Inkqubo yojikelezo lweisetyhulaukunithaumatshiningokusisiseko yintshukumo equlathe isindululo sesetyhula esijikeleze iasi esembindini, enamalungu amaninzi afakelweyo kwaye asebenza kumbindi omnye. Emva kwexesha elithile lokusebenza kwindawo yokuluka, umatshini ufuna ukulungiswa okubanzi. Owona msebenzi uphambili kule nkqubo awubandakanyi ukucoca oomatshini kuphela kodwa kwanokutshintsha iindawo ezonakeleyo. Ugxininiso oluphambili kukuhlola ukuchaneka kofakelo kunye nokuchaneka kokusebenza kwecandelo ngalinye ukujonga ukuba ngaba kukho naluphi na utshintsho okanye ukuphambuka ngaphaya koluhlu lokunyamezela oluchaziweyo. Ukuba kunjalo, amanyathelo okulungisa kufuneka athathwe.
Uhlalutyo lunikezelwa ngezizathu ezikhokelela ekungaphumeleli ekufezekiseni uluhlu olufunekayo lwesetyhula kunye ne-flatness kumacandelo afana neesirinji kunye namacwecwe.
Ukujikeleza kwe-pulley kwahluleka ukuhlangabezana nokuchaneka okufunekayo.
Umzekelo, ukunxitywa kweendawo zokubeka iigrooves phakathi kweipleyitikunye nepuli (exhaphake ngakumbi kwimowudi yokutyibilika ekhubekisayo), enokukhokelela ekukhululekeni okanye ekunxityweni kwengoma yesikhokelo socingo okanye umkhono ophakathi ngaphakathi kwesitya esikhulu somatshini esinamacala amabini, zonke zinokukhokelela ekungakwazini ukufezekisa ukuchaneka okufunekayo Ukujikeleza kwe-cylinder. Indlela yokuhlola imi ngolu hlobo lulandelayo: beka umatshini kwindawo emileyo, beka isalathisi segeyiji yokucofa kwindawo yesibambi sediski ene-toothed (ukuba izikrufu ezikhusela inaliti okanye idiski kwisibambi senaliti esinamazinyo okanye igubu yenaliti khange ikhululwe, isalathisi sinokubekwa kwindawo yesilinda yenaliti okanye idiski), kunye nesitulo sokulinganisa ukucofa.i-adsorptionkumatshini ongenakujikeleza kunye ne-disc ene-toothed okanye i-drum yenaliti, njengesitya esikhulu okanye imbiza, njengoko kuboniswe kuMzobo 1 kunye nomfanekiso 2. Ngokunyanzeliswa ngamandla kwe-chuck okanye i-pin plate tray, jonga utshintsho kwi-dial. uluhlu lwesalathiso segeyiji. Ukuba iwela ngaphantsi kwe-0.001 mm, ibonisa ukuba ukuchaneka kokusebenza kwe-chuck kuhle kakhulu. Xa iphakathi kwe-0.01 mm kunye ne-0.03 mm, ukuchaneka kulungile; xa idlula i-0.03 mm kodwa ingaphantsi kwe-0.05 mm, ukuchaneka kuphakathi; kwaye xa ingaphezulu kwe-0.05 mm, ukuchaneka kokusebenza kwe-chuck iba yinto ephantsi. Ngeli xesha, ukulungelelanisa ukujikeleza kwepleyiti yephini ukuya ngaphakathi kwe-0.05 mm kuya kuba nzima kakhulu okanye kungenakwenzeka, kufuneke ukubuyisela ukuchaneka kokusebenza kwe-chuck okanye itreyi kuqala. Indlela yokubuyisela ukuchaneka ekusebenzeni kuya kuhluka ngokuxhomekeke kwizakhiwo ezahlukeneyo kunye neendlela zokujikeleza kwe-pulley, engaphaya kobubanzi beli nqaku.
