Steel rail welding seam polishing system

The invention discloses a steel rail welding seam polishing system which comprises a polishing room and a control system. A polishing system and a visual positioning system are arranged in the polishing room, and the steel rail welding seam polishing system is characterized in that the polishing system comprises a mechanical arm and an end effector, the end effector comprises abrasive belt mechanisms and a support, and the support comprises a cross arm and two connecting arms located at the two sides of the cross arm; and each connecting arm is provided with one abrasive belt mechanism, and the two abrasive belt mechanisms are opposite to each other. According to the steel rail welding seam polishing system, qualitative defect detection of steel rail surface quality and quantitative detection of working allowance can be fully automatically realized, manual measurement by manual eye observation, micrometer and the like on a current long rail production line is replaced, the detection efficiency is high, and th
