Description

Technical Field

[0001] The invention belongs to the technical field of aircraft assembly, and in particular relates to aircraft lower wall panel assembly equipment. Background Art

[0002] During the domestic aircraft manufacturing process, especially during the modification of some aircraft, the aircraft panel components need to be assembled, removed from the frame, and hoisted. These processes are often accompanied by some problems.

[0003] A Chinese invention patent application, "Method and Tool for Unloading Aircraft Cargo Door Panel Assemblies," published with publication number "CN104309816," provides a tool for unloading aircraft cargo door panel assemblies. The tool uses a rope to unload and assemble a conformal tool along with the panel assembly attached to the tool. However, the following issues remain during the unloading and adjustment process:

[0004] The adjustment tool of the wall panel assembly is mainly used to adjust the length of the hanging rope connected to it. By changing the length of the hanging rope, the angle of the conformal tool is changed, and then the angle of the wall panel assembly is adjusted. Although this purpose can be achieved, the change in angle during the adjustment process still requires the staff's experience and judgment. In addition, since the entire equipment is in a suspended state during the adjustment process, the center of gravity will change, and someone needs to support it nearby, which is more inconvenient. Summary of the Invention

[0005] The purpose of the present invention is to provide an aircraft lower wall panel assembly equipment to solve the problem of inconvenience in angle control during the removal process of existing aircraft wall panel components.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is an aircraft lower wall panel assembly equipment, which includes a fixing frame, an adjusting seat, a counterweight seat and a rotating platform. The fixing frame is movably connected to the adjusting seat, the adjusting seat is fixedly connected to the counterweight seat, the counterweight seat is fixedly connected to the rotating platform, and the rotating platform is connected to a lifting device through a plurality of ropes.

[0008] Furthermore, the fixing frame includes a mounting plate, a fixing plate, a driving curved rod and a connecting plate. The two mounting plates are arranged parallel to each other, and the two ends of the two mounting plates are respectively connected by a fixing plate and a driving curved rod. The driving curved rod is a "C"-shaped rod structure, preferably an arc shape, to facilitate the subsequent calculation of the center of gravity, and the two driving curved rods are also arranged in parallel.

[0009] A fixed connection seat is installed on the surface of the protrusion of the driving crank arm, and a limiting sliding groove is provided on one side of the fixed connection seat. A movable connection seat is movably installed in the limiting sliding groove; when the movable connection seat moves in the limiting sliding groove, the distance between the movable connection seat and the fixed connection seat changes;

[0010] Furthermore, a number of fixings are provided at both ends of the connecting plate, and the connecting plate is fixedly connected to the wall panel assembly of the aircraft through the fixings. When the wall panel assembly of the aircraft is assembled, the connecting plate is connected and fixed to the assembled wall panel assembly through the fixings. The fixings can be selected according to the currently available solutions, and can be bolt type, clamp type, magnetic type, etc.

[0011] Furthermore, the adjustment seat includes an adjustment seat body, which is a box structure. The bottom surface of the adjustment seat body is provided with two mutually parallel slide grooves, and slide rails are installed on both sides of the slide grooves. A fixed assembly seat and a movable assembly seat are respectively installed in the slide rails. The fixed assembly seat is fixed to the end of one side of the slide rail, and the movable assembly seat slides in cooperation with the slide groove; the movable assembly seat slides in the slide groove, and the fixed assembly seat is fixed. When the movable assembly seat slides, the distance between it and the fixed assembly seat changes.

[0012] The fixed assembly seat is hinged to the fixed connecting seat, and the movable assembly seat is hinged to the movable connecting seat through the hinge between the two. When the movable assembly seat moves and the movable connecting seat moves, the hinge part can cause the driving bent rod to change its angle by rotating, and will not be damaged by tearing force; the top surfaces of the two movable assembly seats are welded with a driving plate, and the side surfaces of the driving plate are provided with threaded holes and sliding holes, and the two sliding holes are symmetrically arranged on both sides of the threaded hole, and the threaded holes are threadedly connected with threaded rods, and the threaded rods and the threaded holes cooperate with each other to form a screw structure, and a sliding rod is provided in the sliding hole; the self-locking characteristics of the screw structure itself can effectively maintain the posture of the driving bent rod without the need for an additional locking mechanism; by providing two additional sliding rods, the stability of the driving plate when being driven by the threaded rod is improved, and the problem of different stresses on the movable assembly seats on both sides of the driving plate caused by the center of gravity offset during rotation or movement, thereby reducing the service life, is prevented.

