| Abstract: | To improve the machining ability of planers, the paper proposes a new type planer, which adopts a parallel mechanism with consideration of the characteristics of parallel kinematics. Some necessary analysis is provided. To get the stiffness model of the parallel type planer, the machine structure is decomposed into several subsystems according to their structures, and then the stiffness of each subsystem is obtained respectively. Finally using the principle of deformation linear superposition, the mechanism stiffness is analyzed. Moreover, the stiffness of machine framework and plane constraint mechanism is also analyzed by FEA method. And the stiffness characteristics is further investigated in simulations and experiments. |
