钻头工具动力刀座传动零件基座的锻造工艺设计摘要动力刀座体系是打桩机工具最巨大的构成要素，它的产品功效好坏直接作用钻头工具整机的运转功用。然而在打桩机工具动力刀座设计工艺上，国内主机厂起步较晚，经验缺乏，缺少测试探索，致使动力刀座使用历程中障碍率高，可靠性缺乏。所以，深入探索动力刀座设计理论，改善解析它的构造中欠缺环节，提升动力刀座的可靠性，对提高打桩机工具整机运转功用有着巨大意义。论文首先阐述了动力刀座构造的构成、功用和理论，对比解析了国内外打桩机工具动力刀座的典型构造，找出不同构造之间的差异，为动力刀座设计提供参考。然后，以XR220D打桩机工具为样机，设计了动力刀座，运用三维语言程序Creo创建动力刀座传动零件基座、传动齿轮和设备驱动程序的样式。在此前提之上，借助有限单元解析语言程序ANSYS对动力刀座的关键零部件进行了理论力学解析，以了解它的不同工况下的内力、形变织构分布状况，进而找出构造中的欠缺环节，为动力刀座的改善提供根据。有限单元解析成效显示：动力刀座传动零件基座和设备驱动程序的上限内力值超过了原料的许用内力值，极限工况下容易遭到破坏，是构造的欠缺所在地。对动力刀座内旋转的关键基本单元进行模态解析，得到了前六阶固有单位时间内完成重复出现变化的次数，说明动力刀座旋转件不会发生共振。最后，本文针对动力刀座构造的欠缺环节进行改进改善，改善后验证性的进行有限单元解析，对比改善前后欠缺环节的内力，成效显示动力刀座传动零件基座和设备驱动程序的上限内力值显著下降，改善后的上限内力值都在许用内力值之下，验证了改善参数的合理性。关键词：打桩机工具，动力刀座，构造设计，有限单元解析，改善abstractThepowertoolbasesystemisthemostimportantcomponentofthepiledrivertool,anditsproductefficiencydirectlyaffectstheworkingfunctionofthewholedrilltool.However,inthedesignprocessofpowertoolholderofpiledriver,thedomesticmainenginefactoriesstartedlate,lackedexperienceandtestexploration,resultinginhighfailurerateandlackofreliabilityintheuseprocessofpowertoolholder.Therefore,itisofgreatsignificancetodeeplyexplorethedesigntheoryofdynamictoolholder,toimprovetheanalysisofthelackoflinksinitsconstructionandtoenhancethereliabilityofdynamictoolholderforimprovingtheworkingfunctionofpiledrivertools.Firstly,thepaperexpoundsthestructure,functionandtheoryofdynamictoolseat,comparesandanalysesthetypicalstructureofdynamictoolseatofpiledriverathomeandabroad,findsoutthedifferencebetweendifferentstructures,andprovidesreferenceforthedesignofdynamictoolseat.Then,takingtheXR220Dpiledrivertoolasaprototype,thepowertoolholderisdesigned,andthethree-dimensionallanguageprogramCreoisusedtocreatethemodelofthepowertoolholderbox,transmissiongearanddrivesleeve.Onthispremise,thekeypartsofthepowertoolseatareanalyzedtheoreticallyandmechanicallywiththeaidofANSYSprogram,soastounderstandthedistributionofinternalforceanddeformationtextureunderdifferentworkingconditions,andthenfindoutthedeficienciesinthestructure,soastoprovideabasisfortheimprovementofthepowertoolseat.Theresultsoffiniteelementanalysisshowthatthemaximuminternalforceofthepowertoolseatboxandthedrivesleeveexceedstheallowableinternalforceoftherawmaterial,andiseasilydamagedunderthelimitcondition,whichisthelackofthestructure.Bymodalanalysisofthekeybasicelementsoftherotationinthepowertoolholder,thenumberoftimesthatthefirstsixorderinherentunittimecompletestheperiodicchangeisobtained,whichshowsthatthepowertoolholderrotatingpartswillnothaveresonance.Finally,thispaperimprovesthedeficiencylinkofthepowertoolseatstructure,carriesonthefiniteelementanalysisaftertheimprovement,comparestheinternalforceoft...
