All parameters of switch 9 are qualified, conveniently test and improve testing efficiency.
The easy-operating microswitch stroke of the present embodiment and automatic pressure-testing device, its course of work and operation principle
It is summarized as follows：
Using front, for the model of tested microswitch 9, will be tested by the button of the key-press module 88 in tester panel 7
Each parameter permissible value such as the stroke and pressure of microswitch 9 carries out corresponding presetting；Then, tested microswitch 9 are placed in
Between first holder 23 and the second holder 24 of clamp assemblies 2, and the drive rod 91 of tested microswitch 9 is made towards action
The left side of the push head 36 of component 3；Then pass through 22 action of manual clutch 21 and connecting rod of clamp assemblies 2, drive the
One holder 23 is moved right, and is clamped tested microswitch 9 so as to be engaged with the second holder 24, now, workbench electricity
First probe 61 of road component 6, the second probe 62, the 3rd probe 63, and the 4th probe 64 phase respectively with tested microswitch 9
Terminal is answered to contact；Test job equipment is ready, now presses the testing button 67 of workbench circuit unit 6, motor 66
Micrometer 4 is driven to turn clockwise by shaft coupling 5；Micrometer 4 promote push strut 35, pressure transducer 65 and push head 36 according to
Ask the second slide block 32 on slide rail 31 to left movement, when push head 36 is just contacted out with the drive rod 91 of tested microswitch 9
Begin to the displacement between 9 operating position of tested microswitch to be pretravel（PT）, the power being now added on drive rod 91
For action force；It was stroke from 91 operating position of drive rod to the displacement of total travel position（OT）, now it is added in drive rod
On power be total travel force（TF）；Then motor 66 drives micrometer 4 to revolve counterclockwise by shaft coupling 5 under program
Turn, micrometer 4 drives push strut 35, pressure transducer 65 and push head 36 to rely on the second slide block 32 to be transported on slide rail 31 to the right
It is dynamic, it is differential movement from displacement of the operating position of drive rod 91 to reset position（MD）, now it is added on drive rod 91
Power be release force（RF）；When the drive rod 91 of microswitch 9 returns back to free position, step motor stop is once tested
Terminate.1.8 ° of the step angle of motor 66,200 steps/week, micrometer 4 rotate a circle and move axially 50（1=0.01mm）,
So axial movement distance 0.25/step, with this it is measurable go out 9 each stroke of tested microswitch；Meanwhile, by pressure transducer
65th, conditioning amplification circuit module 84 and A/D modular converters 85 measure the axial compressive force applied to drive rod 91.Filtering is more electric
Road module 83 for by hardware filter contact switch when it is unstable and vibration effect.
In test process, in tester panel 7, one group of the left side of digital display module 86 charactron is shown successively by micrometer
It is dynamic to switch 9 pretravel, cross stroke, differential movement parameter（Unit mm）；The one group of charactron in the right shows corresponding to stroke successively
Action force, total travel force, release force parameter（Unit N）If period has parameter unqualified, it indicates that with the ginseng in lamp module 87
The corresponding red leds of number are bright, if all parameters are qualified, it indicates that 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
There are the booties such as dust on point or loose contact is produced because contact surface is concavo-convex, it indicates that " have and the flash " redness in lamp module 87 refers to
Show that lamp is bright.
In sum, the easy-operating microswitch stroke and automatic pressure-testing device of the present embodiment, can be automatically right
The pretravel of microswitch, the technical parameter such as stroke, differential movement, action force, total travel force, release force excessively are measured, compared with
In manual detection mode of the prior art, can significantly mitigate the labor intensity of test workman, greatly improve testing efficiency；Make
Used time, can effectively realize disposable quick, high accuracy, the automatic test of microswitch multiple parameters；Tester only needs
Will be by the sound of listening buzzer to send, you can know to be test for microswitch whether test passes, so as to further mitigate
The labor intensity of tester, improves testing efficiency；In addition, tester need to be only observed in the indicating lamp module of tester
Corresponding display lamp be the corresponding qualified of can be known microswitch whether, it is easy to operate.
It is attached：The explanation of nouns of microswitch related to the present embodiment：
Action force：Operating position is run to from free position and must be added to the power on drive rod.
Restoring force：Reset position issue is run to from total travel position and is added to the power on drive rod.
Total travel force：Total travel position is run to from free position and must be added to the power on drive rod.
Pretravel：Displacement or move angle from the free position of drive rod to operating position.
Cross stroke：Displacement or move angle from the operating position of drive rod to total travel position.
Total kilometres：Displacement or move angle from the free position of drive rod to total travel position.
Movement is poor：Displacement or move angle from the operating position of drive rod to reset position.
Free position：Drive rod position during external force is not applied.
Operating position：Drive rod is subject to external force, travelling contact just to start drive rod when inverting from free position state
Position.
Reset position：The external force on drive rod is reduced, 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 the technical scheme of corresponding equivalent, therefore the technical scheme of all equivalents should be included into the patent protection model of the present invention
Enclose.
