Automatic mounting and positioning method for side window of railway vehicle

The invention discloses an automatic mounting and positioning method for a side window of a railway vehicle, which comprises the following steps of: dividing a region through a laser range finder, and parking a vehicle body to a specified region; a laser range finder is used for measuring the accurate distance of the end of the vehicle body in real time, and a computer is used for auxiliary calculation to determine the accurate position of the vehicle body. The robot carries a travel switch and laser scanning equipment, and the travel switch detects the periphery of a vehicle window frame and determines the accurate size and inclination angle of the window frame. Laser scanning equipment scans the outer surface of the window frame to determine the edge size of the window frame. And computer-assisted calculation is used to realize automatic installation and accurate positioning of the side window. According to the invention, the influence of slight vehicle body position movement, vehicle body manufacturing err
