Examination terminates.1.8 ° of the step angle of motor 66,200 steps/week, micrometer 4 rotate a circle axial movement 50 (1=
0.01mm), so axial movement distance 0.25/step, each stroke of tested microswitch 9 can be measured with this；Meanwhile, by pressure
Force transducer 65, conditioning amplification circuit module 84 and a/d modular converter 85 measure the axial compressive force that drive rod 91 is applied.Filter
Bob is used for filtering the effect of unstable and vibration during contact switching by hardware compared with circuit module 83.
In test process, in tester panel 7, one group of the left side of digital display module 86 charactron shows successively by micrometer
Move the pretravel of switch 9, cross stroke, differential movement parameter (unit mm)；One group of the right charactron shows corresponding to stroke successively
Action force, total travel force, release force parameter (unit n), if period have parameter unqualified it indicates that in lamp module 87 with this ginseng
The corresponding red leds of number are bright, if all parameters all qualified it indicates that the green indicating lamp in lamp module 87 is bright and with honeybee
Ring device 89 send " too " sound, point out this tested microswitch 9 qualified.In test process, if touching because of tested microswitch 9
The booties such as dust are had on point or because contact surface concavo-convex generation loose contact is it indicates that " have and the flash " redness in lamp module 87 refers to
Show that lamp is bright.
In sum, the microswitch stroke of the present embodiment and automatic pressure-testing device, can be automatically to microswitch
Pretravel, cross stroke, differential movement, action force, total travel force, the technical parameter such as release force measure, compared to existing
Manual detection mode in technology, can significantly mitigate the labor intensity of test workman, testing efficiency is greatly improved；During use, energy
Enough effectively realize microswitch multiple parameters disposably quick, in high precision, automatic test；Tester only needs to by listening
The sound that buzzer sends, you can know to be test for microswitch whether test passes, thus further mitigating tester
The labor intensity of member, improves testing efficiency；In addition, tester only need to observe the corresponding finger in the indicating lamp module of tester
Show lamp be the corresponding qualified of can be known microswitch whether, easy to operate.
Attached: the explanation of nouns of microswitch related to the present embodiment:
Action force: run to operating position from free position and must be added to the power drive rod.
Restoring force: run to reset position from total travel position and issue the power being added to drive rod.
Total travel force: run to total travel position from free position and must be added to the power drive rod.
Pretravel: from the displacement to operating position for the free position of drive rod or move angle.
Cross stroke: from the displacement to total travel position for the operating position of drive rod or move angle.
Total kilometres: from the displacement to total travel position for the free position of drive rod or move angle.
Movement is poor: from the displacement to reset position for the operating position of drive rod or move angle.
Free position: do not apply drive rod position during external force.
Operating position: drive rod is subject to external force, travelling contact just starts drive rod when inverting from free position state
Position.
Reset position: reduce the external force on drive rod, travelling contact just starts to be returned from by position from action location status
Drive rod position during configuration state.
Total travel position: the position of drive rod when drive rod reaches transmission stop position.
Above example is the explanation of the specific embodiment to the present invention, rather than limitation of the present invention, relevant technology
The technical staff in field without departing from the spirit and scope of the present invention, can also make various conversion and change and obtain
To corresponding equivalent technical scheme, therefore all equivalent technical schemes all should be included into the patent protection model of the present invention
Enclose.
