Description
Technical field
This utility model is related to a kind of firing box partial structurtes air seal test frock.
Background technology
There is a cavity structure, cavity structure master with external cable coupling part in certain MISSILE LAUNCHING case tail end inside cable
To be made up of cable barrel and rectangular box.It is welded on the inside of cavity structure on firing box inside panel.Rectangular box in cavity structure
Outside weldings have the socket fixing seat of outer cable in connection, and rectangular box bottom is drilled with multiple osculums for excluding condensation.Send out
The cavity structure for penetrating case tail end is the entrance of rainwater when preventing from using, and between cavity structure and inside panel, level weld seam requirement is sealed,
Need to carry out the sealing that air seal test detects weld seam after the completion of cavity structure welding.Due to cavity structure exist it is multiple with it is outside
The hole of connection, and without special inflatable interface, it is therefore desirable to a set of frock dedicated for air seal test.
Utility model content
The purpose of this utility model is to provide a kind of firing box partial structurtes air seal test frock, for solving above-mentioned technology
Problem.The technical scheme for solving its technical problem is to provide a kind of firing box partial structurtes air seal test frock, including filling aerofluxuss
Component, top plate member, filling gas deflation assembly includes blanking cover, sealing ring, fills exhaust joint；Top plate member includes top board, corner block, double
Hook bolt；The exhaust joint center of filling is through hole, and one side head outside weldings are in the endoporus of blanking cover, there is provided fills aerofluxuss and leads to
Road；The sealing ring is then enclosed within the outside of the ring of blanking cover；The corner block side is equilateral triangle, outside its inclined-plane and firing box
The side laminating of rectangular tube diagonal bar, and can slide on diagonal bar；The side of corner block is drilled with tapped through hole, equipped with double in screwed hole
Hook bolt；One layer of vacuum leak hunting adhesive tape is stained with the top board, for blocking condensation leaking hole.
Preferably, four fastening bolts are carried on the blanking cover.
Preferably, the corner block side is fitted with the side of 45 ° of rectangular tube diagonal bars outside firing box using 45 ° of inclined-planes,
And can slide on diagonal bar.
Aviation plug sockets mouth can be carried out sealing and can providing filling aerofluxuss by this utility model using gas deflation assembly is filled
Interface.Top plate member then solves the problems, such as multiple condensation leaking hole sealing blockings during air seal test, and top plate member can be effective
After opposing inflation, the lower vacuum seal rubber belt of pressure effect internally is rushed to open the problem of gas leakage.Operation letter when this utility model is used
It is single, and do not change original firing box regional area structure.

Specific embodiment
It is understandable to enable above-mentioned purpose of the present utility model, feature and advantage to become apparent from, it is below in conjunction with the accompanying drawings and real
Apply example to be described in detail specific embodiment of the present utility model.
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, air seal test frock in firing box local of the present utility model, including：Fill aerofluxuss to connect
1, sealing ring 2, blanking cover 3, corner block 4, top board 5, stud 6.
It is through hole wherein to fill 1 center of exhaust joint, and one side head outside weldings are in the endoporus of blanking cover 3, there is provided fill row
Gas passage.Sealing ring 2 is then enclosed within the outside of the ring of blanking cover 3.Four fastening bolts are carried on blanking cover 3.Fill during use exhaust joint 1,
Sealing ring 2, blanking cover 3 are collectively constituted and fill gas deflation assembly, both for the closure to aviation plug base holes, are also provided for air seal test
Fill exhaust port.
4 side of corner block is equilateral triangle, and its 45 ° of inclined-planes are fitted with the side of 45 ° of rectangular tube diagonal bars outside firing box,
And can slide on diagonal bar.The side of corner block 4 is drilled with tapped through hole, and stud 6 is housed in screwed hole, back-outs double during use
Hook bolt, the other end of stud are withstood on 90 ° of side rectangular tubes of firing box.One layer of vacuum leak hunting adhesive tape is stained with top board 5,
For blocking condensation leaking hole.
When the frock is used, fix first with the bolt on blanking cover 3 and fill gas deflation assembly, then top board 5 is utilized into vacuum leak hunting
Adhesive tape bonding is on condensation leaking hole, and corner block 4 is placed between 45 ° of rectangular tube diagonal bars outside top board 5 and firing box, and twists
Go out stud 6, until top board 5 is held out against.It is last to connect on-off valve, flow meter from filling exhaust joint 1, and inflate inward, treat
Relevant pressure cutting-off valve is reached, closure nut of screwing on is opened valve, carries out air seal test.
Although this utility model is disclosed with preferred embodiment, which is not for limiting this utility model, Ren Heben
Art personnel are may be by the methods and techniques of the disclosure above in without departing from spirit and scope of the present utility model
Appearance makes possible variation and modification to technical solutions of the utility model, therefore, it is every without departing from technical solutions of the utility model
Content, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model,
Belong to the protection domain of technical solutions of the utility model.
