Description
Technical field
The present invention relates to a kind of vibration isolator, in particular to the composite junction that is combined with wire mesh of a kind of electronic equipment rubber
Structure vibration isolator.
Background technique
In order to improve the measurement accuracy, control precision and safety and reliability of optoelectronic device, airplane equipment is for ring
The limitation of border vibration requires to be increasingly stringenter；And with the raising of the speeds of service such as aircraft, vehicle so that structural environment vibrates
Magnitude it is increasing, driving frequency to low-frequency range extend.By theory of vibration isolation it is found that if the rigidity of vibration isolator is lower, vibration isolation effect
Rate is higher, and low frequency vibration isolation effect is also better.Therefore, to the vibration control precision of raising optoelectronic device, it is necessary to reduce airborne light
The frequency of electric equipment vibration damping installation.
Existing wire mesh vibration isolator and rubber shock absorber all have the characteristic of three-dimensional vibration isolation, how free can be realized equipment
Spend the requirement of vibration control.But they are generally used just for a certain equipment development, and intrinsic frequency is difficult to accomplish
10Hz or less.Therefore, for certain aircraft requirements lower than 10Hz low frequency vibration isolation below use current vibration isolator incapability for
Power.It would therefore be highly desirable to design novel low frequency vibration isolation device for airborne opto-electronic device low frequency vibration isolation application field.
Summary of the invention
Present invention solves the technical problem that: it provides a kind of suitable for various electronic, the high vibration isolator of vibration isolation efficiency.
Technical solution of the present invention: the vibration isolator includes shell 1, transition core 2, rubber block 4, installation core 5, wire
Gauze pad 7, spring 8 and bottom plate 9, spring 8 are located on the bottom plate 9 of shell 1, and the inside of spring 8 is filled with wire gauze pad 7, spring 8
On be placed with transition core 2, the outside of 2 lower section spring 8 of transition core is filled with wire gauze pad 7；
Cavity is had in transition core 2, rubber block 4 is installed in cavity, installation core 5 is fixed on rubber block 4, in shell 1
Wire gauze pad 7 is filled between transition core 2.
As a kind of improvement of the technical program, core 5 is installed and is fixed as one by vulcanization with rubber block 4.The program is solid
Determine that effect is good, falling off for installation core can be prevented.
As a kind of improvement of the technical program, concave surface is provided on the outer surface of rubber block 4.This is designed as rubber block 4
Deformation provides space, improves the effect of vibration isolation.
Beneficial effects of the present invention: the vibration isolator structure is simple, convenient for assembly.By transition core by rubber block and wire
It is isolated into upper layer and lower layer between net and spring, the second level Vibration Absorbing System Design for realizing vibration isolator can be facilitated.The vibration isolator has lower
Rigidity, the vibration condition required suitable for low frequency vibration isolation.And vibration isolator still has the ability of three-dimensional vibration isolation, is applicable to three-dimensional
The equipment that vibration isolation requires.Rubber bodies have it is compact-sized, the changeable advantage of shape can easily change the knot of rubber core
Structure easily designs more multi-form vibration isolator.This composite construction vibration isolator has the frictional damping between wire mesh simultaneously, also
The hysteretic damping for having rubber macromolecular chain to generate in deformation process increases the damping characteristic of vibration isolator.

Specific embodiment
The technical program is described in further detail with reference to the accompanying drawing.
The vibration isolator includes shell 1, transition core 2, baffle 3, rubber block 4, installation core 5, threaded cap 6, wire mesh
Pad 7, spring 8 and bottom plate 9, spring 8 are located on the bottom plate 9 of shell 1, and the inside of spring 8 is filled with wire gauze pad 7, on spring 8
It is placed with transition core 2, the outside of 2 lower section spring 8 of transition core is filled with wire gauze pad 7；
Cavity is had in transition core 2, rubber block 4 is installed, the upper end of cavity has internal screw thread, with threaded cap 6 in cavity
External screw thread cooperate for fixing rubber block 4.It is fixed with installation core 5 on rubber block 4, is filled between shell 1 and transition core 2
Wire gauze pad 7 designs baffle 3, has the function of sealing metal mesh pad 7 between wire gauze pad 7 and shell 1.Rubber block 4
Outer surface on be provided with concave surface, which, which is equivalent to, provides the scope of freedom for rubber block 4, and the deformation for rubber block 4 provides sky
Between, increase the effect of vibration isolation.
1 enclosed inside of shell 4 three kinds of wire gauze pad 7, spring 8 and rubber block elastomers, can effectively realize vibration
Dynamic isolation.Rubber block 4 and wire gauze pad 7 and spring 8 are separated into upper layer and lower layer by transition core 2, constitute the knot of two grad vibration isolation
Structure.According to spring tandem principle, this structure can reduce the rigidity of vibration isolator, to reduce the intrinsic frequency of vibration isolator.It adopts
Rubber block 4 is vulcanized with rubber curing techniques and constitutes rubber core on installation core 5, what which can be convenient is installed to transition core
In 2, second level vibration insulation structure is formed.The shape flexible design of rubber and have the advantages that small in size, can be designed to a variety of
Shape.
