[0035] Example 1

[0036] Reference Figure 1-5 The wing attitude adjustment tooling is used in the manufacture and assembly of aircraft. In order to facilitate the assembly of the wing, the wing is adjusted and the stability of the wing is improved during adjustment without affecting the assembly of other accessories on the wing.

[0037] The wing attitude adjustment tooling includes two fixing devices, each fixing device is used to fix a wing, the two fixing devices are symmetrically arranged, and a telescopic rod 7 is provided between the two fixing devices. The distance between the two fixing devices can be adjusted by extending and retracting the telescopic rod 7, thereby cooperating with the positioning assembly of the two wings on the aircraft. In this embodiment, the telescopic rod 7 adopts a plurality of sleeves to make the telescopic rod 7 retractable. The telescopic principle is the existing technology and will not be repeated here. The telescopic rod 7 can be disassembled from the two fixing devices, so that the tooling is connected as one when in use, meets the requirements of anti-displacement and anti-dumping, improves stability during work, and can be divided into two monomers when evacuating the scene, which is convenient for moving to the parking area, thereby improving work flexibility.

[0038] Each fixing device includes a frame and two adjustment mechanisms, and each adjustment mechanism includes a transverse movement component 2 arranged on the frame. The transverse movement component 2 includes a transverse adjustment handwheel 201, a transverse threaded rod 202, a transverse slide rail 203 and a transverse movement plate 204. The transverse threaded rod 202 and the transverse slide rail 203 are both arranged on the frame 1. The transverse adjustment handwheel 201 is fixedly connected to one end of the transverse threaded rod 202, and the transverse movement plate 204 is slidingly connected to the frame 1 through the transverse slide rail 203, and a first threaded sleeve 205 is provided at the bottom of the transverse movement plate 204. The first threaded sleeve 205 is threadedly connected to the transverse threaded rod 202. By rotating the transverse adjustment handwheel 201, the transverse threaded rod 202 can be driven to rotate, and the transverse threaded rod 202 rotates inside the first threaded sleeve 205, so that the first threaded sleeve 205 drives the transverse movement plate 204 to move along the transverse slide rail 203 for transverse adjustment.

[0039] Each adjustment mechanism also includes a longitudinal movement component 3 arranged on the transverse movement plate 204, and the longitudinal movement component 3 includes a longitudinal adjustment handwheel 301, a longitudinal threaded rod 302, a longitudinal slide rail 303 and a longitudinal movement plate 305. The longitudinal threaded rod 302 and the longitudinal slide rail 303 are both arranged on the transverse movement plate 204, and the longitudinal adjustment handwheel 301 is fixedly connected to one end of the longitudinal threaded rod 302, and the longitudinal movement plate 305 is slidingly connected to the transverse movement plate 204 through the longitudinal slide rail 303, and a third threaded sleeve 304 is provided at the bottom of the longitudinal movement plate 305, and the third threaded sleeve 304 is threadedly connected to the longitudinal threaded rod 302. By rotating the longitudinal adjustment handwheel 301, the longitudinal threaded rod 302 can be driven to rotate, and the longitudinal threaded rod 302 rotates inside the third threaded sleeve 304, so that the third threaded sleeve 304 drives the longitudinal movement plate 305 to move along the longitudinal slide rail 303 for longitudinal adjustment.

[0040] The transverse moving assembly 2 and the longitudinal moving assembly 3 are arranged perpendicular to each other, so that the tooling can be adjusted transversely and longitudinally on a horizontal plane.

[0041] Each adjustment mechanism also includes a vertical movement component 4 and a support 5 arranged on the longitudinal movement plate 305. The vertical movement component 4 includes a housing 401, a worm gear 402, a worm 403 and a vertical adjustment hand wheel 404. The housing 401 is arranged on the longitudinal movement plate 305. The worm gear 402 is rotatably connected to the interior of the housing 401. The inner ring of the worm gear 402 is provided with a second threaded sleeve 405. The support 5 passes through the worm gear 402 and is threadedly connected to the second threaded sleeve 405. One end of the worm 403 is horizontally inserted into the housing. The inside of the body 401 is engaged with the worm gear 402, and the other end of the worm 403 is fixedly connected to the vertical adjustment hand wheel 404. A vertical slide groove 501 is provided on the outside of the pillar 5, and a slider 502 is provided on the shell 401. The slider 502 is located inside the vertical slide groove 501. By rotating the vertical adjustment hand wheel 404, the worm 403 can be driven to rotate, thereby driving the worm gear 402 to rotate, and the second threaded sleeve 405 on the inner ring of the worm gear 402 rotates, thereby driving the pillar 5 to move vertically along the vertical slide groove.

