LETTER 1 Dear Ann, I am going to give a dinner party next month. I want my guests to enjoy themselves and to feel comfortable. What is the secret of giving a successful party? Sarah LETTER 2 Dear Mary, Cook something that would let you spend time with your guests. If a guest offers to help you in the kitchen, accept the offer. It often makes people feel more comfortable when they can help. Before serving dinner, while your guests make small talks in the living room, offer them drinks. Some guests may like wine, but make sure to provide soft drinks for people who don’t. At the dinner table, let your guests serve themselves. Offer them a second serving after they finish, but don’t ask more than once. Most guests will take more if they want. Perhaps the most important rule of all is to be natural. Treat your guests as you want them to treat you when you’re in their home—that is, act naturally toward them, and don’t try too hard to be polite. Have a good time in a pleasant atmosphere. Yours, Vida 1、From the first letter we learn that Mary is asking for advice on giving a dinner party. 2、Ann's first piece of advice is that Mary should accept the guests’offer to help. 3、Ann suggests that Mary offer drinks while the guests are having small talks B) when all the guests have arrived. 4、When having dinner, the guests are expected to help themselves to more food.

课程设计(论文) C6140车床对开合螺母座工艺规程与工装 设计 学号: 姓名:高金宝 专业:机械工程 系别:机械与电气工程系 指导教师:朱庆芹 二○一五年十二月 目录

1零件的分析 零件的分析 根据零件的生产钢领为500件/年,零件为中批量生产。性能要求:上下螺母动作同步,螺母与丝杠的同轴度。 制定工艺路线的出发点是使零件的几何形状,尺寸精度及位置精度等技术要求能得到保证。在生产纲领确定的条件下,可以考虑采用万能的专用夹具等,并尽量使工序集中来提高生产率,考虑经济效果,减少成本。

确定铸造方案 铸造方法为沙型铸造,可选用湿型,铸造材料选择粘土沙,灰铸铁的尺寸公差等级为13-15级,选14级 毛坯的浇注方式为两箱侧面浇注 毛坯的确定 根据零件图所给的尺寸和要求,可知零件毛坯材料为HT200 确定毛坯的基本尺寸 毛坯余量是在零件图基础上放大的,根据零件图上的尺寸确定如下基本尺寸:包括105、、33、18、φ52H7的孔(孔的精度等级比铸造的精度等级低一级) 确定铸件的尺寸偏差 由资料查得2级铸铁尺寸偏差为上下各 零件的作用 零件的功能:用于接通和断开从丝杠传来的运动,车削螺纹时,将开合螺母合上,丝杠通过对开合螺母体脱开。车削螺母时,顺时针方向转动手柄,通过轴带动曲线槽盘转动,曲线槽盘上的曲线槽盘上的曲线槽盘形状,通过圆柱销带动上半螺母在溜板箱体后面的燕尾形导轨内上下移动,

使其相互靠拢,将对开螺母体和丝杠啮合。若逆时针方向转动手柄,则两半螺母相互分离,对开螺母体和丝杠脱开。槽盘的曲线槽是一段圆弧,此圆弧在接近槽盘中心部分的倾角比较小目的是对开螺母体闭合能自锁,不会自动脱开。 2工艺规程设计 加工原则 先粗后精,加工分阶段进行,基准先行,先主后次,先面后孔 基面的选择 粗基准的选择:由先粗后精的原则,选取燕尾为粗基准,利用左右两个定位块和一个削边对其进行限制,达到过定位。对于精基准,主要是基准重合。 工序的确定 初步设定工艺路线(先粗后精,先面后孔) 铸造-预先热处理-粗刨(铣)C面B面D面-铣(1-3退刀槽)-粗加工两E面-粗镗(φ52)孔-半精刨(C面,E面)-精刨(C面,E面)-刮研(C,E面)-精加工两E面-半精镗(φ52)-精镗(φ52H7孔)-钻,铰(φ12H7孔)-铣切(5mm)分离上下螺母座-钻M10底孔(φ)-攻M10螺纹-钻(2—φ7)清理毛刺-检验

