Kif issolvi d-drift tal-magni tat-toqba fil-fond?

Fil-proċess ta 'makkinarju ta' toqba fil-fond, minħabba l-iżball ta 'simetrija taż-żewġ truf tat-tqattigħ tat-trapan u l-inkonsistenza ta' sharpness, eċċ., Se tikkawża d-drift tal-pożizzjoni tat-toqba matul il-proċess tat-tħaffir. F'ċirkostanzi normali, huwa diffiċli li tikkontrolla l-valur tad-drift ta '100mm fi ħdan 0.1mm. Ġeneralment, it-toqob aktar impenjattivi se jiġu reamed wara t-tħaffir. Ir-reaming jista 'jikkontrolla l-eżattezza tad-dijametru tat-toqba u jtejjeb il-kwalità tal-wiċċ. Iżda ma tistax tikkoreġi d-drift ikkawżat mit-tħaffir.

Sabiex issolvi din il-problema, aħna kissru l-ħsieb konvenzjonali u emmnu li għalkemm id-drift waqt it-tħaffir huwa inevitabbli, ir-rekwiżit ta 'koassjalità xorta jista' jiġi żgurat billi jiġi adattat iċ-ċirku ta 'barra għat-toqba ta' ġewwa. Il-passi speċifiċi tal-proċess tas-soluzzjoni tad-drift tal-pożizzjoni tat-toqba tal-magni tat-toqba profonda huma:

(1) Blanking, ħalli marġini ta '2mm għat-tul totali.

(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.
