Yog tias ob txoj hlua tsis sib luag, lub slider yuav muaj kev ntxhov siab rau sab nraud thaum lub sijhawm txav.

Yuav ntsuas li cas:

Tom qab straightening lub reference rail, mount lub dial taw qhia ntawm nws slider, nrog rau lub taub hau hu rau sab ntawm lub thib ob rail. Nias lub slider mus thiab nco ntsoov qhov kev hloov pauv ntawm rab koob -qhov no yog qhov yuam kev ntawm qhov sib npaug ntawm ob txoj hlua.

Cov qauv siv:

• Standard qib: Tsawg dua los yog sib npaug rau 0.02mm / m

• Qib Precision: Tsawg dua lossis sib npaug ntawm 0.01mm / m

2.3 Slider Qhov siab sib txawv

Yog tias ntau lub sliders ntawm tib lub tsheb ciav hlau muaj qhov siab tsis sib haum, lub rooj ua haujlwm yuav tig.

Yuav ntsuas li cas:

Muab cov straightedge hla ntau sliders. Siv qhov ntsuas ntsuas ntsuas qhov siab ntawm qhov ncaj ntawm txhua txoj haujlwm slider. Qhov sib txawv ntawm qhov kev nyeem ntawv siab tshaj thiab qis tshaj yog qhov siab sib txawv.

Daim ntawv pov thawj: Tsawg dua lossis sib npaug li 0.01mm

3. Dynamic Accuracy: Teeb meem ntog thaum nws txav mus

Txawm hais tias cov ntaub ntawv zoo li qub zoo li qub, nws txhais tau tias tsis muaj dab tsi yog tias lub kaw lus tsis ua haujlwm zoo.

3.1 Khiav Resistance

Fluctuating kuj qhia tau hais tias kev tsheb ciav hlau distortion los yog teeb meem sab hauv nrog lub slider.

Yuav ntsuas li cas:

Thawb lub slider los ntawm txhais tes kom hnov ​​​​yog tias muaj kev tiv thaiv zoo ib yam thoob plaws hauv cov hlab ntsha. Yog tias koj muaj lub laub- rub lub ntsuas, ntsuas lub zog xav tau thiab xyuas qhov sib txawv ntawm qhov siab tshaj plaws thiab nruab nrab quab yuam.

Txoj cai ntawm Thumb:

• Resistance fluctuation >15% lav kev tshawb nrhiav

• Rau cov cuab yeej precision, tsom rau Tsawg dua lossis sib npaug li 10%

• Pom tseeb "cov ntsiab lus nplaum"=tam sim ntawd poob

3.2 Ua haujlwm nrov nrov

Suab nrov yog qhov qhia tau zoo tshaj plaws ntawm kev tsheb nqaj hlau. Ib txwm ua haujlwm suab zoo li ib qho rustle; teeb meem tshwm sim li nias, sib tsoo, lossis squealing.

Yuav ntsuas li cas:

Mloog ntawm kev khiav hauj lwm ceev. Lub stethoscope yuav pab tau, tab sis ib tug ntsia hlau ntev nias rau koj pob ntseg kuj tuaj yeem ua rau koj nkag siab zoo txog dab tsi tshwm sim.

Dab tsi Yog Txais:

• Tsis muaj sij hawm "nias" suab

• Tsis muaj suab nrov sib txhuam

• Lub suab nrov feem ntau Tsawg dua lossis sib npaug li 70dB

3.3 Kub nce

Yog hais tias lub tsheb ciav hlau kub dhau, txawm tias lub preload yog siab dhau los yog lubrication tsis txaus.

Yuav ntsuas li cas:

Khiav cov cuab yeej siv ntau tshaj 30 feeb tsis tu ncua. Ntsuas qhov kub ntawm qhov chaw tsheb ciav hlau nrog lub ntsuas kub infrared, tom qab ntawd rho tawm qhov kub thiab txias kom tau txais qhov kub nce.

