Problems solved by technology

The traditional leading edge positioning tool has a large size and structure, and resin and spacers are used to adjust the position of the positioning tool. This method takes a long time and depends on the proficiency of the worker's operation. In addition, the resin needs to be broken for each repositioning, which is labor-intensive. , the degree of automation is low, which is not conducive to the digital assembly of aircraft

Embodiment

[0029] see Figure 1 to Figure 5 , The aircraft wing box leading edge process joint positioning tool includes a base unit 9 , a bracket 6 , an adjustment unit 5 and an intersection positioning plate 1 .

[0030] The base unit 9 includes a bottom plate, a horizontal adjustment block and a vertical adjustment block. The horizontal adjustment block and the bottom plate are connected in a horizontal sliding manner through a horizontal guide rail slider mechanism, and a horizontal fine-tuning mechanism is provided between the horizontal adjustment block and the bottom plate, which has an X-direction degree of freedom; The adjustment block and the horizontal adjustment block are slidingly connected in the longitudinal direction through the longitudinal guide rail slider mechanism, and a vertical fine-tuning mechanism is arranged between the vertical adjustment block and the horizontal adjustment block, which has a Y-direction degree of freedom. The top of the bottom plate is provide...

Abstract

The invention discloses a positioning tool of an aircraft wing box leading edge technological connector and belongs to the technical field of aircraft assembly. The positioning tool comprises a base unit, a support connected with the base unit and an intersection point positioning plate connected with the support. An adjusting unit is further arranged between the intersection point positioning plate and the support. The adjusting unit comprises a connecting plate, a first adjusting plate and a second adjusting plate. The connecting plate is connected with the support through a locking bolt, the first adjusting plate is rotatably connected with the connecting plate through a transverse rotary shaft, and the second adjusting plate is rotatably connected with the first adjusting plate through a longitudinal rotary shaft. Tapered bosses are evenly distributed on the second adjusting plate, tapered grooves matched with the tapered bosses are formed in the intersection point positioning plate, and the intersection point positioning plate penetrates through the second adjusting plate through a threaded positioning pin to be connected with the first adjusting plate. The intersection point positioning plate is provided with an interval spacer through the positioning pin. The positioning tool of the aircraft wing box leading edge technological connector is simple in structure and high in automatic degree.

Description

technical field [0001] The invention belongs to the technical field of aircraft assembly, and in particular relates to a positioning tool for a process joint at the leading edge of an aircraft wing box. Background technique [0002] Aircraft assembly technology has gone through the process from manual assembly, semi-mechanical and semi-automatic assembly to fully mechanical and fully automated assembly. Nowadays, aircraft digital assembly occupies the mainstream of aircraft assembly process. The digitalization degree and assembly quality of aircraft wing box assembly are directly related It is related to the quality of the digital assembly of the entire aircraft, among which the hoisting and positioning of the leading edge of the wing box is particularly critical. The traditional leading edge positioning tool has a large size and structure, and resin and spacers are used to adjust the position of the positioning tool. This method takes a long time and depends on the proficie...
