Description

Technical Field

[0001] This invention belongs to the technical field of wing assembly, and particularly relates to a wing assembly lifting and rotating bracket. Background Technology

[0002] To facilitate wing disassembly and segmented transportation, some wings are fitted with metal mating mounts to achieve docking between the wing and fuselage. The wing is assembled by bonding upper and lower skins with beams and ribs. The mating mounts are located on the end ribs of the wing. The installation accuracy of the end ribs and the positional accuracy of the mounting holes of the mating mounts directly affect the docking between the wing and the fuselage.

[0003] In aerospace wing assembly, multi-directional and multi-angle position adjustments of wing components are required. Existing wing assembly equipment has many limitations: some brackets only have a single lifting or rotating function, which cannot meet the position adjustment needs of complex assembly scenarios; there is a lack of effective limit and safety structures, which can easily lead to safety hazards such as automatic descent and overtravel; the mobility is insufficient, and the stability when fixed is poor, affecting assembly accuracy; when the wing is rotated to the vertical position, the center of gravity shift often causes operational difficulties and reduces assembly efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve at least one problem in the prior art by proposing a wing assembly lifting and rotating bracket.

[0005] To achieve the above objectives, the present invention proposes a wing assembly lifting and rotating bracket, comprising:

[0006] Base frame; A lifting mechanism is located on the base frame. The lifting mechanism includes a lifting plate and a lifting drive assembly. The lifting drive assembly is used to drive and control the height position of the lifting plate. The lifting plate is provided with limit blocks. A rotary drive mechanism includes a rotary reducer, a rotary shaft, and a rotary disk. The rotary reducer is mounted on a lifting plate and connected to the rotary shaft to drive the rotary shaft to rotate. The rotary disk is mounted on the outside of the rotary shaft and rotates synchronously with the rotary shaft. The rotary disk is provided with several limiting holes. After the rotary disk rotates to a predetermined angle position, it is fastened to the limiting block by a limiting member. A bracket is used to support the wing. The bracket is connected to the end of the rotating shaft. The height and rotation angle of the bracket are adjusted by the lifting mechanism and the rotation drive mechanism. The bracket is provided with clamping lugs for fastening to the wing.

[0007] As an optional implementation, the lifting plate has a groove in the middle, the rotary reducer is disposed in the groove, the lifting plate has bearing seats on both sides, the end of the rotating shaft passes through the bearing seat, and a bearing is installed inside the bearing seat and between the rotating shaft.

[0008] As an optional implementation, two lifting drive components are provided, each corresponding to one end of the lifting plate, and the two lifting drive components synchronously drive the lifting plate to move up and down.

[0009] As an optional implementation, the lifting drive assembly is a lifting push rod, and the movable end of the lifting push rod is connected to the lifting plate.

[0010] As an optional implementation, the lifting push rod can be a hydraulic push rod, a pneumatic push rod, or an electric push rod.

[0011] As an optional implementation, the lifting drive assembly includes a lifting reducer, a drive shaft, and a worm gear screw jack. The two output ends of the lifting reducer are respectively connected to one end of two drive shafts via couplings. The other end of the drive shaft is connected to the input end of the worm gear screw jack via a coupling. The output end of the worm gear screw jack is connected to the lifting plate.

[0012] As an optional implementation, the lifting mechanism further includes an upper limit member and a lower limit member, which are used to limit the upper limit movement position and the lower limit movement position of the lifting plate.

[0013] As an optional implementation, the bracket is provided with a counterweight for balancing the center of gravity of the wing.

[0014] As an optional implementation, the base frame is equipped with casters and a top-mounted brake, and the casters are equipped with a braking structure.

[0015] As an optional implementation, the limiting member is a limiting spring pin, a pin, or a bolt and nut structure.

