Device and method for detecting tooth part size of trapezoid jaw clutch

The present invention discloses an apparatus and method for detecting jaw clutch teeth trapezoidal portion size. Be detected trapezoidal jaw on the horizontal rotary table; a stepping motor connected by a ball screw coupling and precision positioning the platform; and a stepping motor connected to the drive motor; an encoder and a motor driver connected to the PLC; red line array laser light source is mounted on the fixed bracket; camera shooting vertically downwards, the front end of the camera lens with the red filter; camera connected to the computer by the image acquisition card; PLC connected to the computer. The present invention employs a linear array laser as a light source, an image formed by irradiation on the trapezoidal jaw clutch teeth, the use of machine vision methods for image processing, to obtain a trapezoidal jaw clutch teeth portion size, to solve the trapezoidal jaw clutch detection period slow the production process, the problem of low accuracy.
