本文着重讲述了机械行业的现状和发展趋势,转速器盘的用途,机械加工工艺规程的作用及内容以及夹具设计。随着科学的日益发展进步和国家产业政策的调整,工程机械行业已成为没有政策壁垒的完全竞争行业。关键词 工艺规程 加工工艺 夹具设计 1机械行业的现状和发展趋势机械工业是国民经济的装备产业,是科学技术物化的基础,是高新技术产业化的载体,是国防建设的基础工业,也是为提高人民生活质量提供消费类机电产品的行业。机械工业具有产业关联度高,需求弹性大,对经济增长带动促进作用强,对国家积累和社会就业贡献大等特点。各工业化国家经济发展的历程表明,没有强大的装备制造业,就不可能实现国民经济的工业化、现代化和信息化。目前装备制造业发展滞后是制约我国经济发展和产业升级的重要因素,加大结构调整力度,推进机械工业持续、健康、稳定发展,对于转变经济增长方式,提高国民经济整体素质,增强我国经济的国际竞争力,保障国防安全等都具有重要而深远的意义。 目前机械工业全行业拥有企业3.97万个,其中工业联合会系统企业2.99万个,从业人员1118.1多万人。从事6大类、48中类、205小类产品的生产。全国规模以上机械工业企业总产值完成28489亿元,同比增长25.12%;按90年不变价计算的总产值完成28206亿元,同比增长23.39%。这一增长速度比同期全国工业增速15.70%和18.90%分别高9.42个百分点和4.49个百分点,居工业各行业之首。全行业实现的净利润和交纳的税金也分别达到了831.1亿元和694.8亿元。这是机械工业持续五年增长,而且是我国机械行业历史上罕见的高速。机械工业经过改组,多种成分共同发展、相互促进的局面已基本形成。民营资本主要经济指标已占机械行业的40%,三资企业主要指标占全行业的30%左右,而利润和出口交货值分别超过全行业的50%和60%。2转速器盘的用途转速器盘从整体上来说,其径向尺寸比轴向尺寸大,因此,可以将其划定为不规则的盘类零件。零件上直径为10mm的孔装一偏心轴,此轴一端通过销与手柄相连,另一端与油门拉杆相连。转动手柄,偏心轴转动,油门拉杆即可打开油门(增速)或关小油门(减速);两个直径为6mm孔装两个定位销,起限位作用。手柄可在120内转动,实现无级变速。转速器盘通过两个直径为9mm的螺栓孔用M8螺栓与柴油机机体相连。3机械加工工艺规程的作用及内容机械加工工艺规程的主要作用:机械加工工艺规程是生产准备工作的主要依据。根据它来组织原材料和毛坯的供应,进行机床调整,专用工艺装备的设计与制造,编制生产作业计划,调配劳动力,以及进行生产成本核算等。机械加工工艺规程也是组织生产、进行计划调度的依据。有了它就可以制定生产产品的进度计划和相应的调度计划,并能做到各工序科学地衔接,使生产均衡、顺利,实现优质、高产和低消耗。机械加工工艺规程是新建工厂的基本技术文件。根据它和生产纲领,才能确定所需机床的种类和数量、工厂的面积、机床的平面布置、生产工人的工种、等级和数量、以及各辅助部门的安排等。机械加工工艺规程包括的内容是机械加工工艺过程卡片和机械加工工序卡片,是两个主要的工艺文件。机械加工工艺过程卡片,是说明零件加工工艺过程的工艺文件。在单件、小批量生产中,以机械加工工艺过程卡片指导生产,过程卡的各个项目编制较为详细。机械加工工序卡片是为每个工序详细制定的,用于直接指导工人进行生产,多用于大批量生产的零件和成批生产中的重要零件。制订机械加工工艺规程的步骤如下:根据零件的生产纲领决定生产类型;分析零件加工的工艺性;选择毛坯的种类和制造方法;拟订工艺过程;工序设计;编制工艺文件。4夹具设计在机床上装夹工件所使用的工艺装备称为机床夹具。夹具是机械加工不可缺少的部件,在机床技术向高速、高效、精密、复合、智能、环保方向发展的带动下,夹具技术正朝着高精、高效、模块、组合、通用、经济方向发展。机床夹具由定位元件、夹紧装置、对刀及导引元件、连接元件、夹具体、其他装置或元件组成。定位元件、夹紧装置和夹具体是夹具的基本组成部分。按夹具的应用范围分类有通用夹具、专用夹具、成组夹具、组合夹具等;按夹具上的动力源分类有手动夹具、气动夹具、液压夹具、电动夹具、磁力夹具、真空夹具、切削力及离心力夹具等。机床夹具的主要作用为:易于保证加工精度,并使一批工件的加工精度稳定;缩短辅助时间,提高劳动生产率,降低生产成本;减轻工人操作强度,降低对工人的技术要求;扩大机床的工艺范围,实现一机多能;减少生产准备时间,缩短新产品试制周期。定位是指确定工件在机床或夹具中占有正确位置的过程。夹紧是指工件定位后将其固定,使工件在加工过程中保持定位位置不变的操作。工件在夹具中的定位通常有以下四种情况:完全定位、部分定位、欠定位、重复定位。工件在夹具中的夹紧是由夹具的夹紧装置完成的。夹紧装置通常由动力装置和夹紧机构两大部分组成。典型的夹紧机构有斜楔夹紧机构、螺旋夹紧机构、圆偏心夹紧机构、定心夹紧机构、铰链夹紧机构、联动夹紧机构等。夹紧动力装置有气动夹紧装置、液压夹紧装置、电磁夹紧装置、真空夹紧装置等。5组合机床设计5.1 组合机床的特点组合机床是由大量的通用部件和少量专用部件组成的工序集中的高效率专用机床。它能够对一种(或几种)零件进行多刀、多轴、多面、多工位加工。在组合机床上可以完成钻孔、扩孔、铣削磨削等工序,生产效率高,加工精度稳定。组合机床与通用机床、其他专用机床比较,具有以下特点:(1) 组合机床上的通用部件和标准零件约占全部机床零、部件总量的7080%,因此设计和制造的周期短,投资少,经济效果好。(2) 由于组合机床采用多刀加工,并且自动化程度高,因此比通用机床生产效率高,产品质量稳定,劳动强度低。(3) 组合机床的通用部件是经过周密设计和长期生产实践考验的,又有厂成批制造,因此结构稳定、工作可靠,使用和维修方便。(4) 在组合机床上加工零件时,由于采用专用夹具、刀具和导向装置等,加工质量靠工艺装备保证,对操作工人水平要求不高。(5)当被加工产品更新时,采用其他类型的专用机床时,其大部分件要报废。用组合机床时,其通用部件和标准零件可以重复利用,不必另行设计和制造。(6)组合机床易于联成组合机床自动线,以适应大规模的生产需要。组合机床常用的通用部件有:机身、底座、立柱、动力箱、动力滑台,各种工艺切削头等。对于一些按循序加工的多工位组合机床,还具有移动工作台或回转工作台。动力箱、各种工艺切削头和动力滑台是组合机床完成切削主运动或进给运动的动力部件。其中还有能同时完成切削主运动和进给运动的动力头。机身、立柱、中间底座等是组合机床的支承部件,起着机床的基础骨架作用。组合机床的刚度和部件之间的精度保持性,主要是由这些部件保证。5.2 组合机床的分类和组成组合机床的通用部件分大型和小型两大类。大型通用部件是指电机功率为1.5-3.0千瓦的动力部件及其配套部件。这类动力部件多为箱体移动的结构形式。小型通用部件是指电机功率为1.1-2.2千瓦的动力部件及其配套部件。这类动力部件多为套筒移动的结构形式。用大型通用部件组成的机床称为大型组合机床。用小型通用部件真诚的机床称为小型组合机床。按设计的要求本次设计的机床为小型通用机床。组合机床除分为大型和小型外,按配置形式又分为单工为和多工位机床两大类。单工位机床又有单面、双面、三面和四面几种,多工位机床则有移动工作台式、回转工作台式、中央立柱式和回转鼓轮式等配置型式。参

