Movement, the moving distance from the operating position of drive rod 91 to reset position is differential movement (MD), is added in drive rod 91 at this time
On power be release force (RF)；When the drive rod 91 of microswitch 9 returns back to free position, step motor stop is primary to survey
Examination terminates.1.8 ° of the step angle of stepper motor 66,200 steps/week, micrometer 4 rotate a circle axial movement 50 (1=
0.01mm), so axial movement distance 0.25/step, can measure each stroke of tested microswitch 9 with this；Meanwhile passing through pressure
Force snesor 65, conditioning amplification circuit module 84 and A/D conversion module 85 measure the axial compressive force applied to drive rod 91.Filter
Bobbi is used to filter out unstable and vibration effect when contact switching by hardware compared with circuit module 83.
In test process, one group of the left side of digital display module 86 charactron is successively shown by micrometer in tester panel 7
Pretravel, overtravel, the differential movement parameter (unit mm) of dynamic switch 9；One group of the right charactron successively shows corresponding to stroke
Operation force, total travel force, release force parameter (unit N), if during which there is parameter unqualified, in indicating lamp module 87 with the ginseng
The corresponding red indicating light of number is bright, if all parameters are qualified, the green indicator light in indicating lamp module 87 is bright and with bee
The ring sending of device 89 " too " sound, prompt this tested microswitch 9 qualified.In test process, if because of the touching of tested microswitch 9
There are the booties such as dust on point or because contact surface bumps generate poor contact, then " have and flash " red in indicating lamp module 87 refers to
Show that lamp is bright.
In conclusion the easy-operating microswitch stroke and automatic pressure-testing device of the present embodiment, it can be automatic right
The technical parameters such as pretravel, overtravel, differential movement, operation force, total travel force, the release force of microswitch measure, compared with
In manual detection mode in the prior art, can substantially mitigate the labor intensity of test worker, greatly improve testing efficiency；Make
Used time can effectively realize disposable quick, the high-precision, automatic test of microswitch multiple parameters；Tester only needs
Will by listen buzzer issue sound, i.e., knowable tested microswitch whether test passes, to further mitigate
The labor intensity of tester improves testing efficiency；In addition, tester need to only observe in the indicating lamp module of tester
It is easy to operate whether corresponding indicator light, that is, knowable microswitch corresponding qualified.
It is attached: the explanation of nouns of microswitch related to the present embodiment:
Operation force: the power that operating position must be added on drive rod is run to from free position.
Restoring force: reset position is run to from total travel position and issues the power being added on drive rod.
Total travel force: the power that total travel position must be added on drive rod is run to from free position.
Pretravel: moving distance or move angle from the free position of drive rod to operating position.
Overtravel: moving distance or move angle from the operating position of drive rod to total travel position.
Total kilometres: moving distance or move angle from the free position of drive rod to total travel position.
Movement is poor: moving distance or move angle from the operating position of drive rod to reset position.
Free position: drive rod position when external force is not applied.
Operating position: drive rod of the drive rod by external force, when travelling contact is just inverted since free position state
Position.
Reset position: reducing the external force on drive rod, and travelling contact is returned from since movement location status is just by position
Set drive rod position when state.
Total travel position: the position of drive rod when drive rod reaches transmission stop position.
Above embodiments are the explanations to a specific embodiment of the invention, rather than limitation of the present invention, related technology
The technical staff in field without departing from the spirit and scope of the present invention, can also make various transformation and variation and obtain
To corresponding equivalent technical solution, therefore all equivalent technical solutions should be included into patent protection model of the invention
It encloses.
