Automobile dust cover fatigue testing machine

The invention relates to an automobile dust cover fatigue testing machine. A swing shaft driving mechanism is mounted on a top end side of a casing, a vertically arranged rotating shaft is mounted onan output end of the swing shaft driving mechanism in a driven manner, a lower part of the rotating shaft penetrates into the casing, a plurality of transverse cantilever-type swinging shafts are fixedly mounted above and below the rotating shaft in the casing in a spaced manner, a translational plate is mounted on the other side of an inner part of the casing, a translational plate screw nut is fixed on a lower portion of the translational plate, a horizontally arranged translational screw rod is installed in the translational plate screw nut in an engaged manner, the translational screw rodis coaxially connected to an output shaft of a translational mechanism motor which is fixed in a lower portion of the casing, the translational mechanism motor drives the translational screw rod to rotate, then the translation