[0013] A sliding rod is hinged on the top surface of the driving plate.

[0014] Furthermore, one end of the threaded rod passes through the adjustment seat body and is connected to a driving device, which is an electric driving device or a manual driving device. The manual driving device is a crank, and the driving device mainly provides rotational force for the threaded rod.

[0015] Furthermore, the counterweight seat includes a counterweight seat body, which is a box structure, a limit hole is provided on the bottom surface of the counterweight seat body, a limit tube is installed in the limit hole, and the limit tube is rotatably matched with the limit hole; a limit arc seat is installed in the counterweight seat body, and the limit arc seat is an arc-shaped frame structure. The limit arc seat is preferably a detachable structure, and the space inside the limit arc seat is easily adjusted by arranging bolts and other structures at the joints, and the limit arc seat can be two parallel plywood with a gap, and the relative surfaces of the two plywood are provided with an arc-shaped groove with a semicircular cross-section; the limit arc seat can also be set to be surrounded by four arc-shaped metal strips. The cross-section of each of the two corresponding parts is a rectangular structure, and there is a groove between the four arc-shaped metal bars. A counterweight ball is provided in the limit arc seat, and the counterweight ball is arranged in the groove. The counterweight ball slides with the limit arc seat, and the surface of the counterweight ball is provided with a through-hole. The sliding rod passes through the limit tube and the counterweight ball in turn, and the sliding rod slides with the counterweight ball; when one end of the sliding rod is driven by the driving plate, due to the limitation of the limit tube, the other end of the sliding rod follows an arc trajectory in the counterweight seat. At this time, the counterweight ball that slides with the sliding rod is driven by the sliding rod, and due to the action of the limit arc seat, the counterweight ball can only make a circular arc movement in the limit arc seat.

[0016] Furthermore, the rotating platform includes a rotating seat and a mounting seat, the mounting seat is fixed to the outer upper surface of the counterweight seat body, the rotating seat and the mounting seat are both circular structures, the rotating seat and the mounting seat are mutually clamped, and the rotating seat and the mounting seat rotate in coordination; the top of the rotating seat is evenly arrayed with a number of hooks, which facilitate the entire equipment to be hung on the lifting equipment with ropes through the hooks.

[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention adds an adjustment seat and a counterweight seat to the device for fixing and lifting the aircraft wall panel. The adjustment seat is used to adjust the angle of the aircraft wall panel, and the counterweight seat is used to balance the center of gravity of the entire device during the angle adjustment process. The device is kept in a relatively stable state for angle adjustment as much as possible, which reduces the difficulty of adjustment, prevents deformation of the surface or punching position of the aircraft wall panel due to excessive swinging angle, and improves the yield rate in the aircraft production process.

[0019] 2. The present invention divides the angle adjustment of the aircraft wall panel into horizontal angle adjustment and vertical angle adjustment by providing an adjustment seat and a rotating table. By decomposing the adjustment angle, the difficulty of adjusting the angle of the aircraft wall panel is further reduced and the work efficiency is improved.

[0033] Example 1:

[0034] See also Figure 1-Figure 7 As shown, this embodiment is a technical solution using the crank as the driving device:

[0035] The present invention is an aircraft lower wall panel assembly equipment, which includes a fixing frame 1, an adjusting seat 2, a counterweight seat 3 and a rotating platform 4.

[0036] The fixing frame 1 includes a mounting plate 101, a fixing plate 102, a driving curved rod 103, and a connecting plate 104. The two mounting plates 101 are arranged parallel to each other, and the two ends of the two mounting plates 101 are connected by a fixing plate 102 and a driving curved rod 103 respectively. The driving curved rod 103 is a "C"-shaped rod structure, preferably an arc shape, to facilitate the subsequent calculation of the center of gravity, and the two driving curved rods 103 are also arranged in parallel.