[0016] The beneficial effects of this invention are as follows: By coordinating the lifting mechanism and the rotation drive mechanism, this invention enables the bracket to integrate rotation and lifting functions. When the bracket rotates to a predetermined angle, it achieves precise positioning through mutual limiting of the limiting component, limiting block, and rotating disk. Combined with the clamping lugs of the bracket, it is fixed to the wing, ensuring the stability of the bracket in wing assembly. The use of casters and a top-mounted brake on the base frame facilitates easy movement of the bracket and provides stable support. The addition of a counterweight to the bracket effectively balances the wing's center of gravity, ensuring stable and reliable wing assembly and reducing assembly difficulty. This wing assembly lifting and rotating bracket has a novel overall structure, is safe and convenient to operate, and helps improve wing assembly efficiency.

[0027] The present invention will now be described in detail with reference to the accompanying drawings.

[0028] See Figures 1 to 6 This embodiment provides a wing assembly lifting and rotating bracket, including: Base frame 1; The lifting mechanism is located on the base frame 1. The lifting mechanism includes a lifting plate 4 and a lifting drive assembly. The lifting drive assembly is used to drive and control the height position of the lifting plate 4. The lifting plate 4 is provided with a limit block 41 and a limit hole. The rotary drive mechanism includes a rotary reducer 2, a rotary shaft 21, and a rotary disk 5. The rotary reducer 2 is mounted on the lifting plate 4 and is connected to the rotary shaft 21 to drive the rotary shaft 21 to rotate. The rotary disk 5 is mounted on the outside of the rotary shaft 21 and rotates synchronously with the rotary shaft 21. The rotary disk 5 is provided with several limiting holes 51. After the rotary disk 5 rotates to a predetermined angle position, it is fastened to the limiting block 41 by the limiting member 6. The bracket 8 is used to support the wing. The end of the bracket 8 is connected to the rotating shaft 21 by a connecting plate and bolts. The height and rotation angle of the bracket 8 are adjusted by the lifting mechanism and the rotation drive mechanism. The bracket 8 is provided with clamping lugs 81 for fastening to the wing.

[0029] The base frame 1 includes a transverse support and a longitudinal support perpendicularly connected to the transverse support. Two longitudinal supports are provided, but other numbers such as three or four can also be used. When there are two longitudinal supports, they are arranged in parallel. Both the transverse and longitudinal supports are interconnected by several support columns. A mounting plate for installing the lifting drive assembly is provided on the longitudinal support. The rotating disk 5 is fixedly installed on the outside of the rotating shaft 21, and the rotating disk 5 is fixed to the rotating shaft by welding or keying. The clamping lug 81 and the rear connection point of the wing are connected by bolts to further ensure the stability during wing assembly. The rotary reducer 2 is fastened to the upper surface of the lifting plate 4 by mounting brackets and bolts. Multiple limiting holes 51 on the rotating disk 5 are arranged in a circular pattern. The number of limiting blocks and limiting components can be adjusted according to the positioning requirements of the rotating disk.

[0030] The base frame 1 is made of high-strength wear-resistant alloy material to improve the service life of the base frame and ensure structural strength.

[0031] The bracket 8 includes a left bracket, a right bracket, and a crossbeam. The left and right brackets are symmetrically arranged and connected by the crossbeam. Both the left and right brackets are connected by several pillars.

[0032] The left and right supports are in the shape of a convex character, a square shape, or other shapes with protruding structures. To improve the structure of the left and right supports, support corner plates can also be installed at the connection points of the support columns.

[0033] The upper surface of the bracket 8 can also be provided with a buffer structure, which can be a rubber pad with an anti-slip treatment. The buffer structure can prevent damage to the wing surface when the bracket supports the wing.

[0034] When using the wing assembly lifting and rotating bracket, first move the base frame 1 to the predetermined position for wing assembly and then fix it. The driving element of the lifting drive assembly drives the lifting plate 4 to the predetermined height position. The rotary reducer 2 of the rotary drive mechanism works, and its output end drives the rotating shaft 21 to rotate. The rotation of the rotating shaft drives the rotating disk 5 and the bracket 8 to rotate synchronously. When the bracket 8 rotates to the position where it is in contact with the wing surface, the limiting component positions the limiting block and the rotating disk to each other. The clamping lug 81 and the rear connection point of the wing are fastened with bolts, thus completing the fastening of the wing for subsequent assembly.

