PARALLEL MECHANISM WITH SIX KINDS OF DEGREE OF FREEDOM FOR PRECISION WORK

摘要

PROBLEM TO BE SOLVED: To provide a parallel mechanism with six kinds degree of freedom for precision work, applicable to a wide range in a precision work field requiring various operations by freely executing translation motion and rotary motion of an upper plate by using a linear driving machine capable of controlling the precise position of an outer link and an inner link.;SOLUTION: This parallel mechanism with 6 kinds degree of freedom for precision work, has an upper plate 10 positioned on the upper part, a lower plate 20 positioned on the lower part, a number of outer links 30 connecting the upper plate 10 to the lower plate 20, an a number of inner links 50 for connecting a multi-axes connection spherical joint 40 connected to the center of the upper plate 10 to the lower plate 20. In this case, the inner links 50 are connected centered on the multi-axes connection spherical joint 40 to form a slant face body structure, and the linear driving machine capable of controlling the fine positions is used for the inner links 50 and the outer links 30.;COPYRIGHT: (C)2001,JPO
