Online programming technique for flexible assembly of fuselage

In order to meet the deep flexible demands of “one fixture with more models” and “one fixture with more states” for digital assembly of fuselage, enable the “bridge-frame” flexible tooling to have better capacity for independent adaptability, its kinematic model must be set up and its movement controls strategy must be planned properly by online programming technique. For the locating styles of fuselage and the characteristics of flexible tooling, the kinematic model of flexible tooling was set up, then simulation model-based online programming disciplines, the way of building reference points for assembly and the technology of movement controls strategy planning were studied. The way of building a process-driven simulation environment based on structure function was proposed. In order to generate the codes quickly to control motion, the online programming system for flexible assembly of fuselage was developed. With the assembly of rear fuselage, for example, the accuracy, high efficiency and strong independent adaptability of this system were verified.
