Ukuveliswa kunye nokuvela komatshini wokwenza iibhotile u-IS
Ekuqaleni kwee-1920, umanduleli wenkampani yaseBuch Emhart eHartford wazalwa umatshini wokuqala wokwenza ibhotile (iCandelo lomntu ngamnye), owahlulahlulwe ngamaqela azimeleyo amaninzi, iqela ngalinye Linokuyeka kwaye litshintshe ukubumba ngokuzimeleyo, kunye nokusebenza kunye nokuzimela. ulawulo lulula kakhulu. Ngumatshini wokwenza ibhotile onamacala amane we-IS. Isicelo selungelo elilodwa lomenzi wechiza safakwa ngoAgasti 30, 1924, yaye asizange samkelwe de kwangoFebruwari 2, 1932. Emva kokuba imodeli iqhubekile kwintengiso yorhwebo ngo-1927, yafumana ukuthandwa ngokubanzi.
Ukusukela ekuyilweni kololiwe oziqhubayo, udlule kwizigaba ezithathu zokutsiba kobuchwepheshe: (Amaxesha ama-3 eTekhnoloji ukuza kuthi ga ngoku)
1 Uphuhliso lomatshini wenqanaba le-IS lomatshini
Kwimbali ende ukusuka kwi-1925 ukuya kwi-1985, umatshini wokwenza ibhotile umatshini wawungowona matshini uphambili kwishishini lokwenza iibhotile. Ingumgqomo womatshini/i-pneumatic cylinder drive (i-Timing Drum/Pneumatic Motion).
Xa igubu lomatshini lihambelana, njengoko igubu lijikeleza iqhosha levalve kwigubu liqhuba ukuvulwa nokuvalwa kwevalve kwiMechanical Valve Block, kwaye umoya ocinezelweyo uqhube isilinda (Cylinder) ukuba ibuyele. Yenza isenzo siphelele ngokwenkqubo yokuqulunqa.
I-2 1980-2016 Ekhoyo (namhlanje), i-electronic time train train AIS (i-Advantage Individual Section), ulawulo lwexesha lombane / i-pneumatic cylinder drive (Ulawulo loMbane / i-Pneumatic Motion) yaqanjwa kwaye yafakwa ngokukhawuleza kwimveliso.
Isebenzisa itekhnoloji ye-microelectronic ukulawula izenzo zokubumba ezifana nokwenza ibhotile kunye nexesha. Okokuqala, isignali yombane ilawula i-valve ye-solenoid (i-Solenoid) ukufumana isenzo sombane, kwaye ixabiso elincinci lomoya ocinezelweyo lidlula ngokuvula kunye nokuvalwa kwe-valve ye-solenoid, kwaye isebenzisa le gesi ukulawula i-valve ye-sleeve (Cartridge). Uze ulawule intshukumo yetelescopic yesilinda sokuqhuba. Oko kukuthi, into ebizwa ngokuba ngumbane ilawula umoya ongcolileyo, kwaye umoya ohlabayo ulawula umoya. Njengolwazi lombane, umqondiso wombane unokukopishwa, ugcinwe, uvalelwe kwaye utshintshwe. Ke ngoko, ukubonakala komatshini wokulinganisa ixesha we-elektroniki i-AIS izise uthotho lwezinto ezintsha kumatshini wokwenza ibhotile.
Okwangoku, uninzi lwebhotile yeglasi kunye neefektri ezisekhaya nakwamanye amazwe zisebenzisa olu hlobo lomatshini wokwenza ibhotile.
I-3 2010-2016, umatshini womgca we-servo ogcweleyo we-NIS, (uMgangatho oMtsha, uLawulo loMbane / i-Servo Motion). Iinjini ze-Servo zisetyenziswe koomatshini bokwenza iibhotile ukususela malunga no-2000. Zaqala ukusetyenziswa ekuvuleni nasekubambeni iibhotile kumatshini wokwenza iibhotile. Umgaqo-siseko kukuba umqondiso we-microelectronic ukhuliswe yisekethe ukulawula ngokuthe ngqo kunye nokuqhuba isenzo se-servo motor.
