Oval ultrasonic machining device with non-contact induction power supply function

Abstract

The invention provides an oval ultrasonic machining device with a non-contact induction power supply function. The oval ultrasonic machining device is composed of an induction power supply device and an oval ultrasonic tool handle. The induction power supply vice sides of the induction power supply device are fixed to a BT tool handle shell of the oval ultrasonic tool handle. The induction power supply primary sides of the induction power supply device are arranged on the outer side of the oval ultrasonic tool handle and are arranged in an internal-external concentric circle mode. The gap between the two induction power supply primary sides is kept small. The induction power supply primary sides are fixed to a spindle seat of a numerical control machining center machine tool through a bracket and kept static. The oval ultrasonic tool handle is fixed a spindle of the numerical control machining center spindle through a taper shank and rotates at a high speed along with the spindle. By adoption of the oval ultrasonic machining device, the rotary radius of the oval ultrasonic tool handle is decreased, the rotary inertia of the oval ultrasonic tool handle is lowered, rotary stability of the oval ultrasonic tool handle is improved, and the oval ultrasonic machining device can avoid the working space of a tool replacing manipulator and meet the automatic tool replacing condition under the condition that the structure of the spindle of the numerical control machining machine tool is not changed. The structure is simple, and operation and use are convenient.

Description

Technical field [0001] The invention relates to an ultrasonic processing device, in particular to an elliptical ultrasonic processing device with non-contact induction power supply. It belongs to the field of ultrasonic processing technology. Background technique [0002] Ultrasonic processing technology is a special processing method that combines ultrasonic vibration to achieve material removal based on traditional cutting processing. Compared with traditional cutting processing, ultrasonic processing can reduce cutting force, cutting temperature, reduce tool wear, and improve surface accuracy. Therefore, it is suitable for the processing of various difficult-to-process materials and difficult-to-process structures, especially for the finishing of hard and brittle materials such as ceramics and glass and carbon fiber composite materials. [0003] There are two types of vibration in ultrasonic machining: single-phase vibration and elliptical vibration. Elliptical vibration is t...
