Yuav ua li cas kho qhov precision ntawm lub tshuab dhos ntsug?

I. Kev Npaj thiab Cov Ntsiab Cai Ua ntej Kev Kho Kom Zoo

1. Ib puag ncig thiab xwm txheej: Lub tshuab cuab yeej yuav tsum tau preheated thiab khiav rau ib lub sijhawm kom paub meej tias kev hloov kho tau ua nyob rau hauv lub xeev ruaj khov.

2. Kev hloov kho ib ntus: Ua raws li lub hauv paus ntsiab lus ntawm "tag nrho ua ntej hauv zos" thiab "zoo li qub ua ntej dynamic" kom tsis txhob rov kho dua.

3. Kev npaj cov cuab yeej: Cov cuab yeej siv feem ntau suav nrog laser interferometer, siab - qib precision, dial indicator, straightedge, thiab spindle gauge bar.

II. Lub ntsiab hloov khoom siv thiab cov txheej txheem

1. Tshuab cuab yeej Leveling Kho:

Lub hom phiaj: txhawm rau xyuas kom meej tias qhov chaw ua haujlwm saum npoo yog perpendicular rau spindle rotation axis, tshem tawm machining yuam kev los ntawm tilting.

Txoj kev: Siv cov qib precision los kho cov thauj tog rau nkoj bolts, tswj tag nrho cov theem ntawm lub tshuab cuab yeej nyob rau hauv qhov yuav tsum tau muaj (piv txwv li, 2 division / 1000mm).

2. Worktable Flatness Kho:

Lub hom phiaj: Los xyuas kom meej qhov flatness ntawm workpiece mounting siv.

Txoj kev: Tswj qhov kev ua yuam kev flatness los ntawm kev sib tsoo los yog sib tsoo ntawm qhov chaw ua haujlwm, thiab siv lub ntsuas qhov ncaj thiab dial rau kev tshuaj xyuas.

3. Spindle Accuracy Adjustment:

Radial Runout: Txo cov kabmob -cov ntaub ntawv tshem tawm los ntawm kev xaiv cov kabmob uas tsim nyog, kev sib koom ua ke, thiab preloading.

Axial Movement: Kho qhov axial clearance ntawm cov bearings thiab siv tus ntoo khaub lig-zoo li tus qauv ntxhua khaub ncaws kom tshem tawm qhov yuam kev perpendicularity ntawm cov txiv ntoo kho.

Cov Lus Qhia Tseem Ceeb: Spindle radial runout thiab axial txav yuav tsum feem ntau tswj tsis pub dhau 0.01mm.

4. Coordinate Axis Motion Accuracy Adjustment:

Guide Rail Straightness thiab Parallelism: Kho cov kev taw qhia rails siv cov txheej txheem sib tsoo thiab sib tsoo, thiab xyuas nrog lub ntsuas ncaj nraim thiab dial taw qhia kom tswj tau qhov ncaj ntawm cov lus qhia hauv kab rov tav thiab ntsug.

Guide Rail Perpendicularity: Kho qhov kev sib nrig sib perpendicularity ntawm ob qho tib si axis qhia rails, thiab xyuas nrog ib tug square thiab dial qhia.

Kev Pom Zoo thiab Kev Rov Ua Dua: Tshawb xyuas siv lub laser interferometer, thiab kho servo tsis thiab tshem tawm ntawm cov hlau lead thiab txiv ntseej khub kom paub tseeb tias qhov tseeb.

5. Crossbeam Movement Accuracy Adjustment (rau ob -kem hom):

Lub hom phiaj: txhawm rau xyuas kom muaj kev sib luag ntawm cov kab hla mus rau lub rooj ua haujlwm thiab kev sib koom ua ke ntawm ob kab thaum lub sijhawm txav mus los.

Txoj kev: Kho qhov sib npaug ntawm cov kab lus qhia hla hla, tswj tus nqi qaij thaum lub sij hawm hla kev txav, thiab xyuas kom meej cov kab rov tav raug ntawm ob kab.

III. Kev txheeb xyuas thiab ceev faj tom qab hloov kho

1. Kev Tshawb Fawb thiab Kev Tshawb Fawb: Tom qab kev hloov kho, qhov tseeb ntawm cov duab kos duab zoo dua - yuav tsum tau ua raws li cov qauv (xws li GB/T 17421).

2. Ceev faj:

Systematicity: Geometric raug cov khoom muaj kev cuam tshuam thiab yuav tsum tau hloov kho kom tsis txhob rov ua dua.

Kev tuav pov hwm qhov tseeb: Kev tshuaj xyuas tsis tu ncua yuav tsum tau ua tom qab hloov kho, xav txog qhov cuam tshuam ntawm yam xws li kev daws teeb meem hauv paus.

Kev Nyab Xeeb Ua Ntej: Cov txheej txheem hloov kho yuav tsum ua raws li cov txheej txheem kev nyab xeeb ua haujlwm kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv.

IV. Qhov sib txawv ntawm Kev Kho Kom Zoo Thiab Kev Tshawb Fawb

1. Kev tshuaj xyuas: Qhov no suav nrog kev siv cov cuab yeej los ntsuas qhov tseeb ntawm lub tshuab cuab yeej los txiav txim seb nws puas ua tau raws li cov qauv.

2. Kev hloov kho: Qhov no yog cov txheej txheem ntawm kev kho cov cuab yeej siv lub tshuab kom raug rau qhov kev tso cai los ntawm kev kho tshuab, kev hloov pauv, thiab lwm yam txhais tau tias tom qab kuaj pom muaj teeb meem.
