Kev kam rau siab, haum, thiab kev ntsuas ntsuas hauv Part Machining
Precision nyob rau hauv ib feem machining tsis yog hais txog kev ua tiav qhov tseeb qhov ntev teev nyob rau hauv daim ntawv qhia; nws kuj muaj kev nkag siab thiab siv cov hauv paus ntsiab lus ntawm kev ua siab ntev, haum, thiab kev ntsuas. Cov tswv yim no yog qhov tseem ceeb rau kev ua kom cov khoom ua haujlwm kom raug thaum sib sau ua ke thiab tswj xyuas cov txheej txheem tsim khoom.
Tolerance
Tolerance yog qhov nyiaj pub dawb rau kev hloov pauv hauv qhov ntev ntawm ib feem. Nws yog ib qho kev lees paub tias qee qhov kev hloov pauv tsis tuaj yeem nyob hauv cov txheej txheem tsim khoom thiab tsim nyog los ua kom haum rau cov kev txwv ntawm cov khoom siv machining, cov ntaub ntawv, thiab cov txheej txheem sib dhos. Tolerances yuav raug teev rau qhov loj, zoo, orientation, thiab qhov chaw ntawm nta ntawm ib feem.
Size kam rau ua: Qhov no muaj feem xyuam rau qhov tso cai hloov pauv hauv qhov ntev ntawm ib feem, xws li nws qhov ntev, qhov dav, lossis qhov siab.
Geometric kam rau ua: Hom kev kam rau siab no qhia txog cov kev txwv rau cov duab thiab cov yam ntxwv ntawm ib feem, xws li flatness, roundness, thiab parallelism.
Positional Tolerance: Qhov kev kam rau siab no txhais tau qhov kev hloov pauv tau zoo nyob rau hauv txoj hauj lwm ntawm ib qho kev txheeb ze rau lwm qhov tshwj xeeb lossis kev siv datum.
Haum thiab nws qhov tseem ceeb
Fit yog hais txog qhov zoo ntawm ob feem mus ua ke los yog ze npaum li cas ib feem tuaj yeem sib phim rau lwm qhov. Muaj peb hom kev haum: clearance fits, cuam tshuam fits, thiab kev hloov fits.
Clearance Fit: Hom kev haum no tso cai rau qhov sib txawv ntawm ob qhov sib xyaw ua ke, uas muaj txiaj ntsig zoo rau kev sib dhos thiab kev tshem tawm tab sis yuav tsum tau siv cov roj nplua nyeem lossis kev cuam tshuam haum rau qee yam kev siv.
Interference Fit: Ib qho kev cuam tshuam haum yog thaum cov mating qhov chaw raug yuam ua ke, tsim kom muaj kev sib raug zoo. Hom kev haum no feem ntau siv rau qhov chaw uas yuav tsum tsis txhob sib cais raws li qhov xwm txheej.
Hloov Hloov Fit: Kev hloov pauv haum yog kev sib haum xeeb ntawm kev tshem tawm thiab kev cuam tshuam kev sib haum xeeb, muab kev sib haum xeeb yam tsis tas yuav tsum muaj kev sib koom ua ke.
Nkag siab txog qhov tsim nyog haum yog qhov tseem ceeb rau kev xaiv cov khoom tsim nyog, txheej txheem machining, thiab cov txheej txheem sib dhos.
Kev ntsuas hauv Machining
Kev ntsuas kev ntsuas suav nrog kev siv ntau yam cuab yeej thiab cov tswv yim los ntsuas qhov ntev thiab cov yam ntxwv ntawm ib feem. Qee cov cuab yeej ntsuas thiab cov txheej txheem suav nrog:
Calipers: Cov no yog cov cuab yeej siv ntau yam siv los ntsuas qhov ntev ntawm ib feem nrog qhov raug siab.
Micrometers: Micrometers muab qhov tseeb ntau dua li calipers, tso cai rau kev ntsuas mus rau qib micrometer.
Coordinate Measuring Machine (CMMs): CMMs yog siv rau kev ntsuas nyuaj, suav nrog cov qauv dawb-dawb thiab ntau qhov sib txawv.
Kev ntsuas: Gages yog cov cuab yeej tshwj xeeb tsim los xyuas seb ib feem puas haum raws li qhov kev cia siab. Lawv tuaj yeem yog qhov yooj yim mus / tsis mus ntsuas lossis ntau qhov nyuaj, qhia txog qhov sib txawv ntawm qhov loj me.
Laser Scanning: Cov txheej txheem qib siab no siv lasers los ntsuas qhov geometry ntawm ib feem, muab qhov tseeb 3D sawv cev ntawm cov khoom.
Xaus
Kev kam rau siab, haum, thiab kev ntsuas kev ntsuas yog ib qho tseem ceeb rau kev ua haujlwm ntawm ib feem machining. Lawv xyuas kom meej tias cov khoom raug tsim raws li cov qauv tsim nyog thiab lawv ua haujlwm kom raug thaum sib dhos. Los ntawm kev nkag siab thiab siv cov ntsiab cai no, cov tuam txhab lag luam tuaj yeem txhim kho lawv cov txheej txheem, txo cov khoom pov tseg, thiab txhim kho lawv cov khoom zoo. Raws li kev siv thev naus laus zis, qhov tseeb thiab qhov tseeb ntawm machining yuav txuas ntxiv txhim kho, nrog cov txheej txheem ntsuas tshiab thiab cov cuab yeej siv ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov nruj nruj thiab haum rau qhov xav tau rau cov khoom siv ntau dua thiab ua haujlwm siab.
