6 6 Degree-of-freedom Parallel Mechanism for Micro-positioning Task

摘要

The present invention is precisely a work that can be utilized, a wide range from the precision work areas that require a variety of operations by performing a translational motion and the rotational motion of the upper plate using a linear actuator capable of precise position control of the external links and internal links freely six degrees of freedom it is an object to provide a parallel mechanism.; The present invention for achieving the object above, the precision work six degrees of freedom in, and the top plate 10 which is located at the upper, and the lower panel (20) positioned at a lower portion, the upper plate 10 and the lower plate in a parallel mechanism (20 ) to include a plurality of outer links 30 and, a multi-screw connection spherical joint 40 and the lower plate 20, a plurality of inner ring 50 to connect the coupling to the center of the top plate 10 for connection. Here, the multi-axis connecting the spherical joints (40) about said plurality of inner ring 50 with an are connected to form a tetrahedral structure, the inner ring 50 and the outer link (30) includes a possible linear fine positioning control the actuator is used.
