| 摘要在过去几十年了，机床取得了快速的发展，机床加工的精度不仅越来越高，机床加工效率也是逐年提高。机床的发展影响着制造业，制造业是国民收入的主要部分，制造业的兴衰也是一个国家工业的晴雨表。自工业革命以来，工业正在逐渐取代农业等其他行业，成为国家经济的脊梁。我国与发达国家的差距在这方面更是明显，日本，美国，法国，德国等占据了世界机床一多半，在机床消费方面也是与别的国家有较大的差距。日本机床的数控化普及的很快，数控机床所占机床的比例也比较高，数控机床不仅加工周期比较短，加工精度也比较高。我国加入世贸组织之后，面临环境也越来越复杂，竞争也越来越激烈，这就使得我在必须创新机床机械装备方面的技术。这是缩小我国与发达国家差距的唯一途径，也是我国机械装备发展的趋势。先进的机械装备能提升工艺品的品质质量和精度也会降低加工成本，所以我国制造业发展的首要问题仍旧是工艺、装备技术更加纯洁。本设计主要是对组合机床的设计以及PLC控制的设计，在设计中要通过对典型零件的加工，实现对其单缸泵泵体进行加工竖直孔的目的，同时采用先进的PLC控制方法实现对本次设计机床的电气控制。46299 ABSTRACT In the past few years, the machine has achieved rapid development, precision machining is not only increasing, machining efficiency is also increased every year. Development of the machine affecting manufacturing, manufacturing industry is a major part of the national income, the rise and fall of manufacturing industry is a barometer of a country. Since the industrial revolution, the industry is gradually replaced by agriculture and other industries, has become the backbone of the national economy. The gap between China and developed countries in this respect is even more evident, Japan, the United States, France, Germany accounted for more than half the world's machine tool, but also a larger gap with other countries in machine tool consumption. Japanese machine tool CNC popularity quickly, the proportion of CNC machine tools, machine tools share is relatively high, not only CNC machine tools processing cycle is relatively short, relatively high precision. After China's accession to WTO, facing the environment has become increasingly complex, more intense competition, which makes me have innovative aspects of the technology of machine tools and equipment. This is a narrow gap between China and developed countries, the only way is the trend of China's machinery and equipment development. Advanced machinery and equipment can improve the quality and accuracy of quality crafts will reduce processing costs, so the most important issue of our manufacturing industry is still technology, equipment technology is more pure. This design is a combination of machine tool design and PLC control design, in the design process through the typical components, to achieve the purpose of its single-cylinder pump body processing vertical hole, while the use of advanced PLC control approach the design of the electrical machine control. 目 录 第一章 工艺过程的制定以及对零件图的分析 1 1.1首先选择毛坯论文网，对单缸泵泵体的结构进行分析 1 1.2制定工艺过程 1 1.3对需要加工的工序进行确定 2 第二章 组合机床的设计 4 2.1组合机床的特点 4 2.2组合机床的设计步骤 4 2.3绘制被加工零件工序图 4 2.4绘制加工示意图 5 2.5选择刀具、主轴类型及导向 5 2.6 机床联系尺寸总图的绘制 10 2.6.1机床联系尺寸总图表示的内容 10 (责任编辑：qin) |
