Double flange supporting device for sleeve of rotary ultrasonic transducer

Abstract

The invention provides a double flange supporting device for a sleeve of a rotary ultrasonic transducer. An inner conical surface of a main shaft and the main shaft are separated and the inner conical surface is arranged on the sleeve, so that the problem that the inner conical surface of the main shaft is hard to process as the inner conical surface is relatively deep is solved. The conical surface of the sleeve is conveniently processed and a required conical surface can be processed. The two groups of conical surfaces are tightly matched at the same time during assembly. By grinding-in of the length of the sleeve, the two groups of conical surfaces are tightly matched at the same time.

Description

technical field [0001] The invention relates to a double-flange support device for an ultrasonic transducer sleeve of a rotating ultrasonic main shaft, belonging to the field of mechanical manufacturing. Background technique [0002] In recent years, with the in-depth research on ultrasonic processing, its processing advantages have gradually emerged. Rotary ultrasonic grinding is a composite processing technology that combines traditional grinding and ultrasonic machining. Such as figure 1 As shown, in addition to the axial ultrasonic vibration of the tool with a certain amplitude, it also performs high-speed rotational motion relative to the workpiece. Using rotary ultrasonic grinding technology can improve the processing quality and processing efficiency of hard and brittle materials. A large number of studies have shown that compared with traditional grinding, rotary ultrasonic grinding can greatly reduce the grinding force, reduce heat generation, reduce energy consu...

AI Technical Summary

Problems solved by technology

[0005] 1. On the inner wall of the cavity of the main shaft, two conical surfaces, one inside and one outside, are made. The inner conical surface is difficult to process, and the inner conical surface is located deep inside the main shaft, and requires high precision. When grinding, the grinding rod Longer, resulting in poor rigidity of the grinding rod and low machining accuracy;

[0006] 2. The two conical surfaces on the ultrasonic transducer are pressed against the two conical surfaces on the main shaft at the same time, which is over-positioned and difficult to assemble. On the inner wall of the cavity of the main shaft, two conical surfaces, one inside and one outside, are made, and the main shaft The distance between the two cones on the upper surface cannot be adjusted, which is not conducive to controlling the tightness of the two sets of cones, that is, it is difficult to make the two sets of cones fit closely at the same time
