The invention relates to an electromagnetic vibration roll riveting fixing device for a knuckle bearing.One end of each of three spring plates (5) is fixed in a corresponding groove in a round boss of a spring connecting plate (1), and the other end of each spring plate (5) is fixed in a corresponding groove in the upper end of a main spindle (19).A field coil (21) is arranged in an L-shaped cavity in a field core (20) in a winding mode, a power coil (22) is arranged in an annular groove in the bottom of the side face of the cylindrical body of the main spindle (19) in a winding mode, and a riveting head (17) for roll riveting is installed in a center screw hole in the lower end face of a riveting head connecting cylinder (15).The device has the advantages of being capable of automatically rotating, high in bearing capacity and anti-jamming capacity and the like.During knuckle bearing roll riveting fixation, riveting force required by flanging of an outer ring circular groove of the knuckle bearing is reduced
