精密机械设计基础第二章工程材料和热处理
化学热处理工艺较多,如渗碳、氮化、碳氮 共渗等,渗人的元素不同,会使工件表面 所具有性能也不同。
(1)渗碳 渗碳是向钢件表面层渗入碳原子的过程。
(2)氮化 氮化是向钢件表面层渗入氮原子的过程。
(3)碳氮共渗(氰化) 碳氮共渗是向钢的表层同时渗人碳和氮的 过程,习惯上又称为氰化 。

三、延展性
1.伸长率δ: 试件拉断后,标距内的伸长量与 标距原长之比的百分率称为伸长率
δ>5%者为塑性材料 δ<5%者为脆性材料 2.断面收缩率ψ:试件拉断后,断裂处面积的 缩小量与原面积之比的百分率称为断面收缩率。
• 标距l:在试件等直部分取长为l的工作段 • 伸长率或断面收缩率愈大,材料的塑性愈高

3、韧性能:材料在断裂前所能吸收的能量
若应力超过比例极限,材料就要产生永久变 形,应变能的大部分将消耗在材料的塑性变形上, 并以热的形式散失

2、零件的特性误差估算 1)绝对误差估算 例如片簧的弹性变形
4 EFb33Lh f(L,b,h,E)
片簧变形的绝对误差为
dfd Lfd bfd hfdE
L b h E
写成增量形式,略去高阶无穷小,
fL fb fh fE
3、精度要求 精度是精密机械的一项重要技术指标,设 计时必须保证精密机械正常工作时所要求的精度。
4、经济性要求 组成精密机械的零部件能被最经济的制 造出来,这就要求零件结构简单、节省材料、工艺性 好,尽量采用标准尺寸和标准件。
5、外观要求 设计精密机械时应使其造型美观大方,色 泽柔和。
“活到老,学到老”,人需要不断的学习和思考,这样才会 进步!通过学习著名企业的一些宝贵资料和经典案例,不仅 能提升您的个人素质,同时也能为您以后的工作带来极大的 帮助,一个人的核心竞争力,源自于其学习力!为知识付费 是您最值得的投资!
三、精度 是表征测得结果与真实值的接近程度的量。精度的
高低是用误差的大小来度量的,误差越小,则精度越高。
四、误差的来源:
1、设计误差(原理误差)(产生于设计过程) 由于采用近似机构代替理想机构,或采用了近似
假设,使得设计的零件或机构在原理上产生了误差。
2、工艺误差 (产生于制造过程) 由于零件的加工和装配过程中,由机床、刀具、
二、是机指构实误际差机:构运來动自3精72度2 中与国理最想大机的构资运料库动下精载度之间的 偏差,常用机构位置误差和位移误差表示。 1、机构的位置误差: 当实际机构与理想机构的主动件 位置相同时,两者从动件位置的偏差。(B0B0’) 2、机构的位移误差: 实际机构与理想机构的主动件位 移相同时,两者从动件位移量的偏差。(B1B0 - B1’B0’)

