Umsebenzi kanye nezinzuzo zesikhungo somshini we-axis amathathu:
TI-machining surface ephumelela kakhulu yesikhungo semishini eqondile (i-axis emithathu) ingaphezulu kuphela kwendawo yokusebenza, futhi isikhungo somshini esivundlile singaqedela kuphela umshini osemaceleni amane we-workpiece ngosizo lwetafula elijikelezayo.Njengamanje, izikhungo zokukhiqiza ezisezingeni eliphezulu zithuthuka ngendlela yokulawula ama-axis amahlanu, futhi umsebenzi wokusebenza ungacutshungulwa ngokucindezela okukodwa.Uma ifakwe isistimu ye-CNC ephezulu enokuxhumana kwama-eksisi amahlanu, ingakwazi futhi ukwenza imishini enembayo ezindaweni eziyinkimbinkimbi.
Kuyini ukwenziwa kwemishini ye-four-eksisi ngasikhathi sinye?
Okubizwa ngokuthi i-four-axis kanyekanye machining ngokuvamile yengeza i-eksisi ejikelezayo, ngokuvamile ebizwa ngokuthi i-eksisi yesine.Ithuluzi lomshini elijwayelekile linezimbazo ezintathu kuphela, okungukuthi, iplatifomu ye-workpiece ingahamba kwesokunxele nakwesokudla (i-axis engu-1), ngaphambili nangemuva (i-axis engu-2), kanye nekhanda lokuphotha (i-axis engu-3) lisetshenziselwa ukusika ama-workpieces.Ikhanda lokukhomba elizungezayo likagesi!Ngale ndlela, izimbobo ze-bevel zingakhonjiswa ngokuzenzakalelayo, futhi imiphetho e-beveled ingagaywa, njll., ngaphandle kokulahlekelwa ukunemba ngokucindezela kwesibili.
Izici zokuhlanganisa i-four-axis:
(1).Umshini wokuhlanganisa ama-axis amathathu awukwazi ukusetshenzwa noma udinga ukuboshelwa isikhathi eside kakhulu
(2).Thuthukisa ukunemba, ikhwalithi nokusebenza kahle kwezindawo ezikhululekile
(3).Umehluko phakathi kwe-four-eksisi kanye ne-axis emithathu;umehluko wama-eksisi amane kanye ne-axis emithathu ene-eksisi eyodwa yokuzungeza ngaphezulu.Ukusungulwa kwezixhumanisi ze-four-eksisi kanye nokumelwa kwekhodi:
Ukunqunywa kwe-axis engu-Z: isiqondiso se-eksisi sethuluzi lokuphotha lomshini noma isiqondiso esime mpo sethebula lokusebenza lokubopha ucezu lokusebenza yi-Z-eksisi.Ukunqunywa kwe-X-eksisi: indiza evundlile ehambisana nendawo yokufaka ucezu lokusebenza noma isiqondiso se-perpendicular ku-axis yokujikeleza ye-workpiece endizeni evundlile yi-X-eksisi.Ukuqondisa kude ne-axis yokuphotha kuyisiqondiso esihle.
Isikhungo semishini esine-eksisi emihlanu sihlukaniswe saba isikhungo semishini se-axis emihlanu esivundlile kanye nesikhungo semishini se-axis emihlanu esivundlile.Yiziphi izici zabo?
Isikhungo somshini se-axis emihlanu esime mpo
Kunezinhlobo ezimbili ze-axis ejikelezayo yalolu hlobo lwesikhungo somshini, enye i-axis ejikelezayo yetafula.
Isethi yetafula lokusebenza embhedeni ingazungeza i-X-eksisi, echazwa ngokuthi i-axis engu-A, futhi i-axis engu-A ngokuvamile inobubanzi obusebenzayo obungu-+30 degrees ukuya ku--120 degrees.Kukhona netafula elijikelezayo phakathi kwetafula lokusebenza, elizungeza i-axis engu-Z endaweni eboniswe esithombeni, echazwa ngokuthi i-C-eksisi, futhi i-axis ye-C izungeza ama-degree angu-360.Ngale ndlela, ngokuhlanganiswa kwe-axis engu-A kanye ne-axis ye-C, ucezu lokusebenza olumiswe etafuleni lungacutshungulwa yi-spindle eqondile ngaphandle kwendawo engezansi, ezinye izindawo ezinhlanu.Inani elincane lokuhlukanisa le-A-eksisi kanye ne-C-eksisi ngokuvamile lingama-degree angu-0.001, ukuze ucezu lokusebenza luhlukaniseke kunoma iyiphi i-engeli, futhi izindawo ezithambekile, izimbobo ezithambekile, njll. zingacutshungulwa.
