Nyob rau hauv precision kis systems, lubPob Ntsia Hlauthiab linear qhia rail yog ib khub ntawm cov neeg koom tes. Cov kev taw qhia kev tsheb ciav hlau tuav cov kev taw qhia thiab thauj khoom-cov kabmob, thaum lub ntsia hlau tuav tsav tsheb thiab qhov chaw. Ntau tus neeg siv zog los xaiv txoj kev tsheb ciav hlau tab sis tsis quav ntsej qhov sib txuam ntawm cov ntsia hlau, ua rau cov khoom siv tsis tu ncua "nco lub cim."
Xyoo tas los, ib tus neeg siv khoom siv peb lub tshuab xa tawm axis tsis tuaj yeem tau txais X-axis qhov tseeb nyob rau hauv ± 0.02mm txawm lawv sim ua dab tsi. Lawv xav tias cov kev taw qhia rails yog qhov teeb meem thiab hloov lawv nrog cov precision siab dua - tseem tsis tau txhim kho. Thaum peb kuaj xyuas, cov ntsia hlau yog C7 qib (kev ua yuam kev 0.05mm / 300mm), thaum cov lus qhia rail twb P qib. Cov ntsia hlau qhov tseeb tsis tuaj yeem khaws cia, txawm hais tias qhov kev taw qhia kev tsheb ciav hlau yog qhov tseeb.
Qhov ntawd yog ib rooj plaub classic ntawm cov neeg koom tes tsis sib haum. Niaj hnub no, cia peb tham txog ntau yam Pob Ntsia Hlau xaiv yuam kev, vam tias yuav pab tau koj khub no duo kom raug.
1. Lub Pob Ntsia Hlau Qhov Ntsuas Qhov Tseem Ceeb Tshaj Li Cas?
Thaum xaiv cov ntsia hlau, cov neeg feem coob saib tsuas yog "inch" thiab "lead." Qhov tseeb, ob peb lwm yam tsis muaj kev cuam tshuam ntau dua rau qhov raug thiab lub neej.
1. Qib raug (C0–C7)
Qib raug txiav txim qhov ua yuam kev. Cov lej me me txhais tau tias muaj qhov tseeb dua thiab tus nqi siab dua.
| Qib | Lead yuam kev (ib 300mm) | Tej kev siv |
|---|---|---|
| C7 | Tsawg dua los yog sib npaug li 0.05mm | General tuav, vuam, tsis tshua muaj tseeb positioning |
| C5 | Tsawg dua lossis sib npaug li 0.018mm | General CNC, milling tshuab, dispenser |
| C3 | Tsawg dua los yog sib npaug li 0.008mm | Precision machining chaw, grinders |
| C0/C1 | Tsawg dua lossis sib npaug li 0.003mm | Ultra-precision khoom, ntsuas ntsuas |
Kev xaiv txoj cai: Tus ntsia hlau qhov raug qib yuav tsum tsis txhob qis dua cov kev taw qhia rail qib. Yog tias cov lus qhia kev tsheb ciav hlau yog qib P (0.005mm / m), cov ntsia hlau yuav tsum yog tsawg kawg C5, zoo dua C3. Txwv tsis pub, qhov kev ua yuam kev ntawm cov ntsia hlau yuav noj cov lus qhia kev tsheb ciav hlau qhov tseeb.
2. Preload qib (Z0–Z3)
Preload tshem tawm backlash. Ib tug ntsia hlau tsis muaj preload yuav muaj "poob tsab ntawv tsa suab" thaum thim rov qab, ua rau qhov chaw tsis raug. Heavy preload (Z2 thiab saum toj no) yog tsim rau kev cuam tshuam kev thauj khoom tab sis ua kom kub nce. Rau cov khoom siv ceev ceev, xaiv qis lossis xoom preload.
3. Kev them nyiaj yug txoj kev
Yuav ua li cas cov ntsia hlau xaus yog tsau heev cuam tshuam rigidity. Tsau-taw muab qhov zoo tshaj plaws rigidity, zoo tagnrho rau kev mob stroke ntev thiab kev kub ceev; taag-txhawb yog ntau; tsau-dawb tsuas yog rau luv luv stroke ntsug axes.
