In the top of longitudinal worm screw 19, the longitudinal direction worm screw 19 engages connection with lateral worm screw 17;
Motor 18, the motor 18 are fixed on 4 top of rack, are fixed with connecting rod 13, institute on the output shaft of the motor 18
The both ends for stating connecting rod 13 are equipped with deflector roll 20, and the side of the rack 4 is fixed with fixed plate 11, the both ends point of the fixed plate 11
It is not connected with the first test mandril 12 and the second test mandril 14, the first test mandril 12 and the second test mandril 14
Top be respectively and fixedly provided with wedge block 9.
One end of the transverse direction worm screw 17 is pierced by rack 4 and is fixed with hand-operated wheel 5, by rotating hand-operated wheel 5, can pass through
Lateral worm screw 17 drives longitudinal worm screw 19 to rise or fall, and is adjusted to the height of testboard 6, facilitates test.
Guide post 22 is fixed at the bottom four corners of the testboard 6, the guide post 22 is flexibly connected with rack 4, by leading
Column 22 prevents testboard 6 from rotation occurs, and under the limitation of guide post 22, testboard 6 is only moved up and down, and adjusts low voltage switch
Spacing between test mandril, improves the accuracy of test.
The two sides of the testboard 6 are equipped with wing nut 7, and one end of the wing nut 7 is rotatably connected to push plate 8,
By rotating wing nut 7, it can drive push plate 8 that low voltage switch is clamped fixation, prevent low during the test
Pressure electric switch moves.
It is equipped in rack 4 right above the connecting rod 13 close to switch 10, it is described to pass through conducting wire electrical property close to switch 10
It is connected with counter, can be close proximity to switch 10 when connecting rod 13 turns to highest point, and then trigger close to switch 10 to open
Dynamic counter counts the number of revolutions of connecting rod 13, which represents the testing time of low voltage switch.
Indicator light 21 is also equipped on the testboard 6, indicator light 21 is used to limit the test response of low voltage switch
As a result, indicator light 21 is attached by conducting wire and low voltage switch, in a test process, indicator light flashing is primary,
The electric-controlled box 3 electrically controls camera 1, motor 18, indicator light 21 and counter by conducting wire, is equipped on electric-controlled box 3 total
Power switch, can simultaneously start and stop camera 1, motor 18, indicator light 21 and counter.
The first test mandril 12 and the second test mandril 14 are identical as the distance between 18 shaft of motor, when motor 18
When rotation, periodically successively the first test mandril 12 and the second test mandril 14 can be pushed with drive link 13, when even
Deflector roll 20 on bar 13 to wedge block 9 close to when, deflector roll 20 squeezes the inclined-plane on wedge block 9, so that the first test mandril
12 rise, so that the second test mandril 14 declines, carry out pressing test to low voltage switch.
Limited block 15 is respectively and fixedly provided on the first test mandril 12 and the second test mandril 14, under the fixed plate 11
Spring 16 is socketed between surface and the first test mandril 12, between the upper surface of the fixed plate 11 and the second test mandril 14
It is socketed with spring 16, by limited block 15, the stroke of test mandril can be limited, prevent test 14 Bottom Runby of mandril
It is excessive and damage low voltage switch.
Specifically, in use, need to low voltage switch to be tested be placed on testboard 6, screw 6 two sides of testboard
Wing nut 7 so that low voltage switch is clamped fixation by push plate 8, then by shaking hand-operated wheel 5, drive lateral snail
Bar 17 drives longitudinal worm screw 19 to rise, and is adjusted to the height of testboard 6, so that the first test mandril 12 presses low-voltage electrical apparatus
The side of switch, the second test mandril 14 after adjusting, pass through electric-controlled box vacantly in the top of the low voltage switch other side
3 starting cameras 1, motor 18, indicator light 21 and counter, drive connecting rod 13 to rotate, so that on connecting rod 13 by motor 18
Deflector roll 20 boosts the first test mandril 12, while the second test mandril 14 being pushed, and then complete one to low voltage switch
Secondary test can record entire test process as the rotation period of connecting rod 13 is recycled using camera 1, will indicate
Meter reading when lamp 21 no longer lights is calculated as test result.
