Machine tool equipped with position and posture separation type parallel mechanism

摘要

The present invention relates to a positional, posture separated driving parallel mechanism for a machine tool, comprising: an upper parallel mechanism composed of a base and a platform, three linear actuators, top and bottom, left and right and front and rear linear motion guides; It consists of a lower parallel mechanism consisting of a base, a platform, a central axis assembly, and three linear actuators, and by adjusting the length of the linear actuator of the upper parallel mechanism, it pushes and pulls the platform equipped with the machining tool in an arbitrary space. The parallel mechanism adjusts the lengths of the three linear actuators in the posture of the platform where the workpiece is fixed, in the io, pitch, and roll directions to determine the posture of the workpiece to process the workpiece.
