Mukuyedzwa kwemazuva ese, mukuwedzera kune echokwadi ma paramita emidziyo pachayo, wakambofunga nezve mabatiro ekuyera saizi yemuenzaniso pamhedzisiro yebvunzo? Ichi chinyorwa chichabatanidza zviyero uye chaiwo makesi kupa mamwe mazano pamusoro pechiyero chekukura kwezvimwe zvinhu zvakajairika.
1.Ko kukanganisa pakuyera saizi yemuenzaniso kunokanganisa zvakadii mhinduro dzebvunzo?
Chekutanga, kukura kwakadii kukanganisa kwakakonzerwa nekukanganisa. Semuenzaniso, kune imwechete yekukanganisa 0.1mm, yehukuru hwe10mm, iko kukanganisa ndeye 1%, uye yehukuru 1mm, iko kukanganisa kuri 10%;
Chechipiri, kuti saizi ine simba rakawanda sei pamhedzisiro. Kune iyo yekukotama yekuverenga formula, hupamhi hune yekutanga-kurongeka mhedzisiro pane mhedzisiro, nepo ukobvu kune yechipiri-kurongeka mhedzisiro pane mhedzisiro. Kana kukanganisa kwakafanana kwakafanana, kukora kune simba guru pane chigumisiro.
Semuyenzaniso, hupamhi hwakajairwa uye ukobvu hweiyo bending test specimen ndeye 10mm uye 4mm zvakateerana, uye kubhenda modulus i8956MPa. Kana iyo chaiyo saizi yemuenzaniso yaiswa, hupamhi uye ukobvu iri 9.90mm uye 3.90mm zvakateerana, iyo yekukotama modulus inova 9741MPa, kuwedzera kweinoda kusvika 9%.
2.Ndeipi mashandiro emidziyo yakajairwa yekuyera saizi?
Midziyo yekuyeresa yakajairika parizvino inonyanya kukoshesa micrometers, calipers, makuro geji, nezvimwe.
Huwandu hweakajairwa mamicrometer kazhinji haapfuuri 30mm, chigadziriso chiri 1μm, uye iyo yakanyanya kukanganisa kukanganisa ndeye ±(2~4)μm. Kugadziriswa kwepamusoro-chaiyo micrometers inogona kusvika 0.1μm, uye iyo yakanyanya kuratidza kukanganisa ndeye ± 0.5μm.
Iyo micrometer ine yakavakirwa-mukati yekuyera simba kukosha kwesimba, uye chiyero chega chega chinogona kuwana mugumisiro wekuyera pasi pemamiriro ekugara akabatana nechisimba, iyo inokodzera kuyera kuyerwa kwezvinhu zvakaoma.
Kuyeresa kwakasiyana-siyana kwechinyakare caliper kazhinji haapfuure 300mm, ine resolution ye0.01mm uye yakakura inoratidza kukanganisa kweinokwana ± 0.02~0.05mm. Mamwe macaliper akakura anogona kusvika pachiyero che1000mm, asi kukanganisa kuchawedzerawo.
Iko kukosha kwesimba rekumanikidza kwecaliper kunoenderana nekushanda kwemushandisi. Migumisiro yekuyera yemunhu mumwechete inowanzogadzikana, uye pachava nemusiyano pakati pemigumisiro yekuyera yevanhu vakasiyana. Inokodzera kuyerwa kwedimensional yezvinhu zvakaoma uye kuyerwa kwedimensional yezvimwe zvinhu zvakapfava zvakakura.
Kufamba, kurongeka, uye kugadziriswa kwegeji yakakora zvinowanzofanana neayo emicrometer. Izvi zvigadziri zvinopawo kudzvinyirirwa nguva dzose, asi kudzvinyirira kunogona kugadziriswa nekushandura mutoro pamusoro. Kazhinji, michina iyi yakakodzera kuyera zvinhu zvinyoro.
3.Ungasarudza sei yakakodzera saizi yekuyera michina?
