Ob lub rooj teb thiab lub taub hau indexing (tseem hu ua lub taub hau faib) yog ua haujlwm -cov cuab yeej siv feem ntau siv rau ntawm cov tshuab milling thiab machining chaw, thiab ob qho tib si tig ib qho chaw ua haujlwm nyob ib ncig ntawm txoj kab rov tav kom nthuav tawm lub ntsej muag sib txawv lossis lub kaum sab xis rau lub tshuab txiav. Tab sis lawv tau tsim nyob ib ncig ntawm cov ntsiab lus sib txawv. Arotary roojyog qhov tseem ceeb ntawm lub tiaj tus, qhov tseeb - hauv av ncig disc nrog T- qhov chaw nyob rau sab saum toj - workpiece bolts ncaj qha mus rau lub rooj saum npoo, thiab tag nrho cov disc tig rau ntawm tus cab - thiab - lub log tsav. Ibindexing taub hauyog tsim nyob ib ncig ntawm ib tug kab rov tav spindle haum nrog ib tug chuck (feem ntau yog ib tug 3- puab tsaig self-centering chuck) los yog ib tug faceplate, feem ntau ua ke nrog ib tug tailstock los txhawb qhov deb kawg ntawm workpieces ntev. Lub spindle, tsis yog lub rooj tiaj tus, yog dab tsi tuav thiab tig qhov. Qhov sib txawv tseem ceeb ntawm qhov ua haujlwm ntawm lub tshuab ua haujlwm li cas txiav txim siab yuav luag txhua yam ntxiv txog yuav ua li cas ob lub cuab yeej ua haujlwm thiab siv qhov twg.
Lawv tuav lub workpiece li cas
Qhov sib txawv ntawm kev ua haujlwm yog qhov sib txawv tshaj plaws. Ntawm lub rooj teb, qhov chaw zaumnyob saumntawm lub rooj thiab yog clamped nrog T-slot bolts, straps, los yog ib tug vise mounted rau lub rooj. Qhov no ua rau nws zoo tagnrho rau lub tiaj, loj, lossis qhov tsis sib xws - flanges, valve lub cev, pwm phaj, brackets, thiab loj castings - uas tsis tuaj yeem yooj yim tuav hauv chuck. Lub rooj siv tau nyob rau hauv txoj hauj lwm kab rov tav (rotating ib ncig ntawm ib tug ntsug axis) los yog sawv ntawm qhov kawg rau ntsug -axis ua hauj lwm. Ntawm lub taub hau indexing, ib feem yog tuavhauv chucklos yog nruab nrab ntawm cov chaw, zoo li lub tshuab dhos. Qhov no yog txoj hauv kev zoo los tuav puag ncig, ncej- hom, lossis qhov sib luag - iav blanks, splined shafts, bolts, txiav cov cuab yeej, mandrels - thiab cov tailstock muab kev txhawb nqa nruj rau cov ncej ntev uas yuav txwv tsis pub cuam tshuam hauv kev txiav quab yuam. Lub taub hau indexing spindle feem ntau tuaj yeem tig los ntawm hauv qab kab rov tav (txog -}10 degree) mus txog 90℃ntsug, tso cai sib xyaw- lub kaum sab xis, tab sis nws yog qhov cuab yeej kab rov tav-axis.