2. Peb qhov teeb meem feem ntau
Pitfall 1: Mismatched ntsia hlau thiab qhia rail raug
Zoo li cov ntaub ntawv dhau los. Ntau tus neeg tsim khoom xaiv cov kev taw qhia kev tsheb ciav hlau ua ntej thiab tom qab ntawd yuav cov ntsia hlau "tawm ntawm lub txee" raws li kev xav tom qab. Qhov tshwm sim: qhia rail 0.005mm, ntsia hlau 0.05mm - qhov tseeb raug rub los ntawm cov ntsia hlau. Ib qho zoo Pob Ntsia Hlauyuav tsum nyob rau hauv ib tug par nrog rau cov kev taw qhia rail nyob rau hauv raug. Cov lus qhia: yog tias cov ntawv qhia kev tsheb ciav hlau yog qib P, xaiv yam tsawg kawg C5 ntsia hlau, nyiam dua C3.
Pitfall 2: Tsis quav ntsej qhov nrawm nrawm
Yog hais tias ib tug ntsia hlau tig ceev heev, nws yuav resonate. Ntau tus neeg siv suav load tab sis tsis ceev. Piv txwv li, 25mm txoj kab uas hla, 1500mm ntev ntsia hlau nrog ruaj-txhawb mounting muaj qhov ceev ceev ntawm txog 2000rpm. Yog tias cov cuab yeej xav tau 2500 rpm, nws yuav nkag mus rau thaj chaw resonance, ua rau raug poob thiab suab nrov. Nco ntsoov xyuas qhov ceev ceev thaum xaiv; yog tias xav tau, nce txoj kab uas hla lossis hloov mus rau kev txhawb nqa ruaj khov. Xaiv txoj kab uas hla thiab kev txhawb nqa rau aPob Ntsia Hlauyog tus yuam sij kom tsis txhob resonance.
Pitfall 3: Tsis-coaxial installation
Yog hais tias cov ntsia hlau tsis sib npaug rau cov kev taw qhia rail, los yog lub rooj zaum ntawm cov txiv ntoo thiab cov slider mounting nto tsis coplanar, lateral rog yuav tshwm sim. Lateral rog ua kom cov txiv ntoo hnav thiab tuaj yeem khoov lub hau. Tom qab kev teeb tsa, tig lub ntsia hlau los ntawm tes. Yog hais tias tsis sib xws los yog muaj cov ntsiab lus sticking, cov axes tsis sib haum. Siv lub ntsuas ntsuas los ntsuas qhov sib npaug (tsawg dua lossis sib npaug ntawm 0.02mm / m). Ib qho zooPob Ntsia Hlautsis tsuas yog yuav tsum tau high precision - nws kuj yuav tsum tau sib npaug ntawm qhov tseeb installation.
3. Lubrication thiab Kev Kho: Lub Ncauj Killer ntawm Screws
Cov npas thiab kev sib tw ntawm Pob Ntsia Hlau muaj qhov sib cuag, ua rau lawv nkag siab zoo rau lubrication. Lub lubrication tsis txaus ua rau muaj kev sib txhuam thiab qhov kub thiab txias, ua rau kom hnav sai lossis qaug dab peg.
Lubrication cov lus pom zoo:
- Rau kev ceev ceev, siv lithium roj (NLGI 1-2), rov ntxiv txhua 3-6 lub hlis.
- Rau kev ua haujlwm nrawm nrawm, siv roj (ISO VG32-68) nrog lub tshuab lubrication tsis siv neeg.
- Kev tiv thaiv plua plav yog qhov tseem ceeb - plua plav nkag mus rau hauv txoj kev sib tw yuav ua rau cov txiv ntoo ua tsis tiav ntxov.
