Top cover, it is arranged on the diaphragm, and is also set up between the top cover and the base There is horizontal controller;
Wherein, the dampening chamber and the load cell pass through the speed governing that is arranged on the base Valve is interconnected.
Preferably, above-mentioned novel air vibration isolator, it is characterised in that the novel air Vibration isolator also includes trim ring, and the trim ring is arranged between the diaphragm and the top cover.
Preferably, above-mentioned novel air vibration isolator, it is characterised in that in the base also It is provided with some enhancing muscle.
Above-mentioned technical proposal has the following advantages that or beneficial effect:
The invention discloses a kind of novel air vibration isolator, the air vibration isolator have it is relatively low from Vibration frequency, higher vibration isolating effect and rational adjustable damping, high level of accuracy controller can make Keep constant after product working depth of the present invention is stable under any load, the present invention is existed There is different working depths under same load, adapt to the requirement being more limited to mounting structure, Greatly improve product qualified rate and efficiency of assembling.
Brief description of the drawings
By reading the detailed description made with reference to the following drawings to non-limiting example, this hair 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 Make the present invention that to there is different working depths under same load, adaptation more to mounting structure by The requirement of limit, greatly improves product qualified rate and efficiency of assembling.
