绪论机械制造业是制造具有一定形状位置和尺寸的零件和产品,并把它们装备成机械装备的行业。
机械制造业的产品既可以直接供人们使用,也可以为其它行业的生产提供装备,社会上有着各种各样的机械或机械制造业的产品。
我们的生活离不开制造业,因此制造业是国民经济发展的重要行业,是一个国家或地区发展的重要基础及有力支柱。
从某种意义上讲,机械制造水平的高低是衡量一个国家国民经济综合实力和科学技术水平的重要指标。
油阀座的加工工艺规程及其夹具设计是在学完了机械制图、机械制造技术基础、机械设计、机械工程材料等基础课程之后的下一个教学环节。
正确地解决一个零件在加工中的定位,夹紧以及工艺路线安排,工艺尺寸确定等问题,并设计出专用夹具,保证零件的加工质量。
本次设计也要培养自己的自学与创新能力。
因此本次设计综合性和实践性强、涉及知识面广。
所以在设计中既要注意基本概念、基本理论,又要注意生产实践的需要,只有将各种理论与生产实践相结合,才能很好的完成本次设计。
这也是对我们很好的一次检验。
由于个人能力所限、实践经验少、资料缺乏,设计中有许多不足之处,敬请老师们批评指导。
第1部分引言机械制造业是国民经济的支柱产业,现代制造业正在改变着人们的生产方式、生活方式、经营管理模式乃至社会的组织结构和文化。
生产的发展和产品更新换代速度的加快,对生产效率和制造质量提出了越来越高的要求,也就对机械加工工艺等提出了要求。
在实际生产中,由于零件的生产类型、形状、尺寸和技术要求等条件不同,针对某一零件,往往不是单独在一种机床上用某一种加工方法就能完成的,而是需要经过一定的工艺过程。
因此,我们不仅要根据零件具体要求,选择合适的加工方法,还要合理地安排加工顺序,一步一步地把零件加工出来。
1.1机械加工工艺规程制订1.1.1生产过程与机械加工工艺过程生产过程是指将原材料转变为成品的全过程。
它包括原材料的运输、保管于准备,产品的技术、生产准备、毛坯的制造、零件的机械加工及热处理,部件及产品的装配、检验调试、油漆包装、以及产品的销售和售后服务等。
油阀座毕业说明书
章、所给定的零件是凿岩机注油器上的油阀座,左端通过Rc3/4与主机相连,一管套穿过油壶壳体与Φ24.513.0+㎜孔焊接,高压气体从左端进入阀座,在负压作用下,油壶内油从Φ2㎜孔流至Φ22㎜孔与高压气体混合后成雾状从套管喷出。
Φ16H10孔装入油量调节装置,缺口标志油量调节范围。
油阀座共有两组加工表面。
现分述如下:第一组加工表面包括:1、Φ63㎜的外圆,Φ24.513.0+㎜的内孔,2、Φ22㎜的内孔以及Rc3/4锥孔,3、60°锥角,1×45°倒角,4、2个Φ2㎜的通孔,一个Φ5㎜,一个Φ3㎜孔图1.1 油阀座章、零件材料为ZG45,采用砂型机器铸造。
从文献[1]中可查出其公差等级为IT8~IT10,尺寸公差1.6~3.2㎜,加工余量4~5㎜,毛坯为实心,以如图的过水平中心线与Φ24㎜圆柱体相垂直的平面为分型面。
加工前进行退火处理。
由于零件年产量为60000件,已达到大批生产的水平,而且零件的轮廓尺寸不大,故可采用砂型机器铸造。
这从提高生产率、保证加工精度上考虑,也是应该的。
基面选择是工艺规程设计中的重要工作之一。
基面选择得正确与合理,可以使加工质量得到保证,生产率得以提高。
否则,加工工艺过程问题百出,更有甚者,还会造成零件大批报废,使生产无法正常进行。
如图2.1图2.1 分型面作为粗基准的表面应平整,没有飞边、毛刺或其它表面欠缺。
对一般的轴类零件而言,以外圆作为粗基准是完全合理的,本零件选用不加工表面Φ32外圆柱面作为粗基准。
采用Φ32外圆柱面作为粗基准加工内孔可以保证空的壁厚均匀,而且便于装夹。
主要应该考虑基准重合的问题。
阀座的右端面和Φ22孔既是装配基准,又是设计基准,用它们作精基准,能使加工遵循“基准重合”的原则,实现阀座零件“一面两孔”的典型定位方式;其余各面和孔的加工也能用它定位,这样使工艺路线遵循了“基准统一”的原则。
图2.2 主要加工尺寸油阀座零件材料为ZG45,强度和切削性能良好,塑性、韧性较低。

The main stage as well as the pilot stage are designed on the proven poppet seat design, which ensures that the cartridges are leak-tight from B to A. The straightforward design delivers an outstanding price/performance ratio and good pressure loss/volume flow ratings. All external parts of the screw-in valves are zinc-nickel plated andare thus suitable for use in the harshest operating en-vironments. The slip-on coils can be replaced without opening the hydraulic envelope and can be positioned at any angle through 360º. These valves are used in mobile and industrial applications