Assembly fixture for a stator vane assembly
A fixture for assembling a stator vane assembly for a gas turbine engine includes, an outer locating ring including a plurality of outer locating pins defining a position for each of a plurality of vanes relative to an outer fairing. An inner locating ring includes a plurality of inner locating rings defining a position of each of the plurality of vanes relative to an inner fairing. A clamp section includes a clamp portion and a clamp pin defining an angular orientation of each of the plurality of vanes relative to each of the inner and outer fairings. An inner locating section supports a plurality of radial locating pins defining a radial position of each of the plurality of vanes relative to the inner and outer fairings.
1. A fixture for assembling a stator vane assembly for a gas turbine engine comprising:
an outer locating ring including a plurality of outer locating pins defining a position for each of a plurality of vanes within a corresponding plurality of outer fairing openings of an outer fairing;
an inner locating ring including a plurality of inner locating pins defining a position of each of the plurality of vanes within a corresponding plurality of inner fairing openings of an inner fairing;
a clamp section including a clamp portion and a clamp pin defining an angular orientation of each of the plurality of vanes relative to each the inner fairing openings and the outer fairing openings, wherein the clamp section holds each of the plurality of vanes such that no part of the plurality of vanes are in direct engagement with the inner fairing and the outer fairing; and
an inner locating section supporting a plurality of radial locating pins defining a radial position of each of the plurality of vanes relative to the inner and outer fairings.
2. The fixture as recited in claim 1 , wherein the fixture defines a first plane with at least three (3) contact points, a second plane with at least two (2) contact points and a third plane with at least one (1) contact point.
3. The fixture as recited in claim 2 , wherein the plurality of outer locating pins on the outer locating ring of the fixture, the plurality of inner locating pins on the inner locating ring and the clamp pin define the first plane.
4. The fixture as recited in claim 3 , wherein the clamp portion is supported on the clamp pin and is configured to hold the vane against the clamp pin, at least one of the plurality of inner locating pins and at least one of the outer locating pins.
5. The fixture as recited in claim 4 , including a fastener for applying a desired pressure to a corresponding one of the plurality of vanes for holding the vane within the defined first, second and third planes.
6. The fixture as recited in claim 3 , wherein each of the plurality of outer locating pins extends transversely from an outer locating surface and each of the plurality of inner locating pins extends transversely from an inner locating surface and the second plane is defined by the outer and inner locating surfaces adjacent the corresponding inner and outer locating pins.
7. The fixture as recited in claim 3 , wherein the radial locating pins include a locating surface transverse to the first plane.
8. The fixture as recited in claim 1 , wherein the clamp section is configured to hold the plurality of vanes during application of a curable material within a space between each of the plurality of vanes and a corresponding inner fairing opening and outer fairing opening.
