Maitiro ekugadzira iyo machining kunyatso kudzora chirongwa

Tichagadzirisa nekuisa mhinduro kuchinetso chejometri saizi shiviriro mumachine mune zvina mativi: workpieces, maturusi, zvigadzirwa, uye muchina maturusi, uye isa mamwe mazano.
Inmechanical kugadzira, kubatana kunoumbwa nemuchina maturusi, zvigadziri, maturusi uye zvishandiso zvinodaidzwa kunzi maitiro maitiro. Mukuita kwekugadzirisa, nekuda kwekuvapo kwekukanganisa kwakasiyana-siyana kwechinyakare muhurongwa hwekuita, hukama chaihwo hwejometri pakati pebasa rekushandisa uye chishandiso chakaparadzwa, uye saizi yejometri iri kunze kwekushivirira. Kazhinji, zvikanganiso zvepakutanga zvinogona kuitika panguva yekugadzirisa zvakapatsanurwa kuita mhando mbiri, zvinoti, "static" zvikanganiso zvepakutanga zvine chekuita neyekutanga mamiriro ehurongwa hwehurongwa uye ne "simba" zvikanganiso zvepakutanga zvine chekuita nekugadzirisa maitiro. Izvi zvinotevera mazano ekugadzirisa dambudziko rekunze-kwe-kushivirira geometric zviyero mu machine zvikamukubva pamativi mana: ekushandira, maturusi, zvigadzirwa, uye maturusi mashini.

Workpiece
1) Iyo general musimboti wekugadzira inofanira kuteverwa, ndiko kuti, bhenji rekutanga, kozoti vamwe, kumeso kutanga, gomba kutanga, tenzi ipapo wechipiri, kukomba kutanga kwadaro kwakanaka, kwakakora uye kwakanaka kupatsanurwa.
2) Pamberi pekupedzisa danho reichi chiitiko, sunungura kumanikidza ndiro, nyatso kusunungura iyo yekumanikidza kushushikana, uye zvishoma zvinyoronyoro iyo yekushandira mushure mekuigadzirisazve. Kuti uve nechokwadi chekugadzirisa kuchengetedzeka uye kugadzirisa mhando, zvinokurudzirwa kuwana yakanakisa torque kukosha kwechiedza compaction kuburikidza nekuyedza ongororo uye kuita yenguva dzose torque kuomarara.
3) Iyo poindi yekuita kwesimba rekuchinjisa rinofanirwa kuve rakasimba poindi, uye poindi yekuita yakaremara nekuti haisi iyo chaiyo poindi. Pane mhinduro nhatu:

â ‘Oora iyo yekutanga yekunamatira kuita mbiri yakasimba-poindi, asi teerera kushandura Iyo kuteedzana kwekukochekera, kana zvichidikanwa, iyo yekushandira inoda kugadziriswazve.

âSeta kumusoro kweye clamping process shefu yeiyo workpiece, uye mushure mekunge maitirwo ese apedzwa, sarudza kuti wobvisa maitiro boss here zvichienderana nekuti zvinokanganisa here chikamu chebasa.

â ‘supports Zvitsigiro zvekubatsira zvinopihwa panzvimbo dzisina kusimba dzechimiro chekuumbirira (ona Mufananidzo 1). Dzimwe hydraulic anobatsira anotsigira pamusika uripo anogona kutowana "zero deformation" rutsigiro. Ku

Rutsigiro rwekubatsira 1

4) Onai kuti nzvimbo yekumisikidza yeiyo workpiece uye yechigadziro ine kugadzikana kwakanaka. Iyo flatness yekuzvitarisa-inoratidzwa muMufananidzo 2.

Kana iyo yekumisikidza ndege iri hombe, iyo yekumisikidza yekumisikidza pamusoro inogona kutsiviwa neyakavakirwa fomu kudzivirira iyo yekunamira inokanganisa deformation inokonzerwa neiyo workpiece uye hombe ndege yechigadziko;

kana kubhururuka kweiyo workpiece kukasakwanisika kuvimbiswa, ganda remhangura, mapepa ematehwe uye tambo dzeWarp, nezvimwewo, bata pasi pechinzvimbo uye wochitsimbirira kuti chigadziriswe.

