毕业设计（论文）-落地单臂铣床悬臂设计.docVIP

摘 要 制造业是我国的基础行业，制造业的发展直接影响国家经济的发展，搞好制造业是国家建设的重要任务。设计出铣床能交货周期短，成本低，质量高，生产效率高，更具备市场竞争力是各个公司的重要任务。落地单臂铣床是由南昌凯马工业园自主研发一种铣床，它是一种高效通用铣床，主要用于加工各类大型工件上的平面、沟槽等。可以对以上工件进行粗铣、半精铣，也可以进行精铣。 这次毕业设计，我们小组就是针对落地单臂铣床研究设计。在分工设计中，我主要负责对铣床悬臂的研究工作。除了对悬臂各个零件进行严密的计算校核，确保其完成对所有加工的要求外，另外，因为铣床要生产加工，就要考虑其生产成本和加工方便，适合大量生产等一些外置因素。所以在设计中，还考虑了大量的适合铣床批量生产的要求。此外，通过在凯马对铣床进行现场参观调研的方式，对机床的整体结构有了充分的认识，并且充分借鉴其中的优势，从而对设计进行了整体的优化和补充。 我们设计的落地单臂铣床是主电机功率5.5KW 主轴转速80~500rpm 6级，纵向行程4000垂向行程700横行程1000落地工作台4000X630 设计中充分发挥自己的主观能动性，有效结合自己四年所学的专业知识，在指导老师和同学的精心指导下最终完成了铣床横梁的设计。在巩固专业知识的同时，也增强了自己的动手实践能力。 关键词：丝杆； 导轨；筋板 Abstract Manufacturing is based industry in China, the development of the manufacturing industry directly affect national economic development, improve manufacturing is an important task for state construction. Design the milling machine can delivery cycle is short, low cost, high quality, and high production efficiency, more have market competitiveness is an important task of each company. Be born by the nanchang kay robot milling machine is independently developed a horse industry park milling machine, it is a kind of high efficient general milling machine, mainly used for all kinds of large scale workpiece machining the plane, groove, etc. Can the rough milling, more than half fine milling, also can undertake fine milling. The graduation design, our group is robot for landing study design. Mil In the nature of design, I mainly responsible for the research work of milling machine bracket. In addition to various parts of the cantilever closely calculated, and ensure that the complete to check all the requirement of treatment, in addition, because the production processing, milling want to consider its production cost and process convenient and suitable for mass production and some other external factors. So in design, also considered a lot of suitable for milling batch production requirements. In addition, through in the field of milling machine horse kay investigation methods and to visit the overal
