Tshuab pins - tseem hu ua tus pin fasteners los yog fastening pins - yog tshwj xeeb fasteners siv los ua kom zoo thiab txuas ob feem los yog sib dhos ua ke. Muaj nyob rau hauv ib nrab-ntev thiab ceev-tso qauv, cov fasteners no yuav tsum tau ntxiv siab los yog cuab yeej rau nruab thiab tshem tawm (xws li, ib nrab mus tas li) los yog muaj lub caij nplooj ntoos hlav-loaded mechanism uas xauv lawv nyob rau hauv qhov chaw kom yooj yim installation thiab tshem tawm (ie, ceev-tso tawm).
Ntxiv nrog rau cov yam ntxwv hais saum toj no, cov khoom siv no muaj ntau qhov ntau thiab tsawg thiab cov khoom siv - suav nrog hlau, yas, thiab ntoo - nrog rau cov qauv sib txawv kom haum rau ntau yam kev siv. Kev txiav txim siab zoo tshaj plaws ntawm lub tshuab pins siv yog nyob ntawm qhov yuav tsum tau ua ntawm daim ntawv thov, vim txhua hom tus pin yog siv los ua haujlwm sib txawv thiab kev ua haujlwm.
Tshuab pin fasteners feem ntau siv hauv kev lag luam thiab kev lag luam tuaj yeem muab faib ua ntau pawg, suav nrog:
Cotter tus pin
Nrhiav tus pin
Hook thiab kev ruaj ntseg pin
Nrhiav tus pin
Caij nplooj ntoos hlav pin
Cov ntu hauv qab no piav qhia txhua yam ntawm cov tshuab pin saum toj no thiab muab cov piv txwv ntawm lawv cov subtypes.
Cotter Pin
Cotter pins, tseem hu ua cotter keys los yog hlau clips, yog ob-hlau hlau fasteners siv nyob rau hauv lub tshuab dhos daim ntaub ntawv los pab tuav qhov chaw los yog lwm yam fasteners (piv txwv li, clevis pins los yog slotted ceev) nyob rau hauv qhov chaw thiab tiv thaiv lawv los ntawm loosening lub sij hawm. Cov fasteners no muaj nyob rau hauv kev tso tawm sai, semi-circular los yog ncig tsim thiab feem ntau yuav tsum tau pre-drilling los yog qhwv lub ncej sib dhos thaum lub sij hawm installation.
Feem ntau hom cotter pin - lub cotter pin - muaj lub taub hau sib npaug thiab hloov tau yooj yim. Cov khoom no ua rau nws tsim nyog rau kev ntxig thiab kev ruaj ntseg ua ntej cov khoom siv tho, nrog rau kev xauv lwm cov fasteners.
Qee yam ntawm cotter pin hom muaj xws li hneev khi pins, compression pins, hairpin splits, nplhaib splits, thiab twist pins.
Pin
Dowels yog luv luv, ncaj, thiab cylindrical rods siv los pab kho qhov chaw ntawm lub tshuab ua ntej lawv tuav ua ke nrog lwm cov fasteners, xws li cov ntsia hlau los yog bolts. Cov fasteners no muaj nyob rau hauv high-precision tapered, slotted, helical, stepped thiab grooved designs, feem ntau nrog ib tug siab coefficient ntawm kev sib txhuam, tuav cov khoom nyob rau hauv qhov chaw. Qee cov ntawv thov rau dowel pins suav nrog cov rooj tog sib dhos thiab siv los ua cov pob khawm yooj yim lossis cov ncej.
Feem ntau siv nyob rau hauv mechanical engineering, tus pin tapered yog ib hom kev nrhiav tus pin uas muaj txoj kab uas hla loj dua ntawm ib kawg thiab tapers mus rau qhov kawg me. Muaj nyob rau hauv unthreaded thiab ib leeg- thiab ob-kawg threaded versions, cov pins yog haum rau nrhiav thiab txuas cov khoom nyob rau hauv cov khoom xws li lub log thiab levers rau shafts.
Tsav pins, slotted pins, thiab knurled pins yog ib co lwm yam nrhiav tus pins muaj.
Hook thiab Lynch Pin
Ob leeg hitch pins thiab kev ruaj ntseg pins yog zoo sib xws fasteners nyob rau hauv daim ntawv thiab muaj nuj nqi; cov ceev-tso tawm, cylindrical thiab (feem ntau) ncaj pins yog muab tso rau hauv pre-drilled mating qhov kom ruaj ntseg ib ntus lossis txuas cov khoom.
Ob hom pins txawv nyob rau hauv lawv lub xauv mechanism; thaum hitch pins xav tau ib qho ntxiv fastening tivthaiv (feem ntau yog ib tug cotter tus pin) rau xauv rau hauv qhov chaw, kev ruaj ntseg pins (tseem hu ua kev ruaj ntseg pins los yog kev ruaj ntseg pins) muaj ib tug integrated locking mechanism.
Piv txwv li, ib tug clevis pin yog ib tug hitch pin uas yog xauv rau hauv qhov chaw nrog ib tug cotter tus pin. Feem ntau, lawv tau siv los ua ib feem ntawm clevis fastening system los pab kom tus pin txuas mus rau lwm cov khoom siv, xws li cov khoom siv crane lossis plow. Kev ruaj ntseg pins, ntawm qhov tod tes, feem ntau yog siv rau ntawm lub tog raj kheej lossis lub log thiab siv cov khoom sib txuas uas txuas rau hauv qhov chaw thiab tiv thaiv cov fasteners los ntawm loosening thiab sib dhos los ntawm kev sib tsoo.
Lwm cov piv txwv ntawm kev sib txuas cov pins thiab kev ruaj ntseg pins suav nrog dowel pins, snap pins, thiab toggle pins.
Dowel Pin
Dowel pins yog siv los ua txoj haujlwm, sib dhos thiab tuav ob lub workpieces ua ke kom nruj nruj. Muaj nyob rau hauv ntau yam sib txawv tsim thiab configurations - nrog rau lub taub hau thiab shank style, raws li zoo raws li phau ntawv, pneumatic, hydraulic, thiab hluav taws xob ua kom - cov cylindrical fasteners yog haum rau ntau yam kev siv.
Qee cov subtypes ntawm ob hom pins muaj xws li cov mos txwv pins, clamping pins, tapered dowel pins, drift pins, L-pins, thiab T-pins.
Caij nplooj ntoos hlav Pin
Lub caij nplooj ntoos hlav tus pin yog qhov chaw tus pin nrog lub taub hau, hollow cylindrical tsim thiab muaj nyob rau hauv ob qho tib si dov thiab dov versions. Raws li lub npe qhia, lub kauj lub caij nplooj ntoos hlav tus pin yog ua los ntawm cov khoom siv hlau (feem ntau yog hlau), uas yog dov rau hauv cov duab cylindrical, thaum tus pin coiled (tseem hu ua lub caij nplooj ntoos hlav pin) yog dov rau hauv cov duab.
Cov hom fasteners no yog tus nqi-zoo thiab yuav tsum tau npaj me ntsis ua ntej siv, thiab muaj ntau daim ntawv thov, los ntawm cov khoom siv hluav taws xob mus rau cov ntawv thov hlau fabrication.
Lwm Hom Pins
Ntxiv rau cov hom saum toj no, muaj lwm cov pins muaj rau kev lag luam tshwj xeeb thiab kev lag luam. Cov pins no muaj xws li ejector pins, pivot pins, shear pins, thiab weld pins.
