It is equipped with multiple springs 3 between the upper plate 1 and lower plate 2, damping unit, the damping unit packet are equipped in the spring 3
The supporting sleeve 5 for including the lower plunger 4 for being vertically set on 1 bottom surface of upper plate and being vertically set on 2 top surface of lower plate, the supporting sleeve 5
Interior filling damping agent, the lower plunger 4 are inserted into damping agent and float up and down with the vibration of upper plate 1.Above and below spring 3
Both ends are equipped with rubber pad 6, for the insulating effect between upper plate 1 and lower plate 2, while playing the role of part damping.
Damping agent is a kind of colloid, the problem of rebound immediately after being compressed for release spring 3, reduces by 3 restoring force of spring
Momentum.The main component of existing damping agent is polysiloxanes, lubricant, pump oil, activating agent etc., and performance characteristics are sticky
Degree is high, and high and low temperature resistance is good, refractoriness, durability, oil resistance are good.Existing also a kind of damping agent is a kind of macromolecule
Polymer makees base-material by polyurethane, the high damping materials such as addition glass fibre, mica powder, graphite powder, then add fire retardant etc. its
His adjuvant etc..The type of damping agent is corresponding with the own wt of equipment on vibration isolator is placed on according to the use environment of vibration isolator
Adjustment, the component and content of the damping agent need voluntarily to match according to actual condition.However damping device is arranged in bullet
It in spring 3, solves damping device and is corresponded with spring 3, the momentum of whole springs 3 is alleviated in dispersion, can prevent because damping is set
It is susceptible to unbalance stress, unstable problem for concentrating, and reduces machining accuracy.
The top open part of the supporting sleeve 5 is equipped with the yielding rubber lid 7 for closure, in the yielding rubber lid 7
The through-hole passed through for lower plunger 4 is equipped at the heart, the bottom of the yielding rubber lid 7 is equipped with annular protrusion 8, the annular protrusion 8
Lateral wall be equipped with external screw thread, the inside top of the supporting sleeve 5 is equipped with and the matched internal thread of external screw thread.Yielding rubber
Lid 7 is used to block the gap between lower plunger 4 and supporting sleeve 5, and the damping agent being pasted onto on lower plunger 4 is scraped.Lower plunger 4 from
Through-hole passes through, and fits with yielding rubber lid 7, connection is threadably secured between yielding rubber lid 7 and supporting sleeve 5, under making
Frictional force between inserted link 4 and yielding rubber lid 7, can be real much smaller than the friction torsion between yielding rubber lid 7 and supporting sleeve 5
Now strike off the damping agent being pasted onto on lower plunger 4.
The yielding rubber lid 7 is surrounded by the flanging 9 bent downward, is received inwardly for balancing damping serum cap 7
Pull power, this is pullled power and is converted by yielding rubber lid 7 and the frictional force of lower plunger 4, and the steady of yielding rubber lid 7 can be improved
Solidity, while having the function of protecting 5 opening of supporting sleeve.
The bottom of the annular protrusion 8 be equipped with interior high outer bottom annular tiltler 10, for guide the damping agent struck off to
The surrounding of annular protrusion 8 guides, and falls off convenient for the concentration of damping agent, prevent damping agent the dispersion of the bottom surface of annular protrusion 8 without
The problem of being easily detached from annular protrusion 8.
The top plate is equipped with the first rubber sleeve 11 extended downwardly, and the bottom plate is equipped with and 11 phase of the first rubber sleeve
Second rubber sleeve 12 of fitting, the first rubber sleeve 11 and the second rubber sleeve 12 protect vibration isolation for preventing external particle object from entering
Equipment inside platform, and inner air and outer air and moisture circulation can be closed, delay air-drying for damping agent, while can be used for barrier top
Electric current transmission on plate and bottom plate.First rubber sleeve 11 is arranged in the outside of the second rubber sleeve 12, due to external particle object
By meeting after the first rubber sleeve 11 and the blocking of the second rubber sleeve 12 to whereabouts, if underlying second rubber sleeve 12 is located at outside,
The particulate matter that the first rubber sleeve 11 being then located above stops can enter from the gap of the two in vibration isolation table.
First rubber sleeve 11 slopes inwardly, and inclined angle is no more than 45 °, so that most of dust is passed through inclined-plane and arrives
On second rubber sleeve 12, the dust fall amount of the first rubber sleeve 11 can be reduced, improves dust-break effect.
The bottom of the lower plate 2 is equipped with rubber cushion blocks 13 corresponding with spring 3, in vibration isolation table by downward effect
When power, rubber cushion blocks 13 can reduce the Oscillation Amplitude of vibration isolation table itself, and neutralizing the micro- of spring 3 shakes, and increases the vibration isolation of vibration isolation table
Effect improves the stability of vibration isolation table work.
Rubber cushion blocks 13 can be divided into natural rubber and synthetic rubber two major classes by material.Natural rubber is in the comprehensive of physical mechanical
It is advantageous to close aspect of performance, and synthetic rubber is then in certain properties, such as oil resistant, ageing-resistant, acid and alkali-resistance, resistance to ozone, resistance to height
Temperature etc. is more prominent, can need to select it according to specific use, to improve the effect of rubber cushion blocks 13.Rubber
There are many connection types of cushion block 13 and bottom plate, such as：By way of bonding by the connection of rubber vibration insulating pad and bottom plate or
Rubber cushion blocks 13 can also be fixedly connected with bottom plate.
The fastening bolt 14 of the upper plate 1 and lower plate 2 being surrounded by for adjusting precompression, fastening bolt 14
Upper and lower ends extend through upper plate 1 and lower plate 2, and are fixed by nut, if desired increase the precompression of vibration isolation table, adjustable
Save the distance between the nut of side, the upper lower nut of shortenings, realization shortening the distance between the side upper plate 1 and lower plate 2.
It is equipped with equilibristat mounting bracket 15 at the surrounding center of the upper plate 1, for installing equilibristat, in installation process
In for debug vibration isolation table surrounding whether be in equilibrium state, to judge vibration isolation table table top whether be in horizontality, if
Imbalance by way of adjusting fastening screw or replacing spring 3, can realize that the table top balance of vibration isolation table, debugging are simple, straight
It sees, efficiently, detachable equilibristat after the completion of adjusting, can be installed again wait needing the when of adjusting.
Finally it should be noted that：Above-described each embodiment is merely to illustrate the technical solution of the utility model, rather than
It is limited；Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art
It should be understood that：It can still modify to the technical solution recorded in previous embodiment, or to which part or whole
