前言
毕业设计是按照教学计划的规定,必须进行的一个重要的综合性教学环节,使学生所学的知识在实践中得到具体应用。通过这次设计,能使学生全面了解和掌握一些机械设备方面的知识,便于使自己形成一套设计的思维模式,而且使所学的知识系统化地由理论转向实践,以培养学生对知识的综合运用能力,为毕业后走上工作岗位打下一个良好的基础。同时通过认真的设计,可以提高学生分析和解决问题的能力,以便更好的适应社会。
本设计的主要内容有:组合机床的概述、组合机床通用部件及其选用、组合机床总体设计、组合机床主轴箱设计、组合机床技术设计五个部分。
摘要
组合机床使用系列化、标准化的通用部件和少量的专用部件组成的多轴、多刀、多工序、多面或多工位同时加工的高校专用机床,其生产率比通用机床高几倍至几十倍,可进行钻、镗、铰、攻丝、车削、铣削等切削加工。组合机床的通用部件和标准件约占70-80%,这些部件是系列化的,-30%的专用部件是由被加工零件的形状,轮廓尺寸,工艺和工序来决定。
在批量生产中这了提高生产率,必须要缩短加工时间和辅助时间,而且尽可能使辅助时间和加工时间重合,使每个装夹多外工件同时进行多刀加工,实行工序高度集中,因而广泛采用组合机床及自动线。
关键词:组合机床,主轴箱,切削
Abstract
Aggregate machine-tool use seriation , the standardized general part and the few special-purpose pose the university special purpose machine which multiple spindle, the multi-knives, the multi-working procedures, the multi-surface or the multi-locations simult
aneously process, its pared to general engine bed high several times to several dozens times, may carry on drills, the boring, the articulation, attacks machinings and so on the silk, turning, milling. The aggregate machine-tool general part and the standard letter pose 70-80%, these parts are the seriation , may carry on the mass productions. Other 20-30% special-purpose part is by is processed ponents the shape, the overall size, the craft and the working procedure decided.
This enhanced the productivity in the volume production, must have to reduce the process period and the non-cutting time, moreover causes the non-cutting time and the process period superposition as far as possible, causes each attire to clamp many outside work pieces simultaneously to carry on the multi-knife processing, implements the working procedure high degree of concentration, thus widely uses the aggregate machine-tool and from generatrix
.
Key word: Aggregate machine-tool, headstock, cutting