本课题是转速器盘钻床夹具的设计与制造,需要研究或解决的问题有如下几个方面:1认真查阅资料,分析转速器盘的结构特点以及相关的技术要求。 2分析通用夹具的结构特点以及相关的技术规范。 3根据转速器盘的特点,设计出适合的钻床夹具结构。 4材料的选择。根据材料的性能不同和经济性,选择适合的夹具材料。同时还要对夹具做受力分析,计算夹紧力,是否满足要求。 5拟订工艺路线。首先划分加工阶段,然后选择表面的加工方法和合适的定位基准,最后确定工序安排的原则。 6确定工序的设计。首先选择机床和工件(刀具和夹具),然后确定加工余量和工序尺寸,最后计算尺寸链。 7编写工艺过程卡片,制定工艺规程。8. 设计关键工序加工的组合机床,包括“三图一卡”二、研究途径(手段) 1通过实习了解转速器盘夹具的机构设计原理。 2通过查阅书籍和资料,设计出几个方案,对偏心轴套铣夹具的优劣进行总结,然后选择最合理的钻床夹具。 3对照毕业设计任务书中的相关技术要求对夹具进行计算,得出合理的设计。 4利用CAD和PRO/E完成偏心轴套铣夹具的零件图和装配图的绘制。 5组合机床的方案选择(1)制定工艺方案 要深入现场了解被加工零件的加工特点、精度和技术要求、定位夹压情况以及生产率的要求等。确定在组合机床上完成的工艺内容及其加工方法。这里要确定加工工步数,决定刀具的种类和型式。(2)机床结构方案的分析和确定 根据工艺方案确定机床的型式和总体布局。在选择机床配置型式时,既要考虑实现工艺方案,保证加工精度,技术要求及生产效率;又要考虑机床操作、维护、修理是否良好;还要注意被加工零件的生产批量,以便使设计的组合机床符合多快好省的要求。(3)组合机床总体方案 这里要确定机床各部件间的相互关系,选择通用部件的刀具的导向,计算切削用量及机床生产率。给制机床的总联系尺寸图及加工示意图等。(4)组合机床的部份方案和施工方案 制定组合机床流水线的方案时,与一般单个的组合机床方案有所不同。 流水线上由于工序的组合不同,机床的型式和数量都会有较大的变化。因此,这时应按流水线进行全面考虑,而不应将某一台或几台机床分裂开来设计。即使暂时不能全面地进行流水线设计,制定方案时也应综合研究,才能将工序组合得更为合理,更可靠地满足工件的加工要求,用较多的工作,也为进一步发展创造了有利条件。以上只是对本次毕业设计的一些初步思考,在毕业设计过程中将不断纠正设计方向,完善设计理念。 毕 业 设 计(论

日附件1:外文资料翻译译文机电一体化技术一、机电一体化技术发展历程及其趋势自电子技术一问世,电子技术与机械技术的结合就开始了,只是出现了半导体集成电路,尤其是出现了以微处理器为代表的大规模集成电路以后,机电一体化技术之后有了明显进展,引起了人们的广泛注意。(一)机电一体化的发展历程1.数控机床的问世,写下了机电一体化历史的第一页;2.微电子技术为机电一体化带来勃勃生机; 3.可编程序控制器、电力电子等的发展为机电一体化提供了坚强基础;4.激光技术、模糊技术、信息技术等新技术使机电一体化跃上新台阶。(二)机电一体化发展趋势 1.光机电一体化。一般的机电一体化系统是由传感系统、能源系统、信息处理系统、机械结构等部件组成的。因此,引进光学技术,实现光学技术的先天优点是能有效地改进机电一体化系统的传感系统、能源(动力)系统和信息处理系统。光机电一体化是机电产品发展的重要趋势。2.自律分配系统化柔性化。未来的机电一体化产品,控制和执行系统有足够的冗余度,有较强的柔性,能较好地应付突发事件,被设计成自律分配系统。在自律分配系统中,各个子系统是相互独立工作的,子系统为总系统服务,同时具有本身的自律性,可根据不同的环境条件作出不同反应。其特点是子系统可产生本身的信息并附加所给信息,在总的前提下,具体行动是可以改变的。这样,既明显地增加了系统的适应能力(柔性),又不因某一子系统的故障而影响整个系统。3.全息系统化智能化。今后的机电一体化产品全息特征越来越明显,智能化水平越来越高。这主要收益于模糊技术、信息技术(尤其是软件及芯片技术)的发展。除此之外,其系统的层次结构,也变简单的从上到下的形势而为复杂的、有较多冗余度的双向联系。4.生物一软件化仿生物系统化。今后的机电一体化装置对信息的依赖性很大,并且往往在结构上是处于静态时不稳定,但在动态(工作)时却是稳定的。这有点类似于活的生物:当控制系统(大脑)停止工作时,生物便死亡,而当控制系统(大脑)工作时,生物就很有活力。仿生学研究领域中已发现的一些生物体优良的机构可为机电一体化产品提供新型机体,但如何使这些新型机体具有活的生命还有待于深入研究。这一研究领域称为生物软件或生物系统,而生物的特点是硬件(肌体)软件(大脑)一体,不可分割。看来,机电一体化产品虽然有向生物系统化发展趋,但有一段漫长的道路要走。5.微型机电化微型化。目前,利用半导体器件制造过程中的蚀刻技术,在实验室中已制造出亚微米级的机械元件。当将这一成果用于实际产品时,就没有必要区分机械部分和控制器了。届时机械和电子完全可以融合,机体、执行机构、传感器、CPU等可集成在一起,体积很小,并组成一种自律元件。这种微型机械学是机电一体化的重要发展方向。二、典型的机电一体化产品机电一体化产品分系统(整机)和基础元、部件两大类。典型的机电一体化系统有:数控机床、机器人、汽车电子化产品、智能化仪器仪表、电子排版印刷系统、CADCAM系统等。典型的机电一体化元、部件有:电力电子器件及装置、可编程序控制器、模糊控制器、微型电机、传感器、专用集成电路、伺服机构等。这些典型的机电一体化产品的技术现状、发展趋势、市场前景分析从略。三、我国发展机电一体化面临的形势和任务机电一体化工作主要包括两个层次:一是用微电子技术改造传统产业,其目的是节能、节材,提高工效,提高产品质量,把传统工业的技术进步提高一步;二是开发自动化、数字化、智能化机电产品,促进产品的更新换代。 (一)我国机电一体化工作面临的形势1. 我国用微电子技术改造传统工业的工作量大而广,有难度。2. 我国用机电一体化技术加速产品更新换代,提高市场占有率的呼声高,有压力。3. 我国用机电一体化产品取代技术含量和附加值低,耗能、耗水、耗材高、污染、扰民产品的责任重,有意义。在我国工业系统中,能耗、耗水大户,对环境污染严重的企业还占相当大的比重。近年来我国的工业结构、产品结构虽然几经调整,但由于多种原因,成效一直不够明显。这里面固然有上级领导部门的政出多门问题,有企业的故土难离,死守故业问题,但不可否认也有优化不出理想的产业,优选不出中意的产品问题。上佳的答案早就摆在了这些企业的面前,这就是发展机电一体化,开发和生产有关的机电一体化产品。机电一体化产品功能强、性能好、质量高、成本低,且具有柔性,可根据市场需要和用户反映时产品结构和生产过程做必要的调整、改革,而无须改换设备。这是解决机电产品多品种、少批量生产的重要出路。同时,可为传统的机械工业注入新鲜血液,带来新的活力,把机械生产从繁重的体力劳动中解脱出来,实现文明生产。另外,从市场需求的角度看,由于我国研制、开发机电一体化产品的历史不长,差距较大,许多产品的品种、数量、档次、质量都不能满足需求,每年进口量都比较大,因此亟需发展。