Description
Technical field
The present invention relates to disc part of aero-engine dovetail groove original position ultrasound detections, especially provide a kind of diskware dovetail groove
Ultrasonic inspection probe in situ.
Background technology
Three-level disk is one of main stress part of engine, it is with I and II disk sub-assembly, preceding axle journal and four~nine grades
Disk sub-assembly is bolted into high-pressure compressor rotor by 60, is rotated as the main member of rotor with being carried out at high speed, disk
Once destroying, consequence is often catastrophic.The breakage of diskware punches engine crankcase, can cut off oil circuit or behaviour
Vertical system, penetrates fuel tank and cockpit, constitutes a serious threat to aircraft and driver, therefore its reliability will directly affect flight
Safety.The diskware dynamic load that rotor blade generates in use can make disk dovetail groove force part generate fatigue crack, because
This has engine overhaul file to add to the requirement of three-level wheel disc dovetail groove location ultrasound detection, since diskware oat tail groove structure is answered
It is miscellaneous, it is not suitble to the ultrasonic probe of detection, can not realizes ultrasound detection.
The content of the invention
It is an object of the invention to according to three-level disk oat tail groove structure feature, design a kind of dedicated probe, realize three-level disk
Dovetail groove in situ detection.
The technical scheme is that：A kind of diskware dovetail groove original position ultrasonic inspection probe, including：Frock 1, probe 2, coupling
Mixture water delivery pipe 3, multiple springs 4, pipe fitting (5)；
The whole cavity 6 for being in cuboid, front and rear perforation being offered among 1 lower part of frock of the frock 1, the frock
1 lower surface for corresponding to cavity 6 includes one section of curved surface 1a, and the 1 lower part both sides of frock form column 1b；The frock 1 is equipped with
Vertical direction through hole and the horizontal direction through hole with the perforation of vertical direction through hole opened up in 1 one side of frock, the probe 2 are inlayed
In the vertical direction through hole of frock 1, the couplant water delivery pipe 3 is arranged in horizontal direction through hole, and the couplant water is defeated
3 end of pipe is sent to be equipped with pipe fitting 5, the upper surface of the couplant water delivery pipe 3 is concordant with the lower surface of the chip 2a of probe 2；
The multiple spring 4 is fixed on column 1b, and its one end protrudes from column 1b inner surfaces can simultaneously stretch in cavity 6.
Preferably, 4 quantity of spring is 6, and points 3 groups symmetrical to be set at equal intervals.
Preferably, 4 quantity of spring is 3, at equal intervals on same column 1b.
Preferably, the frock 1 is plastic body.
The present invention has following beneficial effect：
The present invention can realize that three-level disk dovetail groove detects, simple in structure, easy to operate, cost is relatively low, can in other factory, repair
Reason factory is detected three-level disk dovetail groove, can be avoided with quality at effective monitoring three-level disk dovetail groove because of diskware fatigue crack
The engine accident cost brought, while preciousness can be provided for the in situ detection of the dovetail groove of other model engine diskwares
Experience.

Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, 2, a kind of diskware dovetail groove original position ultrasonic inspection probe, including：Frock 1, probe 2, couplant water
Delivery pipe 3, multiple springs 4, pipe fitting 5；
The whole cavity 6 for being in cuboid, front and rear perforation being offered among 1 lower part of frock of frock 1, frock 1 correspond to cavity 6
Lower surface includes one section of curved surface 1a, and 1 lower part both sides of frock form column 1b；Frock 1 is equipped with vertical direction through hole and in frock 1
The horizontal direction through hole with the perforation of vertical direction through hole that one side opens up, probe 2 are embedded in the vertical direction through hole of frock 1,
Couplant water delivery pipe 3 is fixed in through hole in the horizontal direction, and 3 end of couplant water delivery pipe is equipped with pipe fitting 5, and couplant water is defeated
The upper surface for sending pipe 3 is concordant with the lower surface of the chip 2a of probe 2；Multiple springs 4 are fixed on column 1b, and its one end protrudes from
Column 1b inner surfaces can simultaneously stretch in cavity 6.
Frock 1 of the present invention can be slided on the boss beside dovetail groove, and 6 two heel post 1b of side of cavity can be steadily horizontal
Across on the boss beside dovetail groove；The lower surface that frock 1 corresponds to cavity 6 includes one section of curved surface 1a, beside dovetail groove
The curved surface of boss is consistent；Using water coincidence, water into couplant water delivery pipe 3 and enters 2 lower section of probe by pipe fitting 5,
The acoustic beam that probe 2 is sent is propagated to by couplant water on boss, is penetrated boss and is continued to travel at dovetail groove, if dovetail groove
There is fatigue crack at place, and ultrasonic wave will reflect, and is received along backtracking by probe, display defect ripple at the gate on oscillography screen,
Realize detection.
Frock 1 using cuboid plastics by the design of three-level disk projection shape, can be across on boss and can be along dish axle to shifting
Dynamic, probe 2 is embedded in frock 1, and pipe fitting 5 is connected in frock 1, and upper surface is concordant with the chip 2a lower surfaces of probe 2,
Couplant water can flow to the chip 2a of probe 2 just by couplant water delivery pipe 3 in the following, excluding the air in frock cavity,
2 acoustic beam of probe is made to be traveled to by couplant water on three-level disk boss, spring 4 is connected with frock 1, its effect is frock insertion
Need pressing spring 4 during three-level disk boss, distance becomes larger between two column 1b, and frock 1 is easily put into boss, is put into rear spring
4 pop up, and distance becomes smaller between two column 1b, stablize frock 1, and frock 1 can stablize movement on three-level disk boss, drive probe
2, realize scanning.
4 quantity of spring in the present invention can be 6, and points 3 groups symmetrical to be set or 4 quantity of spring is 3 at equal intervals
It is a, at equal intervals on same column 1b.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should be covered by the protection scope of the present invention.
