犁刀变速齿轮体钻孔攻丝双工位组合机床双侧4M8设计说明全套CAD图纸.doc

PAGE PAGE 2 摘要 本设计介绍了犁刀变速齿轮箱体多轴箱的设计，其中包含了零件加工工艺的确定，设计中首先要了解工件的加工工艺路线及工序的计算，确定攻螺纹主轴的直径，初步选用电机型号及机床各部分部件。编制三图一卡（被加工零件工序图，加工示意图，机床联系尺寸图，机床生产率计算卡）。在多轴箱设计中，确定传动系统，计算主轴坐标，传动部件的校核及主轴箱的总图绘制。 本设计将钻孔、攻丝两工艺结合为一体，降低了机器成本，而且节省了加工时间，提高了工作生产效率。 关键词： 齿轮箱体 组合机床 总体设计 攻丝多轴箱 ??????? Abstract The design on the Lidao Biansuchilun Box axlebox more than the design, which includes parts of the processing technology of identification, design is first necessary to understand the workpiece in the processing line and process of calculation to determine Tapping the spindle diameter, the initial choice of motor Model and some parts of the machine. Figure 1 of the three cards (the processing parts process map, diagram processing, machine tools Contact size map, machine tool productivity calculation card). In multi-axle box design, drive system established to calculate coordinates spindle, transmission parts of the spindle box and check the total mapping. This design will be drilling, tapping combination of the two as one and reduce the cost of machinery, processing and save time, improve the work efficiency of production.
