Ukubeka ireferensi nezakhiwo kanye nokusetshenziswa kwamageji asetshenziswa kakhulu

1, umqondo wokuma kwebhentshimakhi

I-datum iyiphoyinti, umugqa, nendawo lapho ingxenye isetshenziselwa khona ukunquma indawo yamanye amaphuzu, imigqa, nobuso. Ireferensi esetshenziselwa ukuma ibizwa ngokuthi ireferensi yokuma. Ukuma kuyinqubo yokunquma indawo efanele yengxenye. Izimbobo ezimbili ezimaphakathi zinikezwe ezingxenyeni zeshaft yokugaya eyicylindrical yangaphandle. Imvamisa, i-shaft ithatha ama-clamp amabili aphezulu, futhi ireferensi yokuma kwayo iyi-eksisi emaphakathi eyakhiwe izimbobo ezimbili ezimaphakathi, futhi ucezu lokusebenza lwakhiwe ngokuzungeza lube indawo eyicylindrical.cnc machining ingxenye

2, imbobo ephakathi

Inqubo evamile yokugaya i-cylindrical ibhekwa ezingxenyeni ze-shaft ezijwayelekile, futhi imbobo yesikhungo sokuklama yengezwe kumdwebo wengxenye njengereferensi yokubeka. Kunemibandela emibili yezimbobo ezimaphakathi ezivamile. Imbobo emaphakathi yohlobo lwe-A iyikhoni engu-60° okuyingxenye yokusebenza yembobo emaphakathi. Isekelwa i-cone ephezulu engu-60 ° ukusetha isikhungo futhi imelane namandla okugaya kanye namandla adonsela phansi omsebenzi. I-cylindrical bore encane ebusweni bangaphambili bekhoni engu-60° igcina okokugcoba ukuze kuncishiswe ukungqubuzana phakathi kwethiphu nembobo emaphakathi ngesikhathi sokugaya. Imbobo emaphakathi yohlobo lwe-B enekhoni yokuvikela engu-120°, evikela unqenqema oluyi-conical engu-60° kumaqhubu, ivamile kuma-workpiece anonemba okuphezulu nezinyathelo zokucubungula ezinde.ingxenye yokunyathela

3. Izidingo zobuchwepheshe zembobo ephakathi

(1) Ukubekezelela ukuyindilinga kwekhoni engu-60° kungu-0.001 mm.

(2) Indawo eyi-conical engu-60° izohlolwa ngendlela ye-gauge yombala, futhi indawo ethintwayo izoba nkulu kunama-85%.

(3) Ukubekezelelana kwe-coaxiality yembobo emaphakathi kuzo zombili iziphetho ngu-0.01mm.

(4) Ubulukhuni obungaphezulu bendawo eyikhonikhi bungu-Ra 0.4 μm noma ngaphansi, futhi azikho iziphambeko ezinjengama-burrs noma ama-bumps.

Ukuze kuhlangatshezwane nezidingo zembobo ephakathi nendawo, imbobo ephakathi ingalungiswa ngalezi zindlela ezilandelayo:

1) Ukugaya imbobo ephakathi ngetshe lamafutha kanye nesondo lokugaya irabha

2) Ukugaya imbobo ephakathi nendawo ngensimbi eyinsimbi

3) Ukugaya imbobo emaphakathi ngesondo lokugaya elingaphakathi elimise okwenzeke

I-4) Ukukhishwa komgodi ophakathi nendawo nge-quadrangular cemented carbide tip

5) Ukugaya umgodi ophakathi nendawo nge-grinder yembobo ephakathi

4, phezulu

Isibambo esiphezulu siyi-Morse cone, futhi usayizi wethiphu uvezwa nge-Morse taper, njengethiphu ye-Morse No. 3. Ingaphezulu liyi-universal fixture esetshenziswa kakhulu ekugayeni okuyi-cylindrical.

5, ama-mandrels ahlukahlukene

I-mandrel iyisici esikhethekile sokubopha isethi yezingxenye ukuze kuhlangatshezwane nezidingo zokunemba zokugaya kwangaphandle kwengxenye.ingxenye yepulasitiki

6, ukufundwa kwe-vernier caliper

I-vernier caliper iqukethe uzipho lokulinganisa, indikimba yerula, igeji yokujula kwe-vernier, kanye nesikulufu sokubopha.

7, ukufundwa kwe-micrometer

I-micrometer iqukethe irula, i-anvil, isikulufu se-micrometer, idivayisi yokukhiya, umkhono ogxilile, isilinda esihlukile, nedivayisi yokulinganisa amandla. Indawo yokulinganisa ye-micrometer kufanele ihlanzwe futhi i-zero ye-micrometer kufanele ihlolwe ngaphambi kokusetshenziswa. Naka ukuma kwesilinganiso esifanele lapho ukala.
