Njengamanje, imishini yokuqopha kancane kancane isiphenduke amathuluzi abalulekile ezimbonini ezihlukahlukene. Ngokuthuthukiswa nokusebenzisa ubuchwepheshe be-CNC obuhlanganiswe nezilawuli ezisebenza kahle kakhulu eziguquguqukayo kanye nemishini ye-servo drive ezimbonini ezahlukahlukene zokukhiqiza, imishini yokuqopha ye-CNC isibe ukucushwa okujwayelekile embonini yanamuhla yokubaza. Isistimu yokudlulisa eyinhloko yamathuluzi omshini wokuqopha we-CNC ngokuvamile isebenzisa isivinini esiguquguqukayo esingenasinyathelo. Amasistimu wejubane eliguquguqukayo lezinto ezingaphili ahlanganisa ikakhulukazi izinhlobo ezimbili: amasistimu wokuphotha ahlukahlukene kanye nezinhlelo zokuphotha ze-servo. Ngenxa yezindleko eziphakeme zokushayela amafrikhwensi ahlukahlukene, asetshenziswa kakhulu kumathuluzi omshini. Uhlelo lokuphotha luyingxenye ebalulekile yomshini wokuqopha we-CNC, futhi ukusebenza kwawo kunomthelela obalulekile ekusebenzeni okuphelele komshini wokuqopha we-CNC. Njengenhliziyo yesistimu yokuphotha, isiguquli semvamisa siyisici esibalulekile esibalulekile. Lesi sihloko sethula ukusetshenziswa kwesiguquli sefrikhwensi yochungechunge lwe-Dongli Kechuang CT100 kusistimu ye-spindle drive yomshini wokuqopha we-CNC.
Isingeniso Sesimiso Sokulawula Ugesi Womshini Wokubaza we-CNC
Ukwakhiwa kwesistimu yokulawula kagesi yomshini wokuqopha we-CNC
Isistimu yokulawula kagesi yomshini wokuqopha we-CNC ikakhulukazi iqukethe izingxenye ezintathu: isistimu yokulawula izinombolo ye-CNC, isistimu yokumisa i-spindle, kanye nesistimu yokujikeleza kokuphotha. Imisebenzi yengxenye ngayinye imi kanje:
Isistimu yokulawula izinombolo ye-CNC: Idizayini yephethini nesakhiwo kwenziwa ngesofthiwe ekhethekile yokuqopha emiswe kukhompuyutha. Imininingwane yedizayini nesakhiwo idluliselwa kusilawuli somshini wokuqopha ngekhompyutha, bese isilawuli siguqula lolu lwazi lube amasignali okushaya kwenhliziyo angashayela amamotho anyathelayo noma ama-servo motors. Isistimu yokumisa iqedela umklamo kanye nemodeli yephethini yesakhiwo ngokuthola amasignali we-pulse ukuze abekwe.
Isistimu yokumisa ye-Servo: Izimbazo ezintathu eziqonde komunye nomunye zingasetshenziswa ukuqedela ukuma kwe-eksisi emithathu endaweni enezinhlangothi ezintathu. Ngakho-ke, amasethi amathathu wezinhlelo zokubeka i-servo athola amasignali we-pulse kusuka kusistimu yokulawula izinombolo ye-CNC ukuze enze ukubaza nokubeka ithuluzi kuma-ax X, Y, kanye no-Z, ngaleyo ndlela aqedele noma iyiphi imodeli yesampula endaweni enezinhlangothi ezintathu.
Isistimu yokwenza ama-spindle machining: Isistimu yokubeka i-servo iqeda isampula yemodeli yephethini, futhi umsebenzi wokubaza ohambisanayo udinga ukuqedelwa endaweni yokusampula ehambisanayo ukuze kuqedelwe ukuhlelwa kwesistimu yokulawula izinombolo ye-CNC yezinto ezibaziweyo. Ngakho-ke, ukujikeleza kwe-spindle ngesivinini esikhulu kuyadingeka ukuze kuqedelwe umsebenzi wokubaza. Izinto zokuqopha ezihlukene kanye nokunemba okuhlukene okuqoshiwe kudinga uhlelo olujikelezayo lube nomsebenzi wokulawula isivinini oguquguqukayo.
