Lub Torque Wrench ua haujlwm li cas?
Vim li cas kuv thiaj li xav tau lub torque ciaj ntswj thiab tsis yog ib lub spanner xwb?
Qee cov fasteners, xws li cov nyob rau hauv lub tsheb, yuav tsum muaj ib tug nruj tus nqi rau kev nyab xeeb. Yog tias koj tsis siv qhov tseeb ntawm torque, cov txiv ntoo thiab bolts tuaj yeem xoob. Tab sis yog tias koj siv lub zog ntau dhau, koj tuaj yeem ua rau cov xov puas. Rau cov ntawv thov uas cov txiv ntseej thiab bolts yuav tsum tau nruj thiab ruaj ntseg, xws li lub log nruj, lub torque ciaj ntswj yog cov cuab yeej rau txoj haujlwm.
Lub torque wrench tiv thaiv koj los ntawm kev nruj nruj uas tuaj yeem ua rau kev puas tsuaj los yog ua kom nruj uas yuav ua rau lawv xoob.
Muaj qhov tseeb torque teeb yog qhov tseem ceeb rau kev txhim kho kev nyab xeeb thiab kev ua haujlwm ntawm cov khoom siv. Torque wrenches yuav tsum tsis txhob siv los loosen bolts, tsuas yog kom nruj.
Teem lub Torque Wrench
Torque yog lub zog sib hloov. Nws yog ntsuas hauv lb·ft (pound-foot), lb·in (pound inch), lossis N·m (newton meter). Lub torque wrench yuav muaj cov cim sib txawv ntawm txhua sab. Feem ntau yog ko taw phaus (lb.ft).
Txhua lub tsheb muaj qhov sib txawv torque specification los ntawm cov chaw tsim khoom. Qhov no tuaj yeem pom hauv lub tsheb phau ntawv.
Koj tuaj yeem hloov qhov chaw ntawm koj lub torque wrench kom nce lossis txo lub zog. Txhawm rau ua qhov no, tsuas yog tig tus kov clockwise rau ntau lub zog los yog tiv thaiv clockwise kom txo nws. (Ntxiv rau qhov no tom qab).
Txhawm rau qhia ntau npaum li cas torque raug siv, cov cuab yeej feem ntau yuav muaj qhov ntsuas lossis tso saib nyob ntawm tus qauv.
Torque wrenches tuaj nyob rau hauv ntau hom thiab ntau thiab tsawg nrog txawv torque ntau yam. Qhov loj tshaj plaws yog 1/2 "square drive, tab sis dua qhov no yog nyob ntawm lub fastener thiab daim ntawv thov.
Yuav Siv Lub Torque Wrench li cas
Kauj ruam los ntawm kauj ruam
Thawj kauj ruam koj xav siv thiab teeb tsa koj lub torque ciaj ntswj yog nrhiav kom paub tus nqi torque. Raws li tau hais los saum toj no, qhov no tuaj yeem pom nyob rau hauv cov neeg siv phau ntawv, lossis qee zaum hauv online. Nco ntsoov tias koj tab tom saib qhov ntsuas qhov tseeb ntawm koj lub torque ciaj ntswj raws li feem ntau muab rau koj lb·ft ntawm ib sab thiab lb·ft lossis Nm ntawm lwm qhov.
Loosen lub pob qhov rooj nyob rau hauv qab ntawm lub torque wrench. Qhov no yuav tso cai rau tus kov tig rov qab thiab tawm mus
Yog tias qhov xav tau torque yog 100 lb.ft, koj xav tig tus kov kom txog thaum '0' ua tau raws li 100 lb.ft kab
Tighten lub ntsuas phoo rov qab thaum koj tau teeb tsa koj qhov xav tau torque los xauv nws rau hauv qhov chaw. Cov kauj ruam no tseem ceeb heev
Muab koj lub qhov (socket) tso rau ntawm lub torque wrench
Muab nws tso rau ntawm lub txiv ntoo
Tsuas tuav tus kov thiab zawm
Thaum koj hnov ib nias, qhov xav tau torque tau ntsib
Cov ntsiab lus yuav tsum nco ntsoov thaum siv thiab ua haujlwm nrog torque wrenches:
Thaum koj hnov qhov nias, tsis txhob zawm lub txiv ntoo ntxiv lawm. Ib qho nias ntxiv yog txhua yam uas xav tau rau lub fastener kom overtightened.
Tsis txhob siv koj lub torque ciaj ntswj kom nruj lub fastener. Hloov chaw, ua haujlwm feem ntau nrog koj lub ratchet thiab tom qab ntawd ua tiav nrog koj lub torque ciaj ntswj kom nws mus rau qhov xav tau torque.
