Description

This paper deals with a simple design method for optimizing the support compliance for square parts insertion. A theoretical analysis of the quasi-static inserting process during chamfer crossing is presented under the assumption that no tilting error occurs. The validity of the analysis is examined experimentally. Moreover, the effects of the lateral-to-torsional compliance ratio on the maximum insertion force are revealed by the numerical simulation of the inserting process. Consequently, it is found that an optimum compliance ratio exists where the maximum insertion force is minimized, and that considering the increase rate of the insertion force under each contact condition, a simple method is obtained for determining the desirable compliance ratio for lowering the maximum insertion force. These results are applicable to the optimum design of compliant supports used in automatic square parts assembly.
