哈尔滨理工大学学士学位论文 - PAGE 10 - - 超声磨削装置 摘 要 带有旋转的超声磨削加工是在原有机械加工磨削的根本原理上，将超声加工的振动和磨削器械混合到一起的新型式加工的方法。该方式保存了原有机械磨削的某些好的特点，有了超声振动的参与，能极大地提升加工时的工作效率，更能对难加工材料磨削表面质量有所改善。这篇论文的意义是研究出旋转超声磨削装置结构，使用这个装置从事一些加工实验。全文主要内容概括如下： 探讨分析旋转超声磨削机构这个装置，材料如何除去的原理。这个装置中去除材料的原理有相同时间具备冲击（磨具上的磨粒对工作件表面的高快速撞击）和磨蚀（旋转的磨削加工工具和进给中的运动可以变为模型化为磨削加工的过程）的作用。 研究并制作一种新型式的旋转超声磨削装置。该结构装置能安装在不同种类的机床上，进行旋转超声磨削加工对常规表面和某些较多样型面的材料。 关键词 超声加工意义；旋转超声磨削；结构设计与校核 Ultrasonic grinding device Abstract Rotary ultrasonic grinding is a new machining method that combines ultrasonic vibration with grinding tools in the basic principle of the original mechanical grinding. This method saves some of the good features of the original mechanical grinding. With the participation of ultrasonic vibration, it can greatly improve the working efficiency and improve the quality of the grinding surface of difficult to machine materials. The significance of this paper is to study the structure of a rotating ultrasonic grinding device and to do some machining experiments with this device. The main contents are summarized as follows: The principle of how to remove material of rotary ultrasonic grinding mechanism is discussed. The material removal principle of this device in the same time (with the impact of abrasive abrasive on the work piece surface high impact and abrasion (fast) rotating grinding tool and feed movement in can be modeled as process of grinding) role. A new type of rotary ultrasonic grinding device is studied and fabricated. The structure can be installed on different kinds of machine tools, and rotary ultrasonic grinding is applied to conventional surfaces and some kinds of materials with various shapes.
