Detection device for aluminum profile processing

The utility model discloses a detection device for aluminum profile processing, and relates to the technical field of aluminum profile detection devices. The device comprises a detection frame, positioning frames are symmetrically arranged in the detection frame, a drawing board is fixedly mounted at the upper end of one positioning frame, mounting plates are fixedly mounted at the front end and the rear end of the detection frame, and guide rods are symmetrically arranged between the two mounting plates. The electric push rod and the ball at the lower end of the moving block move, meanwhile, the paintbrush is driven to move, the ball moves along the surface of the aluminum profile, if an uneven surface is met, the ball moves up and down under the work of the spring, and at the moment, the paintbrush also moves up and down to slide out uneven lines on the drawing board; the flatness of the aluminum profile can be quickly checked, the uneven position of the surface of the aluminum profile can be quickly found
