7、手动控制。这样一方面难以实现高效率的自动化生产，另一方面，工人劳动强度较大，加工质量也难以保证。另外，对于某些有进给量要求的加工，例如在进行钻削加工实验时，要研究进给量的影响规律，采用现有的普通钻床则无法实现。本次设计的五级自动进给钻床，则可以满足上述要求。针对这个毕业设计课题，主要进行了以下设计工作：1）主运动系统的设计。包括主运动转速设计，运动传递、装配结构设计、带轮、传动齿轮等零件的设计和电机选择。2）进给运动系统的设计。包括进给量的设计、进给运动设计、蜗轮、蜗杆和齿轮、齿条等零件设计。3）机床整体结构的设计。

8、包括主轴箱、进给箱、升降机构、工作台等的设计。在设计过程中，充分考虑了机床的经济性、工艺性和实用性等要求，选择了较佳的方案，达到了较佳的效果。36AbstractWiththedevelopmentofscientifictechnology，therequirementtothequalityandproductionrateofthemec