Uma i-axis engu-A kanye ne-C-eksisi kuxhunywe nama-eksisi amathathu alayini we-XYZ, izindawo eziyinkimbinkimbi zendawo zingacutshungulwa.Yiqiniso, lokhu kudinga ukusekelwa kwezinhlelo ze-CNC eziphezulu, izinhlelo ze-servo kanye nesofthiwe.Izinzuzo zalolu hlelo ukuthi ukwakheka kwe-spindle kulula, ukuqina kwe-spindle kuhle kakhulu, futhi izindleko zokukhiqiza ziphansi kakhulu.
Kodwa ngokuvamile, i-worktable ayikwazi ukuklanywa enkulu kakhulu, futhi amandla okuthwala nawo mancane, ikakhulukazi lapho ukujikeleza kwe-A-eksisi kukhulu noma kulingana nama-degree angu-90, ukusika kwe-workpiece kuzoletha umzuzu omkhulu othwala umthwalo itafula lokusebenza.
Ingxenye engaphambili ye-shaft eyinhloko iyikhanda elijikelezayo, elingazungeza i-axis engu-Z 360 degrees futhi libe i-axis C.Ikhanda elijikelezayo liphinde libe ne-eksisi engu-A ekwazi ukuzungeza i-X eksisi, ngokuvamile engaphezu kwamadigri angu-±90, ukuze kuzuzwe umsebenzi ofanayo nongenhla.Inzuzo yale ndlela yokusetha ukuthi ukucutshungulwa kokuphotha kuvumelana nezimo kakhulu, futhi ithebula lokusebenza lingaklanywa ukuthi libe likhulu kakhulu.Umzimba omkhulu wendiza yabagibeli kanye nebhokisi elikhulu lenjini lingacutshungulwa kulolu hlobo lwesikhungo somshini.
Izici zesikhungo semishini ye-axis emihlanu evundlile
Kukhona futhi izindlela ezimbili ze-axis ejikelezayo yalolu hlobo lwesikhungo somshini.Enye ukuthi i-spindle evundlile iyashwibeka njenge-axis ejikelezayo, kanye ne-axis ejikelezayo yetafula lokusebenza ukuze kuzuzwe ukucutshungulwa kokuxhuma kwama-eksisi amahlanu.Le ndlela yokusetha ilula futhi iyavumelana nezimo.Uma i-spindle idinga ukuguqulwa iqonde futhi ivundlile, ithebula lokusebenza lingavele limiswe njengesikhungo somshini wama-eksisi amathathu esinokuguqulwa okuqondile nokuvundlile kuphela ngokufaka inkomba nokubeka indawo.Ukuguqulwa okuqondile nokuvundlile kweshafti eyinhloko kubambisana nokukhonjwa kwethebula lokusebenza ukuze kubonakale ukucutshungulwa kwe-pentahedral ye-workpiece, okunciphisa izindleko zokukhiqiza futhi kusebenza kakhulu.Izimbazo ze-CNC nazo zingasethwa kuthebula lokusebenzela, elinenani lenkomba elincane elingu-0.001 degrees, kodwa ngaphandle kokuxhumana, liba isikhungo semishini ye-four-axis sokuguqulwa okuqondile nokuvundlile, ukujwayelana nezidingo ezahlukene zokucubungula, futhi intengo iyancintisana kakhulu.
Enye i-axis yendabuko ye-rotary yetafula lokusebenza.I-axis yethebula lokusebenza isethwe embhedeni ngokuvamile inebanga lokusebenza kusuka ku-+20 degrees kuya ku-100 degrees.Kukhona netafula elijikelezayo i-axis engu-B phakathi nendawo yokusebenza, futhi i-axis ye-B ingazungeza ama-degree angama-360 kuzo zombili izinkomba.Lesi sikhungo semishini se-axis emihlanu esivundlile sinezici zokuxhuma ezingcono kunendlela yokuqala, futhi ngokuvamile sisetshenziselwa ukucubungula izindawo eziyinkimbinkimbi ezigobile zama-impellers amakhulu.I-axis ejikelezayo ingabuye ifakwe impendulo eyisiyingi, futhi ukunemba kwenkomba kungafinyelela imizuzwana embalwa.Yiqiniso, ukwakheka kwale axis ejikelezayo kuyinkimbinkimbi futhi kuyabiza.
Iningi lezikhungo zemishini zingaklanywa ukushintshanisa amatafula okusebenzela aphindwe kabili.Lapho ithebula lokusebenza elilodwa lisebenza endaweni yokucubungula, elinye ithebula lokusebenza lishintsha ucezu lokusebenza ngaphandle kwendawo yokucubungula ukuze lilungiselele ukucutshungulwa kocezu lokusebenza olulandelayo.Isikhathi sokushintshana kwe-worktable sincike kuthebula lokusebenza.Usayizi, kusukela kumasekhondi ambalwa ukuya emashumini amasekhondi ukuze uqedele.
