摘要
随着数控技术的发展和普及,加工中心的作用越发突显它的重要性。为进一
步提高数控机床的加工效率,数控机床正向着工件在一台机床一次装夹即可完成
多道工序或全部工序加工的方向发展,因此出现了各种类型的加工中心机床,如
车削中心、镗铣加工中心、钻削中心等等。这类多工序加工的数控机床在加工过
程中要使用多种刀具,因此必须有自动换刀装置,也就是所说的刀库,以便选用
不同刀具,完成不同工序的加工工艺。自动换刀装置应当具备换刀时间短、刀具
重复定位精度高、足够的刀具储备量、占地面积小、安全可靠等特性。
本论文是开发设计出一种体积小、结构紧凑、价格较低、生产周期短的小型
立式加工中心刀库本文。首先介绍了国内外加工中心研究现状及发展趋势,阐明
了本课题研究的目的、意义。然后进一步介绍本小型加工中心刀库总体结构和各
部件方案的选择,并在此基础上进行了小型加工中心刀库的机械结构的设计计算,
主要包括刀盘部件设计(含刀盘,夹块,刀爪),刀库转动定位机构设计(含转臂,
槽轮,滚子,锁止盘),刀库总体机构设计(含轴承套,轴,箱盖,箱体)刀库移
动部分设计。

ABSTRACT
Along with the numerical control technology development and the
popularization, the processing center function reveals its importance even more
further enhances the numerical control engine laths the processing
efficiency, the numerical control engine laths is clamping to the work piece in an
engine laths attire pletes the multi-channel working procedure or plete
working procedure processing direction develops, therefore appeared each kind of type
processing center engine laths, like the turning center, the boring mill processing center,
drills truncates center and so kind of working procedure processing numerical
control engine laths must use many kinds of cutting tools in the processing process,
therefore must have trades the knife installment automatically, also is the knife
storehouse which said, in order to select the different cutting tool, completes the
different working procedure the processing the knife equipment to have
automatically to have trades the knife time short, the cutting tool repetition pointing
accuracy high, the enough cutting tool margin, the area small, safe reliable and so on
the characteristics.
The present paper is the development designs one kind of volume slightly, the
pact, the price is low, production cycle short small vertical processing
center knife storehouse this introduced the domestic and foreign
processing center research present s
