Nthawi zina, pamene mukugwira ntchito, zingakhale zofunikira kuti muzindikire kukula kwa gawo lililonse. Pachifukwa ichi, chida chapadziko lonse chimapangidwa - micrometer, yomwe mbali yakunja ya gawoyo imatsimikiziridwa molondola 2 μm (0.002 mm). Kenako, ganizirani ndi kupereka chitsanzo cha momwe mungagwiritsire ntchito micrometer.
Chipangizo cha micrometer yamagetsi
Pali mitundu iwiri ya micrometers: makina komanso zamagetsi.
Chipangizo cha micrometer yamagetsi chimakhalapo kukhalapo kwa zigawo zotsatirazi:
- chidendene - chosayima;
- chopiringizira cha micrometric;
- Tsinde lachitsamba ndi chitsamba chosungunuka;
- ngodya imakhazikika pamphuno;
- chosokoneza;
- mtedza wa mphete;
- miyeso iwiri.
The screw amayendayenda mu chitsamba chokwera cha stem stem. Mothandizidwa ndi ng'anjo, mphunoyi siidasinthika. N'zotheka kukonza chotupa pamalo aliwonse ndi mphete.
Mamba awiri, omwe ali pa chipangizo, akukonzedwa motere. Yoyamba ili pa tsinde ndipo ili ndi mtengo wogawidwa wa 1 mm. Mbali iyi imagawidwa m'magawo awiri, ndipo mbali ya pansi imachokera pamwamba ndi 0,5 mm. Ndondomekoyi imathandizira njira yoyezera. Pa dramu yoyendayenda pamakhala yachiwiri, yomwe ili ndi magawo 50 ndi mtengo wa 0.01 mm.
Kodi mungagwiritse ntchito bwanji micrometer molondola?
Popeza panthawi yogwiritsira ntchito, chiwerengerochi chimagwedezeka nthawi ndi nthawi, zimalimbikitsa kuti chidacho chizikhala chisanayambe chisanachitike. Zimayendetsedwa m'njira yotsatirayi: nkhonoyo imapotoka ndi kutsimikiziridwa kuti chiwopsezo choyendetsa pa tsinde chimagwirizana ndi zero pa drum. Ngati simudziwa, tsinde laphatikizidwa ndi makiyi apadera.
Kuti mugwiritse ntchito micrometer kuti muyese gawoli, ziphuphu zimapotozedwa ndi kuyendetsa dambali mtunda umene umadutsa pang'ono kukula kwa gawolo. Gawo loti liyezedwe limagwedezeka pakati pa chidendene ndi chifuwa. Pofuna kuteteza kuwonongeka kwa gawoli, zimaphatikizidwa ndi ngongole. Pankhaniyi, phokosoli limapanga phokoso lapadera pamene likuyambitsa. Kenaka imitsani mtedza wa mphete.
Kuti mudziwe kukula kwa gawolo, onjezerani kuwerenga kwa miyeso iwiri (magawo awiri a chiyeso choyamba pa tsinde ndi mlingo umodzi pa drum). Pamwamba pa msinkhu wa tsinde, timayang'ana chiwerengero chazomwe mm. Ngati chiwopsezo pamunsi mwa tsinde ndilo kulondola, ndiye kuti phindu la gawo la pamwamba ndilofunika kuwonjezera 0,5 mm. Kuchokera phindu, tikuwonjezera kuwerengera kuchokera muyezo pa drum, ndi mtengo wogawa 0.01 mm.
Momwe mungagwiritsire ntchito micrometer molondola - chitsanzo cha muyeso
Talingalirani chitsanzo cha kuyeza molondola kwa kukula kwake, omwe kukula kwake ndi 5.8 mm. Chombocho chimagwedezeka pakati pa malo osayimika ndi zokopa pogwiritsa ntchito makoswe. Komanso, kuwerenga kwa chipangizochi kumapangidwa.
Yang'anani pamwamba pa msinkhu pa tsinde. Phindu lake lidzakhala 5 mm. Timazindikira malo omwe amawoneka oopsa a mbali ya pansi ya tsinde. Zidzakhala kumanja, kotero ife
Kenaka, yang'anirani kukula kwa drum, yomwe imatiwonetsera mtengo wa 0.28 mm. Onjezerani detayi pamtunda wa tsinde ndikupeza 5.5 mm + 0.28 mm = 5.78 mm.
Mzere wokwanira wa kubowola udzakhala 5.78 mm.
Kotero, chipangizo cha micrometer chidzakuthandizani kuti muyese chinthu kapena gawo ndi chidziwitso chapamwamba. Ngati mulibe kukula kokwanira komwe mungapeze ndi wolamulira kapena caliper , muli ndi mwayi wochita muyeso pogwiritsa ntchito micrometer ndikupeza kutalika kwa 0.002 mm.
