XX大学 毕业设计(论文) 变速箱体组合机床及加工底面4个孔夹具设计 所在学院 专 业 班 级 姓 名 学 号 指导老师 年 月 日 摘 要 本课题设计了变速箱箱体钻孔工位移动工作台卧式组合机床多轴箱。在设计中，根据被加工的零件图计算确定了箱体的尺寸大小，通过钻孔工序切削用量的确定，再计算出钻孔工序的切削参数，进而计算动力参数，由动力参数选择了动力箱。然后制定传动方案。根据传动方案及设计需求选定所用的轴、轴承、齿轮、油泵和其它与之配套的零件，并计算出主轴和传动轴的坐标。最后对本设计选用的轴、轴承、齿轮进行了校核。通过本设计实现钻孔在同一机床上加工，同时使用多把刀具并在几个方面对工件进行加工，达到较高的工序集中程度，从而获得较高的生产率。 多轴箱是组合机床的核心部件。它是选用通用零件，按专用要求进行设计的，在组合机床设计的过程中，是工作量较大的部件之一。它是根据工序图和加工示意图所确定的工件加工孔的数量和位置，切削用量和主轴类型设计的传递各主轴运动的动力部件。其动力来自通用的动力箱，与动力箱一起安装于进给滑台，可完成钻，绞等加工工序。本设计实现了孔的一次加工完成， Abstract This subject has certain parts design of drilling horizontal combination machine tools moving workbench workstation Multi-axle Box. In the design, according to the calculated by processing components determines the size of the box, through the drilling process of cutting parameter determination, then calculates the cutting parameters of drilling process, and then calculating dynamic parameters of the dynamic parameter selection, power box. Then driving scheme. According to the transmission scheme and design requirements of shaft, selected bearings, gears, pumps and other ancillary components, and calculate transmission shaft and the coordinates. Through the design on the same machine processing drilling tools, use more in aspects of the work piece machining, achieve high concentration process, so as to achieve higher productivity. Multi-axle box is a combination of the core components of machine tools. It is the choice of generic parts, according to specific design requirements, in combination of machine tool design process, is the workload of one of the larger components. It is based on processes and process schematic diagram of the work piece determined by the number and location of holes, cutting consumption and spindle type of design momentum of our campaign to pass the spindle parts. Its power comes from a common power boxes and power boxes are installed on the feed slide units, to be completed by drilling, twisting and other
