麻花鉆刃磨裝置的設(shè)計說明書.doc

I摘要通過對實際情況的分析調(diào)查以及對現(xiàn)有麻花鉆刃磨方法的比較和研究，采用內(nèi)錐面刃磨麻花鉆的方法。本設(shè)計闡述了內(nèi)錐面刃磨麻花鉆的刃磨原理、刃磨參數(shù)和工藝方案的確定、主軸轉(zhuǎn)速的計算、砂輪的選取與安裝等一系列問題，從而在研究分析的基礎(chǔ)上參考現(xiàn)有主要磨床的設(shè)計和改造方法，以及結(jié)合內(nèi)錐面刃磨鉆頭進行的一些實驗和目前在鉆頭刃磨技術(shù)方面所得的成果，設(shè)計出了合理有效、安全可靠、經(jīng)濟簡捷的麻花鉆內(nèi)錐面刃磨裝置。關(guān)鍵詞：麻花鉆；內(nèi)錐面刃磨；刃磨裝置設(shè)計IIAbstractAccordingtotheactualsituationanalysisinvestigationandexistingtwistdrillgrindingmethodofcomparisonandresearch,withtheinnerconegrindingoftwistdrillmethod.Theelaboratedesignoftheinnerconegrindingoftwistdrill,thegrindingprincipleofgrindingparametersandtheidentificationprocess,thecalculationofgrindingwheelspindlespeed,theselectionandinstallationandaseriesofproblems,andonthebasisofresearchandanalysiswithreferencetotheexistingmaingrinderdesignandmodificationmethods,andcombiningwiththeinnerconegrindingdrillsomeexperimentsandpresentindrillgrindingtechnologyresults,andprovethefeasibilityofthedesign,designareasonableandeffective,safeandreliable,economicandsimpleinnerconegrindingoftwistdrilldevice.Keywords:twistdrill；theinnerconegrinding；grindingdevicedesignIII目錄摘要.IAbstract.第1章緒論.-1-1.1設(shè)計麻花鉆刃磨裝置的意義.-1-1.2麻花鉆刃磨技術(shù)研究概述.-1-1.2.1麻花鉆刃磨裝置國內(nèi)外發(fā)展狀況與趨勢.-1-1.2.2存在的主要問題.-4-1.3麻花鉆刃磨方法的比較.-5-第2章麻花鉆內(nèi)錐面刃磨的理論分析.-6-2.1麻花鉆的幾何特性.-6-2.1.1麻花鉆的結(jié)構(gòu).-6-2.1.2麻花鉆的幾何參數(shù).-7-2.2麻花鉆的傳統(tǒng)刃磨方法.-8-2.3麻花鉆的內(nèi)錐面刃磨方法.-9-2.4麻花鉆的內(nèi)錐面刃磨原理及.-10-刃磨參數(shù)優(yōu)化.-10-2.4.1鉆頭刃磨原理.-11-2.4.2刃磨參數(shù)的優(yōu)化.-11-第3章麻花鉆刃磨裝置的機械系統(tǒng)設(shè)計.-13-3.1刃磨裝置的總體方案.-13-3.2絲杠螺母副的設(shè)計計算.-14-3.2.1橫縱向進給的設(shè)計計算.-14-3.2.2垂直進給的設(shè)計計算.-19-3.3傳動系統(tǒng)的錐齒輪設(shè)計計算.-23-3.3.1橫向進給方向上錐齒輪的設(shè)計.-23-3.3.2垂直進給方向上錐齒輪的設(shè)計.-27-3.4導軌的設(shè)計計算.-31-第4章麻花鉆裝夾及分度裝置設(shè)計.-32-第5章電動機及砂輪的選擇.-41-IV5.1電動機的選擇.-41-5.2砂輪的選擇.-41-結(jié)論.-43-致謝.-44-參考文獻.-45-VContentsAbstract.IChapter1introduction.-1-1.1Theresearchpurposeandmeaningofdesigningtwistdrill.-1-1.2researchanoverviewoftwistdrillgringingtechnology.-1-1.2.1Overviewoftwistdrillsharpeningdevice.-1-1.2.2Themainproblems.-4-1.3Compareoftwistdrillgrindingmethod.-5-Chapter2Thetheoreticalanalysisoftwisttheinnerconegrinding.-6-2.1Geometricpropertiesofthetwistdrill.-6-2.1.1Structureofthetwistdrill.-6-2.1.2Geometricparametersofthetwistdrill.-7-2.1Thetraditionalgrindingmethodofthetwistdrill.-8-2.3Theinnerconegrindingmethodofthetwistdrill.-9-2.4Theinnerconegrindingtheoryofthetwistdrilland.-10-optimizingofgrindingparameters.-10-2.4.1Theinnerconegrindingtheoryofthetwistdrill.-11-2.4.2optimizingofgrindingparameters.-11-Chapter3twistdrillgrindingequipmentmechanicalsystemdesign.-13-3.1Programofgrindingdevice.-13-3.2Designandcalculationofscrewnutpairs.-14-3.2.1Horizontalandverticalfeeddesigncalculation.-14-3.2.2designandcalculationoftheverticalfeed.-19-3.3Bevelgeardrivesystemdesigncalculation.-23-3.3.1Crossfeeddirectionbevelgeardesign.-23-3.3.2Perpendiculartothebevelgea
