Description
Technical field
The present invention relates to aircraft engine parts processing technique field, especially, is related to a kind of tetrad guide vane cast
Fixture.A kind of moreover, it relates to listrium base of the tetrad guide vane including above-mentioned tetrad guide vane cast fixture
Quasi- method for processing surface.
Background technology
The tetrad guide vane (such as Fig. 1) of gas turbine, belong to tetrad structure, blade is space curved surface, have 1#, 2#, 3#,
Tetra- blades of 4#, 2#, 3#, 4# blade rotate by a certain angle by 1# blades and get.Blade is by supramarginal plate, inframarginal, blade group
Into.The inner N-Side surf of supramarginal plate is known as outer flow passage, and the inner N-Side surf of inframarginal is known as inner flow passage, it is illustrated that it is anti-that G faces are known as supramarginal plate
End face, it is illustrated that H faces are known as inframarginal opposite ends face.This tetrad guide blade structures length is big, and selection of reference frame is difficult, listrium datum level
Difficulty of processing is big, and whole listrium flatness is difficult to guarantee, and adds mechanical processing difficulty.
