[0002] Aircraft wing repair is a crucial aspect of aircraft maintenance. During aircraft modification or repair, wing maintenance is necessary. The wing includes components of varying sizes and types, such as the elevator, rudder trim tabs, and spare elevator trim tabs. Although the components differ, their overall internal structures are similar. For example, the elevator trim tabs are located between ribs 1 to 10 at the rear of the elevator. Their installation location on the aircraft is shown in [the image / document / reference needed]. Figure 1 Item 3, the elevator trimmer, is suspended from the elevator by three trimmer suspension brackets. It is a detachable component, with one on each side, for a total of two per unit. The elevator trimmer is a fully enclosed structure consisting of two wing skin panels, 11 ribs, six leading ribs, four beams, three joints, and six bulkheads. The three suspension brackets are mounted on the three joints and enclosed within the trimmer. The upper and lower wing skin panels, ribs, leading ribs, beams, and bulkheads are all made of three-dimensional woven 3D felt composite material. The joints are made of aluminum alloy. Six counterweights are installed on both sides of the suspension brackets in the leading edge area of ​​the skin. Ten Ф6 mm drainage holes are opened on the lower wing skin. The outer surface of the trimmer's trailing edge is covered with three layers of high-strength SW-100 fiberglass cloth, and the trailing and leading edges are filled with H1-3 epoxy resin and fiberglass.

[0035] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0036] See Figure 2-8 An auxiliary flipping fixture for aircraft wing repair includes a first frame structure 1 and a second frame structure 4 for moving the entire flipping fixture. Clamping plates 2 are symmetrically fixed to the first frame structure 1 and the second frame structure 4, and the clamping plates 2 are fixedly connected to each other via a telescopic beam assembly 9. A rotating mechanism 5 is rotatably mounted on the top of the first frame structure 1 and the second frame structure 4, respectively. A flipping frame 6 for clamping and supporting the wing is mounted at the output end of the rotating mechanism 5. A locking gear ring 7 is fixed on the rotating mechanism 5, and the locking gear ring 7 cooperates with a foot-operated locking mechanism 3, which is fixed to the corresponding first frame structure 1 and the second frame structure 4. This flipping fixture can be used for clamping and fixing the wing during aircraft wing repair, and facilitates the flipping and adjustment of the wing during the repair process, thereby adjusting its angle and improving the efficiency and quality of the entire repair process. In practical use, firstly, according to the length of the corresponding model of the wing, adjust the telescopic beam assembly 9, and then adjust the distance between the first frame structure 1 and the second frame structure 4. Then, fix the corresponding wing between the tilting frame 6. Then, rotate the rotating mechanism 5 according to the required angle. The rotating mechanism 5 drives the tilting frame 6, and then the tilting frame 6 drives the wing to rotate at the corresponding angle. After the angle adjustment is completed, the foot locking mechanism 3 cooperates with the locking gear ring 7 to lock the position, so as to facilitate the corresponding maintenance work on the wing.

[0037] Furthermore, the first frame structure 1 and the second frame structure 4 adopt the same structure; the first frame structure 1 includes a frame base 102, with self-locking casters 101 installed at the four corners of the bottom end of the frame base 102, and a gantry frame 104 fixed to the top of the frame base 102. A rotating mechanism 5 is rotatably installed at the middle of the top end of the gantry frame 104. By adopting the above-mentioned first frame structure 1 and second frame structure 4, it is convenient to move the entire tilting fixture subsequently, thereby facilitating the movement of the tilting fixture during use and enhancing the flexibility of use. Moreover, the above structure ensures the stability and reliability of the frame structure.

[0038] Furthermore, a diagonal brace 103 is fixed between the gantry frame 104 and the frame base 102, and an inner support rod 105 is fixed at the inner top corner of the gantry frame 104. The diagonal brace 103 enhances the stability of the fixed installation of the gantry frame 104. The inner support rod 105 enhances the structural strength of the gantry frame 104.

