[0024] A moving plate 7 is fixedly installed on the front of the slider 8, a telescopic rod 17 is fixedly installed on the inner side of the moving plate 7, a clamping block 10 is fixedly installed on the inner side of the telescopic rod 17, and a spring 18 is fixedly installed between the clamping block 10 and the telescopic rod 17;

[0025] A pull rod 11 is movably installed inside the clamping block 10 , an extrusion plate 25 is fixedly installed at one end of the pull rod 11 , and a spring 24 is fixedly installed between the top of the extrusion plate 25 and the top inside the clamping block 10 .

[0026] Before the staff connects the wing to the fuselage through the wing joint, it is necessary to fix it. First, hold the pull rod 11, and pull the extrusion plate 25 on the clamping block 10 through the pull rod 11, and squeeze the spring 24 through the extrusion plate 25. Now put the wing into the clamping block 10, and then hold the rocker 4 by hand. The rotation of the manual rocker 4 drives the two-way screw 3 to rotate inside the vertical plate 2 and the slider 8, and then the two sliders 8 rotate inside the slide groove 9, and then the slider 8 drives the moving plate 7 to move toward the outer surface of the wing, and then the moving plate 7 squeezes the telescopic rod 17, the telescopic rod 17 squeezes the clamping block 10, and then the clamping block 10 and the spring 18 are squeezed through the wing. At this time, the two clamping blocks 10 are squeezed and clamped to complete the fixation of the wing.

[0027] Before docking the fuselage through the wing joint, it is necessary to fix the wing, put the wing into the clamping block 10, and then hold the rocker 4 by hand. The rotation of the manual rocker 4 drives the bidirectional screw 3 to rotate inside the vertical plate 2 and the slider 8, and then the two sliders 8 rotate inside the slide groove 9, and the slider 8 drives the moving plate 7 to move toward the outer surface of the wing, and the moving plate 7 squeezes the telescopic rod 17, and the telescopic rod 17 squeezes the clamping block 10, and the two clamping blocks 10 squeeze and clamp. Compared with the traditional positioning tooling, this tooling is convenient for fixing the left and right sides of the wing through the clamping block 10, telescopic rod 17 and spring 1 18, and fixing the upper and lower sides of the wing through spring 2 24, extrusion plate 25 and pull rod 11, which is convenient for fixing the wing, can ensure that the wing joint is accurately fixed in the predetermined position, achieve a perfect match with the main structure of the aircraft, and ensure the stability and safety of the flight. At the same time, this design simplifies the assembly and disassembly process, improves the efficiency of manufacturing and maintenance, and reduces the labor intensity of workers. More importantly, clamping and fixing reduces the risk of operating errors and wing damage, ensures the quality and performance of the wing, and thus reduces the manufacturing cost and maintenance cost.

[0028] Among them, a hydraulic cylinder 5 is fixedly installed at the bottom of the fixed plate 1, a rotating shaft 19 is fixedly installed at the bottom of the hydraulic cylinder 5, and the slide groove 9 is movably installed inside the supporting plate 12, a tooth 23 is fixedly installed on the outer surface of the rotating shaft 19, a motor 21 is fixedly installed at the bottom of the supporting plate 12, a gear 20 is fixedly installed at the output end of the motor 21, and the gear 20 is meshed with the tooth 23.

[0029] When there is a slight difference in the docking angle between the wing and the fuselage, the staff needs to make left and right adjustments. The motor 21 is turned on, and the gear 20 is driven to rotate by the output end of the motor 21. The gear 20 is engaged with the gear 23, and the gear 20 drives the gear 23 to rotate. The rotation of the gear 23 drives the rotating shaft 19 to rotate inside the support plate 12, and the rotation of the rotating shaft 19 drives the hydraulic cylinder 5 to rotate. The rotation of the hydraulic cylinder 5 drives the fixed plate 1 to rotate, and the wing is adjusted left and right by the rotation of the fixed plate 1, thereby completing the left and right adjustment of the wing.