Lawv tsim los ua dab tsi
Dhau li ntawm kev ua haujlwm, ob lub cuab yeej muaj qhov sib txawv tsim ua ntej. Lub rooj teb yog tsim rautswj tsis tu ncua kev sib hloov raws li indexing. Lub rooj tuaj yeem ua kom qeeb qeeb thaum lub tshuab txiav tau koom nrog - los zeb ib ncig arc, lub cam profile, nkhaus qhov, los yog helical feature - los yog nws tuaj yeem kaw ntawm ib lub kaum ntse ntse rau drilling lossis tho txawv. Qhov no ua rau nws muaj ntau yam machining platform, tsis yog tus positioner xwb. Ib lub taub hau indexing yog tsim rau feem ntauindexing- tig lub workpiece mus rau ib tug meej angular txoj hauj lwm, xauv nws, thiab ua ib tug txiav, ces rov ua dua. Nws yog optimized rau faib ib lub voj voog rau hauv vaj huam sib luag ntu (6 iav hniav, 12 splines, 6 flats ntawm lub taub hau ntsia liaj qhov rooj) es tsis txhob txiav thaum tig. Feem ntau lub taub hau indexing txhawb ntau txoj hauv kev indexing - ncaj qha indexing, yooj yim indexing siv lub qhov phaj, sib txawv indexing rau prime tooj, thiab compound indexing - tab sis lawv tsis yog tsim rau du, nruam rotation nyob rau hauv load. Ib lub rooj teb tuaj yeem ua ob qho tib si txuas ntxiv thiab indexing; lub taub hau indexing ua indexing exceptionally zoo tab sis yog ib qho kev xaiv tsis zoo rau arc milling.
Qhov tseeb thiab Indexing Methods
Ob lub cuab yeej siv cov cab cab - thiab - lub log tsav (feem ntau 40: 1, qee zaum 60: 1 lossis 90: 1) los txo cov tes-crank motion rau hauv zoo angular txav, tab sis lawv ua tiav qhov sib txawv. Ib phau ntawv teb lub rooj feem ntau nyeem lub kaum sab xis ntawm avernier nplaintawm lub log, nrog rau kev nyeem ntawv daws teeb meem txog li 1 arc-feeb (± 2 arc- feeb raug raug) - zoo rau kev ua haujlwm dav dav tab sis txwv los ntawm qhov ua tau zoo npaum li cas tus neeg teb xov tooj tuaj yeem nyeem cov nplai. Lub rooj sib tham CNC siv lub servo lub cev muaj zog thiab kaw - voj encoder, ua tiav ± 10 arc- vib nas this lossis zoo dua nrog tsis txwv, software-txhais chaw. Ib lub taub hau indexing siv ibindex phaj(ib lub voj voog uas muaj ntau lub voj voog ntawm qhov sib luag ntawm qhov sib txawv) thiab cov caj npab los suav cov haujlwm ntawm lub qhov, uas ua rau nws muaj peev xwm rov ua tau zoo dua - lub taub hau faib zoo tuaj yeem tuav ± 30 arc- vib nas this nrog cov phaj kom raug - thiab tso cai rau kev faib tawm uas yooj yim vernier tsis tuaj yeem ncav cuag, suav nrog cov lej tseem ceeb ntawm qhov sib txawv indexing. Kev lag luam tawm yog lub sijhawm teeb tsa: hloov pauv suav rau ntawm lub taub hau indexing txhais tau tias xaiv lub voj voog ntawm lub phaj thiab rov pib dua kev lag luam caj npab (10-20 feeb rau ib txoj haujlwm), thaum lub rooj teb yog zeroed thiab npaj tau li ntawm tsib feeb.
Tej kev siv
Hauv kev xyaum, ob lub cuab yeej muaj peev xwm tswj hwm cov tsev neeg sib txawv.Rotary roojyog qhov mus-rau kev xaiv rau: milling ncig arcs, radii, thiab cam profiles; drilling los yog tapping ntsia liaj qhov rooj - lub voj voog ntawm flanges thiab manifolds; machining valve lub cev, twj tso kua mis vaj tse, thiab pwm daim hlau uas xav tau angular nta ntawm lub ntsej muag tiaj tus; tsim cov qhov nkhaus, lub zog txiav los ntawm kev nruam- txoj kev sib hloov, thiab helical contours; thiab ua haujlwm raws li CNC plaub axis rau ib txhij 4-axis milling ntawm complex 3D nto.Indexing taub haudominate nyob rau hauv: milling iav hniav (spur, bevel, thiab cab iav) ntawm iav blanks; milling splines thiab keyways ntawm shafts; txiav flats ntawm hex bolts, txiv ntseej, thiab cov cuab yeej khoom; drilling sib npaug spaced qhov nyob ib ncig ntawm lub circumference ntawm ncej-mounted qhov chaw; machining clutches, ratchets, thiab serrations; thiab txiav threads thiab tapers thaum teem rau helical milling. Lub taub hau indexing chuck-thiab-tailstock teeb yog qhov tseem ceeb ntawm lub tshuab dhos me me ntawm lub rooj zeb, uas yog raws nraim li cov ncej- hom haujlwm xav tau.
