ABSTRACT:
The present invention is a vane adjustment machine for adjusting contoured vanes on a vane ring. The vane adjustment machine has a support structure with a bench top and a free-floating suspension. The bench top supporting a programmable rotary table which is electrically actuated to rotate a removably mounted vane assembly to bring each contoured vane into a position to be dimensionally measured, heated, and bent. The vane adjustment machine has a trace probe mounted adjacent to the rotary table for engaging each contoured vane and measuring its relative position radially and axially. A torch is mounted adjacent the rotary table to heat each contoured vane individually. A non-contact infrared sensor is on the bench top adjacent to the torch for measuring the temperature of a heated contoured vane. A bending head is suspended by the free-floating suspension over the vane ring to individually engage the trailing edge of each individual contoured vane and bend the-trailing edge to adjust the contoured vane. The bending head has a jaw assembly comprising a fixed jaw and a movable jaw. The jaw assembly engages the trailing edge with two feet and a center portion to bend the contoured vane. The jaw assembly has an adjustment for changing the spacing and the angular relationship between the feet to accommodate a variety of different sized contoured vanes. The fixed jaw and the moving jaw may be configured to open or close an exit area defined by the trailing edge of the contoured vane and the inner and outer nozzle rings.
