The microswitch stroke of the present embodiment and automatic pressure-testing device, its course of work and principle of work are summarized as follows:
Before using, for the model of tested microswitch 9, by the button of the key-press module 88 on tester panel 7, each parameter permissible values such as the stroke of tested microswitch 9 and pressure are carried out presetting accordingly; Then, tested microswitch 9 is placed between the first holder 23 of clamp assemblies 2 and the second holder 24, and makes the driving stem 91 of tested microswitch 9 towards the left side of the push head 36 of action component 3; Then by manual clutch 21 and connecting link 22 action of clamp assemblies 2, the first holder 23 is driven to move right, thus match with the second holder 24 tested microswitch 9 clamped, now, the first probe 61, second probe 62 of worktable circuit unit 6, the 3rd probe 63 and four point probe 64 contact with the respective terminal of tested microswitch 9 respectively; Test job equipment is ready, and now press the testing button 67 of lower table circuit unit 6, stepper motor 66 drives milscale 4 to turn clockwise by shaft coupling 5; Milscale 4 promotes push strut 35, pressure transducer 65 and push head 36 and relies on the second slide block 32 on slide rail 31 to left movement, be pretravel (PT) when push head 36 and the driving stem 91 of tested microswitch 9 just contact the displacement started between tested microswitch 9 operating position, the power be now added on driving stem 91 is action force; Be stroke (OT) from driving stem 91 operating position to the displacement of total travel position, the power be now added on driving stem is total kilometres power (TF); Then stepper motor 66 drives milscale 4 to be rotated counterclockwise by shaft coupling 5 under program, milscale 4 drives push strut 35, pressure transducer 65 and push head 36 to rely on the second slide block 32 to move right on slide rail 31, displacement from the operating position of driving stem 91 to reset position is differential movement (MD), and the power be now added on driving stem 91 is release force (RF); When the driving stem 91 of microswitch 9 returns back to free position, step motor stop, once tests end.The step angle of stepper motor 66 1.8 °, in 200 step/weeks, milscale 4 rotates a circle and moves axially 50 (1=0.01mm), so move axially distance 0.25/step, can measure each stroke of tested microswitch 9 with this; Meanwhile, measure by pressure transducer 65, conditioning amplification circuit module 84 and A/D modular converter 85 axle pressure that driving stem 91 is applied.Instability when filtering comparator circuit module 83 is for switching by hardware filtering contact and the effect of vibration.
In test process, on tester panel 7, one group, the left side charactron of digital display module 86 shows pretravel, excessively stroke, the differential movement parameter (unit mm) of tested microswitch 9 successively; The one group of charactron in the right shows the action force corresponding to stroke, total kilometres power, release force parameter (unit N) successively, if period has parameter defective, then corresponding with this parameter in indicating lamp module 87 red led is bright, if all parameters are all qualified, green indicating lamp then in indicating lamp module 87 bright and with hummer 89 send " too " sound, point out this tested microswitch 9 qualified.In test process, if the contact because of tested microswitch 9 has the booties such as dust or because of the concavo-convex generation loose contact of surface of contact, then " have and the flash " red led in indicating lamp module 87 is bright.
In sum, the microswitch stroke of the present embodiment and automatic pressure-testing device, can automatically measure technical parameters such as the pretravels of microswitch, excessively stroke, differential movement, action force, total kilometres power, release force, compare to manual detection mode of the prior art, significantly can alleviate the labour intensity of test workman, significantly improve testing efficiency; During use, effectively can realize disposable quick, high precision, the automatic test of the multiple parameter of microswitch; Tester only needs the sound by listening hummer to send, and can know tested microswitch whether test passes, thus further mitigate the labour intensity of tester, improve testing efficiency; In addition, tester only needs the corresponding pilot lamp in the indicating lamp module of observation test instrument whether can know qualified corresponding to microswitch, 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 power driving stem.
Restoring force: run to reset position from total travel position and issue the power be added to driving stem.
Total kilometres power: run to total travel position from free position and must be added to power driving stem.
Pretravel: the displacement from the free position of driving stem to operating position or move angle.
Cross stroke: the displacement from the operating position of driving stem to total travel position or move angle.
Total kilometres: the displacement from the free position of driving stem to total travel position or move angle.
