I-Linear Motion Actuator

I-Linear motion actuator iyisisetshenziswa esishayelayo esiguqula izinhlobo ezahlukene zamandla zibe ukunyakaza okuqondile. Umongo wayo ukuguqula ngokuqondile amandla omthombo wamandla enze izenzo ezilandelanayo njengokusunduza, ukudonsa, ukuphakamisa, njll. ngokusebenzisa isakhiwo sokusebenza. Ngokungafani nesistimu yokuqondisa eyinkimbinkimbi yeplathifomu enyakazayo, i-Linear actuator igxile kakhulu ekuhlanganisweni kokuphuma kwamandla kanye nokwenziwa kokugudluza, futhi isetshenziswa kakhulu ezimeni ezidinga ukushayela okuqondile kwemithwalo yokunyakaza okuqondile.

Umgomo wayo wokusebenza uzungeza "ekudlulisweni kokunyakaza kokuguqulwa kwamandla". Imithombo yamandla enjengamamotho e-DC, amaphampu asebenza ngogesi, namasilinda womoya anika amandla, abese eguqulelwa ekugudluzweni ngomugqa ngokusebenzisa izindlela zokudlulisela zangaphakathi ezifana nezikulufu, ama-gear racks, ama-push rods, njll. Uhlobo lwe-hydraulic lusebenzisa i-hydraulic pressure ukusunduza i-piston kanye nokukhipha i-axial thrust ngqo. Amanye amamodeli anembayo ahlanganisa izinzwa zendawo, ezinganikeza{3}}impendulo yesikhathi sangempela ekususweni futhi kufinyelele ukulungiswa kwe-stroke okulawulwayo.

Ngokohlelo lokusebenza, kuma-automation ezimbonini, ama-actuator alayini kagesi avame ukusetshenziselwa ukusunduza okubalulekile emigqeni yokukhiqiza, efinyelela ukusunduzwa okunembile kwezinga lesentimitha ngokudluliswa kwesikulufu, esikhundleni samasilinda endabuko ukunciphisa ukuncika komthombo wegesi; Emishinini yezokwelapha, indlela yokuphakamisa imibhede yasesibhedlela esebenza ngogesi ishayelwa injini ye-DC ene-trapezoidal screw, ethembele-ezicini zokuzikhiya ukuze kuqinisekiswe ukuzinza kwendawo yesiguli ngemva kokulungiswa; Ezindlini ezihlakaniphile, ikholomu yedrayivu yetafula eliphakamisayo isebenzisa i-actuator yomugqa othulile, efinyelela ukulungiswa kobude obuphansi-bushelelezi ngokusebenzisa indlela yokunciphisa igiya; Emkhakheni wemishini yezolimo, ama-hydraulic linear actuators asetshenziselwa ukuphakamisa nokwehlisa inhlokweni yesivuni, esebenzisa{2}}uwoyela wengcindezi ephezulu ukuze ukhiphe i-thrust ephezulu futhi uvumelane nezinguquko eziyinkimbinkimbi zomthwalo ensimini. Ngaphezu kwalokho, ukulungiswa kukabakaki kwesistimu yokulandela umkhondo welanga, ukushayela kokuvuleka nokuvalwa kwesango, nezinye izimo nazo zithembele kuma-activator anyakazayo ukuze kuzuzwe amandla omugqa osebenza kahle. Ukwakheka kwayo okuhlangene kuyenza ibe nenzuzo enkulu kunezinkundla ezinyakazayo ezimweni ezinomkhawulo wesikhala.

Wamukelekile ukuthi ubukele amaphrojekthi amaningi noma uvakashele igalari yethu yevidiyo nge-Youtube: https://www.youtube.com/@tallmanrobotics

Lapha, sethula i-Linear motion actuator, i-TMSL135-CM ngedatha kanje:

Indlela yokuthola ukunemba ye-Actuator enyakazayo ye-Linear
1.Positioning ukunemba ukuthola
Yakha isistimu yokulinganisa usebenzisa i-laser interferometer, lungisa isibonisi kusilayida seplathifomu, futhi usethe izindawo eziningi zokutholwa ku-eksisi enyakazayo (njengephoyinti elilodwa lokulinganisa njalo ngo-50mm). Ngemva kokuthi isiteji sithuthela endaweni okuqondiswe kuyo ngokwemiyalo, qopha ukuchezuka phakathi kokususwa kwangempela okuboniswa i-laser interferometer kanye nenani lomyalelo, futhi ubale inani eliphakeme lokuchezuka kuyo yonke i-stroke, okuwukunemba kokuma. Isibonelo, kuplathifomu yokutholwa kwe-semiconductor ene-stroke engu-300mm, uma ukuchezuka okuphezulu kungu-± 0.003mm, kuhlangabezana nezimfuneko zokubeka izinga le-micrometer. Ngesikhathi sokuhlolwa, kufanele kuqashelwe izinga lokushisa le-ambient (elilawulwa ku-20 ± 0.5℃) ukuze kugwenywe ukushintsha kwezinga lokushisa okungase kubangele ukwanda okushisayo nokufinyela kukajantshi oqondisayo futhi kuthinte idatha.