[0042] Each fixing device also includes a bracket 6, and the upper ends of the two pillars 5 are provided with a fixing rod 8, the upper ends of the fixing rod 8 are spherical, and movable seats 9 are provided on both sides of the bottom of the bracket 6. The bottom of the movable seat 9 is provided with a spherical groove, and the spherical upper end of each fixing rod 8 is located inside a spherical groove, so that the bracket 6 is set at the top of the pillar 5 of the two adjustment mechanisms. Two adjustment mechanisms are set on each frame 1, so that the height of the front and rear ends of the bracket 6 can be adjusted respectively to adjust the angle of the wing on the bracket 6, further improving the flexibility of positioning and docking of the wing and the fuselage, and facilitating the aircraft to move freely. The wing is precisely docked with the fuselage. When one of the pillars 5 is adjusted individually by the vertical adjustment hand wheel 404, the spherical upper end of the fixing rod 8 can move inside the spherical groove, thereby facilitating the rotation between the bracket 6 and the pillar 5. Moreover, since there is a certain assembly gap between the spherical upper end of the fixing rod 8 and the spherical groove, the heights of the two pillars 5 can be fine-tuned within a certain range, so that the tooling can adapt to uneven ground and ensure that the fuselage posture on the bracket 6 is level. In addition, a bubble-type level is installed on the bracket 6 to facilitate visual observation of whether the tooling is level.

[0043] In this embodiment, the wing attitude adjustment tooling also includes two fixing straps 601, and a hook is provided on the bracket 6. Each fixing strap 601 is fixed to a bracket 6 through the hook. The wing can be fixed to the bracket 6 through the fixing strap 601, thereby further improving the assembly stability of the tooling to the wing, and a pad is provided on the top of the bracket 6, and the top of the pad is arc-shaped to fit the lower surface of the wing. The pad is made of high-strength, corrosion-resistant, and high-temperature resistant nylon pad or other non-wood-like lightweight materials, and the contact part with the lower surface of the wing is made of soft material to protect the lower surface of the wing.

[0044] Universal wheels 101 are provided at the bottom of the frame 1 to facilitate the movement of the tooling.

[0045] Example 2

[0046] The wing attitude adjustment tooling, in order to increase the stability of the tooling when supporting and fixing the wing, a fixing plate is provided at the bottom of the frame 1, a threaded hole is opened on the fixing plate, a fixed threaded rod is provided inside the threaded hole, and a fixed seat is provided at the lower end of the fixed threaded rod. By rotating the fixed threaded rod, the fixed seat can be lowered to contact the ground, so that the tooling is fixed by the fixing seat, thereby improving the stability of the tooling.

[0047] The working principle of the wing attitude adjustment tool is as follows: when in use, the two fixing devices are pushed to the designated area via the universal wheels 101, and then the frames 1 of the two fixing devices are connected via the telescopic rod 7 to form a whole, which can effectively prevent the tool from tipping over. The telescopic rod 7 can be extended and retracted to adjust the distance between the two frames 1, thereby coordinating the positioning and assembly of the two wings on the aircraft;

[0048] The wing is hoisted onto the bracket 6 using a hoisting device, with the lower surface of the wing in contact with the upper surface of the bracket 6. The wing is then secured to the bracket 6 by tightening the fixing strap 601 around the front and back of the wing. The ends of the fixing strap 601 are fixed to the bracket 6, thereby securing the wing to the tooling.

[0049] When lateral adjustment is required, the lateral threaded rod 202 is driven to rotate by rotating the lateral adjustment hand wheel 201. The lateral threaded rod 202 rotates inside the first threaded sleeve 205, so that the first threaded sleeve 205 drives the lateral movable plate 204 to move along the lateral slide rail 203 for lateral adjustment.

[0050] When longitudinal adjustment is required, the longitudinal adjustment hand wheel 301 is rotated to drive the longitudinal threaded rod 302 to rotate, and the longitudinal threaded rod 302 rotates inside the third threaded sleeve 304, so that the third threaded sleeve 304 drives the longitudinal movable plate 305 to move along the longitudinal slide rail 303 to perform longitudinal adjustment;

[0051] When vertical adjustment is required, the vertical adjustment hand wheel 404 is rotated to drive the worm 403 to rotate, thereby driving the worm wheel 402 to rotate, and the second threaded sleeve 405 on the inner ring of the worm wheel 402 to rotate, thereby driving the support 5 to move vertically along the vertical slide 501. By rotating the two vertical adjustment hand wheels 404 at the same time, the two supports 5 can be raised and lowered at the same time, and the entire fuselage can be raised and lowered over a large range.

[0052] When one of the pillars 5 is driven to rise and fall independently, the horizontality of the bracket 6 can be fine-tuned. In the actual assembly process of the various components of the tooling, since there is an assembly gap between the two pillars 5 and the bracket 6, within a certain range allowed by the height difference between the two pillars 5, one pillar 5 can be driven to rise and fall independently to fine-tune the horizontality of the bracket 6, so that the tooling can adapt to uneven ground. It should be noted that during the fine-tuning process of the bracket 6, the height difference between the two pillars 5 must be controlled within 3 cm. At this time, the assembly gap between the pillar 5 and the bracket 6 is sufficient. When the two pillars 5 are of different heights, the bracket 6 does not affect the lifting of the two pillars 5.

[0053] The wing and fuselage can be positioned and docked through horizontal, longitudinal and vertical adjustments, making assembly easier;

[0054] After the assembly is completed, the aircraft is supported by a jack to separate the tool from the fuselage. At this time, the telescopic rod 7 can be disassembled to separate the two frames 1, thereby facilitating the separation and evacuation of the tool.

[0055] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
