Adjusting block 3 moves on rectangular channel 88, observes position of the pointer 10 on graduated scale 9 at this time, when the signified graduated scale 9 of pointer 10
On scale with detection the pin spacing of sample 14 it is equal when, stop operating adjusting rod 81.After the completion, to will test sample 14 logical
Jack 4 is crossed to be inserted into inner cavity 12, detect sample 14 pin during insertion, when detection sample 14 pin touch branch
After supportting platform 74, drive sliding bar 71 that the elastic force of the 4th spring 74 is overcome to move down in sliding cavity 78 by threaded rod 72, together
When wing plate 77 moved in wing plate slot 79, guarantee sliding bar 71 not can rotate, during sliding bar 71 moves down, due to lock
Tight bar 66 is located inside locking slot 75, and therefore, sliding bar 77 drives bogie 61 to overcome the elastic force of second spring 63 in side slot
It is mobile to the lower part of inner cavity 12 in 65, when bogie 61 is mobile to the bottom of inner cavity 12, acted in the direction of roller gear 53
Under, it drives movable stand 51 mobile to the top of inner cavity 12 on sliding groove 54, during movable stand 51 moves up, passes through connecting rod
55 promotion conductive columns 55 slide in annular guide post 511, when pin is fixed in the conductive column 55 when both sides, connecting rod 55
It will be unable to continue to press on conductive column 59, to compress the first spring 56, at this moment the pressure value of pressure sensor 58 can be with
The compression of the first spring 56 and increase, after pin completion is inserted into inner cavity 12, pressure that pressure sensor 58 is experienced
Value remains inconvenient, when measuring capacitor, to guarantee that conductive column 59 and pin are in close contact, guarantees the stability being powered, needs simultaneously
Taking into account conductive column 59 cannot be excessive to the pressure of pin, the excessive damage that will cause pin of pressure, therefore pressure sensor 58
Equipped with a threshold value, after detection sample 14 is completely inserted into inner cavity 12, if the threshold value that pressure sensor 58 is experienced does not surpass
Over-voltage force threshold illustrates the pin insufficient pressure of 59 pairs of conductive column detection samples 14, turns threaded rod 72 at this time, drives it and slides
Lever 71 moves down, and at this moment the pin of 59 pairs of conductive column detection samples 14 will be driven to apply pressure by linkage mechanism 6, when
When pressure applied reaches the threshold value of pressure sensor 58, stop adjusting threaded rod 72, if what pressure sensor 58 was experienced
Threshold value is more than pressure threshold, inverts threaded rod 72, until the pressure that pressure sensor 58 is experienced reaches threshold value.It adjusts and completes
Afterwards, capacitor pin to be measured is inserted into inner cavity 12 and is measured by jack 4, after measurement, by lower button 14,
At this moment electromagnet 68 obtains electric generation magnetic force, generates suction to check lock lever 66, it is made to overcome the elastic force of third spring 67 to close to electricity
The direction of magnet 68 is mobile, when check lock lever 66 completely disengages locking slot 75, under the pulling force of second spring 63, it will drives and drives
Moving frame 61 is mobile to the top of inner cavity 12, so that conductive column 59 be made to unclamp the pin of capacitor, at this moment takes out after release button 13
Survey measured capacitor, in release button 13,68 power loss of electromagnet, check lock lever 66 under the thrust of third spring 67 with sliding
The surface of bar 71 contacts, and after taking out capacitor, under the elastic force of the 4th spring 76, sliding bar 71 is moved up, and is being moved through
Cheng Zhong, when locking slot 75 and 66 face of check lock lever, check lock lever 66 is moved to locking slot 75 under the action of third spring 67
In, after the completion, measuring next capacitor.
Based on above-mentioned, clamping device is detected using a kind of capacitance of capacitor of the invention, before measure capacitance, elder generation
Distance of center circle between two jacks is adjusted by regulating mechanism, keeps distance of center circle equal with the pin spacing of capacitor, then according to pin
Length suitably adjusts driving mechanism, makes pin when being inserted into jack, can make driving mechanism normal driving linkage mechanism, measure
When capacitance, after capacitor is inserted into jack, linkage mechanism movement is driven by driving mechanism, and then drive fixed mechanism and pin
