Embodiment
As depicted in figs. 1 and 2, the utility model comprises desktop electric rotating mechanism (motor) 1, ABS gear ring 2, locating wheel 3, digital optic fiber sensor 4, sensor stand 5, stepper motor 6, stepper motor bracing frame 7, screw rod 8, base 9 based on the ABS gear ring quality detection device of digital optic fiber sensor, wherein desktop electric rotating mechanism (motor) 1 is installed on base 9, for exporting rotary driving force.Locating wheel 3 is connected with it by the output shaft of desktop electric rotating mechanism (motor) 1 and is rotated.ABS gear ring 2 to be measured is installed on locating wheel 3 and rotates with the output shaft synchronous of desktop electric rotating mechanism (motor) 1.Digital optic fiber sensor 4 is installed on sensor stand 5, regulate the distance of the horizontal direction of digital optic fiber sensor 4 and ABS gear ring 2 by turning screw rod 8 after setting threshold value, digital optic fiber sensor 4 is made to export the threshold range set, host computer sets desktop electric rotating mechanism (motor) angular velocity of rotation, stepper motor step distance, stepping rate and the ABS gear ring number of teeth to be measured, desktop electric rotating mechanism (motor) 1 drives ABS gear ring 2 to rotate, and realizes circular pitch error-detecting by digital optic fiber sensor 4.Desktop electric rotating mechanism often revolves and turns around, the stepper motor 6 being fixed on stepper motor bracing frame 7 drives digital optic fiber sensor 4 vertically above to move a unit stepping length rapidly, start a new circle Scanning Detction again, until complete the scanning to the whole ABS gear ring flank of tooth, realize detecting the complete scan of ABS gear ring 2 flank of tooth defect (as hypodontia, broken teeth, flank of tooth out-of-flatness etc.).
Digital optic fiber sensor 4 launches the ruddiness of 632nm through light-emittingdiode, is radiated on the single tooth of ABS gear ring 2.Digital optic fiber sensor 4 sets light intensity radix, exports high level when the light intensity reflected is greater than radix, on the contrary output low level.The output of digital optic fiber sensor 4 is the timer module of full sized pules signal to MSP430 single-chip microcomputer, the time that the time utilizing MSP430 single-chip microcomputer to be occurred by the rising edge that the catching of timer module/comparand register catches pulse signal and negative edge are occurred, obtain high level pulsewidth 10, low-level pulse width 11 by calculating.Save as two arrays respectively, high level pulsewidth is a
i, low-level pulse width is b
j, and try to achieve high level pulsewidth mean value A, low-level pulse width mean value B, each high level pulse width error is (a
i-A)/A*100%, each low-level pulse width error is (b
j-B)/B*100%, finally tries to achieve maximum deviation, judges that whether it is qualified.
