The difficulty of determining regular inspection cycle of digital assembly tooling， dynamic change of assembly condition， and workers’ misoperation， would lead to the out of tolerance for assembly， and cause the difficulty to guarantee assembly cycle. To improve the ability to perceive and predict the geometric and physical quantities of assembly tooling， and enhance the ability to guarantee assembly quality， the research on assembly tooling working condition perception/monitoring/evaluation and adaptive control technologies of assembly positioning are carried out in this paper. As for regular inspection and targeted maintenance before tooling operations， real time monitoring analysis and stability assessment of tooling operation， coordinated control of force position and multi axis in the process of tooling operation， and reduction on out of assembly tolerance， etc， key research on sensing planning for digital assembly tooling measurement， tooling strain and accuracy prediction， tooling service condition description and stability assessment， and site positioning adaptive control were carried out. Then the key technologies of macro and micro locating job condition assessment on assembly tooling， and multi-effectors’ deviation coordination for the assembly accuracy guarantee is proposed. Finally， the multi-point flexible assembly of aviation weak rigid panel test component is taken as example to present the tooling’s positioning precision guarantee for product assembly， the tooling’s adaptive adjustment based on the practical working condition， and the panel’s assembly shape， which laid the tooling foundation for the precision and active control in assembly quality.
