毕业设计说明书（论文）中文摘要

　　　从企业实际需求出发，在全面分析被加工零件的结构特点、尺寸精度、被加工孔相互之间位置精度、表面粗糙度和技术要求的基础上，指出采用现有设备不仅工人劳动强度大，生产率低，而且零件加工精度难以保证。根据实际需要，研制出了4孔单工位组合钻床。首先通过分析比较，确定了4孔单工位组合钻床的配置型式及结构的最佳方案，遵循机械设计中标准化、通用化、系列化原则，给出机床的总体设计，绘制出代表机床总体设计的被加工零件工序图、加工示意图、机床联系尺寸图和生产率计算卡。对机床的关键部分:主轴箱和夹具的结构进行了创新设计。由于在这台组合钻床上需同时加工4个孔，虽然间距小，而且孔的排列分散，但是孔的数量不多，可采用常规方法排箱实现孔的工序集中的加工方案。钻床的主轴箱传动系统通过采用推力球轴承和圆锥滚子轴承等结构方面的创新设计，完成排箱设计。组合钻床夹紧机构，采用了移动式压板联动偏心夹紧机构。减少了装卸零件所用时间，提高了生产效率。

Title   Design a combination drilling machine which can boring   screw thread bottom bore in two profiles of the diesel motor cylinder
Abstract
In view of the actual conditions of enterprises and on the basis of overall analyzing workpiece structure features，accuracy of size, surface roug-        hness, accuracy of distance between drilled holes and other technical r-    equirements,  this article points out that the existing equipments used to manufacture workpieces may result in lower productivity,greater inte-      nsity of labour and worse working accuracy. Therefore, it is necessary to develop a new type of 4 hole single working position combination drilling machine.Through analysis and comparison, the article has determined the best project of the structure and the disposition of the 4 holes combination drilling m- achine. According to thepriciple of standardization, genera-        lization and serialization in machine design, the article offers the master design of the drilling machine，the  process  drawing  of workpiece, the working  diagram, the connection dimentional drawing of the drilling mac-    hine and the calulating card of productivity. In some key parts of the drilling machine, there are certain new designs on the structure of the spindle box and the fixture. With 4 hole drilled simultaneously on the drilling machine, in addition to small spacing between holes and dispersive arrangement of hole position, the 4 holes drilling program cannot be com-    pleted in con- ventional way. In the transmission system of 4 hole drilling machine are used some new structural designs such as pin bearings and pos-   ition-change- able gears，so that the arrangement of hole position,which cannot be finished in conventional way, can be accompl- ished. The combina-      tion drilling machine is applied a fast spiral pinch machinery whose fea-    tures are not only shortens the time consumed in loading and unloading workpiece but also enhances productivity.
