摘要组合机床是加工一些零件的快捷且常用的机床之一，二多轴箱是组合机床的主要部件。钻Ф12（或者Ф14）孔的组合机床的多轴箱是根据具体的零件——支撑座而设计。它的出现大大提高了生产的效率和加工质量。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。49553

Abstract   The Building-block Machine is a kind of special machine.It is often used to process components.Multiple Spindle Case is the major part of the Building-block Machine.The project of the Multiple Spindle Case which is used to drill Ф12(or Ф14) depends on a pationlar part -support bed.It improve product efficiency and quality. During the course of design, the size of the box is calculated according to the drawing of the refined machine part. Through fixing the machining parameters by the drilling process can we calculate the cutting parameter of the drilling process. Then, we can calculate dynamic parameters and choose the power box. After that, we lay down the transmission scheme. We choose axis, bearing, gear, gasoline pumps and other matching element according to the transmission scheme and design requirement and calculate the coordinate of main spindle and drive shaft. At last, we check the axis, bearing, and gear. We will achieve that drilling can be processed on the same machine tool and we can use more than one cutting tool to process the workpiece on several aspects. Therefore, through a higher density of the procedure can we obtain a superior productivity.

Key words: Multiple Spindle ，Case;Spindle，Transmission，Shaft;Programmable Logic Controller.
