Ubona 'izikrufu zomatshini wentloko engqukuva' kwiphepha elithile kwaye ucinge, 'idome elilula, elifakwe okanye iPhillips, liyifumene.' Ngumgibe wokuqala lowo. Kwilizwe lokwenyani lendibano, loo ngcinga inokubiza ixesha, imali, kunye nokukhungatheka okukhulu xa inxalenye ingasebenzi. Asiyomilo nje; yiseti yokulalanisa phakathi kokubamba, ukukhutshwa, ukubandakanyeka kwesixhobo, kunye nokubonakala kokugqibela ukuba abantu abaninzi bokuthenga, ngokungafihlisiyo, bagubungele de babambe intloko ehlutyiweyo okanye bajongane nomba wokufaneleka emgceni.

Iprofayile yiNqaku

Makhe sicacise. Iklasikhi isikrufu somatshini wentloko engqukuva inentloko ene-hemispherical kunye nomphezulu osicaba ngaphantsi. Isitshixo asiyiyo idome oyibonayo, yilaa cala lisezantsi lisicaba. Yenzelwe imingxuma countersunk? Hayi, akunjalo. Oko kuxutywa okuqhelekileyo kunye nezikrufu zentloko embhoxo. Intloko engqukuva ihleli phezu kwendawo yokusebenza. Oko kuthetha ukuba ufuna imvume eyaneleyo ngaphezu komphezulu. Ndibone uyilo apho injineli ichaze intloko engqukuva yomqolo obuyiselweyo, kukufumana kuphela isixhobo sokuhlanganisa asikwazanga ukufumana i-angle ethe tye kwi-drive kuba idome ibibetha udonga lomngxunya. Rework isixeko.

Ubude bentloko kunye nomlinganiselo wedayamitha zibalulekile kunokuba ucinga. Idome enganzulwanga, ebanzi ibonelela ngeprofayile esezantsi kodwa isayizi encinci yesokethi yedrive, ibeka umngcipheko wokuphuma. Idome ende, emxinwa ikunika ikhefu elinzulu lokuqhuba (ilungele itorque) kodwa ivele ngaphezulu. Kwinto efana nokukhusela i-nameplate okanye isigqubuthelo segeyiji ecekethekileyo apho ufuna ukubukeka okugudileyo, okugqityiweyo kodwa awukwazi ukumelana nesiseko sesinyithi, intloko engqukuva kukuya kuyo. Kodwa kufuneka uyibhanqe kunye newasha ukuba i-substrate ithambile, okanye loo ndawo ibambekayo iyakugrumba nje.

Ukukhetha izinto eziphathekayo kudlala nakule nto. Kwinsimbi engenasici, ngakumbi i-series ye-300, isinyithi sinokuba nenyongo. Ukuba uqhuba insimbi engenasici isikrufu somatshini wentloko engqukuva Kwintongomane yentsimbi engatyiwayo okanye umngxunya ocofayo ngaphandle kwesithambiso esifanelekileyo okanye ukutyabeka, unokuyitshisa into leyo phambi kokuba ubethe i-spec torque. Isifundo esifundwe kabuhlungu kumsebenzi waselwandle. Sitshintshele kwi-zinc-plated carbon steel screw kwisicelo, ingxaki iphelile. Imilo yentloko ayizange itshintshe, kodwa umxholo wezinto eziphathekayo wenze wonke umahluko.

Iintlobo zeDrayivu kunye neNyaniso yokubamba

Slotted, Phillips, Pozidriv, Allen (socket cap). Uhlobo lokuqhuba lutshatile entloko. Isikolo esidala esifakwe kwintloko ejikelezayo yintlungu yokuvelisa. Umqhubi wakho uyatyibilika, wonakalise idome, kwaye ukhangeleka kakubi. IPhillips ingcono kodwa isetyekele ekuphumeni phantsi kwetorque ephezulu. Kuyo nayiphi na indibano enzulu, ufuna i-socket drive. Kodwa nantsi into yokubambisa: i-socket (Allen) idrayivu kwintloko engqukuva ithetha ubungakanani besitshixo esincinci se-hex xa kuthelekiswa nesikrufu sesokethi sentloko yesokhethi yedayamitha yomzimba ofanayo, kuba iindonga zesokethi kufuneka zilingane ngaphakathi kokugoba kwedome.

Oku kukhokelela kumbandela osebenzisekayo wokufumana ulwazi. Udinga intsimbi yodidi oluphezulu lwe-alloy yesikrufu ukuze ufezekise amandla afunekayo okubamba ngaphandle kokukhulula i-hex yangaphakathi. Ndikhumbula ibhetshi evela kumboneleli oya kuhlala engenagama apho ubunzulu besokethi ye-hex babungaphantsi komatshini ngesiqingatha semilimitha. Isitshixo asizange sihlale ngokupheleleyo, sahluba umzamo wokuqala wokuqhuba, kwaye kwafuneka sihlole ngesandla kwaye sale iiyunithi ezingama-20,000. Ukusilela kwakungekho kumsonto okanye kumandla okuqina; kwakuloo nto incinci, ihlala ingahoywa, idrayivu.

