Kuboora chii?
Kuboora gomba sei?
Nzira yekuita sei kuchera zvakanyanya?
Inotsanangurwa zvakajeka pazasi, ngatitarisei.
1. Mafungiro ekutanga ekuchera
Kazhinji, kuchera zvinoreva nzira yekugadzira iyo inoshandisa chibooreso kugadzira maburi pachigadzirwa. Kazhinji, pakuchera zvigadzirwa pamushini wekuchera, dhiri rinofanirwa kupedzisa mafambiro maviri panguva imwe chete:
① Main kufamba, ndiko kuti, kutenderera kwechibooreso chinotenderedza axis (kucheka kufamba);
②Secondary movement, ndiko kuti, kufamba kwemutsara kwechibooreso bhiti pamwe chete neaxis nzira yakananga kune workpiece (feed movement).
Pakuchera, nekuda kwekukanganisa mune dhizaini dhizaini, mamaki anozosiiwa pane zvakagadziriswa zvikamu zvechigadzirwa, zvichikanganisa kunaka kwekugadzirisa kweiyo workpiece. Kurongeka kwekugadzirisa kunowanzo kuve pazasi IT10 nhanho, uye kushata kwepamusoro kunenge Ra12.5μm, inova yechikamu chakaomarara machining. .
2. Kuchera maitiro ekushanda
1. Kumaka: Usati wachera, tanga wanzwisisa zvinodiwa pakudhirowa. Zvinoenderana nezvinodiwa zvakajairwa pakuchera, shandisa maturusi kumaka mutsara wepakati wenzvimbo yegomba. Mutsara wepakati unofanirwa kuve wakajeka uye wakarurama, uye mutete unoita nani. Mushure mekudhirowa mutsara, Edza nevernier calipers kana mutongi wesimbi.
2. Dhirowa sikweya yekuongorora kana denderedzwa rekuongorora: Mushure mekudhirowa mutsara uye nekupfuura ongororo, yekuongorora sikweya kana yekuongorora denderedzwa ine yepakati mutsara wegomba sepakati pe symmetry inofanirwa kudhirowewa semutsetse wekuongorora panguva yekuchera bvunzo kuti iite kuongorora. panguva yekuchera. uye kudhirowa kwakaringana.
3. Kuongorora nekurova: Mushure mekudhirowa kunze kwenzvimbo yekuongorora inoenderana kana denderedzwa rekuongorora, kuongorora nekurovera kunofanira kuitwa nemazvo. Tanga ita poindi diki, woyera kakati wandei munzira dzakasiyana dzemuchinjiro wepakati kuti uone kana gomba rechibhakera rakaroverwa pamharadzano yemuchinjiko wepakati mutsara, wobva wabaya sampuli munzira yakatwasuka, yakatenderera, uye yakafara. kuitira kuiswa kwakarurama. Banga riri pakati.
4. Clamping: Shandisa rag kuchenesa muchina tafura, fixture pamusoro, uye workpiece datum pamusoro, uye ipapo clamp workpiece. Iyo clamping inofanirwa kuve yakatsetseka uye yakavimbika sezvinodiwa, uye yakanakira kubvunza uye kuyerwa chero nguva. Izvo zvinodikanwa kuterera kune iyo clamping nzira yeworkpiece kudzivirira iyo workpiece kubva pakuremara nekuda kwe clamping.
5. Test drilling: Test drilling inofanira kuitwa kusati kwave kuchera kwakarongeka: gadzirisa chisel edge yechibhorani nepakati pegomba uye chera gomba risina kudzika, uye zvino tarisa nemaziso kuti nzira yegomba isina kudzika yakarurama here. Izvo zvinodiwawo kugara uchigadzirisa kutsauka kuita gomba risina kudzika uye denderedzwa rekuongorora Coaxial. Kana kutsauka kuri kudiki, workpiece inogona kusundidzirwa kune yakatarisana nekutsauka uku uchidhirowa kuti uwane kururamisa zvishoma nezvishoma.
6. Kuchera: Kuchera muchina kunowanzoenderana nekushanda kwekudya kwemaoko. Kana iyo bvunzo yekuchera chinzvimbo chechokwadi ichidikanwa, kuchera kunogona kuitwa. Paunenge uchidyisa nemaoko, simba rekudyisa harifanire kuita kuti chibooreso chikotame kudzivirira gomba kuti risatsvedzerwe.
3. Nzira dzepamusoro dzekuchera kunyatsoita
1. Kurodza chibooreso ndiko kutanga kwezvose
Iyo inoenderana drill bit inofanira kusarudzwa yekurodza isati yaboora. Pamusoro pekuona chokwadi chekona ye vertex, clearance angle, uye chisel edge bevel, chibooreso chakarodzwa chine hurefu hwakafanana hwemacheto maviri makuru ekucheka uye anoenzanirana nepakati mutsara wekuchera bhiti, uye maviri makuru eflank nzvimbo akatsetseka. , kuitira kuti zvive nyore kuisa pakati uye kuderedza kushata kwemadziro egomba. , iyo chisel edge uye iyo huru yekucheka inofanirawo kuve yakanyatsogadziriswa (zvakanakisisa kugaya rough pane grinder kutanga, uye ipapo kukuya zvakanaka padombo remafuta).
