Mukuyedza kwezuva nezuva, pamusoro pematanho ekururama kwemuchina wacho, wakambofunga here nezvemhedzisiro yekuyerwa kwesampuro pamhedzisiro yebvunzo? Chinyorwa chino chichabatanidza zviyero nezvimwe zviitiko kuti zvipe mamwe mazano pakuyerwa kwesaizi yezvimwe zvinhu zvakajairika.

1. Kukanganisa pakuyera saizi yemuenzaniso kunokanganisa zvakadii mhedzisiro yebvunzo?

Kutanga, kuti kukanganisa kwakakonzerwa nekukanganisa kwakakura sei. Semuenzaniso, kune kukanganisa kwakafanana kwe0.1mm, kune saizi ye10mm, kukanganisa i1%, uye kune saizi ye1mm, kukanganisa i10%;

Chechipiri, saizi yacho ine simba rakadii pamhedzisiro. Pafomura yekuverenga simba rekukotama, upamhi hune mhedzisiro yekutanga pamhedzisiro, nepo ukobvu hune mhedzisiro yechipiri pamhedzisiro. Kana chikanganiso chakafanana, ukobvu hune simba guru pamhedzisiro.
Semuenzaniso, upamhi hwakajairika uye ukobvu hwemuenzaniso wekuyedza wekukotama i10mm ne4mm zvichiteerana, uye modulus yekukotama i8956MPa. Kana saizi chaiyo yemuenzaniso yaiswa, upamhi uye ukobvu i9.90mm ne3.90mm zvichiteerana, modulus yekukotama inova 9741MPa, kuwedzera kweinenge 9%.

2. Chii chiri kushanda kwemidziyo yekuyera saizi yemuenzaniso wakajairika?

Midziyo yekuyera mativi inonyanya kushandiswa pari zvino inonyanya kushandiswa nema micrometer, ma caliper, ma thickness gauges, nezvimwewo.

Rudzi rwema micrometer akajairwa harupfuure 30mm, resolution yacho i1μm, uye chikanganiso chikuru chechiratidzo chingangoita ±(2~4)μm. Resolution yema micrometers ane kunyatsojeka inogona kusvika 0.1μm, uye chikanganiso chikuru chechiratidzo i±0.5μm.

Iyo micrometer ine simba rekuyera risingaperi rakavakirwa mukati, uye chiyero chega chega chinogona kuwana mhedzisiro yekuyera pasi pemamiriro esimba rekubata risingaperi, iro rakakodzera kuyerwa kwehukuru hwezvinhu zvakaoma.

Kuyera kwe caliper yakajairika kazhinji hakupfuuri 300mm, ine resolution ye 0.01mm uye chiratidzo chikuru chekukanganisa chingangoita ±0.02~0.05mm. Mamwe ma caliper makuru anogona kusvika pakuyera kwe1000mm, asi kukanganisa kuchawedzerawo.

Kukosha kwesimba rekusunga remuchina we caliper kunoenderana nekushanda kwemushandisi. Mhedzisiro yekuyera yemunhu mumwe chete inowanzova yakagadzikana, uye pachava nemusiyano wakati pakati pemhedzisiro yekuyera yevanhu vakasiyana. Yakakodzera kuyerwa kwehukuru hwezvinhu zvakaoma uye kuyerwa kwehukuru hwezvimwe zvinhu zvakapfava zvakakura.

Kufamba, kururama, uye kugadziriswa kwegeji yekukora zvinowanzofanana nekwe micrometer. Midziyo iyi inopawo kumanikidzwa kunogara kuripo, asi kumanikidzwa kunogona kugadziriswa nekuchinja mutoro uri pamusoro. Kazhinji, michina iyi yakakodzera kuyera zvinhu zvakapfava.

