COMPENSATING SYSTEM FOR HEXAPOD

摘要

The invention concerns a hexapod, for example a hexapod used for positioning a tool relative to a part to be machined, comprising two spaced plates mutually connected by six extensible legs and articulated for varying at will the mobile plate (2) relative position with respect to the base plate. The invention is characterised in that it is equipped with means decreasing in compensation the stresses on the hexapod elements. The compensating system is for example an actuating cylinder (S1) maintained by a fixed frame (6), the cylinder rod being fixed at the mobile plate periphery.