Xa umphezulu woqhagamshelwano phakathi kwee-cogs ezilishumi elinambini kunye nepistoncylindricalazilingani okanye xa umphezulu woqhagamshelwano phakathi kwepleyiti yephini kunye nesiseko ungalingani, xa kusenziwa ucingo lokuxinana olujikelezileyo, izithuba phakathi kwepiston.cylindrical, i-pin plate, i-disc, kunye nesiseko ziya kucinezelwa kunye, kubangela ipistoncylindricalkunye nepleyiti yephini ukuze ingene kwi-elastic deformation. Ngenxa yoko, ukujikeleza kuya kuphambuka kunyamezelo olufunekayo. Ngokwenyani, xa izikrufu ezigcinayo zikhululwa kancinci, ukujikeleza kwe-chuck kunye ne-spindle kunokulungelelaniswa ngokulula ukuya ngaphakathi kwe-0.05mm, kodwa xa kujongwa ukujikeleza kwakhona emva kokutshixa izikrufu, kudlula uluhlu olufunekayo olungaphantsi kwe-0.05mm umda obalulekileyo. Amanyathelo okujongana nalo mba alandelayo
Khululeka izikrufu eziqiniweyo, hlengahlengisa isirinji kunye nepleyiti yenaliti ngokurhabaxa ukuba imile ngendlela engqukuva, uqinisekise ukuba ingaphantsi kwe-0.03 mm ububanzi. Khulula intloko yegeyiji, beka intloko yegeyiji kungqameko okanye kumphezulu wentamo yesilinda, okanye ipleyiti yenaliti, jikelezisa isikrufu ngasinye de isalathisi sijonge ezantsi, khusela izikrufu, jonga utshintsho kwinaliti yokulinganisa, ukuba ukufunda kuyancipha, kubonisa ukuba kukho isithuba phakathi kwe-cylinder, ipleyiti yenaliti, ivili legiya okanye isiseko.
Njengoko isalathisi kwigeyiji sitshintsha, faka izikhewu ezityebileyo ezifanelekileyo phakathi kwezikrufu zokuqinisa macala omabini, tshixa izikrufu kwakhona, kwaye ujonge utshintsho kwisalathisi de ilungelelaniswe kutshintsho olungaphantsi kwe-0.01 mm emva kokutshixa izikrufu. Ngokufanelekileyo, akufanele kubekho utshintsho konke konke. Qhubeka uqinisa i-screw elandelayo ngendlela elandelelanayo, ukuphinda inkqubo de i-bolt nganye yokubopha ibonise utshintsho kwi-pointer engaphantsi kwe-0.01 mm emva kokuqiniswa. Oku kuqinisekisa ukuba akukho msantsa phakathi kwesirinji, ipleyiti yenaliti, kunye negiya okanye isiseko sokuxhasa apho izikrufu ziqinisiwe. Kuyaphawuleka ukuba emva kokuba indawo nganye ye-screw ihlengahlengiswe, ngaphambi kokuba uqhubele phambili kwi-screw elandelayo, kufuneka ikhululwe ukuze kuqinisekiswe ukuba i-syringe kunye nepleyiti yenaliti zihlala zikwimeko ekhululekile kuyo yonke inkqubo yokulungelelanisa. Jonga ukuba tyaba kwesirinji kunye nepleyiti yenaliti; ukuba isalathisi sitshintsha ngaphezu kwe-0.05 mm, faka i-shims ukuyilungisa ngaphakathi kwe-± 0.05 mm.
Khulula intloko yetephu ozibethayo kwaye uyibeke kwicala lesirinji okanye kumda wechuck. Lungisa utshintsho lwesetyhula yepleyiti yesirinji ngokungekho ngaphezulu kwe-0.05 mm kwaye utshixe izikrufu.
