Ungaqinisekisa Kanjani Ukunemba Kwamarobhothi E-Servo Angama-Axis Amahlanu? Kusukela Kubuchwepheshe Obuyinhloko Kuya Ekusetshenzisweni

Ekukhiqizeni ngokunemba, ekuhlanganisweni kwe-elekthronikhi, ekucutshungulweni kwamadivayisi ezokwelapha, nakwezinye izinkambu, ukunemba kwamarobhothi e-servo ane-axis emihlanu kunquma ngqo ikhwalithi yomkhiqizo kanye nokusebenza kahle kokukhiqiza. Uma kuqhathaniswa ne-three-Amarobhothi e-Axis,izinhlelo ezinama-axis amahlanu, ngama-axes amabili engeziwe ajikelezayo (ngokuvamile ama-axes e-A, C, noma e-B), angafeza ukunyakaza kwendawo okuyinkimbinkimbi kakhulu, kodwa lokhu futhi kubeka izidingo eziphakeme ekulawuleni ngokunemba—ngisho nephutha elingu-0.01mm lingabangela ukumiswa kwezingxenye ze-scrap kanye nemigqa yokukhiqiza. Lesi sihloko sizohlaziya izindlela ezibalulekile zokuqinisekisa ukunemba kwamarobhothi e-servo ane-axis emihlanu kusukela ezicini ezinhlanu eziyinhloko: ukwakheka kwemishini, uhlelo lwe-servo, i-algorithm yokulawula, ukufakwa kanye nokuqaliswa, kanye nokugcinwa okuvamile, okuhlinzeka ngomhlahlandlela osebenzayo wokukhetha nokusebenza kwebhizinisi.

Okokuqala. Isakhiwo Semishini: "Isisekelo Esibonakalayo" Sokunemba: Ukulawulwa Kwamaphutha Okuvela Kumthombo Wokuklama

Ukunemba kwerobhothi le-servo elinezingqimba ezinhlanu kuncike kakhulu ekuzinzeni kwesakhiwo salo somshini. Noma yikuphi ukuguqulwa, ukudlala, noma ukuguguleka kwezingxenye zalo kuzohumusha ngokuqondile kube amaphutha okunyakaza. Gxila ezingxenyeni ezintathu eziyinhloko ezilandelayo:

1. Izingxenye Zokudlulisa Eziyinhloko: Ukukhetha Uhlobo Olufanele Nokunemba Kokulawula
Uhlelo lokudlulisa luyisihluthulelo kokubili ekudlulisweni kwamandla kanye nasekusetshenzisweni ngokunemba. Izindlela ezivamile zokudlulisa zifaka phakathi izikulufo zebhola, izinciphisi ze-harmonic, kanye nezinciphisi zeplanethi. Lokhu kumele kuhambisane ngokususelwa ezidingweni zomthwalo kanye nokunemba:

Izikulufu zebhola: Lezi zibangela ukuhamba kwezinsika eziqondile (njengezinsika ze-X/Y/Z). Ukunemba kwazo kuthinta ngqo iphutha lokubeka. Sincoma ukukhetha ukunemba kwe-C3 noma ngaphezulu (iphutha lokubeka ≤ 0.008mm/300mm). Indlela yokulayisha kusengaphambili (njengokulayisha kusengaphambili kwe-double-nut) kufanele isetshenziswe ukuqeda ukuhlangana phakathi kwesikulufu ne-nut. Insimbi ye-alloy enamandla aphezulu (njenge-SUJ2) kufanele ikhethwe, futhi iqiniswe (ubulukhuni bomphezulu ≥ HRC58) ukuze kuncishiswe ukuguguleka nokuguquka ngemva kokusetshenziswa isikhathi eside.

Ama-Harmonic reducers: Asetshenziselwa ama-axes ajikelezayo (njenge-A/C axes), anikeza izinzuzo ezifana nesilinganiso sokudlulisa esiphezulu kanye nosayizi ohlangene. Kodwa-ke, ukuguqulwa kwe-elastic kwe-flexspline kungabangela amaphutha okubuyisa. Khetha imodeli enembile kakhulu enephutha lokubuyisa elingu-≤1 arc minute. Futhi, lawula isivinini sokufaka (gwema ukudlula u-80% wejubane elilinganisiwe) ukuze unciphise umonakalo wokukhathala ku-flexspline. Eminye imishini ephezulu isebenzisa inhlanganisela ye-harmonic reducer kanye ne-absolute encoder ukuze ikhokhele amaphutha okuguqulwa kwe-elastic ngesikhathi sangempela.

