Linear Motion Actuator

Linear motion actuator ndi chipangizo choyendetsa chomwe chimasintha mitundu yosiyanasiyana ya mphamvu kuti ikhale yoyenda. Pachimake chake ndikusintha mwachindunji mphamvu ya gwero lamagetsi kukhala zochita zofananira monga kukankha, kukoka, kukweza, ndi zina zambiri kudzera pamakina. Mosiyana ndi njira zovuta zowongolera za nsanja yoyenda, Linear motion actuator imayang'ana kwambiri pakuphatikizika kwa mphamvu yamagetsi ndi kuthamangitsidwa, ndipo imagwiritsidwa ntchito kwambiri pazochitika zomwe zimafuna kuyendetsa mwachindunji katundu kuti ayende mozungulira.

Mfundo yake yogwirira ntchito imayenderana ndi "kutulutsa mphamvu zosinthira mphamvu". Magwero amagetsi monga ma motors a DC, mapampu a hydraulic, ndi masilinda a pneumatic amapereka mphamvu, zomwe zimasinthidwa kukhala zosunthika kudzera m'njira zopatsirana mkati monga ma screw nuts, ma gear racks, push rods, ndi zina zotero. Mtundu wa hydraulic umagwiritsa ntchito kuthamanga kwa hydraulic kukankhira pisitoni ndikutulutsa mwachindunji axial thrust. Mitundu ina yolondola imaphatikizira masensa a malo, omwe angapereke ndemanga zenizeni za nthawi-panthawi ya kusamuka ndikukwaniritsa kusintha kosinthika kwa sitiroko.

Pankhani ya kugwiritsa ntchito, muzochita zamafakitale, ma actuators amagetsi amagetsi nthawi zambiri amagwiritsidwa ntchito pokankhira zinthu pamizere yopanga, yomwe imakwaniritsa kukankhira kolondola kwa mikwingwirima ya centimita kudzera pakufalitsa wononga, m'malo mwa masilinda achikhalidwe kuti achepetse kudalira gwero la mpweya; Pazida zamankhwala, njira yokweza ya mabedi achipatala amagetsi imayendetsedwa ndi galimoto ya DC yokhala ndi screw trapezoidal, kudalira kudziletsa-zikhalidwe zotsekera kuti zitsimikizire kukhazikika kwa malo a wodwalayo pambuyo pa kusintha; M'nyumba zanzeru, chigawo chokwera cha tebulo lonyamulira chimakhala ndi cholumikizira cholumikizira chachete, chomwe chimatha kusintha-liwiro ndi utali wosalala kudzera m'makina ochepetsera zida; M'makina aulimi, ma hydraulic linear actuators amagwiritsidwa ntchito kukweza ndi kutsitsa mutu wa chotuta, womwe umagwiritsa ntchito{2}}mafuta opanikizika kwambiri kuti atulutse mphamvu zambiri komanso kusintha kusintha kwa katundu m'munda. Kuphatikiza apo, kusintha kwa bracket kwa solar tracking system, kuyendetsa kwa zipata ndikutsegula, ndi zochitika zina zimadaliranso ma linear motion actuators kuti akwaniritse mphamvu zama mzere. Kapangidwe kake kophatikizika kamapangitsa kukhala kopindulitsa kuposa nsanja zoyenda m'malo ochepa.

Apa, tikuyambitsa Linear motion actuator, TMSL135-CM ndi data motere:

Njira yodziwira zolondola ya Linear motion actuator
1.Positioning kulondola kuzindikira
Mangani njira yoyezera pogwiritsa ntchito laser interferometer, konzani chowunikira papulatifomu, ndikuyika malo ozindikira angapo motsatira axis yoyenda (monga muyeso umodzi pa 50mm iliyonse). Pambuyo pa nsanja ikupita ku malo omwe akugwiritsidwa ntchito molingana ndi malangizo, lembani kupatuka pakati pa kusamutsidwa kwenikweni komwe kumawonetsedwa ndi laser interferometer ndi mtengo wa malangizo, ndikuwerengera mtengo wapamwamba wopatuka panthawi yonse ya sitiroko, yomwe ndi malo olondola. Mwachitsanzo, mu nsanja yodziwira semiconductor yokhala ndi sitiroko ya 300mm, ngati kupatuka kwakukulu ndi ± 0.003mm, kumakwaniritsa zofunikira zakuyika kwa micrometer. Pakuyesa, tcheru chiyenera kuperekedwa ku kutentha kozungulira (kuyendetsedwa pa 20 ± 0.5 digiri) kuti mupewe kusintha kwa kutentha komwe kungayambitse kuwonjezereka kwa kutentha ndi kutsika kwa njanji yowongolera ndikukhudza deta.

