Ultrasonic-assisted fluid cavitation grinding equipment

Abstract

The invention discloses ultrasonic-assisted fluid cavitation grinding equipment. The equipment mainly installs the component in a flow loop, and a pump in the loop drives fluid to pass through an internal channel of the component; the cavitation inducer is mounted on the nozzle, so that the flowing fluid generates bubbles; the bubbles explode in an internal channel of the component to generate high-energy microjet, and the surface of the channel is polished; meanwhile, the ultrasonic generator moves outside the component, the cavitation strength of fluid in an internal channel of the component can be selectively enhanced, and uneven polishing is prevented; the grinding medium in the fluid can further machine the surface of the channel through the abrasion mechanism of the abrasive particles. According to the equipment, the surface smoothness of a component is greatly improved, the impact pressure on the surface of the component is enhanced by increasing the movement speed of a grinding medium, the improvement effect of the grinding medium on the surface quality is greatly enhanced, the number of bubbles is increased, the cavitation strength is enhanced, and the treatment effect on the surface of a channel is greatly enhanced.

Description

technical field [0001] The invention relates to a polishing device in the field of metal component surface polishing, in particular to an ultrasonic-assisted fluid cavitation grinding device. Background technique [0002] 3D additive manufacturing has become an important manufacturing method in the manufacturing industry and is widely used in the aerospace and automotive industries to manufacture components with complex shapes. However, the surface finish of metal parts manufactured by additive manufacturing is generally not high, especially for the internal channels of the parts, further processing is required to reduce the surface roughness. [0003] For the treatment of the surface of the internal channel of the component, traditional machining has the problem of inaccessibility, because the internal channel aperture of the general component is relatively small, so new polishing methods have been proposed for this problem, such as AFM (Abrasive Flow Machining), Chemical ...
