Technical field.
Background technology
Application of the push-button switch product in the fields such as aerospace and automobile, power electronics is very extensive.In order to right
Switch product is examined and is verified, to reach the working condition under fitting practical service environment, i.e., right under vibration
Button switch carries out the electrical endurance test of repeated push action.But related component producer is directed to traditional button press longevity
Life test device is tested in the case of simple stress, for example, split merely put row button press repeatability into
Test；Under vibration the normally-closed contact of switch and normally opened contact tremble breaking to tremble merely and closes test, and there is no exist
It is split under vibration environment to put row button pressing operations into, i.e., the longevity is not carried out in the case where vibration applies simultaneously with switch press
Order experimental test.Existing experimental rig can not be accomplished under vibration to realize switch the pressing of adjustable frequency, test
The performance parameter of gained switch is also inaccurate, and can not reflect the actual working condition of switch product.
Invention content
Exactly to provide a kind of machinery of vibration environment lower switch dynamic for situation and designing for the above-mentioned prior art by the present invention
The test device for making controllably to apply carries, and is loaded while the purpose is to realize that vibration is acted with switch press, it is ensured that shaking
Under rotating ring border, the superposition of switch mechanical action is realized so that product is more close to practical service environment, accelerates by laboratory
It tests and ensure that the resistance to environmental suitability of Switch product is horizontal to reflect the working condition of Switch product.
The purpose of the present invention is achieved through the following technical solutions：

Spring (11) forms it into Flexible Reset.
Also be fixedly mounted on pinboard (2) one for adjust test device entirety intrinsic frequency to avoid with shake table
(1) auxiliary stand (16) of resonance is formed.
Multiple cams (5) of the installation for improving testing efficiency in rotary shaft (4), equally, on holder (6) also installation with
The identical test specimen installs fixture (7) of cam (5) quantity simultaneously corresponds with cam (5) in position.
The structure of technical solution of the present invention includes two aspects, first, vibration mechine, can realize on vertical direction
Vibration, the other is switch mechanical action applying mechanism, makes the switch of test specimen 8 be in suitable by adjusting test specimen installs fixture 7
Position on, i.e., pressing axis 10 can be actuated with the rotation of cam 5 switch mechanical compression action.When 5 radius of cam is larger
Side rotation when idler wheel 14 being driven to roll, push pressing axis 10 to move along a straight line and press the switch of test specimen 8, at this time resetting spring
11 are compressed；When the smaller side rotation of 5 radius of cam drives idler wheel 14 to roll, resetting spring 11 is had an effect at this time, is made
Pressing axis 10 is obtained to return to original state.
The advantages of technical solution of the present invention is, functionally for, can under vibration to push-button switch into
Row mechanical compression, and reserve the lead terminal of switch, can vibration, the mechanical compression in the case of split row electric loading of putting into
Apply, realizes the simulation to switching real work state, test the actual life of the lifetime data obtained more Proximity switch；
On the other hand in performance for, the structure setting involved in the technical solution can be avoided effectively within the scope of test frequency
The resonance of switch press device and shake table, main realization method are that an auxiliary branch is installed on the pinboard of vibration table
Frame, auxiliary stand are rigidly connected with switch mechanical action applying mechanism by bolt and screw, and shape is variable, and shake table is controlled
The control at end is with sensor (realizing that the conditions such as vibration level for can bear to structure residing for sensor carry out control application), together
When more monitoring sensors can be placed in vibration table, switch mechanical action applies in structure, the examination needed for follow-up at this time
It tests in frequency range and carries out the frequency sweep test of different acceleration magnitudes (such as 1g, 5g, 10g etc.), according to shake table control terminal
Computer display waveform is judged, if having between switch mechanical action application structure and vibration table within the scope of test frequency
Resonance, then be adjusted the holder in structure, such as increases auxiliary stand, is acted to switching on and shutting down tool apply structure and vibration again
Table top is monitored, and then carries out vibration frequency sweep test, until again within the scope of test frequency, the two does not generate resonance.
The increase of auxiliary stand so that the resonance point that switch mechanical action applies between structure and vibration table is in test frequency range
Except, follow-up test will not be had an impact.