[0037] A fixed connection seat 105 is mounted on the surface of the protrusion of the driving curved rod 103. A limiting slot is provided on one side of the fixed connection seat 105. A movable connection seat 106 is movably mounted in the limiting slot. When the movable connection seat 106 moves in the limiting slot, the distance between the movable connection seat 106 and the fixed connection seat 105 changes.

[0038] Among them, several fixing parts are provided at both ends of the connecting plate 104, and the connecting plate 104 is fixedly connected to the wall panel assembly of the aircraft through the fixing parts. When the wall panel assembly of the aircraft is assembled, it is connected and fixed to the assembled wall panel assembly through the fixing parts. The fixing parts can be selected according to the currently available solutions, and can be bolt type, clamp type, magnetic type, etc.

[0039] Among them, the adjustment seat 2 includes an adjustment seat body 201, the adjustment seat body 201 is a box structure, and the bottom surface of the adjustment seat body 201 is provided with two mutually parallel slide grooves, and slide rails 202 are installed on both sides of the slide grooves. A fixed assembly seat 203 and a movable assembly seat 204 are respectively installed in the slide rails 202. The fixed assembly seat 203 is fixed at the end of one side of the slide rail 202, and the movable assembly seat 204 slides with the slide groove; the movable assembly seat 204 slides in the slide groove, and the fixed assembly seat 203 is fixed. When the movable assembly seat 204 slides, the distance between it and the fixed assembly seat 203 changes.

[0040] The fixed assembly seat 203 is hinged to the fixed connecting seat 105, and the movable assembly seat 204 is hinged to the movable connecting seat 106. Through the hinge between the two, when the movable assembly seat 204 moves and drives the movable connecting seat 106 to move, the hinged part can cause the driving crank 103 to change its angle by rotating, and will not be damaged by the tearing force; the top surfaces of the two movable assembly seats 204 are welded with a driving plate 205, and the side surfaces of the driving plate 205 are provided with threaded holes and sliding holes. The two sliding holes are symmetrically arranged on both sides of the threaded holes, and the threads in the threaded holes are connected to screws. The threaded rod 206 and the threaded hole cooperate with each other to form a screw structure, and a sliding rod 207 is provided in the sliding hole; through the self-locking characteristics of the screw structure itself, the posture of the driving curved rod 103 can be effectively maintained without the need for an additional locking mechanism; by providing two additional sliding rods 207, the stability of the driving plate 205 when driven by the threaded rod 206 is improved, and the problem of different stresses on the movable assembly seats 204 on both sides of the driving plate 205 caused by the center of gravity shift during rotation or movement is prevented, thereby preventing the problem of reduced service life.

[0041] A sliding rod 208 is hinged on the top surface of the driving plate 205 .

[0042] One end of the threaded rod 206 passes through the adjustment seat body 201 and is connected to a driving device, which is a crank 209 . The driving device mainly provides rotational force for the threaded rod 206 .

[0043] Among them, the counterweight seat 3 includes a counterweight seat body 301, which is a box structure. A limiting hole 302 is set on the bottom surface of the counterweight seat body 301, and a limiting tube 305 is installed in the limiting hole 302. The limiting tube 305 rotates with the limiting hole 302; a limiting arc seat 303 is installed in the counterweight seat body 301, and the limiting arc seat 303 is an arc-shaped frame structure. The limiting arc seat 303 is preferably a detachable structure, and the space inside the limiting arc seat 303 is easily adjusted by setting bolts and other structures at the joints. The limiting arc seat 303 can be two parallel plywood with a gap, and the relative surfaces of the two plywood are provided with an arc-shaped groove with a semicircular cross-section; the limiting arc seat 303 can also be set to a cross-section surrounded by four arc metal strips, each corresponding to the other. The balancing ball 304 is arranged in the limit arc seat 303, and the balancing ball 304 is arranged in the groove. The balancing ball 304 slides with the limit arc seat 303, and the surface of the balancing ball 304 is provided with a through hole. The slide bar 208 passes through the limit tube 305 and the balancing ball 304 in turn, and the slide bar 208 slides with the balancing ball 304; when one end of the slide bar 208 is driven by the driving plate 205, due to the limitation of the limit tube 305, the other end of the slide bar 208 follows an arc trajectory in the balancing weight seat 3. At this time, the balancing ball 304 that slides with the slide bar 208 is driven by the slide bar 208, and due to the action of the limit arc seat 303, the balancing ball 304 can only make a circular motion in the limit arc seat 303.

