Indlela yokusebenzisa i micrometer ukulinganisa namalungu amancinane

Micrometer - has isixhobo ngqo eliphezulu kakhulu zokulinganisa ubungakanani iinxalenye. Isetyenziswa apho kuyimfuneko ukuze kugcinwe zihlabane nomnye ekwenziweni kweemveliso. Ukuchaneka kwayo kumetwa omnye sewaka ndlela (micrometer okanye micron), kwaye Lemposiso 2 ukuya microns-50 kuphela. Kuyinto achaneke ngaphezu kwi imbi efanayo. Ukuze nomfanekiso ngokucacileyo ngakumbi ezi amaxabiso, kufuneka ukhumbula ukuba Ebubanzini nonwele lomntu obumalunga 40 microns, yaye ububanzi we erythrocyte - 7 microns.

Ukuze ufunde ukusebenzisa indlela micrometer, oko kwazeka ngenkulungwane XIX, ukuba ngqo - ngo 1848. Kungelo xesha awathi France unikwe igunya umenzi isixhobo sokulinganisa Jean-Lui Palmeru, nangona ingcamango usebenzisa ipere esijijwayo, olusekelwe kumgaqo umsebenzi micrometer, owaziwa ukususela kwinkulungwane XVI. iqhosha lemenyu bokuqala ezisetyenziswa kwimicimbi zomkhosi (nemipu ukudubula), yaye emva koko - kwizixhobo topogeodesic. Kule mihla, ngendlela yokusebenzisa kakuhle i micrometer, eyaziwa mhlawumbi kuphela isangqa elimxinwa leengcali (umzekelo, Turner lokuqhubeka umphezulu ingakumbi echanekileyo). Kodwa ukwazi njani ukuba bathathe imilinganiselo ngoncedo esi sixhobo, ngokucacileyo ayikho buhlungu nabani na, ingakumbi ukujongana buciko.

Umgaqo ekusebenzeni micrometer

Inxalenye engundoqo micrometer yi kwesibambi. Oku kwenziwa zokubhala kwaye ziqhotyoshelwe kuso zonke ezinye iindawo ifowuni: isithende (ukukhonza njenge abutment esisigxina xa ukwenza imilinganiselo), isiqu, ngesilungelelanisi micrometer, igubu kunye ratchet isivalo. Esiqwini, apho i asakhasayo fixedly eqhagamshelwe isibiyeli kumbhobho. Isikali iqulathe sibekwe ecaleni izikhondo aa Incopho imingcipheko kunye kwamalungu omzimba. Ngezantsi umngcipheko imivimbo isicelo kumgama 1 mm naphezu Valium - 0.5 mm. Kwezintsuku uyakwazi ukufumana i micrometer elektroniki, apho onke amaxabiso elibonisiweyo. Abaxhamla kule divaysi kukuba usenokuphinda kwakhona nge touch nje omnye iqhosha. Ukwenzela ukuba kufikelelwe ukuchana enkulu, kungcono ukwenza phambi kokusetyenziswa micrometer.

isixhobo ezinokususwa stop ngesilungelelanisi micrometer. Kuba nokubotshwa zalo kusetyenziswe ngesiciko. On stem Igubu eligugileyo bungumphezulu etsobhileyo, ukufa kwamalungu yahlulwe 50 alinganayo kwaye ifakwe kwi esiqwini. Enye ukujikeleza micrometer, yaye ngenxa yoko ke igubu kukhokelela ukuhamba kunye axis zawo 0.5 mm. Ngenxa yoko, omnye ekujikeni igubu kwiyantlukawano mnye 1/50 ka-0.5 mm okanye 0,01 mm. Ukuze siphephe deformations iindawo ukunciphisa uxinzelelo micrometer wakhe wasebenzisa Urhashaza.

Indlela yokusebenzisa xa yalinganisa micrometer

1. Into, imilinganiselo ekufuneka ingenakulinganiswa, ibekwe phakathi isithende kunye Screw micrometer. Batshintshana Igubu othini ebekwe kufutshane kangangoko kule ndawo.
2. Ngocoselelo tyhala edibanise ukuba ukudibana kwawo negophe elilinganisiweyo. Ukuqinisa kufuneka kwenziwe ebambelele kuphela ezidliwayo, ibekwe kwi ekupheleni kwigubu olujikelezayo. Xa abafowunelwa uphenyo nto isiphelo scrolled ecaleni isahlulo igubu nekhupha isandi (click). Emva yesithathu nqakraza ukujikeleza kufuneka imiswe.
3. Esebenzisa le vernier kwiindawo kwimitha iimillimitha, efundwayo kwi bemchukumisa Uvalo tye, ibekwe kwi kwisikali izikhondo.
4. Ukuze ubone inani labantu ngokubanzi iinxalenye kulinganiswa.
5. Bakhulule into Igubu ukujikeleza kwicala elahlukileyo.

Elokuqukumbela, eli nqaku malunga ukusebenzisa indlela micrometer, kufanele kuqatshelwe ukuba ukusetyenziswa kwale isixhobo elula kodwa robust Akukho nzima kakhulu, kwaye ukukwazi ukufumanisa ubungakanani ngqo iinkcukacha ezincinane kakhulu maxa wambi kuba luncedo kakhulu.
