Kodi kugwiritsa ntchito micrometer kuyeza mbali yaing'ono

Micrometer - ali mkulu kwambiri mwatsatanetsatane chipangizo kuona kukula kwa mbali. Izo ntchito kumene zofunika scrupulous mwambo wa miyeso mu kupanga mankhwala. molondola muyeso wa masauzande imodzi ya millimeter (micrometer kapena micron), ndi zolakwa ndi 2 okha 50 microns. Ndi zambiri zolondola koposa pa caliper chomwecho. Udzakhalire mfundo izi momveka bwino, tiyenera kukumbukira kuti makulidwe a tsitsi la munthu ndi 40 microns, ndi awiri a erythrocyte wa - 7 microns.

Kuphunzira mmene ntchito micrometer, inali kudziŵika m'zaka za m'ma XIX, kukhala enieni - mu 1848. Zinali ndiye kuti France wapatsidwa ndi setifiketi ya chingwe chipangizo zatsopano Jean-Lui Palmeru, ngakhale lingaliro la ntchito awiri wononga, ozikidwa pa mfundo za ntchito ya micrometer ndi, ndizodziwikiratu kuyambira m'zaka za m'ma XVI. awiri oyamba wononga ntchito mu zochitika ankhondo (kuomba mfuti), ndiyeno - mu zida topogeodesic. masiku awa, pa momwe ntchito bwino ndi micrometer, odziwika mwina ku bwalo yopapatiza akatswiri (mwachitsanzo, Turner processing pamwamba makamaka zolondola). Koma kudziŵa mmene miyezo mothandizidwa ndi chida ichi, mwachionekere sakuwupweteka aliyense, makamaka polimbana ndi njira ya.

Mfundo ntchito micrometer ndi

Mbali yaikulu ya micrometer ndi achepetsa. Linapangidwa n'kupuma ndi Ufumuyo thereto Ziwalo zina zonse chipangizo: chidendene (akutumikira monga abutment atathana pamene akuchita miyezo), tsinde, ndi micrometer wononga, ng'oma ndi ratchet pakamwapo. Tsinde, amene lonse lapansi fixedly olumikizidwa kwa chitoliro bulaketi. The lonse imakhala waikamo pamodzi tsinde perpendicular kwa kuopsa ndi zikwapu. Pansipa mavuto zikwapu ntchito pa mtunda wa 1 mamilimita ndi pa Valium - 0.5 mm. Masiku ano mukhoza kupeza micrometer pakompyuta, kumene mfundo zonse anasonyeza. The ntchito chipangizo izi kuti nthaŵi zonse bwererani ndi kukhudza imodzi yokha ya batani. Pofuna kukwaniritsa lolondola kwambiri, ndi bwino kuchita ngakhale patsogolo ntchito micrometer a.

Makina amasiya chipangizo ndi micrometer wononga. Pakuti clamping ake pamalo wokambirana ntchito. Tsinde ankavala ng'oma ndi conical pamwamba, zikwapu mbali 50 wofanana ndi anaikapo kumtunda tsinde la. Mmodzi micrometer kufalitsidwa, ndipo potsatira komanso ng'oma akutitsogolera kuti kusamutsidwa pamodzi nguli ndi mamilimita 0.5. Choncho, munthu kwa ng'oma ndi Chigawo chimodzi ndi 1/50 wa mamilimita 0.5 kapena 0.01 mm. Kupewa deformations mbali kuchepetsa kuthamanga pa micrometer iye anagwiritsa ntchito kulira.

Kodi ntchito pamene kuyeza ndi micrometer

1. Katunduyo, miyeso ya zimene ziyenera anayeza, aikidwa pakati pa chidendene ndi micrometer wononga. Onsewo ng'oma spindle anapereka pafupi zotheka mbali.
2. Mosamala kulikankhira spindle kucheza ake ndi chidutswa mpandawo. Kumangika ziyenera kuchitika kokha atanyamula nyama ili pa mapeto a ng'oma onsewo. Pamene ojambula kafukufuku mapeto item ndi scrolled pamodzi ng'oma gawo limatulutsa phokoso (pitani). Pambuyo wachitatu dinani kasinthasintha ayenera kusiyidwa.
3. Kudzera mwa vernier ziwalo mita mu millimeters, amene kuwerenga pa yopingasa chikunena mkombaphala, yomwe ili pa sikelo ya tsinde la.
4. Pofuna kudziwa kukula wonse wa mbali anayeza.
5. Kumasula katunduyo ng'oma kasinthasintha zosiyana.

Pomaliza, nkhani za mmene ntchito micrometer, tisaiwale kuti ntchito chipangizo osavuta kumva koma wangwiro si wovuta, ndi luso kudziwa kukula lenileni la zinthu zazing'ono kwambiri zikhoza kukhala zothandiza kwambiri.
