Bright and its feature, profile and advantage will become more apparent.The identical mark in whole accompanying drawings
Note instruction identical part.Accompanying drawing can not be drawn to scale, it is preferred that emphasis is this hair is shown
Bright purport.
Fig. 1 is the cross-sectional view of novel air vibration isolator of the present invention;
Fig. 2 is the rearview of novel air vibration isolator of the present invention.
Embodiment
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings, but not
Restriction as the present invention.
Vibration damping is carried out to low frequency and ultralow frequency to realize, improves existing equipment vibration environment,
Manufacture machining accuracy and accuracy etc. are improved, the invention provides a kind of novel air vibration isolator,
The air vibration isolator has the relatively low natural frequency of vibration, higher vibration isolating effect and reasonably can resistance trimming
Buddhist nun, after high level of accuracy controller can make product working depth of the present invention stable under any load
Keep constant, can also make the present invention that there is different working depths under same load, adapt to more
The limited requirement of multipair mounting structure, greatly improves product qualified rate and efficiency of assembling.
Specifically as depicted in figs. 1 and 2, novel air vibration isolator of the present invention includes:
Base 1, it is provided with some enhancing muscle 2, in an embodiment of the present invention, the wherein bottom
Seat 1 is a semienclosed cavity, i.e., is set with an open top, the enhancing muscle
In the bottom position of the cavity.
Dividing plate 4, be arranged among the base 1, for closing the base 1, it is described every
The closing space of plate 4 and the base 1 composition forms dampening chamber 5;I.e. in the embodiment of the present invention
In, dividing plate 4 sets in the base and is located at its base top opening lower position, therefore dividing plate
A dampening chamber 5 is constituted with the closing space of base composition.
Diaphragm 6, it is arranged on the dividing plate, for the part bottom on enclosed baffle
Seat, the diaphragm 6 form negative with the closing space that the dividing plate 4 and part base 1 form
Carry room 7;I.e. in embodiments of the present invention, diaphragm 6 is arranged on base and is located at its base top
Portion's aperture position, closing opening, therefore diaphragm 6, which are located on dividing plate, to be set;Wherein diaphragm 6
The closing space formed with part base 1, dividing plate 4 constitutes a load cell 7.
Top cover 8, it is arranged on diaphragm 6, and is also set up between the top cover and the base
There is horizontal controller 9;
Wherein, dampening chamber 5 and load cell 7 pass through the phase of a flow speed control valve 10 that is arranged on base
It is intercommunicated, it is possible to achieve damping is adjustable.
In an embodiment of the present invention, the novel air vibration isolator is additionally provided with a trim ring
11, the trim ring is mainly disposed between diaphragm 6 and the top cover 8, as formation load cell 7
A part.
In an embodiment of the present invention, a safety valve is additionally provided with the outside of dampening chamber
12, the movable plunger of the safety valve 12 is connected with top cover with steel wire rope, when top cover is supported room
When interior gas jacks up too high, pulling on the movable plunger of safety valve makes the gas in dampening chamber straight
Run in and be put into air, prevent because vibration isolator inside because hypertonia cause shock insulation it is unstable and
Diaphragm damages.
In an embodiment of the present invention, the air vibration isolator is generally as an air chamber, shape
Into a memory space, load and be supported for top cover, wherein the present invention in diaphragm it is effective
The pressure of area and load cell decides the load capacity of this air vibration isolator, and can be by water
Flat controller 9 controls the working depth of air vibration isolator.
Because the dampening chamber of air vibration isolator is to separate and connected by flow speed control valve 10 with load cell
, therefore the design goes for different shapes, because indoor total capacity (available capacity)
Determine this product the natural frequency of vibration (when pressure is directly proportional to load, when load changes, from
Vibration frequency can also keep constant).Dampening chamber for prevent the transient vibration caused by interference and
The amplitude of limitation is quite important, and dampening chamber can effectively reduce vibration width when vibration isolator resonates
Degree.
In summary, the invention provides a kind of novel air vibration isolator, air vibration isolator tool
There are the relatively low natural frequency of vibration, higher vibration isolating effect and rational adjustable damping, high level of accuracy
Controller can make to keep constant after product working depth of the present invention is stable under any load, also may be used
