Ultrasonic roll finishing device adaptable to complex surfaces

Abstract

The invention provides an ultrasonic roll finishing device adaptable to complex surfaces. The ultrasonic roll finishing device adaptable to complex surfaces comprises a shell assembly, a hydraulic assembly and an ultrasonic assembly. The ultrasonic assembly is fixed in the shell assembly and comprises a transducer, an amplitude transformer and a tool head, wherein the transducer is connected with an ultrasonic generator; the first end of the amplitude transformer is connected to the first end of the transducer, and two edge curves of the radial section of the amplitude transformer are Bezier curves; and the tool head is detachably connected to the second end of the amplitude transformer. By adoption of the ultrasonic roll finishing device adaptable to complex surfaces, the probability of movement failures caused by environment changes or self faults can be lowered and even prevented; and the ultrasonic roll finishing device adaptable to complex surfaces has the advantages of being high in efficiency, small in energy loss, small in size, long in service life, good in heat dissipation performance, high in flexibility, good in universality and low in weight.

Description

technical field [0001] The invention relates to the field of metal surface treatment devices, in particular to an ultrasonic rolling processing device adapted to complex surfaces. Background technique [0002] Surface rolling strengthening is a better surface strengthening method, which can prepare fine nano-layers on the surface of parts and improve the performance coefficient of materials in all aspects; it can also be used on the surface of damaged workpieces, such as aircraft engine blades. Such parts put into use are repaired twice to extend the service period and obtain nano-scale surface finish at the same time, which is helpful for reducing the surface roughness of the parts, introducing residual compressive stress, and improving the corrosion resistance, wear resistance and fatigue resistance of the parts are of great significance. [0003] Ultrasonic rolling processing is a working method that combines ultrasonic impact energy and static load rolling, and is a mor...

AI Technical Summary

Problems solved by technology

[0004] Existing ultrasonic rolling processing devices generally have a small measuring range, and their processing range cannot meet the strength requirements required for high-strength material experiments

And the head housing of the existing device used to fix the head tool head is integrally formed or non-detachably fixedly connected to the housing body. After a period of use, the head housing will wear out but cannot be replaced, causing the tool head to loosen. It can no longer play a fixed role; and the existing device after wear will affect the processing accuracy. If the same parameters are set and the same material is treated for a period of time, the results will be different.
