Indlela yokusebenzisa i-micrometer ukukala izingxenye ezincane

Micrometer - has a eliphezulu kakhulu ukucacisa kudivayisi sokulinganisa ubukhulu izingxenye. Isetshenziselwa lapho kudingeke khona ukuze mkhosi scrupulous zobukhulu enkulu ekwakhekeni imikhiqizo. ukunemba kwayo nesilinganiso esisodwa senkulungwane a milimitha (micrometer noma Micron), futhi iphutha 2 kuphela microns 50. Kuyinto olunembile kakhulu kunangesikhathi caliper efanayo. Ukuze ubone ukuthi lezi zimiso ngokucace kakhudlwana, kufanele uyakhumbula ukuthi ukushuba unwele lomuntu imayelana 40 microns, futhi ububanzi we-erythrocyte - 7 microns.

Ukuze ufunde indlela ukusebenzisa micrometer, yabe seyaziwa ekhulwini XIX, ukuba ngqo - e 1848. Yingaleso sikhathi France unikwe igunya lokwenza umsunguli kudivayisi wokulinganisa Jean-Lui Palmeru, nakuba umbono kokusebenzisa pair isikulufa, ogxile isimiso umsebenzi we micrometer, aziwayo kusukela ngekhulu XVI. Okokuqala isikulufa pair elisetshenziswa ezindabeni zezempi (izibhamu kokudubula), bese - emithethweni topogeodesic. Kulezi zinsuku, sendlela ukusebenzisa kahle i-micrometer, eyaziwa mhlawumbe kuphela kumbuthano ewumngcingo ongoti (isib, Turner kucutshungulwa ebusweni olunembile ikakhulukazi). Kodwa sazi ukuthi singabhekana kanjani thatha izilinganiso ngosizo leli thuluzi, ngokusobala kungasho muntu, ikakhulukazi lapho esebenzelana nama-inqubo.

Umgomo we operation ye micrometer

Ingxenye esemqoka ye-micrometer kuyinto ngocingo. Wenziwe umile futhi unamathisele nalokho zonke ezinye izingxenye kudivayisi: esithendeni (ukukhonza njengephayona abutment fixed lapho enza izilinganiso), isiqu, izipikili micrometer, isigubhu kanye ratchet ngesivalo. Stem, enikezwe silinganiso fixedly exhunywe kwi-ubakaki ipayipi. Esikalini siqukethe imali kanye stem perpendicular izingozi nokushaywa unhlangothi. Ngezansi nezingozi imivimbo isicelo at ibanga 1 mm phezu Valium - 0.5 mm. Namuhla ungathola i micrometer electronic, lapho wonke amanani ziboniswa. Buhle le divayisi ukuthi Ungahlala kabusha nomunye nje touch of a inkinobho. Ukuze kuzuzwe lokhu akwenze ngokunemba okukhulu, kungcono ukwenza ngisho nangaphambi ukusetshenziswa micrometer.

Ezithathekayo kudivayisi stop nesikulufu micrometer. Ukuze clamping yayo isikhundla uyisivalo isetshenziswa. On stem sigubhu bakhathale kuyinto ebusweni oyindilinga, imivimbo yizinqamu 50 alinganayo futhi ifakwe ungene stem. Omunye micrometer kwegazi, futhi ngenxa yalokho futhi sigubhu kuholela ukufuduka kanye axis awo ngo-0.5 mm. Ngakho, enye ithuba sigubhu ngomunye phiko 1/50 0.5 mm noma 0.01 mm. Ukuze ugweme deformations izingxenye ukuze kukhawulwe ingcindezi micrometer wakhe wasebenzisa umsindo.

Indlela yokusebenzisa lapho yalinganisa micrometer

1. Into, izilinganiso okumele kulinganiswa, ibekwe phakathi isithende futhi screw micrometer. Izungezisa sigubhu lokuphotha setha eduze ngangokunokwenzeka ukuze ingxenye.
2. push ngokucophelela lokuphotha contact yayo nge ucezu elinganisiwe. Kokuqina kumele kwenziwe ebambe inyama, esisogwini ekupheleni isigubhu ujikelezisa kuphela. Lapho oxhumana Uphenyo into Ukuphela kuskrolelwa ngebhayisikili ingxenye sigubhu likhipha umsindo (chofoza). Ngemva eyesithathu chofoza Ukujikeleza kufanele wayeka.
3. Esebenzisa vernier izingxenye imitha ngamamilimitha, okuyinto funda phezu ovundlile forefinger kuthintwa, esisogwini esikalini stem.
4. Ukuze ubone ukuthi ubukhulu jikelele izingxenye alinganiswe.
5. Khipha lento sigubhu Ukujikeleza kolunye uhlangothi.

Ekuphetheni, isihloko mayelana nendlela ukusebenzisa micrometer, kufanele kuphawulwe ukuthi ukusetshenziswa kule divayisi elula kodwa eyizingqabavu akunzima kakhulu, kanye nekhono ukucacisa ubukhulu esiqondile imininingwane encane kakhulu ngezinye izikhathi kungaba usizo kakhulu.
