The invention discloses swing type ultrasonic shot peening strengthening equipment. The shot peening strengthening equipment comprises an ultrasonic vibrating device, a shot peening chamber and a blade clamping device, wherein the shot peening chamber comprises an outer chamber and an inner chamber for accommodating shots; the inner chamber is rotatably connected with the outer chamber; the ultrasonic vibrating device is fixedly connected with the outer chamber; and the inner chamber is fixedly connected with the blade clamping device. The shot peening device comprises the outer chamber and the inner chamber positioned in the outer chamber, the inner chamber can swing in the outer chamber to form a swing type shot peening chamber, the shortcoming of low shot peening efficiency is overcome,the problem that the angle of incoming of the shots is not adjustable is solved, the ultrasonic shot peening strengthening efficiency of a damping table can be improved effectively, multi-angle shotpeening strengthening on the damping table of blades of a fan is realized, and the real-time ultrasonic shot peening strengthening effect is enhanced.
