Description
Technical field
The utility model belongs to target seeker cabin structure design field, is related to a kind of connection structure, leads more particularly to one kind
Leader cabin member mounting connection structure.
Background technique
Target seeker cabin is mounted on projectile nose, target seeker cabin mainly install sensor and servo rotating mechanism etc. it is accurate at
Part.In guided missile supersonic flight, target seeker cabin will bear the operating conditions such as high temperature, high pressure, shock and vibration, overload.In order to drop
Low pneumatic heat transfer enters inside cabin on member, reduces from head entering signal dissipation of energy, target seeker cabin uses ceramics
Material radome fairing.
At work, target seeker cabin requires ceramic radome fairing to connect with metal shell reliably, internal member connection structure and
Metal shell connection is reliable.When ceramic radome fairing and when metal shell is cementing or soldering connection, for primary assembly forming, do not have
Repeat dismounting function.Based on the connection type, it is unable to prepared screw-bolt hole on ceramic radome fairing, makes member and metal shell in front end
Connection, internal member can only be connect in member rear end face with metal shell by bolt, and the member of the connection type is in stress shape
At cantilever beam force structure in formula.When member bears vibration, impact, overloading load, in load transmission to metal shell end face.
Summary of the invention
The purpose of the present invention: a kind of target seeker cabin member mounting connection structure is proposed, in order to various tight
Under cruel working condition, member one end is bolted, and one end is connected more reliable by being press-connected.
Technical solution of the present invention:
A kind of target seeker cabin member mounting connection structure, including ceramic radome fairing 1, metal shell 2, member 5, end face connection
Screw 8, the ceramics radome fairing 1 are mounted on outside metal shell 2, and positive stop lug boss, member 5 are equipped on the inside of 2 rear end face of metal shell
It is put into metal shell 2 from 2 rear end face of metal shell, the tail portion of member 5 is contacted with positive stop lug boss, and is pressed by attachment screw 8
It fastens.
There are an inclined-plane boss in a kind of target seeker cabin member mounting connection structure, 2 front end of metal shell, it is described at
There is small―gap suture between the head and inclined-plane boss of part 5.
A kind of target seeker cabin member mounting connection structure, further includes insulating rubber 3 and sponge rubber plate 4, described
Sponge rubber plate 4 is being circular layout outside 5 head of member, and the insulating rubber 3 is circular layout outside sponge rubber plate 4, described
Insulating rubber 3 is contacted with the inclined-plane boss of 2 front end of metal shell, and the insulating rubber 3 and sponge rubber plate 4 are by member 5 and gold
Belong to the extrusion deformation of the inclined-plane boss of 2 front end of shell.
A kind of target seeker cabin member mounting connection structure, 4 thickness ratio of insulating rubber 3 and sponge rubber plate
It is designed in decrement ratio, deflection is proportional to compressing force linear.
Advantages of the present invention: the utility model is easy to operate, facilitates operation, can Fast Installation member to designated position, it is real
Ready-made part is reliably installed, and member cantilever beam force structure is eliminated.
Detailed description of the invention:
Fig. 1 is attachment structure schematic diagram before assembling；
1 ceramic radome fairing, 2 metal shells, 3 insulating rubbers, 4 sponge rubbers, 5 members；
Fig. 2 is attachment structure schematic diagram after assembly；
Insulating rubber after 6 compressions, sponge rubber after 7 compressions, 8 end face attachment screws.
Specific embodiment:
The invention will be described in further detail with reference to the accompanying drawing.
The utility model is referring to Fig. 1-Fig. 2, and a kind of target seeker cabin member mounting connection structure is by ceramic radome fairing 1, metal
Shell 2, insulating rubber 3, sponge rubber plate 4, member 5, end face attachment screw 8 form.
Metal shell 2 is in the front end that member 5 is installed, and the front end of member 5 is for pyramidal structure, and processing dimension can not mention
Required precision is guaranteed by the insulating rubber 3 and sponge rubber plate 4 of compression.
There are sponge rubber 4 and insulating rubber 3 to design between member 5 and metal shell 2, rubber thickness is according to proportion of deformation
It being designed with heat insulation, sponge rubber 4 and insulating rubber 3 are pre-installed on member one end, by other end Bolt Tightening Force,
Double-layer rubber is compressed, is deformed in linear deformation stage.
Insulating rubber 3 and 4 thickness of sponge rubber plate are designed in decrement ratio.
Insulating rubber 3 and sponge rubber plate 4 to different-thickness carry out compression test, measuring force and deformation displacement number respectively
According to.To insulating rubber 3 relatively and under 4 power load same state of sponge rubber plate, the deflection of insulating rubber 3 is sponge rubber plate
1/5 or so of 4, and for 2mm sponge rubber in deflection within the scope of 0mm-0.6mm, deflection and compressing force are in ratio line
Property.For the sponge rubber 4 of 3mm or more thickness within the scope of the deflection of 1/2 thickness, deflection is proportional to compressing force linear.
On insulating rubber 3 and 4 thickness of sponge rubber plate installation member 5, it is flat to be less than metal shell 2 for radial overall size after installation
Straight section size.
The utility model is easy to operate, facilitates operation, can Fast Installation member to designated position.When installation, by member 5 from
One laterally inner side of the opening of metal shell 2 pushes, and is pushed to insulating rubber 3 and is in contact with metal shell 2.
Adjustment member 5 posture so that its end face attachment screw position is matched with 2 screw hole location of metal shell, firmly to
Inside pushes member 5, after member 5 is installed in place, installs end face attachment screw 8.
When end face attachment screw 8 is installed, in any symmetrical two screw precessions metal shell, 2 screw hole, then remaining is twisted
Screw finally screws screw.
