Description
Technical field
The present invention relates to aircraft engine parts processing technique fields, particularly, are related to a kind of tetrad guide vane casting
Fixture.Moreover, it relates to a kind of listrium base of the tetrad guide vane including above-mentioned tetrad guide vane casting fixture
Quasi- method for processing surface.
Background technique
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 are rotated by a certain angle by 1# blade and are got.Blade is by supramarginal plate, inframarginal, blade group
At.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, and it is anti-that the diagram face G is known as supramarginal plate
End face, the diagram face H 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 entire listrium flatness is difficult to guarantee, and increases mechanical processing difficulty.
The tetrad guide blade structures are complicated, are in temperature highest, the worst part of environment.Its is complex-shaped, blade profile
Position degree, established angle equidimension precision prescribed are high, and difficulty of processing is big.Wherein key factor is that precision positioning is difficult, i.e. the of blade
One benchmark difficulty of processing is big, since following process face is both needed to using to the first benchmark so that final blade profile position guarantee it is difficult.And
Blade profile position degree, established angle are associated with listrium equidimension, and size is difficult to complete qualification.
Blade blank blade, runner are no surplus hot investment casting part, and wherein machine adds position to be mainly upper and lower listrium, from hair
Base has been more than the precision of blade itself to the transformed error that machine adds, these become restricts new engine guide vane matter at this stage
The key factor of amount and qualification rate.
The positioning fixture of existing tetrad guide vane, completely, clamping platen, which is placed on grinding machine, processes listrium for blade positioning
Plane, due to being point location, and machined surface both ends are hanging, no support force, and the unsupported position of grinding process blade is because of stress
Run-off the straight, the listrium plane deviation theory position after causing processing, so that listrium position and size are difficult to ensure, and due to
It is point location, under the action of grinding force, fixture positions club's damaged blade datum mark, keeps processing result untrue, causes most
Whole leaf position degree and established angle are overproof, and qualification rate is less than 60%.
