Ndeipi chiyero chenyika chehukuru hwekushivirira huwandu hwezvikamu zvejekiseni remotokari?
Iyo yenyika chiyero chehukuru hwekushivirira huwandu hwemotokari jekiseni zvikamu ndeye GB/T 14486-2008 "Plastiki Yakaumbwa Zvikamu Saizi Kushivirira".Iyi chiyero inotsanangudza kushivirira kwezvikamu zvepurasitiki zvakaumbwa, uye inokodzera zvikamu zvepurasitiki zvakaumbwa zvinoiswa jekiseni, kudzvanywa uye kubaiwa.
Zvinoenderana nechiyero chenyika, saizi yekushivirira huwandu hwezvikamu zvejekiseni dzemotokari dzakakamurwa kuita A uye B mamaki.Kirasi A chaiyo inodiwa yakakwira, yakakodzera kune chaiyo jekiseni zvikamu;Grade B precision zvinodiwa zvakaderera, zvakakodzera kune general jekiseni zvikamu.Iyo chaiyo tolerance range ndeyotevera:
(1) Linear dimensional kushivirira:
Linear dimensions zvinoreva mativi pakureba.Kune Kirasi A jekiseni akaumbwa zvikamu, kushivirira kwemhando yemutsara saizi ndeye ± 0.1% kusvika ± 0.2%;Kune zvikamu zvakaumbwa zveKirasi B majekiseni, kushivirira kwemhando yezviyero zvemutsara ndeye ± 0.2% kusvika ± 0.3%.
(2) Kushivirira kwekona:
Angle tolerance zvinoreva kutsauka kweAngle muchimiro uye kushivirira kwechinzvimbo.Kune Kirasi A jekiseni akaumbwa zvikamu, iyo Angle kushivirira ndeye ± 0.2 ° kusvika ± 0.3 °;Kune zvikamu zvakaumbwa zveKirasi B jekiseni, kushivirira kweAngle kuri ± 0.3 ° kusvika ± 0.5 °.
(3) Fomu uye kushivirira chinzvimbo:
Mafomu uye kushivirira kwechinzvimbo kunosanganisira kutenderera, cylindricity, parallelism, verticality, etc. Kwekirasi A jekiseni zvikamu, fomu uye chinzvimbo kushivirira zvinopihwa zvinoenderana nekirasi K muGB/T 1184-1996 "Shape uye Position Tolerances isina kutaurwa Tolerance Value";Kune zvikamu zvemajekiseni ekirasi B, fomu uye kushivirira kwechinzvimbo zvinopihwa zvinoenderana nekirasi M muGB/T 1184-1996.
(4) Kushata kwepamusoro:
Kukasharara kwepamusoro (Surface roughness) zvinoreva mwero wekusaenzana kwemicroscopic pavhu rakagadzirwa.Yekirasi A jekiseni akaumbwa zvikamu, pamusoro roughness iri Ra≤0.8μm;Yekirasi B jekiseni zvikamu zvakaumbwa, iyo roughness iri Ra≤1.2μm.
Uye zvakare, kune zvimwe zvakakosha zvinodiwa zvemotokari jekiseni zvikamu, senge mapaneru emidziyo, yepakati console, nezvimwe, iwo dimensional kushivirira zvinodiwa zvinogona kunge zvakakwirira, uye zvinoda kudzorwa zvinoenderana nezvinodiwa zvechigadzirwa.
Muchidimbu, chiyero chenyika chechiyero chekushivirira kwezvikamu zvejekiseni zvemotokari ndeye GB/T 14486-2008 "Dimensional kushivirira kwePlastiki yakaumbwa zvikamu", iyo inotsanangura zvinodiwa zvekushivirira kwedimensional, chimiro uye kushivirira chinzvimbo uye kushata kwepasi kwepurasitiki yakaumbwa. zvikamu.Mukugadzirwa chaiko, zvinodikanwa kugadzirisa uye kugadzirisa zvinoenderana nezvinodiwa zvechigadzirwa uye mold dhizaini kuti ive nechokwadi chekuti zvikamu zvejekiseni zvemotokari zvinosangana nezvinodiwa.
