Description
Technical field
The utility model is related to Engine Block Test technical fields, more particularly to aeroengine test instrument blanking cover.
Background technology
When aero-engine and gas turbine carry out special test, due to testing the difference of demand, partial test instrument
Table hole need using blanking cover block, but due to test stream field accuracy requirement, between the boss of instrument blanking cover and instrument hole
Fit clearance is smaller, therefore the instrument blanking cover near high-temperature component, and blocking under warming phenomenon often occurs with engine body, causes
Disassembling blocking cap is very difficult.
Existing aero-engine and gas turbine test instrumentation blanking cover smooth outer surface, the special-use puller of design operation simplicity
Technical difficulty is larger, after experiment, if blocking under warming occurs with engine body in it, very difficult, the generally use in dismounting
" one " word screwdriver and hammer percussion agitate or part to be tested is left office, and the mode tapped after decomposing from inside is dismantled, and when operating cost is taken
Power, in some instances it may even be possible to influence experiment progress and effect.
Utility model content
To overcome above-mentioned at least one defect existing in the prior art, the utility model provides aeroengine test instrument
Table blanking cover, the boss including pedestal and positioned at the pedestal one side；
Tapped blind hole is provided on the pedestal, one end of the tapped blind hole is stretched into the boss；
The pedestal is fixed on engine outer surface by fastener, and the boss stretches into the Meter Test of the engine
In hole, top surface is concordant with the inner flow passage of the engine.
Preferably, the one side with the boss of the pedestal is mounting surface, and the mounting surface is lozenges.
Preferably, the pedestal and the boss are integrally formed component.
Aeroengine test instrument blanking cover provided by the utility model, can be real by the design of puller connection screw thread hole
The fast quick-detach of existing aero-engine and gas turbine test instrumentation blanking cover after blocking under warming occurs with engine body, reduces and surveys
It tries instrument disassembling blocking cap difficulty, save the operating time, improve operating efficiency, reduce the test period.

Specific embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Attached drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the utility model.
It should be noted that：In the accompanying drawings, from beginning to end same or similar label represent same or similar element or
There is same or like element.Described embodiment is the utility model part of the embodiment rather than whole
Embodiment, in the case where there is no conflict, the feature in embodiment and embodiment in the application can be mutually combined.Based on this reality
With the embodiment in new, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
In the description of the utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instructions such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on attached drawing institutes
The orientation or position relationship shown is for only for ease of description the utility model and simplifies description rather than instruction or imply signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that this practicality
The limitation of novel protected scope.
Herein, " schematic " expression " serving as example, example or explanation " should not will be described herein as " showing
Any diagram, the embodiment of meaning property " are construed to a kind of preferred or more advantageous technical solution.
As shown in Figures 1 and 2, the utility model provides aeroengine test instrument blanking cover, including pedestal 10 and position
Boss 20 in 10 one side of pedestal.
Tapped blind hole 30 is provided on pedestal 10, one end of tapped blind hole 30 is stretched into boss 20.
Pedestal 10 is fixed on engine outer surface by fastener, and boss 20 is stretched into the Meter Test hole of engine,
Top surface is concordant with the inner flow passage of engine, ensures that engine interior flow field is undisturbed.
The one side with boss 20 of pedestal 10 is mounting surface 11, and mounting surface 11 is lozenges.
In the present embodiment, pedestal 10 and boss 20 are integrally formed component.
After blocking under warming occurs for instrument blanking cover and engine body, puller is screwed into tapped blind hole 30, by screw thread by
Power extracts instrument blanking cover, also wedge tool can be used to shovel into mounting surface 11 while extracting, and is puller power-assisted, realizes that instrument is blocked up
Cover fast quick-detach.
The above is only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, in the technical scope that any one skilled in the art discloses in the utility model, the change that can readily occur in
Change or replace, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with described
Subject to scope of the claims.
