How kushandisa micrometer kuyera maduku zvikamu

Micrometer - ane zvikuru zvakarurama mudziyo kuti kuyera kukura zvikamu. Rinoshandiswa apo zvakakodzera kuti vatevedzere kuchengetwa miganhu iri kugadzirwa mishonga. Its kuyerwa rakarurama rimwe kuzviuru ane millimeter (micrometer kana micron), uye kukanganisa kuri 2 chete 50 microns. Zviri zvikuru zvakarurama pane imwe caliper. Kuti ufungidzire tsika izvi zvakajeka, zvinofanira kudzoswa kuti pakukora sebvudzi romunhu anenge 40 microns, uye dhayamita of erythrocyte - 7 microns.

Kudzidza kushandisa micrometer, yakasvika pakuzivikanwa ari XIX remakore, kuti munoreva - muna 1848. Panguva iyoyo France akapiwa imwe bvumidzwa kuti tambo mudziyo muvambi Jean-Lui Palmeru, kunyange zvazvo pfungwa uchishandisa sikuruu peya, iyo yakavakirwa panheyo basa micrometer, kuvazivisa kubvira XVI remakore. First sikuruwa vaviri kushandiswa zvehondo (nokuridzira pfuti), uye ipapo - mune topogeodesic zviridzwa. Mazuva ano, sei zvakakodzera kushandisa micrometer, rinozivikanwa zvichida chete rakamanikana yakaurungana unyanzvi (semuenzaniso, Turner processing kunyanya yakarurama pamusoro). Asi kuziva sei kutora kuyerwa tichibatsirwa chokushandisa ichi, pachena asingaiti kurwadzisa munhu, kunyanya pakubata magadzirirwo.

Nheyo kushanda ane micrometer

The chikuru Chikamu micrometer chinhu kiramba. Chinoitwa mira uye zvakabatanidzwa nayo dzimwe dzose mudziyo: chitsitsinho (kushumira somushumiri wakaiswa abutment kana kuita kuyerwa), hunde, mumwe micrometer sikuruu, kuti dhiramu uye ratchet chimiso. Hunde, iro pakafunuka iri fixedly zvakabatana nomutopota chikomboredzo. The chikero vanosanganisira rakachengetedzwa achitevedza hunde perpendicular kune ngozi uye shamhu. Below Ngozi Kurohwa aishanda ari chinhambwe 1 mm uye pamusoro Valium - 0.5 mm. Mazuvano unogona kuwana wemagetsi micrometer, apo tsika zvose anonyorwa. Kunakisa mudziyo uyu kuti zvinogona kugara itangezve pamwe chete kubatwa ane bhatani. Kuti vabudirire zvikuru zvakarurama, zviri nani kuita kunyange pamberi kushandisa micrometer.

Chinjwa vanorega mudziyo uri micrometer sikuruu. Nokuti clamping yaro panzvimbo yacho chimiso inoshandiswa. On hunde Worn Drum chinhu conical pamusoro, Kurohwa muzvikamu 50 vakaenzana kumativi uye akaiswa angonanga hunde. Mumwe micrometer kuparadzirwa, uye somugumisiro vo dhiramu kunotungamirira kuti misha pamwe wayo akabatana ne 0.5 mm. Saka, mumwe kwezana dhiramu nomumwe weboka iri 1/50 pakati 0.5 mm kana 0.01 mm. Kuti tidzivise deformations zvikamu kushomeka kumanikidza kwake micrometer akashandisa rira.

How kushandisa kana kuyera munhu micrometer

1. Item, kukura zvinofanira kuyerwa, anoiswa pakati chitsitsinho uye micrometer sikuruu. Rotating Drum chokurukisa wakaiswa sezvo pedyo sezvinobvira kuti chikamu.
2. Nyatsoongorora kusunda chokurukisa kuti kubatana dzaro chakayerwa chimedu. Tightening zvinofanira kuitwa chete vakabata nyama, riri pamusoro kuguma kutenderera dhiramu. Kana vachiongorora contactsGoogle kuguma chinhu ari scrolled achitevedza Drum mugove inongorira ruzha (watinya). Mushure wechitatu tinya kutenderera anofanira kumiswa.
3. Kuburikidza vernier kuti mita zvikamu millimeters, riri verenga pamusoro chinjikira forefinger unobatwa, riri pamusoro rapanzvimbo hunde.
4. Kuti uone zvinonyatsorehwa ukuru akayera zvikamu.
5. Tisunungurirei chinhu Drum kutenderera negwara risiri.

Mukupedzisira, nyaya sei kushandisa micrometer, zvinofanira kucherechedzwa kuti kushandiswa nyore asi akasimba mudziyo ichi hachisi kuoma, uye dzimwe nguva kukwanisa kuona chaiyo kukura kwazvo zvidiki zvinogona kubatsira chaizvo.