(二) 我国机电一体化工作的任务我国在机电一体化方面的任务可以概括为两句话:一句话是广泛深入地用机电一体化技术改造传统产业;另一句话是大张旗鼓地开发机电一体化产品,促进机电产品的更新换代。总的目的是促进机电一体产业的形成、为我国产业结构和产品结构调整作贡献。总之,机电一体化技术既是振兴传统机电工业的新鲜血液和源动力,又是开启我国机电行业产品结构、产业结构调整大门的钥匙。四、我国发展机电一体化的对策(一)加强统筹安排,协调发展计划目前,我国从事机电一体化研究开发及生产的单位很多。各自都有一套自己的发展策略。各单位的计划由于受各自立足点、着眼点的限制,难免只考虑局部利益,各主管部门的有关计划和规划,也有统一考虑不足,统筹安排不够的问题,同时缺少综观全局的有权威性的发展计划和战略规划。因此,建议各主管部门责成有关单位在进行深入调查研究、科学分析的基础上,制定出统管全局的机电一体化研究、开发、生产计划和规划,避免开发上重复,生产上撞车。(二)强化行业管理,发挥协会作用目前,我国机电一体化较热,而按目前的行业划分方法和管理体制,政出多门是难哆的。因此,我国有必要明确一个机电一体化行业的统管机构,根据目前国家政治体制改革和经济体制改革的精神,以及机电一体化行业特点,我们建议,尽快加强北京机电一体化协会的建设,赋予其行业管理职能。协会要进一步扩大领导机构理事会的代表层面和复盖面,要加强办公室、秘书处的建设;要通过其精明干练的办事机构、经济实体,组织行业发展计划、战略规划的拟制;指导行业布点布局的调整,进行发展突破口的选择,抓好重点工程的试点和有关项目的发标、招标工作(三)优化发展环境、增大支持力度优化发展环境指通过宣传群众,造成一种社会上下、企业内外都重视、支持机电一体化发展的氛围,如尽快为外商到我国投资发展机电一体化产业提供方便;尽可能为兴办开发、生产机电一体化产品的高新技术企业开绿灯;尽力为开发、生产机电一体化产品调配好资源要素等。增大支持力度,在技术政策上,要严格限制耗电、耗水、耗材高的传统产品的发展,对未采用机电一体化技术落后产品限制强制淘汰;大力提倡用机电一体化技术对传统产业进行改造,对有关机电一体化技术对传统产业乾地改造,对有关技术开发、应用项目优先立项、优先支持,对在技术开发、应用中做出贡献的单位领导、科技人员进行表彰奖励等。 (四)突出发展重点,兼顾两个层次机电一体化产业复盖面非常广,而我们的财力、人力和物力是有限的,因此我们在抓机电一体化产业发展时不能面面俱到、平铺直叙,而应分清主次,大胆取舍,有所为,有所不为。要注意抓两个层次上的工作。第一个层次是面上的工作,即用电子信息技术对传统产业进行改造,在传统的机电设备上植入或嫁接上微电子(计算机)装置,使机械和电子技术在浅层次上结合。第二个层次是提高工作,即在新产品设计之初,就把机械与电子统一起来进行考虑,使机械与电子密不可分,深度结合,生产出来的新产品起码正做到机电一体化。结束语:本论文在各位老师的悉心指导和严格要求下已完成。在学习和生活期间,也始终感受着导师的精心指导和无私的关怀,我受益匪浅。在此向各位老师表示深深的感谢和崇高的敬意。不积跬步何以至千里,本设计能够顺利的完成,也归功于各位任课老师的认真负责,使我能够很好的掌握和运用专业知识,并在设计中得以体现。同时我在网上也搜集了不少资料,才使我的毕业论文工作顺利完成。在此向学院工程系的全体老师表示由衷的谢意。附件2:外文原文Electromechanical Integration1. electromechanical integration and the development of technology trends Since an electronic technology birth of electronic technology and mechanical technology integration began, only a semiconductor integrated circuit, particularly in a microprocessor representative of the large-scale integrated circuits for the future, “mechatronics,” a technical after significant progress, and has attracted widespread attention. (1) mechanical-electrical integration, “the course of development 1. CNC machine tools come out, wrote “mechatronics,” the first page of history; 2. Microelectronic technology, “mechatronicsbring a great vitality; 3. PLC, “Power Electronics” for the development of “mechatronics” provide a firm foundation; 4. Laser technology, fuzzy technology, information technology and other new technologies to “mechanical and electrical integration,” a new and higher level. (B) mechanical-electrical integration, “the development trend 1. Integration of optical and electrical machinery. General mechanical and electrical integration system by sensing systems, energy systems, information processing systems, machinery, and other components of the structure. Therefore, the introduction of optical technology, the realization of the inherent advantages of optical technology is effective Improved mechanical-electrical integration system sensing system, energy (power) systems and information processing system. optical and electrical machinery integration is the development of mechanical and electrical products trend. 