Description
Technical field
The invention belongs to aero-engine to manufacture technical field of hot, is related to compressor rotor blade in aero-engine
To non-spraying region position the frock of protection in tenon spraying process.
Background technology
The structure of compressor rotor blade 1 as shown in figure 1, it includes blade 11 and is arranged on the tenon 12 of blade one end,
Blade forms compressor rotor by tenon 12 and the assembling of compressor leaf dish.In order to improve the work of compressor rotor blade effect
Rate, compressor operating power consumption etc. is reduced, industrially frequently with density is small, specific strength is high, high temperature resistant and fine corrosion resistance
Titanium alloy makes compressor rotor blade.However, titanium alloy hardness is low, wears no resistance, particularly with being often in fretting wear shape
The compressor rotor blade tenon of state, rotor fails, even leaf destruction can be caused to fly out when serious.
CuNiIn coatings are a kind of soft solid lubricant film layers of excellent combination property, and hardness is low, resistance to Fretting
Good, corrosion resistance and high temperature resistant (use temperature upper limit is 500 DEG C) performance protrude.Turned using plasma spraying technology in titanium alloy
Blades tenon and spraying CuNiIn coatings on rotor leaf dish contact site, can effectively improve blade fretting wear resistance property,
So as to improve aero-engine operating efficiency and service life.
Before plasma spraying is carried out to compressor rotor blade tenon, masking protection need to be carried out to non-spraying region, and
Pre-processed by carrying out blast (the aluminum oxide grains of sand) to spraying area, make spraying area surface roughening, in order to follow-up
The stickup of CuNiIn coatings.The method of non-spraying region generally use adhesive tape is protected at present, specially by thickness
Non-spraying region is pasted for 0.15mm or so aluminum foil and adhesive tape, then to spraying area blast, then by CuNiIn coating sprayings
To the pretreated spraying area of blast.It is oxidized easily yet with spraying area and the adhesive tape of non-spraying region boundary position
The aluminium grains of sand, which blow, to be melted, and forms irregular dentation, and adhesive tape has certain thickness, and spraying terminates after removing adhesive tape, and these regions can shape
Into sawtooth-shaped steps, these zone-coating adhesions are poor, easy cracking so as to causing, and cause coating obscission occur.
The content of the invention
For effective screening can not be realized to non-spraying region present in blade tenon plasma spraying processing procedure at present
The problem of covering protection, the present invention provides a kind of blade tenon spraying positioning protecting tool set-up, to realize to blade tenon non-spraying area
Effective masking in domain, while realize and spraying area is accurately positioned.
The invention provides a kind of blade tenon to spray positioning protecting tool set-up, and the protecting tool set-up is matching used including two
Protect guard member, the coupling member for being linked together two guard members for embracing tenon assembling in tenon both sides non-spraying area
And support base；The guard member includes two supports and the L-type backplate and aerofoil profile backplate that are installed between two supports, institute
State L-type backplate and be designed with face adapted with tenon end non-spraying Region Matching, the aerofoil profile backplate is designed with and tenon waist
The face adapted of matching, non-masked areas matches corresponding with tenon spraying area between the L-type backplate and aerofoil profile backplate；The branch
Support seat include upper disk, lower disc with upper lower disc is connected and fixed together be no less than the connection pillar of 3, on upper disk point
It is furnished with several installing ports for supplying blade insertion；Two guard members embrace tenon end and waist and lock assembling by coupling member
Together, blade is fixed on upper disk after the installing port insertion of upper disk by fixing component.
Above-mentioned blade tenon, which sprays, positions protecting tool set-up, after matching used two guard members L-type guard board association,
Inboard width is more than tenon end portion width, is highly matched with tenon end non-spraying region height, and top is to match somebody with somebody with tenon end
The face adapted of conjunction, so as to which in later stage spraying process, tenon end non-spraying regions shield is protected.
Above-mentioned blade tenon spraying positions protecting tool set-up, is designed on matching used two guard members L-type backplate
There is opening, the aperture that two open butt joints the are formed projection raised with tenon top, which matches, to be fastened in outside projection.
Above-mentioned blade tenon spraying positioning protecting tool set-up, the non-spraying area of the aerofoil profile backplate curved end and tenon waist
Domain is bonded, aerofoil profile backplate side and the following slopes which match of tenon waist, so as in later stage spraying process, by tenon waist and
Protected with the non-spraying regions shield of lower portion.
Above-mentioned blade tenon spraying positioning protecting tool set-up, the coupling member is by connection cover plate and is fixed on connection cover plate
Four latches to match with the pin-and-hole on support are formed, and two guard members embrace tenon end and waist is assembled in one
Rise, latch hole site on four supports is corresponding with the position of four latches on connection cover plate, by two guard members with
Tenon locking fits together.
Above-mentioned blade tenon spraying positioning protecting tool set-up, the fixing component by around upper disk installing port with coupling
The pin-and-hole that four snibbing positions are corresponding on cover plate is formed, and the latch that length is more than backing thickness is worn from the pin-and-hole on support
Cross in the pin-and-hole on the upper disk of insertion, guard member and blade are installed with support base.
Above-mentioned blade tenon spraying positioning protecting tool set-up, the upper disk for forming the support base is ring disk, and lower disc is
The disk of spoke architecture.The support base lower disc is designed with the mounting hole on drive mechanism output revolving shaft, so that
Support base rotates under the driving of drive mechanism around upper and lower disk axis.
The operation principle of above-mentioned blade tenon spraying positioning protecting tool set-up is：By tenon after two guard member assemblings first
End and waist are embraced and fitted together by coupling member locking, by solid after the installing port insertion of blade disk from support base
Determine component to be fixed on disk；On disk multiple blades to be sprayed can be installed simultaneously on each support base；Support base is driving
Motivation structure rotates under driving around upper and lower disk axis, then to the unshielding area between guard member L-type backplate and aerofoil profile backplate
The blade tenon area to be sprayed of domain exposure carries out blast and spray process；After completing the spraying of blade tenon side, it can adjust
Blade direction of insertion, blast and spray process are carried out to blade tenon other side.
Compared to use adhesive tape to blade tenon non-spraying area protection mode, the invention has the advantages that：
