Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of large aircraft manufacturing, and particularly to an aircraft super panel inside-outside conversion method and device. BACKGROUND

[0002] In the field of large aircraft manufacturing, the aircraft super panel, as a core component constituting key parts such as the fuselage and the wing, directly affects the overall performance and production schedule of the aircraft. In order to ensure the shape accuracy of the super panel during assembly, an inside mold tooling and an outside mold tooling are usually used to position and support the inside and outside of the panel assembly, respectively. In the assembly process of the panel assembly, after the inside assembly is completed on the inside mold tooling, it needs to be transferred to the outside mold tooling for subsequent processing or assembly of the outside process. This process involves precise conversion between the inside mold tooling and the outside mold tooling.

[0003] At present, the inside-outside mold tooling conversion technology commonly used in the industry mainly relies on hoisting transfer: when the panel assembly completes the predetermined assembly process on the inside mold tooling, the outside mold tooling is hoisted by hoisting equipment such as a crane to directly above the inside mold tooling, and is placed on the support columns fixed around the inside mold tooling to realize positioning; then, the inside mold tooling starts the lifting mechanism to drive the panel assembly to rise to a set height matched with the outside mold tooling, thereby completing the transfer and positioning of the panel assembly from the inside mold tooling to the outside mold tooling, and realizing the conversion between the inside mold tooling and the outside mold tooling. However, the above existing conversion technology has many limitations in practical application, mainly in the following aspects: 1. Large occupied area: Since a set of support devices (such as support columns) needs to be separately arranged around each inside mold tooling to specially support the outside mold tooling, the installation space and operation space required by the overall tooling system are significantly increased, which easily causes low space utilization in the aircraft manufacturing workshop where production site resources are limited.

[0004] 2. Strict precision requirement of support devices: In order to meet the universal adaptation requirements of the same set of support devices to different specifications or models of outside mold tooling, the relative dimensional precision of the installation position and height of the support devices must be strictly controlled, which not only increases the processing and installation difficulty of the support devices, but also increases the debugging cost and period of the tooling system.

[0005] 3. Easy to cause product deformation: The inside mold tooling needs to directly bear the entire weight of the panel assembly and drive it to rise during the lifting process. Since the panel assembly usually has the characteristics of large size and relatively weak rigidity, it is easy to produce unintended deformation due to uneven stress or insufficient rigidity under the action of lifting force and the change of posture during the lifting process, thereby affecting the final assembly precision and product quality of the panel assembly.

[0006] In view of the above related art, the inventors believe that the prior art has the defects that the existing inner and outer forming tool conversion technology occupies a large area, the support device has poor adaptability, and the conversion precision and quality of the wallboard are easily affected. SUMMARY

[0007] To solve the above technical problems, the present application provides an aircraft super wallboard inner and outer conversion method and device.

[0008] The aircraft super wallboard inner and outer conversion method and device provided by the present application adopts the following technical scheme: The aircraft super wallboard inner and outer conversion device comprises an inner forming tool, a conversion assembly and an outer forming tool. The inner forming tool comprises two parallel tracks and a plurality of wallboard mounting racks arranged in the track mounting area. The conversion assembly is arranged in the transfer area of the track and outside the two tracks. The outer forming tool comprises a transfer fixing rack corresponding to the top of the conversion assembly and a plurality of wallboard transfer racks arranged below the transfer fixing rack.

[0009] By adopting the above technical scheme, the two parallel tracks are arranged in the inner forming tool, and the conversion assembly is integrated in the transfer area outside the track, replacing the support column structure surrounding the inner forming tool in the traditional technology. This modular layout does not need to reserve additional space for installing the support device on the periphery of the tool, so that the conversion area of the inner and outer forming tools is concentrated in the effective working range of the track extension, which can save 30%-50% of the ground occupation area compared with the prior art. The outer forming tool is precisely connected with the top of the conversion assembly through the transfer fixing rack, replacing the passive positioning mode in the traditional technology which depends on the consistency of the support column height. It is not necessary to accurately calibrate the position of the support column to the millimeter level, which shortens the tool installation and debugging time, and reduces the processing cost and installation difficulty of the support structure.

