I. Basic Visual Inspection
1. Kev sib tw: Lub ntsej muag kawg ntawm lub ntsej muag yuav tsum tau yaug nrog lub workpiece nto, tsis muaj tilting lossis qhov khoob, thiab 2-3 threads yuav tsum raug nthuav tawm.
2. Xov Xwm Txheej: Cov xov yuav tsum tsis muaj stripped, misaligned, los yog chipped hniav. Cov txiv ntseej yuav tsum tig mus zoo yam tsis muaj kev cuam tshuam los yog qhov txawv txav.
3. Cov Txheej Txheem Nto: Lub taub hau hexagonal ntawm cov txiv ntseej yuav tsum tsis txhob muaj cov cim ntawm kev sib tw, tawg, lossis deformation ntawm cov ciaj ntswj. Qhov saum npoo tiv thaiv -corrosion txheej yuav tsum tsis txhob raug puas tsuaj.
II. Torque thiab Force Verification
1. Torque Verification: Re- tshuaj xyuas siv lub calibrated torque wrench. Qhov sib txawv ntawm ± 10% los ntawm kev tsim torque yog suav tias tsim nyog.
2. Tapping Test: Maj mam kov lub ntug ntawm cov txiv ntoo nrog 0.3-0.5 kg rauj. Nrog koj tus ntiv tes ze ntawm lub tshuab ntxhua khaub ncaws, me ntsis, txawm tias kev vibration yog hnov. Kev co ntau dhau qhia tau hais tias nyob rau hauv - zawm, thaum tsis muaj kev vibration qhia tias nruj dhau.
III. Tshwj xeeb Scenario Verification
1. High-Ntshav muaj zog: Kos cov haujlwm sib xws ntawm cov txiv ntoo thiab cov ntsia hlau. Loosen lub txiv ntoo los ntawm 60℃thiab rov qab kom txog thaum cov cim sib dhos. Yog hais tias lub torque sib txawv nyob rau hauv qhov kev tso cai, nws yog suav hais tias tsim nyog.
2. Vibration Condition Nuts: Ua qhov simulated vibration test tom qab kev teeb tsa. Yog hais tias lub txiv ntseej tsis xoob ntawm nws tus kheej thiab cov kev tiv thaiv -loosing qauv (nylon nplhaib, xauv lub tshuab ntxhua khaub ncaws) yog tag nrho ntawm qhov chaw, nws yog qhov tsim nyog.
3. Welded Hexagonal Nuts: Yog tias cov khoom siv welded tsis muaj qhov porosity thiab tsis tiav welds, thiab cov txiv ntoo tsis deform tom qab txias, thiab cov xov tseem tuaj yeem ua tau zoo, nws yog qhov tsim nyog.
IV. Kev Tshawb Fawb Ua Haujlwm Kawg
Yog tias cov khoom sib txuas tsis muaj qhov sib txawv txav los yog xoob, tag nrho cov qauv sib npaug sib npaug, thiab cov khoom thauj -cov kabmob thiab kev sib khi yuav tsum tau ua raws li kev ua haujlwm, kev teeb tsa raug suav tias yog tag nrho.
