Amaliy ish tish frezalash stanoklarini sozlash

5M32 stanokni sozlash


Qiya tishli g’ildiraklar vertikal surish bilan
m_n= 3 mm; Z=60; β = 34⁰30’36’’; spiral o‘ng
k = 1; d_fr = 112; φ = 1⁰40^’; spiral o‘ng
v = 35 mm/min; g’ildirak tishi bo‘ylab surish kattaligi - S₀=1,3 ayl/min.


Bosh harakat zanjiri
Tezliklar gitarasini uzatish nisbati va g’ildiraklari

Vertikal surish zanjiri
Vertikal surish qiymati:


S_B=S₀*cosβ=1,3*0,824=1,07 mm/ayl.

Surish gitarasi uzatish nisbati va g’ildiraklari



1,52*b₂=96; b₂ = 63; olamiz b₂ = 64;.
U holda


d₂ = 32; .


Differensial gitarasini sozlash
Differensial gitarasini uzatish nisbatini quyidagi sozlash formulasi bo‘yicha hisbolaymiz:
.
Dastlabki ma’lumotlarni qiymatlarini o‘rniga quyib


sin34⁰30^’36^’’=0,56655.

O‘nlik kasrni oddiyga almashtirib va surat va maxrajni oddiy ko‘paytuvchilarga ajratib, jadval bo‘yicha g’ildirakni aniqlaymiz:



Frezalash supportining qaytish burchagi

γ _fr.sup= φ – β =32⁰50^’36^’’.


5M32 stanokni sozlash


Quyidagi ma’lumotlar bo‘yicha cheryak g’idiraklarni radial surish usulida kesish: Z= 75; m=1,5 mm; D_fr = 72,6 mm; k=1; V=32 m/min.
Shpindelning talab qilingan aylanishlar chastotasini aniqlaymiz:





n_st=125 ayl/min qabul qilamiz.
Bulish va obkatlash zanjiri
Sozlash formulasi bo‘yicha gitara shesternyalarining tishlari sonini aniqlaymiz:

Frezalash supportini qaytish burchagi γ=0.

Qirqish chuqurligi:


t=2,25*m=2,25*1,5=3,375 mm.
