Abstract
A loading and bracing structure of a totally air-tight table body for an electric vibrating table is characterized in that the parts arranged at the peripheral region of the electric vibrating table body (1) are closely connected. The top of the table body (1) has flexible and tight coupling with the surface of a moving coil working table (2). So an air-tight chamber (4) is formed in the inner space of the table body. The air-tight chamber (4) is provided with a charging port connected with air supply, which forms air pressure support to the surface of the moving coil working table (2), thus forming the loading and bracing structure of the totally air-tight table body. The table body of the utility model is air tight, so the inner chamber of the table body is an air chamber. The bottom of the working table is almost supported by the air pressure, thus increasing effective area supported by air and greatly increasing loading and bearing force. The inner air pressure of the table body is isolated from outer air pressure and the normal operation of the electric vibrating table is not affected when four-combined table surface is under pressure, so the loading and bracing structure of the totally air-tight table body is suitable for four-combined tests.
Description
Technical field
The utility model relates to the electric vibration testing device in the environmental mechanics test, being specifically related to the load support structure in the electric vibration testing bench. this load support structure is specially adapted to high thrust, heavy load, four comprehensive electric vibration tables, and load support efficiently is provided.
Background technology
Electric vibration testing bench (hereinafter to be referred as electric vibration table) is a kind of equipment that product or parts is carried out the vibration simulation test, can evaluate the anti-seismic performance of a product by such test, for examining this product quality that rational basis is provided, therefore now be widely used in industries such as space flight, aviation, boats and ships, automobile, electronics, communication, household electrical appliances and instrument and meter.
Electric vibration table utilizes the electric and magnetic oscillation principle design to form, its structure (as Fig. 1) is mainly by stage body 11 (comprising the magnetic cylinder), field coil 12, moving-coil 13, Guiding wheel structure 14,15 and air spring 16 etc. are formed up and down, stage body 11 generally by magnetic cylinder ring 17, central magnetic pole 18, on cover 19 and end cover 20 constitute.Here air spring 16 is load support devices, it is arranged on moving-coil 14 times, is used for test specimen (promptly negative cutting) on the support works table top, along with the thrust of electric vibration testing bench is increasing, and the weight of test specimen is more and more heavier, and the volume of air spring also increases accordingly.But need because of electric vibration table designs, the locus that air spring can be installed is limited, and the increase of load sometimes just must increase design difficulty and production cost of products by outer support system; In addition, when electric vibration testing bench was done four compbined tests (pressure, temperature, humidity and vibration test), the moving-coil of electric vibrating was worked under the situation of negative pressure, and traditional air spring supporting construction just can't be played a supporting role to load.For this reason, designing a kind of novel load support structure is one of major issue of paying close attention to of those skilled in the art.
Summary of the invention
The utility model is not enough for high thrust, heavy load shaking table anchorage force for solving prior art, sometimes must be by outer support system design difficulty and cost height, and the technical matters that can't be applicable to four compbined tests, provide a kind of novel electric vibration table complete airtight stage body load support structure.
For achieving the above object, the technical solution adopted in the utility model is: the complete airtight stage body load support structure of a kind of electric vibration table, be tightly connected between each parts of the periphery of electric vibration table stage body, flexible sealing is connected between stage body top and moving-coil work top, make the entire inner space of stage body become a sealed gas chamber with this, this sealed gas chamber is provided with inflation inlet and connects source of the gas, work top is formed air pressure support, and constitutes complete airtight stage body load support structure with this.
In the such scheme, described " being tightly connected between each parts of the periphery of electric vibration table stage body " is meant between each parts that constitutes the stage body periphery and is tightly connected; When stage body periphery parts are by magnetic cylinder ring, last cover and play cover to constitute, just magnetic cylinder ring top and last cover can be tightly connected through O-ring seal, also be tightly connected between magnetic cylinder ring bottom and following cover through O-ring seal, be tightly connected with the sealing and dustproof film between cover and work top and go up, make the stage body entire inner space become an air chamber with this.
Design concept of the present utility model is: the original structure that utilizes shaking table, improve the sealing between stage body periphery parts, make whole stage body inner chamber become an atmospheric air chamber, replace original air spring that work top is supported, increase the load capacity of electric vibration table.
The anchorage force F=Δ PS of the utility model air chamber
Δ P----air chamber internal pressure and air pressure difference;
S----effective gas Area of bearing;
The whole lower surface of the utility model moving-coil substantially all is subjected to air pressure to support formation available gas Area of bearing S, and it is much larger than the support useful area of existing air spring, so the utility model has improved anchorage force greatly under the situation of identical pressure differential.
And the utility model is because of adopting the stage body airtight construction, and stage body air pressure inside and external pressure are isolated, can be used for doing four compbined tests with this, negative pressure on the work top when doing four compbined tests, and keep former air chamber pressure under the work top in the stage body, keep support to load.
Because the application of technique scheme, the utility model compared with prior art has the following advantages:
1, because stage body of the present utility model seals, and the whole inner chamber of stage body becomes air chamber, the bottom of work top is supported by air pressure substantially all, has increased the effective gas Area of bearing, has increased load support power greatly;
2, because the utility model stage body seals, and stage body air pressure inside and external pressure are isolated, are doing the operate as normal that does not influence electric vibration table under the four comprehensive table top negative pressure conditions, therefore be applicable to four compbined tests;
3, because the utility model can be given up original air spring, reduce the effective mass of moving-coil relatively, improved frequency of operation.