2018年人文英语1期末复习资料

第二部分样题一 一、交际用语(共计10 分,每小题2 分) 1~5 题:选择正确的语句完成下面的对话。 1.— Hi, Wang Xin, nice to meet you! — Hi, Liu Hui. A. Nice to meet you too. B. How do you do ? C. I'm fine, thank you. 答案: A 解析:本题考查“互相问候”的交际用语。第一说话人以nice to meet you (见到你很高兴)问候对方时,答语 应用 nice to meet you too 来回应,所以答案是A。 2.— How about going to the class together ? — A. Of course not. B. That sounds great. C. I don't like it. 答案: B 解析:本题考查“提出建议”的交际用语。第一说话人提出一起去上课的建议,如果赞同,根据给出答案,答 语应该是这听起来不错;如果不赞同,则应委婉礼貌地拒绝, C 答案语气太强硬,不太礼貌,所以答案是B。3.— Thank you for sharing this with me. — A. Nothing. B. You can share, too. C. My pleasure! 答案: C 解析:本题考查“回复致谢”的交际用语。My pleasure 是 It's my pleasure 的缩写,意为“不客气、很荣幸”。 常见的表达“不客气”的短语还有:You are welcome/don't mention it/Sure thing 等,所以答案是C。 4.— What will you buy for the Spring Festival ? — A. I will buy gifts for my family. B. Clothes are on sale. C. I want to go shopping. 答案: A 解析:本题考查“购物”的交际用语。“新年到了,你想买点儿什么呢”,应作出针对性的回答,即为 A 项:“我 想买些礼物送给家人” ;其余两项回答不够清晰,所以答案是A。 5.— — It's dark brown. A. How about his weight ? B. Is he a tall guy? C. What color is his hair ? 答案: C 解析:本题考查“表示询问”的交际用语。第二说话人回答的“dark brown 深褐色”是颜色,因此推断出第一说话人应该是询问跟颜色有关的问题,所以答案是C。 二、词汇与结构(共计30 分,每小题2 分)

三孔连杆加工工艺及夹具设计

3.1 三孔连杆零件图介绍 三孔连杆的零件图如图1所示。经检查之后,视图足够并正确,所需要的尺寸、公差、表面粗糙度、和技术要求全部齐全、合理,而且零件的表面质量、表面精度和技术要求在现有的技术条件和生产条件下能够达到。 图3-1 三孔连杆零件图 3.2 零件的工艺分析 参考机械制造工艺设计中的零件的工艺分析方法,对三孔连杆的工艺进行分析 (1)铣平面后,立即确定大头孔平面为以下各序加工的主基准面,这样可确保 加工质量的稳定。

(2)铣平面时,应保证小头孔及耳部孔平面厚度与大头孔平面厚度的对称性。 (3)由于连杆三个孔平面厚度不一致,因此,加工中要注意合理布置辅助支承及应用。 (4)连杆平面加工也可以分为粗、精两序,这样可更好的保证三个平面相互位置及尺寸精度。 (5)粗、精镗三孔也可改用专用工装或组合夹具装夹。 (6)当加工连杆尺寸较小时,粗、精加工三孔也可采用镗削加工方法。三孔的精度要求较高,可以分为粗、精两工序。 (7)连杆三孔平行度的检验;连杆三孔圆柱度的检验。 3.3 毛坯的选择 连杆是发动机的五大主关件之一,其在发动机中的地位是显而易见。它是发动机传递动力的主要运动件,在机体中做复杂的平面运动,连杆小头随活塞作上下往复运动连杆大头随曲轴作高速回转运动连杆杆身在大、小头孔运动的合成下作复杂的摆动[3]。连杆在承受往复的惯性力之外,还要承受高压气体的压力,在气体的压力和惯性力合成下形成交变载荷,这就要求连杆具有耐疲劳、抗冲击,并具备足够的强度、刚度和较好的韧性。在今天随着汽车工业的高速发展,“ 小体积、大功率、低油耗”的高性能发动机对连杆提出更新、更高的要求作为高速运动件重量要轻,减小惯性力,降低能耗和噪声强度、刚度要高,并具有较高的韧性连杆比要大,连杆要短。这也就意味着对连杆的设计和加工有更高的要求。 3.3.1 选择毛坯时应考虑的因素 在选择毛坯的时候应考虑以下因素[4]: (1)毛坯的种类和特点,设计图纸规定的材料和机械性能;零件结构形状和外形尺寸;不同的毛坯的制造方法对结构和尺寸有特定的要求;企业现有的生产条件;新工艺,新材料新技术的应用。 (2)毛坯结构形状和尺寸,毛坯形状应力求接近零件形状,以减少机械加工劳动量。毛坯尺寸是在原有零件尺寸基础上,考虑后续加工切除余量确定。毛坯形状也有几种特殊情况。如尺寸小而薄的零件,多个工件连在一起由一个毛坯制造出;某些零件如车床开合螺母外壳,两件合为一个毛坯,加工至一个阶段后再切开;为加工时安装方便,毛坯上留有工艺搭子。 (3)毛坯制造精度,毛坯制造精度高,材料利用率高,后续加工费用低,但相应设备投入大。因此,确定毛坯制造精度时,需要综合考虑毛坯制造成本和后续加工成本。