Tsis tas li ntawd, tsis tu ncua xyuas backlash. Siv lub ntsuas dial ntawm tus ntsia hlau kawg thiab txav lub rooj ua haujlwm rov qab los - qhov sib txawv ntawm kev nyeem ntawv yog qhov rov qab. Rau ib tug C5 ntsia hlau, backlash yuav tsum<0.01mm. If it increases, the nut preload is lost or the raceway is worn; the nut needs replacement.
4. Ib qho xwm txheej tiag tiag: Kev xaiv cov ntsia hlau tsis raug ua rau tag nrho lub tshuab rov ua haujlwm
Xyoo tas los, lub tuam txhab automation hauv Jiangsu tau tsim lub tshuab gantry dispensing nrog X-axis stroke ntawm 1800mm, yuav tsum tau muab tso rau qhov tseeb ± 0.01mm. Lawv xaiv ib txoj kab uas hla 32 hli, 20 hli txhuas, C5 qib ntsia hlau nrog kev txhawb nqa ruaj khov. Thaum lub sijhawm ua haujlwm, kev vibration loj tshwm sim ntawm kev kub ceev (80m / min), ua rau dispensing txoj hauj lwm drift.
Tom qab kev xam, peb pom cov ntsia hlau qhov ceev ceev yog li ntawm 1700rpm, sib haum mus rau linear ceev ntawm li 85m / min - ze heev rau qhov siab tshaj plaws ceev. Txawm hais tias tsis tshaj tus nqi tseem ceeb, nws twb nyob rau hauv ib cheeb tsam sub-resonance. Meanwhile, parallelism ntawm cov ntsia hlau thiab cov lus qhia kev tsheb nqaj hlau yog 0.06mm / m, ua rau sab nraud quab yuam ntawm cov txiv ntoo.
Kev daws:
- Nce ntsia hlau txoj kab uas hla mus rau 40mm, nce ceev ceev rau 2400rpm.
- Recalibrated parallelism rau 0.015mm / m.
- Hloov kho rau C3 qib ntsia hlau kom raug zoo dua.
Tom qab kev hloov kho, cov cuab yeej ua haujlwm tau zoo thiab qhov tseeb qhov chaw mus txog ± 0.008mm. Cov ntaub ntawv no qhia tau hais tias kev xaiv cov ntsia hlau yuav tsum txiav txim siab tsis yog tsuas yog thauj khoom thiab cov hlau lead, tab sis kuj tseem ceeb ceev ceev, kev teeb tsa raug, thiab qib sib piv.
5. Yuav nug koj tus neeg muag khoom dab tsi thaum yuav lub pob ntsia hlau
- Puas yog cov qhab nia raug lees paub lossis ntsuas qhov tseem ceeb? (Nug ib daim ntawv xeem.)
- Koj puas tuaj yeem muab qhov ua yuam kev nkhaus?
- Puas yog qhov tseem ceeb ceev tau kuaj xyuas? Txoj kev txhawb nqa dab tsi koj pom zoo?
- Koj xav kom qib preload twg?
- Yuav ua li cas peb yuav tsum xyuas backlash tom qab installation?
Cov ntsiab lus
Lub Pob Ntsia Hlau thiab cov kab qhia kev tsheb ciav hlau yog cov koom tes, tsis yog cov khoom ntiag tug. Kev sib raug zoo, ceev ceev, coaxial installation, lubrication txij nkawm - yog tias ib qho ntawm cov no tsis yog lawm, cov cuab yeej yuav "nco lub cim."
Zhejiang Baili Guide Rail tsis yog tsuas yog muaj cov kab qhia kev sib tw nkaus xwb tab sis kuj tseem muaj cov pob ntsia hlau siab, los ntawm qib C7 txog C3. Peb tuaj yeem muab cov kev xaiv ua tiav cov ntsia hlau-plus-rail xaiv, kom ntseeg tau tias muaj qhov sib xws thiab kev teeb tsa tsis muaj teeb meem. Txais tos hu rau peb kom muab tswv yim.
Xaiv cov neeg koom tes kom raug, thiab koj cov cuab yeej yuav khiav kom raug thiab tsis tu ncua.
