The invention discloses a device and method for enhancing steel-based surface composite structure or steel-based surface repair. The device comprises micro impact heads, an ultrasonic impact tool head, an ultrasonic amplitude-change pole and an air pressure auxiliary type ultrasonic impact module. The lower ends of the micro impact heads are convex curved surfaces, the multiple micro impact headsare densely arranged, and enveloping surfaces formed by the lower ends of the micro impact heads are matched with the shape of the bottoms of grooves to be reinforced; the upper ends of the micro impact heads are fixed to the ultrasonic impact tool head; the ultrasonic impact tool head is fixed to the ultrasonic amplitude-change pole; and the ultrasonic amplitude-change pole is installed on the air pressure auxiliary type ultrasonic impact module, and the air pressure auxiliary type ultrasonic impact module is used for adjusting the posture of the ultrasonic amplitude-change pole. Compared with the prior art, the shape of the micro impact heads of the invention can be adjusted at any time according to the actual situation, so that it is guaranteed that ultrasonic impact strengthening can be fully conducted on the surface to be machined every time, and fine and regular ultrasonic impact strengthening holes are formed.
Description
technical field [0001] The invention relates to the technical field of material surface strengthening, in particular to a device and method for strengthening a steel-based surface composite structure or steel-based surface repair. Background technique [0002] With the development of society and science and technology, the performance requirements for materials and structures are also gradually increasing. It is difficult for single-performance material structures and traditional industrial manufacturing to meet the production requirements of today's modern industries. At present, under various impact loads in construction machinery, mining machinery and building materials machinery, the surface reinforcement layer of the liner structure has poor wear resistance and is easy to fall off. The service period of traditional single wear-resistant metal materials (Mn13) in mining machinery is getting shorter and shorter, and the preparation of high-performance composite materials ...
