It is an object of the invention to：In order to which the volume for solving existing anti-seismic detection instrument is excessive, structure excessively complexity is not
The problem of suitable for the miniature precisions instrument such as measuring instrument, the present invention provide a kind of vibration test device.
The present invention specifically uses following technical scheme to achieve the goals above：
A kind of vibration test device, including rack, driven member, driving mechanism, the driven member are positioned in rack
End, the driven member are connect with rack lower end, and the lower part of the driving mechanism and driven member is coordinated by gear；The master
Motivation structure includes spur rack, multilayer shock ring, vertical rod, push cylinder and slide bar, and the lower surface of the spur rack is provided with more
Layer shock ring, the multilayer shock ring are located at the top of vertical rod, and the vertical rod connect with slide bar and as the sliding block of slide bar,
The piston rod of the vertical rod and push cylinder connects；The driven member includes bumper, vibrations gear, the vibrations gear
It is connect with the lower surface of bumper, the bumper is placed and frame upper end.
Further, it is provided with buffer layer on the contact surface of the rack and bumper.
Further, the both sides of the bumper are provided with multipair flexible wear auxiliary wheel.
Further, the buffer layer in the rack is provided with groove corresponding with bumper auxiliary wheel.
Further, the section of the vibrations gear is half elliptic.
Further, the vibrations gear is made with straight-tooth band by alloy carburizing steel.
Beneficial effects of the present invention are as follows：
1, under high speed vibration, whole device can acutely shake and can be caused repeatedly to rack and driving mechanism bumper
Impact, after long-time, the case where rack etc. will appear deformation, the service life of very big shortening device and to increase safety hidden
Suffer from.The present invention is to avoid the occurrence of the situation of above-mentioned imagination, and buffer layer, bumper are provided on the contact surface of rack and bumper
Both sides be provided with multipair flexible wear auxiliary wheel, have on buffer layer to the corresponding groove of auxiliary wheel, and spur rack and vertical rod
Between be provided with multilayer shock ring.By multistage damping, buffering structure, bumper is in high speed dither process to whole device
The extra impact generated will be absorbed.Therefore the present invention has continual and steady, and using more long lifespan, security performance is stronger excellent
Point.
2, in traditional anti-seismic detection device, realize that vibrations need to realize with complicated structure, vibrations of the invention are
The section realized by shaking gear, and shake gear is half elliptic.The adjusting of the shockproofness of the present invention is by straight-tooth
The movement velocity of band is determined with move distance.It is specially that straight-tooth band movement velocity is faster, and velocity of vibration is faster；Straight-tooth band
Move distance is bigger, and vibration amplitude is bigger.In the vibrations of high intensity, vibrations gear is directly acutely rushed with straight-tooth band
It hits, after prolonged work, vibrations gear will substantially shorten with straight-tooth tape lifetime to be more easy to crumble.So the vibrations gear of the present invention
With straight-tooth band all using have surface it is hard and wear-resisting, good core toughness and impact-resistant alloy carburizing steel is made.To sum up institute
It states, the advantages of present invention is adjustable with shockproofness, and core component is more resistant to impact wear.