[0010] Preferably, the inner forming tool further comprises two inner forming racks connected to the two sides of the track respectively, and a limiting rod arranged on the side of the inner forming rack close to the transfer area. The two limiting rods are oppositely arranged, the wallboard mounting racks are arranged at intervals, and each wallboard mounting rack is fixedly connected to the inner forming rack.

[0011] By adopting the above technical scheme, the two inner forming racks are connected to the two sides of the track respectively, forming a symmetrical frame structure, and cooperating with the limiting rod arranged on the side of the inner forming rack close to the transfer area to construct a three-dimensional limiting system from the horizontal and vertical directions. The oppositely arranged limiting rods can not only limit the extreme position of the wallboard mounting rack in the transfer area to prevent it from leaving the track, but also can realize millimeter-level positioning calibration through precise cooperation with the conversion assembly or the outer forming tool during the transfer process of the wallboard assembly, so that the overall positioning accuracy of the wallboard assembly in the conversion process is improved, which is significantly better than the positioning effect of the traditional tool.

[0012] Preferably, the conversion assembly comprises two sets of symmetrically arranged conversion frames, each of which comprises a workbench, a fixed column arranged on both sides of the workbench, a control lifting platform arranged on the top of the fixed column, and a ball socket slidingly connected to the control lifting platform near the track, the ball socket is provided with a plurality of mounting holes along the circumference thereof, and a positioning column is arranged at the inner ring position of the ball socket, and a semispherical positioning hole is arranged at the top of the positioning column.

[0013] By adopting the above technical scheme, two sets of symmetrically arranged conversion frames are adopted, and the ball socket and the positioning column structure are matched to form a comprehensive precision positioning system. The plurality of mounting holes distributed along the circumference of the ball socket can be quickly locked with the transfer fixing frame of the external preservation tooling through the positioning pin, and the circumferential positioning in the horizontal direction is realized. The positioning column at the inner ring and the semispherical positioning hole at the top are matched with the transfer fixing frame of the external preservation tooling in a spherical manner. Even if there is a small angle deviation, the spherical surface can be self-adaptively adjusted. Compared with the traditional lifting conversion technology, the comprehensive positioning error of the wallboard assembly during the transfer process is greatly reduced, and the assembly precision of the aircraft super wallboard is effectively ensured.

[0014] Preferably, the control lifting platform comprises a lifting seat, a driving motor arranged on the top of the lifting seat, a lead screw connected to the output shaft of the driving motor through a transmission assembly, lifting slides arranged on both sides of the lifting seat, and a sliding block slidingly connected to the lifting slides and screwed with the lead screw, one side of the sliding block protrudes to form a mounting portion, and the ball socket is arranged on the mounting portion.

[0015] By adopting the above technical scheme, the control lifting platform adopts the structural design of the driving motor-lead screw transmission assembly. The high-precision characteristics of the lead screw transmission can greatly improve the precision of the lifting displacement. The lifting slides are symmetrically arranged on both sides of the lifting seat to provide stable guiding support for the sliding block. In combination with the linear transmission of the lead screw, the shaking or deviation caused by the lateral force during the lifting process is effectively avoided, so that the swinging amplitude of the ball socket during the lifting process is small. This high-precision and low-shaking lifting control ensures the precise butt joint of the external preservation tooling and the wallboard assembly in the vertical direction, and provides reliable guarantee for the overall positioning precision, which is especially suitable for the aircraft super wallboard manufacturing scene with extremely high assembly precision requirements.

[0016] Preferably, at least two limit switches are arranged on the inner wall of the lifting seat in the height direction at intervals, a detection rod is arranged on one side of the sliding block close to the inner wall of the lifting seat, and a detection surface corresponding to the limit switch is arranged on the detection rod.

