Uma wakha ukusethwa okunembile—kungakhathaliseki ukuthi kuyi-lab fixture, i-laser alignment jig, noma isiteshi sokuhlola ukukhiqiza okugcwele—isigaba esiqondile osikhethayo sinquma cishe yonke into. Sibeka umkhawulo wakho wokunemba, umthwalo wakho wokulungisa, nokuthi uhlelo luzogcina isikhathi esingakanani ukusebenza kwalo kokuqala. Futhi ifoloko lokuqala endleleni livame ukwehlela kulokhu: ingabe usebenzisa isilayidi sedovetail, noma utshala imali ekwakhiweni kwe-cross roller bearing?
Besilokhu sikhiqiza izigaba zokubeka ngesandla, izigaba eziqondile eziwela ngama-roller, kanye namapulatifomu okuqondisa okuzenzakalelayo iminyaka engaphezu kweyisishiyagalolunye. Phakathi naleso sikhathi, siqondise amakhulu onjiniyela nabathengi ngalesi sinqumo. Awukwazi ukukwenza ngeshidi lemininingwane kuphela—udinga ukuqonda okucacile, okusebenzayo kokuthi lezi zindlela ezimbili zokuqondisa ziziphatha kanjani emavikini, ezinyangeni, neminyaka yokusetshenziswa kwangempela.
Yilokho kanye okwenziwa yilo mhlahlandlela. Sizohamba phakathi komehluko wolimi olulula, sabelane ngezinombolo zangempela kanye nedatha yokuhlola, futhi sikusize uphendule umbuzo owodwa oyinhloko.
Ukuqhathaniswa Okuningiliziwe Kwe-Linear Stage Bearing Phakathi Kwama-Dovetail Slides nama-Cross Roller Bearings Kukuthinta Kanjani Ukuzinza Kwesikhathi Eside Kwe-Manual Positioning Stage Yakho?
Ake sikuchaze kahle.
Iyini Isiteji Sokushelela Umsila We-Dovetail?
Cabanga ngesilayidi se-dovetail njengomzila omise okwe-wedge kanye nenqola ehambisanayo efana ne-wedge. Izindawo ezine-engile ziyadonsana, ngokuvamile nge-gib strip elungisekayo. Leyo geometry ye-wedge idala indawo enkulu yokuxhumana. Indawo yokuxhumana eningi isho umthamo omkhulu womthwalo kanye nokumelana okunamandla nokushaqeka nokudlidliza. Kungumklamo olula, ovivinywe isikhathi eside.
Isigaba esivamile sokubeka ngesandla esakhelwe kumaslayidi e-dovetail singase siphathe ama-N angu-200 kuya kwangu-1000 ngaphandle kokujuluka. Ububanzi bokuhamba bungafinyelela kalula ku-150 mm, 200 mm, noma ngaphezulu. Ubona lezi zigaba ezindaweni zokufaka i-optics ezisindayo, amathuluzi ezimboni, kanye nemisebenzi yokulungisa lapho indawo inzima khona futhi izidingo zokuphindaphinda zilinganiselwe.
Kodwa kukhona ukuphikisana. Izindawo ezishelelayo zihlala zithintana ngokugcwele ngaso sonke isikhathi. Ngisho nasezindaweni zensimbi ecijile noma zensimbi ezigcotshwe ngokunemba, ukungqubuzana kuphakeme. Lokho kungqubuzana kungabangela ukushelela kwenduku—ukunyakaza okuncane kokuqala okukhawulela indawo enhle. Uma uzama ukusunduza isampula ngama-micron amabili, ukushelela kwenduku kungonakalisa usuku lwakho.
Sivivinye izigaba ze-dovetail elebhu yethu. I-dovetail slide eyenziwe kahle yensimbi ensimbi ivame ukukhombisa i-coefficient of friction engaba ngu-0.1 kuya ku-0.15 ngaphansi kokulayisha okulula. Lokho kubushelelezi emisebenzini eminingi, kodwa akusondeli nhlobo ekunyakazeni okuhlanzekile okutholayo ezintweni ezigoqayo.
Iyini Isigaba Esiqondile Se-Cross Roller?
Isigaba esiqondile se-cross roller sisebenzisa ama-roller asilinda awela ngama-degree angu-90 komunye nomunye, agijima phakathi kwama-V-rails amabili aqondile aphansi. I-roller ngayinye ithinta i-rail emgqeni. Ama-roller aqondiswa ngokushintshana, ngakho-ke eyodwa iphatha umthwalo ohlangothini olulodwa kanti elandelayo iphatha uhlangothi oluqondile. Umphumela uba ukuqina okuphezulu kakhulu kuzo zonke izinkomba zokulayisha, okuhambisana nokungqubuzana okuphansi kakhulu kokugoqa.
Esigabeni esivamile sokuma ngesandla esifakwe iziqondiso ze-cross roller, ukungqubuzana kuphansi kakhulu kunesilayidi se-dovetail. I-coefficient yokungqubuzana ingaba ngaphansi kuka-0.001 kuya ku-0.002. Lokho kusho ukuthi ukunyakaza kuzwakala kulula, kuvumelana, futhi kungenaso nhlobo isibambo sokunamathela. Ungenza ukulungiswa kwe-sub-micron cishe ngaphandle kokushintsha kwamandla enkinobheni.
Ukuqina kokuqina nakho kukhulu. Isigaba somugqa we-cross roller esilayishwe kahle sivame ukukhombisa ukufuduka ngaphansi komthwalo okuncane ngokuphindwe kathathu kuya kahlanu kunesigaba somugqa we-dovetail olingana nosayizi. Futhi ngenxa yokuthi ama-roller aqinile futhi ahambisana ngokunemba, ukunemba kokuhamba kuhlala kuqinile. Ukuqonda okuvamile kanye nokuba yisicaba esigabeni somugqa we-cross roller kuwela ngaphakathi kwe-1 µm kuya ku-2 µm ngaphezu kwe-100 mm yokuhamba. Esigabeni somugqa we-dovetail sobukhulu obufanayo, ungalindela i-5 µm kuya ku-10 µm.
Umkhawulo? Umthamo womthwalo wemvilophu ethile uvame ukuba phansi. Izigaba eziningi eziqondile ze-cross roller zisingatha i-100 N kuya ku-500 N. Ukuhamba kuvame ukuba kufushane—ngokuvamile ngaphansi kuka-150 mm—ngoba kunzima ukusekela ama-V-rails amade ngaphandle kokufaka ukuhambisana. Kodwa ngokubeka okufushane, okunembe kakhulu, kuyindinganiso yegolide.