Tej zaum koj yuav tau siv qhov txuas ntxiv yog tias lub qhov (socket) tsis tob txaus
Ib txwm tuav koj lub torque wrench nrog kev saib xyuas. Khaws rau hauv nws cov ntaub ntawv muab thaum tsis siv. Qhov no tiv thaiv nws los ntawm knocks thiab pob uas yuav cuam tshuam rau nws cov kev ua tau zoo, raug thiab calibration.
Thaum koj khaws koj lub torque wrench, loosen nws mus rau qhov chaw qis tshaj. Qhov no yuav pab kom nws nyob twj ywm hauv calibration ntev dua vim tias tsis muaj zog ntau npaum li lub caij nplooj ntoos hlav.
Calibrating lub Torque Wrench
Ua ntej siv lub torque ciaj ntswj, nws yog ib qho tseem ceeb heev uas nws tau raug calibrated.
Torque wrenches yuav tsum tau ntsuas tsis tu ncua kom ntseeg tau tias lawv khaws cov txiaj ntsig tau raug thiab txhim khu kev qha. Qhov no yuav tsum tau ua los ntawm tus kws tshaj lij. Tsis muaj lub sijhawm teem sijhawm raws li qhov yuav tsum tau ntsuas koj tus ciaj ntswj ntau npaum li cas raws li nws nqes mus rau ntau npaum li cas cov cuab yeej siv, txawm hais tias qhov kev pom zoo yog ib xyoos ib zaug lossis txhua 5000 clicks.
Hom Torque Wrench
Muaj ntau yam sib txawv torque wrenches muaj nyob rau hauv khw. Peb tau hais txog peb 3 qhov kev nyiam thiab lawv siv hauv qab no.
Nyem torque wrenches:
Nyem torque wrenches nyob hauv yuav luag txhua lub thawv cuab yeej. Lawv muaj lub caij nplooj ntoos hlav-loaded lever uas yog kho los ntawm twisting tus kov mus rau txoj cai qhov chaw thiab yuav ua rau ib tug nias lub suab thaum tus nqi ntawm torque yog mus txog. Thaum qhov xav tau torque qib tiav, lub zog tawg uas tsim lub suab nias.
Feem ntau nias hom yog ratcheting thiab tej zaum yuav siv rau zawm los yog loosening. Koj tsuas xav hnov 1 nias. Ib qho ntxiv thiab koj dhau nruj. Cov torque wrenches tuaj yeem yuav hauv ntau qhov ntau thiab tsawg thiab txwv torque. Lawv yog cov zoo heev rau siv nyob rau hauv nyuaj mus cuag tej cheeb tsam.
Digital torque wrenches:
Cov digital, lossis hluav taws xob torque wrenches ua haujlwm los ntawm lub ntsuas hluav taws xob yog li tsis txhob muaj qhov txav mus los. Lawv paub ntau npaum li cas twisting quab yuam yog siv thiab qhia rau tus neeg siv ntawm cov zaub. Tsuas yog hu rau hauv qhov chaw torque koj xav tau thiab nws yuav beep los yog lub teeb yuav flash, los yog ob qho tib si, thaum lub torque raug mus txog.
Qee qhov digital torque wrenches tseem tuaj yeem suav nrog lub cim xeeb kom txuag kev nyeem ntawv.
Beam torque wrenches:
Beam torque wrenches yog qee qhov yooj yim siv thiab yog cov qauv yooj yim tshaj plaws ntawm torque wrench. Lawv feem ntau yog siv rau hauv daim ntawv thov nruj nruj, tshwj xeeb tshaj yog nyob rau hauv tsheb. Lawv muaj 2 kab teeb - thawj zaug yog lub zog siv los siv lub zog rau lub fastener tau nruj thiab qhov thib ob tsuas yog txuas rau ntawm ib kawg ntawm lub taub hau thiab ua haujlwm raws li qhov taw qhia beam.
Peb sab saum toj xaiv rau torque wrench hom yog Norbar. Mus yuav khoom ntawm Toolstop.
Tam sim no koj yuav tsum paub txog torque wrenches, yuav ua li cas teeb tsa thiab ua haujlwm thiab qhov twg koj yuav tsum xaiv rau. Torque wrenches yog cov cuab yeej tseem ceeb hauv ntau qhov kev lag luam. Toolstop yog koj qhov chaw nres tsheb rau kev tshaj lij torque wrenches.