Iziqondiso: Lezi ziqondisa ukunyakaza kwerobhothi futhi kumele zigcine ukufana nezingxenye zokudlulisa. Kunconywa iziqondiso ze-linear roller (zinikeza umthamo omkhulu womthwalo kanye nokuqina kuneziqondiso zebhola). Ngesikhathi sokufakwa, linganisa ukufana kwe-guide rail parallelism usebenzisa i-laser interferometer (kube yiphutha elingu-≤0.005mm/m) ukuze ugweme "ukuklebhuka" noma ukungalungi okubangelwa ukuthambekela kwe-guide rail.

2. Uhlaka: Ibhalansi phakathi kokuqina nokukhanya

Ukuqina kohlaka okunganele kungaholela "ekuguqulweni kokudlidliza" ngesikhathi sokunyakaza, ikakhulukazi ngesivinini esiphezulu noma ngaphansi kwemithwalo esindayo, lapho amaphutha akhuliswa khona. Izinto okufanele uzicabangele ngokuklama:

Ukukhethwa kwezinto: Ama-alloy e-aluminium anamandla aphezulu (njenge-6061-T6) angasetshenziswa kuma-manipulators amancane naphakathi, ukulinganisela ukukhululeka nokuqina. Ngezicelo zemithwalo esindayo (imithwalo > 50kg), insimbi ephothiwe (njenge-HT300) noma izakhiwo zensimbi ezihlanganisiwe ziyanconywa. Ukwelashwa kokuguga kungasetshenziswa ukususa ukucindezeleka kwangaphakathi nokunciphisa ukuguquka ngemva kokusetshenziswa isikhathi eside.

Ukulungiswa kwesakhiwo: Sebenzisa ukwakheka "kokusekela okungunxantathu" noma "kohlobo lwebhokisi" ukuze uthuthukise ukuqina kohlaka lokugoba. Faka izimbambo zokuqinisa ezindaweni ezithwala umthwalo oyinhloko (njengokuxhumeka kwe-axis ejikelezayo) ukuze ugweme ukugxilisa ukucindezeleka kwendawo. Isibonelo, i-manipulator yama-axis amahlanu evela kumkhiqizi wezingxenye zezimoto inciphise iphutha lokunyakaza okuguquguqukayo ngo-40% ngokwandisa ukuqina kohlaka lokugoba kusuka ku-150 N·m/° kuya ku-280 N·m/°.

3. Isiphetho: Zivumelanise nomthwalo bese unciphisa "ukwehla kokuphela"

Isisindo kanye nokunemba kokukhweza kwesitho sokuphela (njengesigibe noma indebe yokumunca) kuzothinta "ukunemba kokubekwa kokuphela" kwe-manipulator. Isimiso "sokufanisa umthwalo" kumele silandelwe:

Umthwalo wokugcina akumele udlule u-80% womthwalo olinganisiwe werobhothi (ukugwema ukuguquguquka komgodi okubangelwa ukugcwala ngokweqile);

Ukuxhumana phakathi kwe-actuator ne-robot flange kumele kuqinisekiswe kusetshenziswa izikhonkwane ze-dowel kanye nama-bolt anamandla aphezulu. Iphutha lokuthamba kobuso be-flange kumele libe ngu-≤ 0.003mm, kanti iphutha le-coaxiality kumele libe ngu-≤ 0.005mm ukuvimbela ukungalungi kokuphela ngenxa yokungalungi kokuxhumeka.

Okwesibili. Uhlelo lwe-Servo: "I-Power Core" Yokunemba, Enciphisa Ukuphambuka Ezingeni Lokulawula

Ukunemba kokunyakaza kwerobhothi le-servo elinezingqimba ezinhlanu ngokuyisisekelo "yikhono lesistimu ye-servo lokulandela imiyalo"—ngemva kokuthunyelwa komyalo, injini ye-servo, umshayeli, kanye ne-encoder kumele basebenzisane ukuze kuncishiswe amaphutha. Izici ezintathu ezilandelayo zidinga ukulungiswa okubalulekile:

1. I-Servo Motor: Khetha Uhlobo Olufanele + Thuthukisa Isixazululo

Injini ye-servo "ingumthombo wokukhipha amandla," futhi ukunemba kwayo kunquma ngqo ukushelela kokunyakaza kanye nokunemba kokubeka.

Ukukhetha Uhlobo: Ama-servo motor ahlala njalo ahambisana nemagnethi ahlala njalo ayathandwa (anikeza isivinini sokuphendula esisheshayo esingu-30% kanye ne-torque ripple engaphansi ngo-20% kunezinjini ezihambisana ne-asynchronous). Lokhu kubaluleke kakhulu ezimweni ze-start-stop ezinesivinini esikhulu (njengokuthathwa kwezingxenye ze-elekthronikhi), njengoba anganciphisa amaphutha "ezinyathelo ezilahlekile" abangelwa yi-torque enganele.

