Power resets by spring 5 after removing, and the quantity of elastic probe 7 sets according to the quantity of product P IN pin
Fixed, cylinder 18 head is to be connected with probe frock bar 6 by draw-in groove 19.At test product
During, along with mechanism for testing installing plate moves down, first elastic probe 7 touches the PIN of product
Pin, can not move owing to product is integrally fixed in fixture, and then elastic probe 7 is by compression one
Fixed amount；Along with the increase of decrement, cylinder mounting plate 3, cylinder 18 and probe frock bar 6
Being come by jack-up all along guide pillar 4, now spring 5 is also compressed, and so can ensure that will not be by
Damage was caused, it can also be ensured that elastic probe 7 head and product P IN in declining multipair product
Pin good contact, it is achieved the reliable test of electrical property；Described mechanism for testing installing plate 1 is provided with
Mechanism for testing 102 quantity can be set according to actual needs, the most described test
2 mechanism for testing 102 can be provided with on mechanism's installing plate 1, to improve testing efficiency, figure of the present invention
Situation shown in 1 is exactly that described mechanism for testing installing plate 1 is provided with the concrete feelings of 2 mechanism for testing 102
Condition.
In actual applications, transfer mechanism 101 may also include mounting bracket 8, transfer cylinder is installed
Plate 9, transfer cylinder 10, cylinder connector mounting blocks 27 and guide rail 11, transfer cylinder mounting plate 9
Being fixed in mounting bracket 8 with guide rail 11, mechanism for testing installing plate 1, on guide rail 11, moves
Carrier gas cylinder 10 is fixed on transfer cylinder mounting plate 9, further through cylinder connector mounting blocks 27 with
Mechanism for testing installing plate 1 is connected, and so, transfer cylinder 10 can be with on mechanism for testing 102
Lower motion；Also can be provided with linear bearing 12 and nut 13 on guide pillar 4, linear bearing 12 is also solid
Being scheduled on cylinder mounting plate 3, spring 5 is between linear bearing 12 and nut 13, so
Having ensured that spring 5 will not be ejected, cylinder 18 top can be provided with cylinder upper limit screw 14 He
Stop screw mounting blocks 15, probe frock bar 6 also can be provided with sealing ring 16, gas quick connector
17, gum-injecting port 20 and gas outlet 21, mechanism for testing 102 may also include probe frock rod sleeve
23, housing supports L plate 22, trachea 25, gas control check valve 26 and leakage test instrument 24,
Probe frock rod sleeve 23 is positioned at below housing supports L plate 22, is supported on two by step
In the coffin that housing supports L plate 22 is formed, housing supports L plate 22 is also secured at cylinder
On installing plate 3, and cylinder 18 head is to be connected with probe frock bar 6 by draw-in groove 19, this
Sample, cylinder 18 just can with probe frock bar 6 under the guiding of probe frock rod sleeve 23,
Do and move along a straight line up and down, owing to sealing ring 16 is peripheral at probe frock bar 6 head, gas outlet 21
One end gas quick connector 17 is installed, the other end is positioned at the elastic probe 7 of probe frock bar 6
On installed surface, the afterbody of elastic probe 7 is positioned at the space of gum-injecting port 20, elastic probe 7
Afterbody connects lead-out wire, and this lead-out wire is connected to electric performance test instrument, and lead-out wire passes through
Gum-injecting port 20 cavity injects sealed colloid and realizes the sealing of elastic probe 7, thus before testing,
The a set of sealing device being made up of sealing ring 16, elastic probe 7 and gas quick connector 17, and
This set of sealing device inserts in probe frock rod sleeve 23, the most slidably can work as gas
Cylinder 18 is retracted, and is pulled up by probe frock bar 6, now, because of probe frock rod sleeve 23
Lower surface (face A) extruding probe frock bar 6 on sealing ring 16 (face B), make sealing ring 16
Axially contract and radially spreading, external diameter increase, thus be close to the inwall of product, it is achieved seal.
By setting the position of upper limit screw 14, the distance that probe frock bar 6 is up can be limited,
Thus define the distance that sealing ring 16 axial compression is shunk, the most just define sealing ring 16 footpath
To swell increment.Reach to ensure that sealing ring 16 realizes reliably sealing by being close to product inwall, and
It is unlikely to again thrust excessive and damage product.
When two products to be measured arrive and specify position, transfer cylinder 10 stretches out, by guide rail 11
Guiding, two set mechanism for testing 102 are pushed into appointment position, now elastic probe 7 touches product
The PIN needle of product, elastic probe 7 can stretch, when elastic probe 7 is a certain amount of, i.e. by compression
The lower surface top of probe frock rod sleeve 23 to behind workpiece upper surface, the piston of transfer cylinder 10
Bar continues to stretch out, cylinder mounting plate 3, linear bearing 12, cylinder upper limit screw 14, spacing
Screw mounting blocks 15, cylinder 18, probe frock rod sleeve 23, sealing ring 16, probe frock
Bar 6, elastic probe 7, gas quick connector 17 etc. all under the guiding of two guide pillars 4, to
Upper motion, spring 5 is compressed, and so, reaches both to ensure that elastic probe 7 is with certain pressure
With product P IN pin good contact, it is ensured that the reliability of electric performance test, the most do not damage product and
The purpose of elastic probe 7.
Testing procedure: first closed by gas control check valve 26, inflates toward revealing test instrument 24
Mouth inflation, has a trachea 25 owing to revealing in the middle of test instrument 24 and gas control check valve 26,
So the test that can form pressure stability in pipeline the most between seals gas,
After product is sealed by circle 16 to be sealed, gas control check valve 26 is opened, by the most stable
Pressed gas enters in product and tests.Owing to gas control check valve 26 is against workpiece, so gas
Control check valve 26 and the pressed gas revealed between test instrument 24 in pipeline are more, the most surely
The gas reserved is more, and the pressed gas entering product is the most less, it is possible to achieve test
Pressed gas rapid equalisation is stable, and the force value undulate quantity of test pressed gas is the least, carries
High testing efficiency and measuring accuracy.