[0035] In this embodiment, refer to Figure 1 , Figure 3 and Figure 4 The lifting plate 4 has a groove in the middle, and the rotary reducer 2 is set in the groove of the lifting plate. The small gap between the rotary shaft 21 and the lifting plate 4 makes the overall structure more compact after the rotary reducer 5 is installed. The lifting plate 4 has bearing seats on both sides, and the end of the rotary shaft 21 passes through the bearing seat. The bearing seat and the rotary shaft 21 are fitted with bearings, which makes the rotary shaft 21 rotate more smoothly.

[0036] In this embodiment, two lifting drive components are provided, which correspond to the two ends of the lifting plate 4 respectively. The two lifting drive components drive the lifting plate 4 to move up and down synchronously. The dual-point lifting effect makes the up and down movement of the lifting plate 4 more stable.

[0037] Furthermore, the lifting drive component is a lifting push rod, and the movable end of the lifting push rod is connected to the lifting plate.

[0038] Furthermore, the lifting actuator can be a hydraulic actuator, a pneumatic actuator, or an electric actuator.

[0039] In other embodiments, see Figure 1 , Figure 3 and Figure 5The lifting drive assembly includes a lifting reducer 3, a drive shaft, and a worm gear screw jack 7. The two output ends of the lifting reducer 3 are connected to one end of each of the two drive shafts via couplings. The other end of each drive shaft is connected to the input end of the worm gear screw jack 7 via a coupling. The output end of the worm gear screw jack 7 is connected to a lifting plate 4. The worm gear screw jack 7 is a conventional structure. The output end of the worm gear screw jack 7 is a vertically movable screw 71. The upper end of the screw 71 is mounted on the lower end of the lifting plate 4 via a flange and bolts. The flange and the lifting plate 4 have threaded holes adapted to the external thread of the screw.

[0040] In this embodiment, the lifting mechanism further includes an upper limit component and a lower limit component. The upper limit component and the lower limit component are used to limit the upper limit movement position and the lower limit movement position of the lifting plate 4, so as to prevent the lifting mechanism from automatically descending and overtraveling, and reduce safety hazards.

[0041] In one embodiment of this invention, the upper limit plate and the lower limit plate are limit plates. The lower limit plate is fastened to the lower end of the screw 71 of the worm gear screw jack 7 with screws, and the upper limit plate is fastened to the flange with screws.

[0042] In other embodiments of this example, to improve the overall automation control of the bracket, a controller is installed on the base frame. The upper and lower limit switches are used to detect the upper and lower limit positions of the lifting plate, respectively. The limit switches transmit the detection signals to the controller, which outputs control signals to the power electrical components of the lifting drive assembly to achieve automated control of the lifting plate's height position. The controller is electrically connected to the rotary reducer to control its operation.

[0043] In this embodiment, refer to Figure 1 and Figure 6 The bracket 8 is equipped with counterweights 82 to balance the center of gravity of the wing, especially when the wing is placed vertically, to avoid operational difficulties caused by offset. The counterweights 82 are detachably mounted on the bracket 8 by bolts and nuts, making it easy to add or remove the number of counterweights 82 as needed.

[0044] In this embodiment, refer to Figure 1 and Figure 2 The base frame 1 is equipped with casters 11 and a top-mounted brake 12, with the casters 12 having a braking mechanism. The top-mounted brake 12 adopts an existing structure, is telescopic, and is fixedly supported after the base frame 1 is in a predetermined position. The casters 11 are provided to facilitate the movement of the base frame 1.

[0045] In this embodiment, the limiting member 6 is a limiting spring pin, a pin, or a bolt and nut structure, and the limiting member 6 is connected to the limiting hole 51.

[0046] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