机械设计基础(英汉互译)
Fundamentals of Mechanical DesignMechanical design means the design of things and systems of things and systems of a mechanical nature-machines, products, structures, devices, and instruments. For the most part mechanical design utilizes mathematics, the materials sciences, and the engineering-mechanics sciences.The total design process is of interest to us. How does it begin? Does the engineer simply sit down at his desk with a blank sheet of paper? And, as he jots down some ideas, what happens next? What factors influence or control the decisions which have to be made? Finally, then, how does this design process end?Sometimes, but not always, design begins when an engineer recognizes a need and decides to do something about it. Recognition of the need phrasing it in so many words often constitute a highly creative act because the need may be only a vague discontent, a feeling of uneasiness, or a sensing that something is not right.The need is usually not evident at all. For example, the need to do something about a food-packaging machine may be indicated by the noise level, by the variation in package weight, and by slight but perceptible variations in the quality of the packaging or wrap.There is a distinct difference between the statement of the statement of the need and the identification of the problem which follows this statement. The problem is more specific. If the need is for cleaner air, the problem might be that of reducing the dust discharge from power-plant stacks, or reducing the quantity of irritants from automotive exhausts.Definition of the problem must include all the specifications for the thing that is to be designed. The specifications are the input and output quantities, the characteristics and dimensions of the space the thing must occupy and all the limitations on these quantities. We can regard the thing to be designed as something in a black box. In this case we must specify the inputs and outputs of the box together with their characteristics and limitations. The specifications define the cost, the number to be manufactured, the expected life, the range, the operating temperature, and the reliability.There are many implied specifications which result either from the designer’s particular environment or from the problem itself. The manufacturing processes which are available, together with the facilities of a certain plant, constitute restrictions on a designer’s freedom, and hence are a part of the implied specifications. A small plant, for instance, may not own cold-working machinery. Knowing this, the designer selects other metal-processing methods which can be performed in the plant. The labor skills available and the competitive situation also constitute implied specifications.After the problem has been defined and a set of written and implied specifications has been obtained, the next step in design is the synthesis of an optimum solution. Now synthesis cannot take place without both analysis and optimization because the system under design must be analysis and optimization because the system under design must be analyzed to determine whether the performance complies with the specifications.The design is an iterative process in which we proceed through several steps, evaluate the results, and then return to an earlier phase of the procedure. Thus we may synthesize several components of a system, analyze and optimize them, and return to syntheses to see what effect this has on the remaining parts of the system. Both analysis and optimization require that we construct or devise abstract models of the system which will admit some form of mathematical analysis. Wecall these models mathematical models. In creating them it is our hope that we can find one which will simulate the real physical system very well.Evaluation is a significant phase of the total design process. Evaluation is the final proof of a successful design, which usually involves the testing of a prototype in the laboratory. Here we wish to discover if the design really satisfies the need or needs. Is it reliable? will it compete successfully with similar products? Is it economical to manufacture and to use? Is it easily maintained and adjusted? Can a profit be made from its sale or use?Communicating the design to others is the final, vital step in the design process. Undoubtedly many great designs, inventions, and creative works have been lost to mankind simply because the originators were unable or unwilling to explain their accomplishments to others. Presentation is a selling job. The engineer, when presenting a new solution to administrative, management, or supervisory persons, is attempting to them that this solution is a better one. Unless this can be done successfully, the time and effort spent on obtaining the solution have been largely wasted.Basically, there are only three means of communication available to us. These are the written, the oral. And the graphical forms. Therefore the successful engineer will be technically competent and versatile in all three forms of communication. A technically competent person who lacks ability in any one of these forms is severely handicapped. If ability in all three forms is locking, no one will ever know how competent that person is!The competent engineer should not be afraid of the possibility of not succeeding in a presentation. In fact, occasional failure should be expected because failure or criticism seems to accompany every really creative idea. There is a great deal to be learned form a failure, and the greatest gains are obtained by those willing to risk defeat. In the final analysis, the real failure would lie in deciding not to make the presentation at all.机械设计基础机械设计是指机械装置和机械系统——机器、产品、结构、设备和仪器的设计。

