Abstract:

The automatic assembly of aircraft components is generally realized by parallel drive of multiple 3-axis positioners. However, the reconfiguration efficiency and positioning accuracy of single 3-axis positioner have great influence on the assembly efficiency and accuracy of aircraft components. Based on the analysis of the kinematical reverse solution error caused by the geometric errors from positioner with 3-axis randomly position connected in series, positioner with 3-axis randomly position connected in series is designed, and the error compensation model of the kinematical reverse solution is established. The experiment results show that the actual positioning accuracy of positioner with 3-axis randomly positioned series connection is up to 0.025-0.038 mm, which meets the high precision requirements of the new generation aircraft component assembly.

Key words: randomly positioned series connection, 3-axis positioner, positioning accuracy, modeling, assembly
