Abstract
Design and analysis of multi-spindle transmission device helps to improve design quality and efficiency of aggregated machine tools and other automatic mechanical devices. This paper analyzed principles and structures of two multi-spindle transmission mechanisms adopted extensively in mechanical area. A three-dimensional prototype of the multi-spindle drilling device designed for machining six holes simultaneously was built with Pro/Engineer software. The device adopted multi-spindle reciprocating transmission mechanism. The application of the software involved creating simplified model used for motion analysis, performing kinematic analysis of the mechanism, establishing measures of main parameters and executing optimal design of key parts.
