I-Linear Stepper Actuator

I-Linear stepper actuator iyidivayisi evulekile-yokulawula i-loop ehambisana ngokuqondile ne-stepper motor enomshini wokudlulisa womugqa, futhi ifinyelela ukunyakaza kwendawo ehlukene ngokulawula isignali ye-pulse. I-linear stepper actuator iyisisetshenziswa se-electromechanical esiguqula amasignali we-pulse kagesi abe indawo eqondile yomugqa, ehlanganisa izici zokushayela ze-stepper motor enamandla okukhipha umugqa. Isetshenziswa kakhulu ezimeni ezidinga ukuma okunembayo kodwa ezingadingi ukulawula iluphu{3}}okuvaliwe.

Izici eziyinhloko ze-Linear stepper actuator ziyisakhiwo esilula, izindleko eziphansi, kanye nokuma ngaphandle kwempendulo, zilungele izimo ezizenzakalelayo ezinokunemba okuphansi kuya kokuphakathi nomthwalo ophansi kuya omaphakathi, njengokuphrinta kwe-3D, okokusebenza kwezokwelapha, ukupakisha okuzenzakalelayo, njll.

Iisimiso sokusebenzakweI-Linear stepper actuator isuselwe esinyathelweni-nge{1}}ngezinyathelo zokuzungeza izici zamamotho anyathelayo:

isilawuli sithumela amasignali e-pulse ukushayela injini enyathelayo ukuze ijikelezise isinyathelo ngesinyathelo nge-engeli engaguquki (efana ne-1.8℃/step), bese iguqula ukunyakaza okuzungezayo kube ukususwa komugqa ngokusebenzisa izindlela zokudlulisela ezifana nezikulufu namagiya. Ku-pulse ngayinye yokokufaka, i-actuator ihambisa ibanga lesinyathelo esingashintshi (imvamisa ngama-micrometer), futhi ukususwa kuhambisana nenani lama-pulses. Ingakwazi ukufinyelela{3}}ukulawula okunembile kwe-loop ngaphandle kwezinzwa zempendulo futhi inesakhiwo esilula.

Ngokwesakhiwo, i-actuator ye-stepper eqondile yakhiwa ikakhulukazi izingxenye ezintathu:

iyunithi yokushayela (i-stepper motor kanye nesekethe yokushayela), ingxenye yokudlulisela (isikulufu sebhola noma isikulufu se-trapezoidal, esinesibopho sokuguqula ukuzungeza kube ukunyakaza okulandelanayo), kanye nesistimu eqondisayo (amabheringi alayini noma ama-rails aqondisayo, aqinisekisa ukunyakaza okushelelayo). Amanye amamodeli ahlanganisa ukushintsha komkhawulo ukuze avimbele ukusebenza kokudlula futhi enze ukwakheka kwesistimu kube lula.

Uhlelo lokusebenza lugxile kuzimo zokubeka ukunemba okuphansi kuya kokumaphakathi:

Isiphakeli se-nozzle samaphrinta e-3D, idrayivu esebenzayo esebenzayo yamathuluzi omshini we-CNC emincane, ukudluliswa kwesampula kwempahla yaselabhorethri ezishintshayo, ukulawula umthamo wamadivayisi wezokwelapha (njengamaphampu afakwayo), i-lens egxile ezintweni zokuphepha, njll. Izinzuzo zayo ziphansi kwezindleko zayo uma kuqhathaniswa namasistimu e-servo, ukulawula okulula, asikho isidingo se-loop circuits eyinkimbinkimbi evaliwe{2}}, futhi akukho vibration phakathi{3}} I-Linear stepper actuator ifaneleka ezimo ezinyakazayo ezinemithwalo elula nokuphindaphinda okuphezulu. Ukunemba kwesinyathelo ngokuvamile kungafinyelela ku-± 0.01mm, kuhlangatshezwane nezidingo zezinto zokusebenza eziningi ezishintshayo ezincane neziphakathi{7}}nosayizi.

Kunomehluko omkhulu phakathi kwe-linear stepper motor actuators kanye ne-linear servo motor actuators ngokwezindlela zokulawula, izici zokusebenza, kanye nezimo ezisebenzayo. Umehluko othize umi kanje:

1. Izimiso zokulawula ezihlukene

I-Linear stepper motor actuator: ithatha i-loop control evulekile-, ishayela injini ukuthi ijikelezise (noma ihambe emgqeni oqondile) ebangeni lesinyathelo esinqunyiwe ngokwamukela amasignali okushaya kwenhliziyo, futhi ukususwa kuhambisana ngokuqinile nenani lama-pulses, ngaphandle kwesidingo sezinzwa zempendulo yendawo. Inqobo nje uma isignali yokushaya kwenhliziyo inembile, ukunyakaza okusethiwe kungafinyelelwa, kodwa ayikwazi ukuzwa ukuthi ukuma kwangempela kuyaphambuka yini emyalezweni.

I-Linear servo motor actuator: isebenzisa-isilawuli se-loop esivaliwe, ihlanganisa izinzwa zendawo (njenge-grating rula, isifaki khodi), futhi ibuyisela indawo yangempela nesivinini kusilawuli ngesikhathi sangempela. Isilawuli siqhathanisa inani lomyalo nevelu yempendulo, silungisa okukhiphayo ngokushintshashintshayo ukuze siqinisekise ukunemba kokunyakaza, futhi singalungisa ukuchezuka okubangelwa izinguquko zomthwalo namaphutha okusebenza.

