XX 学院毕业设计(论文) 法兰机械加工工艺及夹具设计班级专业教学系指导老师完成时间年月日至年月日 XX 学院毕业设计( 论文)法兰机械加工工艺及夹具设计 I 摘要本次设计的主要内容是法兰机械加工工艺及夹具设计,法兰主要是与其它零件配对使用,其主要加工表面及控制位置为 ??外圆和99 .35 ?内孔。由零件要求分析可知, 保证 ??外圆和99 .35 ?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 ?大外圆粗定位夹紧加工后,对 ??外圆进行车削加工同时成型。因其粗糙度为 ,可通过粗车、半精车满足。对于车削 99 .35 ?内孔时,主要以法兰的 96 ?凸台定位,控制其自由度,以达到加工出来的产品满足要求并且一致性好的目的。本文的研究重点在于通过对法兰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、省力的夹具以及设计出简单、实用的数控加工程序, 通过实践验证,最终加工出合格的法兰零件。关键词: 法兰,加工余量,工艺,夹具 XX 学院毕业设计( 论文)法兰机械加工工艺及夹具设计 II A bstract Enable producing the target in process of production raw materials, the blank , state of quality and quantity on part e always take place direct course of change ask craft course, if the blank is made, machining, heat treatment , assemble etc. and call it the craft course. In the course of making the craft , is it confirm every erector location and worker step that process need this of process to want, the otive of processing , this process , and the entering the giving amount of the lathe, cut depth , the rotational speed of the main shaft and speed of cutting, the jigof this process, the cutter and measuring tool, aone hundred sheets of number of times still leaves and aone hundred sheets of length leaves, calculate basic time of this process , auxiliary time and service time of place of working finally. At present, part of the processing of domestic have begun to close to the machine tool, but also need to clamp the workpiece, that is to say, although the technology has been greatly improved but his nature has not changed much, on the flip side, because of his skill and precision is high, soa high quality tool holder of machine tools is an absolute necessity. As everyone knows, because our technology in the unceasing development, technical requirements for processing of the knife is also more and more high, before an ordinary lathe is clamped four tool, and now there isa large number of will not meet the work requirements, the
