Kodi 7:24 mu chogwirira cha BT amatanthauza chiyani? Kodi miyezo ya BT, NT, JT, IT ndi CAT ndi yotani? Masiku ano, zida zamakina a CNC zimagwiritsidwa ntchito kwambiri m'mafakitale. Zida zamakinazi ndi zida zomwe zimagwiritsidwa ntchito zimachokera padziko lonse lapansi, ndi zitsanzo ndi miyezo yosiyana. Lero ndikufuna kulankhula nanu za chidziwitso chokhudza makina ogwiritsira ntchito zida.
Chogwirizira chida ndicho kulumikizana pakati pa chida cha makina ndi chida. Wogwirizira chida ndi ulalo wofunikira womwe umakhudza kukhazikika komanso kusanja kwamphamvu. Siyenera kutengedwa ngati gawo wamba. Concentricity imatha kudziwa ngati kuchuluka kwa kudula kwa gawo lililonse lakumapeto ndi yunifolomu pomwe chida chimazungulira kamodzi; Kusalinganika kwamphamvu kumatulutsa kugwedezeka kwanthawi ndi nthawi pamene spindle izungulira.

Malinga ndi bowo la spindle taper, lagawidwa m'magulu awiri:
Malinga ndi taper wa dzenje chida anaika pa spindle wa pakati Machining, nthawi zambiri amagawidwa m'magulu awiri:
SK chogwirizira chida chapadziko lonse chokhala ndi tepi ya 7:24
HSK chofukizira vacuum ndi taper 1:10
HSK chofukizira vacuum ndi taper 1:10
SK chogwirizira chida chapadziko lonse chokhala ndi tepi ya 7:24
7:24 imatanthawuza kuti tepi ya chogwiritsira ntchito ndi 7:24, yomwe ndi malo osiyana ndi taper ndipo shank ya taper ndi yaitali. Pamwamba pa cone imagwira ntchito ziwiri zofunika nthawi imodzi, zomwe ndi malo enieni a chogwiritsira ntchito poyerekezera ndi chopondera komanso kukanikiza kwa chogwiritsira ntchito.
Ubwino: Sizidzitsekera zokha ndipo zimatha kutsitsa ndikutsitsa zida mwachangu; kupanga chofukizira chida kumangofunika kukonza ngodya ya taper kuti ikhale yolondola kwambiri kuti zitsimikizire kulondola kwa kugwirizana, kotero mtengo wa chotengeracho ndi wotsika kwambiri.
Zoipa: Panthawi yozungulira kwambiri, dzenje lopiringizika lomwe lili kumapeto kwa spindle limakula. Kuchuluka kwa kufalikira kumawonjezeka ndi kuwonjezeka kwa utali wozungulira ndi liwiro lozungulira. Kuuma kwa kugwirizana kwa taper kudzachepa. Pansi pa mphamvu ya kukoka ndodo, kusamutsidwa kwa axial kwa chogwiritsira ntchito kudzachitika. Padzakhalanso zosintha. Kukula kwa radial kwa chogwiritsira ntchito kudzasintha nthawi iliyonse pamene chida chisinthidwa, ndipo pali vuto la kubwereza kosakhazikika kubwereza kulondola.
Zida zonse zokhala ndi tepi ya 7:24 nthawi zambiri zimabwera mumiyezo isanu ndi mafotokozedwe:
1. Muyezo wapadziko lonse IS0 7388/1 (wotchedwa IV kapena IT)
2. Muyezo waku Japan wa MAS BT (wotchedwa BT)
3. German muyezo DIN 2080 mtundu (NT kapena ST mwachidule)
4. American standard ANSI/ASME (CAT mwachidule)
5. Mtundu wa DIN 69871 (wotchedwa JT, DIN, DAT kapena DV)
Njira yomangirira: Chogwirizira chida chamtundu wa NT chimalumikizidwa kudzera pa ndodo yokokera pamakina achikhalidwe, omwe amadziwikanso kuti ST ku China; zida zina zinayi zopatsira zida zimakokedwa pa malo opangira makina kudzera pa rivet kumapeto kwa chogwirizira. zolimba.
Kusinthasintha: 1) Pakadali pano, zida zomwe zimagwiritsidwa ntchito kwambiri ku China ndi mtundu wa DIN 69871 (JT) ndi zida zamtundu wa Japan MAS BT; 2) Zida zamtundu wa DIN 69871 zitha kukhazikitsidwanso pazida zamakina okhala ndi mabowo a spindle taper a ANSI/ASME; 3) Chida chapadziko lonse cha IS0 7388/1 chida chapadziko lonse lapansi chikhoza kukhazikitsidwanso pazida zamakina ndi DIN 69871 ndi ANSI/ASME mabowo a spindle taper, kotero potengera kusinthasintha, chogwirizira chida cha IS0 7388/1 ndicho chabwino kwambiri.
