Description
Technical field
The utility model relates to vibration test and uses the electric vibrating field, particularly the clearance dust guard on the electric vibration table.This dust guard is installed between shaking table upper end stage body and the moving-coil, and the clearance upper end closed is played dustproof effect.
Background technology
Electric vibration table is as main vibration test and dynamic characteristic test instrument, but the actual condition of simulation test sample, the structural strength of examination product, find the initial failure of product, therefore be widely used in industries such as national defence, space flight, aviation, communication, electronics, automobile, motorcycle, household electrical appliances.
Mainly form on the electric vibration table structure by several parts such as stage body, magnetic cylinder, field copper, moving-coil, bearing guiding device and cooling devices.Owing between moving-coil and stage body (comprising magnetic cylinder and central magnetic pole), have the clearance, this upper end, clearance is opened wide, in real work, each parts of shaking table are installed, the installation of test specimen and in the vibration test process, foreign material such as screw, nut, sensor are very easily fallen into above-mentioned clearance, and moving-coil with these article friction and collision takes place when dither, make moving-coil produce stuck phenomenon, shaking table is damaged.And, fall into article and the friction of moving-coil and the destruction that collision also causes the moving coil winding external insulation easily of clearance, moving coil winding very easily produces short circuit with stage body or other conductor, all will produce catastrophic consequence to moving-coil parts, pilot system itself and testing crew.How to avoid this phenomenon, addressing this problem is exactly the emphasis of this patent research.
Summary of the invention
The utility model opens wide for solving the upper end, clearance that exists in the prior art, in the real work foreign material easily fall into and can cause in the clearance that moving-coil is stuck, the problem of adverse consequencess such as damage and short circuit, a kind of shaking table dust guard is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of shaking table dust guard, comprise the dustproof film of rubber of an annular, and be provided with at least one circle portion that arches upward around annular center on the dustproof film of this rubber; The neighboring of the dustproof film of rubber is along last uniform screw mounting hole, and the dustproof film neighboring of rubber is along riding in the electric vibration table stage body upper end along last, on it again pressing trim ring is arranged, fixedly connected with stage body with the screw mounting hole of screw on trim ring, the dustproof film of rubber; The dustproof film inner edge of the corresponding rubber of electric jigging platform moving coil upper end outer peripheral face offers caulking groove, and the dustproof film inner edge inlay card clip in the caulking groove of moving-coil of described rubber is fixed, and is connected between moving-coil and the stage body upper end closed with the clearance with the dustproof symphysis of this rubber.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the portion of arching upward that " is provided with at least one circle portion that arches upward around annular center on the dustproof film of this rubber " wherein is meant the bend that dustproof film body arches upward and brought up or down, respectively but the portion's of arching upward crooked total length that arches upward has promptly determined dustproof film inner edge of rubber and outer intermarginal stretch range vertically, and therefore the best is that the portion's of arching upward total length diametrically need be slightly larger than shaking table half-peak shift value.
2, in the such scheme, for the inner edge of dustproof film can embed in the caulking groove, the dustproof film internal diameter of ring-shaped rubber just should be equal to or less than the diameter at moving-coil upper embedded groove bottom land place, optimal period is the diameter that the internal diameter of the dustproof film of described ring-shaped rubber is slightly less than moving-coil upper embedded groove bottom land place, need when installing like this with the dustproof center membrane hole of ring-shaped rubber strut the caulking groove place that is enclosed within moving-coil make dustproof film inner edge tightly clip on moving-coil, produce phenomenon when avoiding working inadequately because of tension force.
3, in the such scheme, can be provided with spherical convex tendon on the dustproof film inner edge of described rubber, this sphere convex tendon embeds in the caulking groove and is rotatably assorted with caulking groove.In the shaking table work, along with the relative stage body motion of moving-coil, spherical convex tendon also can rotate slightly relative to caulking groove, reduces the stress concentration point on the dustproof film of rubber, prolongs the serviceable life of the dustproof film of rubber.Here " spherical convex tendon " is with the dustproof inwardly protruded cylindrical muscle of film inner edge of rubber.
4, in the such scheme, described " trim ring " effect is that screw is increased the fastening contact area of the dustproof film of rubber, and general trim ring should adopt material such as the metal material with certain rigidity, makes the pressure distribution of the dustproof film of rubber more even.
5, in the such scheme, described " stage body " is meant the fixing part such as the relative moving-coil that is made of magnetic cylinder, central magnetic pole and case etc. in the electric vibrating, the dustproof film outer rim of rubber is to fixedly connected with this stage body, and general concrete should be to fixedly connected with the case in the stage body.
The utility model use principle is: the utility model adopts the dustproof symphysis of the rubber of an annular to be connected between moving-coil and the stage body, with the upper end covering sealing of clearance, plays dustproof, anti-foreign material and falls into the clearance.The dustproof film of described rubber is provided with the portion of arching upward, and inner edge and the outer intermarginal bigger degree of drawing that has in the axial direction are to satisfy the needs of the relative stage body amplitude of moving-coil on the shaking table.
Advantage of the present utility model has:
1, owing to the utility model seals the upper end covering of clearance with the dustproof film of rubber; realized protection to the clearance; can effectively block foreign material such as screw, nut, sensor even dust and fall into, avoid that moving-coil is stuck, the generation of adverse consequences such as damage and short circuit.
2, be with the dustproof film of rubber of the portion that arches upward owing to the utility model employing, the dustproof film inner edge of this rubber is in the axial direction having bigger degree of drawing with intermarginal outward, so the utility model is applicable to big displacement shaking table.
3, the clamping hoop type structure that adopts spherical convex tendon to cooperate owing to the dustproof film inner edge of the utility model rubber and the syndeton of moving-coil with caulking groove, in shaking table work, spherical convex tendon rotates in caulking groove, and it is big to connect mobility, the dustproof film of rubber is not fragile, easy for installation again.
