Description
Technical field
It the utility model is related to field of mechanical technique, and in particular to one kind is used to repair compressor rotor blade shop bolt
Frock.
Background technology
Aero-engine compressor rotor has been commonly designed shop bolt, and the lower end of shop bolt is inserted on compressor drum barrel
Positioning closing piece screwed hole in, the upper end of shop bolt is clipped between the dividing plate of two panels blade, to rotor blade carry out circumference side
To positioning.General every grade of compressor rotor is designed with 6 shop bolts, it is assumed that certain compressor has 9 grades of rotors (high per grade blade
Degree, size are all different), then share 54 shop bolts.
In the assembling process of shop bolt and rotor blade, shop bolt generally can all protrude dividing plate, and (root of blade is just
Square position is referred to as dividing plate, and effect is that blade is separated certain space) certain altitude, the part of protrusion can hinder air-flow stream
It is logical, change the original direction of air-flow and speed, form flow perturbation, reduce the performance of compressor, it is also possible to cause shaking for blade
It is dynamic, even result in shop bolt and release and injure blade below with air-flow, cause the accidents such as aero-engine surge, parking.Cause
This, it is necessary to make shop bolt as concordant with the cambered surface of blade dividing plate as possible, influence of the dowel pin to Capability of Compressor is reduced to
It is minimum.
At present, in aero-engine assembling, maintenance field, generally take plane needle file filing shop bolt convex with a hand
Go out the part of blade dividing plate.The moving range of file is in interlobate parallelogram region, because the structure of compressor drum barrel
Determine that operating space is smaller with the height of blade, that is, file that the working space repaiied is relatively narrow and small, blade tip, trailing edge and the leading edge of blade
Sharp, easily file hinders hand.Compressor drum barrel is circle, and the working face of plane needle file is plane, because operating space is limited, file
Small volume, the volume of hand it is larger, hold file file when repairing, file is difficult and the arc surface of compressor drum barrel keeps tangent, not phase
Cutting can cause file to hinder compressor drum barrel and blade dividing plate, in practical operation, can nearly all file hinder compressor drum barrel, blade dividing plate and
Blade, compressor drum barrel, blade dividing plate and blade surface is set to have obvious cut.For example the front end filed tilts, it is fixed that wound will be filed
The drum barrel and blade dividing plate of position pinning anterior locations, if file tilts backwards, will file the drum barrel for hindering dowel pin back location
With blade dividing plate.Some enterprises separation sleeve to blade design, when file is repaiied, with separation sleeve wraps up blade, avoids file from hindering
Blade surface around dowel pin, because being required according to the assembling of aero-engine compressor rotor blade and maintenance technique,
These file wounds do not allow, but such a method is not avoided that file hinders blade dividing plate and compressor drum barrel.In addition, separation sleeve
Material can not remain in compressor drum barrel, on blade surface, in order to avoid the material and blade material, compressor drum barrel of residual
Reaction is learned, material contamination is polluted, influences Capability of Compressor.
Simply say, after having assembled primary rotor blade and shop bolt, blade is loaded onto into separation sleeve, it is assorted using plane
File file repaiies the part of shop bolt bulged blade dividing plate.Because operating space is limited, needle file small volume, file wound often occurs
The production accident of compressor drum barrel and blade dividing plate., also can only a certain degree of reduction pair even if extreme care, slowly operating
The degree of injury of compressor blade, blade dividing plate and drum barrel, relatively low which results in operating efficiency, the repair quality of product needs to be carried
The problems such as height, length delivery cycle of product, production cost increase, and operator is easily tired, and production efficiency declines.
In summary, it is badly in need of that a kind of operating efficiency is high, file repaiies that quality is good, structure is simplified, convenient use and has protective
Can maintenance frock to solve problem present in existing aero-engine compressor blade repair technology.
