It is used to process the large-scale frock for practicing stator blade the invention discloses a kind of more, it includes working base and the supporting mechanism for location and hold-down mechanism that are arranged on working base, supporting mechanism for location includes stationary positioned supporting mechanism and auxiliary location support mechanism, and hold-down mechanism includes blade hold-down mechanism and small end listrium auxiliary hold-down mechanism.The Fast Installation positioning of the large-scale multi-joint stator blade class part of combustion engine can be achieved by the mutual cooperation between each supporting mechanism and hold-down mechanism in the present invention；And the position stability to processing part is improved, effectively avoid part from being weighed wounded, it is ensured that part crudy.
Description
Technical field
The invention belongs to aero-engine manufacturing technology field, is related to large-scale gas turbine stator blade process technology,
The multi-joint stator blade processing tool of the large-scale combustion engine of basic circle curved face processing is realized in particular for six point locations.
Background technology
Gas turbine is the staple product in large-scale combustion engine field, and blade is the heart of gas turbine, therefore blade
Crudy concerns the normal operation and service life of whole gas turbine.It is well known that blade processing is gas turbine manufacture
In one of most difficult process, particularly large-scale this kind of special-shaped part of multi-joint stator blade, because its used material is nickel
Base high temperature meets material PWA 1498, and processing characteristics extreme difference during adding again to reference plane, it is necessary to position；Particularly adopt
With Milling Process, milling active force is big, if positioning is unstable, part roughness and quality after milling it is difficult to ensure that, it is while right
Stage property loss is also larger.
At present, positioning method commonly used in the art includes two kinds：(1) processing first has and parts to be processed reference plane
The low-melting alloy support base of matching, then parts to be processed is placed on low-melting alloy support base and is processed；(2) exist
Some pillars for being matched with parts to be processed reference plane are set on the higher support base of hardness as datum mark, pillar with it is to be processed
Part reference plane contacts for point, so as to realize the positioning processing to parts to be processed.Because large-scale multi-joint stator blade is four
Join blade, a maximum grade blade length has reached 440 × 385 × 115mm, and weight has reached 15Kg, it is difficult to using conventional
Low-melting alloy support base realizes positioning processing；According to second of positioning method, due to blade to be processed weight and size is big, leads to
Six point locations are crossed, position stability in process cannot be ensured, easily loosened, blade is so easily caused and is weighed wounded appearance
Vestige, so as to be difficult to ensure that blade processing quality.
In summary, for the multi-joint stator blade class special-shaped part of large-scale combustion engine, stability can be realized at present by lacking
Positioning, effectively avoid the processing tool that part weighs wounded.
The content of the invention
For in the current large-scale multi-joint stator blade process of combustion engine due to position it is unstable caused by blade processing
The technical problem that quality is difficult to ensure that, the present invention provides a kind of to be used to process the multi-joint guider of large-scale combustion engine with sufficiently rigid
