In the accompanying drawings and the following description, known structures and technologies are not shown to avoid unnecessary ambiguity in the present invention.

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other, and the embodiments can refer to and quote each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] See attached Figure 1-5 A wing transition beam joint installation device comprises a movable chassis 1, a three-coordinate motion unit 2 and a positioning hole-making bracket 3, wherein the movable chassis 1 is supported on the ground, the three-coordinate motion unit 2 is installed on the movable chassis 1, the positioning hole-making bracket 3 is installed on the top of the Z-direction column 17 of the three-coordinate motion unit 2, the movable chassis 1 is provided with a parking stabilizer 5, a universal wheel 6 and a trailer interface 4, after the entire device is towed to the working area by a trailer and firmly supported on the ground, the wing transition beam joint is connected to the positioning hole-making bracket 3, and the positioning hole-making bracket 3 is driven by the three-coordinate motion unit 2 to move in the horizontal plane and the plumb plane respectively along the three directions of X, Y and Z until the wing transition beam joint reaches the theoretical position for connection and installation with the transition beam, and the wing transition beam joint and the transition beam are drilled and connected together by the fixed drilling template 19 and the handheld drill sleeve 18 on the positioning hole-making bracket 3.

[0029] The movable chassis 1 is a box-shaped structure, the top surface is used to install the three-coordinate motion unit 2, universal wheels 6 are installed at the four corners of the bottom surface, and a trailer interface 4 and a parking stabilizer 5 are installed on the side. After the parking stabilizer 5 is extended to the ground, the entire device can be stably supported on the bottom surface.

[0030] The three-coordinate motion unit 2 is composed of an X-axis slide 11, a Y-axis slide 12, a Z-axis column 17, a sleeve base 16, a ball screw 8, an elevator 13, a slide rail 7, a toothed handwheel 9, a locking pin 10, a pointer 14 and a scale 15. The toothed handwheel 9 is connected to the ball screw 8 or the elevator 13. The X-axis slide 11 is installed on the upper surface of the movable chassis 1 through the slide rail 7. After the toothed handwheel 9 is rotated, it moves along the X direction under the drive of the ball screw 8. The Y-axis slide 12 is installed on the upper surface of the X-axis slide 11 through the slide rail 7. After the toothed handwheel 9 is rotated, it moves along the Y direction under the drive of the ball screw 8. The sleeve base 16 and the elevator 1 3 is installed on the upper surface of the Y-axis slide 12, the Z-axis column 17 passes through the sleeve base 16 and is connected to the elevator 13. After the toothed handwheel 9 is rotated, it moves along the Z-axis column 17 in the sleeve base 16 under the drive of the elevator 13. A pointer 14 is installed on the Z-axis column 17, and a scale 15 is installed on the sleeve base 16 to indicate the lifting distance of the Z-axis column 17. The toothed handwheels 9 in the X, Y and Z directions are all equipped with locking pins 10. When the head of the locking pin 10 is pushed into the tooth groove of the toothed handwheel 9, the toothed handwheel 9 stops rotating, which is used to lock the moving positions of the X-axis slide 11, the Y-axis slide 12 and the Z-axis column 17.

[0031] like Figure 5 As shown, it is a schematic diagram of the Z-axis motion mechanism in the three-coordinate motion unit. The lifting and lowering motion of the Z-axis column in the sleeve base is powered by the elevator (finished product) and guided by the sleeve base. The horizontal transmission form of the elevator is a worm gear, and the plumb bob transmission form is a screw nut. The worm is connected to the toothed handwheel, the worm wheel is connected to the screw, and the Z-axis column is connected to the nut. After turning the toothed handwheel, the worm drives the worm wheel to rotate, the worm wheel drives the screw to rotate, and the screw drives the nut to move, ultimately realizing the lifting and lowering motion of the Z-axis column in the sleeve base.

[0032] The positioning hole-making bracket 3 is composed of a crossbeam 20, a fixed drilling template 19, a handheld drill sleeve 18, an intersection locator 21 and a shape locator 22. The crossbeam 20 is the base of the entire positioning hole-making bracket 3. Its lower surface is installed on the top of the Z-direction column 17, and the upper surface is used to install the fixed drilling template 19, the intersection locator 21 and the shape locator 22. The positioning surfaces of the fixed drilling template 19 and the shape locator 22 coincide with the shape surface of the wing transition beam joint. The handheld drill sleeve 18 is used in conjunction with the fixed drilling template 19 to make the connecting hole between the wing transition beam joint and the transition beam. The installation positions of the fixed drilling template, intersection locator and shape locator on the crossbeam in the positioning hole-making bracket are coordinated with the geometric positioning elements on the wing transition beam joint. The intersection locator is a double-ear structure, and the wing transition beam joint has a single-ear structure. When the wing transition beam joint is connected on the positioning hole-making bracket, the bottom falls on the fixed drilling template and fits with the profile of the fixed drilling template, and the side rests on the shape locator and fits with the profile of the shape locator. The single ear is inserted into the notch of the double ear of the intersection locator and fixed with a locating pin. The positioning and connection of the wing transition beam joint on the positioning hole-making bracket are realized through the above-mentioned geometric elements.

[0033] The specific operation process of using the device to install the wing transition beam joint is as follows:

[0034] 1. Fold the parking stabilizer 5 on the movable chassis 1 to separate the parking stabilizer 5 from the ground;

[0035] 2. Connect the device to the trailer through the trailer interface 4 on the side of the movable chassis 1. After being towed by the trailer to the bottom of the aircraft wing, extend the parking stabilizer 5 until it contacts the ground to ensure that the entire device is firmly supported on the ground;

[0036] 3. Turn the toothed hand wheel 9 of the Z-direction column 17 so that the Z-direction column 17 drives the positioning hole-making bracket 3 to the lowest position, and connect the wing transition beam joint to the positioning hole-making bracket 3 through the intersection locator 21, the shape locator 22 and the fixed drilling template 19;

[0037] 4. Turn the toothed handwheel 9 of the X-axis slide 11 and the toothed handwheel 9 of the Y-axis slide 12 respectively to adjust the wing transition beam joint into position in the horizontal plane, and use the locking pin 10 to lock the positions of the X-axis slide 11 and the Y-axis slide 12 respectively;

[0038] 5. Turn the toothed hand wheel 9 of the Z-axis column 17 to gradually bring the wing transition beam joint closer to the transition beam, and at the same time measure the height difference between the wing transition beam joint and its theoretical installation position. By observing the scale 15, accurately raise and lower the Z-axis column 17 until the height difference is eliminated and the wing transition beam joint reaches its theoretical installation position, and then use the locking pin 10 to lock the position of the Z-axis column 17;

[0039] 6. Use the handheld drill sleeve 18 to make the connection hole between the wing transition beam joint and the transition beam and connect the two together;

[0040] 7. Disconnect the connection between the wing transition beam joint and the positioning hole bracket 3, release the locking pin 10 from the Z-direction column 17 and lower the Z-direction column 17, retract the parking stabilizer 5 and remove the device with a trailer.