Yiyo loo nto xa ufumana umthengisi ofumana ezi nuances ngokufanelekileyo, unamathela kubo. Indawo efana I-Sunnian Zitai Festener Fishaner Comment Com., esekelwe kwi-hub enkulu ye-fastener yase-China e-Yongnian, e-Hebei, iyayiqonda le nto kwisikali semveliso. Indawo ezikuyo kufutshane neendlela ezinkulu zothutho asiyondawo yokuthengisa nje; ithetha ukuba zifakwe kwi-ecosystem yesixokelelwano sobonelelo apho ezi nkcazo zixoxwa mihla le kwimigangatho yefektri. Ukujonga ikhathalogu yabo kwi I-Zitafasteners.com, ungabona ingqwalaselo yokuqhuba inkcazo kunye nentloko yeprofayile nakwizinto eziqhelekileyo. Lilo nqanaba legranular lolawulo elahlula umthengisi wempahla kwiqabane lemveliso.

Ingxaki Yokugqibezela Akukho Bani Uthetha Ngayo

Ukutyalwa kunye nokwaleka. Intloko engqukuva, enomgangatho wayo ogobileyo oqhubekayo, yomelele ukuyipleyitha ngokulinganayo kunesikrufu esinentloko ecaba. I-Electroplating ithande ukwakha kwimiphetho kunye neekona. Kwintloko engqukuva, 'ungqameko' yisangqa esipheleleyo apho idome idibana neshanki. Unokufumana i-ridge ephawulekayo okanye indawo encinci apho. Kwizicelo zokuhombisa okanye apho ukuxhathisa kwe-corrosion kubaluleke kakhulu, oku kuyinkxalabo yokwenene.

Sasineprojekthi yeendawo ezivaliweyo zangaphandle zisebenzisa i-zinc-flake coated (Geomet) izikrufu ezingqukuva zentloko yokugqiba emnyama. Iisampulu zokuqala zazigqibelele. Ukuqhuba kwemveliso kubonise utshintsho oluncinci kwi-sheen kunye nobukhulu obujikeleze eso sidibaniso sentloko ukuya kwi-shank. Yayingacacanga, kodwa phantsi kokukhanya okuthile, isiqhoboshi sasibonakala 'sijingiwe.' Umthengisi wezogquma utyhola ijiyometri yesikrufu; umenzi wesikrufu utyhola inkqubo yokwaleka. Isicombululo? Ukulungelelanisa ukuxinana kweerakhi kunye nokuphazamiseka ngexesha lokugquma kwelo candelo likhethekileyo lejometri. Yongeza iveki kwixesha eliphambili. Ngoku yinto yomgca kwi-spec yethu: Ukwaleka okufanayo kufuneka kugcinwe ngaphezulu kweprofayile yentloko epheleleyo.

Kulapho isiseko soveliso senkampani efana neZitai sisebenza khona. Ukuba seYongnian, banofikelelo olukhawulezileyo kuthungelwano lweengcali zeplating kunye nonyango. Bangakwazi ukulungisa le miba yenqanaba lenkqubo kuba babona umthamo kunye nokwahluka. Ivenkile encinci, ekwanti isenokungabi nayo le ecosystem ekunokungqiyama kuyo.

Iza kuyisebenzisa nini (kwaye imele ibaleke nini)

Ke emva kwayo yonke le nto, iphi i isikrufu somatshini wentloko engqukuva uyigcine? Ilungele ukuncamathelisa amacandelo kumphezulu ongenakuguqulwa nge countersink. Cinga ngokufaka i-hinge plate kwisakhelo somnyango womthi, okanye ukukhusela isibiyeli sentsimbi kwilitye okanye kwikhonkrithi (kunye ne-anchor, kunjalo). Idome ibonelela ngenkangeleko egqityiweyo engaphantsi kwe-snag-prone kunentloko yepani. Ikwaluncedo nakwizivalo zombane apho intloko egudileyo ikhuseleke ngakumbi kwaye kunqabile ukubamba iingcingo.

Ufanele ukuphephe nini? Xa ufuna ukugqiba ukugungxula (sebenzisa intloko ecaba okanye embhoxo). Xa ufuna i-torque ephezulu kakhulu kunye ne-protrusion encinci (i-socket head cap screw ingcono, nangona ibambelela ngaphezulu). Xa udibanisa izinto ezibhityileyo njengeeplastiki ezithile okanye izinto ezidityanisiweyo-amandla okuthwala agxininisiweyo angaphantsi kweflethi anokuqhekeka loo nto. Soloko usebenzisa iwasha okanye indawo enkulu yokuthwala.

Into ethathwayo kukuba ungaze uyiphathe njengesiqhoboshi segeneric. Ixabiso layo likwijometri ethile kwiimeko ezithile. Ukuyichaza ngokuchanekileyo-kunye ne-drive efanelekileyo, izinto eziphathekayo, i-plating, kunye nokuqonda okucacileyo komxholo wendibano-yinto ekwahlula ukuyila okusebenzayo ukusuka kwenye ekufuneka ihlaziywe rhoqo kwintsimi. Licandelo elincinci, kodwa njengazo zonke izinto kuyilo lomatshini, usathana usezinkcukacha ozifundayo ngokuzenza zingalunganga kuqala.
