Description
Technical field
The utility model relates to aircraft engine design fields, and in particular to a kind of stator blade angular adjustment knot
Structure.
Background technique
Inlet casing drives linkage annulus to shake the rotation that arm realizes adjustable vane, the numerical value of rotational angle by pressurized strut
Size is obtained by angle measurement unit, measures rotational angle complex steps by angle measurement unit, and due to sky
Between limitation be easy to cause measurement error.
Summary of the invention
The purpose of the utility model is to provide a kind of stator blade angle adjustment mechanisms, to solve above-mentioned at least one technology
Problem.
The technical solution of the utility model is:
A kind of stator blade angle adjustment mechanism, comprising:
Dial can rotate coaxially, and scale to be integrally formed component with the rocker arm of stator blade with stator blade
The first groove for identifying rotational angle is arranged in disk；
Indicator board is fixed on casing, is provided with close to the side of the dial and is mutually fitted with the first groove of dial
The second groove matched.
Optionally, indicator board is set as vernier scale, and the dial is set as main scale.
Optionally, the first mounting hole is provided on indicator board, casing installation is provided with the second mounting hole on side, and indicator board is logical
First mounting hole, the second mounting hole and bolt is crossed to be fixed on casing installation side.
Optionally, indicator board is set as arc compatible with dial edge close to dial on one side, has scale
A face dial be in same plane.
The utility model has the beneficial effects that
The rocker arm of the stator blade angle adjustment mechanism of the utility model, dial and stator blade is integrally formed component,
It is set as main scale, indicator board is fixed on casing, is set as vernier scale, can directly acquire stator blade by dial
Rotational angle, and data are accurate.
Detailed description of the invention
Fig. 1 is the overall schematic of the utility model stator blade angle adjustment mechanism；
Fig. 2 is the cross-sectional view of the utility model stator blade angle adjustment mechanism；
Fig. 3 is the indicator board scheme of installation of the utility model stator blade angle adjustment mechanism；
Fig. 4 is the A of Fig. 3 to enlarged diagram.
Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.
As shown in Figures 1 to 4, a kind of stator blade angle adjustment mechanism provided by the utility model is started for adjusting
The angle of machine stator blade, the stator blade angle adjustment mechanism include: dial 21 and indicator board 1.
Dial 21 is to be integrally formed component with the rocker arm of stator blade, can be rotated coaxially with the stator blade, and
And the first groove for identifying rotational angle is arranged in the dial 21.By the rocker design of dial and stator blade at one
Body formed component can directly acquire the rotational angle of stator blade by dial, and data are more accurate.
The first mounting hole 11 is provided on indicator board 1, the casing installation is provided with the second mounting hole 12 on side, passes through spiral shell
First mounting hole 11 is fixed on second mounting hole 12 by bolt 3, the indicator board 1 close to the dial 21 one
Side is provided with second groove compatible with the first groove of the dial 21, and the indicator board 1 is close to the dial 21
Be set as arc compatible with 21 edge of dial on one side, be in same with graduated one side and the dial 21
One plane.
By bolted connection rather than welding manner, be because welding manner is not easy to control, weld is easy germinating
Crackle；And mounting hole is arranged to strip hole, can left and right adjusting position, facilitate adjust dial 21 " 0 " graduation mark and refer to
Show " 0 " the graduation mark alignment of plate 1.
Further, in order to reinforce stator blade rotational angle measurement accuracy, set indicator board 1 and dial 21 to
The calibration mode of vernier caliper, the indicator board 1 are set as vernier scale, and the dial 21 is set as main scale, the two composition trip
Mark the rotational angle of the structure measurement stator blade of bevel protractor.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, the change that can be readily occurred in
Change or replace, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with described
Subject to scope of protection of the claims.
