When there are such as jerk abnormal conditions during examination, by pressing " rotating forward " and " reversion " button to control stepper motor 66 manually
First 36 are will push against to adjust to required position." rotating forward " button is pinned, motor is continuously rotated forward, push strut is moved to left to required position, pine
Drive " rotating forward " button to stop, " reversion " is as the same.
Buzzer 89 is fixedly installed on the upper right corner of tester panel 7.Buzzer 89 when in use, works as tested microswitch
When 9 all parameters are qualified, the sounding of buzzer 89 when tester tests, hears that the sound of buzzer 89 then shows tested fine motion
All parameters of switch 9 are qualified, conveniently test and improve testing efficiency.
The microswitch stroke and automatic pressure-testing device of the present embodiment, its course of work and operation principle summary are such as
Under：
Using preceding, 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 make the drive rod 91 of tested microswitch 9 towards action
The left side of the push head 36 of component 3；Then acted by the manual clutch 21 of clamp assemblies 2 and connecting rod 22, drive the
One holder 23 is moved right, and clamps 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 respectively with the phase of tested microswitch 9
Terminal is answered to be in contact；Test job equipment is ready, now presses the testing button 67 of workbench circuit unit 6, stepper motor 66
Micrometer 4 is driven to turn clockwise by shaft coupling 5；Micrometer 4 promote push strut 35, pressure sensor 65 and push head 36 according to
The second sliding block of support 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 as pretravel between the operating position of tested microswitch 9（PT）, now it is added in the power on drive rod 91
It is operation force；It is overtravel from the operating position of drive rod 91 to the displacement of total travel position（OT）, now it is added in drive rod
On power be total travel force（TF）；Then stepper motor 66 drives micrometer 4 to revolve counterclockwise by shaft coupling 5 under program
Turn, micrometer 4 drives push strut 35, pressure sensor 65 and push head 36 to rely on the second sliding block 32 to be transported to the right on slide rail 31
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 stepper motor 66,200 steps/week, micrometer 4 rotates a circle and moves axially 50（1=0.01mm）,
So axial movement distance 0.25/step, with this it is measurable go out each stroke of tested microswitch 9；Meanwhile, by pressure sensor
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 is used to filter unstable and vibration effect when contact switches by hardware.
In test process, one group of the left side of digital display module 86 charactron shows by micrometer successively in tester panel 7
Pretravel, overtravel, the differential movement parameter of dynamic switch 9（Unit mm）；One group of the right charactron shows corresponding to stroke successively
Operation 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 led of number is bright, if all parameters are 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
There are the booties such as dust on point or produce loose contact because contact surface is concavo-convex, it indicates that " have and the flash " red in lamp module 87 refers to
Show that lamp is bright.
In sum, the microswitch stroke and automatic pressure-testing device of the present embodiment, can be automatically to microswitch
The technical parameter such as pretravel, overtravel, differential movement, operation force, total travel force, release force measure, compared to existing
Manual detection mode in technology, can significantly mitigate the labour intensity of test workman, greatly improve testing efficiency；When using, energy
Enough disposable quick, high accuracy, automatic tests for effectively realizing microswitch multiple parameters；Tester is only needed to by listening
The sound that buzzer sends, you can know to be test for microswitch whether test passes, so as to further mitigate tester
The labour intensity of member, improves testing efficiency；In addition, tester need to only observe the corresponding finger in the indicating lamp module of tester
Whether show the lamp i.e. corresponding qualified of can be known microswitch, it is easy to operate.
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：The power that reset position issue is added on drive rod is run to from total travel position.
Total travel force：The power that total travel position must be added on drive rod is run to from free position.
Pretravel：Displacement or move angle from the free position of drive rod to operating position.
Overtravel：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 without applying external force.
Operating position：Since drive rod be subject to external force, travelling contact drive rod just inverted free position state when
Position.
Reset position：The external force on drive rod is reduced, since travelling contact is returned from by position acting location status just
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 to specific embodiment of the 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 should be included into patent protection model of the invention
Enclose.