Ukuchaneka kweisinki,camipleyiti yesiseko okanye isakhelo se-shuttle asikwazi ukuhlangabezana nemigangatho. Uhlobo olunjalo lwenxalenye yomatshini ludla ngokuba ngumthwali wecamisiseko, ogama flat kunye neemfuno i-angle imbuyekezo azikho phezulu njengoko ipleyiti yenaliti okanyeinaliti cylinder. Nangona kunjalo, ngenxa yohlengahlengiso lwabo ngexesha lemveliso ekuphenduleni utshintsho kwimveliso, baya kulungelelanisa phezulu nangaphantsi okanye ngakwesobunxele nasekunene, kunokuba bafane nepleyiti yenaliti okanye i-cylinder yenaliti, enokuthi ihlengahlengiswe kanye kwaye ihlale ingatshintshi ngaphandle kokuba ithathelwe indawo. Ke ngoko, ngexesha lohlengahlengiso, ukufakwa kunye nokulungelelaniswa kwezi bhloko kubaluleke kakhulu. Ngezantsi, siya kwazisa indlela ethile ngomzekelo weBhodi yokuBulala koBomi, 2.1 Ukulungelelanisa iBalance.
Xa umgangatho wetreyi uphelelwe ukunyamezela, qala ngokukhulula izikrufu kunye neebhloko zokubeka kwindawo yetreyi.rii-acks, kunye nezikali ze-adsorption ezihleli kwiisirinji,beka intloko yesalathisi kwincam yetreyi, jikelisa umatshini kwitreyi ethile, kwaye ukhusele iibholithi eziqhoboshela itreyi kwitreyi.ikram. Jonga utshintsho kwisalathisi. Ukuba kukho naluphi na utshintsho, lubonisa ukuba kukho i-gap phakathi kwe-bracket kunye ne-tray, efuna ukusetyenziswa kwe-shims ukuyikhusela. Xa i-screw yokutshixa iqinisiwe, ukuhluka kumlinganiselo ngu-0.01 mm kuphela, kodwa kuphawuleka ngokukodwa ukuba ngenxa yendawo enkulu yoqhagamshelwano phakathi kwesibiyeli kunye netreyi, kunye nenyaniso yokuba isalathiso sesalathisi asihambelani ngokufanayo. iradiyasi njengentloko yetafile, xa isikrufu sokutshixa siqiniswa, nangona kukho umsantsa, utshintsho kufundo lwesalathisi lusenokungasoloko luncipha, kodwa lusenokuba lunyuko. Ubungakanani bentshukumo yesalathisi bubonisa ngokuthe ngqo indawo yesithuba phakathi kwesibiyeli kunye netreyi, njengoko kubonisiwe kumfanekiso 3a, apho igeyiji yokucofa iya kufunda ixabiso elikhulu kwisikrufu sokutshixa. Ukuba unyawo lukwindawo eboniswe kuMfanekiso 3b, ufundo lwetachometer yesikrufu sokutshixa luya kuncipha. Ngokubona ukuhluka kokufunda, umntu unokugqiba indawo ye-gap kwaye asebenzise imilinganiselo efanelekileyo ngokufanelekileyo.
