抽油泵长缸套内孔加工工装设计说明书.doc

I摘要抽油泵长缸套是抽油泵的主要基础件。抽油泵工作性能主要取决于柱塞和泵套加工精度、表面质量及形状精度。本文讨论了在现有的加工条件下完成对抽油泵长缸套内孔的加工，即深孔加工，提出了车床改造的方案。简单介绍了深孔的发展概况、深孔加工系统的组成、深孔加工中的常见问题。基于以上特点，设计完成对CA6140的深孔加工改造。原来的镗滚压符合工具在加工结束移动溜板拉出工件时会在工件表面留下拉伤痕迹，影响工件表面质量及精度，且前端镗刀刀尖也比较容易损坏，因此我也对镗滚压复合工具进行了一些改进。改进后的镗滚压复合工具的结构变的比较简单，快退时不会拉伤工件表面，镗刀刀尖不易损坏，加工质量稳定，生产效率明显提高。关键词深孔加工镗滚压复合工具镗床车床改装IIAbstractCylinderjacketisthemainfoundationalpart.Theworkingperformanceofoil-wellpumpismainlydecidedonthecompoundperformanceofplungerandcylinderjacket.Thatistosay,itisdependedonthecylinderjacketworkingaccuracyroughnessofsurfaceandpositionaccuracy.Thispaperdiscusseshowtocompletethetraditionaldepthaperturecutting,thesystemoforificecuttingandtheproblemsthatappearintheorificeprocessingissimplydiscuaaed.Baseonsuchcharacters,designandcompletetheorificemachiningalterationinthetypeofCA6140.Theoriginalboring-stitchtoolswillleftsprainontheworkpiecesurfacewhenprocessingisoverandthemobileslidepullouttheworkpiece.Thiswillaffecttheworkpiecesurfacequalityandprecisionandthetipofthefrontboringisrelativelyeasytodamage,soIhavetomakesomeimprovementsontheboring-stitchtools.AfterImproved,theboring-stitchtoolsstructurearerelativelysimple,quickwithdrawalwillnotpulltheworkpiecesurface,processingqualityisstableandproductionefficiencyisimprovedsignificantly.Keywordsorificeworkboring-stitchtoolsboringmachineIII目录摘要.Abstract.第1章绪论.11.1车床改装为深孔加工的意义.11.2深孔加工技术研究概述.11.2.1深孔的定义.11.2.2深孔加工的类型、特点及要解决的主要问题.21.2.3深孔加工发展概况.41.3常用深孔加工系统及系统中的常用装置.61.4深孔加工技术的研究动态.81.5深孔的镗滚压加工.121.5.1深孔镗削加工.121.5.2深孔滚压加工.14第2章深孔加工工装设计.172.1概述.172.1.1深孔加工要求.172.1.2简述.182.1.3车床改造总体方案.192.2车床改造分析与计算.202.3机床改造结构设计.212.3.1镗滚压切削设计.222.3.2定位、夹紧装置的设计.242.3.3授油器的结构设计.292.3.4冷却排屑系统结构设计.292.4.5镗杆的设计.312.3.6镗杆固定架设计.322.3.7压板设计.33结论.34致谢.35参考文献.36IVContentsAbstract.Chapter1Introduction.11.1Lathemodifiedforthedeepholeprocessingsignificance.11.2Thedeepholeprocessingtechnologyresearchpaper.11.2.1Definitionofdeephole.11.2.2Thedeepholeprocessingthetype,characteristicsandtheimportantproblemtobesolved.21.2.3Thedeepholeprocessingdevelopmentsituation.41.3Commonlyusedthedeepholeprocessingsystemandthesystemofcommondevice.61.4Thedeepholeprocessingtechnologytrendsofresearch.81.5Deepholeboringrollingprocessing.121.5.1Deepholeboringcutprocessing.121.5.2Deepholerollingprocessing.14Chapter2Thedeepholeprocessingequipmentdesign.172.1Ofalmost.172.1.1Thedeepholeprocessingrequirements.172.1.2This.182.1.3Theoveralldesignofthelathetransformation.192.2Lathetransformationanalysisandcalculation.202.3Machinetoolsstructuredesign.212.3.1Boringrollingcuttingdesign.222.3.2Positioning,clampingdevicedesign.242.3.3Grantedthestructuredesignoftheoilpot.292.3.4Coolingscrapsdischarges
