Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The present invention provides rigidity vibration isolators and vibrating isolation systems such as a kind of three axis of all-metal, can solve very high, very
Under low temperature environment and pollution environment the problem of reliably working, and have the axial same stiffness characteristic in three, space, solves vibration isolation dress
The problem of setting the properties vibration controls such as three axial directions.
As shown in Figure 1, vibration isolator of the invention includes connecting rod 1, sealing ring 2, shell 3, fastening screw 4, metal-rubber
Ring 5, metal-rubber piece 6, adjustment ring 7 and bottom plate 8；
Lid is equipped with circular opening on shell 3, and bottom is open；Connecting rod 1 is cone structure, the periphery of connecting rod 1
It is set with metal-rubber ring 5；The bottom surface of metal-rubber ring 5 is concordant with 1 big end bottom of connecting rod, and there are one section of uncoated gold for small end
Belong to rubber ring 5；The part of the uncoated metal-rubber ring 5 of 1 cone small end of connecting rod is pierced by from the circular opening of 3 upper cover of shell, gold
The top surface for belonging to rubber ring 5 is withstood on the inner wall of 3 upper cover of shell；Connecting rod 1 and metal-rubber ring 5 is arranged in metal-rubber piece 6
Bottom；Bottom plate 8 is from the bottom open that metal-rubber piece 6 was installed below and was fixed on shell 3；Wherein, 1 small end of connecting rod with
Gap between circular opening is provided with sealing ring 2；Adjustment ring 7 is housed on the outer circumference surface of metal-rubber piece 6.Shell 3 and bottom
Being correspondingly arranged on the outer surface of plate 8 has support lug structure, shell 3 and bottom plate 8 can be fixed together by fastening screw 4；
It is provided with mounting hole 11 on 8 bottom surface of bottom plate, for connecting device for vibration insutation load 10；1 upper end of connecting rod is provided with threaded hole 9,
It is used to connect with external devices.
The principle of full-metal vibration isolator of the invention is: metal-rubber ring 5 is sleeved on the outside of connecting rod 1, limits taper
Connecting rod 1 is mounted on connection Ei in lateral movement (limiting two freedom degrees of horizontal direction), using metal-rubber piece 6
Dry 1 bottom, limitation taper connection bar 1 is in axial movement (limiting the one degree of freedom in vertical direction), due to metal rubber
The elasticity of glue and the effect of friction energy-dissipating, vibration isolator axially and laterally all have the effect of rigidity and damping, pass through tune
The density of whole metal-rubber ring 5 and metal-rubber piece 6 can make rigidity axially and laterally, damping capacity almost the same, real
The rigidity such as existing three axis.Connecting rod 1 is designed to pyramidal structure by the present invention, can be limited it and be deviate from from the aperture of shell 1, together
When, upward effectiveness in vibration suppression can be enhanced.
Full-metal vibration isolator of the invention can be used in combination, and form vibrating isolation system, and usually used combination is shown in figure
2, four vibration isolators are one group, are divided to two opposite sides of two groups of device for vibration insutation load 10 for being separately mounted to need to be isolated vibration
On face；The vibrating isolation system of two groups of vibration isolators composition, can be vibration isolation again by the threaded hole 9 in the connecting rod 1 of each vibration isolator
Equipment load 10 is connected on carried matrix, and vibrating isolation system is formed the flexibility between device for vibration insutation load 10 and matrix even
It connects, effectively controls influence of the vibration environment to equipment.Since vibration isolator has three axis vibration isolating effects, therefore it may only be necessary in vibration isolation
Arrange that vibration isolator forms vibrating isolation system, does not need the cloth on other sides on the two of them opposite flank of equipment load 10
Vibration isolator is set, therefore, the present invention vibrating isolation system can be reduced using vibration isolator, and reach identical or better vibration isolation effect
Fruit.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