2.Kubwereza kubwereza kulondola kwa malo
Sankhani malo okhazikika (kawirikawiri pakatikati) mkati mwaulendo, ndipo pulatifomu ibwerezenso njira yomweyi kuti musunthire pamalopo (nambala yovomerezeka Kuposa kapena yofanana ndi 30). Gwiritsani ntchito grating kapena mkulu{2}}yoyezera kuyimba molondola kuti mulembe malo enieni mukafika kulikonse. Werengetsani kupatuka kokhazikika kwa datayi, komwe ndi kubwereza kubwereza. Ngati kupatuka kokhazikika kwa miyeso 30 pa nsanja ina ya chida cha makina ndi 0.001mm, zikuwonetsa kukhazikika kobwerezabwereza. Asanayesedwe, nsanjayo imayenera kuthamanga popanda katundu kwa mphindi 10 kuti itenthetse ndikuchepetsa kukhudzidwa kwa kutentha kwagalimoto pakuwongolera kufalikira.

3.Kuzindikira zolakwika zowongoka
Konzani mulingo wolondola wofananira ndi axis of motion pamunsi, ikani choyezera choyezera cholumikizira pa chowongolera, ndikulumikizana pakati pa mutu wa geji ndi malo ogwirira ntchito. Pulatifomu ikamayenda pa liwiro losalekeza, kugwedezeka kwa cholozera cholozera kumawonetsa kupatuka kwa kuwongoka, komwe kumagawidwa m'njira yopingasa (kumanzere-kugwedezeka kumanja) ndi kulunjika (kusinthasintha kwa mmwamba ndi pansi). Mwachitsanzo, ngati ofukula kuwongoka cholakwa cha laser kudula nsanja kuposa 0.02mm/m'm, zingachititse amatsatira chitsanzo pa kudula pamwamba. Pakuyezetsa, ndikofunikira kuwonetsetsa kuti wolamulira wathyathyathya adayikidwa bwino kuti asasokonezedwe ndi kupotoza kwake pazotsatira.

Kuyesa kwa 4.Kukhazikika pakugwira ntchito
Ikani masensa a vibration papulatifomu ndikujambulitsa mathamangitsidwe a vibration pa liwiro losiyana (nthawi zambiri mu mm/s ²). Panthawi yothamanga kwambiri-(monga 300mm/s), ngati kugwedezeka kuchulukira mwadzidzidzi, kungayambitsidwe ndi kukanika kofanana kwa lamba kapena kuvala kwa slider. Kuphatikiza apo, maphokoso anthawi ndi nthawi amatha kuzindikirika kudzera m'malingaliro am'mutu, ndipo kutentha kwa ma motor ndi screw bearings kumatha kuyang'aniridwa ndi thermometer ya infrared. Ngati kutentha kwa gawo lina kupitirira madigiri 40, kungayambitse kuchedwa kwa ntchito chifukwa cha mafuta ochepa, omwe amakhudza kulondola.

5.Kutsimikizika kolondola pansi pamikhalidwe yolemetsa
Tsanzirani zochulukira zenizeni (monga kuyika zosintha zolemera zofananira), bwerezani zomwe zili pamwambapa ndikubwerezanso kuzindikira komwe kuli. Mapulatifomu ena amakwaniritsa miyezo yolondola akamatsitsa, koma kupindika kumachitika chifukwa cha kusakhazikika kwa njanji zowongolera pambuyo potsitsa, zomwe zimapangitsa kuti pakhale kupatuka. Mwachitsanzo, pamene gawo lomasulira la bedi lachipatala la CT likunyamula 150kg, ngati malo olondola asintha kuchoka pa ± 0.01mm pamene atsitsidwa kufika ± 0.03mm, m'pofunika kufufuza ngati ndondomeko yothandizira njanji ikufunika kulimbikitsidwa.
