Problems solved by technology

[0003] In addition, as the cutting force continues to increase, the ultrasonic amplitude may be suppressed. When the cutting force on the tool reaches a certain value, the ultrasonic amplitude superimposed on the tool may disappear.
[0004] It should be pointed out that since the high-frequency vibration vibrometers currently used, such as laser vibrometers, cannot measure the real-time ultrasonic amplitude of the tool during the actual processing of rotating ultrasonic vibration, it is necessary to develop an ultrasonic real-time vibrometer.

Abstract

The invention discloses a novel ultrasonic real-time amplitude online measuring device. The device comprises a fixed base and a vibration meter mounting cushion block, and a laser vibration meter is arranged at the upper end part of the vibration meter mounting cushion block; a base mounting cavity is formed in the lower end part of the fixed base, a movable reflecting mirror driven by a reflecting mirror driving mechanism is embedded in the base mounting cavity, and the reflecting mirror driving mechanism comprises a ball screw, a screw supporting base, a servo motor, a coupler, a linear guide rail and a reflecting mirror fixing base; and the upper surface of the fixed base is provided with a test piece placing area, the fixed base is further provided with a base through hole which completely penetrates up and down and extends in the feeding direction of a tool, the base through hole is in communication with the base mounting cavity and vertically aligned with the movable reflecting mirror, and an opening in the upper end of the base through hole extends to the test piece placing area. By means of the structural design, the device has the advantages of being novel in structural design and high in automation degree, and the ultrasonic amplitude of the tool can be measured in real time in the actual machining process of rotary ultrasonic vibration.

Description

technical field [0001] The invention relates to the technical field of rotary ultrasonic vibration processing, in particular to a novel ultrasonic real-time amplitude on-line measurement device. Background technique [0002] In the process of rotary ultrasonic vibration machining, with the increase of cutting speed, feed rate and back cutting amount, the cutting force on the tool also increases, and the ultrasonic amplitude superimposed on the tool will change at this time. [0003] In addition, as the cutting force continues to increase, the ultrasonic amplitude may be suppressed. When the cutting force on the tool reaches a certain value, the ultrasonic amplitude superimposed on the tool may disappear. [0004] It should be pointed out that since the high-frequency vibration vibrometers currently used, such as laser vibrometers, cannot measure the real-time ultrasonic amplitude of the tool during the actual processing of rotating ultrasonic vibration, it is necessary to de...
