Maitiro Ekutarisa Kururama kweGranite Straightedge

Granite straightedges maturusi chaiwo anoshandiswa zvakanyanya mumaindasitiri akadai sekugadzira muchina, metrology, uye mekiniki kusangana. Kuve nechokwadi cheiyo granite kutwasanuka kwakakosha pakuvimbisa kuyerwa kwekuvimbika uye kunaka kwechigadzirwa. Pazasi pane akajairwa nzira dzekutarisa kutwasuka uye zvine hukama geometric kushivirira kwegranite straightedges.

1. Perpendicularity yeRutivi Kurwisana neKushanda Surface

Kutarisa perpendicularity yemativi akatwasuka:

• Isa giraniti yakatwasuka pane yakaribrated pamusoro ndiro.

• Isa dial gauge ine 0.001mm yekupedza kudzidza kuburikidza neyakajairwa kutenderera bara uye zero iyo uchishandisa referensi sikweya.

• Hunza iyo dial gauge inosangana nedivi rimwe reiyo yakatwasuka kurekodha iyo perpendicularity kutsauka.

• Dzokorora kune rimwe divi uye rekodha iyo yakanyanya kukanganisa seiyo perpendicularity kukosha.

Izvi zvinoita kuti zviso zvepadivi zvienzane kune nzvimbo yekushanda, kudzivirira kuyerwa kwekuyeresa panguva yekushandisa inoshanda.

2. Bata Nzvimbo Yenzvimbo Yekurongeka kweParallel Straightedge

Kuongorora kupfava kwepasi nekusangana reshiyo:

• Isa chidimbu chakatetepa chemumiririri wekuratidzira kunzvimbo yekushanda kweiyo yakatwasuka.

• Geda pasi zvinyoro nyoro pandiro yesimbi yakatsetseka kana kumwe kutwasanuka kwakaenzana kana kwepamusoro.

• Iyi nzira icharatidza zvinoonekwa zvekusangana.

• Isa gidhi yeplexiglass inoonekera (200 diki masikweya, imwe neimwe 2.5mm × 2.5mm) panzvimbo dzakangoitika pamusoro.

• Verenga chikamu chemakwere ane nzvimbo dzekusangana (muzvikamu zve 1/10).

• Avhareji yereshiyo inobva yaverengwa, inomiririra inobudirira yekubata nzvimbo yebasa rekushanda.

Iyi nzira inopa kuongororwa kwekuona uye kuwanda kweiyo straightedge's surface condition.

3. Kururama kweKushanda Kwepamusoro

Kuyera kutwasuka:

• Tsigira kutwasuka pamakasi akajairwa ari pa2L/9 kubva kumagumo ega ega uchishandisa akaenzana-kureba mabhuroko.

• Sarudza bhiriji rekuyedza rakakodzera zvichienderana nehurefu hwenzvimbo yekushanda (kazhinji nhanho 8-10, inotenderera 50-500mm).

• Chengetedza autocollimator, chiyero chemagetsi, kana mwero wemweya chaiwo kubhiriji.

• Fambisa zambuko nhanho nhanho kubva kumagumo kuenda kune imwe, uchirekodha kuverenga panzvimbo yega yega.

• Musiyano pakati pehukuru uye hushoma hutsika hunoratidza kukanganisa kwekururama kwenzvimbo yekushanda.

Pazviyero zvenzvimbo pamusoro pe200mm, chidimbu chebhiriji (50mm kana 100mm) chinogona kushandiswa kuona kukanganisa kwekutwasuka nepamusoro pekugadzirisa.

4. Parallelism yeKushanda uye Kutsigira Nzvimbo

Parallelism inofanira kusimbiswa pakati pe:

• Nzvimbo dzepamusoro uye dzakaderera dzekushanda kweiyo straightedge.

• Nzvimbo yekushanda uye nzvimbo yekutsigira.

Kana referensi plate isipo:

• Isa rutivi rwekururamisa parutsigiro rwakagadzikana.

• Shandisa lever-type micrometer kana precision micrometer ine 0.002mm girajuation kuyera kureba mutsauko pamwe nehurefu.

• Kutsauka kunomiririra kukanganisa kweparallelism.

Mhedziso

Kuongorora kutwasanuka uye geometric kurongeka kwegranite kutwasanuka kwakakosha pakuchengetedza kuyerwa kutendeseka mumaindasitiri akajeka. Nekuonesa perpendicularity, yekuonana point ratio, kutwasanuka, uye parallelism, vashandisi vanogona kuona kuti mitsetse yavo yegranite inosangana nepamusoro-soro miyero inodiwa kumaindasitiri uye murabhoritari kunyorera.
