Description

technical field [0001] The invention relates to the field of large aircraft component assembly, and in particular, the invention relates to a method for transferring the supporting position of the large aircraft component. Background technique [0002] In the aircraft assembly and docking process, in order to ensure the assembly accuracy, it is necessary to realize the uniform support coordinates of the large parts of the aircraft at different positions. However, the structure of the locator at different stations can be different, for example, the manual locator is used in the partial assembly stage, while the numerical control locator is used in the final assembly stage. The numerical control positioner can realize the advantages of real-time position feedback, accuracy guarantee of grating ruler and self-adaptive positioning. However, the traditional hand-operated locator is movable, which has no accurate position and cannot realize synchronous movement between each hand-...

AI Technical Summary

Problems solved by technology

However, the traditional hand-operated locators are movable, which do not have accurate positions and cannot achieve synchronous movement between each hand-operated locator, which will cause internal stress in aircraft components.

Therefore, it is difficult to achieve real-time and accurate data transmission during the process from using the manual locator station to using the numerical control locator station