Ekubeni i-servo motor ayinayo i-pneumatic drive, ineenzuzo zokusebenzisa amandla aphantsi, akukho ngxolo kunye nokulawula okulula. Ngoku iphuhliswe yaba ngumatshini opheleleyo wokwenza ibhotile ye-servo. Nangona kunjalo, ngenxa yenyani yokuba akukho zifektri zininzi ezisebenzisa oomatshini bokwenza iibhotile ezigcweleyo eTshayina, ndizakwazisa oku kulandelayo ngokolwazi lwam olungekho nzulu:
Imbali kunye noPhuhliso lweServo Motors
Phakathi ukuya ekupheleni kweminyaka yee-1980, iinkampani ezinkulu ehlabathini zazinoluhlu olupheleleyo lweemveliso. Ke ngoko, i-servo motor iye yakhuthazwa ngamandla, kwaye maninzi kakhulu amasimi osetyenziso lwe-servo motor. Ngethuba nje kukho umthombo wamandla, kwaye kukho imfuneko yokuchaneka, inokubandakanya ngokubanzi i-servo motor. Njengezixhobo ezahlukeneyo zoomatshini bokucwangcisa, izixhobo zokuprinta, izixhobo zokupakisha, izixhobo ezilukiweyo, izixhobo zokulungisa i-laser, iirobhothi, imigca yokuvelisa ezenzekelayo njalo njalo. Izixhobo ezifuna ukuchaneka kwenkqubo ephezulu, ukusebenza kakuhle kunye nokuthembeka komsebenzi kungasetyenziswa. Kwiminyaka engamashumi amabini edlulileyo, iinkampani zokuvelisa iibhotile zangaphandle ziye zamkela ii-servo motors koomatshini bokwenza iibhotile, kwaye zisetyenziswe ngempumelelo kumgca wemveliso weglasi. umzekelo.
Ukuqulunqwa kwe-servo motor
Umqhubi
Injongo yokusebenza ye-servo drive isekelwe ikakhulu kwimiyalelo (P, V, T) ekhutshwe ngumlawuli ophezulu.
I-servo motor kufuneka ibe nomqhubi wokujikeleza. Ngokubanzi, sibiza i-servo motor kubandakanya nomqhubi wayo. Iqukethe i-servo motor ehambelana nomqhubi. Indlela yokulawula umqhubi we-AC servo jikelele ngokubanzi yahlulahlulwe kwiindlela ezintathu zokulawula: i-servo yendawo (umyalelo we-P), i-speed servo (umyalelo we-V), kunye ne-torque servo (umyalelo we-T). Iindlela zolawulo ezixhaphake ngakumbi zisikhundla se-servo kunye nesantya se-servo.Servo Motor
I-stator kunye ne-rotor ye-servo motor yenziwe ngamagnethi asisigxina okanye iikhoyili zentsimbi. Iimagnethi ezisisigxina zivelisa umhlaba wemagnethi kwaye iikhoyili ezingundoqo zentsimbi nazo ziya kuvelisa imagnethi emva kokuba zinikwe amandla. Intsebenziswano phakathi kwe-stator magnetic field kunye ne-rotor magnetic field ivelisa i-torque kwaye ijikeleze ukuqhuba umthwalo, ukwenzela ukuba kudluliselwe amandla ombane ngendlela ye-magnetic field. Ukuguqulwa kumandla omatshini, i-servo motor iyajikeleza xa kukho igalelo lesignali yokulawula, kwaye iyayeka xa kungekho mqondiso wesignali. Ngokutshintsha isignali yokulawula kunye nesigaba (okanye i-polarity), isantya kunye nesalathiso se-servo motor sinokutshintshwa. I-rotor ngaphakathi kwe-servo motor yimagnethi esisigxina. Umbane wesigaba sesithathu