1、XX学院本科毕业论文(设计)题目钻机泵头加工工艺设计作者学院机械工程学院专业机械设计制造及其自动化学号指导教师二〇一五年四月二十三日摘要本次设计的主要内容是钻机泵头加工工艺设计,钻机泵头其主要加工表面及控制位置为和内孔。由零件要求分析可知,保证和内孔尺寸的同时应该尽量保证其同轴度,这对于后工序装配和总成使用上来说都有重要影响。所以,工序安排时,采取以左视图中大底面粗定位夹紧加工后,对内孔进行镗削加工同时成型。因其粗糙度为Ra6.3,可通过粗镗、半精镗满足。对于钻俯视图中6-M10螺纹孔时,主要以钻机泵头左视图的下部小端面进行定位,控制其自由度,以达到加工出来的产品满足要求并且一致
2、性好的目的。本文的研究重点在于通过对钻机泵头的工艺性和力学性能分析,对加工工艺进行合理分析,选择确定合理的毛坯、加工方式、设计高效、省力的夹具,通过实践验证,最终加工出合格的钻机泵头零件。关键词:钻机泵头;加工余量;工艺;夹具IABSTRACTThelatheismainlyreferstotheworkpiecerotationmovement,mobiletoolsforprocessingintorotarymovementofthemachinetoolsurface.Itcanbeusedforprocessingavarietyofrotaryformingsurfa
