Abstract

The invention discloses a high-efficiency ultrasonic intensified grinding equipment and method. The equipment includes a rotary clamping mechanism and an ultrasonic processing mechanism; the rotary clamping mechanism includes a coaxial rotary clamp and a rotary drive mechanism, and the coaxial rotary clamp and the rotary drive The driving end of the mechanism is connected; the ultrasonic processing mechanism includes an ultrasonic processing seat, an ultrasonic transducer and an ultrasonic tool head, and the ultrasonic processing seat is provided with a vertically penetrating high-efficiency processing cavity, and the inner wall of the high-efficiency processing cavity is from the bottom The upper side is inclined outward, and the angle between the inner side wall and the vertical direction is 25°-35°; in the working state, the abrasive material is placed on the end surface of the ultrasonic tool head extending to the bottom of the high-efficiency machining cavity, and the workpiece The surface to be machined is placed on top of the efficient machining chamber. The invention has the advantages of wide and random impact angles, many impact times and high average impact speed, and can effectively improve the processing efficiency and effect of intensified grinding.

Description

Technical field [0001] The present invention relates to enhanced grinding equipment and methods, specifically to a high efficiency ultrasonic enhanced grinding equipment and methods. Background [0002] Intensive grinding processing is a kind of anti-fatigue, anti-corrosion, anti-wear metal material surface strengthening processing method based on composite processing method, using surface impact or extrusion to make the surface of the material undergo violent plastic deformation, induce the development of internal defects of the crystal into dislocation, sub-grain boundary or grain boundary, causing the surface material grain refinement, improving the surface hardness of the material, while introducing residual pressure stress on the surface of the material, inhibiting the emergence and development of surface fatigue cracks, and improving the fatigue life of the material. [0003] Among them, the use of ultrasonic technology for intensive grinding processing has shown many advan...
