Zolakwa zazikulu zisanu ndi zinayi pakupanga makina, ndi angati omwe mukudziwa?

Kulakwitsa kwa Machining kumatanthauza kuchuluka kwa kupatuka pakati pa magawo enieni a geometric (kukula kwa geometric, mawonekedwe a geometric ndi malo ogwirizana) a gawolo pambuyo pokonza ndi magawo abwino a geometric.

Mlingo wa mgwirizano pakati pa magawo enieni a geometric ndi magawo abwino a geometric pambuyo popangidwa ndi makina olondola. Zolakwika zazing'ono zamakina, zimakulitsa kuchuluka kwa kufanana ndikukweza kulondola kwa makina.7075 aluminiyamu Machining

Kulondola kwa Machining ndi cholakwika cha makina ndi njira ziwiri zavuto. Chifukwa chake, kukula kwa cholakwika cha makina kumawonetsa kuchuluka kwa kulondola kwa makina. Zifukwa zazikulu za zolakwika za makina ndi izi:

1. Kupanga zolakwika za chida cha makina

Cholakwika chopanga chida cha makina chimaphatikizapo cholakwika chozungulira cha spindle, cholakwika cha njanji yowongolera ndi cholakwika cha chain transmission.

Kulakwitsa kwa spindle kumatanthawuza kusinthika kwa nsonga yeniyeni yozungulira ya spindle yogwirizana ndi ma axis ake ozungulira nthawi iliyonse, zomwe zimakhudza kulondola kwa chogwirira ntchito chomwe chiyenera kukonzedwa. Zifukwa zazikulu za cholakwika chozungulira cha spindle ndi cholakwika cha coaxiality cha spindle, cholakwika cha kunyamula komweko, cholakwika cha coaxiality pakati pa ma bearings, ndi kuzungulira kwa spindle. Sitima yolondolera ndiye chizindikiro chodziwira ubale wapagawo lililonse la chida cha makina pazida zamakina, komanso ndiye chizindikiro cha kayendedwe ka zida zamakina.aluminium cnc Machining

Zolakwika zopanga njanji yowongolera yokha, kuvala kosagwirizana kwa njanji yowongolera komanso mawonekedwe oyika ndizofunika kwambiri zomwe zimapangitsa cholakwika cha njanji yowongolera. Vuto la unyolo wopatsirana limatanthawuza cholakwika choyenda pakati pa zinthu zopatsirana kumayambiriro ndi kumapeto kwa unyolo wotumizira. Zimayambitsidwa ndi zolakwa za kupanga ndi kusonkhanitsa kwa chigawo chilichonse muzitsulo zotumizira, komanso kuvala panthawi yogwiritsira ntchito.

2. Cholakwika cha geometric chida

Chida chilichonse chidzavala mosakayikira panthawi yodula, zomwe zingayambitse kusintha kwa kukula ndi mawonekedwe a workpiece. Chikoka cha chida cholakwika cha geometric pa cholakwika cha makina chimasiyanasiyana ndi mtundu wa chida: pomwe chida chokhazikika chimagwiritsidwa ntchito popanga makina, cholakwika chopanga chida chidzakhudza mwachindunji kulondola kwa makina a workpiece; kwa zida zonse (monga kutembenuza zida, etc.), zolakwika zake zopanga Zilibe zotsatira zachindunji pakulakwitsa kwa makina.

3. Kulakwitsa kwa geometric pakukonzekera

Ntchito ya fixture ndi kupanga workpiece yofanana ndi chida ndi makina chida kukhala ndi malo olondola, kotero kulakwitsa geometric wa fixture ali ndi chikoka chachikulu pa kulakwitsa Machining (makamaka malo cholakwika).

4. Poyika zolakwika

Vuto la malo makamaka limaphatikizapo cholakwika cholozera molakwika ndi cholakwika chopanga chopanga cha awiriwo. Mukakonza chogwiritsira ntchito pa chida cha makina, zinthu zingapo za geometric pa workpiece ziyenera kusankhidwa ngati malo osungira panthawi yokonza. datum) sizigwirizana, cholakwika cha datum chidzachitika.