[0039] Furthermore, the telescopic beam assembly 9 includes a first outer sleeve 901 and a second outer sleeve 904, respectively fixedly connected to the two sets of clamping plates 2. The first outer sleeve 901 and the second outer sleeve 904 are connected by a telescopic inner sleeve 902. Locking pin holes 903 are machined at the connection points of the first outer sleeve 901, the second outer sleeve 904, and the telescopic inner sleeve 902, and the locking pin holes 903 are connected by locking pins. The telescopic beam assembly 9 allows adjustment of the distance between the first frame structure 1 and the second frame structure 4, thereby accommodating the clamping of wings of different lengths. Because wings may have different models and lengths, length adjustment is necessary to accommodate the repair of different wing models. Specifically, the length of the telescopic inner sleeve 902 inside the first outer sleeve 901 and the second outer sleeve 904 is adjusted to change the length of the entire telescopic beam assembly 9, thus achieving the purpose of adjusting the distance between the first frame structure 1 and the second frame structure 4.

[0040] Furthermore, the rotating mechanism 5 includes a bearing seat 505 fixed to the top of the gantry frame 104. A tilting shaft 503 is rotatably mounted inside the bearing seat 505. A turntable 502 is fixed to the outer end of the tilting shaft 503. A handwheel 501 is fixed to the periphery of the turntable 502. The inner end of the tilting shaft 503 is fixed to the tilting frame 6 via a locking plate 504. A locking gear ring 7 is fixed to the turntable 502. The rotating mechanism 5 described above can be used to subsequently rotate the tilting frame 6, providing the power for tilting. When it is necessary to tilt the tilting frame 6, the handwheel 501 is rotated, driving the turntable 502, which in turn drives the tilting shaft 503, which in turn drives the tilting frame 6 to rotate.

[0041] Furthermore, the flipping frame 6 includes a rectangular frame 601 fixedly connected to the end of the flipping shaft 503. A support frame 602 is fixed to the outer wall of the rectangular frame 601, and a positioning plate 604 is provided on the support frame 602. A fixing pin 603 is provided on the positioning plate 604. The flipping frame 6 described above can be used to reliably clamp and fix the wing. In the specific fixing process, the wing is supported on the support frame 602 and then locked by the fixing pin 603.

[0042] Furthermore, the foot pedal locking mechanism 3 includes a slide box 303 fixed to the gantry frame 104. A slide rod 302 is slidably mounted inside the slide box 303. A foot pedal 301 is fixed to the bottom end of the slide rod 302, and a pin 304 is hinged to the top end of the slide rod 302. The pin 304 is slidably mounted inside the box body 305. A tensioning spring 307 is installed on the pin 304 and inside the box body 305. A positioning tooth 306 is provided at the top end of the pin 304, and the positioning tooth 306 engages with the locking tooth ring 7. This foot pedal locking mechanism 3 facilitates fixing the angle of the entire flipping frame 6 after the flipping angle adjustment is completed. In the specific operation process, when it is necessary to rotate the tilting frame 6, firstly, by stepping on the foot pedal 301, the foot pedal 301 drives the slide rod 302, the slide rod 302 drives the pin rod 304, and the pin rod 304 drives the top spring 307 to compress, thereby causing the positioning tooth 306 to disengage from the locking tooth ring 7, and thus releasing the lock of the tilting frame 6.

[0043] Furthermore, a dial 10 is mounted on the locking gear 7, which cooperates with the pointer 8. The dial 10 facilitates cooperation with the pointer 8, enabling rapid reading of the rotation angle and ensuring the accuracy of the flip angle control.

[0044] The working process and principle of this utility model:

[0045] With the above-mentioned auxiliary flipping fixture, in the specific use process, when it is necessary to repair and clamp the aircraft wing, firstly, according to the length of the corresponding model of the wing, adjust the telescopic beam assembly 9, and adjust the length of the telescopic inner tube 902 inside the first outer tube 901 and the second outer tube 904 to realize the length of the entire telescopic beam assembly 9, thereby adjusting the distance between the first frame structure 1 and the second frame structure 4.

[0046] Then, the wing is supported on the support frame 602 and locked by the fixing pin 603 to achieve reliable fixation of the wing; then, according to the required angle, the handwheel 501 is turned, the handwheel 501 drives the turntable 502, the turntable 502 drives the tilting shaft 503, the tilting shaft 503 drives the tilting frame 6 to rotate, and then the tilting frame 6 drives the wing to rotate at the corresponding angle in sync;

[0047] Finally, after the angle adjustment is completed, the foot-operated locking mechanism 3 and the locking gear ring 7 are used to lock the position and perform the corresponding maintenance work on the wing.