精密机械加工工艺
在机械加工过程中,工件受到切削力、离心力、惯性力等的作用,为了保证在 这些外力作用下,工件仍能在夹具中保持已由定位元件确定的加工位置,而不致 发生振动或位移、夹具结构中应设置夹紧装置将工件可靠夹牢。 一、夹紧装置的组成 夹紧装置的种类很多,但其结构均由两部分组成。 1.动力装置 夹紧力的来源,一是人力;二是某种装置所产生的力。能产生力的装置称为夹 具的动力装置。常用的动力装置有:气动装置、液压装置、电动装置、电磁装置、 气—液联动装置和真空装置等。由于手动夹具的夹紧力来自人力,所以它没有动 力装置。 2.夹紧部分 接受和传递原始作用力使之变为夹紧力并执行夹紧任务的部分,一般由下列机 构组成: 1)接受原始作用力的机构。如手柄、螺母及用来连接气缸活塞杆的机构等。 2)中间递力机构。如铰链、杠杆等。 3)夹紧元件。如各种螺钉压板等。 其中中间递力机构在传递原始作用力至夹紧元件的过程中可以起到诸如改变 作用力的方向、改变作用力的大小以及自锁等作用。 二、夹紧装置的基本要求 在不破坏工件定位精度,并保证加工质量的前提下,应尽量使夹紧装置做到: 1. 夹紧力的大小适当。既要保证工件在整个加工过程中其位置稳定不变、振动小, 又要使工件不产生过大的夹紧变形。 2.工艺性好。夹紧装置的复杂程度应与生产纲领相适应,在保证生产效率的 前提下,其结构应力求简单,便于制造和维修。 3.使用性好。夹紧装置的操作应当方便、安全、省力。 三、基本夹紧机构 原始作用力转化为夹紧力是通过夹紧机构来实现的。在众多的夹紧机构中以斜 楔、螺旋、偏心以及由它们组合而成的夹紧机构应用最为普遍。 (一)斜楔夹紧机构 采用斜楔作为传力元件或夹紧元件的夹紧机构称为斜楔 夹紧机构。 直接采用斜楔夹紧时,斜楔的自锁条件是:斜楔的升角小于斜楔与工 件、斜 楔与夹具体之间的摩擦角之和。

精密机械设计基础1 2章习题答案精密机械设计基础1-2章习题答案答案:第一章1-1求解:力和力偶无法制备;力偶也不可以用力去均衡。
1-2解:平面汇交力系可以列出两个方程,解出两个未知数。
1-3解:q(x)取坐标系如图,如图知q(x)?100x则载荷q(x)对a点的矩为1-4求解:1)ab杆就是二力杆,其受力方向例如图,且fa’=fb’2)oa杆在a点受力fa,和fa’是一对作用力和反作用力。
似乎oa杆在o点受力fo,fo和fa形成一力偶与m1均衡,所以存有fa?oa?sin30??m1?0代入oa=400mm,m1=1n?m,得fa=5n所以fa’=fa=5n,fb’=fa’=5n,即为杆ab难以承受的力s=fa’=5n3)同理,o1b杆在b点受力fb,和fb’就是一对作用力和反作用力,fb=fb’=5n;且在o1点受力fo1,fo1和fb形成一力偶与m2均衡,所以存有m2?fb?o1b?0代入o1b=600mm,得m2=3n.m。
1-5解:n2fb’bfbm2ofo1o11)首先取球为受力分析对象,受到重力p,墙壁对球的也已压力n2和杆ab对球的也已压力n1,处在均衡。
存有:fam1fofa’axma(q)??q(x)?(2?x)dx?66.7(kn?m)01tbn1?sin??p则n1?p/si?nn1d2)取杆ab进行受力分析,受力如图所示,d杆ab平衡,则对a点的合力矩为0:afay?faxn1’ma(f)?t?l?cos??n1?ad?03)根据几何关系存有ad?aaa(1?cos?)??sin?tan?sin?pa1?1/cos?pa1lsin2?lcos??cos2?pa2当cos??cos?最小,即为?=60°时,存有tmin=。
4l最后解得:t?11-6解:1)取整体结构为行受力分析,在外力(重力p、在b点的也已压力fb和在c点的也已压力fc)促进作用下均衡,则对bN55XI243SF矩,再分力矩为0:mb(f)?0?fc?2l?cos??p(2lcos??acos?)解得fc?p(1?fcfbafaaa),fb?p?fc?p2l2l2)ab杆为三力杆,三力呈报,存有受力例如图所示。
