Firstly, the composition and work flow of the system are introduced. Based on component measurement feature point data of position and orientation (P&O) from the digital measuring system, relative P&O of the component is calculated by integrated control platform. The parallel P&O adjustment platform is driven to move by control system and the assembly force of components is monitored, to achieve component P&O adjusting and aligning. Secondly, the applications of digital measurement system, P&O adjustment and as-sembly force measurement based on parallel P&O 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 require-ments of flexible aligning between large size components are satisfied, the assembly consistency is improved, and the prod-uct and operator safety is guaranteed.
