Ki jan yo rezoud flote nan machin gwo twou san fon?

Nan pwosesis la nan gwo twou san fon D ', akòz erè a simetri nan de kwen yo koupe nan egzèsis la ak enkonsistans nan netteté, elatriye, li pral lakòz flote nan pozisyon nan twou pandan pwosesis la perçage. Nan sikonstans nòmal, li difisil pou kontwole valè derive 100mm nan 0.1mm. Anjeneral, twou ki pi egzijan yo pral ale apre perçage. Reaming ka kontwole presizyon dyamèt twou a ak amelyore kalite sifas la. Men, li pa ka korije drift ki te koze pa perçage.

Yo nan lòd yo rezoud pwoblèm sa a, nou kase panse a konvansyonèl ak kwè ke byenke flote a pandan perçage se inevitab, kondisyon an kowaksyalite ka toujou asire pa adapte sèk la deyò nan twou anndan an. Pwosesis espesifik etap yo nan solisyon twou twou twou Drift pozisyon Drift yo se:

(1) Blanking, kite yon maj 2mm pou longè total la.

(2) The left end of the car is exposed to light, and the outer circle of the rough car is φ35.5mm.

(3) Clamp the outer circle that has been rough-turned at the left end, and finish turning the right end face to ensure that the total length is 80±0.05 mm, and drill and ream through holes of φ4.9±0.05 mm.

(4) Remove the burrs at the two ends of the hole, two holes with φ4.9±0.05 mm, and the outer circle of φ34.9 mm is finely turned.

(5) Then process the remaining dimensions based on the outer circle of φ34.9 mm.

In this way, the φ4.9±0.05 mm hole is processed first, and then the other dimensions are processed on the basis of the φ4.9±0.05 mm hole, so that the drift error during the processing of the φ4.9±0.05 mm hole will be used in the subsequent processing Be corrected.
