Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] The invention relates to a split-type double-flange support device for a rotating ultrasonic transducer. It is part of the high-speed rotating ultrasonic grinding spindle. Under the support of two flanges, the ultrasonic transducer rotates stably at high speed (10000rpm) with the main shaft.

[0022] Figure 5 The main shaft (5) shown in is composed of a left main shaft (501) and a right main shaft (502). After the main shaft is rough-machined, the main shaft is divided into two by wire cutting; the taper surface and the joint are processed on the two main shafts respectively; the two main shafts are tightened, and then the inner and outer surfaces of the main shaft are finished. The ultrasonic transducer (4) is composed of a front cover horn (401), a piezoelec...

Abstract

The invention provides a split-type double-flange supporting device for a rotary ultrasonic transducer. Two conical surfaces need to be machined on a spindle for supporting the double-flange ultrasonic transducer, while an inner conical surface of the spindle is deep and consequently difficult to machine. According to the split-type double-flange supporting device, the spindle is divided into two parts, so that the problem that the inner conical surface of the spindle is difficult to machine is solved; and two groups of conical surfaces are matched closely synchronously by grinding-in the lengths of two sections of the spindle.

Description

technical field [0001] The invention relates to a split-type double-flange support device for an ultrasonic transducer 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 c...
