Description
Technical field
The utility model relates to the vibration testing device in the environmental mechanics test, the particularly support component of drive coil in the electric jigging platform moving coil--and parcel plate, this parcel plate are used for substituting the reel part on the existing moving coil framework.
Background technology
Electric vibration testing bench (hereinafter to be referred as motorized stage) is a kind of equipment that product or parts is carried out the vibration simulation test, can evaluate the resistance to shock of a product by test, for examining this product quality that rational basis is provided, therefore be widely used in industries such as space flight, aviation, boats and ships, automobile, electronics, communication, household electrical appliances and instrument and meter.
Motorized stage is utilized the electric and magnetic oscillation principle design, and its structure mainly is made up of several parts such as stage body, magnetic cylinder, field copper, moving-coil, hanger bearing guide piece and cooling devices.Basic functional principle is: the field copper that is placed in the magnetic cylinder feeds direct current generation stationary magnetic field, and the moving-coil that has work top and drive coil is connected with exchange current, and this moving-coil is arranged in the stationary magnetic field.Owing to interact between exchange current and the stationary magnetic field, the exciting force that generation one changes with size of current and direction promotes moving-coil and vibrates back and forth around the centre of oscillation.
In traditional motorized stage design assembling, because moving component (being moving-coil) will transmit very big exciting force, so very high rigidity and intensity must be arranged, simultaneously in order to guarantee that moving component has sufficiently high resonant frequency and takes into account economy, existing moving coil framework 5 (see figure 1)s are formed by aluminium alloy or magnesium alloy materials integrally casting usually, and the bottom has the metal reel 4 of wall cartridge type, be that metal reel 4 is structure as a whole with moving coil framework 5, metal reel 4 is the parts on the moving coil framework 5.Goodbye Fig. 1, drive coil 6 is wound on metal reel 4 peripheries, and drive coil 6 is bonded on the metal reel 4 with High temp. epoxy resins, and metal reel 4 is as the support component of drive coil 6, drive coil 6 is linked into an integrated entity, to improve the rigidity of drive coil 6.
The shortcoming of this kind structure is:
One, because prior art adopts aluminium or the moulding of magnesium integrally casting, also will be after the moulding through cut, so the wall thickness of metal reel 4 need design thicklyer, it is many to take up room, the space that just must reduce coiling for the thickness that guarantees the magnetic field air gap during design, opposite to guaranteeing that winding space just must increase the thickness of magnetic field air gap;
Two, prior art adopts aluminium or the moulding of magnesium integrally casting, and for reaching rigidity and being beneficial to cut, the wall thickness of metal reel 4 need design thicklyer, has increased the weight of moving-coil 7, has influenced the single order resonance frequency of moving-coil 7;
Three, because prior art metal reel 4 is that integral body processes, produce eddy current for avoiding metal reel 4, several grooves be must on metal reel 4, open, thereby the physical strength and the rigidity of metal reel 4 reduced;
Four, owing to do not have mesh on the prior art metal reel 4, be subjected to it to block the heat radiation that in the shaking table of forced air cooling formula, is unfavorable for moving-coil 7.
Between above shortcoming as can be known, existing wall cartridge type metal reel structural vibrations platform efficient with the moving-coil one is not high.
Summary of the invention
The utility model designs a kind of support component of novel drive coil--the parcel plate, replace existing reel with it, its objective is and satisfying under the constant situation of same rigidity, magnetic field width of air gap, increase the space of moving-coil coiling, improve the single order resonance frequency of moving-coil and the radiating efficiency of forced air cooling simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of perforate stainless steel moving-coil parcel plate, and wherein: this parcel plate is a tubular, is rolled into by corrosion resistant plate, is distributed with some through holes on the corrosion resistant plate plate face; This corrosion resistant plate and drive coil concentric are positioned at drive coil week or periphery, perhaps clamp between the inner ring winding and outer ring winding of drive coil; And this corrosion resistant plate drive coil is mutually bonding.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described through hole is uniform to be arranged on the corrosion resistant plate plate face.
2, in the such scheme, described corrosion resistant plate " clamps between the inner ring winding and outer ring winding of drive coil " and is meant that the drive coil coiling goes out inner ring and outer ring, and corrosion resistant plate is clipped between this inner ring and the outer ring.
The utility model design, principle of work are: the utility model parcel plate adopts stainless steel, offer some through holes on it and constitute mesh plate, replace existing reel structure with it, it is located at the interior week or the periphery of drive coil, or clamp between inner ring winding and outer ring winding, drive coil is supported, constitute a coil assembly independently with drive coil.Under equal quality, improve the rigidity of drive coil integral body, improved the reliability of moving-coil first order resonance frequency and moving-coil, increased air-cooled cooling effect.And the utility model parcel plate and moving coil framework become the branch body structure, have significantly reduced parts difficulty of processing and moving-coil technique for coiling difficulty.
Specifically can list following advantage:
1, because the utility model has adopted corrosion resistant plate, compares at the situation lower wall thickness that reaches equal rigidity with existing reel and can reduce, just increased winding space, make the more compact structure of moving-coil.
2, because perforate on the utility model parcel plate helps improving the radiating efficiency of forced air cooling type shaking table, and also be beneficial to High temp. epoxy resins drive coil, parcel plate and moving coil framework are better combined, improved the reliability of moving-coil.
3, become " supporting in the corrosion resistant plate ", " corrosion resistant plate outsourcing " and " embedding in the middle of the corrosion resistant plate " three kinds of forms by the existing single pattern of reel, embodiment is flexible, has made things convenient for enforcement.
4, owing to application of the present utility model, this reality is split with novel and moving coil framework, has improved the exploitativeness of technology from another point of view, is convenient to make.
