Abstract

The invention discloses a mechanism for quickly positioning airplane components. The mechanism is provided with a guiding and positioning mechanism and a limited seat which cooperates with the guiding and positioning mechanism, wherein the guiding and positioning mechanism is provided with a positioning shaft; the positioning shaft is cylindrical; connecting shafts are respectively arranged at two ends, in the positioning shaft, and are connected with holes in the airplane components; an axial limited block is arranged on the positioning shaft, and is arranged in the middle of the positioning shaft in a sleeving manner; the limited seat is provided with a base; an axial positioning groove is formed in the base, and cooperates with the axial limited seat so as to perform axial positioning on the guiding and positioning mechanism. Through the adoption of the mechanism disclosed by the invention, the purposes that the airplane components are quickly positioned and connected when being mounted at different work positions or being remounted are realized; the positioning flexibility of the airplane components and the mounting flexibility of the airplane components are realized; products are adapted to being mounted, dismounted and transferred at different work positions on a production line; the production preparation cycle is shortened; the cost for researching and manufacturing airplanes is reduced.

Description

technical field [0001] The invention belongs to the technical field of aircraft assembly, and in particular relates to a rapid positioning mechanism and positioning method for aircraft components, which are used for rapid positioning and connection of aircraft components. Background technique [0002] The aircraft manufacturing process is complex, from parts to components, components to the entire aircraft process, there are many links, product parts need to be positioned and installed multiple times, especially the repositioning of large parts, its positioning accuracy and efficiency have a greater impact on the aircraft manufacturing cycle Big. Traditional aircraft manufacturing adopts analog coordination, and important positioning references, such as intersection holes, important mating surfaces, and positioning grooves, have disadvantages such as low repeat positioning accuracy and long operating time when the upstream and downstream processes flow, which restricts the a...