HSK chofukizira vacuum ndi taper 1:10
Chida cha HSK vacuum chimadalira kusinthika kwa chotengeracho. Sikuti 1:10 taper pamwamba pa chofukizira chida kukhudzana 1:10 taper pamwamba pa bowo makina chida spindle, koma flange pamwamba pa chofukizira chida komanso kukhudzana kwambiri ndi pamwamba spindle. Pawiri iyi Njira yolumikizirana ndi pamwamba ndiyabwino kuposa 7:24 chida chapadziko lonse lapansi potengera makina othamanga kwambiri, kukhazikika kwa kulumikizana komanso kulondola kwangozi.
Chida cha HSK vacuum chikhoza kupititsa patsogolo kukhazikika ndi kukhazikika kwa dongosolo ndi kulondola kwazinthu panthawi ya makina othamanga kwambiri, ndikufupikitsa nthawi yosinthira zida. Imagwira ntchito yofunika kwambiri pamakina othamanga kwambiri ndipo ndiyoyenera kuthamanga kwa zida zamakina mpaka 60,000 rpm. Machitidwe a zida za HSK akugwiritsidwa ntchito kwambiri m'mafakitale opangira zinthu monga ndege, magalimoto, ndi nkhungu zolondola.
Zida za HSK zimapezeka mumitundu yosiyanasiyana monga A-mtundu, B-mtundu, C-mtundu, D-mtundu, E-mtundu, F-mtundu, etc. Pakati pawo, A-mtundu, E-mtundu ndi F-mtundu amagwiritsidwa ntchito kwambiri m'malo opangira makina (osintha zida zokha).
Kusiyana kwakukulu pakati pa Mtundu A ndi Mtundu E:
1. Mtundu A uli ndi polowera koma mtundu E alibe. Chifukwa chake, tikulankhula, mtundu A uli ndi torque yokulirapo ndipo imatha kudula molemera. Mtundu wa E umatulutsa torque yocheperako ndipo imatha kudula pang'ono.
2. Kuwonjezera pa groove yopatsirana, chogwiritsira ntchito chida cha A-chida chimakhalanso ndi mabowo okonzekera pamanja, ma grooves otsogolera, ndi zina zotero, kotero kuti malirewo ndi osauka. Mtundu wa E ulibe, choncho mtundu wa E ndi woyenera kwambiri pokonza mofulumira kwambiri. Makina amtundu wa E ndi mtundu wa F ndi ofanana ndendende. Kusiyanitsa pakati pawo ndikuti tepi ya zida zamtundu wa E ndi mtundu wa F (monga E63 ndi F63) wokhala ndi dzina lomwelo ndi wocheperako. Mwanjira ina, ma diameter a flange a E63 ndi F63 onse ndi φ63, koma kukula kwa taper kwa F63 kumangofanana ndi E50. Choncho, poyerekeza ndi E63, F63 adzakhala atembenuza mofulumira (kunyamula spindle ndi yaying'ono).

Momwe mungayikitsire chogwirira cha mpeni
Spring chuck chogwirizira
Amagwiritsidwa ntchito kwambiri pomanga zida zodulira shank zowongoka ndi zida monga zoboola, zodula mphero, ndi matepi. The zotanuka mapindikidwe a circlip ndi 1mm, ndi clamping osiyanasiyana ndi 0.5 ~ 32mm m'mimba mwake.
Msuzi wa Hydraulic
A- Locking screw, gwiritsani ntchito wrench ya Allen kuti mumangitse zokhoma;
B- Tsekani pisitoni ndikusindikiza sing'anga ya hydraulic muchipinda chokulitsa;
C- Chipinda chokulitsa, chomwe chimafinyidwa ndi madzi kuti apange kukakamiza;
D- Thin yokulitsa chitsamba chomwe chimakhazikika ndikuphimba ndodo yolumikizira chida panthawi yotseka.
Zisindikizo za E-Special zimatsimikizira kusindikiza koyenera komanso moyo wautali wautumiki.
Chosungira chida chotenthetsera
Ukadaulo wotenthetsera wotenthetsera umagwiritsidwa ntchito kutenthetsa chida cholumikizira gawo lachosungirako kuti m'mimba mwake chiwonjezeke, ndiyeno chosungira chida chozizira chimayikidwa muchosungira chida chotentha. Chogwiritsira ntchito chida chotenthetsera chimakhala ndi mphamvu yokhotakhota yolimba komanso yokhazikika bwino, ndipo ndi yoyenera kuyika makina othamanga kwambiri. Kuwongolera kobwerezabwereza ndikokwera, kawirikawiri mkati mwa 2 μm, ndipo kutuluka kwa radial kuli mkati mwa 5 μm; ili ndi luso loletsa kusokoneza komanso luso loletsa kusokoneza panthawi yokonza. Komabe, kukula kulikonse kwa chogwiritsira ntchito kumangoyenera kukhazikitsa zida zokhala ndi shank imodzi, ndipo zida zotenthetsera zimafunikira.
