METAL-CUTTING WORKING CENTER AND SIX-STRUT MECHANISM FOR IT Russian patent published in 2007 - IPC B23Q1/25 B23Q5/34 

FIELD: metal working processes and equipment, NC-machine tools.

SUBSTANCE: working center includes housing, working table, carrying system made in the form of columns mounted in housing and frame mounted on upper ends of columns, mechanism in the form of six struts of controlled length. First ends of said struts are secured to support being in the form of platform carrying spindle and second ends of said struts are secured to carrying system with the aid of cardan joints. In order to provide possibility for working elongated large-size parts, carrying system is in the form of four columns mounted by pairs at lateral sides of table that may move between them along elongated housing. Said mechanism is in the form of six controlled-length struts. Lower ends of said struts are secured to platform carrying spindle and their mean portions are secured to frame by means of cardan joints. Struts are mounted on frame and on platform in points combined by pairs. Pairs of points form on platform mounting zones in the form of small triangles in plan view and on frame mounting zone in the form of large triangle in plan view.
