MAQUINA-FERRAMENTA DE SEIS EIXOS E METODO PARA SITUAR UM OPERADOR EM RELACAO A UM OBJETO

摘要

A pivotable joint usable, for instance, with a multi-legged machine tool, is disclosed. The basic design of the joint includes a central block to which is connected a first yoke pivotably mounted for motion about one axis. A second yoke is also pivotably mounted to the central block for motion about a second axis. The central block includes an opening extending therethrough between two surfaces, and the cross-sectional area of the opening decreases towards the central region of the block. This type of opening permits the use of an extensible mounting leg having a rod that moves through the opening during pivoting of the joint.
