Amantongomane ayizibophelelo ezibalulekileyo ekudibaneni koomatshini, kwaye umgangatho wabo uchaphazela ngokuthe ngqo ukhuseleko kunye nokuthembeka kwezixhobo. Ukuqinisekisa ukuba amandongomane ayahlangabezana nemigangatho esebenzayo, kufuneka enze inkqubo yokuhlolwa okungqongqo. Eli nqaku lichaza inkqubo epheleleyo yokuhlola i-nut, ukusuka kwizinto eziluhlaza ukuya kwimveliso egqityiweyo.
1. Ukuhlolwa kwembonakalo
Ukuhlolwa kwembonakalo yinyathelo lokuqala lokuhlola i-nut, ngokuyinhloko ukuvavanya umphezulu weziphene. Uhlolo lubandakanya:
Iintanda, imikrwelo, kunye neeBurrs: Jonga umphezulu wendongomane ngokubonakalayo okanye ngeglasi yokukhulisa ukuqinisekisa ukuba igudile kwaye ayinazo iintanda okanye amanqaku omatshini.
Umsonto Ingqibelelo: Jonga umsonto ukuba uphelele na, amazinyo angekhoyo, amazinyo abolileyo, okanye imisonto engalungelelani kakuhle.
I-Dimensional Consistency: Hlola kuqala i-nut ukuqinisekisa ukuba i-hexagon (okanye enye imilo) ifana kwaye ayinakho ukuguqulwa okubalulekileyo.
2. Umlinganiselo woMda
Ukuchaneka komda wamandongomane kukuchaphazela ngokuthe ngqo ukulingana kwawo neebholiti, ngoko ke izixhobo ezikhethekileyo zokulinganisa ziyafuneka ukuze zihlolwe:
Idayamitha yangaphandle, i-Inner Diameter, kunye nokutyeba: Sebenzisa i-caliper okanye i-micrometer ukulinganisa i-diameter yangaphandle ye-nut, i-diameter yentambo yangaphakathi, kunye nobukhulu bayo bonke ukuqinisekisa ukuthotyelwa kwemigangatho (efana ne-ISO, i-DIN, kunye ne-GB).
Iiparamitha zomsonto: Sebenzisa igeyiji yomsonto (hamba/hayi{0}}hamba igeyiji) ukujonga ukuba iprofayile yomsonto, inowuthi, kunye nedayamitha iyahlangabezana neemfuno.
IHexagonal/Square Across-Imilinganiso eFlethi: Ngamandongomane anehexagonal, thelekisa umgama ukunqumla iiflethi ukuqinisekisa ukuhambelana nesikrufu.
3. Ukuhlolwa kwemisonto
Umsonto ngundoqo we nut, okwenza ukuba ukuhlolwa kwayo kubaluleke kakhulu:
Hamba/Hayi{0}Hamba kuVavanyo lweGauge: Sebenzisa i-go (hamba) kwaye ungayeki{1}}uyigeji ukuze uhlole umsonto wokuthotyelwa. I-go gauge kufuneka ikwazi ukujija ngokutyibilikayo, ngelixa i-no{3}}go gauge kufuneka isebenze ngokupheleleyo.
Ukuhlolwa kweProfayili yomsonto: Sebenzisa iprofayili yomsonto ukulinganisa iiparamitha ezifana ne-angle yeprofayili yomsonto kunye nokutenxa kwepitch. Oku kulungele{1}}iimfuno ezichanekileyo eziphezulu.
Uvavanyo loBulukhuni bemisonto: Kwezinye iimeko, ubulukhuni bendawo enemisonto kufuneka buvavanywe ukuze kuqinisekiswe ukuxhathisa kokunxiba kunye namandla.
4. Uvavanyo loBulukhuni
Ukuqina kwentongomane kuchaphazela amandla ayo okuqina kunye nokumelana nokudinwa. Ezi ndlela zilandelayo zisetyenziswa ngokuqhelekileyo:
I-Rockwell Hardness Tester (HRB / HRC): Isebenza kwi-carbon steel kunye ne-alloy steel nuts ukulinganisa ubunzima bomhlaba.
I-Brinell Hardness Tester (HB): Ifanelekile kwizinto ezithambileyo (ezifana nobhedu kunye ne-aluminium nuts), ukuvavanya ukusabalalisa kobunzima ngokubanzi.