[0017] By adopting the above technical scheme, at least two limit switches are arranged on the inner wall of the lifting seat along the height direction, and the detection rod and the detection surface on the sliding block are matched to build a double or even multiple safety protection mechanism; when the sliding block drives the ball socket to rise or fall, the detection surface on the detection rod moves with the sliding block, and once the limit switch is touched, the system triggers the emergency braking program immediately, and the driving motor stops running, effectively avoiding the overtravel phenomenon caused by the out-of-control sliding block.

[0018] Preferably, the transfer fixing frame comprises a frame body mounting portion and a butt joint portion arranged on both sides of the frame body mounting portion, each wall plate transfer frame is connected to the frame body mounting portion, each butt joint portion corresponds to each fixed column, and the bottom of the butt joint portion is provided with a rotating shaft corresponding to the positioning hole and a connecting hole corresponding to the mounting hole.

[0019] By adopting the above technical scheme, the modular design of the fixed portion and the plurality of butt joint portions is adopted, each butt joint portion corresponds to the fixed column of the conversion assembly, and through the cooperation of the rotating shaft at the bottom, the positioning hole and the mounting hole, the rapid and accurate butt joint of the external protection tooling and the conversion assembly is realized; the spherical cooperation of the rotating shaft and the hemispherical positioning hole allows automatic correction within a certain angle deviation, so that the butt joint process does not need to be repeatedly adjusted by manual, and only needs to align the butt joint portion with the fixed column, so that the preliminary positioning can be completed in a very short time.

[0020] Preferably, the shape of the wall plate transfer frame is consistent with the shape of the wall plate mounting frame, and the bottom of the wall plate transfer frame on both sides is provided with a clamping piece, the clamping piece is used for clamping a super wall plate on the corresponding wall plate mounting frame; the clamping piece comprises an adjusting plate arranged at the bottom of the wall plate transfer frame, a sliding groove arranged at the bottom of the adjusting plate, an L-shaped mounting plate slidingly connected in the sliding groove, two connecting plates fixedly connected to the mounting plate, drive plates rotatably connected to the two connecting plates respectively, drive rods connected to the ends of the two connecting plates, an adjusting rod arranged between the two connecting plates and rotatably connected to the drive plates and the connecting plates respectively, and a clamping rod connected to the adjusting rod, the clamping rod and the vertical plate of the mounting plate form a clamping space; the top of the adjusting rod is provided with an adjusting hole along the height direction thereof, the clamping rod is slidingly connected in the adjusting hole and is fixed by a nut.

[0021] By adopting the above technical scheme, when the clamping pieces of the wallboard transfer frame clamp the super wallboard on the wallboard mounting frame, the shape adaptability of the two can control the relative position deviation of the wallboard before and after the transfer within a small range, avoiding the misplacement or deformation of the wallboard caused by the mismatch of the tool shape. In addition, the clamping piece adopts the sliding adjustment structure of the adjusting plate-sliding groove-mounting plate, which cooperates with the linkage mechanism of the driving plate-driving rod-adjusting rod, so as to realize the flexible adjustment of the clamping space. By driving the driving plate to rotate through the driving rod, the adjusting rod moves between the connecting plates, thereby changing the distance between the clamping rod and the vertical plate of the mounting plate, so as to adapt to super wallboards of different thicknesses. The design of the adjusting hole at the top of the adjusting rod cooperates with the nut, allowing the clamping rod to be adjusted in the vertical direction, so that the clamping piece can adapt to the edge of the wallboard with a complex curved surface.

[0022] Preferably, the wallboard transfer frame comprises a fixed part and two rotating parts rotatably connected to the bottom of the fixed part, and the two clamping pieces are respectively arranged at the bottom of the two rotating parts; two opposite sides of the bottom of the fixed part are respectively provided with rotating plates, the upper ends of the two rotating plates are connected through a rotating shaft on one side and a pin shaft on the other side, the lower ends are fixed to the top of the rotating part, and the fixed part and the rotating part are respectively provided with overturning fixing holes, the two overturning fixing holes are aligned and fixed when the rotating part is overturned, and the bottom of the clamping plate of the rotating part is provided with a locking hole corresponding to the clamping of the wallboard; and a telescopic rod is rotatably connected to the fixed part through a mounting seat, the mounting seat is arranged corresponding to the rotating plate, and the bottom of the telescopic rod is rotatably connected to the position close to the bottom of the rotating plate.

