Mechanics yog ib qho nyuaj thiab siv tau
Raws li cov duab kos, koj tuaj yeem mus tsis ncaj ncees lawm.
Yog hais tias muaj ib qho yuam kev nyob rau hauv ib qho chaw, daim ntawv thov tiag tiag yuav tsis ncaj ncees lawm.
sim koj
Koj puas tuaj yeem pom qhov yuam kev hauv daim duab no?
Hom kev kos duab kos duab
Muaj ntau ntau hom kev kos duab: schematic daim duab thiab kos duab kos duab. BOM lis. Thaum koj paub hom kev kos duab, koj tuaj yeem txiav txim siab seb nws sawv cev dab tsi thiab nws txhais li cas. Muaj pes tsawg qhov kev nthuav qhia?
Yuav ua li cas nyeem mechanical drawings?
Qhia meej seb hom kev kos duab yog dab tsi: daim duab sib dhos lossis schematic daim duab. Nws kuj tuaj yeem yog daim duab kos lossis BOM daim ntawv teev npe. Ntau hom kev kos duab muaj cov ntaub ntawv sib txawv, thiab lawv qhov tseem ceeb yog txawv.
Txhua tus neeg ua raws tib lub teb chaws cov qauv kos duab, txawm tias cov duab kos yog tib yam. Ib daim duab yog tsim los rau pej xeem saib. Nws yuav plam lub ntsiab lus yog tias nws nyuaj heev, muaj ntau qhov chaw, lossis yog tias lwm tus neeg tsis tuaj yeem nkag siab nws. Saib ntawm lub npe bar nyob rau sab xis kaum sab xis kom pom lub npe ntawm cov khoom, tus lej, qhov ntau, cov khoom siv (yog tias tsim nyog), qhov kev faib ua feem, chav tsev, thiab lwm yam ntaub ntawv ntsig txog.
Daim duab piv txwv
Txiav txim siab saib kev taw qhia. Cov duab kos duab feem ntau muaj tsawg kawg yog ib qho. Lub tswv yim ntawm kev pom yog muab los ntawm qhov projections ntawm kos duab geometry. Lub tswv yim ntawm peb qhov kev xav no yuav tsum tau nkag siab kom nkag siab cov duab kos.
Lub hom phiaj ntawm cov khoom tuaj yeem qhia tau siv lub hauv paus ntsiab lus ntawm qhov projection thiab nws tuaj yeem muab tso rau qhov twg hauv lub quadrant. Feem ntau, cov khoom yuav tsum tau muab tso rau hauv thawj plaub-square kom tau txais qhov projection. Txoj kev no yog hu ua thawj lub kaum sab xis projection. Txoj kev thib ob, thib peb, thiab plaub-lub kaum sab xis kuj tseem ua tau.
Hauv Tebchaws Europe (xws li hauv tebchaws United Kingdom thiab lub tebchaws Yelemes), txoj kev no feem ntau siv. Txoj kev thib peb yog siv los ntawm Tebchaws Meskas, Nyiv, thiab lwm lub tebchaws.
Qhov no yog lub ntsiab lus ntawm kev pom. Nws yuav tsum tau spatial kev xav thiab tsub zuj zuj. Cov lus tso dag hais tias yog tias cov khoom nws tus kheej tsis tuaj yeem rov qab los, nws yuav txaj muag rau "kev khawb qhov dej thiab tsim lub chimney". puab.
Koj tuaj yeem tau txais lub tswv yim ntawm qhov loj los ntawm kev saib sai. Koj yuav tau kuaj xyuas nws thaum koj siv nws yog tias koj yog tus tsim khoom.
Tam sim no koj tuaj yeem suav hais tias yog ib tus neeg layman yog tias koj tau nyeem cov duab kos. Koj tuaj yeem nres ntawm qhov no yog tias koj tsis xav nkag mus rau hauv cov ntsiab lus. Mechanical drawing cov ntaub ntawv yog ntau tshaj li qhov ntawd.
