Abstract
It the utility model is related to a kind of external becket root attachment structure of refractory ceramics structure radome.Becket is wrapped in antenna house root, is evenly equipped with screwed hole on becket and antenna house link position periphery, the corresponding position of antenna house is provided with hole；Screw is installed, screw is deep into the hole on antenna house in the screwed hole of becket.The rigidity of link can be increased, reduce the connection stress in ceramic nose cone so that the stress in nose cone is reduced to alap level.
Description
Technical field
A kind of refractory ceramics structure radome of external becket is the utility model is related to, more particularly to antenna house is external
Becket root attachment structure.
Background technology
At present, high temperature guided missile cover is all connected using the cover body of high temperature ceramic material composition with metal connection ring by being glued
Formed, the structure of this form, in guided missile cover structure of the guided missile capouch portion no more than 500 DEG C, bonding load can be undertaken, but
It is in the guided missile cover for reach 1200 DEG C for head, root bonding pad hull-skin temperature can reach 900 DEG C, in internal surface temperature
Surface temperature can reach 400 DEG C.The transmission force property of glue sticking disappears, and causes ceramic nose cone deformation excessive, causes ceramic nose cone
Local compression between connection ring destroys.
The content of the invention
The purpose of this utility model：A kind of external gold of antenna house that reliability is high, is easy to Project Realization that is connected is provided
Belong to ring root attachment structure.
The technical solution of the utility model：A kind of external becket root attachment structure of refractory ceramics structure radome,
It is characterized in that：Becket is wrapped in antenna house root, and screwed hole is evenly equipped with becket and antenna house link position periphery,
The corresponding position of antenna house is provided with hole；
Screw is installed, screw is deep into the hole on antenna house in the screwed hole of becket.
Preferably, the hole that the corresponding position of described antenna house is set is through hole.
Preferably, the through hole other end development length that screw is deep on antenna house is not more than 1mm.
Preferably, the screw of selection is M6 types, and the internal diameter in hole is 6.5mm on antenna house.
Preferably, becket on antenna house link position periphery with being evenly equipped with 12 screwed holes.
Preferably, fluid sealant is scribbled between becket and antenna house.
Preferably, described antenna house is high temperature ceramic material.
The beneficial effects of the utility model：The rigidity of link can be increased, reduce the connection stress in ceramic nose cone so that
Stress in nose cone is reduced to alap level；Sealant is no longer undertaken binding function, only undertake sealing function.Drop
The difficulty of low antenna house development, in the past, substantial amounts of quiet heat integration experiment is needed in the development of antenna house, glue-line is adjusted by testing
Thickness, connection width and correlation the thickness at local ceramic joining position and the thickness of connection ring.And external becket root
Portion connecting structure has bigger design tolerance, for given structure, has very big design margin.
Brief description of the drawings
Fig. 1 is antenna house exploded view；
Fig. 2 is connecting portion bitmap after antenna house assembling.
Embodiment
As illustrated in fig. 1 and 2, sealant, the screw hole of ceramic nose cone 1 will be smeared on the connecting portion 2 of ceramic nose cone 1 first
Do not smear sealant in position 3；Sealant is smeared in the connection surface 5 of connection ring 4, the hole position 6 of connection ring 4 does not smear sealant；Will
Ceramic nose cone 1 and connection ring 4 are assembled according to corresponding hole position；Applied inside ceramic head taper hole 3 and the corresponding hole position of connection annular distance 6
Smear sealant；Attachment screw 7 is screwed in the screw hole of connection ring；After connection, from ceramic nose cone inner surface apertures position screw periphery 8
Smear sealant；Guided missile cover assembly after connection is dried, is sealant cures.
