摘要
90年代以来,数控加工技术得到迅速的普及发展,高速加工中心作为新时代数控机床的代表,已在机床领域广泛。自动换刀刀库的发展俨然已超越为数控加工中心配套的角色,在其特有的技术领域发展出符合机床高精度、高效率、高可靠度及多任务复合等概念的独特产品。本课题是链式刀库的总体设计、传动设计、结构设计以及传动部分的运动和动力设计。这种刀库在数控加工中心上应用非常广泛,其换刀过程简单,换刀时间短;总体结构简单、紧凑,动作准确可靠;维护方便,成本低。本课题的目的就是要通过对加工中心刀库的优化设计以提高换刀速度,减少助助时间。
在进行设计时,采用了系统化设计方法,将设计看成由若干个设计要素组成的一个系统,每个设计要素具有独立性,各个要素间存在着有机的联系,并具有层次性,所有的设计要素结合后,即可实现设计系统所需完成的任务。
在借鉴和参考大量有关刀库的机械结构后,结合实际情况,决定采用链式刀库双手式机械手换刀方案,根据机械设计与机械原理等有关知识对加工中心刀库进行设计,采用AutoCAD对刀库及关键零件进行绘制。

Abstract
Since the C machine technology has made the rapid and universial development, as a new era of the representatives of NC machine tools. High-speed processing center has been widely used in the field of machine tools. The development of automatic Tool Chane, tool house in recent years seems to have gone beyond the NC Center for supporting the role of technology in their unique areas of development to meet the high-precision machine tools, high efficiency and reliability, and plex tasks, such as the concept of unique products. The tool house as a processing center one of the most important part, it has a direct bearing on the development of the processing center’s development. This pleted the overall design, transmission design, structure design and the transmission part’s movement and dynamic design of the sword library. Such a tool house in C Machine Center is widely used, the tool change is simple,, tool change time is short; overall structure is simple pact. Action is accurate and reliable; convenient maintenance and low cost.
The purpose of this project is to improve the speed of the tools change and reduce auxiliary time through the optimization design of the JCS-013 type NC horizontal boring and milling machine tool store.
In developing the design, I have adopted the systematic design method. The design is regarded as a system which is consisted of several design elements. Each design elements is in depend , but there