[0044] Among them, the rotating platform 4 includes a rotating seat 401 and a mounting seat 402. The mounting seat 402 is fixed on the outer upper surface of the counterweight seat body 301. The rotating seat 401 and the mounting seat 402 are both circular structures. The rotating seat 401 and the mounting seat 402 are mutually clamped, and the rotating seat 401 and the mounting seat 402 rotate in coordination; the top of the rotating seat 401 is evenly arrayed with several hooks in a circular array, and the hooks facilitate the entire equipment to be hung on the lifting equipment with ropes.

[0045] It should be further explained that a spirit level is provided on the fixing plate 102; a degree scale is provided on the surface of the rotating seat 401, and a pointer is provided on one side of the mounting seat 402; this is convenient for measuring degrees and provides a reference for adjusting the angle of the aircraft wall panel.

[0046] The fixing member is preferably a bolt type, and the lifting device is preferably a crane. The aircraft lower wall panel assembly equipment of this embodiment is suspended by a rope. The specific method of use of this embodiment is as follows: after the aircraft wall panel is assembled on the assembly rack, the lower wall panel assembly equipment of the present invention is fixed to the above-mentioned aircraft wall panel by the fixing member, and then the crane is started to lift the aircraft wall panel through the lower wall panel assembly equipment;

[0047] At this time, the aircraft panel is limited by the fixed angle of the connecting plate 104, and the angle of the aircraft panel needs to be further adjusted. The adjustment method is as follows:

[0048] First, according to the angle required for the aircraft wall panel in the subsequent process, the placement angle of the aircraft wall panel is adjusted by rotating the crank 209; when the crank 209 is rotated, the crank 209 drives the threaded rod 206 to rotate, and the threaded rod 206 then drives the drive plate 205 to slide on the sliding rod 207 through the screw structure formed with the drive plate 205. The direction of rotation is preferably that when the crank 209 is rotated clockwise, the movable assembly seat 204 is away from the fixed assembly seat 203, and when the crank 209 is rotated counterclockwise, the movable assembly seat 204 is close to the fixed assembly seat 203; usually, the assembled aircraft wall panel is at a relatively vertical angle, so the movable assembly seat 204 is close to the fixed assembly seat The distance between the seats 203 is also relatively close. At this time, the movable assembly seat 204 is gradually pushed to a position away from the fixed assembly seat 203 by rotating the crank handle 209 clockwise; the movable assembly seat 204 drives the movable connection seat 106 to move, thereby changing the angle of the driving crank rod 103; when the angle of the driving crank rod 103 changes, the center of gravity of the entire assembly equipment composed of the aircraft wall panel and the lower wall panel changes, causing the entire angle to tilt. At this time, due to the limitation of the limiting tube 305, during the movement of the driving plate 205, the part of the sliding rod 208 in the counterweight seat 3 moves in the opposite direction, and the counterweight ball 304 installed thereon also moves in the opposite direction in a circular arc;

[0049] The driving curved rod 103 is preferably an arc-shaped structure, so that the change in the distance between the movable assembly seat 204 and the fixed assembly seat 203 is actually the change in the chord of the driving curved rod 103, and the relationship between the two should satisfy the trigonometric function relationship. The structure formed by the sliding rod 208 and the limiting tube 305 is a similar triangle, so the two ends of the sliding rod 208 should constitute a proportional relationship, and the counterweight ball 304 is only related to the inclination angle of the sliding rod 208, so the counterweight ball 304 and the sliding rod 208 satisfy the trigonometric function relationship. In summary, by selecting a counterweight ball 304 with appropriate weight, the problem of center of gravity offset when the angle of the aircraft wall panel changes can be balanced more accurately; the stability of the equipment operation is improved, and the horizontal angle of the aircraft wall panel can be adjusted by the rotating table 4.

The power supply can select a wired power supply such as AC power, or an independent power supply such as a battery, lithium battery, etc. according to needs; the control module can select wired control or wireless control. Wireless control requires a signal receiver and a signal transmitter. The signal receiver is used to receive the motor control signal transmitted by the signal transmitter.
