Kutheni le nto i-CNC-Machined Excavator i-Upper Frame Pass yokuHlola kodwa iSilele iNdibano yokuBetha iSlewing? 

Impendulo ethe ngqo: I-excavator ephezulu eyenziwe ngoomatshini be-CNC inokudlula uhlolo lwe-dimensional kodwa ingaphumeleli indibano ethwele i-slewing-bearing xa ukuhlolwa kungavelisi imeko yokwenyani yokunyuka. Izizathu eziqhelekileyo ziquka ukunyuswa kobuso obuphezulu phantsi kwemeko yenkxaso engalunganga, iindawo eziphezulu zendawo, impazamo yendawo ye-bolt-hole, ukungahambelani kwe-datum-axis, ukuphazamiseka kwe-weld, ukukhutshwa koxinzelelo olwenziwa ngomatshini, ukungcoliswa komphezulu, okanye ukuguqulwa kwefreyimu ngexesha lokubhobhoza kunye nokuthutha.

Le ngxaki ibalulekile kwii-OEM zokwemba, abavelisi boomatshini bokwakha, abathengi becandelo lolwakhiwo, iiplanti zendibano, kunye neenjineli ezisemgangathweni ezifumana iifreyimu ezidityanisiweyo kunye nezomatshini aphezulu. Ingxelo ingabonisa ukuba yonke imilinganiselo ehloliweyo ingaphakathi kokunyamezela komzobo wayo, ukanti ibhodi yokubulala ayihlali ngokulinganayo, imingxuma yebholithi ayilungelelanisi ngokukhululekileyo, iibholithi zitsalela ibheringi kwindawo, okanye ukujikeleziswa kuba nzima emva kokudityaniswa. Isikhewu siqhele ukuba "ukuhlolwa ngokuchasene nokuhlolwa." Ingaba ngaba ukuhlolwa kulawule ujongano olufanayo olusebenzayo olubonwa yibhere ngexesha lofakelo.

Izibonelelo ze-WLD oomatshini bokwakha amacandelo esakhiwo, kuquka i Excavator Upper Frame Slewing Platform. Ukuthengwa kwe-OEM, isicwangciso sokukhululwa kufuneka sidibanise imeko ye-welding, i-CNC machining, isicwangciso se-datum, ukuhlolwa kwe-bearing-interface, ukuphatha, kunye nobungqina bendibano kunokuphatha inkqubo nganye njengenyathelo elizimeleyo lokupasa / lokungaphumeleli.

Kuthetha ukuthini ukuthi “Ukuphumelela ukuhlolwa kodwa kusilele iNdibano”?

Ngaphambi kohlalutyo lwengcambu, umthengi kufuneka achaze ukusilela kwendibano ngokuchanekileyo. “Ukuthwala akungeni” kunokuchaza iimeko ezininzi ezahlukahlukeneyo, nganye isalatha kwingxaki yolawulo eyahlukileyo.

Indawo yamava kwishishini: Ibinzana elithi "yonke imilinganiselo edlulisiweyo" bubungqina obubuthathaka de umthengi azi ukuba yeyiphi imilinganiselo ehlolwe, ukusuka kwiyiphi i-datums, phantsi kweyiphi imeko yenkxaso, kwaye ingaba i-interface yokuthwala yayilinganiswa njengendlela yokusebenza.

Kutheni le nto i-Mounting-Face Flatness inokudlula kumatshini kodwa usilele phantsi kweeMeko zeNdibano?

Isakhelo esikhulu esidityanisiweyo esingaphezulu asiyobloko engqongqo ngokungenasiphelo. Ijometri yayo elinganisiweyo inokutshintsha kunye neendawo zenkxaso, i-clamping, uxinzelelo olushiyekileyo, ukuphatha, kunye nolandelelwano apho izixhobo zomatshini zikhululwa. Ubuso obunyukayo obubonakala buvunyiwe ngelixa isakhelo sithintelwe kwitafile yomatshini ayinakuhlala ikwimeko efanayo xa inxalenye ibekwe kwi-OEM yendibano yendibano.

