Background technique
When the test of the aircraft big uncork test specimen airtight density of load, need to carry out effective sealing to big uncork test specimen and just can complete, aircraft big uncork test specimen mentioned here refers to opening diameter and is greater than 150 millimeters and be less than the test specimen of 300 millimeters.
At present, adopt maximum seal arrangements to be as shown in Figure 1, circular rubber mat plate and circular metal caul are installed respectively in test specimen both sides, then with four hold-down bolts, four of both sides pieces of backing plates are compressed.But such seal arrangement is heavier, the load diatibution of big uncork test specimen can be affected; Further, can move to surrounding when existing seal arrangement is installed, cause difficulty is installed; In addition, also need to smear sealer in hold-down bolt surrounding after existing seal arrangement installation and carry out secondary seal, increase cost and enhance labor intensity.
Model utility content
The utility model provides a kind of aircraft big uncork test specimen seal arrangement, and can solve current seal arrangement affects test specimen load diatibution, installs the problem of difficulty.
For achieving the above object, the utility model adopts following technological scheme:
A kind of aircraft big uncork test specimen seal arrangement, for sealing test specimen opening, comprising:
Double polarizing keys shape for hat part, have the first boss and second boss of cylindrical and coaxial setting, the diameter of described first boss is greater than described second boss, and the diameter of described second boss equals described test specimen opening diameter;
Lug boss, cylindrical and be coaxially arranged on the end face away from described first boss of described second boss, described lug boss offers screw thread;
Rubber washer, in ring, be set on described second boss, described rubber washer internal diameter is less than the diameter of described first boss;
Boss backing plate, in ring, the internal diameter of described boss backing plate equals the external diameter of described lug boss, and the external diameter of described boss backing plate is greater than the internal diameter of described rubber washer;
Gland nut, the screw thread of its internal thread and described lug boss matches.
Further, described first boss inside has the cylindrical and coaxial inner chamber arranged.
Further, described rubber washer comprises two, lays respectively at the both sides of described test specimen.
Further, the internal diameter of described rubber washer is greater than the diameter of described second boss.
Further, the external diameter of described rubber washer is greater than the diameter of described first boss.
The aircraft big uncork test specimen sealing device structure that the utility model provides is simple, when the airtight density of load test of aircraft big uncork test specimen, can seal the big uncork of test specimen; This seal arrangement is fixed by means of only a nut, and overall weight is alleviated, and lowers the impact of the load diatibution on test specimen; The diameter of the second boss equals the diameter of the big uncork of test specimen, moves when preventing seal arrangement from installing to surrounding, makes installation simpler; In addition, by the effect of rubber washer, gland nut place is sealed, do not need to smear sealer separately, reduce the cost.

Embodiment
Be described in detail of the present utility model below in conjunction with accompanying drawing.
As shown in Figures 1 to 7, aircraft big uncork test specimen seal arrangement of the present utility model comprises rubber washer 1, boss backing plate 2, double polarizing keys shape for hat part 3 and gland nut 4.
As shown in Figure 5, double polarizing keys shape for hat part 3 is a kind of components having two boss, and two boss are respectively cylindrical and coaxial the first boss 301 and the second boss 302 arranged.Further, the diameter that the diameter of the first boss 301 is greater than the second boss 302, second boss 302 equals the opening diameter of test specimen 5, moves when preventing seal arrangement from installing to surrounding, makes to install simpler.
First boss 301 boring, makes its inner inner chamber forming cylindrical and coaxial setting, overall weight is alleviated, lowers the impact of the load diatibution on test specimen.And the second boss 302 interior solid, the second boss 302 away from coaxial on the end face of the first boss 301 and be fixedly installed lug boss (303); Lug boss 303 is cylindrical, and diameter is less than the diameter of the second boss 302, and lug boss 303 external process has Full Thread FT.
The material of gland nut 4 can adopt Q235 steel, and the Full Thread FT external diameter of its minor diameter of thread and double polarizing keys shape for hat part 3 upper projecting portion 303 matches, and gland nut 4 can be screwed on lug boss 303.This seal arrangement to coordinate with a gland nut 4 by means of only a lug boss 303 and is fixed, and makes overall weight alleviate equally, lowers the impact of the load diatibution on test specimen 5.
As shown in Figure 4, rubber washer 1 is in ring, and internal diameter is less than the diameter of the first boss 301, and is be set on the second boss 302.Usual employing tetrachloroethylene rubber, thickness can be 10mm.The effect of rubber washer 1 is hoop sealing big uncork test specimen 5 and double polarizing keys shape for hat part 3, and such sealing means does not need to smear sealer separately, reduces the cost; During use, rubber washer 1 can comprise two, is arranged on the both sides of big uncork test specimen 5 respectively, makes sealing effect better.
Further, the internal diameter of rubber washer 1 can 5mm larger than the diameter of the second boss 302, and, the external diameter of rubber washer 1 can 5mm larger than the diameter of the first boss 301, and like this in the process of press seal, can inwardly wriggle in rubber washer 1 inner edge, outer rim can outwards be wriggled, centre can compress, and gauffer gas leak phenomenon can not occur, thus more effectively realizes the sealing of big uncork test specimen 5 hoop.
As shown in Figure 6, boss backing plate 2 is in ring, and internal diameter equals the external diameter of double polarizing keys shape for hat part 3 upper projecting portion 303, and the external diameter of boss backing plate 2 is greater than the internal diameter of rubber washer 1.The material of boss backing plate 2 can adopt Q235 steel, and its effect is the rubber washer 1 (rubber washer 1 near this side of lug boss 303) that is fixed and clamped.
Aircraft big uncork test specimen sealing device structure of the present utility model is simple, reliable performance, can when the airtight density of load test of aircraft big uncork test specimen, tight sealing is carried out to the big uncork of test specimen, air tight, and comparatively existing apparatus loss of weight more than 50%, lowers the impact of the load diatibution on test specimen.
When aircraft big uncork test specimen seal arrangement of the present utility model is installed, after a rubber washer 1 installed by the second boss 302 of double polarizing keys shape for hat part 3, its entirety is passed from test specimen 5 big uncork side and is arranged in big uncork; Then, from test specimen 5 big uncork opposite side, another rubber washer 1 is arranged on the second boss 302 of double polarizing keys shape for hat part 3; Then at the lug boss 303 upper mounting boss backing plate 2 of double polarizing keys shape for hat part 3, and compression is fixed with gland nut 4, to complete the installation of seal arrangement.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
