Abstract

The invention discloses a composite ultrasonic elliptical vibratory cutting device. The device consists of an ultrasonic vibrating unit, a cylindrical servo cutter frame, hollow piezoelectric ceramic and a base, wherein a cutter is arranged at the output end of the ultrasonic vibrating unit; the ultrasonic vibrating unit is arranged in the hollow piezoelectric ceramic; the hollow piezoelectric ceramic is arranged in the cylindrical servo cutter frame; the base is arranged on the end part of the cylindrical servo cutter frame; and the cylindrical servo cutter frame is provided with four elastic hinge structures. Due to the design of symmetrical hinges, cylindrical ceramic is prevented from being deviated while driving the cutter; and the processing accuracy of the surface appearance of a nanoscale three-dimensional micro-structure of the cutter is realized through the gapless transmission of the elastic hinges. The ultrasonic vibrating unit adopts two exciting sources with different structures, so that ultrasonic vibration of the cutter in a longitudinal direction and a bending direction is realized during processing. The cutting device of the invention can be suitable for making shark skin imitation structural skin.

Description

technical field

[0001] The present invention relates to a cutting device, more particularly, refers to a composite ultrasonic elliptical vibration cutting device that closely combines the ultrasonic elliptical vibration cutting technology and the fast servo tool holder technology. The cutting device can be applied to Fabricate a sharkskin-like structural skin. Background technique

[0002] Microstructure surface processing is widely used in military, biological, medical and other fields. Especially in the manufacturing of micro-optical components, the ultra-precision machining of the microstructure surface plays a vital role. Existing microstructure surface processing technologies such as biological complexity and laser etching cannot process real three-dimensional microstructure surfaces. Although ultra-precision diamond cutting can process real three-dimensional microstructures, there are serious wear and tear on diamond tools and low efficiency. and other shortcomings. ...
