设计简介
摘 要
组合机床是根据具体情况的需要，对机床进行合理的设计，使其满足加工要求。它具有自动化程度较高，加工质量稳定，工序高度集中等特点。目前，组合机床的研制正向高效、高精度、高自动化和柔性化方向发展。
本次设计是完成对铣削组合机床及其工作台的设计，使其满足对减荷阀体的前后两端面的切削加工。首先针对所要加工的零件，对机床进行总体方案设计，确定机床的总体布局。然后对工作台进行设计。在设计工作台时，根据工作台移动速度，确定丝杠转速，并确定进给变速箱传动方案，最后设计工作台结构。

ABSTRACT
Combination machine is based on the specific needs of the machine for a reasonable design to meet the processing requirements. It has a fairly high degree of automation, processing, stable quality, highly centralized process characteristics. Currently, the portfolio machine being developed efficient, high-precision, high automation and flexible direction.
This design is completed right combination milling machine and its stage design, make it responsive to the valve body by the Security Council ends before and after the cutting. First in response to the processing of parts for machine tools for the overall program design, overall layout of the machine. Then the design stage. In the design stage, according to the speed mobile workstations, set screw speed, and to determine the feed Gearbox Drive program final design stage structure.
