Kana dhipatimendi remhando yepamusoro richitaura nezveplate yegranite pamusoro, mutsetse mumwe chete unonyanya kukosha padhirowa ndiwogiredhi. Giredhi iri rinotsanangura kushivirira kwakasimba kunofanirwa kusimbiswa nemugadziri, uye rinotarisa zvakananga kana plate yacho yakakodzera basa rekugadzirisa, kuongororwa kunouya, kana kurongeka kwenzvimbo yekutenga. Dambudziko nderekuti mitemo mina mikuru inoshanda pamwe chete mukutenga kwenyika dzese: ChiGermanDIN 876, wekuAmericaASME B89.3.7, ChiChineseGB/T 20428, uye USTsanangudzo yeFederal GGG-P-463cGwaro iri rinotsanangura zvinorehwa negiredhi rega rega, maitiro ekuverenga kushivirira kwe flatness, uye maitiro ekusarudza giredhi rinonyanya kushanda pakushandisa kwako.
Chii Chinotsanangurwa Nekuti "Giredhi" Chaizvo?
Giredhi ikirasi yerunyoro, kwete tsananguro yedombo pacharo. Pagiredhi rega rega, chiyero chinotsanangura kutsauka kukuru kwenzvimbo yekushanda kubva papuratifomu chaiyo, yakayerwa padivi pedhizaini yeplate uye inoratidzwa nema micrometer (kana mainji). Mitemo miviri inoshanda pamatanho ese:
- Kushivirira kunoyera nehukuru.Ndiro ye2000 × 1000 mm yemhando imwe chete ine kutsungirira kwakapetwa kaviri kupfuura kwendiro ye1000 × 630 mm. Gara uchienzanisa kutsungirira kuri pahurefu hwakafanana.
- Giredhi rega rega rinenge hafu yekutsungirira kwerinotevera.Kukwira giredhi rimwe chete (semuenzaniso, 0 → 00) kunoderedza kutsauka kunobvumidzwa nehafu; kudzika giredhi rimwe chete kunopeta kaviri. Ndosaka kusarudza giredhi rakakodzera kuchikanganisa zvikuru mutengo.
Vatengesi vane mukurumbira vanoongorora ndiro yega yega zvichienderana nechiyero chakakodzera munzvimbo inodzorwa nekupisa (zvichida 20 °C) uye vanopa chitupa chekuongorora kana chekuongorora chine hunhu hwakayerwa. Kana quotation isingataure chiyero chakajairwa, giredhi uye chiyero che flatness chakabvumidzwa, chitore sechisina kukwana — ona zvinyorwa zvedu pakuyera nekuongorora granite.
DIN 876 Magiredhi (000 / 00 / 0 / 1 / 2)
DIN 876-1 ndiyo chiyero chinonyanya kutaurwa nezvacho muEurope neAsia. Inotsanangura mamakisi mashanu, kubva paGiredhi 000 chaiyo kusvika kuGiredhi 2 reworkshop. Kushivirira kwakajairika kweplate ine1000 mm yakatarisanadziri pamusoro pe:
| Giredhi reDIN 876 | Kureba Kwakajairika (1000 mm yakatambanudzwa) | Kushandiswa Kwakajairika |
|---|---|---|
| 000 | ≈ 2.5 µm | Mitemo yekutarisa, marabhoritari ekugadzirisa |
| 00 | ≈ 5 µm | Kuyera kwakarurama, kuyera chiyero, CMM reference |
| 0 | ≈ 10 µm | Makamuri ekuongorora akajairika, madhipatimendi emhando yepamusoro |
| 1 | ≈ 20 µm | Basa rekushandisa, jig uye kugadzira zvinhu |
| 2 | ≈ 40 µm | Kurongeka kwemusangano nekumaka kwakajairika |
DIN 876 giredhi 00 kutsetsekandiyo chiyero chinonyanya kubvunzwa nemakambani ekuongorora kana ndiro yacho ichitsigira michina yekuyera kana kuti inoshanda senzira yekuongorora. Kuti muenzanise nemazvo, garai muchibvunza vatengesi kuti vataure kukosha kwakasimbiswa padivi chaipo pendiro yamuri kutenga, uye simbisai kutikunyatsorongeka kweplate yegranite pamusoroinotsigirwa nechitupa chakanyorwa.
Magiredhi eASME B89.3.7 (AA / A / B)
Muyero weAmerican ASME B89.3.7 unoshandisa mamakisi emabhii matatu, akaverengerwa kubva pamafomura zvichibva pamutsetse wedhiraivha pane tafura yakatarwa:
- Giredhi AA (Giredhi reRabhoritari)— kushivirira kwakanyanya, kwakagadzirirwa marabhoritari emetrology uye ma master reference plates.
- Giredhi A (Giredhi reKuongorora)— inokwana kaviri kushivirira kweAA; sarudzo yakajairika yemadhipatimendi ekudzora mhando.
- Giredhi B (Giredhi reZvishandiso)— inokwana kaviri A tolerance; yakakodzera kuronga, kugadzira maturusi uye basa rekugadzira machining.
Senzira yekutsanangura zviri nyore, ASME Grade AA inoenderana neDIN 876 Grade 00, uye Giredhi A iri pedyo neDIN Grade 0. Mafomula acho akakosha pakuenzanisa makotesheni: vatengesi vaviri vanotaura ma "Grade A" maplate ehukuru hwakasiyana havasi kupa kushivirira kwakafanana kunze kwekunge diagonal yakafanana.
