半轴壳体左右两面孔加工组合机床总体设计
摘 要
半轴壳体左右两面钻孔组合机床总体设计是根据加工零件，拟定工艺和结构方案，选择合适的刀具，拟定合适的结构方案和工艺，定出通用部件，并进行绘图和相关方案和技术文件的设计。
满足加工内容如下：对左右端面经行钻孔加工，左端面上孔径为23.4mm和17.4mm的孔各两个，右端面上是孔径为13mm的六个孔。组合机床总体设计和普通机床的设计过程是相似的，组合机床使用多刀同时加工的，因此自动化程度高，因而比普通机床生产效率高，产品质量高，所需劳动力少。组合机床的总体设计是通过对零件分析等，用三图一卡表达出总体方案，包括绘制零件加工的工序图、加工示意图、联系尺寸图，及生产率计算卡。设计组合机床满足生产要求，符合实际情况，并且节约材料，满足市场需求，经济实惠。

HALF SHAFT CASING AROUND TWO FACE PROCESSING AND THE OVERALL DESIGN OF COMBINED MACHINE TOOL
ABSTRACT
Overall design about half shaft shell sides drill combination machine tools is according to the machining parts, drafting process and the structure scheme, choosing the right tool, to formulate appropriate structure scheme and process, set general components, and for the design of drawing and relevant scheme and technical documents.
About satisfy processing content is as follows: to end the row drilling processing, on the left end face diameter of 23.4 mm and 17.4 mm hole of the two, on the right end is size for six of the 13 mm hole. Overall design of combined machine tool and the design process of ordinary machine tool is similar, combination machine tools using multiple blade processing at the same time, so a high degree of automation, and thus is higher than common machine tool production efficiency, product quality is high, you need less labor. The overall design of the modular machine tool is based on the component analysis and so on, with three figure one card expresses the overall scheme, including map parts processing process, processing sketch, contact size chart, and productivity calculation card. Design combination machine tools to meet production requirements, in line with the actual situation, and save material, meet market demand, economical and practical.