Vickers Hardness Tester (HV): Ilungele amandongomane amancinci okanye abhityileyo -abiyelwe ngodonga, inikezela ngedatha echanekileyo yobulukhuni bendawo.
5. Uvavanyo lwePropati yoomatshini
Iimpawu zomatshini zamandongomane zichaphazela ngokuthe ngqo umthamo wabo- wokuthwala. Iimvavanyo eziqhelekileyo ziquka:
Uvavanyo lwamandla okuqina: Ukuvavanya owona mthwalo uphezulu-umthamo wokuthwala we nut phantsi komthwalo usebenzisa umatshini wokuvavanya i-tensile.
Uvavanyo lomthwalo wobungqina: Ukusebenzisa umthwalo othile ngokwemigangatho (efana ne-ISO 898) ukuvavanya ukuguqulwa kweplastiki kwi-nut.
Uvavanyo lweTorque: Ukulinganisa i-torque esetyenzisiweyo ngexesha lokuqinisa kunye nokukhulula i-nut ukuqinisekisa ukuba ihlangabezana neemfuno zendibano.
6. UVavanyo loNyango loMphezulu (Ukuba Luyasebenza)
Ukuba i-nut iphathwe ngonyango olungaphezulu olufana ne-zinc plating, i-nickel plating, okanye i-phosphating, uvavanyo olongezelelweyo luyafuneka:
Ukutyeba kokutyabeka: Usebenzisa igeyiji yobukhulu bokwaleka, qinisekisa ukuba i-coating iyahlangabezana neemfuno (umzekelo, i-zinc plating idla ngokuba Khulu okanye ilingana ne-5μm).
UVavanyo loKumelana nokuMhlwa: Uthintelo lomhlwa luvavanywa ngovavanyo lwesitshizi setyuwa (umzekelo, i-5% yesisombululo seNaCl, iiyure ezingama-48-96).
Uvavanyo lwe-Adhesion: Ihlola i-coating for adhesion kwaye inqande i-detachment.
7. Uvavanyo olungonakaliyo (ukuba luyafuneka)
Kumandongomane aneemfuno eziphezulu zokhuseleko (ezinje nge-aerospace ebalulekileyo kunye nezixhobo zemoto), oku kulandelayo kunokufuneka:
Uvavanyo lweMagnetic Particle (MT): Ibona umphezulu okanye kufutshane{0}}neentanda zobuso.
Uvavanyo lwe-Ultrasonic (UT): Ifumanisa iziphene zangaphakathi ezifana ne-shrinkage cavities kunye nokufakwa.
X - Uvavanyo lweRay (RT): Ifanelekile ukuhlalutya isakhiwo sangaphakathi samantongomane achanekileyo.
8. Ukuhlolwa kokuGqibela kunye nokuPakisha
Emva kokuba zonke iimvavanyo zigqityiwe, amantongomane afanelekileyo afumana oku kulandelayo:
Ukuhlolwa kwakhona kwesampulu{0}}: Iisampulu engaqhelekanga ngebhetshi ukuqinisekisa ukungaguquguquki.
Ukumakisha nokulandelelwa: Ukuleyibhelishwa ngolwazi olufana nokuchazwa, ibhetshi, kunye nomhla wovavanyo kunceda ukulandeleka komgangatho.
UThintelo lomhlwa kunye nokuPakisha: Unyango lothintelo lomhlwa (umzekelo, ukuthambisa) lwenziwa njengoko kufuneka, kwaye ukufuma{2}} kunye nokupakishwa komothuko{3}}kusetyenziswa.
Ukuqukumbela
Inkqubo yokuhlola i-nut ihlanganisa iinkalo ezininzi, kubandakanywa ukubonakala, imilinganiselo, imicu, ukuqina, kunye neempawu zomatshini, ukuqinisekisa ukhuseleko kunye nokuthembeka kwizicelo eziphathekayo. Iimfuno zamandongomane zinokwahluka kumashishini ahlukeneyo (njengokwakha, iimoto, kunye nokubhabha), kodwa imigangatho yokuhlola engqongqo ihlala ingundoqo ekuqinisekiseni umgangatho.