Oku kubaluleke kakhulu kwimigangatho yokukhwela i-slewing-bearing kuba ukuthwala kuxhomekeke kwinkxaso ebanzi, eqhubekayo evela kwisakhiwo somlingane. Iincopho zasekuhlaleni, utshintsho olukhawulezileyo, okanye amacandelo angaxhaswanga anganyanzela umsesane wokuthwala ukuba uhambelane xa iibholiti ziqinisiwe.

Abathengi ke ngoko kufuneka bachaze:

• indlela isakhelo esixhaswa ngayo ngexesha lokuhlolwa kojongano lokugqibela;
• ingaba imeko yokuhlola imele imeko yendibano;
• ubuso obunjani okanye idatum eseka inqwelomoya yokukhwela;
• ingaba imephu egcweleyo yomphezulu ojikelezileyo iyafuneka kunokuba kujongwe amanqaku ambalwa;
• indlela isakhelo esikhululwa ngayo kwizixhobo zoomatshini ngaphambi komlinganiselo wokugqibela;
• ingaba ukuhlolwa kwakhona kuyafuneka emva kokuphinda kusetyenzwe ngokutsha okanye kuthuthwe.

Indawo yamava kwishishini: Ukulinganisa amanqaku amaninzi kuphela kwisihlalo esikhulu seringi kunokuphosa indawo ephakamileyo yendawo emxinwa. Ukuthwala kungabhuloka okanye kunyanzeliswe kulo lonke elo candelo naxa umndilili wenqwelomoya ukhangeleka wamkelekile.

Inokuthi i-Weld Distortion ivele njani emva koMatshini we-CNC?

Ukutshiza kunokwenza i-weldment egqwethiweyo ilungile kwinqanaba elinye ngaphandle kokuphelisa utyekelo olusisiseko lokuhamba. Ukuba i-weldment iqulethe uxinzelelo olushiyekileyo okanye aluzange lufikelele kwisimo esizinzile ngaphambi kokulungiswa kokugqibela, ukukhutshwa kwezinto eziphathekayo kunye nokukhululwa kwesigxina kunokutshintsha isimo sokugqibela.

Ingxaki asikuko ukuba ukwenziwa kwe-CNC akuchanekanga. Ingxaki kukusebenzisa i-machining yokugqibela njengendlela yodwa yolungiso lwesakhiwo esidityanisiweyo esingazinzanga. Ukuba isakhelo esinye sifikelela kwinqwelo-moya ekujoliswe kuyo kuphela ngenxa yokuba isixa esikhulu sezinto eziphathekayo sisusiwe kwicandelo elinye, inxalenye inokuba nomda omncinci wokusasazwa kwakhona koxinzelelo okanye ukulayisha indibano.

I-OEM kufuneka ijonge indlela epheleleyo ukusuka kwimveliso ukuya kumatshini:

• ukulandelelana kwe-weld kunye neqhinga lokuthintela;
• iitshekhi zedimensional eziphakathi;
• imeko ye weldment phambi machining rough;
• isibonelelo somatshini kwisitulo sokuthwala;

Indawo yamava kwishishini: Umphezulu womatshini wokugqibela unokuba sicaba ngelixa isakhiwo esijikelezileyo sihlala singazinzile. Ukulungelelaniswa kwemveliso kufuna ubungqina bokuba isakhelo esidibeneyo sifikelela kwi-machining kwimeko ephindaphindiweyo, kungekhona nje ukuba inxalenye enye inokunqunyulwa emva kokunyamezela.

Kutheni le nto i-Bolt-Hole Position kunye ne-Bearing-Axis Datums kulula ukuyifunda kakubi?

Isangqa sebholithi singadlula ujongo olulula lomngxuma ukuya kumngxunya xa lusashenxiswa, lujikeleziswa, okanye i-eccentric inxulumene ne-axis yokujula esebenzayo. Umbuzo obalulekileyo ayikokuba isithuba semingxuma esecaleni sijongeka sichanekile; kukuba ipateni epheleleyo yomngxuma ibekwe ngokuchanekileyo xa kuthelekiswa nesihlalo sokuthwala kunye needatum ezichaziweyo ze-OEM.

