Vertical Lathe Fault Diagnosis Process

I. Fault Information Collection and Preliminary Jugment

1. Nug nrog cov neeg ua haujlwm
Nkag siab txog cov xwm txheej tshwj xeeb thaum qhov txhaum tshwm sim (piv txwv li, lub suab nrov txawv txav, lub tswb cim, machining yuam kev), lub sij hawm ntawm qhov tshwm sim (pib- nce, hnyav load, tom qab ua haujlwm ntev), thiab seb puas muaj kev hloov pauv ua haujlwm.

2. Saib xyuas cov ntaub ntawv tswb
Tshawb xyuas cov ntaub ntawv keeb kwm ntawm lub tswb ntawm CNC system, sau cov xov tooj tswb thiab lub sijhawm, thiab ua qhov kev txiav txim ua ntej ntawm hom txhaum (xws li, servo, spindle, PLC, thiab lwm yam).

3. Khaws rau ntawm -Site Condition
Tsis txhob rov pib dua lossis rov pib dua ua ntej qhov laj thawj raug txheeb xyuas kom tsis txhob muaj kev puas tsuaj rau qhov txhaum.

II. Visual Inspection Method (Sensory Inspection)
Ua cov tshev hauv qab no nrog lub hwj chim tawm:

1. Kev tshuaj xyuas qhov muag
Xyuas txhua lub txee tswj hluav taws xob rau cov tshuab hluav taws xob, cov khoom siv hluav taws xob, lossis cov khoom siv hluav taws xob;
Saib xyuas cov roj hydraulic thiab seb lub lubrication system puas muab roj ib txwm;
Tshawb xyuas cov cuab yeej ncej, qhia cov ntsia hlau, chuck, thiab lwm yam khoom siv tshuab kom pom tseeb xoob, hnav, lossis cuam tshuam los ntawm cov khoom txawv teb chaws.

2. Kov tshuaj xyuas
Xyuas seb lub cev muaj zog, spindle, thiab bearing vaj tse puas overheating;
Paub meej tias lub rooj tsav xwm hauv Circuit Court yog ruaj khov thiab kev sib txuas ntawm lub ntsaws ruaj ruaj.

3. Fais fab- ntawm Kev Xeem Khiav (Ua haujlwm nrog ceev faj)
Cia lub hwj chim rau thiab saib xyuas cov pa luam yeeb, sparking, los yog cov ntxhiab tsw txawv txav, thiab mloog lub suab ua haujlwm kom ntseeg tau tias nws zoo li qub.

III. Teeb liab thiab tswb tsom xam

1. Hardware Alarm Indicators
Txheeb xyuas cov teeb pom kev zoo thiab teeb pom kev txhaum ntawm CNC system, tsav tsheb, thiab PLC modules, thiab txhais lawv lub ntsiab lus raws li phau ntawv qhia.

2. Software Alarm Diagnosis
Raws li cov xov tooj ceeb toom uas tshwm rau ntawm lub vijtsam, sab laj nrog lub tshuab cuab yeej phau ntawv kuaj mob kom tau txais qhov ua tau ua txhaum cai thiab cov lus qhia daws teeb meem.

3. Interface Signal Check
Siv PLC programmer los khaws cov teeb liab sib cuam tshuam ntawm CNC thiab PLC, thiab paub meej tias cov kev tswj hwm tau xa mus li cas, tshwj xeeb tshaj yog siv rau "tsis muaj kev ua" yam tsis raug.

IV. Hauv -Kev daws teeb meem Subsystem tob

1. Spindle System Fault Diagnosis

Spindle tsis tig: Tshawb xyuas lub zog theem ib ntus, qhov tsis muaj inverter, txoj siv tawv nruj, thiab seb cov lus qhia S / M hauv qhov kev pab cuam puas yog.

Spindle suab nrov lossis txo qhov tseeb: Txheeb xyuas cov kabmob radial runout (dhau 0.02mm), thiab tshuaj xyuas iav meshing thiab txhaj tshuaj hydrostatic roj.

2. Pub thiab Tool Post System Diagnosis:

Cov cuab yeej khiav Creep los yog qhov chaw tsis raug: Txheeb xyuas cov lus qhia kev tsheb ciav hlau lubrication, rov qab them tus nqi, cov ntsia hlau ua ntej, thiab cov npoo nruj.

Tuam Txhab Tsis Tig: Tshawb xyuas cov cuab yeej txoj haujlwm teeb liab kab txuas ntxiv, teeb liab disk magnet demagnetization, thiab Hall lub caij puas.

3. Hydraulic thiab Lubrication System Diagnosis:

Roj Pump Tsis Siv Neeg Shutdown: Txheeb xyuas qhov chaw thermal relay, roj twj tso kua mis ntau dhau, lossis kev sib tsoo tshuab.

Roj Leakage los yog Tsis Txaus Siab: Tshawb nrhiav kev laus cov ntsaws ruaj ruaj, xoob screws, thiab roj Circuit Court thaiv.

4. Kev Ntsuas Hluav Taws Xob Hluav Taws Xob:

System Crash lossis Parameter Poob: Clear nco thiab rov- nkag tsis tau; kos rau +24V fais fab mov luv luv.

Emergency Stop lossis Overtravel Tswb: Pib dua lub khawm nres thaum muaj xwm txheej ceev thiab rov qab lub axis kom tawm ntawm thaj chaw txwv.

V. Kev ntsuas ntsuas thiab ntsuas ntsuas ntsuas

1. Kev ntsuas siv lub tshuab multimeter thiab oscilloscope: Kev ntsuas lub zog hluav taws xob voltage, theem teeb liab, lub cev muaj zog winding tsis kam, thiab lwm yam, txhawm rau txiav txim siab seb puas muaj cov kab hluav taws xob qhib, luv Circuit Court, lossis teeb liab anomalies.

2. Parameter Comparison Method: Sib piv cov txheej txheem tam sim no nrog cov thawj cov ntaub ntawv thaub qab los xyuas cov khoom hloov pauv tsis raug, tshwj xeeb tshaj yog cov tsis muaj analog.

3. Kev Ntsuas Laser Interferometer: Siv rau siab - ntsuas qhov tseeb ntawm qhov tsis raug ntawm cov duab kos xws li cov hlau lead ntsia hlau backlash thiab qhia kev ncaj nraim.

VI. Fault Confirmation thiab tuav

1. Ib qho txhaum: ncaj qha kho lossis hloov cov khoom puas.

2. Cov Faults tsis yooj yim: Kov lawv cov khoom los ntawm cov khoom raws li qhov tseem ceeb kom tsis txhob muaj qhov tsis raug.

3. Nrhiav tsis tau: Siv txoj kev hloov khoom seem lossis hla- txoj kev hloov pauv kom txo qis qhov txhaum (xws li, hloov nrog tib lub qauv Circuit Court board rau kev sim).
