Amasistimu okunyakaza alayini - ahlanganisa isisekelo noma izindlu, isistimu yomhlahlandlela, nendlela yokushayela - ayatholakala ngemiklamo ehlukahlukene kanye nokucushwa ukuze afanele cishe noma yiluphi uhlelo lokusebenza.Futhi ngenxa yokuthi imiklamo yabo ihlukahluka kakhulu, ivame ukuhlukaniswa ngokuya ngezimiso ezibalulekile zokwakha kanye nezimiso zokusebenza.Iphuzu elikhona: Igama elithi “i-actuator” ngokuvamile libhekisela kusistimu yokunyakaza ewumugqa enendlu ye-aluminium efaka umhlahlandlela kanye nezindlela zokushayela;amasistimu abizwa ngokuthi “amathebula,” noma “amathebula e-XY,” ngokuvamile aklanywa nge-baseplate eyisicaba lapho umhlahlandlela nezingxenye zedrayivu zigxunyekwe khona;kanye “nesiteji somugqa” noma “isigaba sokuhumusha esiwumugqa” ngokuvamile sisho isistimu efanayo ekwakhiweni kwetafula lomugqa kodwa eklanyelwe ukunciphisa amaphutha ekumiseni nasekuhambeni.
Amasistimu okunyakaza ngomugqa angabonisa izinhlobo ezintathu zamaphutha: amaphutha emigqa, amaphutha angular, namaphutha epulani.
Amaphutha omugqa amaphutha ekumiseni ukunemba nokuphindaphinda, athinta ikhono lesistimu lokufinyelela endaweni oyifunayo.
Amaphutha e-angular - ngokuvamile abizwa ngokuthi i-roll, pitch, ne-yaw - ahlanganisa ukuzungezisa mayelana nezimbazo ezingu-X, Y, kanye no-Z, ngokulandelanayo.Amaphutha e-angular angaholela kumaphutha e-Abbé, okungamaphutha e-angular akhuliswe ibanga, njengebanga phakathi komhlahlandlela womugqa (umthombo wephutha le-angular) kanye nephuzu lethuluzi ledivayisi yokulinganisa.Kubalulekile ukuqaphela ukuthi amaphutha angama-angular akhona ngisho noma isiteji singanyakazi, ngakho angaba nomthelela omubi ekusebenzeni okumile njengokulinganisa noma ukugxila.
Amaphutha e-Planar avela ezinhlotsheni ezimbili - ukuchezuka ekuhambeni endizeni evundlile, okubhekiselwa kukho njengokuqondile, kanye nokuchezuka ekuhambeni endizeni eqondile, okubhekiselwa kukho njengokucaba.
Nakuba ingekho imithetho noma iziqondiso eziqinile zalokho okuhlanganisa isiteji somugqa, zaziwa kabanzi njengesigaba esinembe kakhulu sesistimu yokunyakaza eqondile.Uma isistimu ibizwa ngokuthi yisiteji somugqa, ngokuvamile kuyaqondakala ukuthi isistimu izohlinzeka hhayi nje ngokunemba kokuma okuphezulu nokuphindaphinda, kodwa futhi namaphutha aphansi e-angular kanye ne-planar.Ukuze kuzuzwe leli zinga lokusebenza, kunezimiso eziningana abakhiqizi abavame ukuzilandela mayelana nokwakhiwa kanye nohlobo lwezingxenye ezisetshenziswa ekwakhiweni kwesiteji.
Lesi sigaba somugqa sisebenzisa ama-bearings wesitimela anephrofayili ane-linear motor drive.
Okokuqala, ngokungafani nezinye izinhlelo ezinyakazayo ezinomugqa, ezivame ukusebenzisa i-aluminium extrusion noma ipuleti njengesisekelo, isiteji esiwumugqa siqala ngesisekelo esinembayo.Izigaba ezidizayinelwe amazinga aphezulu okucaba, ukuqondisa, nokuqina ngokuvamile zisebenzisa isisekelo esenziwe ngensimbi noma ngegranite, nakuba i-aluminium isetshenziswa kweminye imiklamo.Insimbi negwadle nakho kunama-coefficients aphansi okwandisa okushisayo kune-aluminium, ngakho abonisa ukuzinza okungcono kobukhulu ezindaweni ezinamazinga okushisa aphakeme noma ahlukahlukene.
Uhlelo lomhlahlandlela womugqa luphinde lube nomthelela ekuqondeni nasekuphepheni kohambo, ngakho izindlela zomhlahlandlela ezikhethwayo zesiteji esiwumugqa zingamareyili anephrofayili anembayo,amaslayidi e-roller ephambanisiwe, nomaama-air bears.Lezi zinhlelo zomhlahlandlela ziphinde zinikeze ukwesekwa okuqinile ukuze kuncishiswe amaphutha angama-angular, okungaholela emaphutheni e-Abbé uma kukhona ukulungisa phakathi komsuka wephutha (umhlahlandlela) kanye nephuzu lenzuzo (iphuzu lamathuluzi noma indawo yokulayisha).
Nakuba izinhlobo eziningi zamasistimu okunyakaza omugqa zisebenzisa izindlela zokushayela ezinembe kakhulu, izigaba eziwumugqa zisebenzisa kakhulu ubuchwepheshe obubodwa kobubili: isikulufu sebhola esinembe kakhulu noma injini yomugqa.Amamotho alayini ngokuvamile ahlinzeka ngezinga eliphezulu kakhulu lokunemba kokuma nokuphindaphindeka, njengoba eqeda ukuthobela kanye nokuhlehla okukhona ku-drivetrain ewumshini kanye nokuhlangana phakathi kwedrayivu nenjini.Odabeni olukhethekile lwemisebenzi yokubeka i-sub-micron,ama-actuator we-piezonomaizinjini zekhoyili yezwingokuvamile ziyizindlela zokushayela ezikhethwayo, ngokunyakaza kwazo okunembe kakhulu, okuphindaphindwayo.
Nakuba igama elithi “isiteji somugqa” lisho uhlelo lokunyakaza lwe-eksisi eyodwa, izigaba zingahlanganiswa ukuze zakhe amasistimu e-multi-eksisi njengezigaba ze-XY,izigaba ezihleliwe, kanye nezigaba ze-gantry.
Lesi sigaba se-gantry esinama-axis amabili sisebenzisa ama-air bearings nama-linear motors kusisekelo se-ceramic.
