1. Iimpawu zeZakhiwo zoMsebenzi
Ubume be-workpiece enodonga oluncinciiintsimbi zamavilii-fan shape, i-material yi-QT600, ukuqina yi-187-255 HBW, ngaphakathi ngumngxuma okhethekileyo, kwaye inxalenye encinci yi-4 mm kuphela. Iimfuno zokuchaneka kwe-dimensional zebhloko yebhalansi ziboniswe kuMzobo 1. Ububanzi bomngxuma ophakathi B benchmark yi-Φ69.914-69.944 mm, kwaye ukunyamezela yi-0.03 mm kuphela. Apha ngezantsi kukho umngxuma ongenanto. Ukusika okwethutyana kwenziwa xa kulungiswa umngxuma wereferensi yeC kunye nesangqa sangaphandle. Ubukhulu bodonga apha bu-4 mm kuphela, okulula ukuvelisa uxinzelelo lokusika kunye ne-deformation kunye nokuchaphazela ubungakanani bokunyamezela kwe-reference ye-B, eyona nto inzima kwi-workpiece processing.
2. Iingozi ezifihlakeleyo zobuGcisa besiNtu
Iindawo ezinodonga olubhityileyo zikhubazeka ngokulula ngexesha lenkqubo yokusila, ikakhulu ngenxa yokonakala okubangelwa kukusika uxinzelelo kunye nokuncamathela . Iskimu sokusetyenzwa kwemveli sicutshungulwa liziko lomatshini le-CNC kunye ne-CNC lathe, eyahlulahlulwe kwiinkqubo ezimbini. Enye yinkqubo ye-OP10. Sebenzisa i-Φ60 mm i-disc milling cutter ibe rhabaxa kwaye ugqibezele inqwelomoya ephezulu ukuya kubukhulu bomzobo, sebenzisa i-Φ20 mm i-alloy milling cutter kwi-rough milling kumngxuma wangaphakathi Φ51.04-51.07 mm ukuya ku-Φ50.7 mm (shiya i-0.3-0.4 mm), sebenzisa i-Φ20 mm i-alloy cutter yokusila erhabaxa yokusila umngxuma wangaphakathi Φ69.914～69.944 mm ukuya ku-Φ69.6 mm (shiya 0.3～0.4 mm), umngxuma ongaphakathi odikayo Φ51.04～51.07 mm.69Φ4～49 mm.9 Φ49 mm. nge-cutter ekruqulayo, i-drill 2 × Φ18 mm enemingxuma emibini emincinci. Okwesibini yinkqubo ye-OP20. Isangqa sangaphandle "C" sokujika okukrakra kunye nokucothayo kwiimfuno zobugcisa bomzobo.
Ubunzima bomatshini beiintsimbi zamavili, umngxuma wereferensi B, wenziwa ubungakanani obufunwa ngumzobo kwinkqubo ye-OP10. Susa i-workpiece kwaye ulinganise ububanzi bomngxuma wereferensi B, Φ69.914 ~ 69.944 mm, kunye nephutha le-ovality yi-0.005 ~ 0.015 mm, kwaye ubungakanani buhlangabezana neemfuno zomzobo. Nangona kunjalo, emva kokuba i-OP20 icutshungulwe, susa i-workpiece kwaye ulinganise ububanzi bomgodi wokubhekisela we-B, Φ69.914-69.944 mm, kunye nephutha le-ovality yi-0.03-0.04 mm. Ingabonwa ukuba ububanzi bugqithise iimfuno zomzobo.
3. Isisombululo
Phucula izixhobo zokusebenza. Ingaba uyilo lwesixhobo sokugoba sichanekile kunempembelelo ethe ngqo ekuqinisekiseni ukuchaneka komatshini wesixhobo sokusebenza, ukuphucula imveliso yabasebenzi kunye nokunciphisa ukuqina kwabasebenzi. Ngenxa yeempawu zeendawo ezinodonga olubhityileyo, amandla okuqinisa ngokugqithisileyo okanye amandla angalinganiyo aya kubangela ukuguqulwa kwe-elastic ye-workpiece, okuya kuchaphazela ukuchaneka kobukhulu kunye nokunyamezela kobume benxalenye, kwaye ekugqibeleni kukhokelela kubungakanani benxalenye esetyenzisiweyo. ngenxa yokunyamezelana. Ukuze ucombulule le ngxaki, imodeli kunye nobukhulu be-cylinder ye-clamping kunye ne-cylinder yenkxaso kufuneka ikhethwe ngokucokisekileyo xa kuyilwa i-hydraulic tooling.
