Iko kugadzirwa uye shanduko yeinotemerwa IS bhodhoro kugadzira muchina
Mukutanga kwema1920s, akatangira kambani yeBuch Emhart muHartford akaberekwa wekutanga determinant bhodhoro kugadzira muchina (Individual Section), iyo yakakamurwa kuita akati wandei akazvimirira mapoka, rimwe nerimwe boka Rinogona kumira uye kushandura mold yakazvimirira, uye mashandiro uye management iri nyore kwazvo.Iwo mana-chikamu IS mutsara-mhando yekugadzira bhodhoro muchina.Chikumbiro chemvumo chakaiswa pana Nyamavhuvhu 30, 1924, uye hachina kugamuchirwa kutozosvikira February 2, 1932. .Mushure mekunge modhi yaenda pakutengesa kwekutengesa muna 1927, yakawana mukurumbira wakapararira.
Kubva pakugadzirwa kwechitima chinozvifambisa, chapfuura nematanho matatu ekusvetuka kwetekinoroji: (3 Technology Periods kusvika zvino)
1 Kugadziridzwa kwemuchina IS rank muchina
Munhoroondo refu kubva muna 1925 kusvika 1985, muchina wekugadzira mabhodhoro wemutsetse wemutsara ndiwo waive muchina mukuru muindasitiri yekugadzira mabhodhoro.Idhiramu remuchina/pneumatic cylinder drive (Timing Drum/Pneumatic Motion).
Kana iyo mechanical drum inofananidzwa, sezvo dhiramu rinotenderera bhatani revharuvhu padhiramu rinotyaira kuvhura nekuvhara kwevharuvhu muMechanical Valve Block, uye mweya wakamanikidzwa unotyaira silinda (Silinda) kuti idzorere.Ita chiito chakakwana maererano nekugadzirisa maitiro.
2 1980-2016 Iripo (nhasi), yemagetsi nguva yechitima AIS (Advantage Individual Section), yemagetsi nguva yekudzora / pneumatic cylinder drive (Electric Control / Pneumatic Motion) yakagadzirwa uye nekukurumidza kuiswa mukugadzirwa.
Inoshandisa microelectronic tekinoroji kudzora maitiro ekugadzira akadai sekugadzira mabhodhoro uye nguva.Kutanga, chiratidzo chemagetsi chinodzora solenoid valve (Solenoid) kuti iwane chiito chemagetsi, uye zvishoma zvishoma zvemhepo yakamanikidzwa inopfuura nekuvhura uye kuvhara kwevhavha ye solenoid, uye inoshandisa gesi iyi kudzora sleeve valve (Cartridge).Uye wozodzora kufamba kweteresikopu kwecylinder yekutyaira.Ndiko kuti, inonzi magetsi inodzora mhepo ine stingy, uye mhepo inoonja inodzora mhepo.Seruzivo rwemagetsi, chiratidzo chemagetsi chinogona kukopwa, kuchengetwa, kuvharirwa uye kuchinjana.Naizvozvo, kutaridzika kwemagetsi ekugadzirisa nguva muchina AIS akaunza nhevedzano yehunyanzvi kumuchina wekugadzira mabhodhoro.
Parizvino, mazhinji mabhodhoro egirazi uye anogona mafekitori kumba nekune dzimwe nyika anoshandisa iyi mhando yemuchina wekugadzira mabhodhoro.
3 2010-2016, full-servo row machine NIS, (New Standard, Electric Control / Servo Motion).Servo motors dzakashandiswa mumichina yekugadzira mabhodhoro kubvira munenge muna 2000. Dzakatanga kushandiswa mukuvhura uye kusungirirwa kwemabhodhoro pamushini wekugadzira mabhodhoro.Nheyo ndeyekuti iyo microelectronic chiratidzo inokwidziridzwa nedunhu kudzora zvakananga uye kutyaira chiito che servo mota.
Sezvo servo mota isina pneumatic drive, ine zvakanakira kuderera kwesimba rekushandisa, hapana ruzha uye nyore kutonga.Ikozvino yakagadzira kuita yakazara servo bhodhoro kugadzira muchina.Nekudaro, tichifunga nezvekuti hakuna mafekitori mazhinji anoshandisa yakazara-servo kugadzira mabhodhoro muChina, ini ndichasuma zvinotevera maererano neruzivo rwangu rusina kudzika:
Nhoroondo uye Kubudirira kweServo Motors
Pakazosvika pakati-kusvika-kupera kwema1980, makambani makuru munyika aive nemhando yakakwana yezvigadzirwa.Naizvozvo, iyo servo mota yakasimudzirwa nesimba, uye kune akawanda akawandisa ekushandisa minda ye servo mota.Chero bedzi paine sosi yemagetsi, uye paine chinodiwa chechokwadi, inogona kazhinji kusanganisira servo mota.Zvakadai sezvishandiso zvakasiyana-siyana zvekugadzira muchina, michina yekudhinda, yekurongedza, machira emidziyo, laser yekugadzirisa michina, marobhoti, akasiyana otomatiki mitsara yekugadzira uye zvichingodaro.Zvishandiso zvinoda kurongeka kwemaitiro epamusoro, mashandiro ekugadzirisa uye kuvimbika kwebasa zvinogona kushandiswa.Mumakumi maviri emakore apfuura, makambani ekugadzira mabhodhoro ekunze ekugadzira muchina akatorawo servo motors pamichina yekugadzira mabhodhoro, uye akashandiswa zvinobudirira mumutsara chaiwo wekugadzira wemabhodhoro egirazi.muenzaniso.
