To realize digitization and flexibility during large size

heavy

multi-constrained cabin components aligning

a novel digital flexible aligning system of cabin components is developed. Firstly

the composition and work flow of the system are introduced. Based on component measurement feature point data of position and orientation (PO) from the digital measuring system

relative PO of the component is calculated by integrated control platform. The parallel PO adjustment platform is driven to move by control system and the assembly force of components is monitored

to achieve component PO adjusting and aligning. Secondly

the applications of digital measurement system

PO adjustment and assembly force measurement based on parallel PO adjustment platform and functional design of integrated control platform are given. Finally

the experimental study of components aligning is completed. Experimental results show that the requirements of flexible aligning between large size components are satisfied

the assembly consistency is improved

and the product and operator safety is guaranteed.
