Docking measurement pose-adjusting method based on indoor GPS (iGPS)

Abstract

The invention provides a method for docking an object to be measured. The method comprises the steps that i, distribution of measurement points on the object to be measured is determined, and a measuring coordinate system related to a measuring spot is constructed based on the actual measurement positional values and the theoretical positional values of the measurement points; ii, the transformational relation between the measuring coordinate system and the design coordinate system of the object to be measured is constructed; iii, the position information of a pose measuring point and the position information of a drive measurement point are acquired, and the target coordinates to which an actuator corresponding to the drive measurement point is to move is determined based on the transformational relation; and iv, the actuator is driven based on the target coordinates. According to the method, measurement data and the theoretical data of a design model are comprehensively processed, and the digitization, flexibility and automation level of plane docking is improved. According to the technical scheme, the automation level of plane docking can be improved.

Description

technical field [0001] The invention belongs to the field of aircraft assembly, and in particular relates to an iGPS-based large-scale aircraft docking measurement attitude adjustment method. Background technique [0002] In the aircraft manufacturing process, the docking of most parts of the aircraft is one of the most important links. The quality of docking determines the final product performance of the aircraft, and the degree of automation of docking directly affects the efficiency of assembly and the manufacturing cycle. The real-time accurate measurement and control of most parts of the pose is the basis for automatic docking of aircraft. [0003] At present, when carrying out aircraft assembly, especially when connecting large sections such as wing and fuselage, and fuselage and fuselage, the method of fixing tooling frames and manual assembly is still mainly used. In the process of section docking, although the use of digital measurement equipment such as laser tr...

AI Technical Summary

Problems solved by technology

Due to the absence of an integrated automated docking system, aviation companies have not yet realized a complete automated docking and positioning process from component position information collection to pose calculation to driving the driver to complete aircraft component attitude adjustment. The current docking positioning method often requires multiple It takes several adjustments to achieve the accuracy required for docking, and the docking efficiency is very low

[0006] (2) The processing and integration of measurement data is difficult

[0007] At present, laser trackers, collimators and other measurement equipment are mostly used in isolation in assembly measurement, such as positioning, alignment, position tracking, etc., and their measurement data only serve as a reference, and cannot quickly guide and drive the docking process. The adjustment process basically still needs to be completed manually, which greatly affects the assembly efficiency

The measurement data of these digital measurement equipment is only valid for a single process, and cannot be integrated with the data management system and assembly drive equipment, resulting in a waste of resources
