A five-axis three-dimensional ultrasonic polishing machine tool and using method thereof

Abstract

The invention discloses a five-axis three-dimensional ultrasonic polishing machine tool which is improved on the basis of the existing five-axis two-dimensional ultrasonic polishing machine tool composed of a rack, an X-direction moving mechanism, a Y-direction moving mechanism, a Z-direction moving mechanism, an ultrasonic vibration polishing device, a rotary workbench, an ultrasonic atomization application device for a polishing solution and an online workpiece detecting device, one-dimensional ultrasonic vibration originally adopted by the ultrasonic vibration polishing device is changed into two-dimensional ultrasonic vibration, the two-dimensional ultrasonic vibration is completed by two ultrasonic devices and a polishing head base, the two ultrasonic devices are mounted on a vertical rotary table, the included angle of the two ultrasonic devices can be adjusted by a station adjusting hole, the polishing head base is connected with amplitude-change rods of the ultrasonic devices, and a polishing head is fixedly arranged on a base. According to the ultrasonic polishing machine tool, the two-dimensional ultrasonic vibration is applied to the polishing head, and due to the adoption of two-dimensional ultrasonic coupling, not only can the polishing power be improved, but also the movement locus of the polishing head uniformly covers a processing region in a curved reciprocated bypassing way, so that the polishing efficiency is remarkably increased.

Description

technical field [0001] The invention relates to a polishing machine, in particular to a five-axis three-dimensional ultrasonic polishing machine tool for complex curved surface polishing and a method for using the same. Background technique [0002] With the development of industrial technology, hard and brittle materials have shown broad application prospects in the fields of aerospace, automobiles, molds, optics, and semiconductors. Optical glass is often used to make reconnaissance satellite camera lenses, stealth radar search mirrors, high-speed aircraft windows, large mirrors for astronomical telescopes, and optical lenses and prisms in laser emitting devices. Conventional machining of optical elements of hard and brittle materials is very difficult, and is usually obtained through ultra-precision grinding, polishing and ultra-precision grinding, but this method takes a long time and costs a lot. In order to solve this processing problem, an ultrasonic polishing proces...

AI Technical Summary

Problems solved by technology

Although this ultrasonic polishing machine tool solves the above-mentioned technical problems existing in the existing ultrasonic polishing machine tools, the one-dimensional ultrasonic vibration applied to the main shaft can only make the polishing head do reciprocating linear motion along the main shaft direction, and the polishing power is low. During processing, the movement trajectory of the polishing head is only a single point on the complex surface, and the processing efficiency is not high enough