Xinfa CNC zvishandiso zvine hunhu hwemhando yakanaka uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:

2. Kudhirowa kwemutsara kwakarurama ndiyo hwaro
Paunenge uchishandisa chiyero chekukwirira kumaka mitsetse nenzira kwayo, kutanga pane zvese, unofanirwa kuve nechokwadi chekuti kurongeka kwacho kwakaringana. Paunenge uchimaka, ita shuwa kuti kona iri pakati peakona yetsono uye ndege yekumaka yeworkpiece ine madhigirii makumi mana kusvika makumi matanhatu (pamwe negwara rekumaka), kuitira kuti mitsetse yakadhirowewa yakajeka uye kunyange. Ngwarira kusarudzwa kweiyo scribing datum ndege. Iyo ndege yedatum inofanirwa kugadziriswa nemazvo uye kupfava kwayo uye perpendicularity kune dziri padyo nenzvimbo dzinofanirwa kuve nechokwadi. Mushure megomba chinzvimbo chemuchinjikwa mutsara wadhonzwa, kuitira kuve nechokwadi kurongeka kuri nyore paunenge uchichera, shandisa iyo yepakati punch kuburitsa nzvimbo yepakati pamuchinjiko (iyo punch inofanirwa kunge iri diki uye kutungamira kunofanirwa kuve kwakarurama).
3. Kuroverera chaiko ndiko kwakakosha
Kazhinji, kumakomba ane dhayamita isingasviki 6 mm, kana iko kurongeka kusina kukwirira, unogona kushandisa mapikisi emaoko kuti ubatanidze workpiece yekuchera; pamakomba pakati 6 uye 10 mm, kana workpiece nguva dzose uye flat, unogona kushandisa flat-mhino pliers, asi workpiece inofanira kuva The pamusoro perpendicular kuti drilling machine spindle. Paunenge uchichera gomba rine dhayamita yakakura, flat-nose pliers inofanira kugadziriswa nebhoti yekumanikidza ndiro; kune makuru maworkpiece ane dhayamita yekuboora inodarika 10 mm, shandisa nzira yekudzvanya ndiro yekuroverera kudhiraivha.
4. Kuwana kiyi nemazvo ndiyo kiyi
Mushure mokunge workpiece yakasungirirwa, usakurumidza kudonhedza drill. Kuenzanisa kunofanira kuitwa kutanga. Kurongeka kunosanganisira kurongeka kwakamira uye kurongeka kwesimba. Iyo inonzi static alignment inoreva kurongeka kusati kwatanga muchina wekuchera, kuitira kuti mutsara wepakati wemuchina wekuchera spindle uye mharadzano yeworkpiece cross line inowirirana. Iyi nzira yakachengeteka uye yakanakira vanotanga uye iri nyore kubata. Nekudaro, hazvifungidzire swing yemuchina wekuchera spindle, semuenzaniso. uye zvimwe zvinhu zvisina chokwadi, iko kuchera kwakadzika. Dynamic alignment inoitwa mushure mekunge muchina wekuchera watanga. Panguva yekurongeka, zvimwe zvinhu zvisina chokwadi zvinotorwa, uye kurongeka kwacho kunenge kwakakwirira.
5. Kunyatsoongorora kunokosha
Kuongorora kunogona kunyatso uye nenguva kuona kurongeka kwegomba kuitira kuti matanho anodiwa atorwe kubhadhara. Kumakomba ane kucheresa kwepamusoro, isu tinowanzo shandisa kuchera, kugadzirazve, uye kugadzirisa zvakare maitiro. Mushure mekuboora buri diki padanho rekutanga, shandisa caliper kuona kukanganisa kubviswa kubva pakati pegomba repasi kusvika kune datum. Mushure mechiyero chaicho, verenga nzvimbo yegomba rezasi uye nzvimbo yakakodzera. Kana kukanganisa kusiri kukuru kupfuura 0.10mm, unogona kuwedzera gomba. Nemazvo wedzera chibooreso chekona, netesa otomatiki centering mhedzisiro, sunda nemazvo workpiece munzira yakanaka, uye zvishoma nezvishoma wedzera chibooreso chepakati dhayamita kutsiva. Kana kukanganisa kwakakura kudarika 0.10mm, faira yakatenderedzwa inogona kushandiswa kucheka madziro epadivi egomba rezasi. Chikamu chakatemwa chinofanira kubatanidzwa nearc yegomba rezasi mukuchinja kwakanaka.
