摘要
本次设计任务是S1105柴油机箱体制造工艺规程及专用钻床设计，主要内容是：首先对箱体零件工艺设计，在分析了S1105柴油机箱体的具体结构及加工技术要求的基础上，通过批量生产的分析确定箱体各部位的加工方案，并找寻最适合的工艺方案。根据每道工序的技术要求，选定每道工序的背吃刀量、进给量、切削速度以及所采用的机床、刀具、夹具等，确定每道工序的时间，从而绘制工艺过程卡片。然后是对专用钻床夹具体进行设计，根据被加工零件的结构特点、加工尺寸和精度要求，确定组合钻床的配置方案，对专机进行总体设计即三图一卡的设计，三图一卡包括零件工序图、加工示意图、机床联系尺寸图和机床生产率计算卡。其次绘制其装配图和相关的零件图。
整个加工过程均选用组合机床，夹具选用专用夹具，夹紧方式一般都选用液压夹紧，夹紧方式可靠。因此生产效率比较高。适用于大批量、流水线生产加工。能够满足设计的要求。

Abstract
 This design task is the design of the S1105 diesel chassis manufacturing process specifications and the special drilling machine, the main elements are: First, the analysis on the basis of cabinet parts, S1105 diesel cabinet structure and processing requirements of the process design by massanalysis to determine if the processing box programvarious parts, and find the most appropriate technology solutions. According to the requirements of each process technology, the choice, each process of the back of the cutting, feed rate, cutting speed and machine tools, cutting tools, jigs, etc., to determine the time of each process, thereby drawing process card. Then have to deal with the parts of the structure characteristics, the design of a special drilling machine specific file folder, processing size and accuracy requirements, determine the drilling machine configuration combined, the overall design of the three cards, graphic design, three-card, including parts processing diagram, process chart, machine contact, dimensional drawings and machine productivity calculation card. Secondly, the assembly drawing and parts diagrams.
      The whole process of the special fixture, machine tool and fixture selection, selection, clamp commonly used hydraulic clamping, the clamping style is reliable. Therefore, it has the relatively high production efficiency. It is suitable for high-volume, assembly line production and processing. So it is able to meet the design requirements.