[0023] By adopting the above technical scheme, through the rotatable connection design of the rotating part and the fixed part, the locking structure on the outer retaining frame and the clamping piece can be kept in the upward state before conversion, completely avoiding the space where the wallboard is located; after the wallboard is transferred to the specified position by the inner retaining tool, the rotating part drives the locking structure and the clamping piece to be synchronized downward, and the wallboard is precisely docked. This structure reduces the interference risk in the conversion process to zero, avoids equipment failure and product scrap caused by interference, and significantly improves the safety and success rate of the conversion operation.

[0024] Preferably, a pre-positioning assembly is arranged between the conversion assembly and the transfer fixture, and a detection and leveling assembly is arranged on the transfer fixture to detect whether the outer-maintained tooling is inclined and control the leveling of the rotating fixture when inclined, and at the same time control the pre-positioning assembly to stop positioning until the outer-maintained tooling is in a horizontal state; the pre-positioning assembly comprises a plurality of air pressure positioning pins arranged on the top of the mounting portion and uniformly distributed along the circumference of the ball socket, and a plurality of positioning holes arranged on the docking portion of the frame body and corresponding to each air pressure positioning pin one by one, and the inside of the positioning pin is integrated with a second pressure sensor; the detection and leveling assembly comprises leveling legs arranged around the bottom of the docking portion, a gravity pendulum arranged at the center of gravity position of the mounting portion of the frame body, and a trigger portion connected with the gravity pendulum through a connecting rod structure, and the air pressure positioning pin, the trigger portion and the pressure sensor are electrically connected with the controller.

[0025] By adopting the above technical scheme, through the cooperation of the air pressure positioning pins uniformly distributed along the circumference of the ball socket and the positioning holes on the docking portion of the frame body, preliminary accurate positioning between the conversion assembly and the transfer fixture can be achieved, installation errors are reduced, and a foundation is laid for subsequent accurate installation and docking; in addition, the inclination of the outer-maintained tooling is sensed by the gravity pendulum, which is transmitted to the trigger portion through the connecting rod structure, and then the leveling legs are controlled to level, and this leveling method based on the gravity principle can accurately detect the inclination state of the tooling and adjust in time to ensure that the outer-maintained tooling is in a horizontal state, avoiding installation errors caused by inclination.

[0026] The method for converting the inner and outer of the aircraft super panel comprises the following steps: S1: respectively mounting the super panel on each panel mounting rack, and then sliding to the transfer area through the track; S2: moving the outer-maintained tooling to the transfer area, and fixedly connecting the outer-maintained tooling with the top of the conversion assembly through the transfer fixture, and lowering the outer-maintained tooling by a predetermined distance by the conversion assembly, so that the panel transfer rack corresponds to the panel mounting rack one by one; S3: clamping the panel on the panel mounting rack by the panel transfer rack, and transferring the super panel to the panel transfer rack; S4: raising the outer-maintained tooling by the conversion assembly, and separating the transfer fixture from the top of the conversion assembly, and then transferring the outer-maintained tooling to the aircraft fuselage assembly area.

[0027] By adopting the technical scheme, track sliding and precise docking of the tool are adopted to replace the traditional hoisting transfer mode, the wallboard conversion time can be greatly shortened, and through modular and process operation, the difficulty and intensity of manual operation are significantly reduced; and the external maintenance tool is precisely docked with the top of the transfer fixing frame and the conversion assembly, replacing the passive positioning mode in the traditional technology which depends on the consistency of the support column height, without the need for millimeter-level precise calibration of the support column position, the tool installation and debugging time is shortened, and the processing cost and installation difficulty of the support structure are reduced.
