Structural Design and Performance Study of Parallel Metamorphic Mechanism Based on Screw System Theory
A new type of metamorphic kinematic pair is designed according to the traditional kinematic pair, and further a novel parallel metamorphic cutting mechanism is designed. Based on screw system theory the constraints of structure branched chain on the end of the moving platform are analyzed before and after transformation, and then the degrees of freedom of the novel parallel metamorphic cutting mechanism is calculated, and the exact axis that the mechanism rotates across can also be obtained.
