1、毕业设计泵盖钻孔组合机床设计摘要我的毕业设计题目是：泵盖钻孔组合机床设计组合机床是以通用部件为基础，配以少量的专用部件，对一种或若干种工件按预先确定的工序进行加工的机床。设计过程包括被加工零件的工艺分析，机床配置形式的选择，切削用量的确定，刀具的选择，组合机床的总体设计，多轴箱齿轮的排布。此外，我还绘制了4张图纸，分别为工序图，加工示意图，机床联系尺寸图，多轴箱图，还有一张生产率计算卡。我本次设计的重点是多轴箱的设计，多轴箱是组合机床的重要组成部分，它是选用通用部件，按专业要求设计的，其用于布置机床工作主轴及其传动零件和相应的附加结构的

2、，它通用按一定速度比排布传动齿轮，把动力以动力部件—动力头、动力箱、电动机等、传递给各个工作主轴，使其获得所要求的转速和转向等。在总体的设计过程中，对机床的夹具方案也有所考虑，选择合理的定位方式，保证工件位置正确且装卸方便，且保证夹具结构简单成本低，从而体现组合机床自动化程度高，生产效率高，产品质量稳定，劳动强度低，结构稳定，工作可靠，使用和维修方便等特点。关键词：组合机床工艺方案生产率多轴箱32Title:BoreholePumpCoverCombinationMachineBedDesignAbstractMytopicofdesi
