Dzimwe nguva, paunenge uchishanda, zvinogona kuve zvakakodzera kuti unyatsorongedza kuwanda kwechikamu chero chipi zvacho. Nokuda kwechikonzero ichi, chigadziro chepasi rose chinogadzirirwa - micrometer, iyo iyo yekunze kwechikamu chechikamu yacho yakatarwa nekakarurama kwe 2 μm (0.002 mm). Zvadaro, funga uye kupa muenzaniso wekushandisa micrometer.
Chigadzirwa chemagetsi micrometer
Kune marudzi maviri emakromrometer: magetsi uye magetsi.
Chigadzirwa chemacrometer micrometer inotanga kuvapo kwezvikamu zvinotevera:
- chitsitsinho-chigadziro chakamira;
- micrometric screw;
- Tsitsi shinda nemusango wakaiswa;
- dhiramu rakasimba rakagadziriswa pajinga;
- ratchet;
- ring ring nut;
- zviyero zviviri.
Ikoko rinotenderera mukati megwenzi rakasvibiswa demo rinenge rakamira. Nebatsiro remudonzvo, chipfupa chisina kunyatsogadziriswa. Zvinogoneka kugadzirisa chipisa chero chipi nechipi neine ring ring.
Zviyero zviviri, zvinowanikwa pajecha, zvinorongwa nenzira inotevera. Yokutanga iri pa stem uye ine mutengo wepakati we 1 mm. Ichi chikamu chakakamurwa kuita zvikamu zviviri, uye chikamu chepasi chinobvisa kubva kumusoro ne 0.5 mm. Urongwa uhwu hunoita kuti chiyero chiite. Paguramu rinotenderera kune chikamu chechipiri, icho chave nemapato makumi mashanu nemutengo we 0.01 mm.
Nzira yekushandisa micrometer zvakanaka sei?
Sezvo panguva yekushandiswa, chikamu chacho chinogogurwa pasi nguva dzose, zvinokurudzirwa kuti chimbo chacho chigadziriswe musati pese shanduro. Iyo inoitwa nenzira inotevera: chipfupa chakanyatsogadziriswa uye chinopupurirwa kuti dambudziko rakanyanyisa riri padenga rinowirirana ne zero mark on the drum. Kana musingafungi, tsananguro yakanyengedzwa nekiyi inokosha.
Kuti ushandise micrometer kuitira chinangwa chekuyera chikamu, iyo yakagadziriswa inokanganisa nekufambisa dambirwo rakatarisa iyo inenge ichingopfuura kudarika kwechikamu chacho. Chikamu chinofanira kuyerwa chinosungirirwa pakati pechitsitsinho uye chinonzi screw. Kudzivirira kukuvadzwa kune chikamu, kunonamatira nechecheche. Muchiitiko ichi, ratchet inogadzira inzwi rakasiyana kana richikonzerwa. Zvadaro simbisai mhete.
Kuti uone hukuru hwechikamu chacho, wedzera pamwe kuverengwa kwezviyero zviviri (zvikamu zviviri zveyero yekutanga pachigadziko uye chiyero chimwe pamudonzvo). Pamukamu wepamusoro wehupamhi hwehutachi, tinotarisa nhamba yekuzara mm. Kana dambudziko riri pamucheto wezasi wezera riri kurudyi, ipapo kukosha kwechikamu chepamusoro chechikwereti chakakosha kuwedzera 0.5 mm. Kukosha kunowanikwa, tinowedzera kuverenga kubva pachiyero chiri padurumu, pamwe nemutengo wekutengesa 0.01 mm.
Nzira yekushandisa micrometer zvakarurama - muenzaniso wekuyera
Chimbofunga muenzaniso wekuenzanisa kwakarurama kwehupamhi hwekuchera, uyo ane mazita masikirwo akareba 5.8 mm. Iko kunosungirirwa kunosungirirwa pakati pechigadziko chakasimbiswa uye chinonzi screw kushandisa ratchet. Uyezve, kuverengerwa kwechigadzirwa kunoitwa.
Tarisa kumusoro kwechikwereti pane stem. Kukosha kwayo kuchava 5 mm. Tinoona nzvimbo yezviitiko zvinotarisa zvemuzasi we stem scale. Ichava kurudyi, saka isu
Zvadaro, tarisa pachiyero chiri paduramu, iyo inotiratidza kukosha kwe 0.28 mm. Wedzera iyi dhigirii kusvika pachiyero chedu uye uwane 5.5 mm + 0.28 mm = 5.78 mm.
Izvo zvakaderera kubheta zvichave 5.78 mm.
Nokudaro, micrometer iyo inobatsira iwe kuyera chimwe chinhu kana chikamu nekukwirira kwakakwana. Kana iwe usina huwandu hwehukuru hwaunogona kuwana pamwe nemutongi kana caliper , une mukana wekutungamirira chiyero uchishandisa micrometer uye uwane kuenzana nekururama kwe 0.002 mm.
