内容简介：

超声磨削装置摘 要旋转超声磨削是在传统机械磨削的基础上，将超声振动加入到磨削工具上的一种新型的复合加工方法。该方法不仅保留了传统机械磨削的一些优良特性，又因加入超声振动后，能较大地提高加工效率，有效地改善工程陶瓷、复合材料等难加工材料磨削表面质量。本文旨在研制出旋转超声磨削装置，并利用该装置进行了一些实验研究。全文主要内容概括如下：1. 讨论分析了旋转超声磨削的材料去除机理。旋转超声磨削中材料去除机理同时具有冲击（磨具上的磨粒对工件表面的高频高速冲击）和磨蚀（磨削工具的旋转和进给运动可模型化为磨削过程）两种作用。2. 研制了一种新型旋转超声磨削装置。该装置能以附件的形式安装在数控机床上或普通机床上，进行常见表面、甚至一些较复杂型面的旋转超声磨削加工。关键词：超声加工意义，旋转超声磨削，结构设计与校核，AbstractRotary ultrasonic grinding (RUG) is a new machining method which integrates rotary movement of traditional grinding with ultrasonic oscillation. This method can keep down some excellent grinding characters of Mechanical grinding, greatly enhance process rate and effectively improve the effect of grinding surface of difficult-to-cut materials (stainless steel and composite material and the like). The aim of this paper is that we design and manufacture the grinding device of rotary ultrasonic machining, and carry out some research by using developed develop. The main content of this paper can be sum up as follows: 1. We have analysis the material remove mechanism of RUG, and material remove of rotary ultrasonic grinding conclude on high frequency impact of abrasive particles on grinding tool against work piece and ablation that rotary and in-feed movement of grinding tool can form grinding process.2. A new grinding device of rotary ultrasonic machining have been designed and manufactured. This device can be installed on numerical control machine or common machine tool as an accessory and can carry out rotary ultrasonic grinding for usual surface and even some complicated surface.Key words: ultrasound processing significance ; Rotate ultrasound grind ;Structure design and checking目 录前言11.绪论21.1 超声的发展史21.2超声加工的原理及特点21.3 工程陶瓷材料的使用价值及加工技术31.4超声加工陶瓷的意义及前景72. 设计说明书82.1超声磨削装置的结构设计82.1.1超声加工设备及其组成部分82.1.2初步结构设计82.1.3 结构的比较102.1.4 最后结构的确定112.2 装置中的各部件的设计及校核132.2.1 电机的计算与选择132.
