Whole height.
Compressed air is through levelling valve air inlet spring, when rising taste on a vibration table to adjustment height, air bullet
Spring is constantly inflated, and when shake table is raised to adjustment height, levelling valve becomes cut-out source of the gas, and air spring inflation stops；When by
When duration expansion being compressed in air spring or other reasonses cause shake table higher than adjustment height, compressed air therein can be through
Cross levelling valve to be vented slowly automatically, decline table top, and when outer load increase or unbalance loading cause whole table top or a certain angle
When certain altitude drops in subordinate, it can automatically open up again in scope small above and below all or the corner levelling valve in dynamic flat
Weighing apparatus state, because shake table is three-dimensional vibrating, is flexibly connected, mounting height control valve so levelling valve is used with shake table
Afterwards, the pressure size of air spring compressed air can change with the change of load, make the shock-absorbing capacity of air spring and have
Changed.
Motor uses dither motor, carries out three-dimensional vibrating consolidation to shake table, 6 motors are divided into three groups, by micro-
Processor is controlled to direction of motor rotation, so as to realize the operating and vibration in three directions；Motor amplitude be 0.5 ~
1.5mm, time of vibration is in 3 ~ 4min.
Air spring can play dual parts of lifting vibration and buffer, and not only be not required to separately set lifting device, and may be used also
The requirement of cushioning effect can be vertically and horizontally played to meet, in addition, the size for adjusting its internal inflation pressure can also
Enough change the rigidity of spring, to adapt to the change of the different load below maximum Payload, it is ensured that the stabilization of vibration parameters；
Air spring also has simple in construction, and stable working, noise is small, the advantages of long lifespan.
The utility model, by the vibration of three different directions of motor, realizes sand by setting bicavate air spring
The enough degree of packing of case, this structure is simple in construction, and stable working, noise is small.
