Detailed description of the invention
Describe the present invention below in conjunction with the accompanying drawings.
The present invention passes through vibration test, and simulation is by guided missile, propelled at high velocity jet plane and rocket engine device
Produce more distinctive site environment, with checking vibration to ceramic body, vitreous body, pin or ceramic body with
Whether the sealing between vitreous body causes defect or damage.
The present invention passes through impact test, simulates in handling, transport or execute-in-place due to unexpected stress or fortune
The impact that dynamic state changes suddenly and produces, such impact may destruction work characteristic or cause similar
In the damage caused because vibration is too strong, if shock pulse is repeated, then damage more serious.
The present invention has especially simulated the vibration of 60G～80G high-magnitude, 3000G impact test, to overcome at present
A difficult problem in existing jig Design, the specific scheme is that
As shown in Figures 1 to 3, a kind of ccd image sensor vibration, impact apparatus, including chuck body
1 and cover plate 3, chuck body 1 is cube structure, and each is embedded structure, arranges on each face
There is the sample putting hole 2 placing ccd image sensor, by test of many times, the sample of each is placed
When hole 2 thickness is set to 0.6cm～1.3cm, in vibration impact experiment, it is ensured that enough in the case of rigidity,
Make fixture the lightest.
Sample putting hole 2 axial symmetry on each or centrosymmetry, to prevent ccd image sensor from shaking
Resonance is produced during Dong；Specifically, cover plate 3 can be arranged or each one to one with sample putting hole 2
The sample putting hole in face is all covered by a cover plate.
Having pin fixing hole on sample putting hole 2, pin fixing hole is designed as blind hole or through hole, with
The ccd image sensor of pin can be inserted in the pin fixing hole of chuck body 1；Pin and pin fixing hole
For matched in clearance, experiment proves that, when fit clearance is defined as 0.2mm～0.5mm, can effectively prevent
Pin is caused damage by vibration or impact process.
As shown in Figures 4 and 5, cover plate 3 can be covered on sample putting hole on 2, and cover plate 3 is provided with plane rank
Ladder structure, coordinates (such as figure with the glass planar of ccd image sensor and the hierarchic structure of ceramic flat surface composition
Shown in 6～7), cover plate 3 is connected with chuck body 1 to compress the CCD figure being placed on sample putting hole on 2
As sensor, impulsive force is made to be evenly distributed to each plane of ccd image sensor, it is ensured that in vibration, punching
The glass cover-plate not fragmentation because of ABNORMAL STRESS when hitting test.
Chuck body 1 and cover plate 3 are same metal material, preferably aluminium alloy, prevent ccd image sensor
And produce electrostatic between chuck body 1 and cover plate 3, ccd image sensor is caused damage.
Six faces of cube structure surround hollow structure, it is achieved the space upset of chuck body, to complete
The vibration of 60G～80G high-magnitude, 3000G impact test.Gold, silver are placed on the sample putting hole 2 of each
Or aluminum slice, rigidly fix with chuck body 1 realizing ccd image sensor, and uniform stressed.
When cover plate 3 compresses the ccd image sensor being placed on sample putting hole on 2, cover plate 3 is less than sample
The height of putting hole 2.
During test, first ccd image sensor is inserted in pin fixing hole, cover cover plate, make CCD scheme
As the biplane of sensor agrees with double stress surfaces of cover plate, then that cover plate is solid by screw with chuck body
Fixed.
Being proved by the result in actual tests, this fixture design approach disclosure satisfy that aerospace ccd image
Sensor carries out vibrating, the requirement of impact test.Being easily worked in machining, precision is easily protected simultaneously
Card, operation is few, low cost.
The content not being described in detail in description of the invention belongs to the known technology of those skilled in the art.
