The purpose of this utility model is achieved through the following technical solutions：
This kind of aero engine turbine blades clean positioning fixture, and the positioning fixture is determined by support component, upper strata liftable
Position adjustment component and lower floor's positioning adjustment component composition, it is characterised in that：
Support component includes a base (1) and the balladeur train (2) being vertically fixed on base (1)；
Upper strata liftable positioning adjustment component includes installing a square frame shape lifting that can be moved up and down along balladeur train (2)
Frame (3), crane (3) fixes its position on balladeur train (2), four of square frame shape crane (3) by bolt (4)
The center of frame is provided with the blade that the clamping screw of ecto-entad precession (5) is inserted into crane (3) frame with fixation
(6) upper position；
Lower floor's positioning adjustment component is included in three faces fixed on base (1) frame, the rectangle of one side opening
Adjustment seat (7), on the frame of adjustment seat (7) opening both sides it is each install one be capable of it is transverse shifting, ecto-entad precession
Lateral clamping screw (8), the transverse shifting of lateral clamping screw (8) is mobile next real along the transverse groove (9) processed on frame
Existing, a bearing (10) is set at adjustment seat (7) aperture position, one ecto-entad precession of installation on bearing (10)
Positive clamping screw (11), adjustment and blade are provided at the top of lateral clamping screw (8) and positive clamping screw (11)
(6) movable block (12) in bottom laminating direction, is provided with for preventing on the binding face of movable block (12) with blade (6) bottom
The film protection pad (13) of impact injury blade, in addition, being also equipped with neonychium on adjustment seat (7) is open relative frame
(13)。
The utility model has the advantages that being one fixed stably by aero engine turbine blades and the unification of double orientation fixture
Fixed overall structure, and blade (6) is realized to position by adjusting clamping screw (5) and movable block (12).This kind of fixture can be with
The positioning cleaning of tenon position turbo blade in irregular shape is realized, and due to the combination using upper and lower double-decker
Adjustment, improves the stability of tenon position turbo blade positioning in irregular shape, has both solved the difficult problem of turbo blade positioning,
Solve the problems, such as to depart from fixture in high-pressure jet water slug lower blade again.
