Description
Technical field
The utility model relates to compressor blade assembling structure technical fields, more particularly, to a kind of determining for compressor blade
Bit architecture.
Background technique
Conventional compressor blade finished product blade is relatively thin, only blade root, no integral shroud.The common detection of this blade forging and machine add
Work positioning method is: increasing hard origin reference location boss in blade, blade, (or the blade root of blade itself is flat by limitation boss
Face), it is mobile to limit blade, and then achieve the purpose that detect forging and process.
Also, compressor blade is mounted in the race of impeller by its blade root, since the blade root of blade is fir tree shape, dovetail
The blade roots such as type, impeller race are one and are adapted axial pass trough therewith, to guarantee that vaned axial position is consistent on impeller,
And prevent blade from sliding from race, generally use locking key or screw locking.Currently, in the world existing large-scale compressorshaft to
Installation blade positioning method is usually to open locating slot or location hole in wheel rim and blade root platform position, is realized by locking key or screw
The axially position of compressor blade.For this positioning method, locating slot, screw hole may weaken the strong of wheel rim and blade root platform
Degree, influences rotor security.
Instantly, for domestic blade forging horizontally relative to having a certain gap in the world, compressor blade forging is same,
And it is higher to the forging level requirement of forging by the hard origin reference location mode that blade boss positions, need forging consistency of thickness
Very good with profile tolerance, in the case where current forging is horizontal, to reach such forging state cost also be will increase.
Utility model content
To solve the above-mentioned problems, the utility model proposes the utility model to provide a kind of positioning of compressor blade
Structure comprising blade body, the blade root of blade body is in the race of impeller.
The location structure of the compressor blade further includes locking key, is realized axially between blade body and impeller by locking key
Positioning and locking.
The position Ye Ding of the blade body is provided with leaf top technique lug, and the leaf top technique lug offers at least one
A location hole A.
The locking key has leading edge and trailing edge made of a pair of of bending, which is crossed on wheel rim, into
Gas side and trailing edge cooperate with the air inlet side of impeller and outlet side respectively, are stuck in locking key on wheel rim；The locking key
Middle part offers location hole B, and the boss being adapted to location hole B, the height of boss are provided on the blade root bottom surface of blade body
Equal to or slightly less than the thickness of locking key；The locking key only bends a line before assembly, bends another a line again after being packed into race.
Further, a location hole A is offered on the lateral surface of the leaf top technique lug, location hole A is set to
At the center of leaf top technique lug lateral surface.
Further, the locking key is saddle type locking key.
Further, the location hole B in the locking key is square hole, is adapted therewith, convex on blade body blade root bottom surface
Platform is a cube platform.
Further, the location hole B in the locking key is circular hole, is adapted therewith, convex on blade body blade root bottom surface
Platform is cylinder table.
Compared with prior art, the utility model has the beneficial effects that: increasing work using the lateral surface on blade and blade top
Skill lug, and the mode of brill location hole is positioned on technique lug, is splined without on blade root, impeller, is not influenced leaf
The intensity of root platform, impeller, structure is simple, easy to process, easy to assembly；And it is relatively low to the forging level requirement of blade,
Reduce the processing cost of compressor blade.

Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention
Specific embodiment of the present utility model, but the protection scope of the utility model be not limited to it is as described below.
As shown in Fig. 1 ~ Fig. 3, the utility model provides a kind of location structure of compressor blade comprising blade body
1, the blade root of blade body 1 is in the race of impeller 3.
The location structure of the compressor blade further includes locking key 2, is realized between blade body 1 and impeller 3 by locking key 2
Axially position locking.The locking key 2 is saddle type locking key.
The position Ye Ding of the blade body 1 is provided with leaf top technique lug 4, the leaf top technique lug 4 offer to
A few location hole A41.
The locking key 2 has leading edge 22 and trailing edge 23 made of a pair of of bending, which is crossed on 3 wheel rim of impeller
On, leading edge 22 and trailing edge 23 cooperate with the air inlet side of impeller 3 and outlet side respectively, and locking key 2 is made to be stuck in the wheel of impeller 3
On edge；Location hole B21 is offered in the middle part of the locking key 2, is provided on the blade root bottom surface of blade body 1 suitable with location hole B21
The boss 11 matched, the height of boss 11 are equal to or slightly less than the thickness of locking key 2；The locking key 2 only bends a line before assembly,
Another a line is bent again after being packed into race.It should be noted that in the present embodiment, the side of being location hole B21 in the locking key 2
Hole is adapted therewith, and the boss 11 on 1 blade root bottom surface of blade body is a cube platform.
A location hole A41 is offered on the lateral surface of the leaf top technique lug 4, location hole A41 is set to leaf top
At the center of 4 lateral surface of technique lug.