Kiyi pakusarudza dimensional yekuyeresa midziyo ndeyekuona kuti anomiririra uye anodzokororwa zvakanyanya bvunzo mhinduro inogona kuwanikwa. Chinhu chekutanga chatinoda kufunga nezvacho ndiwo maparamita akakosha: huwandu uye huchokwadi. Uye zvakare, inowanzoshandiswa dimensional yekuyeresa michina yakadai semamicrometer uye macalipers midziyo yekuyeresa. Kune mamwe maumbirwo akakosha kana masampula akapfava, isu tinofanirawo kufunga nezve pesvedzero yechimiro cheprobe uye simba rekubata. Zvakadaro, mipimo mizhinji yakaisa pamberi inoenderana zvinodiwa pamidziyo yekuyeresa mativi: ISO 16012:2015 inotaura kuti majekiseni akaumbwa ma splines, mamicrometer kana ma micrometer ukobvu geji anogona kushandiswa kuyera hupamhi nekukora kwemajekiseni akaumbwa emuenzaniso; yezviyero zvemuchina, calipers uye isiri-yekubata yekuyeresa michina inogona kushandiswa zvakare. Nekuda kwechiyero chekuyera mhedzisiro ye<10mm, iko kurongeka kunofanirwa kunge kuri mukati me ± 0.02mm, uye kune mibairo yekuyera mibairo ye ≥10mm, iyo chaiyo inodiwa i ± 0.1mm. GB/T 6342 inotara nzira yekuyera yemhando yemapurasitiki efuro uye rabha. Kune mamwe masampuli, micrometers uye calipers zvinotenderwa, asi kushandiswa kwema micrometers uye calipers kwakanyatso kurongedzerwa kuti sampuli irege kuiswa pasi pemasimba makuru, zvichiita kuti pave nemigumisiro yekuyera isina kururama. Pamusoro pezvo, kune masampuli ane ukobvu husingasviki 10mm, chiyero chinokurudzirawo kushandiswa kwemicrometer, asi ine zvinodiwa zvakasimba zvekunetseka kwekusangana, iyo 100±10Pa.
GB/T 2941 inotsanangura iyo dimensional yekuyera nzira yemasampuli erabha. Izvo zvakakosha kuti ticherechedze kuti kune masamples ane ukobvu husingasviki 30mm, chiyero chinotsanangura kuti chimiro cheprobe idenderedzwa flat pressure tsoka ine dhayamita ye2mm ~ 10mm. Pamasampuli ane kuoma kwe ≥35 IRHD, mutoro wakaiswa i22±5kPa, uye kune masampuli ane kuoma kuri pasi pe35 IRHD, mutoro wakaiswa i10±2kPa.
4.Ndeipi midziyo yekuyera inogona kukurudzirwa kune zvimwe zvinhu zvakajairika?
A. Kune epurasitiki tensile mienzaniso, zvinokurudzirwa kushandisa micrometer kuyera upamhi uye ukobvu;
B. Kune zvienzaniso zvinokanganisa, micrometer kana geji yakakora ine resolution ye1μm inogona kushandiswa kuyerwa, asi radius yearc iri pazasi pe probe haifanire kudarika 0.10mm;
C. Pamasampuli emufirimu, geji yekukora ine sarudzo iri nani kupfuura 1μm inokurudzirwa kuyera ukobvu;
D. Kune mienzaniso yerubber tensile, geji yehupamhi inokurudzirwa kuyera ukuru, asi kutarisa kunofanira kubhadharwa kune nzvimbo yekuongorora uye mutoro;
E. Kune dzakatetepa furo zvinhu, yakatsaurirwa geji yeukobvu inokurudzirwa kuyera ukobvu.
5. Pamusoro pekusarudza midziyo, ndedzipi dzimwe pfungwa dzinofanira kuitwa pakuyera zviyero?
Nzvimbo yekuyera yezvimwe zvienzaniso inofanirwa kutariswa kuti inomiririra saizi chaiyo yemuenzaniso.
Semuenzaniso, kune jekiseni rakaumbwa rakakomberedzwa splines, pachave negwaro angle isingapfuure 1 ° padivi pe spline, saka kukanganisa pakati pehupamhi uye hudiki hupamhi hutsika hunogona kusvika 0.14mm.
Uye zvakare, majekiseni akaumbwa ekuenzanisa achave nekupisa kwekupisa, uye pachave nemusiyano wakakura pakati pekuyera pakati uye pamucheto wemuenzaniso, saka zviyero zvakakodzera zvinotsanangurawo nzvimbo yekuyera. Semuenzaniso, ISO 178 inoda kuti nzvimbo yekuyera yehupamhi hwemuenzaniso i ± 0.5mm kubva pahupamhi hwepakati, uye nzvimbo yekuyera ukobvu i± 3.25mm kubva pahupamhi hwepakati.
Pamusoro pekuona kuti zviyero zvakayerwa nemazvo, kutarisirwa kunofanirwa kutorwa kudzivirira kukanganisa kunokonzerwa nekukanganisa kwevanhu.
