Analysis and Simulation of a Hybrid Mechanism with 2R-3T of Special Machining Platform

Abstract:

This paper designs a platform which is used for material pose alignment of complex curved surface parts laser processing. The parallel platform is based on a hybrid mechanism with five spatial degrees of freedom. The mechanism is built up by three parallel vertical chains {(P-R-C), (C-R-C-R), (P-H)} and two series single opened chains {(P), (P)}. This processing platform is an ideal hybrid platform with 2R-3T, and it has the advantages of both the parallel mechanism and the series mechanism. The DOF (degree of freedom) of the parallel mechanism is calculated and the positions of the moving platform are analyzed. The results of the position-equations are simulated by using ADAMS software. It is shown that the processing platform is able to meet the requirements of any angle positions of various materials processing, and realize material special machining.
