Description
Technical field
The invention belongs to X-ray Testing Technology field.Determine more particularly to one kind for deep camber hollow blade ray detection
Position device.
Background technology
The manufacturing technology of hollow blade improves constantly inner-cavity structure and also become increasingly complex in recent years, and the curvature of blade is also more next
It is bigger.During casting hollow blade, ceramic core is used, after blade cast, core is removed using chemical reaction, formed in blade
Portion's cavity.But when blade depoling is incomplete, remains in core in blade cavity and block cooling duct, residual core can be with high temperature
Blade chemically reacts, and triggers aircraft safety accident.Check the method for remaining core mainly using filling metal dust at present
Method, improve its contrast.But for the hollow blade of deep camber, when carrying out ray detection, caused because vane curvature is larger
Image blocks, and can not differentiate the quality of blade inner chamber.For the inspection of the residual core of deep camber hollow blade, consider detected
Blade construction feature, manufacture and design a kind of device for the positioning of deep camber blade ray detection, realize to hollow blade transillumination
The accurate fast positioning of angle, make image of the blade inner chamber on egative film is parallel to be independently distributed, exclude blade inner chamber and mutually block pair
Influence caused by testing result, the contrast of film image is improved, so as to ensure to detect quality.
The content of the invention
In order to solve above-mentioned technical problem, the invention provides one kind to be used for deep camber hollow blade ray detection
Positioner.The residual core of deep camber casting hollow blade, which can be realized, can effectively detect, detect positioning solidification, improve detection quality,
Ensure the safety of engine.
The technical solution adopted by the present invention is as follows：
One kind of the invention is used for deep camber hollow blade ray detection positioner, including bearing, locating piece and spacing
Pin, the locating piece are two, and bare terminal end is symmetrically placed on bearing, and the bearing has the type face of two different angles, bearing
One end in the angled end of type face between two locating pieces is provided with spacer pin, and clamping end face and the blade tenon of two locating pieces coordinate
Connect.
Further, the amphitypy face is parallel with blade cavity axis difference, and the type face containing blade cavity axis is vertical
Face and blade cavity are non-intersect.
Beneficial effects of the present invention：
The present invention can accurate fast positioning blade ray detection angle, prevent blade inner-cavity structure mutually blocks from influenceing bottom
Piece is imaged, and strengthens image contrast, ensures detection quality.So the inspection of the residual core of deep camber hollow blade inner, is technology hair
The needs of exhibition, immeasurable social benefit will be brought.

Fig. 3 is present invention blade schematic diagram to be detected.
In figure：1. bearing, 2. locating pieces I, 3. locating pieces II, 4. spacer pins, 5. straight pins, 6. screws, 7. blades, 701-
708 be blade cavity, and 8. type faces I, 9. type faces II, L is axis.
Embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples：
Embodiment：As shown in Figure 1-Figure 3, the present invention includes bearing 1, locating piece I 2, locating piece II 3 and spacer pin 4, described
Locating piece I 2, the bare terminal end of locating piece II 3 are symmetrically placed on bearing 1, pass through straight pin 5 and hexagon socket cap head screw 6 respectively
Fix, type face of the bearing 1 with two different angles, in the type face angled end of bearing 1 between two locating pieces I 2, locating piece II 3
One end be provided with spacer pin 4, the clamping end face of two locating pieces coordinates with blade tenon to connect.
As shown in Fig. 2 the type face I 8, type face II 9 are parallel with blade cavity axis L difference, contain blade cavity axis L
Type face vertical plane M and any cavity of blade it is non-intersect.Type face I 8 is used for detecting 701,702 cavities of blade, and type face II 9 is used for
Detect the 703-708 cavities of blade.
The detection method of the present invention：
1) blade inner-cavity structure, cavity distribution situation are determined.The core and blade transverse cross sectional used according to blade
Part, determine structure and the distribution of blade interior cavity.
2) the residual core radiological survey X best orientation of blade is determined.Typical blade is chosen, according to the distribution of blade interior cavity,
Enable blade bore passages parallel with beam.Because blade interior is complicated, it is necessary to which multiple azimuth distributions are carried out with true
Protect all cavities and obtain optimal transillumination angle.
3) best orientation and blade tenon shape determined according to above step designs and produces clamping and positioning device.Should
Device can position twice ensures that whole cavities are parallel with the beam of vertical incidence, and imaging effect is good, and image contrast is high, does not have
There is the image interfered with each other.Positioning method is using frock support type face and detection platform angle fixed form, clamping form foundation
Locating piece fixture that blade tenon shape is designed, support type face as needed with locating piece fixture is angled ensures leaf
Piece internal passage is parallel with beam.
When in use, the present invention is placed on the lower section of X-ray machine X, i.e., in effective transillumination area, blade 7 is mounted in into the He of locating piece I 2
Between locating piece II 3, and carried out by alignment pin 4 spacing, prevent from sliding.The type face I 8 of bearing 1 is positioned over detection down first
On platform, constant bearing is selected according to the location type face I 8 of the distribution of blade leading edge cavity and bearing 1, indulges blade leading edge cavity
It is parallel with beam to face, sensitivity of film is carried out, each cavity in blade inner chamber can be obtained on egative film and is independently clearly projected, is realized
Inspection to blade leading edge inner chamber quality.The type face II 9 of bearing 1 is positioned in detection platform down again, according to blade air inlet
The location type face II 9 of side cavity distribution and bearing 1 selects constant bearing, makes blade leading edge cavity longitudinal direction and is put down with beam
OK, sensitivity of film is carried out, each cavity in blade inner chamber can be obtained on egative film and is independently clearly projected, is realized to the other inner chambers of blade
The inspection of quality.By the detection of different directions twice, the inspection of all inner chamber quality of whole blade is realized.
