摘 要
组合机床是根据工件加工需要,以大量通用部件为基础。配以少量专用部件组成的一种高效率专用机床。
本次设计的是汽缸体双面钻孔组合机床,汽缸体是发动机的主要部件,属于大批大量生产的零件,从经济性上考虑,为适应生产需求采用组合机床较为合理。根据组合机床的特点,设计步骤主要包括:调查研究、总体方案设计、技术设计、工作设计。
调查研究:根据被加工零件图样,研究其尺寸、形状、材料、硬度、重量、加工部位的结构及加工精度和表面粗糙度要求等内容。同时深入调查了解生产现场状况。总之,通过调查研究应为组合机床总体设计提供必要的大量的数据、资料,做好充分的、全面的技术准备。
总体方案设计:组要包括制定工艺方案、确定机床配置形式、制定影响机床总体布局和技术性能的主要部件的结构方案。总体设计的具体工作是编制“三图一卡”,即绘制被加工零件工序图、加工示意图、机床尺寸联系图,编制生产效率计算卡。
技术设计:根据总体设计已经确定的“三图一卡”,设计机床个专用部件正式总图,如设计夹具、多轴箱等装配图以及根据运动部件有关参数和机床循环要求,设计液压和电气控制原理图。
工作设计:当技术设计通过审后即可展开工作设计,即绘制各个专用部件的施工图样、编制各个部件零件明细表。
通过以上设计步骤,本次设计的汽缸体双面钻孔组合机床充份满足了生产需求,达到了预期的设计目标。

Cylinder body Drilling Modular Machine Tools Design
ABSTRACT
Machine Tool is required under the workpiece, based on a large number of common components. Accompanied by a small amount of the composition of specific parts of a machine tool with high efficiency.
The design of the cylinder body combination double drilling machine, cylinder body is the main engine components, is a large number of mass-produced components, from the economy be considered, to meet the production needs of combination machine tool is reasonable. Machine according to portfolio characteristics, the design steps include: research, overall program design, technical design, job design.
Research: According to the parts to be machined patterns, to study the size, shape, material, hardness, weight, structure and machining parts machining accuracy and surface roughness requirements and so on. Also in-depth investigation to find out about on-site conditions. In short, through the research design should provide the necessary combination of machine tool large amounts of data, information, and make full and comprehensive technical preparation.
Overall Design: Group program to include the development process to determine the tool configurations, the machine tool to develop the overall layout and technical performance of the main components of the structure of the program. Overall design of the concrete work is the preparation of the "three plans a card", drawn by processing parts that process map, process diagram, machine size contact map, the preparation of production efficiency calculation card.
Technical design: According to the overall design has been identified "three map one card" design tool dedicated official general plan components, such as the design of fixtures, and other multi-axle box assembly diagram and the parameters under the moving parts and machine cycle requirements, design of hydraulic and electrical control schematic.
Work Design: When the technical design through post-trial to begin work as designed, or drawn construction drawings of various specific components, the preparation of the various components parts list.
The above design steps, this design of cylinder body Drilling Modular Machine Tools fully meet the production needs to reach the desired design goals.
KEY WORDS: machine tool, the three plans for a card, multi-axle box, fixture

组合机床是一种专用高效自动化技术装备,由于它仍是大批量机械产品实现高效、高质量和经济性生产的关键装备,因而被广泛应用于汽车、拖拉机、内燃机和压缩机等许多工业生产领域。其中 ,特别是汽车工业,是组合机床最大的用户。如德国大众汽车厂在Salzgitter的发动机工厂,90年代初所采用的金属切削机床主要是组合机床自动线(60%)、组合机床(20%)和加工中心(20%)。显然,在大批量生产的机械工业部门,大量采用的设备是组合机床。因此,组合机床的技术性能和综合自动化水平,在很大 程度上决定了这些工业部门产品的生产效率、产品质量和企业生产组织的结构,也在很大程度上决定了企业产品的竞争力。
现代组合机床为机电一体化产品,它是控制、驱动、测量、监控、刀具和机械组件等技术的综合反映。近20年来,这些技术有长足进步,同时作为组合机床主要用户的汽车和内燃机等行业也有很大的变化,其产品市场寿命不断缩短,品种日益增多且质量不断提高。这些因素有力地推动和激励了组合机床和自动线技术的不断发展。
十多年来,作为组合机床重要用户的汽车工业,为迎合人们个性化需求,汽车变
