摘  要

根据设计任务书的要求,本设计说明书针对300型阀体机床的设计及专用夹具设计进行说明。要内容包括多轴头工艺方案的制定、多轴头配置型式的选择、多轴头总体设计以及轴箱设计。
全文要包括组合钻床的总体设计和轴箱设计两部分。机床总体设计要是在选定工艺方案并确定机床配置形式、结构方案基础上确定“三图一卡”， 多轴头设计根据“三图一卡”，整理编绘出多轴头原始依据图，重点分析传动系统，经过各种方案的比较，最后确定最优方案。此外，为了提高劳动生产率，降低劳动强度，保证加工质量，需设计专用夹具。

Abstract

According to the requirements of the mission design, design for wallboard machine and special fixture for the design specification is described. The main contents include aggregate machine-tool craft plan formulation, combined machine tool configuration choice, aggregate machine-tool system design and main shaft case design.
The full text mainly includes overall design and main shaft box combination milling machine design two parts. The overall design of machine tool is mainly in the selected process and determine the basis of machine tool configuration, structure scheme to determine the "three charts and a card", the headstock design according to "three charts and a card", reorganizes the compilation to leave the headstock primitive basis chart, the key analysis transmission system, through the comparison of various schemes, and finally to determine the optimal scheme. In addition, in order to improve labor productivity, reduce labor intensity, guaranteed the processing quality, need to design special jig.