GB/T 20428 uye Federal Spec GGG-P-463c
Mwero wenyika yeChinaGB/T 20428pamapureti epamusoro egranite anotevera chimiro chekirasi che000 / 00 / 0 / 1 / 2 uye pfungwa yekushivirira seDIN 876, saka mapureti akagadzirwa neChina ane chitupa cheGB 00 anogona kuongororwa zvichienderana nezvinodiwa neDIN 00 - chero bedzi mugadziri akaongorora tembiricha yakadzorwa uye akanyora zvabuda.
Nyika yeUSTsanangudzo yeFederal GGG-P-463cndiyo gwaro rekare rehurumende rinoshandisawo magiredhi eAA / A / B. Matender mazhinji ehurumende yeUS uye madhirowa ekare achiri kutaura nezvawo. Rakatsiviwa neASME B89.3.7 mubhizinesi, asi mazita emagiredhi anoramba aripo padhirowa, saka mapoka ekutenga anofanira kusimbisa kuti ndeapi gwaro rinotenderwa kana dhirowa richiti "Giredhi A" chete.
Kuenzanisa Kwemagiredhi Akaenzana (Kunoratidza)

Cherechedza: matafura ari pamusoro apa mienzaniso inoratidza divi re ~1000 mm. Gara uchitarisa ma "tolerance values" chaiwo zvichienderana neshanduro yazvino yechiyero chinoshanda, uye kumbira data rakayerwa nemugadziri.
Maitiro Ekuverenga uye Kusimbisa Tsananguro yeFlatness
- Tarisa chiyero chereferensi uye chinyorwa— “Giredhi 00″ isina zita rakajairika (DIN 876, GB/T 20428, nezvimwewo) hazvina kunyatsojeka.
- Simbisa saizi yedhayagiramu inoshandiswa pakushivirira— kushivirira kunotsanangurwa pamusoro pedhayagiramu, kwete upamhi.
- Bvunza nezvekuti nzvimbo yacho yakati sandara uye kuti kuverenga kwacho kwakanyatsojeka sei— ndiro inogona kusvika yakati sandara asi iine kutenderera kwenzvimbo iyo inokanganisa kuyerwa kwezvikamu zvidiki.
- Inoda chitupa chine hunhu hwakayerwa uye hunogona kuteverwa— kuyerwa kwakanyatsorongwa, kunoteverwa zvakanaka pasi pemamiriro ekunze e20°C ndiko kunoshandura chirevo chekushivirira kuita humbowo. Ichi chikamu chikuru chedumaitiro ekuongorora nekugadzirisa.
- Sarudza nzvimbo yekumira nesystem yekutsigira— ndiro yeGiredhi 00 iri pachigadziko chisina kukwana haizobati chimiro chayo chakabvumidzwa. Zvitsigiro zvine mapoinzi matatu kana kuti zvinodzivirira madziro chikamu chepakeji yekunyatsojeka.
Maitiro Ekusarudza Giredhi Rakakodzera Pasina Kubhadhara Zvakawandisa
Kutenga zvinhu zvakati wandei kupfuura zvinodiwa ndiko kuraswa kunowanzoitika; kutenga zvinhu zvakawandisa ndiko kukanganisa kunodhura zvikuru. Mazano anoshanda kubva kumazana emapurojekiti akaitwa neMaitiro ekugadzira eZHHIMG®:
- Enzanisa giredhi nechiridzwa, kwete bhurocha.CMM inoda nzvimbo yakagadzikana yekutarisa (Giredhi 00/A yakajairika), nepo tafura yekumaka muchitoro chekugadzira isingabatsire chero chinhu kubva kuGiredhi 000.
- Tenga saizi kamwe chete, nyora kaviri.Zvakachipa kutenga saizi chaiyo ine giredhi rakakodzera izvozvi pane kudzokorodza kana kutsiva ndiro yakasarudzwa kuti ishande pane imwe giredhi isina kusimba zvakanyanya.
- Funga nezvemaledges, mainsert uye ma thread bosses padanho rekusarudza.Kuzviwedzera gare gare zvinokanganisa kusatsetseka uye zvinobvisa chitupa.
- Ronga nguva dzekugadzirisazve.Kunyangwe ndiro yegranite yakagadzikana inofanira kuongororwazve nguva nenguva; kutenderera kwesimba remvura kunoitika zvishoma nezvishoma uye hakuoneki.
Kune mapurojekiti apo ndiro yacho yakabatanidzwa mumuchina kana sisitimu yekuyera pane kushandiswa yakazvimirira, zvinodiwa zvejometri zvinowanzo nyorwa pachikamu chimwe nechimwe padhirowa — timu yedu inogona kuongorora kushivirira uye kutsigira zvese zvinodiwa, kubva pakusarudzwa kwezvinhu kusvika pakuendeswa kwakasimbiswa, sezvakatsanangurwa mudura redu.kugona kwegranite chaiyo.
Mhedziso
Magiredhi egranite pamusoro peplate mutauro unogovaniswa pakati pebazi rako remhando yepamusoro nemugadziri - asi chete kana munhu wese akataura zvakafanana, saizi uye kukosha kwakasimbiswa. Kunyangwe dhizaini yako ichida DIN 876 Grade 00, ASME Grade AA kana GB/T 20428 Grade 0, ZHHIMG® inogadzira uye inobvumidza kune ese mana ma framework, ine chiyero chinoteverwa mumamiriro ekunze anodzorwa nekupisa.
