Technical field
The high-cycle fatigue detection technique field of flexible piece is the utility model is related to, it is more particularly to a kind of to be based on high-frequency electrical magnetic-type
Vibrator.
Background technology
Electromagnetic actuator is a kind of vibrator using electromagnetic force as exciting force, and part or machine are realized by electromagnet apparatus
The periodic motion of the stabilization of structure, or it is supplied to a certain size stress of part.Fatigue test using such a energisation mode as excitation
Machine is electromagnetic type HF fatigue testing machine, due to its fast response time, frequency height, excellent in efficiency, energy-conserving and environment-protective, this kind of type it is tired
Labor testing machine has a wide range of applications in engineering practice.
Various types of fatigue tester application scenarios are different, the widely used testing machine type in engineering practice
For electromagnetic drive type and electro-hydraulic servo formula.The characteristics of electromagnetic type HF fatigue testing machine is due to its running high frequency, can shorten examination
The test period of part, energy consumption is reduced, save manpower, while in control aspect also outstanding performance, it is possible to achieve high control essence
Degree, Shape fidelity is high, quick action response can be achieved, for big rigid metal test specimen, this kind of testing machine is good choosing.
Though electro-hydraulic servo formula fatigue tester can realize the fatigue test of materials under big load, Larger Dynamic displacement, its
Achievable working frequency is relatively low, causes test period to be grown, and oil pressure, oil temperature also can produce interference to the waveform of output, influences
Machine performance is also because of the complicated, not easy to clean of electro-hydraulic servo formula fatigue tester with safeguarding, therefore it is applied in engineering
Degree in practice does not have electromagnetic type fatigue tester extensive.
Due to existing vibrator, big electromagnetic attraction can not be produced greatly when air gap becomes, thus it is big in order to realize
Dynamic displacement, it is very helpful to develop a kind of fatigue test of the vibrator that can realize Larger Dynamic displacement to flexible piece
's.
The electromagnetic type fatigue tester in engineering practice, it is difficult to for the big test specimen of the deflection during experiment
The fatigue properties analysis of experiments of tension and compression stress alternation under room temperature state.
The content of the invention
The utility model provides a kind of high-frequency electrical magnetic-type vibrator, and to solve for during experiment, deflection is big
The problem of test specimen is difficult under room temperature state, the fatigue properties analysis of experiments of tension and compression stress alternation.
The utility model adopts the technical scheme that：Counterweight is fixedly connected with supporting plate by screw, and upper end cover passes through spiral shell
Bolt is fixedly connected with counterweight, and coil is wrapped on coil rack, and fixed core is fixedly connected with upper end cover, dynamic iron core and spacing bottom plate
It is fixedly connected, spacing bottom plate is fixedly connected with tray substrate, and fixed core and dynamic iron core are located in coil rack, has gas between them
Gap, housing is enclosed on outside coil rack and both ends are fixedly connected with upper end cover, bottom end cover respectively, both ends of the spring respectively with branch
Fagging is fixedly connected with tray substrate.
Described dynamic iron core is formed using silicon steel plate packing, and using boss, platform, bottom uses T-type structure for upper end.
Described fixed core is formed using silicon steel plate packing, and bottom is using concave station, platform, the upper end shape with dynamic iron core
Into complementation.
Described coil rack uses polytetrafluoroethylene (PTFE).
The coil is with enamel-covered wire winding method coiling, and place mat highland barley paper is to insulate between layers.
The spring is double square leaf spring, the side being engaged using two pieces of rectangular slabs at both ends with bolt with mass
Formula connects.
The utility model has the advantages that structure is novel, by being T-type structure by the structure design of dynamic iron core so that electromagnet
Sufficiently large, repeated action electromagnetic attraction can be provided, and make structure more simple, due to electromagnetic attraction size with
The size of air gap has direct relation, and air gap is bigger, and electromagnetic attraction is smaller, due to that can provide big electromagnetic attraction, just means
Big air gap requirements can be met by, when vibrator can provide sufficiently large air gap, it is intended that fatigue tester can be with
Fatigue detecting is carried out to flexible test specimen, adds the use range of fatigue experimental machine.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the spring profile of the utility model double square harden structure.
Embodiment
Counterweight 1 is fixedly connected with supporting plate 3 by screw, and upper end cover 2 is fixedly connected by bolt with counterweight 1, and coil 5 twines
It is wound on coil rack 6, fixed core 7 is fixedly connected with upper end cover 2, and dynamic iron core 8 is fixedly connected with spacing bottom plate 10, spacing bottom plate
10 are fixedly connected with tray substrate 12, and fixed core and dynamic iron core are located in coil rack, have air gap between them, housing 4 is enclosed on
Outside coil rack and both ends are fixedly connected with upper end cover, bottom end cover 9 respectively, the both ends of spring 11 respectively with supporting plate 3 and support
Plate 12 of trying to get to the heart of a matter is fixedly connected；
Described dynamic iron core is formed using silicon steel plate packing, and using boss, platform, bottom uses T-type structure for upper end；
Described fixed core 7 is formed using silicon steel plate packing, and bottom is using concave station, platform, the upper end with dynamic iron core 8
Formed complementary；
Described coil rack 6 uses polytetrafluoroethylene (PTFE)；
The coil 5 is with enamel-covered wire winding method coiling, and place mat highland barley paper is to insulate between layers；
The spring 11 is double square leaf spring, is engaged using two pieces of rectangular slabs at both ends with bolt with mass
Mode connects.
After carcasing, by coil with enamel-covered wire winding method coiling, place mat highland barley paper is with exhausted between layers
Edge；In order to realize that the change of multistage exciting force controls, by the different number of turn windings of coil point, leave " entering " and " go out " the end of a thread, can be achieved
The series connection of coil turn, drawn to observe the situation of coil and coil radiating, winding wiring, port is left on housing；
After coil 5 is by alternating current, electromagnet can be alternately produced suction, be that dynamic iron core 8 is being inhaled when there is suction to produce
Power effect is lower to move, and after suction disappears, initial position is returned under the elastic force of spring, so forms the excitation of vibration.
