Abstract
This utility model relates to a kind of vibration table surface and is connected special fastener with sensor, including screw rod connection dish, right flank integral middle at screw rod connection dish is shaped with the standard M8 table top screw rod of the vibration table surface screw that spins, connect at screw rod and face left the centre of side and surrounding is formed respectively with five different screws in aperture, the sensor that spinning coordinates with screw respectively in the screw that five apertures are different is connected screw rod, and, the different screw in described five apertures is respectively standard M4, standard M5, standard M6, standard M7 and the screw of standard M8, the degree of depth of described each screw is the twice in respective screw aperture respectively, and, connect at each sensor and be installed with anti-loosening pad respectively on screw rod.This utility model can connect fastening vibration table surface and major part model sensor, still can have and preferably connect effect under the conditions of complicated operating condition of test and long weariness working.
Description
Technical field
This utility model belongs to vibrating sensor Calibration Technology field, particularly a kind of vibration table surface be connected with sensor special tightly
Firmware.
Background technology
The vibration table of vibration experiment produces vibrational system signal generator, is changed into machinery through the signal of telecommunication amplified
Move and pass to test specimen.Vibration experiment is for testing electronic product or the assembly mechanically and electrically sub-feature under dynamic stress.
User can test vibration resonance frequency, dependability and the fatigue strength of their product.Electromagnetic vibration platform can be simulated
All types of vibration tests, including sinusoidal fixed frequency and frequency sweep, random vibration and impact test.
And test specimen sensor and vibration table surface are all attached by screw, both screw standards are different, not of uniform size, it is difficult to
Find suitable securing member that both are attached.During routine use, both are bondd by many use Apis cerana Fabriciuss, bonding
Rear reliability is poor, is not only inconvenient to test, and adversely affects the result of test.
And vibration experiment typically requires sensor sizable to quantity and tests, it is desirable to convenient disassembly answered by sensor, with
Time, part fatigue test needs long-play vibration table, also requires that sensor can connect reliably within the longer time.Cause
This needs a kind of convenience, stable connection vibration table surface and the securing member of sensor.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and propose a kind of vibration table surface be connected with sensor special tightly
Firmware.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of vibration table surface is connected special fastener with sensor, including screw rod connection dish, in the right flank of screw rod connection dish
Portion is integrally shaped with the standard M8 table top screw rod of the vibration table surface screw that spins, and connects centre and the surrounding difference of side of facing left at screw rod
Being shaped with five different screws in aperture, the sensor that spinning coordinates with screw respectively in the screw that five apertures are different is connected screw rod.
And, the different screw in described five apertures is respectively standard M4, standard M5, standard M6, standard M7 and standard M8
Screw, the degree of depth of described each screw is the twice in respective screw aperture respectively.
And, connect at each sensor and be installed with anti-loosening pad respectively on screw rod.
Advantage of the present utility model and good effect be:
This utility model can connect fastening vibration table surface and major part model sensor, at complicated operating condition of test and for a long time
Still can have under the conditions of weariness working and preferably connect effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A direction view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model embodiment is further described: it is emphasized that the present embodiment is illustrative,
Rather than determinate, every other embodiment drawn according to the technical solution of the utility model by those skilled in the art,
Also belong to the scope of this utility model protection.
A kind of vibration table surface is connected special fastener with sensor, as it is shown in figure 1, include screw rod connection dish 3, at screw rod even
The right flank integral middle of flange is shaped with the standard M8 table top screw rod 4 of the vibration table surface screw that spins, and connects, at screw rod, side of facing left
Centre and surrounding be formed respectively with five different screws in aperture 2, in the screw that five apertures are different, spinning is joined with screw respectively
The sensor closed connects screw rod 1.
In of the present utility model being embodied as, the different screw in described five apertures is respectively standard M4, standard M5, standard
The screw of M6, standard M7 and standard M8, the degree of depth of described each screw is the twice in screw aperture respectively, only works as screw hole depth
Reach the twice in screw aperture or above time, spinning screw rod in screw just will not loosen in for a long time vibrations experiment.
In of the present utility model being embodied as, loosen on screw rod connection dish, at each sensor for preventing sensor from connecting screw rod
Connect the difference anti-loosening pad of spinning 5 on screw rod.