[0030] When there is a slight difference in the docking angle between the wing and the fuselage, it is necessary to adjust the left and right. The motor 21 is turned on, and the gear 20 is driven to rotate by the output end of the motor 21. The gear 20 is meshed with the gear 23, and the gear 23 is driven to rotate by the gear 20. The rotation of the gear 23 drives the rotating shaft 19 to rotate inside the support plate 12, and the rotation of the rotating shaft 19 drives the hydraulic cylinder 5 to rotate. The rotation of the hydraulic cylinder 5 drives the fixed plate 1 to rotate, and the rotation of the fixed plate 1 drives the wing to be adjusted left and right. Compared with the traditional tooling, the tooling is convenient for driving the wing to be adjusted left and right through the cooperation between the rotating shaft 19 and the gear 20, ensuring the precise docking of the wing joint, thereby improving the assembly accuracy, reducing the assembly problems caused by angle deviation, and ensuring flight safety. In addition, the adjustment function simplifies the assembly process, reduces repetitive work, and improves work efficiency. Compared with manual adjustment, the tooling adjustment is simpler and more intuitive, reduces the difficulty of operation, and reduces errors and damage. This function enhances the versatility of the tooling, making it suitable for a variety of aircraft models, and reducing manufacturing costs and maintenance costs.

[0031] A fixing groove 16 is formed inside the support plate 12 , and a tool box 15 is movably installed inside the fixing groove 16 .

[0032] By holding the tool box 15, the tool box 15 is slowly placed into the fixing groove 16, and the tool box 15 is fixed by the fixing groove 16. By adding the tool box 15, workers can easily take out the required tools, avoiding the tedious process of searching for tools at the assembly site, thereby improving work efficiency. At the same time, the orderly storage of tools also reduces the risk of tool loss or damage due to confusion.

[0033] A support column 13 is fixedly mounted on the bottom of the support plate 12 , and a universal wheel 14 is movably hinged on the bottom of the support column 13 .

[0035] The top of the support plate 12 is fixedly mounted with an armrest 6 , and the inside of the armrest 6 presents a U-shaped feature.

[0036] Since the handrail 6 is in a U-shape at the top of the support plate 12 and the U-shaped handrail 6 fits closely to the hands of the workers, it is convenient to directly push the entire tooling to move, thereby reducing the labor intensity of the workers.

[0037] A motor protection cover 22 is fixedly mounted on the outer surface of the motor 21 , and heat dissipation holes are provided on the outer surface of the motor protection cover 22 .

[0038] By opening heat dissipation holes inside the motor protection cover 22 , it is convenient to dissipate heat inside the motor 21 , reduce the temperature inside the motor 21 , extend the service life of the motor 21 , and improve the use efficiency of the motor 21 .

[0039] Among them, the telescopic rods 17 and the springs 18 are grouped in pairs, and there are two groups between the moving plate 7 and the clamping block 10.

[0040] Since the telescopic rods 17 and the springs 18 are arranged in pairs in a total of two groups between the movable plate 7 and the clamping block 10, the cooperation between the telescopic rods 17 and the springs 18 facilitates the squeezing of the clamping block 10, making the wing positioning of the clamping block 10 more stable, thereby improving the efficiency of the clamping block 10 in positioning the wing.

[0041] The working principle and use process of this utility model:

[0042] Before the staff connects the wing to the fuselage through the wing joint, it is necessary to fix it. First, hold the pull rod 11, and pull the extrusion plate 25 on the clamping block 10 through the pull rod 11, and squeeze the spring 24 through the extrusion plate 25. Now put the wing into the clamping block 10, and then hold the rocker 4 by hand. The rotation of the manual rocker 4 drives the two-way screw 3 to rotate inside the vertical plate 2 and the slider 8, and then the two sliders 8 rotate inside the slide groove 9, and then the slider 8 drives the moving plate 7 to move toward the outer surface of the wing, and then the moving plate 7 squeezes the telescopic rod 17, the telescopic rod 17 squeezes the clamping block 10, and then the clamping block 10 and the spring 18 are squeezed through the wing. At this time, the two clamping blocks 10 are squeezed and clamped to complete the fixation of the wing.

[0043] When there is a slight difference in the docking angle between the wing and the fuselage, the staff needs to make left and right adjustments. The motor 21 is turned on, and the gear 20 is driven to rotate by the output end of the motor 21. The gear 20 is engaged with the gear 23, and the gear 20 drives the gear 23 to rotate. The rotation of the gear 23 drives the rotating shaft 19 to rotate inside the support plate 12, and the rotation of the rotating shaft 19 drives the hydraulic cylinder 5 to rotate. The rotation of the hydraulic cylinder 5 drives the fixed plate 1 to rotate, and the wing is adjusted left and right by the rotation of the fixed plate 1, thereby completing the left and right adjustment of the wing.
