Yuav ua li cas kho qhov Preload ntawm Kub Khiav Sensor

Qhov zais cia kom teeb tsa qhov kub khiav sensor lub preload yog ua ntej tsim lub hom phiaj tus qauv, tom qab ntawd ua kom raug kho raws li theem machining / kev sib dhos. Qhov no thaum kawg yuav khaws cov preload nyob rau hauv qhov kev tso cai ntau yam rau cov qauv uas muaj feem xyuam. Cov hauv qab no yog cov kauj ruam meej:

 

1. Qhia meej txog cov qauv sib thooj lub hom phiaj Preload Standard

Txhawm rau tiv thaiv qhov muag tsis pom kev ua haujlwm, txheeb xyuas lub hom phiaj raws li cov qauv kev teeb tsa ua ntej hloov kho. Tus qauv feem ntau yog:

Structure thiab Scenario ntawm Installation

Preload Range ntawm Lub Hom Phiaj

Feem ntau siv hom clamping yog threaded.

0.15-0.25 hli

Screw Fixed Type Set

0.1-0.2 hli

Loj Txhaj Mould nrog Siab Siab

0.2-0.3 hli

 

2. Kev Hloov Kho Thaum Machining (Ua ntej qhov kawg qhov tob Machining)

Lub machining qhov ntev ncaj qha cuam tshuam rau preload, thiab theem no muab qhov tseeb tshaj plaws hloov kho:

Ua ntej, txiav txim siab qhov tseeb sensor qhov kev sojntsuam protrusion ntev, lossis qhov kev ncua deb ntawm lub ntsej muag kawg ntawm lub ntsej muag thiab lub ntsej muag mounting xov kawg;

Txiav txim siab lub hom phiaj qhov tob uas siv cov qauv hauv qab no: Mounting Qhov Qhov tob=Probe Protrusion Length - Target preload; tuav tswj nruj ntawm qhov tob qhov siab nyob rau hauv ± 0.05mm thoob plaws hauv milling. Ntsuas lub qhov tob dua tom qab txiav. Yog hais tias lub qhov tob tob heev (preload me me), ntxiv ib qho stainless hlau shim ntawm lub thickness kom zoo rau qhov kev sojntsuam tus Tsov tus tw los ntxiv cov preload; Yog tias lub qhov tob tob dhau lawm (preload loj dhau), zom lub qhov hauv qab mus rau lub hom phiaj qhov tob.

 

3. Kev hloov kho tom qab sib dhos lossis machining Thaum lub preload tuaj yeem hloov pauv thaum tsim kho, lub qhov tob yog tsau:

(1) Kev hloov kho rau ntau dhau preload (ntau tshaj lub hom phiaj siab tshaj plaws):

Tshem lub sensor sib nrug. Sib tsoo lub qhov hauv qab kom coj cov preload mus rau qhov xav tau ntau yam yog tias qhov kev tso cai machining tawm mus yog qhov ua rau.

Yog hais tias overtightening tshwm sim thaum lub sij hawm sib dhos, reassemble thiab ua tib zoo tswj lub℃ntawm zawm:

Siv lub torque wrench, kho lub torque raws li cov xov specifications (M3 yog 0.3 ~ 0.6 N·m, M4 yog 0.5 ~ 1.0 N·m). Thaum qhov xav tau torque tau txais, nres nruj.

Tsis muaj lub torque wrench: Tom qab zawm mus rau txoj hauj lwm kom zoo, tsuas yog ntxiv 1/12 ~ 1/6 tig rau threaded clamping hom thiab ib qho ntxiv 1/8 ~ 1/4 tig rau hom ntsia hlau.

Txhawm rau txo qis preload mus rau qhov kev lees paub, loosen cov ntsia hlau los ntawm 1/8 tig. (2) Kev hloov kho rau qhov tsis txaus ua ntej- nruj (hauv qab Lub Hom Phiaj Tsawg)

Tighten tus naj npawb tsim nyog ntawm kev tig raws li tus qauv tom qab ua kom tsis muaj cov khib nyiab nyob hauv qab ntawm lub qhov.

If, even after tightening to the limit, the desired pre-tightening quantity is still not reached: To augment the pre-tightening amount, remove the sensor and put a 0.1–0.2 mm thick stainless steel shim to the probe tail.

 

4. Kev Tshawb Fawb Txog Kev Tsim Nyog thiab Kev Pom Zoo yog qhov tsim nyog kom paub tseeb tias qhov ua ntej - nruj kom muaj nuj nqis txaus siab rau cov qauv tom qab hloov kho:

Kev Tshawb Fawb Ua Ntej: Siv digital thawb- rub lub zog gage los ntsuas qhov sib tiv tauj peb zaug, tom qab ntawd qhov nruab nrab cov txiaj ntsig. Lub zog sib piv uas poob ntawm 5 thiab 15 N yog suav tias tsim nyog.

Ceev rau ntawm-Kev Tshawb Fawb qhov chaw: Tshawb xyuas qhov ua tau zoo ntawm qhov ntsuas kub. Lub pre- kev hloov kho tus nqi nruj yog qhov tseeb yog tias qhov ntsuas kub ruaj khov hloov pauv tsawg dua lossis sib npaug li ± 3℃thiab qhov sib txawv ntawm qhov kub khiav cua sov tus nqi thiab qhov tsim nyog sensor ntawm tib lub ntsiab lus yog tsawg dua 30%.