Kuumbwa kwe servo motor
Mutyairi
Chinangwa chekushanda che servo drive chinonyanya kuenderana nemirairo (P, V, T) yakabudiswa nemukuru wepamusoro.
Servo mota inofanirwa kuve nemutyairi wekutenderera.Kazhinji, isu tinodaidza servo mota kusanganisira mutyairi wayo.Iyo ine servo mota inofananidzwa nemutyairi.Iyo general AC servo mota yekutyaira mutyairi nzira inowanzo patsanurwa kuita matatu ekudzora modhi: chinzvimbo servo (P command), kumhanya servo (V command), uye torque servo (T command).Iyo yakawanda yakajairika nzira dzekudzora inzvimbo servo uye kumhanya servo.Servo Motor
Iyo stator uye rotor ye servo mota inoumbwa nemagineti echigarire kana iron core coils.Iwo magineti echigarire anogadzira magineti uye masimbi epakati coils anozogadzirawo magineti mushure mekupihwa simba.Kudyidzana pakati pe stator magnetic field uye rotor magnetic field inogadzira torque uye inotenderera kutyaira mutoro, kuitira kuendesa simba remagetsi muchimiro chemagnetic field.Yakashandurwa kuita simba remagetsi, iyo servo mota inotenderera kana paine chiratidzo chekutonga, uye inomira kana pasina chiratidzo chekuisa.Nekushandura chiratidzo chekudzora uye chikamu (kana polarity), kumhanya uye kutungamira kweiyo servo mota inogona kuchinjwa.Iyo rotor mukati me servo mota igineti yekusingaperi.Iyo U / V / W matatu-chikamu magetsi anodzorwa nemutyairi anoumba iyo electromagnetic field, uye rotor inotenderera pasi pechiito cheiyi magnetic field.Panguva imwe chete, mhinduro yechiratidzo che encoder inouya nemotokari inotumirwa mutyairi, uye mutyairi anofananidza kukosha kwemhinduro nechinangwa chekugadzirisa kugadzirisa kona yekutenderera ye rotor.Iko kurongeka kweiyo servo mota inotarwa nekurongeka kweiyo encoder (nhamba yemitsara)
Encoder
Nechinangwa che servo, encoder inoiswa coaxially painobuda mota.Iyo mota uye encoder inotenderedza synchronously, uye encoder zvakare inotenderera kana mota ichitenderera.Panguva imwe chete yekutenderera, chiratidzo che encoder chinodzoserwa kumutyairi, uye mutyairi anotonga kana kutungamira, kumhanya, chinzvimbo, nezvimwe zve servo mota ndizvo chaizvo zvinoenderana neiyo encoder siginecha, uye anogadzirisa kubuda kwemutyairi. zvinoenderana.Iyo encoder inosanganiswa ne servo mota, yakaiswa mukati me servo mota
Iyo servo system ndeye otomatiki yekudzora sisitimu inogonesa kubuda kudzora huwandu hwakadai sechinzvimbo, kutarisisa, uye mamiriro echinhu kutevedzera shanduko dzechimbichimbi dzechinangwa chekuisa (kana kukosha kwakapihwa).Kuteedzera kwayo servo kunonyanya kutsamira pamapulses ekumisikidza, ayo anogona kunyatso kunzwisiswa sezvizvi: iyo servo mota inotenderedza kona inoenderana ne pulse painogashira kupuruzira, nekudaro ichiziva kusimuka, nekuti encoder mu servo mota inotenderera, uye. inokwanisa kutumira Basa rekupuruzira, saka pese pese iyo servo mota ichitenderera kona, inotumira iyo inowirirana nhamba yemapulses, iyo inonongedza pulses inogamuchirwa ne servo mota, uye kuchinjanisa ruzivo uye data, kana a rakavharwa loop.Mangani mapurusi anotumirwa kune servo mota, uye mangani mapurusi anogamuchirwa panguva imwe chete, kuitira kuti kutenderera kwemota kugone kudzorwa nemazvo, kuitira kuti uwane chaiyo chinzvimbo.Mushure mezvo, inotenderera kwechinguva nekuda kwe inertia yayo, uye yobva yamira.Iyo servo mota ndeyekumira kana yamira, uye kuenda kana ichinzi iende, uye mhinduro inokurumidza zvakanyanya, uye hapana kurasikirwa kwenhanho.Kururama kwayo kunogona kusvika 0.001 mm.Panguva imwecheteyo, iyo nguva yekupindura yekumhanyisa uye kudzika kweiyo servo mota zvakare ipfupi kwazvo, kazhinji mukati memakumi emamilliseconds (1 sekondi yakaenzana ne1000 milliseconds)Pane yakavharwa loop yeruzivo pakati pe servo controller nemutyairi weservo pakati. chiratidzo chekudzora uye mhinduro yedata, uye kune zvakare chiratidzo chekudzora uye mhinduro yedata (yakatumirwa kubva kune encoder) pakati pemutyairi weservo uye servo mota, uye ruzivo rwuri pakati pavo runoumba chivharo chakavharwa.Naizvozvo, kutonga kwayo kuwiriranisa kurongeka kwakakwira zvakanyanya