Ukulungelelaniswa kokungqukuva kunye nokuthambeka kweijezi ephindwe kabiniumatshini
Xa ububanzi kunye flatness leijezi ephindwe kabiniumatshiniukudlula uluhlu oluqhelekileyo, ulungelelwaniso kufuneka lwenziwe kuqala ukuze kuqinisekiswe ukuba iibheringi kunye neepuli ngaphakathi kwe-cylinder eyintloko azikhululekanga okanye zibe ne-looseness ngaphakathi kwemida eyamkelekileyo. Xa oku kuqinisekisiwe, uhlengahlengiso lunokuqhubeka ngokufanelekileyo. Ngokuhambelana nenqanaba
Faka iyunithi yokuzimela ngokwemiyalelo enikeziweyo, kwaye ukhulule zonke iibholiti ezinkulu ezikhuselayo. Ukutshintshela ipleyiti yepivot kunyawo olusembindini lwenkxaso, qinisa isikrufu ngasinye ngokukhuselekileyo, jonga utshintsho kwigeyiji yokucofa ukuze uqinisekise ukuba kukho nawuphi na umsantsa phakathi konyawo lwenkxaso olusembindini kunye netripodi enkulu, kwaye ukuba kunjalo, indawo ekuyo echanekileyo. Umgaqo ufana nalowo uqeshwe ekuhlalutyeni utshintsho kwi-dial reading xa kulungiswa inqanaba letreyi, apho izikhewu zizaliswe ngama-spacers. Emva kohlengahlengiso ngalunye lwendawo yesikrufu, phumla esi jinja phambi kokuba uqhubeke nohlengahlengiso lwesikrufu esilandelayo de ukuqiniswa kwesikrufu ngasinye kubangela utshintsho ekufundeni iwotshi ngaphantsi kwe-0.01 yeemilimitha. Wakuba ugqibile lo msebenzi, jikelisa umatshini ngokupheleleyo ukujonga ukuba umgangatho ungaphakathi kweeparamitha eziqhelekileyo. Ukuba idlula uluhlu oluqhelekileyo, lungisa ngeeshim.
Emva kokulungelelaniswa kwe-concentricity, i-micrometer iya kufakwa ngokwemfuno. Ukuhlola ukungqukuva koomatshini ukufumanisa ukuba ngaba uwela ngaphandle kweeparamitha eziqhelekileyo, ulungelelwaniso lunokwenziwa kusetyenziswa izikrufu zokuhlenga-hlengisa umatshini ukuze ubuyiselwe phakathi koluhlu. Kubalulekile ukuba ubeke ingqalelo ekusebenziseni izikrufu, njengokuba kusetyenziswa iibhloko zokubeka indawo yetreyi. Umntu akufuneki atyhale ngenkani umkhono osembindini endaweni yakhe esebenzisa izikrufu, njengoko oku kunokubangela ukonakala kweelastiki koomatshini. Endaweni yoko, sebenzisa izikrufu zokulungisa ukuhambisa umkhono ophakathi kwindawo owufunayo, emva koko ukhulule izikrufu kwaye ufunde umlinganiselo kwigeyiji. Emva kokulungelelanisa, izikrufu zokutshixa kufuneka zibambelele kumphezulu wemikhono esembindini, kodwa akukho mandla kufuneka asetyenziswe kuwo. Isishwankathelo, akukho xinzelelo lwangaphakathi kufuneka lwenziwe emva kokuba uhlengahlengiso lugqityiwe.
Ekulungiseni ukugxila, kunokwenzeka ukuba ukhethe amanqaku amathandathu e-diagonal njengeendawo zokubhekisela, kuba abanye oomatshini babonisa intshukumo ye-eccentric ngenxa yokuguga, okubangela ukuba iitrajethi zabo zifane ne-ellipse kunokuba isangqa esigqibeleleyo. Ngethuba nje umahluko kufundo oluthathiweyo luwela phakathi koluhlu olwamkelekileyo, lunokuthathwa njengokuhlangabezana nomgangatho. Kodwa xa umphetho ugqwethekile ngenxa yeipleyiti's deformation, eyenza umendo wayo wentshukumo ufane neellipse, kufuneka kuqala ibe neipleyiti'sibunjwe ngokutsha ukuphelisa ukugqwetheka, ngaloo ndlela ibuyisela indlela yokuhamba yerim kwimilo esesangqa. Ngokufanayo, ukutenxa ngequbuliso ukusuka kwimeko yesiqhelo kwindawo ethile kunokuchazwa njengesiphumo sokunxiba okanye ukuguqulwa kwepuli. Ukuba kungenxa deformation yeipleyiti's, ukuguqulwa kufuneka kupheliswe; ukuba kungenxa yokunxiba, kuya kufuna ukulungiswa okanye ukutshintshwa ngokuxhomekeke kubunzima.