Malo oyika zida zogwirira ntchito ndi choyikapo choyika pamodzi zimapanga awiri oyimilira. Kusiyana kwakukulu kwa malo ogwirira ntchito komwe kumachitika chifukwa cha kupanga molakwika kwa malo awiriwo komanso kusiyana kofananira pakati pa awiriawiri oyika kumatchedwa cholakwika chopanga cholakwika cha malo awiriwo. Cholakwika chopanga cholakwika cha oyika awiriwo chidzangochitika pomwe njira yosinthira ikugwiritsidwa ntchito pokonza, ndipo sizichitika mu njira yodulira.

5. Kulakwitsa chifukwa cha mphamvu mapindikidwe dongosolo ndondomeko

Kuuma kwa workpiece: Ngati kuuma kwa workpiece mu dongosolo la ndondomeko kumakhala kochepa poyerekeza ndi zida zamakina, zida, ndi zida, pogwiritsira ntchito mphamvu yodula, kusinthika kwa workpiece chifukwa cha kuuma kosakwanira kudzakhudza kwambiri zolakwika za makina.

Kukhazikika kwa chida: Kukhazikika kwa chida chotembenukira ku cylindrical mozungulira (y) komwe kumapangidwa ndi kwakukulu kwambiri, ndipo kusinthika kwake kumatha kunyalanyazidwa. Pamene wotopetsa dzenje lamkati ndi m'mimba mwake yaing'ono, ndi rigidity wa chida kapamwamba ndi osauka kwambiri, ndi mapindikidwe mphamvu ya kapamwamba chida ali ndi chikoka chachikulu pa Machining kulondola dzenje.

Kukhazikika kwa zida zamakina: Zida zamakina zimapangidwa ndi magawo ambiri. Palibe njira yosavuta yowerengera kuuma kwa zida zamakina. Pakalipano, kuuma kwa zigawo za zida zamakina kumatsimikiziridwa makamaka ndi njira zoyesera. Zomwe zimakhudza kulimba kwa zida zamakina zimaphatikizira kukhudzidwa kwa kukhudzana kwapakatikati, kukhudzidwa kwa mikangano, kukopa kwa magawo otsika, komanso chikoka cha chilolezo.zida za aluminiyamu cnc Machining

6. Zolakwa chifukwa mapindikidwe matenthedwe a dongosolo ndondomeko

The mapindikidwe matenthedwe a dongosolo ndondomeko ali ndi chikoka chachikulu pa zolakwa Machining, makamaka Machining mwatsatanetsatane ndi lalikulu Machining, cholakwika Machining chifukwa mapindikidwe matenthedwe nthawi zina mlandu 50% ya okwana workpiece zolakwa.

7. Kusintha zolakwika

Mu ndondomeko iliyonse ya Machining, pali nthawizonse njira imodzi kapena ina kusintha dongosolo ndondomeko. Popeza kusinthaku sikungakhale kolondola kwenikweni, cholakwika chosintha chimachitika. Mu dongosolo la ndondomeko, kulondola kwapang'onopang'ono kwa malo ogwirira ntchito ndi chida cha makina opangira makina kumatsimikiziridwa ndi kusintha makina, chida, fixture kapena workpiece. Pamene kulondola koyambirira kwa zida zamakina, zida, zosintha ndi zosoweka zantchito zonse zimakwaniritsa zofunikira zaukadaulo popanda kuganizira zamphamvu, cholakwika chosintha chimakhala ndi gawo lalikulu pakulakwitsa kwa makina.

8. Cholakwika choyezera

Pamene gawolo likuyesedwa panthawi kapena pambuyo pokonza, kulondola kwa muyeso kumakhudzidwa mwachindunji ndi njira yoyezera, kulondola kwa chida choyezera, ndi workpiece ndi subjective ndi zolinga.

9. Kupsinjika kwamkati

Kupsinjika komwe kumakhala mkati mwa gawo popanda mphamvu yakunja kumatchedwa kupsinjika kwamkati. Kamodzi kupsinjika kwamkati kumapangidwa pa workpiece, chitsulo chogwirira ntchito chidzakhala chosakhazikika champhamvu kwambiri. Iwo mwachibadwa kusintha kwa khola mlingo otsika mphamvu, limodzi ndi mapindikidwe, kotero kuti workpiece amataya Machining ake oyambirira kulondola.