Izikhewu zenkcazo eziqhelekileyo ziquka:

• ipateni yomngxuma elawulwa kwiziko lokwenziwa kwempahla endaweni ye-axis ethwele ngoomatshini;
• uhlolo olwahlukileyo lwesithuba somngxunya ngaphandle kobudlelwane bendawo yokwenyani kwidatum yokunyuswa;
• ukuthwala-isihlalo ububanzi kunye nebholithi isangqa kulinganiswa useto ezahlukeneyo;
• ingacacanga i-zero-engile okanye ireferensi yoqhelaniso;
• uhlaziyo lokuzoba olutshintsha umngxuma okanye iireferensi zedatum ngaphandle kokuhlaziya inkqubo yokuhlola.

I-WLD ikwadwelisa i Excavator Lower Isakhelo, eyinxalenye yolwakhiwo-omatshini bolwakhiwo-icandelo leqela. Ujongano lwefreyimu ephezulu nasezantsi kusafuneka ihlolwe ngokuchasene nemizobo elawulwayo; ubukho beentsapho zemveliso ezihambelanayo akuseki ukutshintshiselana okanye ukunyamezelana kwendibano.

Ngaba iMeko yoMphezulu inokubangela ukusilela kweNdibano nokuba iJometry ichanekile?

Ewe. Isihlalo esine-slewing-bearing kufuneka siphathwe njengendawo yokudibanisa esebenzayo. I-weld spatter, i-peint build-up, i-burrs, i-chips machining, i-dents, iimveliso zokugqwala, i-adhesive residue, okanye ezinye izitenxo zendawo zingadala indawo ephezulu etshintsha indlela i-ring ring exhaswa ngayo xa iibholiti ziqinisiwe.

Umthengi kufuneka achaze ukuba ngubani onoxanduva lokucocwa kokugqibela kunye nokukhusela ubuso obuxhonyiweyo, ukuba yeyiphi imiphezulu enokuthi igqunywe, indlela ubuso bomatshini obukhuselwa ngayo ngexesha lothutho, kwaye loluphi uhlolo lokufumana ekufuneka lugqitywe ngaphambi kokuba kufakwe ibherethi.

Indawo yamava kwishishini: Isakhelo sinokushiya ukuthotyelwa kokuhlolwa kokugqibela kwaye sifike kwindibano kunye nesihlalo sokuthwala esonakalisiweyo ngenxa yokuba ubuso bomatshini busetyenziswe njengendawo yokudibanisa amatyathanga, iibhloko, okanye izithintelo zokuthutha.

Kutheni iBolting inokujika iFinethi eLungileyo ibe yiBhere eTight?

Ukuba ukuthwala kuqala kuhleli kwisakhelo kodwa ukujikeleza kuba nzima emva kwebholting, inkqubo yendibano inokuthi ibonakalise inkxaso okanye ingxaki yokuqina. Ukuqinisa “akupheleli nje ekubambeni igxalaba.” Inyanzelisa i-ring ring kunye ne-companian structure ibe yimeko ekwabelwana ngayo.

Ukuba ubuso obunyukayo bunenkxaso engalinganiyo okanye isakhelo siguquguquka kakhulu phantsi komthwalo we-bolt, ukuthwala kunokuphazamiseka emva kokuqina. Kungenxa yoko le nto umthengi kufuneka ahlule iindawo zokukhangela ezintathu:

1. ukuthwala izihlalo ngokukhululekileyo phambi kokuba iibholithi ziqiniswe;
2. iibholiti zingena ngaphandle kokuzisebenzisa ukutsala ibhereyi kukulungelelaniswa;
3. ukuthwala okudityanisiweyo kuhlala ngaphakathi kokujikeleza okufunekayo kwe-OEM, ukulungelelaniswa, kunye nokukhangela i-gear-interface emva kwenkqubo ekhankanyiweyo yokuqinisa.

