Linate ke li-fasteners tsa bohlokoa likhokahanong tsa mochini, 'me boleng ba tsona bo ama ka kotloloho polokeho le ts'epahalo ea lisebelisoa. Ho etsa bonnete ba hore linate li finyella litekanyetso tse sebetsang, li tlameha ho etsoa tlhahlobo e matla. Sengoliloeng sena se qaqisa ts'ebetso e felletseng ea tlhahlobo ea linate, ho tloha ho thepa e tala ho isa sehlahisoa se felileng.
1. Tlhahlobo ea Ponahalo
Tlhahlobo ea ponahalo ke mohato oa pele oa tlhahlobo ea linate, haholo-holo ho hlahloba bokaholimo bakeng sa liphoso. Tlhahlobo e kenyelletsa:
Cracks, Scratches, and Burrs: Sheba bokaholimo ba linate ka pono kapa ka khalase e holisang ho netefatsa hore bo boreleli ebile ha bo na mapetso kapa matšoao a mochini.
Botšepehi ba Khoele: Hlahloba khoele hore na e feletse, meno a sieo, meno a bolileng, kapa likhoele tse sa lumellaneng hantle.
Dimensional Consistency: Qalong hlahloba nate ho netefatsa hore hexagon (kapa sebopeho se seng) e ts'oana ebile ha e na phetoho e kholo.
2. Tekanyo ea tekanyo
Ho nepahala ha linate ho ama ka kotloloho ho lekana ha tsona ka liboutu, ka hona ho hlokahala lisebelisoa tse khethehileng tsa ho lekanya bakeng sa tlhahlobo:
Outer Diameter, Inner Diameter, le Botenya: Sebelisa caliper kapa micrometer ho lekanya bophara ba nate e ka ntle, bophara ba khoele e ka hare, le botenya ba kakaretso ho netefatsa ho lateloa ha maemo (joalo ka ISO, DIN, le GB).
Mekhahlelo ea Khoele: Sebelisa sekala sa khoele (go/no{0}}go gauge) ho lekola hore na profaele ea khoele, molumo, le bophara ba tsona li fihlela litlhoko.
Hexagonal/Square Across-Flat Dimensions: Bakeng sa linate tse hexagonal, lekanya sebaka sa ho haola le lifolete ho netefatsa hore li tsamaellana le wrench.
3. Tlhahlobo ea Khoele
Khoele ke motheo oa linate, e etsang hore tlhahlobo ea eona e be ea bohlokoa ka ho khetheha:
Go/No-Go Gauge Testing: Sebelisa ho tsamaea (tsamaea) 'me u se ke ua{1}}sena{1}}hauge ho hlahloba khoele bakeng sa ho lumellana. The go gauge e lokela ho khona ho phunyeletsa hantle, ha no{3}}go gauge e sa lokela ho sebetsa ka botlalo.
Tlhahlobo ea Boemo ba Thread: Sebelisa profil ea khoele ho lekanya liparamente tse kang khoele ea profil ea khoele le ho kheloha ha molumo. Sena se loketse litlhoko tse phahameng- tse nepahetseng.
Teko ea Matla a Thread: Maemong a mang, ho thatafala ha sebaka se khoele ho hloka ho lekoa ho netefatsa ho hanyetsa le matla.
4. Tlhahlobo ea boima
Ho thatafala ha linate ho ama matla a eona a tsitsitseng le ho hanyetsa mokhathala. Mekhoa e latelang e sebelisoa hangata:
Rockwell Hardness Tester (HRB/HRC): E sebetsa ho carbon steel le alloy steel nuts ho metha ho thatafala ha bokaholimo.
Brinell Hardness Tester (HB): E loketse lisebelisoa tse bonolo (tse kang koporo le linate tsa aluminium), ho hlahloba kabo ea boima ba kakaretso.
Vickers Hardness Tester (HV): E loketse linate tse nyane kapa tse tšesaane{0}e tšesaane, e fana ka lintlha tse nepahetseng tsa bothata ba lehae.
5. Teko ea Thepa ea Mechini
Lithako tsa linate li ama ka kotloloho-ho jara boima ba tsona. Liteko tse tloaelehileng li kenyelletsa:
Teko ea Matla a Teka: Ho leka-bokhoni ba ho jara boima ba linate tse tlas'a moroalo ho sebelisoa mochini oa ho etsa liteko.
Teko ea Moroalo oa Bopaki: Ho sebelisa mojaro o itseng ho latela maemo (joalo ka ISO 898) ho etsa tlhahlobo ea deformation ea polasetiki ka har'a linate.
Teko ea Torque: Ho lekanya torque e sebelisitsoeng nakong ea ho tiisa le ho lokoloha ha nate ho netefatsa hore e fihlela litlhoko tsa kopano.
6. Teko ea Kalafo ea Bokaholimo (Haeba E le Teko)
Haeba nate e alafshoa ka liphekolo tse holim'a metsi joalo ka zinc plating, nickel plating kapa phosphating, tlhahlobo e eketsehileng ea hlokahala:
Botenya ba ho Koaheloa: U sebelisa tekanyo ea botenya ba ho penta, etsa bonnete ba hore seaparo se kopana le litlhoko (mohlala, "zinc plating" hangata e kholo ho feta kapa e lekana le 5μm.
Teko ea ho hanyetsa Corrosion: Thibelo ea mafome e hlahlojoa ka tlhahlobo ea spray ea letsoai (mohlala, 5% ea tharollo ea NaCl, lihora tse 48-96).
Teko ea Adhesion: E lekola kobo bakeng sa ho khomarela le ho thibela ho arohana.
7. Teko e sa Senyeheng (haeba ho hlokahala)
Bakeng sa linate tse nang le litlhoko tse phahameng tsa polokeho (joalo ka sepakapaka sa bohlokoa sa sefofane le likarolo tsa koloi), tse latelang li ka hlokoa:
Magnetic Particle Testing (MT): E lemoha bokaholimo kapa haufi le-mapetso a holim'a metsi.
Ultrasonic Testing (UT): E lemoha mefokolo ea ka hare e kang shrinkage cavities le inclusions.
X-Tlhahlobo ea Ray (RT): E loketse ho hlahloba sebopeho sa ka hare sa linate tse nepahetseng.
8. Tlhahlobo ea ho Qetela le ho Paka
Ka mor'a hore liteko tsohle li phethoe, linate tse tšoanelehang li etsa tse latelang:
Tekolo-ea sampole: Ho etsa lisampole ka mokhoa o sa reroang ho etsa bonnete ba ho lumellana.
Ho tshwaya le ho latedisa: Ho ngola ka tlhahisoleseding e jwalo ka ditlhahiso, beche, le letsatsi la teko ho thusa ho latedisa boleng.
Thibelo ea Rust le Packaging: Thibelo ea ho thibela mafome (mohlala, ho tlotsa oli) e etsoa ka moo ho hlokahalang, 'me ho sebelisoa mongobo- le ho phuthela ha shock{3}}.
Qetello
Ts'ebetso ea tlhahlobo ea linate e akaretsa likarolo tse ngata, ho kenyelletsa ponahalo, boholo, likhoele, boima, le thepa ea mochini, ho netefatsa polokeho le ts'epahalo lits'ebetsong tse sebetsang. Litlhoko tsa linate li ka fapana ho ea ka liindasteri tse fapaneng (tse kang tsa kaho, tsa likoloi le tsa lifofane), empa litekanyetso tse tiileng tsa tlhahlobo e ntse e le senotlolo sa ho netefatsa boleng.
