摘  要
机械工业是一个国家的重要产业，机械工业的发展无时不刻都在影响着国家经济的发展，人类的进步离不开机械工业的发展。在全球经济发展的大环境下，中国各个行业被其他国家的先进技术影响的同时，越来越多的外国企业和品牌传播到中国已经成为现实。在新的市场需求的推动下，对钻孔进行改良和优化是当务之急。有大型机械加工设备企业对设备的安全指标的有着一定生产的严格要求。在生产设备的企业，充分考虑到在设备运行中可能出现的问题，从而减少噪声污染引起的振动或不当操作设备的现象等。国内钻孔专机的研发及制造要与全球号召的高效经济、安全稳定主题保持一致。钻孔专机的发展与人类社会的进步和科学技术的水平密切相关。    
近期对机械行业中轴、轴承和轴套的使用情况进行了调查，发现在机械行业中轴、轴承和轴套是其中的关键零配件。自然而然在装配中它们的安装也非常平凡。在安装轴、轴承和轴套时如果使用人工钻孔不但劳动强度太大而且相互尺寸不易保证，所以设计一个专用的钻孔专机势在必行。本次的毕业设计课题的是压缩机底座零件钻孔专机的设计。本文介绍了钻孔专机的结构组成、工作原理以及主要零部件的设计中所必须的理论计算和相关强度校验，该钻孔专机的优点是高效，经济，并且安全系数高，运行平稳。采用的总体方案是：在专机上定位好压缩机底座的位置，利用垂直方向的钻孔装置和水平方向上的钻孔装置对压缩机底座进行钻孔。伺服电机与滚珠丝杆通过联轴器连接，进而带动装有螺母的滑板移动，将旋转运动化为直线压入运动。本次钻孔专机的设计，大大地提高了钻孔的工作效率和质量，并且对后续的钻孔专机的开发和研制都有着一定的影响，在某种程度上大大提升了该设备在国内外的竞争力，体现了机械工业重要性这一核心价值。

ABSTRACT
The environment of global economic development, China industries affected by other countries advanced technology at the same time, foreign enterprises and brand spread to more and more Chinese has become an opportunity. Cap pressing machine in industry through a variety of ways have been working with the relevant technology, and constantly improve their own strength and core competitiveness, and narrow the gap with developed countries. In the new market demand, update the sleeve pressing machine is a pressing matter of the moment. The production of pipe pressing machine equipment manufacturing enterprises to fully tap the potential of the market, vigorously develop the sleeves of large low cost pressing special machinery and equipment, plays a positive role in the evolution of automatic assembly, the assembly of mechanical equipment. There is a large pipe equipment on equipment safety index has strict requirements of production.
In the production equipment of enterprises, give full consideration to the possible problems in the operation of the equipment, so as to reduce the noise pollution caused by
R & D and manufacturing of domestic pipe pressing equipment with global appeal, economic, security and stability of the theme consistent. Increase R & D and production pipe pressing equipment of new energy saving, efficient sleeve pressing machine is the trend of development of the industry, but also to meet the needs of the development of domestic infrastructure construction.Sleeve pressing plane is closely related with the development of society and the progress and the level of science and technology. With the development of science and technology, interdisciplinary mutual infiltration, mutual exchanges between the various industry, extensive use of new structure, new materials, new technology, the sleeve  
Recently, the use of machinery industry, bearing and shaft sleeve shaft were investigated, found that the shaft, bearings and bushings in the machinery industry is one of the key parts. Come very naturally in the assembly of the installation is also very simple. In the installation if the use of artificial pressure with not only the labor intensity is too large and the size of each other is not easy to ensure the shaft, bearing and shaft sleeve.
