Embodiment Construction

[0024] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0025] See figure 1 As shown, a longitudinal torsion ultrasonic vibration processing device includes an ultrasonic vibrator and an horn. The horn can convert the longitudinal ultrasonic vibration provided by the ultrasonic vibrator into longitudinal and circumferential longitudinal torsional composite vibration. The horn is directly connected to one end of the ultrasonic vibrator. The horn and the ultrasonic vibrator are directly connected to form a whole, which can avoid the loss of ultrasonic energy when transmitting between the two components.

[0026] The horn includes a first-stage horn 9 and a second-stage horn for fixing processing tools. One end of the first-stage horn 9 is connected to one end of the sec...

Abstract

The invention provides a longitudinal-torsion ultrasonic-vibration processing device, which comprises an ultrasonic vibrator and an amplitude-change pole converting longitudinal ultrasonic vibration provided by the ultrasonic vibrator into longitudinal-torsion compound vibration. The amplitude-change pole is connected with one end of the ultrasonic vibrator, and comprises a first-stage amplitude-change pole and a second-stage amplitude-change pole; the first-stage amplitude-change pole is hollowly cylindrical; the second-stage amplitude-change pole is fixed at one end of the first-stage amplitude-change pole, and is used for fixing processing tools; the inner diameter of the first-stage amplitude-change pole is greater than one half of the outer diameter of the first-stage amplitude-changepole; and a plurality of spiral grooves penetrating a cylinder wall are formed on the cylinder wall of the first-stage amplitude-change pole. The longitudinal-torsion ultrasonic-vibration processingdevice is high in energy conversion and transmission efficiency.

Description

Technical field [0001] The invention relates to a cutting processing device, and more specifically, to a longitudinal torsion ultrasonic vibration processing device. Background technique [0002] Ultrasonic machining is a special machining method that applies high-frequency vibration to the tool or workpiece. Because of its characteristics of low cutting force, good machining quality, and low tool wear, it has been widely used in hard and brittle materials and difficult-to-machine materials. In rotary ultrasonic vibration processing, the tool vibrates at a high frequency and a small amplitude while rotating with the spindle of the machine tool at a high speed, which changes the processing and removal mechanism of hard and brittle materials such as glass, ceramics, and composite materials. Therefore, there is obvious in the processing of this type of material. The advantages. The current rotary ultrasonic vibration processing generally uses longitudinal ultrasonic vibration. Ordi...