se-U / V / W esilawulwa ngumqhubi wenza intsimi ye-electromagnetic, kwaye i-rotor ijikeleza phantsi kwesenzo salo mhlaba wamagnetic.Ngexesha elifanayo, umqondiso wempendulo we-encoder oza kunye ne-motor uthunyelwa umqhubi, kwaye umqhubi uthelekisa ixabiso lengxelo kunye nexabiso elijoliswe kuyo ukulungisa i-angle yokujikeleza ye-rotor. Ukuchaneka kwe-servo motor kuchongwa kukuchaneka kwe-encoder (inani lemigca)
Umfaki khowudi
Ngenjongo ye-servo, i-encoder ifakwe i-coaxially kwi-motor output. I-motor kunye ne-encoder zijikeleza ngokulandelelana, kwaye i-encoder nayo iyajikeleza kanye xa injini ijikeleza. Ngexesha elifanayo lokujikeleza, umqondiso we-encoder ubuyiselwa kumqhubi, kwaye umqhubi uyagweba ukuba ngaba isalathiso, isantya, isikhundla, njl njl. ngokufanelekileyo.I-encoder idibaniswe ne-servo motor, ifakwe ngaphakathi kwe-servo motor
Inkqubo ye-servo yinkqubo yolawulo oluzenzekelayo eyenza ubungakanani obulawulwayo bemveliso efana nendawo, uqhelaniso, kunye nemeko yento ukulandela utshintsho olungenasizathu lwenjongo yegalelo (okanye ixabiso elinikiweyo). Ukulandelwa kwayo kwe-servo ikakhulu kuxhomekeke kwimibhobho yokubeka indawo, enokuqondwa ngokusisiseko ngolu hlobo lulandelayo: i-servo motor iya kujikeleza i-angle ehambelana ne-pulse xa ifumana i-pulse, ngaloo ndlela iqonda ukufuduka, kuba i-encoder kwi-servo motor nayo iyajikeleza, kwaye inekhono lokuthumela Umsebenzi we-pulse, ngoko lonke ixesha i-servo motor ijikeleza i-angle, iya kuthumela inani elihambelanayo lee-pulses, elivakalisa ii-pulses ezifunyenwe yi-servo motor, kunye nokutshintshana ngolwazi kunye nedatha, okanye iluphu evaliweyo. Zingaphi iipulse ezithunyelwa kwi-servo motor, kwaye zingaphi iipulse ezifunyenwe ngexesha elifanayo, ukwenzela ukuba ukujikeleza kwemoto kunokulawulwa ngokuchanekileyo, ukuze kufezekiswe indawo echanekileyo. Emva koko, iya kujikeleza ixeshana ngenxa ye-inertia yayo, kwaye emva koko iyeke. I-servo motor kufuneka imise xa imisa, kwaye ihambe xa kuthiwa ihambe, kwaye impendulo ikhawuleza kakhulu, kwaye akukho kulahleka kwesinyathelo. Ukuchaneka kwayo kunokufikelela kwi-0.001 mm. Kwangaxeshanye, ixesha lokuphendula eliguquguqukayo lokukhawuleziswa kunye nokwehliswa kwesantya se-servo motor nalo lifutshane kakhulu, ngokubanzi phakathi kwamashumi eemillisecond (1 umzuzwana ulingana ne-1000 millisecond)Kukho iluphu evaliweyo yolwazi phakathi komlawuli we-servo kunye nomqhubi we-servo phakathi isignali yokulawula kunye nengxelo yedatha, kwaye kukho kwakhona isignali yokulawula kunye nengxelo yedatha (ethunyelwe kwi-encoder) phakathi komqhubi we-servo kunye ne-servo motor, kwaye ulwazi phakathi kwabo lwenza i-loop evaliweyo. Ke ngoko, ukuchaneka kolungelelwaniso lolawulo kuphezulu kakhulu