2. Systematic self-distribution - Flexible Future electromechanical integration products, and implementation of control systems are adequate “redundancy” and more “flexible” and can better deal with an emergency, is designed “self-distribution system.” Self-discipline in the distribution system, the various subsystems are independent of each others work, the subsystem for system services, and has its own “self-discipline”, according to different environmental conditions react differently. Its characteristics are subsystem can generate its own information and additional information given in the overall premise, specific “action” can be changed. In this way, significantly increase the systems ability to adapt (flexible), not because of the failure of a subsystem of the whole system. 3. Holographic systematic - intelligent. Future integration of mechanical and electrical products, “holographic” features more and more obvious, more and more high-level intelligence. This is mainly revenues in the fuzzy technology, information technology (especially software and chip technology) development. In addition, the hierarchical structure of the system, a simple change of “top-down” situation is complex, there is much more two-way link redundancy. 4. “Of a software” of the - Biomimetic systematic. Future integration of electrical and mechanical devices on the dependence of great information, and often the structure is in a “static” instability, but in a dynamic (work) when is stable. This is a bit like living biological: When control system (the brain) to stop work, then of “Death”, and when control system (brain) work, the biological vitality. Bionics research in the field of a number of organisms have been found good institutions can provide products for the electrical and mechanical integration of the new body, but how to live with these new body of “Life” has to be in-depth study. This field of study referred to as “biological - Software” or “biological - System”, and biological characteristics of the hardware (body) - Software (brain) one and indivisible. It seems, electromechanical integration of the products although there are more systematic development, but there is a long way to go. 5. MEMS of - miniaturization. At present, the semiconductor devices used in the manufacturing process of etching technology, in the lab has produced sub-micron mechanical components. When will this result for the actual product, there is no need to distinguish between the mechanical part and controller. Will be completely mechanical and electronic “integration”, and the body, the Executive Body, sensors, such as CPU can be integrated with the size of a small, and the formation of a self-regulatory components. This micro-mechanical integration of electromechanical important direction of development. Second, the typical electromechanical integration products Mechanical and electrical subsystems integration products (complete machine) and the foundation yuan, part two categories. Typical mechanical-electrical integration system: CNC machine tools, robotics, automotive electronic products, intelligent instrumentation, electronic publishing