Cov Pins Cylindrical: Kev Ntsuas thiab Lub Zog
Cov koob cylindrical yog ib qho ntawm cov khoom siv feem ntau siv hauv kev tsim khoom. Nws txoj kev tsim qauv yooj yim tab sis ua tau zoo ua rau nws zoo tagnrho rau ntau yam kev siv. Cov koob no feem ntau siv los sib dhos thiab ruaj ntseg cov khoom, xyuas kom meej tias lawv nyob hauv qhov chaw raug thaum lub sijhawm sib dhos thiab ua haujlwm. Cov koob cylindrical muaj ntau qhov ntau thiab tsawg thiab cov ntaub ntawv, cia koj xaiv cov koob zoo meej rau koj cov kev xav tau tshwj xeeb.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov cylindrical pins yog lawv qhov yooj yim ntawm kev teeb tsa. Lawv tuaj yeem nias lossis kov rau hauv qhov chaw siv cov cuab yeej hlau mos, ua rau cov txheej txheem sib dhos sai thiab ua haujlwm tau zoo. Thaum ntsia tiav lawm, cov cylindrical pins muab kev sib txuas ruaj khov thiab ruaj khov uas tuaj yeem tiv taus lub zog loj thiab kev co.
Cov Pins Tapered: Kev Siv Tau Ntau Yam thiab Kev Hloov Tau
Cov koob tapered, tseem hu ua cov koob tapered, muab kev sib xyaw ua ke ntawm kev ua tau ntau yam thiab kev hloov pauv tau. Lawv cov qauv tapered tso cai rau lawv siv rau hauv cov ntawv thov uas xav tau kev sib haum xeeb thiab ruaj ntseg. Cov koob tapered muaj txiaj ntsig tshwj xeeb hauv cov xwm txheej uas xav tau kev sib dhos thiab kev rhuav tshem ntawm cov khoom, vim lawv cov qauv tsim ua rau lawv yooj yim rau ntxig thiab tshem tawm.
Ib yam li cov koob cylindrical, cov koob tapered tuaj yeem ntsia tau los ntawm kev stamping lossis tapping. Lawv cov duab tapered ua kom muaj kev sib haum xeeb, txo qhov kev pheej hmoo ntawm kev xoob dhau sijhawm. Cov koob tapered muaj nyob rau hauv ntau yam khoom siv, suav nrog ntoo thiab hlau, ua rau lawv haum rau ntau yam kev siv los ntawm kev sib dhos rooj tog mus rau kev tsim kho tshuab.
Cotter Pins: Kev Nyab Xeeb thiab Kev Ntseeg Tau
Cov koob txuas (cotter pins), tseem hu ua cov koob txuas (cotter pins), yog cov khoom siv tseem ceeb uas siv los tuav cov khoom kom ruaj khov. Cov koob txuas no feem ntau siv ua ke nrog lwm cov khoom siv xws li cov ntsia hlau thiab cov txiv ntoo kom tiv thaiv lawv kom tsis txhob xoob thaum ua haujlwm. Cov koob txuas (cotter pins) yog tsim los nrog cov qhov kawg uas tuaj yeem khoov tau kom xauv lub koob txuas rau hauv qhov chaw, muab ib txheej kev ruaj ntseg ntxiv.
Cov koob txuas Cotter siv dav hauv ntau yam lag luam, suav nrog tsheb, aerospace thiab kev tsim kho. Lawv cov qauv yooj yim tab sis zoo ua rau lawv yooj yim rau kev teeb tsa thiab tshem tawm, ua kom cov khoom tseem nyob ruaj ntseg txawm tias nyob rau hauv cov xwm txheej nyuaj. Cov koob txuas Cotter muaj ntau qhov ntau thiab tsawg thiab cov ntaub ntawv, cia koj xaiv cov koob txuas zoo meej rau koj daim ntawv thov tshwj xeeb.
Dowels: Kev Ua Kom Tiav Hauv Kev Ua Haujlwm Ntoo Thiab Lwm Yam
Cov dowels yog lwm hom dowel tseem ceeb uas feem ntau siv rau hauv kev ua haujlwm ntoo thiab kev tsim kho. Cov dowels no feem ntau yog conical, pointed lossis cylindrical thiab siv los ntsia hlau lossis ruaj ntseg cov ntoo boards, vuas, khau khau, khau uppers, rooj tog moldings thiab Cheebtsam. Dowels kuj tseem siv los txhaws cov qhov, muab kev sib txuas tsis muaj teeb meem thiab ruaj ntseg ntawm cov Cheebtsam.
Cov dowels ntoo nrov heev rau kev sib dhos rooj tog, vim lawv muab kev sib txuas ruaj khov thiab ruaj khov yam tsis tas yuav siv cov khoom siv ntxiv.
