The invention discloses an automatic coupling system and method for a steel rail welding seam ultrasonic flaw detection sensor, the system comprises an automatic flaw detection platform and a transmission device, and the transmission device is used for realizing the transmission of the automatic flaw detection platform in the horizontal direction; a stereoscopic vision camera, a spraying device, a pressure sensor, an ultrasonic flaw detection sensor and a control module are integrated on the automatic flaw detection platform. The position relation between the ultrasonic flaw detector and the steel rail is acquired through the stereoscopic vision camera, and after a coupling agent is sprayed, the stepping motor is adjusted by utilizing a pressure sensing value obtained by the pressure sensor to complete height adjustment of the ultrasonic flaw detector. The ultrasonic flaw detector is well coupled with the steel rail under the full-automatic condition, flaw detection sensitivity calibration is completed, the ultrasonic signal transmission efficiency is improved, interference in the detection signal transmission process is reduced, the service life of an ultrasonic detection sensor is effectively prolonged, and the large-scale and rapid detection requirement is met.