printing systems, CAD / CAM systems. Typical electromechanical integration yuan, components are: power electronic devices and devices, programmable logic controller, fuzzy controller, micro-motors, sensors, ASIC, servo institutions. These typical electromechanical integration of technical status quo and development trends, market analysis of (not quoted). Third, Chinas development “mechatronics” the situation and tasks facing Mechanical and electrical integration mainly include two levels: First, by using microelectronic technology to transform traditional industries, and its purpose is energy and materials to enhance efficiency, improve product quality, the traditional industries of technological advances in improving step two is to develop automated, digital , intelligent mechanical and electrical products, and promote the upgrading of products. (1) Chinas “mechatronics” of the situation facing 1. Chinas microelectronics technology to transform traditional industries with the workload of large and broad, difficult 2. Electromechanical integration technology with Chinas accelerated product upgrading, enhancing the voice of the market share, pressure. 3. Electromechanical integration with China replaced by products of low technology content and added value, energy, water, supplies, pollution, disturbing product liability heavy and meaningful. Chinas industrial systems, energy consumption, water consumption big, serious environmental pollution enterprises also accounted for a fairly large proportion. In recent years Chinas industrial structure, product mix Although several adjustments, but for various reasons, lack of effectiveness has been obvious. This is a higher level inside leading departments from many doors, enterprises are “finding it hard to leave their native land”, “is entrenched industry”, but also optimize the undeniable not the ideal industry, the optimized no Italian products. The best answer long ago put these enterprises in the face, this is the development of mechanical and electrical integration, development and production of the electrical and mechanical integration products. Mechatronics product features strong, good performance, high-quality, low cost, and has a flexible, according to the needs of the market and reflect the user when the product mix and production process to do the necessary restructuring and reform, instead of switching equipment. This is the solution of mechanical and electrical products and more variety, the less important way to mass production. At the same time, for the traditional mechanical industries injection of fresh blood, bringing new vitality, and the heavy machinery production from the manual relieved to achieve civilized production. Furthermore, from the point of view of market demand, Chinas research and development of mechanical and electrical integration products with no long history, a big gap between the many varieties of product, quantity, grade, quality, can not meet the demand, larger than the annual import volume, much-needed development. (2) Chinas “mechatronics,” the task Chinas mechanical and electrical integration, the task can be summed up in two sentences: The first observation is extensively used electromechanical integration technology to transform traditional industries; Another observation is that the mechanical and electrical integration in a big way to develop products, and promote the upgrading of mechanical and electrical products. The overall goal is to promote the formation of mechanical and electrical integration industry for Chinas industrial structure and product mix adjustment and make contributions. In short, electromechanical integration technology is to revitalize traditional electromechanical industrial source of fresh blood and driving force, is to open Chinas electromechanical industry products, the industrial structure adjustment of the keys to the door. Fourth, Chinas development “mechatronics” Countermeasures (1) strengthen the co-ordination arrangements, coordinated development plan Currently, the country engaged in “mechatronics” research and development and production of many units. Each had a set of its own development strategy. The units in their plans because of the foothold, the focus of the restrictions, it is inevitable to consider only local interests, the competent departments of the project and planning, lack of a unified consider, and make enough issue, the lack of authoritative Looking at the overall development plans and strategic planning. It is therefore recommended that the competent departments instruct the relevant units of in-depth investigation and study and scientific analysis on the basis of the overall development of a unified management “mechatronics” research, development, production plans and programmes to avoid duplication of development, production crashes! (B) strengthen regulation of the industry, to play the “Association” role At present, Chinas “mechatronics” more heat, while the current industry breakdown methods and management system, “from many doors” is the difficult pyridoxine. Therefore, it is necessary to clarify our country a “mechatronics” industrys management body, according to the countrys political and economic reforms the spirit, as well as mechanical and electrical integration industry characteristics, we propose that the Beijing as soon as possible to strengthen the construction of the Electrical and Mechanical Integration Association, given its industry management functions. “Association” We should further expand the leadership - the representatives of the Governing Council and the level of coverage, we must strengthen the Office of the Secretariat building; able to pass its smart offices, economic entities, organizations, “industry” development, strategic planning fiction; guidance layout layout of the industry adjustment, the starting point for the development of options, do a good job of the pilot and key projects of the issuing of the project, the tender exercise (C) Optimization development environment, increased support for the Optimization development environment