ABSTRACT:
Apparatus for simultaneously gauging and aligning movable elements to a preselected standard is particularly applicable to structures such as guide vane assemblies wherein a plurality of vanes or airfoil elements are supported in radially spaced apart relation by suitable flange means, the apparatus including jaws movable by motor means for aligning both the trailing and leading edges of individual vanes, a monitoring means being incorporated within the jaws to sense initial alignment of the vane and signal the motor means through a suitable amplifier in order to realign the individual vane by means of the motor means and movable jaws. For the preferred application of gauging and bending airfoil elements, the apparatus also includes means for indexing each vane of an annular vane assembly in alignment with the jaw structure as well as additional control elements for facilitating the rapid and accurate gauging and alignment of the vane assembly.
