Ngamanye amaxesha, xa kusebenza, kunokuba kuyimfuneko ukuchonga ngokuchanekileyo ubukhulu becala nayiphi na inxenye. Kule njongo, ithuluzi lokuphela jikelele lenzelwe - i-micrometer, apho ububanzi obungaphandle bendawo inqunywe ngokuchaneka kwe-2 μm (0.002 mm). Emva koko, cinga kwaye unike umzekelo wendlela yokusebenzisa i-micrometer.
I sixhobo se micrometer yomatshini
Kukho ezimbini iindidi ze-micrometer: umatshini kunye nombane.
I sixhobo se-micrometer yomatshini sithatha ubukho beendawo ezilandelayo:
- isitima esinqamlekileyo;
- isibuko se micrometric;
- Isitshixo sentshukumo ehlathini;
- idrama egxininiswe ngokuqinileyo kwisikiti;
- i-ratchet;
- nut nut;
- izikali ezimbini.
Isikratshi sijikeleza kwisiqithi esityiweyo sesigxina. Ngokuncedwa kwidrama, isiqwenga singenakulungiswa. Kunokwenzeka ukulungisa isihlunu kuyo nayiphi na isikhundla nge nut nut.
Izikali ezimbini, ezifumaneka kwisixhobo, zilungiselelwe ngolu hlobo lulandelayo. Iyokuqala isezantsi kwaye inexabiso lokwahlukana kwe-1 mm. Eli nqanaba lihlulwe libe ngamacandelo amabini, kwaye inxalenye engezantsi icatshulwe phezulu ukusuka kwi-0.5 mm. Eli lungiselelo liququzelela inkqubo yokulinganisa. Kwi-drum ejikelezayo kukho isixa sesibini, esinamaqela ahlukileyo ngama-0.01 mm.
Indlela yokusebenzisa i-micrometer ngokuchanekileyo?
Ukususela ngexesha lokusetyenziswa, isixa sichithwa ngamaxesha, kuyacetyiswa ukuba isixhobo sithengiswe phambi kwesicelo ngasinye. Yenziwa ngendlela elandelayo: i-screw igxile ngokupheleleyo kwaye iqinisekiswe ukuba umngcipheko ongqambileyo kwisigxina uhambelana nomgca we-zero kwisigubhu. Ngaphandle kokungahambi kakuhle, isiqu siphendulelwe ngundoqo ekhethekileyo.
Ukuze usebenzise i-micrometer ngenjongo yokulinganisa inxalenye, isiqwenga siphutha ngokujikeleza isigubhu umgama oya kudlula ubuncinane bendawo. Inxalenye ekufuneka ilinganiselwe ifakwe phakathi kwesithende kunye nesihlunu. Ukuthintela umonakalo kwinqanaba, iphoswe nge-ratchet. Kule meko, i-ratchet ivelisa isandi esahlukileyo xa ikhutshwe. Emva koko, qinisa i nut nut.
Ukufumanisa ubungakanani benxalenye, fakela ndawonye ukufundwa kwezikali ezimbini (iindawo ezibini zesilinganiso sokuqala kwisiqu kunye nomlinganiselo omnye kwisigubhu). Kwinqanaba eliphezulu le-stem, sibheka kwinani le-mm epheleleyo. Ukuba umngcipheko kwicandelo elingaphantsi kwinqanaba le-stem likunene, ngoko ke kwixabiso le-nxalenye ephezulu yesikali kuyimfuneko ukufaka i-0.5 mm. Kuxabiso elifunyenweyo, songeza ukufundwa kwinqanaba kwisigubhu, kunye nexabiso lentlukwano 0.01 mm.
Indlela yokusebenzisa i-micrometer ngokuchanekileyo-umzekelo wesilinganiselo
Khawucinge ngomzekelo wendlela echanekileyo ngayo ububanzi bebhola, obunomlinganiselo ongama-5.8 mm. I-drill iyabhalwa phakathi kwe-stop stop and screw usebenzisa i-ratchet. Ngaphezulu, ukufundwa kwesixhobo kwenziwa.
Khangela phezulu kwinqanaba kwi-stem. Ixabiso layo liya kuba ngu-5 mm. Sinqumanisa isikhundla seengozi ezibonakalayo zeengcambu eziphantsi. Kuya kuba ngakwesokudla, ngoko
Emva koko, jonga kwinqanaba kwisigubhu, esisibonisa ubunani be-0.28 mm. Yongeza le nkcukacha kwizinga le-stem uze ufumane 5.5 mm + 0.28 mm = 5.78 mm.
Ubuninzi obubanzi be-drill iya kuba ngu-5.78 mm.
Ngaloo ndlela, i-micrometer yesixhobo izokukunceda ukuba ulinganise into okanye inxalenye ngokuchaneka ngokuchanekileyo. Ukuba awunalo ngokwaneleyo ubukhulu obungasifumana nomlawuli okanye umgcini , unethuba lokuqhuba umlinganiselo usebenzisa i-micrometer kwaye ufumane ubungakanani ngokuchaneka kwe-0.002 mm.
