Problems solved by technology

The projectile hits the workpiece at a certain speed under the impact of the vibrating head, and generates residual compressive stress on the surface of the workpiece, so that the surface of the workpiece can be uniformly treated, the fatigue resistance of the workpiece can be improved, and the purpose of strengthening is achieved. At present, there is no related equipment It is urgent to develop a new type of swinging ultrasonic shot peening equipment for surface strengthening treatment of fans with damping tables

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of fan blade surface treatment devices, in particular to a swing type ultrasonic shot peening strengthening equipment. Background technique [0002] In an aero-engine, the blade is the main part that generates power. In a turbofan engine, generally, a raised part that is connected to each other is provided at a position where the height of the fan blade is appropriate, which is called a damping table, and its function is to form a ring between the blades. Belt, the damping table increases the rigidity of the blade and prevents the fan blade from chattering. The damping table is an important part of the fan blade, and the surface quality of the damping table directly affects the fatigue life of the fan blade, as well as the safety and reliability of the entire engine. In order to improve the fatigue strength of the damping table, the surface strengthening process is generally used for strengthening treatment...
