Electric vibration table is by fixing magnetic field and is arranged in the shaking table that the vibration force that interaction produced that this magnetic field is connected with the coil of certain alternating current drives.Its basic structure mainly is made up of stage body (magnetic cylinder ring, magnetic cylinder cap, magnetic cylinder bottom), field copper, moving-coil, bearing guiding device, driving circuit, cooling device, gudgeon air spring isolation mounting, bearing etc.Stage body is a cylindrical member, field copper be fixed in the stage body tube circumferentially, moving-coil is arranged in the field copper and by bearing guiding device and is connected with stage body, stage body passes through gudgeon air spring isolation mounting seat again on bearing.During work, field copper feeds direct current and produces the stationary magnetic field, the moving-coil that has work top and drive coil is connected with exchange current and produces alternating magnetic field, when the moving-coil that produces alternating magnetic field is arranged in the stage body that produces the stationary magnetic field, because the magnetic field interphase interaction, produce certain exciting force table top that pushes the work forward and vibrate back and forth along axis direction.
When carrying out vibration test, test specimen is fixed on the table top of electric jigging platform moving coil, then the performance of testing test specimen by the vibration of vibration stage body.This class testing is owing to consider measuring accuracy, factors such as test safety require the edge of test specimen can not exceed the outer rim of electric jigging platform moving coil table top, therefore can only test the small size test specimen that some are no more than moving-coil table top scope, if want the big test specimen of test volume, a bigger expansion table top of area generally need be installed on the table top of moving-coil enlarge test specimen ground erection space, but because the center of gravity of test specimen often not necessarily is positioned on the geometric center of moving-coil table top, therefore can bring bigger unbalance loading moment, high-frequency at electric vibration table, the vibration of hard intensity can cause the generation of test failure or other accident down, therefore how to improve the anti-bias load ability of expansion table top, making the expansion table top can steady operation be the prior art technical issues that need to address.
Summary of the invention
The utility model is to improve electric vibration table to expand table top anti-bias load ability, make expansion table top steady operation, and a kind of electric vibration table expansion table top auxiliary support structure is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electric vibration table expansion table top auxiliary support structure, this structure comprises at least two bracing or strutting arrangements, and these bracing or strutting arrangements are uniform and be supported between expansion table top and stage body or the bearing around electric vibration table stage body center; Described bracing or strutting arrangement comprises a housing, housing is fixed on stage body or the bearing, and the housing inner bottom part is provided with air bag, and the air bag top is provided with the guidepost that vertically relative housing is slidingly connected, fixedlying connected with the air bag top in the guidepost lower end, fixedlys connected with expansion table top bottom in the guidepost upper end; Air bag in described each bracing or strutting arrangement interconnects.
Related content in the technique scheme is explained as follows:
1, in the such scheme, establishes linear bearing between described guidepost and housing.
2, in the such scheme, described linear bearing is fixed on the housing by shaft block ring.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
1, because the utility model supports the expansion table top by several bracing or strutting arrangements are set, satisfied the testing requirements of some larger volumes, irregular center of gravity test specimen, enlarged the usable range of electric vibration table, improved the ability to bear of stage body eccentric moment, made it possess bigger anti-bias load moment capacity.
2, because the utility model guidepost supports by air bag and air bag between each other by tracheae UNICOM, guaranteed that effectively the anchorage force of guidepost equates, and had the effect of damping, shock-absorbing, guaranteed the working stability of expansion table top.
