摘要数控加工中心作为近年来机械行业内高速发展起来的一种新型装备加工设备。已经受到了各个传统制造强国和兴起发展中国家的高度重视。这种高集成度的新型加工装备集成了许多车床、镗床、铣床、刨床等传统单一加工装备的功能和作用。近年来，在机械行业内起到了很大的主导作用。我所研究的数控加工中心的刀库在其中起到了许多关键性的作用，顾名思义刀库的最基本作用便是储存各种类型的刀具，以便在进行复杂零件加工时提供刀具，第二层含义便是换刀，换刀的重要意义就在于节省大量时间缩短加工准备的时间提高加工效率。69499
这次我的课题是加工中心的链式刀库的设计。在图书馆查阅相关刀库的资料和机械手册后，我对刀库的总体传动设计方案进行理论设计和理论验证，对电机种类和电机基本参数进行了确定，对蜗轮蜗杆等主要零部件进行参数计算设计以及验证；最后我使用AUTO CAD计算机绘图软件绘制了总装配图和重要零部件的结构工程图。

Abstract CNC machining center is based on the traditional machine tool developed mechanical equipment, can be used to process different shapes of parts.Under the developmet of manufacturing,More and more enterprises began to use CNC equipment. The machining center is a kind of CNC machine tool with automatic tool changer, which can carry out high speed and high precision machining of parts such as car, milling and boring. Which is used to store the tool magazine, knife library stored in a variety of tools can make the processing center alone processing complex parts.
The main content of this graduation design is CNC machining center chain magazine design. The magazine system is an indispensable part of the machining center and is a guarantee that the machining center completes its function. Machining center of the magazine system design is the collection, machine, gas, etc. as one of the integrated design. After the access to information, the overall program of the magazine to choose, compare and determine the choice of the motor, the worm and other major components of the design and calculation; drawing the assembly diagram and the main parts and components, and so on.
Through this design of the automated processing equipment have in-depth understanding, in the consolidation of knowledge has been based on the improvement of our own practical ability.