that through propaganda among the masses, creating a community as a whole, both inside and outside the enterprise to support “the mechanical and electrical integration,” the atmosphere of development, such as China as soon as possible for foreign investors to invest in the development of “mechatronics” industry to provide convenient as possible for the establishment of development, production integration of mechanical and electrical products give the green light to high-tech enterprises; endeavour to develop, manufacture electromechanical integration products, such as the deployment of elements of good resources. Increase the intensity of support, technology policy, it is necessary to strictly limit the consumption of electricity, water, supplies high-traditional product development, did not use the mechanical and electrical integration of backward technology products restrictions mandatory elimination; strongly advocated using electromechanical integration on the traditional industries for the transformation of the electrical and mechanical integration technology to transform traditional industries dry on the technical development and application of project priority projects, and give priority support to the technical development and application of the unit to contribute to leadership, science and technology personnel of recognition incentives. (D) to highlight key development, take into account the “two levels” Mechatronics industries cover a very wide, and our financial, human and material resources are limited, so we grasp mechatronics industry development can not be exhaustive, Bengpuzhixu, it should distinguish between primary and secondary, bold choices, in order, selective. Attention should be paid to work on two levels. The first level is the “face” of work, namely the use of electronic information technology to transform traditional industries, in the traditional electromechanical devices implanted or grafted on Microelectronics (computer) devices, the “machinery” and “electronic” technology in the Jiancengci integrate. The second level is the “increase”, that is the beginning of the new product design, they “machinery” and “electronic” unified consideration, “machinery” and “electronic” inextricably linked, in-depth integration of the new production Products are at least do electromechanical integration. CONCLUSION: In this paper, in the careful guidance of teachers and strict requirements have been completed. Learning and life, will always feel the careful guidance of a mentor and selfless caring, I benefited. You are here to express our deep gratitude and lofty respect. Why not plot to step of a thousand miles, the smooth completion of the design, but also owe much to the datum related to the serious and responsible teacher, I can well understand and use our professional knowledge, and to be reflected in the design. At the same time, I collected a lot of online information before making my dissertation work smoothly. College of Engineering here to all teachers expressed heartfelt thanks.