Flatness kuzviongorora
5) Munguva yekugadzira michina, kucheka fluid kunoshandiswa kudzora kupisa munguva yekudzora iko kupisa kwekushambidza kweiyo workpiece.
6) Iyo yekuchembera kurapwa yakarongedzwa pamberi peiyo semi-yekupedzisa machining kuti isunungure zvachose kunetseka kwemukati kweiyo workpiece.
7) Kana uchinge watendeuka, kune matete-ane masvingo zvikamu, shandisa zvakapfava shaya kana kupatsanura makorari ekuchinjisa, kana kushandisa kumagumo kumeso kumanikidza pane kutenderera yakatenderera.

8) Panguva yekutendeuka, kudzoreredza deformation kugadzirisa kunoitwa zvinoenderana neiyo deformation, ndiko kuti, inoenderana deformation huwandu hwakatangira kugadziriswa munzira yakatarisana,

uye iyo yekudzosera deformation huwandu uye iyo deformation huwandu hunoregererana mushure mekugadziriswa kwapera.

9) Kana uchinge uchinge uchinge uchinge wakajairika workpieces, counterweight inofanirwa kuitiswa zvinoenderana nenzvimbo yepakati yemass yeiyo workpiece yekudzora iyo centrifugal simba.

Chishandiso chinhu

1) Usati wachera, unofinha uye unodzoreredza, kana paine hafu-yemadziro chimiro muchikamu chemuchina, iyo hafu-madziro chikamu chinofanira kubviswa kutanga;

kana iyo machining chikamu chiri chisina chinhu pamusoro, iyo isina chinhu pamusoro inofanira kuve-yakatarisana-yakatarisana kutanga kuona yunifomu simba panguva yekucheka.

2) Usati wagadzira, tarisa radial uye axial runout yechishandiso zvinoenderana nematanho akakodzera.
3) Vabati vezvishandiso vanorambidzwa kubhowa uye kukwenya, uye maturusi akakosha anoshandiswa kuchenesa maburi etaper echishina chokurukisa nguva dzose.
4) Chengetedza hurefu hwechishandiso, nepazvinogona napo kuona kuti chishandiso chine dhayamita yakakwana, kuona kuti chishandiso chakasimba.
5) Zvekushanda zvine hunyanzvi hwakanyanya kudikanwa, chishandiso chinofanira kuve chakadzikamisa musimba usati wagadziriswa.
6) Chinja kucheka parameter uye angles echishandiso, nezvimwewo, kudzora simba, kupisa uye kupfeka kwechishandiso panguva yekugadzirisa.
7) Shandisa anti-vibration uye anti-vibration maturusi akakosha.

Yechigarire chinhu
1) Natsiridza yekunamatira nzira yekudzivirira iyo yekuisa poindi yekumanikidza sikuru uye yekumashure rutsigiro poindi yekumanikidza ndiro kubva pakuva imwe pane yechigadziko uye imwe pane muchina turu yekudzivirira iyo yechigadziro kubva kukwevewa kumusoro neiyo yekumanikidza sikuru uye kukonzera zvakakomba deformation yechigadziko.

2) Chigadziko chinofanira kuve nekuomarara kwakaringana.

3) Kana chigadziriso chikatora mandrel yekumisikidza, uye iyo mandrel inopihwa tambo yekumanikidza, shinda inofanirwa kuve yepasi kuti ive nechokwadi chekutenderera kwetambo uye kumagumo ekumira pamusoro pemandrel.

4) Ita simba rekusimbisa revhisi pane chaiyo yekushandura zvigadziriso kudzora iyo centrifugal deformation yechigadziro painotenderera.

Muchina wekushandisa unoongorora uye unosimbisa chishandiso chemuchina zvinoenderana nemuchina wekugashira chishandisokururamisa zviyero, sekutarisa kutwasuka kwechimushini chishandiso chokurukisa uye chinoshandika, uye kufamba kweshinda.

Mashoko ekugumisa
1) Kana iyo yekushandira, kunyanya chigadzirwa chitsva, chave kusingashivirane mumatanho ejometri, tanga waona kuti rudzii rwekushomeka kuri kurikonzera, wozowana mhinduro yakakodzera zvinoenderana neyekuenderana deformation mhinduro.
2) Ongorora mashandisirwo emakomputa-anobatsira apera element element ongororo tekinoroji kuti aongorore deformation yeiyo process system pamberi, izvo zvinoita kuti kuenderere mberi kugadzirisa kwehurongwa hwekuita.
3) Mubasa rezuva nezuva, isu tinofanirwa kuve takapfupikisa mhinduro uye titore zvirevo kubva kune mumwe nemumwe, kuti tinatsiridze kugadzirisa chigadzirwa.