Ukulayishwa kwangaphambili kwebholithi, ukulandelelana kokuqinisa, ukuthwala umda we-flatness, kunye nemfuneko ye-gear-backlash kufuneka ivele kwi-bearing evunyiweyo kunye namaxwebhu omatshini. Akufunekanga ukuba zenziwe ngumthengisi wefreyimu ephezulu okanye zikotshwe kwenye imodeli ye-excavator.

Kutheni le nto imeko yeNkxaso yoHlolo ibaluleke kangaka?

Isakhelo esinzima esingaphezulu sinokulinganiswa kwitafile yomatshini, iitendi zokuhlola, inkxaso yezothutho, okanye indibano ye-OEM. Loo miqathango yenkxaso inokulayisha isakhiwo ngokwahlukileyo. Ukuba umzobo uchaza ukuhlolwa kwindawo ekhululekileyo okanye kwiinkxaso zereferensi ezikhankanyiweyo, bobabini umthengisi kunye nomthengi kufuneka basebenzise loo meko ngokungaguqukiyo.

Ngaphandle koko, iingxelo ezimbini zokuhlola zinokungavumelani nokuba zombini iinkqubo zokulinganisa zisebenza ngokuchanekileyo. Ingxabano ibangelwa kukuba inxalenye ilinganiswa kwiindawo ezimbini ezahlukeneyo ngoomatshini.

Indawo yamava kwishishini: Xa isakhelo esidityanisiweyo esikhulu "sitshintsha ubungakanani" phakathi komnikezeli kunye nomthengi, isheke yokuqala kufuneka ibe ngamanqaku enkxaso kunye nemeko yokubambelela phambi kokucinga ukuba inkqubo yokulinganisa ayilunganga.

Imeko: I-Bearing ilingana neCandelo elinye kodwa iiBolts zokugqibela aziyi kungena

Imeko emeleyo - hayi ityala lomthengi we-WLD.

Imvelaphi yeShishini: I-excavator ye-OEM ifumana isakhelo esiphezulu se-CNC. Ingxelo yokugqibela enemilinganiselo ibonisa inqwelo-moya efakwe ngoomatshini, ukuvulwa kweziko, kunye nemilinganiselo yomngxuma webholithi njengoko yamkelwe.

Ingxaki: Ngexesha lokufakwa kwe-slewing-bearing, ezininzi iibholiti zingena ngokukhululekile, kodwa icandelo lokugqibela lifuna ukuba ukuthwala kuguqulwe kwaye iibholiti ezininzi kufuneka zinyanzeliswe ukulungelelaniswa. Emva kokuqiniswa, ukujikeleza kubonakala kuqina ngakumbi kunexesha lokujonga ukubekwa kokuqala.

Unobangela: Ukuhlolwa komthengisi kuhlolisise isithuba semingxuma yendawo kunye neendawo ezininzi zokunyuka kobuso kodwa akuzange kuqinisekise ipateni epheleleyo yebholithi enxulumene ne-axis esebenza phantsi kwemeko yenkxaso yendibano yemveliso. Ubuso bendawo indawo ephezulu kunye nokutshintsha kwepateni encinci idibanisa ukuphazamisa ukuthwala xa iibholiti ziqinisiwe.

Isisombululo: I-OEM kunye nomboneleli baphinde bamisele iskimu sedatum elawulwayo, imephu isihlalo esipheleleyo sokuthwala, uqinisekise isangqa se-bolt ngokubhekiselele kwi-axis efanayo yokusebenza, ukuhlaziya iimeko zenkxaso, kwaye wenze i-free-fit bearing / fixture check ngaphambi kokuba ibhetshi elandelayo ikhululwe. Ingxelo yokuhlola ihlaziywa ukuseta irekhodi, iidatum, kunye nobudlelwane obubalulekileyo bonxibelelwano.

Ixabiso leSigqibo soMthengi: Umthengi uyakuphepha ukuphatha uphawu njengengxaki yokuthwala kwaye aguqule ukungaphumeleli kwendibano ibe yinkqubo yojongano olulinganisekayo oluphezulu lwesakhelo solawulo lwemveliso ephindayo.