where leak-tight shutoff functions are crucially important. Examples are where loads, tensions, or clamping forces must be held without leakage. For self-assembly, please refer to the section related data sheets.SymbolTechnical DataNOTE!The switching safety of the valve is achievedby the volume flow and pressure drop (Δp).NOTE!The switching time can be strongly de-pendent on flow rate, pressure, oil viscosity and the dwell time under pressure.

General DescriptionThe DSH101C and DSH101N 2-way, poppet-type, solenoid valves are used in applications requiring on/ off valves and low leakage. Single acting cylinder applications typically utilize valves of this type. Valves can be used for bleed down flow and/or raising and lowering a vertical cylinder. Normally open and nor-mally closed configurations plus manual overrides are available.OperationNormally ClosedThe valve pilot is held on its seat by spring force, blocking pilot flow. This allows pressure at the inlet to hold the poppet on its seat, thus, preventing flow through the valve (inlet to outlet). When the coil is energized, the valve pilot is pulled off its seat. This vents pressure inside the poppet to the outlet port, creating a pressure imbalance across the main poppet which allows flow from the inlet to the outlet. Normally Closed, Fast ResponseThe operation of this version is identical to the nor-mally closed valve except for the travel of the poppet. The distance that the poppet travels is much shorter. This gives the fast response valve a faster opening time and a reduced maximum flow rate.Normally OpenThe valve pilot is held off of its seat by spring force. Pilot flow is vented to the outlet port, creating a pressure imbalance that moves the main poppet off it’s seat, allowing flow from the inlet to the outlet. When the coil is energized, the valve pilot and main poppet are forced to close, thus blocking flow from the inlet to the outlet.Features•Low hysteresis•Replaceable, one piece encapsulated, coils with minimal amperage draw•Variety of coil terminations and voltages •Variety of manual override options availableSpecificationsRated Flow DSH101CH & DSH101CHR30 LPM (8 GPM)All other versions60 LPM (15 GPM)Maximum Inlet345 Bar (5000 PSI) - Steel Pressure210 Bar (3000 PSI) - Aluminum Leakage10 drops/min.

