Embodiment Construction

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

[0025] see figure 1 As shown, a longitudinal-torsional ultrasonic vibration processing device includes an ultrasonic vibrator and a 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 it is transmitted between the two parts.

[0026] The horn includes a first-stage horn 9 and a second-stage horn for fixing processing tools, one end of the first-sta...

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 present invention relates to a cutting processing device, more specifically, to a longitudinal torsional ultrasonic vibration processing device. Background technique [0002] Ultrasonic machining is a special processing method that applies high-frequency vibration to the tool or workpiece. Due to its characteristics of small cutting force, good processing quality, and small tool wear, it has been widely used in the processing of hard and brittle materials and difficult-to-machine materials. In rotary ultrasonic vibration machining, the tool rotates at a high speed with the spindle of the machine tool while vibrating at high frequency and small amplitude, which changes the removal mechanism of hard and brittle materials such as glass, ceramics, and composite materials. Therefore, it has obvious advantages in the processing of such materials. The advantages. The current rotary ultrasonic vibration machining generally adopts longitudinal ultrasonic v...