3. Ungasarudza sei michina yekuyera saizi yakakodzera?

Chinhu chikuru pakusarudza michina yekuyera mativi ndechekuona kuti mhinduro dzebvunzo dzinomiririra uye dzinodzokororwa zvikuru dzinogona kuwanikwa. Chinhu chekutanga chatinofanira kufunga nezvacho parameters huru: huwandu uye kururama. Pamusoro pezvo, michina yekuyera mativi inoshandiswa zvakanyanya senge ma micrometer nema caliper ndiyo michina yekuyera yekubata. Kune mamwe maumbirwo akakosha kana sampuro dzakapfava, tinofanirawo kufunga nezvesimba reprobe uye simba rekubata. Kutaura zvazviri, mitemo yakawanda yakaisa zvinodiwa zvinoenderana nemidziyo yekuyera mativi: ISO 16012:2015 inotaura kuti kune injection molded splines, ma micrometer kana ma micrometer thickness gauges anogona kushandiswa kuyera upamhi uye ukobvu hweinjection molded sampuli; kune machined sampuli, ma caliper uye michina yekuyera isina kubata inogona kushandiswawo. Kune divi rekuyera mhedzisiro ye <10mm, kururama kunofanirwa kunge kuri mukati me ±0.02mm, uye kune divi rekuyera mhedzisiro ye ≥10mm, kudikanwa kwekururamisa i ±0.1mm. GB/T 6342 inotaura nzira yekuyera mativi emapurasitiki efoam nerabha. Kune mimwe mienzaniso, ma micrometer nema caliper zvinotenderwa, asi kushandiswa kwema micrometer nema caliper kwakanyatsorongerwa kudzivirira kuti sampuro isapinzwe nesimba guru, zvichikonzera mhedzisiro isiriyo yekuyera. Pamusoro pezvo, kune sampuli dzine ukobvu husingasviki 10mm, standard inokurudzirawo kushandiswa kwe micrometer, asi ine zvinodiwa zvakasimba zvekusangana nechinhu, izvo zviri 100±10Pa.

GB/T 2941 inotsanangura nzira yekuyera mativi emasampuli erabha. Zvakakosha kuziva kuti kune masampule ane ukobvu husingasviki 30mm, chiyero chinotaura kuti chimiro cheprobe idenderedzwa rakatsetseka rakatsetseka rine dhayamita ye2mm ~ 10mm. Kune masampule ane kuomarara kwe ≥35 IRHD, mutoro wakaiswa i22±5kPa, uye kune masampule ane kuomarara kusingasviki 35 IRHD, mutoro wakaiswa i10±2kPa.

4. Ndezvipi zvishandiso zvekuyera zvinogona kukurudzirwa kune zvimwe zvinhu zvakajairika?

A. Pamhando dzepurasitiki dzinodhonza, zvinokurudzirwa kushandisa micrometer kuyera upamhi neukobvu;

B. Kune sampuli dze "notched impact", micrometer kana "thickness gauge" ine resolution ye1μm inogona kushandiswa kuyera, asi radius ye "arc" iri pasi pe "probe" haifanirwe kudarika 0.10mm;

C. Kune mienzaniso yefirimu, gauge yeukobvu ine resolution iri nani kupfuura 1μm inokurudzirwa kuyera ukobvu;

D. Kune sampuli dzerabha dzinobata, chiyereso chekukora chinokurudzirwa kuyera ukobvu, asi kutarisisa kunofanira kupihwa kunzvimbo yekuyeresa uye mutoro;

E. Pazvinhu zvakatetepa zvefuro, chiyereso chakatsaurirwa chekukora chinokurudzirwa kuyera ukobvu hwacho.

5. Pamusoro pekusarudza michina, ndezvipi zvimwe zvinhu zvinofanira kufungwa nezvazvo pakuyera zviyero?

Nzvimbo yekuyera mimwe mienzaniso inofanira kutariswa seyainomiririra saizi chaiyo yemuenzaniso.

Semuenzaniso, kune majekiseni akakombama akaumbwa nejekiseni, pachava nekona yekudhonza isingapfuure 1° parutivi rwespline, saka kukanganisa pakati pehupamhi hwepamusoro nehupamhi hwepasi kunogona kusvika 0.14mm.

Pamusoro pezvo, sampuli dzakagadzirwa nejekiseni dzichava nekupisa kwakanyanya, uye pachava nemusiyano mukuru pakati pekuyera pakati nepamucheto pesampuli, saka zviyero zvakakodzera zvichatsanangurawo nzvimbo yekuyera. Semuenzaniso, ISO 178 inoda kuti nzvimbo yekuyera yehupamhi hwemuenzaniso ive ±0.5mm kubva pakati pemutsetse wekukora, uye nzvimbo yekuyera ukobvu iri ±3.25mm kubva pakati pemutsetse wekufara.

Pamusoro pekuona kuti zviyero zvacho zvakayerwa nemazvo, kungwarira kunofanirawo kutorwa kudzivirira zvikanganiso zvinokonzerwa nekukanganisa kwevanhu.