During fueling the valve allows flow until the internal pressure of the drum reaches 4.5 ± 0.5 psi at which time the valve stops the in-flow of fuel. The valve allows for the mating of a standard underwing refueling nozzle for the filling and emptying of the drum. During defueling or emptying, the valve opens with the application of a negative pressure augmented by the positive tank pressure to allow the flow of fuel from the drum.3.0 SAFETYINFORMATIONThe Carter Fuel-Defuel Valve, 61499, is designed to mate with any standard underwing nozzle, commercial or military. These nozzles are designed to be interlocked with the adapter on the 61499. That is, if the nozzle is connectedto the 61499 and opened, it should be impossible to remove the nozzle from the valve. This is accomplished by the interaction of three interlock pins engaging into the three slots in the valve’s adapter. Excessive wear on these slots can defeat the interlock system causing an inadvertent disconnect with a possibly open nozzle. This can result in a spillage of fuel. The adapter on the 61499 should be periodically inspected to assure that the wear experienced by the connection of the nozzle is not sufficient to cause this disonnect.The following inspections of the valve adapter are recommended to be carried out at each refueling operation to assure that one is connecting to a safe adapter:A. Visually check for bent, broken, missing or excessively worn lugs or slots.Worn slots are easily detected. A normalslot will have a slight machine brokenedge (chamfer of .030 inch (0.762 mm)).If the edge is worn such that the corner isbadly distorted and enlarged it should beinspected more closely and accurately.Carter Adapter Wear Gauge, 61657-2,should be utilized to check the width andthickness of the lugs if they appear to beworn. Wear of the thickness dimension ofthe lug will promote premature nose sealleakage. Wear of the width of the lugcombines with slot wear in defeating thenozzle interlock.B. Visually check the three slots forexcessive wear. Excessive wear canpermit disengagement of a nozzlewithout release of the three interlock pinsand may permit accidental poppetopening on the disconnected nozzle. Theuse of Carter Gauge 61657-2 will providea "no-go" check for the slots.C. If any of the above conditionsare observed, and or the gaugeproves the adapter to be defective, therefueling operation should becontinued only with extreme caution.4.0 DISASSEMBLY4.1 Remove Dust Cap (1) from unit only ifreplacement is needed.4.2 Remove Screws (2) using a torquewrench.

Auto Reset SettingThe function described in this paragraph concerns only those who want to obtain the maximum dispensing stop precision in AUTO mode.If a slight excess of the pre-set value (a few hundredths of a quart) does not cause any problem, the following paragraphs can be ignored.The Meter in AUTO mode allows the user to obtain a highly precise stop, thus dispensing exactly the pre-set amount without exceeding the PRESET value.To guarantee this high stop precision, especially when the unit operates at the maximum allowed flow rates, dispensing does not stop when the PRESET value is reached, but instead when the PRESET value reaches a few Unit hundredths.To guarantee the stop precision, this pre-stop value must not be fixed , but is dependent on the flow rate used. To allow the operator to obtain the highest stop precision, the unit is equipped with a Stop Precision factor, called PS factor.The operator can customize the Meter to select a PS factor between ZERO and FOUR.E9T E C H N I C A L D E T A I L SI N T E N D E D U S EF A C T O R Y S E T T I NG S T O O L U S EE X P L O D E D A N D P A R T S L I S TO P E R A T I O N T R O U B L E S H O O T I N G G U I D E Why calibrate?If the METER is used:• With fluids having a viscosity close to the limits of the allowed range (such as low-viscosity antifreeze fluids or high-viscosity oils for gear boxes).• In extreme flow rate conditions (close to the min. and max. value of the allowed range), it may be necessary to carry out an on-site calibration.How to calibrateThe Meter allows the user to carry out a rapid electronic calibration by modifying the Calibration factor (K Factor).At delivery all meters are given the same calibration factor:K Factor = 1.000This calibration factor guarantees the best accuracy in the following operating conditions:Fluid: Motor oil type 10W 30 Temperature: 68°F Flow-rate: 2.6 GPM The calibration can be done either as:• An on-site calibration by dispensing into a calibrated container or During dispensing the Meter displays: Batch Total dispensedBlinking3.21LitCALT E C H N I C A L D E T A I L SI N T E N D E D U S EF A C T O R Y S E T T I NG ST O O L U S EE X P L O D E D A N D P A R T S L I S TT R O U B L E S H O O T I N G G U I D EE10E11TECHNICALDETAILS I N T E N D E D U S E FACTORYSETTINGS T O O L U S EEXPLODEDANDPARTSLIST O P E R A TI O N TROUBLESHOOTINGGUIDED.

