Positioning device for the fabrication of compressor impellers

Abstract

Disclosed is a multi-axis workpiece manipulator or positioning device () having movement along two rectilinear axes (Land L), two pivotable or tilt axes (Tand T) and two rotational axes (Rand R). The positioning device () includes a support base (), a first member () attached to the support base () extending axially therefrom and a carriage () adjustably connected to the first member (). The support base () is movable in a longitudinal path along a first rectilinear axis (L) and the carriage is movable along the first member () in a vertical path along a second rectilinear axis (L). A second member () is pivotably and rotatably attached to the carriage () and extends axially away from the carriage (). The second member () can pivotably move along a first tilt axis (T) with respect to the carriage () and can rotate in a circular path along a first rotational axis (R). A third member () is pivotably and rotatably attached to an end of the second member (), wherein the third member () can pivotably move along a second tilt axis (T) with respect to the second member () and can rotate in a circular path along a second rotational axis (R). A drive mechanism (D) operates the positioning device () for selectively positioning a workpiece (W) to be processed. This device () is particularly useful in fabricating compressor impellers.
