Welding device for aluminum alloy door and window processing

Abstract

The application belongs to the technical field of laser welding, and specifically discloses a welding device for aluminum alloy door and window processing, which comprises an operating table and supporting legs below the operating table, the upper wall of the operating table is provided with a fixed plate, the fixed plate is provided with a movable supporting assembly which is cross-rotated, the two ends of the fixed plate and the movable supporting assembly are respectively provided with telescopic plate assemblies which are rotatably arranged, adjacent telescopic plate assemblies are provided with right-angle locking rods which are slidingly arranged, the two adjacent telescopic plate assemblies are always kept perpendicular, the outer end of the telescopic plate assembly is fixedly provided with an angle automatic splicing assembly along the length direction, the angle automatic splicing assembly is provided with a laser welding assembly, the upper wall of the fixed plate is provided with an angle indicating assembly, and the movable supporting assembly is rotatably driven by a power-off holding self-locking motor. The welding device is driven to adjust the angle by the power-off holding self-locking motor, can automatically position and clamp the four corners of the 45° cut aluminum profile frame, and can complete seamless laser welding, and the problems of traditional clamps, such as complicated clamping, large size cumulative error and poor diagonal line precision, are solved.