机械制造业的产品既可以直接供人们使用,也可以为其它行业的生产提供装备,社会上有着各种各样的机械或机械制造业的产品。
我们的生活离不开制造业,因此制造业是国民经济发展的重要行业,是一个国家或地区发展的重要基础及有力支柱。
从某中意义上讲,机械制造水平的高低是衡量一个国家国民经济综合实力和科学技术水平的重要指标。
油阀座的加工工艺规程及其夹具设计是在学完了机械制图、机械制造技术基础、机械设计、机械工程材料等进行课程设计之后的下一个教学环节。
正确地解决一个零件在加工中的定位,夹紧以及工艺路线安排,工艺尺寸确定等问题,并设计出专用夹具,保证零件的加工质量。
本次设计也要培养自己的自学与创新能力。
因此本次设计综合性和实践性强、涉及知识面广。
所以在设计中既要注意基本概念、基本理论,又要注意生产实践的需要,只有将各种理论与生产实践相结合,才能很好的完成本次设计。
由于个人能力所限、实践经验少、资料缺乏,设计尚有许多不足之处,敬请老师们批评指导。
1零件图工艺性分析1.1对被加工零件进行工艺分析通过对该零件图的重新绘制,知原图样的视图正确、完整,尺寸、公差及技术要求齐全。
但 24.5的孔要要求精度高要精镗,没有退刀槽,应该加上。
由零件图可知,该零件结构简单,但技术要求多,对基准的选择要求高,零件选用材料ZG45,该材料具有较高的强度,韧性和塑性,切屑性能良好,结构工艺性好。
阀门制造工艺有如下特点:①阀门毛坯的制造工艺及检验工艺比较复杂。
阀门的铸件毛坯是结构叫复杂的薄壁壳体件。
其铸件要求表面光洁、铸字清晰,特别是要有致密的缺陷。
为了满足上述要求,铸造时应采取一系列工艺措施,如选用高耐火度的造型材料并控制型砂水份、造型时应分层打实以保证砂型硬度,采用合理的浇帽口系统及严格控制浇注速度和温度等。
由于技术要求较高,阀门毛坯的铸造工艺远较一般铸件复杂。
此外,阀门毛坯除检查尺寸,位置精度及外观外,有的还有作金相组织、力学性能、耐腐蚀性能及无损探伤等多种检验,故阀门的检验工艺也较复杂。
②机械加工难度大由于阀门材料的各类繁多,除各种铸铁、碳素钢外,其大部分高强、耐腐蚀和高硬材料的切削性能都很差,很难使零件达到规定的加工精度和表面粗糙度。
而阀门密封面的几何型状精度和表面粗糙度的要求很高,因此更增加了阀门机械加工难度。
同时,阀门材料的切削性能差,又给阀门的加工方法、刀具材料、切削用量、工艺装备等方面带来了很多新的问题。
③阀门零件在机床上安装比较困难阀门主要零件的结构、形状比较复杂,有些零件属壁薄、细长件,刚性差。
在机床上加工时,定位和装夹都比较困难,因此往往需要复杂的专用夹具。
有的阀门零件,定位基面的精度较低,表面粗糙度较高,有时甚至采用非加工表面定位。
而被加工密封面等部位的精度和表面粗糙度要求都很高,故得难保证加工质量。
因此,为满足工艺上的需要,往往须提高定位基面的精度和降低表面粗糙度,或在非加工表面上加工出定位基面,这就增加了阀门制造工艺的复杂性。
1.2主要加工表面及技术要求分析1.22作为基准∅孔,而且孔径小,要钻出,同一道工序加工∅24、∅63、∅3、∅5、∅2。
同时保证∅22与∅3的距离23.5和∅22与∅2的距离22,还有保证内孔和外圆同轴。
2.上孔加工保证同轴,而且保证∅16和右端面的距离22。
上孔的加工基准为右端面。
3.各段孔之间要求相互垂直都是通孔。
