Self-sliding tov rau lub chim ntawm ib tug biological microscope
Thawj kauj ruam: siv ob txhais tes los tuav ob lub coarse adjustable handwheel, txheeb ze quab yuam nruj. Txhawm rau saib seb qhov teeb meem puas tuaj yeem daws tau, yog tias qhov teeb meem tsis tuaj yeem daws tau, nws yog ib qho tsim nyog yuav tsum tau siv ib qho tshwj xeeb ob-kem phaj tes mus rau qhov ntxhib hloov ntawm lub handwheel screwed down, ntxiv ib qho kev sib txhuam, lub handwheel tightened, yog kev sib hloov yog qhov nyuaj heev, tom qab ntawd ntxiv cov yeeb yaj kiab kev sib txhuam yog tuab heev, tuaj yeem hloov nrog nyias nyias. Rau kev sib hloov ntawm tes tsis yog qhov nyuaj, yooj yim txav mus los ntawm lub lens chim, thiab tsis swb ntawm nws tus kheej yuav yeej. Kev sib txhuam zaj duab xis tuaj yeem siv cov duab thaij duab pov tseg thiab tsawg dua 1 hli tuab daim ntawv yas nrog lub perforator punch.
Cov kauj ruam thib ob: xyuas qhov kev hloov kho ntxhib ntawm lub tes tuav lub zog thiab daim iav raj ntawm lub khib meshing raws li txoj cai. Lub nce thiab nqis ntawm daim iav chim yog tsav los ntawm lub iav kom tiav lub khib. Iav thiab khib ntawm qhov zoo tshaj plaws mesh xeev nyob rau hauv txoj kev xav yog khib ntawm cov kab ntsuas thiab iav index voj voog tangent. Nyob rau hauv lub xeev no, lub iav rotates yooj yim, thiab hnav ntawm lub khib yog minimised.
Niaj hnub no, muaj kev xyaum tsis ncaj ncees lawm ntawm kev ntxiv shims qab lub khib kom lub khib presses nruj nreem tiv thaiv lub iav kom tsis txhob lub iav raj ntawm zawv zawg. Nyob rau lub sijhawm no, qhov ntsuas kab ntawm lub khib cuam tshuam qhov ntsuas lub voj voog ntawm lub iav, thiab cov lus qhia hniav ntawm lub iav thiab khib yog nias rau ib leeg cov hauv paus hniav. Raws li lub zog tig, kev sib tsoo hnyav tshwm sim ntawm lawv. Cov khib nyiab yog ua los ntawm tooj liab thiab cov iav yog ua los ntawm cov hlau. Yog li ntawd, kev sib tsoo ntawm ib leeg yuav hnav tawm cov hniav ntawm cov khib nyiab, thiab ntau daim tooj liab yuav raug tsim tawm ntawm cov iav thiab khib. * Tom qab ntawd, lub khib yuav hnyav hnyav thiab siv tsis tau. Yog li ntawd, koj yuav tsum tsis txhob tsa lub khib los tiv thaiv lub iav raj los ntawm zawv zawg. Tib txoj hauv kev los daws qhov teeb meem ntawm lub thoob plam ntawm nws tus kheej yog txhawm rau ua kom muaj kev sib txhuam ntawm qhov sib txawv ntawm lub log thiab lub tes tsho eccentric. Muaj ib qho kev zam rau txoj cai no, thiab qhov ntawd yog thaum lub indexing kab ntawm lub khib tawm ntawm theem nrog lub voj voog indexing ntawm lub iav. Nyob rau hauv cov ntaub ntawv no, thaum lub coarse hloov handwheel yog tig, tib yam tshwm sim ntawm idling thiab slipping yuav tshwm sim, cuam tshuam rau lub nce thiab nqis ntawm daim iav raj. Yog hais tias qhov no los ntawm kev kho qhov ntxhib hloov handwheel eccentric bushing, tsis tuaj yeem kho cov iav thiab khib meshing nrug. Tsuas yog nyob rau hauv khib thiab pinion tom qab padding daim ntawv tsim nyog los daws qhov teeb meem. Ntxiv shims los kho cov iav thiab khib meshing nrug ntawm tus qauv yog: tig lub coarse adjustment handwheel tsis yooj yim, tab sis kuj tsis ua haujlwm.
Tom qab kho qhov kev ncua deb, ntxiv qee cov roj nruab nrab ntawm lub iav thiab khib. Cia lub tog raj kheej txav nce thiab nqis ob peb zaug uas tuaj yeem ua tau. Thaum kawg, peb yuav tsum tau muab lub tes tsho eccentric ncej ntawm ob compression screws nruj. Txwv tsis pub, thaum koj tig lub coarse adjustment handwheel, lub tes tsho eccentric ncej yuav ua raws li qhov kev sib hloov, thiab cov khib nyiab yog jammed, yog li ntawd daim iav tsis tuaj yeem txav mus los. Yog tias koj tig lub log nrog lub zog ntau dhau, lub khib thiab lub tes tsho eccentric yuav puas. Yog hais tias lub eccentric bushing tseem tig tom qab zawm lub compression ntsia hlau, nws yog vim lub qhov ntawm lub compression ntsia hlau tsis nruj. Qhov no yog vim lub fact tias cov threads ntawm cov ntsia hlau qhov ntawm lub compression screws tsis tau raug hloov. Vim tias cov tuam txhab hloov cov xov los ntawm lub tshuab, feem ntau muaj ib lossis ob lub xov tsis hloov hauv qhov chaw. Lub sijhawm no, txawm tias cov ntsia hlau compression tsis ntsia rau hauv qhov chaw, eccentric bushing yuav tsis raug nias. Pom tau tias qhov tsis ua haujlwm zoo li no, tsuav yog M3 tapping ntsia hlau qhov xov tuaj yeem rub los ntawm kev daws teeb meem. Kuv siv txoj kev no los daws qhov teeb meem ntawm 30 teeb ntawm biomicroscope eccentric ncej tes tsho nrog kev sib hloov ntawm kuv lub tsev kawm ntawv.