2.Ukutholwa kokunemba kokuma okuphindaphindiwe
Khetha iphoyinti eligxilile (ngokuvamile indawo emaphakathi) phakathi nohlelo, futhi wenze inkundla iphinde inqubo efanayo ukuze iye kulelo phuzu (inombolo enconyiwe yezikhathi Ezinkulu noma ezilingana no-30). Sebenzisa irula yokugaya noma{2}}igeji yokudayela enembayo ephezulu ukuze urekhode indawo yangempela ngemva kokufika ngakunye. Bala ukuchezuka okujwayelekile kwale datha, okuwukunemba kokuphinda. Uma ukuchezuka okujwayelekile kwezilinganiso ezingu-30 endaweni ethile yethuluzi lomshini kungu-0.001mm, kubonisa ukuzinza okuhle kakhulu kokuphindaphinda. Ngaphambi kokuhlola, inkundla idinga ukusebenza ngaphandle komthwalo imizuzu eyi-10 ukuze ishise kuqala futhi yehlise umthelela wokukhuphuka kwezinga lokushisa kwemoto ekunembeni kokudlulisela.

3.Ukutholwa kwephutha lokuqina
Lungisa izinga lokunemba elihambisana ne-eksisi yokunyakaza esisekelweni, faka i-lever dial gauge kusilayida, bese uthintana phakathi kwekhanda legeji nendawo yokusebenza yeleveli. Uma inkundla ihamba ngesivinini esingaguquki, i-amplitude yokushwibeka yesikhombi sesikhombi sokudayela sibonisa ukuchezuka kokuqondisa, okuhlukaniswa kwaba isiqondiso esivundlile (ukushwibeka kwesokunxele-kwesokudla) kanye nendawo eqondile (ukushintshashintsha phezulu naphansi). Isibonelo, uma iphutha lokuma okuqondile kweplathifomu ye-laser cutting lidlula u-0.02mm/m, lingase libangele amaphethini athambekele endaweni yokusika. Ngesikhathi sokuhlolwa, kuyadingeka ukuqinisekisa ukuthi irula eliyisicaba lifakwe ngokuvikelekile ukuze kugwenywe ukuphazamiseka ekuphambukeni kwayo emiphumeleni.

4.Ukuhlolwa kokuzinza ngesikhathi sokusebenza
Faka izinzwa zokudlidliza endaweni futhi urekhode amanani okusheshisa ukudlidliza ngesivinini esihlukile (imvamisa ku-mm/s ²). Phakathi-nokusebenza kwesivinini esiphezulu (njengo-300mm/s), uma inani lokudlidliza likhuphuka ngokuzumayo, kungase kubangelwe ukungezwani okungalingani kwebhande elihambisanayo noma ukuguga kwesilayidi sikaloliwe. Ukwengeza, imisindo engavamile ngezikhathi ezithile ingatholwa ngokubona kokuzwa, futhi izinga lokushisa le-motor kanye nama-screw bearings lingahlolwa nge-thermometer ye-infrared. Uma izinga lokushisa likhuphuka engxenyeni ethile lidlula ama-degree angu-40, kungase kubangele ukunensa kokusebenza ngenxa yokungagcotshwa kahle, okuthinta ngokungaqondile ukunemba.

5.Ukuqinisekisa ukunemba ngaphansi kwezimo zomthwalo
Lingisa imithwalo yangempela yomsebenzi (njengokufaka izinto zesisindo esihambelanayo), phinda ukuma okungenhla bese uphinda ukuthola indawo. Ezinye izinkundla zihlangabezana nezindinganiso zokunemba lapho zithululwa, kodwa ukuguquguquka kwenzeka ngenxa yokungaqini okwanele kwamareyili angumhlahlandlela ngemva kokulayisha, okuholela ekuphambukeni okwandisiwe. Isibonelo, uma isigaba sokuhumusha sombhede we-CT yezokwelapha sithwala u-150kg, uma ukunemba kokuma kushintsha ukusuka ku-± 0.01mm lapho kulayishwa kuye ku-± 0.03mm, kuyadingeka ukuhlola ukuthi ingabe isakhiwo sokusekela ujantshi ongumhlahlandlela sidinga ukuqiniswa.