图1.1零件图2 确定毛坯2.1 毛坯分析根据零件材料ZG45确定毛坯为铸件,为了保证孔∅22的加工质量和便于加工,将整个工件铸成整体毛坯,分型面通过∅22孔中心线,而且垂直∅16孔的中心线,铸件进行人工时效后,送机加工车间加工,以免工件切开后发生较大的变形。
2.2 铸件尺寸公差由于是中批量生产,毛坯制造选方法采用砂型机器型,由工艺人员手册查得,铸件尺寸公差等级为CT10,选取铸件错箱值为1.0 mm 。
2.3 铸件机械加工余量计算对于批量生产的铸件加工余量由工艺人员手册查得选取MA 为G 级,各表面的总余量见下表1.1,由工艺人员手册查得铸件主要尺寸见表2.2。

另外右端面也是加工左端面和钻Φ16孔精基准。
(2)粗基准的选择:粗基准应为一些非加工面,为了保证壁厚均匀及Φ22 孔的位置精度,故选Φ30轴面作为粗基准。
3.2.表面加工方法选择对于开螺母下座的主要加工表面是导轨面及孔和端面其加工方法如下:(1)右端面采用粗铣,半精铣。
(2)Φ22孔采用钻孔,粗镗,Φ24孔采用粗镗,半精镗,精镗。
(3)左端面采用粗铣,半精铣,倒角。
(4)上端面及缺口采用粗铣,半精铣。
(5)Φ16 钻IT11粗糙度为12.5铰IT9粗糙度为3.2,Φ16.8精镗孔。
(6)Φ2 钻Φ3钻IT11粗糙度为2.5(7)惚平Φ22攻Rc3/4螺孔3.3.制定工艺路线工艺路线的确定,本着先基准后其它,先孔后面,先主要表面后次要表面,和先粗后精的加工原则。
1.工艺路线方案一10 粗车右端面,半精车右端面。
粗车及半精车外圆Φ6320 粗车,半精车左端面,倒角30 钻Φ22孔,倒角、攻螺纹40 扩孔Φ24.5,粗镗退刀槽,精镗孔Φ24.550 钻Φ3,Φ5,Φ2孔60 粗铣,半精铣上表面70 钻Φ10.5孔,扩Φ16孔80 铣Φ16孔下端面,铣上端面平台90粗镗孔Φ24(退刀槽)半精镗孔Φ16,钻Φ2孔2.工艺路线方案二10 粗车右端面,半精车右端面。
粗车及半精车外圆Φ6320 扩孔Φ24.5,粗镗退刀槽,精镗孔Φ24.530 钻Φ3,Φ5,Φ2孔40 粗车,半精车左端面,倒角50 钻Φ22孔,倒角、攻螺纹60 粗铣,半精铣上表面70 钻Φ10.5孔,扩Φ16孔80 铣Φ16孔下端面,铣上端面平台90粗镗孔Φ24(退刀槽)半精镗孔Φ16,钻Φ2孔述两个工艺方案的特点在于:方案一是先集中加工工序,在各个机床上操作的工序都完成后,再进行下一机床的加工,该方案需要经常更换夹具,不经济。
方案二虽然可以直接做出Φ24.5孔,少一次装夹,但不能保证精度,出于精度考虑。
选择加工方案一。
首先以不加工面Φ32面作粗基准来粗加工右端面及Φ63,这样能保证壁厚均匀及Φ22与Φ6.的同轴度,以右端面为基准一侧限制一个移动自由度。
以底面上一支支撑钉配合心轴限制一个转动自由度,来精加工左端面倒角然后钻Φ22孔及攻螺纹,扩孔粗加工Φ24.5及退刀槽。
然后钻Φ2、Φ3、Φ5孔。
再以一长心轴在Φ22 孔中定位,。
钻孔Φ2、Φ10.5、Φ16退刀槽及精加工Φ16 ,然后铣平台。
3.4.选择加工设备及工艺装备由于是中批量生产,故加工设备以通用机床为主,其生产方式以通用机床专用夹具为主,工件在个机床上的装卸及个机床间的传送均由工人完成。
(1)右端面,考虑到工件的定位加紧方案等问题,选用CA6140车床,端面车刀。
(2)车Φ63、钻Φ22孔,外圆车刀,Φ22麻花钻。
(3)车左端面、倒角、攻螺纹,端面车刀。
(4)铣上端面,升降台式铣床。
(5)钻Φ16孔、Φ16孔、Φ2孔,Φ16麻花钻,用Z518立式钻床,钻模塞规。
(6)惚平Φ16平台,用立式升降台铣床。