Izidingo zokulawula ze-frequency converter yomshini wokubaza uhlelo lokucubungula i-spindle
Izidingo zokusebenza zesistimu yeziguquli zefrikhwensi
(1) Ibanga lejubane libanzi, futhi isivinini sokusebenza ngokuvamile siphakathi kuka-0-24000r/min.
(2) Ukushintshashintsha kwesivinini okuncane kulo lonke uhla lwesivinini;
(3) I-torque yejubane eliphansi inkulu, engaqinisekisa ukusika ngesivinini esiphansi;
(4) Zama ukugcina isikhathi sokusheshisa nesokunciphisa sibe sifushane ngangokunokwenzeka.
Izidingo zokusebenza zesistimu zesiguquli sefrikhwensi
(1) Imodi yokulawula ikhethwa njengokulawula kwe-V/F ukuze ivumelane nezidingo zokulawula ububanzi besivinini, izakhiwo ezinozibuthe ezibuthakathaka, ukuzinza okuhle kokushayela, njll.
(2) Isitobhi sokuqala sokulawula isiphetho, sibona isitobhi sokuqala esikude kanye nokuya phambili/ukuhlehla;
(3) Imvamisa yokusebenza ye-analog, ekwazi ukwamukela ukuphuma kwamandla kagesi angu-0-10VDC;
(4) Ibanga lejubane liyi-0-2400r/min, futhi imvamisa yokusebenza yesiguquli semvamisa iguqulwa ibe ngu-0-400Hz (injini yesibili enesivinini esikhulu);
(5) Isikhathi sokusheshisa kanye nokunciphisa isikhathi sifushane, ngokuvamile phakathi kwamasekhondi angu-3-5. Ngenxa yejubane eliphezulu lokusebenza, i-converter frequency neyunithi yokubhuleka iyadingeka;
(6) Kudingeka isignali yokuphuma kwephutha ukuze kuqinisekiswe ukuvikelwa ngesikhathi kwesistimu uma kwenzeka ukwehluleka kokuphotha; Isignali yokusetha kabusha iphutha iyadingeka ukuze kuqinisekiswe ukusetha kabusha kwesilawuli kude futhi uqale kabusha lapho iphutha selixazululiwe.
Indlela yokumisa isiqalo yesiguquli sefrikhwensi iyisitobhi sokuqala sokugcina, okusho ukuthi amatheminali okufakwayo kwedijithali yesistimu yokulawula izinombolo ye-CNC asetshenziselwa ukunikeza imiyalo ye-DI1/DI2 kusiguquli sefrikhwensi ukuze kuzuzwe ukuma kokuqala nokuya phambili/ukuhlehla kwenjini yokuphotha. Uma kucatshangelwa ukuthi ukubhuleka ngokushesha kungase kudingeke uma uhlelo lwezimo eziphuthumayo luhluleka ukugwema ukulimala komshini, umsebenzi wokumisa izimo eziphuthumayo uqaliswa nge-DI3 njengetheminali. Isignali yephutha yesiguquli sefrikhwensi iphuma ngetheminali yokudlulisela imvamisa ehlelekayo, futhi isistimu ithola isignali yephutha ukugwema ukulimala komshini okubangelwa ukungasebenzisi kahle lapho isiguquli sefrikhwensi sihluleka. Ngemuva kokuthi iphutha selisuliwe, ilokhi yephutha ingakhululwa ngetheminali yokusetha kabusha. Indlela yokulawula isivinini sesistimu ingukuguqulwa kwedijithali ukuya kwe-analogi yohlelo lokulawula izinombolo. Isiguquli sefrikhwensi sithola isignali ye-voltage engu-0-10V kusuka ohlelweni lokulawula izinombolo njengesignali yefrikhwensi futhi silungisa ngokuzenzakalelayo isivinini sokuqopha.
