod 43 will extend and retract adaptively, and the angle can be adjusted by the rotating hinge 42 to provide for the flipping of the conversion arm 1. With auxiliary support and guidance, when the conversion arm 1 rotates to the outer position of the wall panel, the second pin plate 11 on the conversion arm 1 coincides with the first pin plate 21 on the support arm 2, achieving vertical alignment. The positioning pin 33 is installed on the overlapping first pin plate 21 and second pin plate 11. Through the limiting action of the positioning pin 33, the conversion arm 1 is prevented from rotating further, and the wall panel is fixed in the outer position. The locking assembly 51 is connected to the bottom of the conversion arm 1 via the mounting frame 52. When it is necessary to lock the wall panel, the handle is turned. 511, the handle 511 is rotatably connected to the fixed mounting bracket 514 and cross-connected to the fixed locking bracket 513. When the handle 511 is rotated, it will drive the fixed locking bracket 513 to rotate around the rotation point at the bottom of the fixed mounting bracket 514. The pressing block 512 at the other end of the fixed locking bracket 513 rotates with the fixed locking bracket 513, gradually approaching and pressing the wall panel. The wall panel is locked by the friction and pressure between the pressing block 512 and the wall panel, preventing the wall panel from loosening or shaking during operation.
[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