Isixazululo Sokuqopha: I-encoder "iyisici sempendulo yesikhundla." Uma isinqumo siphezulu, kulapho ukutholwa kwesikhundla kunembe khona. Kunconywa ukusebenzisa i-23-bit absolute encoder (ukunemba kokubeka ≤ 0.001mm) yama-axes aqondile kanye ne-17-bit absolute encoder (ukunemba kwe-angular ≤ 0.005°) yama-axes ajikelezayo. Uma kuqhathaniswa nama-encoder akhuphukayo, ama-absolute encoder awadingi "ukulinganiswa kwasekhaya," okungavimbela ukuphambuka kwesikhundla ngemva kokwehluleka kwamandla nokuqala kabusha.

2. Umshayeli: Lungiselela i-algorithm yokulawula ukuze unciphise iphutha elilandelayo

Umshayeli we-servo "uyisikhungo sokulawula i-motor," futhi ikhwalithi ye-algorithm yayo ithinta ngqo amakhono ayo okulungisa amaphutha. Imisebenzi elandelayo eyinhloko kumele inikwe amandla:
Ukulungisa ngokuzenzakalelayo kwepharamitha ye-PID: Umshayeli ubona ngokuzenzakalelayo umthwalo wemoto kanye ne-inertia, elungiselela amapharamitha alinganayo (P), ahlanganisiwe (I), kanye nomehluko (D) ukuze anciphise ukushaqeka ngokweqile (isb., ukushukuma ngesikhathi sokubeka). Isibonelo, ikhasimende embonini ye-3C linciphise iphutha lokulandela i-X-axis kusuka ku-0.02mm kuya ku-0.008mm ngokulungisa ngokuzenzakalelayo umshayeli.
Ukulawula Okuphakelayo: Lokhu kubikezela izinguquko zomthwalo wemoto (isb., amandla angasebenzi ngesikhathi sokusheshisa) kusengaphambili futhi kukhiphe isinxephezelo se-torque ngendlela ephumelelayo ukuze kugwenywe ukuphambuka kwesivinini okubangelwa ukushintshashintsha komthwalo. Ezimweni zokuxhumanisa ze-five-axis (isb., ukwenziwa komshini wokwenza izinto ebusweni), ukulawula okuphakelayo kunganciphisa iphutha le-contour ngaphezu kuka-30%.
Ukucindezela i-Resonance: Ukulungisa i-mechanical resonance ngesikhathi Irobhothi Mnge-ovement (isb., ukudlidliza kohlaka ngesikhathi sokunyakaza kwesivinini esikhulu), umshayeli usebenzisa "ukuhlunga ama-notch" ukuze aqede ukudlidliza kumaza athile, okunciphisa ukunemba okubangelwa ukuzwakala kwe-resonance.

3. Ukulawulwa Okuhlanganisiwe Kwe-Five-Axis: Ukuxazulula "Iphutha Lokuxhumanisa I-Inter-Axis"

Inselele enkulu ngama-manipulator angama-axis amahlanu ukuhlanganiswa kokunyakaza kwama-axis amaningi. Uma wonke ama-axis amahlanu ehamba ngasikhathi sinye, isivinini kanye nokusheshisa kwe-axis ngayinye kumele kuhambisane ngokuqinile, ngaphandle kwalokho kuzokwenzeka "amaphutha e-contour" (njengokuphambuka kwesimo lapho kucutshungulwa izindawo ezigobile). Lokhu kudinga ukulungiswa ngokusebenzisa ubuchwepheshe obulandelayo:

Ama-algorithms e-Kinematic phambili nangemuva: Sebenzisa imodeli ye-kinematic ene-axis ezinhlanu enembile kakhulu ukuze ubale ngokunembile amapharamitha okunyakaza kwe-axis ngayinye (njengokunxephezela i-engeli yama-axes ajikelezayo) ukuze ugweme amaphutha abangelwa ukusondela kwe-algorithmic. Isibonelo, ekucushweni kwe-five-axis "yesitayela se-cradle" (ama-axes e-A + C), i-algorithm kumele ikhokhele i-offset phakathi kwezikhungo zama-axes ajikelezayo naqondile.

Ukuthuthukiswa kwe-algorithm yokuhlanganisa: Sebenzisa "ukuhlanganiswa kwe-spline" noma "ukuhlanganiswa kwe-NURBS" (kunokuba kuhlanganiswe ngendlela evamile) ukuze kufezwe ukunyakaza okubushelelezi kwe-axis ngayinye futhi kuncishiswe amaphutha omthelela abangelwa izinguquko zesivinini ezisheshayo. Umkhiqizi wedivayisi yezokwelapha uthuthukise ukunemba komshini wokufakelwa wobuso obuhlangene kusuka ku-±0.03mm kuya ku-±0.015mm ngokusebenzisa ukuhlanganiswa kwe-NURBS.