Xaiv Ntawm Lawv
Qhov kev txiav txim siab feem ntau yog los ntawm qhovworkpiece puabthiab covhom kev ua haujlwm. Yog tias koj qhov chaw ua haujlwm feem ntau yog tiaj tus lossis loj qhov chaw - flanges, daim hlau, vaj tse, pwm - lossis yog tias koj xav tau txiav arcs thiab nkhaus profiles thaum lub sij hawm tig, lub rooj teb yog cov cuab yeej zoo, thiab nws kuj muab rau koj xaiv CNC plaub -axis muaj peev xwm tom qab. Yog tias feem ntau ntawm koj txoj haujlwm yog ncej- hom lossis qhov sib luag - lub zog, splines, bolts, cov cuab yeej txiav - thiab cov haujlwm tseem ceeb yog faib ua ntu sib npaug, lub taub hau indexing muab nrawm dua, rov ua dua indexing nrog kev txhawb nqa zoo dua rau qhov ntev ntawm tailstock. Ntau lub khw muag khoom thaum kawg muaj ob qho tib si, vim tias lawv ntxiv ntau dua li kev sib tw: lub rooj sib txuas ua haujlwm ncaj nraim thiab txuas ntxiv - kev sib hloov ua haujlwm, lub taub hau indexing tuav puag ncig thiab siab - faib- suav indexing. Rau thawj qhov kev yuav khoom lossis kev siv nyiaj tsawg, cov lus teb feem ntau yog qhov kev xaiv ntau yam vim tias nws tuaj yeem ua indexing ntxiv rau arc milling, thaum lub taub hau indexing tsis tuaj yeem ua kom du nruam txiav. Rau ib lub khw tsom rau cov iav thiab spline ntau lawm, lub taub hau indexing yog cov cuab yeej tshwj xeeb thiab tsim khoom.
Xaus
Rotary rooj thiab indexing taub hau ob leeg tig workpieces rau milling, tab sis lawv teb cov lus nug sib txawv. Lub rooj teb yog lub tiaj tus, T-slotted disc uas tuav qhov chaw ntawm nws qhov chaw thiab tsim rau ob qho tib si kev sib hloov tsis tu ncua (arc milling, cams, curved slots) thiab angular positioning - nws yog ntau yam dav dav - lub hom phiaj cuab yeej thiab lub ntuj platform rau CNC plaub axis. Lub taub hau indexing yog ib tug spindle-thiab-chuck ntaus ntawv, feem ntau nrog ib tug tailstock, tsim tshwj xeeb rau high -precision sib npaug- faib indexing ntawm gears, splines, polygons, thiab ncej- hom qhov chaw, siv index daim hlau thiab sector caj npab kom cuag tau repeatability uas yooj yim vernier. Xaiv raws li qhov koj ua: tiaj tus thiab arcs taw tes rau lub rooj teb; puag ncig qhov chaw thiab sib npaug sib faib taw qhia rau lub taub hau indexing. Nyob rau hauv ib lub qhov dej -chaw tsim khoom, ob qho tib si ua haujlwm ntawm ib sab, txhua tus tuav haujlwm rau lwm tus tsis tau tsim rau.