2. Ukunemba okuhlukile namandla okuphatha amaphutha

I-Linear stepper motor actuator: ukunemba kuncike ekuvumelaneni kwe-engeli yesinyathelo (noma isinyathelo esiwumugqa), ngaphandle kwamandla okulungisa iphutha. Uma umthwalo mkhulu kakhulu futhi imvamisa yokushaya kwenhliziyo iphezulu kakhulu, kungase kube khona ukulahleka kwesinyathelo (ukususwa kwangempela kuncane kunokusuka okuyaliwe), futhi amaphutha azonqwabelana. Ukunemba kwesinyathelo kuvame ukuba ngu-± 0.01mm 0.1mm.

I-Linear servo motor actuator: Ukulungisa iphutha lesikhathi sangempela ngempendulo-yeluphu evaliwe, ikhono eliqinile lokulwa{1}}nokuphazamiseka, ukunemba okuphezulu kokuphindaphinda (kufika ku-± 0.001mm 0.01mm), ngisho noma kukhona ukuguquguquka komthwalo noma ukuphazamiseka kwangaphandle, ingabuyiselwa endaweni eyalwe ngayo ngokulungiswa ngaphandle kwephutha elikhulayo.

3. Isivinini esihlukile kanye nokusabela okuguquguqukayo

I-Linear stepper motor actuator: ukusebenza okuzinzile okuphansi-kwesivinini, kodwa kujwayeleke ukudlidliza kanye nokulahlekelwa isinyathelo ngesikhathi-sokusebenza okuphezulu, futhi i-torque ephumayo iyancipha ngesivinini esikhulayo (kunengozi "yokulahlekelwa yisinyathelo"), elungele izimo zokunyakaza eziphansi-nezikhawu.

I-Linear servo motor actuator: Ngokusabela okuphezulu-kwejubane eliphezulu kanye nokulawula iluphu{1}}okuvaliwe, ingakwazi ukugcina okukhiphayo okuzinzile ebangeni elibanzi lesivinini. Izinqubo zokusheshisa nokuhlehlisa zishelela, okuyenza ifaneleke izimo ezidinga ukuma ngokushesha kokuqala noma ukunyakaza{3}}kwesivinini esiqhubekayo.

4. Umthamo wokulayisha ohlukile kanye nezici ze-torque

I-Linear stepper motor actuator: I-torque ephumayo (noma i-thrust) iyancipha ngesivinini esikhulayo. Ngesivinini esiphansi, i-torque inkulu, kodwa ngesivinini esikhulu, ijwayele ukulayisha kakhulu ngaphansi kwemithwalo esindayo. Ifanele imithwalo elula (imvamisa ingaphansi kuka-500N) kanye nezimo eziphansi ze-inertia.

I-Linear servo motor actuator: Ngokuvala-loop control, amandla okukhiphayo angalungiswa ngokuya ngezinguquko zokulayisha. Inamandla aqinile-ejubane eliphezulu{3}}nomsebenzi osindayo, futhi ingagcina i-thrust ezinzile ngesivinini esiphezulu. Ilungele izimo ezinemithwalo ephakathi ukuya phezulu (kufika ezinkulungwaneni zamathoni amasha) kanye ne-inertia ephezulu.

5. Izindleko ezihlukene kanye nobunzima

I-Linear stepper motor actuator: isakhiwo esilula, asikho isidingo sezinzwa zempendulo, isiyingi sokulawula esenziwe lula, izindleko eziphansi (ngokuvamile u-1/3~1/2 wesistimu ye-servo), ubunzima obuphansi bokulungisa iphutha, ilungele okokusebenza-okunosayizi omncane naphakathi nesabelomali esilinganiselwe.

I-Linear servo motor actuator: idinga ukuhlanganiswa kwezinzwa kanye nama-algorithms okulawula iluphu avaliwe, okubiza kakhulu, futhi ukulungisa iphutha kwesilawuli (okufana nokushuna kwepharamitha) kuyinkimbinkimbi kakhulu, okuyenza ifaneleke okokusebenza okunembayo okunezidingo zokusebenza okuphezulu.

6. Izimo ezisebenzayo ezihlukene

I-Linear stepper motor actuator: ifanele ukunemba okuphansi, umthwalo omncane, izimo zokunyakaza eziphindaphindayo-eziphansi ngesivinini, njengokuphakelayo kwe-nozzle yephrinta ye-3D, okokusebenza okuncane kokudlulisa, ukuma kwesiteji sesampuli yaselabhorethri, isilawuli sevalvu yesisetshenziswa sasekhaya, njll.

I-Linear servo motor actuator: ifanele-ukunemba okuphezulu, ukulayisha okuphezulu,{1}}izimo zokuphendula eziguquguqukayo eziphezulu{1}}ezifana nokubamba i-semiconductor wafer, ukuma kwe-laser cutting, ukunemba kwamarobhothi, okokusebenza kwezokwelapha, njll.

Ithebula Elifingqiwe kanye Nokuqhathanisa

Lapho ukhetha, kuyadingeka ukwenza isinqumo esibanzi esisuselwe kuzimfuneko zohlelo lokusebenza zokunemba, isivinini, umthwalo, kanye nesabelomali sezindleko: kuzimo ezingasindi nezilula, ukunyathela kuyathandwa, kuyilapho{0}}izimo ezinembile neziphezulu eziguqukayo, i-servo iyadingeka.