Kev siv tus nqi:

• Pob ntawv qhia rails: Tsawg dua lossis sib npaug li 25 degree

• Roller guide rails: Tsawg dua lossis sib npaug li 35 degree

• Qhov kub ntawm qhov sib txawv ntawm tib lub tsheb ciav hlau yuav tsum tsis txhob siab tshaj 5 degree

4. Qhov tseeb qhov tseeb: Qhov kawg xa tuaj

Thaum kawg ntawm hnub, yam uas cov neeg siv khoom txhawj xeeb tsis yog qhov ncaj nraim ntawm koj txoj kev tsheb ciav hlau - nws puas yog cov khoom siv ua haujlwm raug. Tsis txhob hla cov kauj ruam no.

Yuav ntsuas li cas:

Siv lub laser interferometer los yog grating scale. Teem cov ntsiab lus ntsuas (piv txwv li, txhua 100mm). Txav los ntawm xoom mus rau qhov kev taw qhia zoo, sau qhov tseeb ntawm txhua qhov taw tes, tom qab ntawd rov qab rov qab. Kev ntsuas qhov tseeb qhov tseeb thiab rov ua qhov tseeb qhov tseeb qhia qhov tseeb ntawm cov khoom siv.

Hom qauv:

• Cov cuab yeej siv hluav taws xob dav dav: qhov chaw tsawg dua lossis sib npaug ntawm 0.05mm, rov ua dua Tsawg dua lossis sib npaug rau 0.03mm

• Precision machining khoom: positioning Tsawg dua los yog sib npaug rau 0.01mm, rov ua dua Less dua los yog sib npaug rau 0.005mm

• Ultra- cov khoom siv precision: qhov chaw tsawg dua lossis sib npaug ntawm 0.003mm, rov ua dua Less dua lossis sib npaug rau 0.002mm

5. Daim Ntawv Qhia Txais: Muab tso rau hauv kev sau ntawv

Tsis txhob cia siab rau lub cim xeeb -cov ntaub ntawv txhua yam. Nws yuav cawm koj mob taub hau tom qab thaum taug qab cov teeb meem.

6. Ib qho xwm txheej tiag tiag: Cov teeb meem pom thaum txais

Nyuam qhuav pib lub xyoo no, ib lub tuam txhab automation hauv Zhejiang nyuam qhuav sib sau ua ke cov khoom siv gantry tshiab thiab tab tom npaj rau kev txais. Kuv tau mus pab nrog kev tshuaj xyuas thiab pom ob peb yam teeb meem:

• Reference rail ncaj: 0.03mm / m-yuav tsum tau yog 0.01

• Dual -rail parallelism: 0.05mm/m-ze li tsib npaug ntawm qhov txwv

• Kev tuav tuav tau qhia pom tseeb "jerky" tsis kam nyob nruab nrab ntawm cov hlab ntsha tawg

Tom qab qee qhov kev khawb, peb pom cov chaw siab ntawm lub hauv paus mounting. Cov bolts tau nruj ntawm ib kawg mus rau lwm qhov, twisting cov ntsia hlau. Txoj kev tsheb ciav hlau thib ob tsis ua raws li kev siv tsheb ciav hlau - ob qho tib si tau mus rau lawv tus kheej txoj kev.

Peb rescraped lub hauv paus, rov kho cov bolts los ntawm qhov chaw sab nraud, thiab rov kho qhov sib npaug. Cov txiaj ntsig rov qab: ncaj 0.008mm / m, parallelism 0.009mm / m, thiab kev hloov pauv tsis kam poob ntawm 25% mus rau 8%. Cov cuab yeej siv tau dhau qhov kev lees paub thiab tau ua haujlwm zoo txij li ntawd los.

Kev xav zaum kawg

Tsis txhob cia siab rau kev xav lossis "kaw txaus" thaum txiav txim siab rail installation zoo. Ib txoj kev tshuaj xyuas yooj yim yuav siv sij hawm me ntsis tab sis tuaj yeem ntes teeb meem ua ntej lawv mus txog tus neeg siv khoom. Yog tias muaj ib yam dab tsi tsis ncaj ncees lawm tom qab cov cuab yeej tsim khoom, tus nqi poob qis thiab kev kho kom deb dua qhov kev siv zog me me tau txais kev cawmdim thaum lub sijhawm teeb tsa.
