Roof laser brazing double-side flexible trailing compression system

Abstract

The invention discloses a roof laser brazing double-side flexible trailing compression system. The roof laser brazing double-side flexible trailing compression system comprises a laser brazing joint,a Y-direction moving module and a control communication module, wherein two mounting base plates are fixedly connected to both sides of the laser brazing joint respectively, first air cylinders and adaptive pressure wheel sets are respectively installed on the lower end of each mounting base plate, and the mounting base plates are connected with a robot; the Y-direction moving module is connectedwith the adaptive pressure wheel sets so as to adjust the horizontal position of pressure wheels in real time according to the position of welding, so that the pressure wheels are matched with the laser brazing joint, and double-side welding of a single station is completed; and the control communication module is electrically connected with the robot, the intake direction of the first air cylinders is changed by an electromagnetic directional valve so as to control the movement of the first air cylinders, an electric proportional valve is connected so as to adjust the air pressure, and the proportional valve is controlled by a closed loop so as to adaptively adjust the output pressure of the first air cylinders. According to the roof laser brazing double-side flexible trailing compressionsystem, the optimally designed double-side trailing pressure wheels are adopted, so that the problems of bulges in the side position of the roof and large fluctuation of the roof are solved, and welding beams on both sides of the roof can be welded once, so that the working efficiency is improved, and the input is reduced.
