GENERAL PURPOSE ORTHOGONAL AXES MANIPULATOR SYSTEM

摘要

A gantry type orthogonal axes manipulator system including a rack and pinion mechanical drive for the X and Y axis assemblies and a ball screw mechanical drive for the Z axis assembly employs closed loop DC servo electrical drives controlled by the conventional numerical control techniques. A rotary index feature permits horizontal rotation of the Y axis assembly, which supports the Z axis assembly, at the end of travel of the X axis assembly to service work zones on either side of the X axis assembly.