Mechanical Drawings
Mechanical drawings (cov duab kos yog cov qauv kev kos duab rau cov khoom) qhia cov qauv, cov khoom siv, qhov tseeb, thiab qhov ntev ntawm cov khoom. Tag nrho cov ntaub ntawv tsim rau ib feem, tshuab lossis ib feem.
Cov duab kos tseem muaj cov ntaub ntawv ntau heev, txawm tias kuv tau pom cov ntaub ntawv thiab cov khoom siv ua ntej nkag mus rau hauv kev lag luam. Phau ntawv qhia kev tsim kho tshuab yog ntau txhiab nplooj ntawv ntev, txij li yuav luag txhua cov ntaub ntawv kho tshuab muaj nyob hauv cov duab kos. Txhua qhov loj me thiab cov lus qhia tau muab ib theem ntawm qhov tseem ceeb, thiab tag nrho cov ntawm lawv sawv cev rau ntau yam kev paub hauv paus. Tus nqi ntawm cov ntaub ntawv koj tuaj yeem nkag siab yog nyob ntawm koj tus kheej cov ntaub ntawv.
Qhov tseeb hauv cov khoom kos duab
Mechanical qhov ntev, xws li txoj kab uas hla ntawm lub tog raj kheej, yog ntau tshaj li qhov ntsuas. Nws tsis muaj teeb meem yog tias qhov luaj li cas los yog kam rau ua tau cim (+-0.XX). Qhov no yog dab tsi mechanical (dimensional raug) txhais tau tias. Nws yog ib lub tswv yim zoo kom muaj nws.
Vim muaj qhov loj ntawm cov khoom siv tshuab tsim, nws yog ib qho tseem ceeb uas qhov ntau thiab tsawg yog tswj nyob rau hauv ib tug ntau yam. Cheebtsam kuj muaj geometric tolerences, uas muaj nyob txawm tias lawv tau cim los yog tsis. Lub teb chaws cov qauv qhia txog qhov tsis muaj qhov tseeb (kev ua siab ntev), thiab qee qhov kev xav tau kos duab hais tias qhov tseeb yog qhov tseem ceeb rau cov khoom siv tshuab. Qhov no yuav tsum tau muaj qee yam tsub zuj zuj. Ntxiv QQ1624392196 yog tias koj xav kom zam dhau qhov xwm txheej thiab kawm UG CNC Programming.
Cov duab kos qhia cov txheej txheem ntawm kev ua cov khoom
Cov txheej txheem tsuas yog yuav ua li cas los tsim lossis sib sau ua ke nomachining qhov. Mechanical drawings yuav tsis qhia ncaj qha txog cov txheej txheem tsim, tab sis lawv tseem muaj cov txheej txheem tseem ceeb. Yog tias ib feem tsis tuaj yeem ua tiav, nws tsis muaj txiaj ntsig los tsim nws. Tus tsim qauv yuav tsum tau xav txog yuav ua li cas ua ib feem, thiab qhov no yuav tshwm sim hauv cov duab kos.
Nto roughness ntawm cov khoom raws li qhia hauv daim duab
Qhov roughness ntawm qhov chaw txiav txim siab nws txoj kev siv thiab txwv kev ua haujlwm. Cov txheej txheem sib txawv tuaj yeem ua tiav qhov sib txawv roughness; Piv txwv li, qhov loj thiab txoj hauj lwm tolerances ntawm ib lub caij, los yog nws cov duab.
Kev kho cua sov ntawm cov khoom
Kev kho cua sov yog tsim nyog los ua kom tiav thiab xyuas kom meej tias qhov kev ua tau zoo raws li cov neeg siv khoom xav tau. Kev kho cua sov kuj muaj feem xyuam nrog cov khoom siv xaiv thiab cov cuab yeej ua haujlwm.
Khoom kho qhov chaw
Kev kho deg feem ntau hais txog cov kev xav tau. Nws kuj muaj qee qhov kev sib raug zoo rau cov khoom siv.
