Tus yuam sij kom txo tau tus nqi thiab lub sij hawm txhuas ntawm cov ntawv hlau yog qhov sib txawv ntawm "pwm" thiab "jig" siv thaum ua cov khoom. Tsis tas li ntawd, "tus txheej txheem npaj tus txiv neej-teev" thaum siv pwm thiab jigs tseem yuav cuam tshuam rau tus nqi thiab tus nqi. Kuv yuav qhia cov ntsiab lus tsim uas tsis tuaj yeem tsis quav ntsej yog tias koj xav tswj tus nqi ntawm cov ntawv hlau thiab ua kom lub sij hawm luv luv ntawm ob feem ntawm pwm thiab jigs.
Cov duab sib txawv ntawm tus nqi thiab lub sij hawm txhuas raws li hom pwm
Los ntawm kev hloov pauv me ntsis, hom "pwm" siv los ua qhov sib txawv, thiab "tus txiv neej-teev" tuaj yeem txo qis. Yog tias koj tuaj yeem siv "tus qauv pwm" thiab tsim "tsawg tus txiv neej-teev", koj tuaj yeem txwv tus nqi thiab lub sijhawm khoom xa tuaj.

Daim duab Case (1) Nce qhov siab khoov
Tsuas yog los ntawm kev nce qhov siab ntawm 1 hli, nws tuaj yeem ua nrog cov pwm pwm, txo cov txiv neej-teev, txo tus nqi, thiab txo lub sijhawm xa khoom.
(Qhov no, los ntawm kev siv tus qauv tsim nrog qhov siab ntawm 8.3mm lossis ntau dua, cov pwm thiab cov txiv neej-teev hloov pauv, tab sis qhov siab yuav txawv nyob ntawm tus qauv tsim.)
duab
Daim duab Case (2) Txhim kho lub kaum sab xis
Nrog tsuas yog nce ntawm 30 degree, cov qauv pwm tuaj yeem siv tau, uas txo cov txiv neej-teev, txo tus nqi, thiab ua kom lub sij hawm luv luv.
(Qhov no, los ntawm kev siv tus qauv tsim nrog lub kaum sab xis ntawm 110 degree lossis ntau dua, cov pwm thiab cov txiv neej-teev sib txawv, tab sis lub kaum sab xis sib txawv nyob ntawm tus qauv tsim.)
duab
Cov duab sib txawv ntawm tus nqi thiab lub sijhawm ua haujlwm raws li qhov xav tau ntawm cov khoom pabcuam pabcuam
Ib qho ntawm cov ntsiab lus uas tuaj yeem txo tus nqi thiab ua kom luv luv lub sij hawm ntawm cov ntawv hlau yog qhov sib txawv ntawm "jigs" siv thaum ua cov khoom thiab lawv "kev npaj txiv neej-teev".
Cov txheej txheem kev npaj ua ntej khoov ntawm ib txoj hauj lwm raug xaiv yog siv "jig" los kho cov khoom siv (workpiece). Muaj ob hom "fixtures", mus tas li thiab pab, thiab yog tias nws tsim raws li lub tswv yim ntawm kev siv tsuas yog "fixtures tas mus li", nws kuj tuaj yeem txo qhov kev npaj cov txiv neej-teev, txo tus nqi ntawm cov khoom, thiab txo cov hlau lead. sij hawm. Cov pej xeem account "Mechanical Engineering Literature", chaw nres tsheb roj rau cov kws ua haujlwm!

Duab Tsis hnov ntawm? ! Taw qhia ntawm jigs siv nyob rau hauv dabtsi yog khoov ua!
[Daim duab. 1] Kab rov tav saib ntawm lub workpiece khoov nrog ib tug tuag
duab
Nyob rau hauv dabtsi yog khoov ua siv lub tshuab ua, nws yog ib qho tseem ceeb kom kho lub workpiece nrog ib tug jig
Fig. 1 yog ib qho kev pom ntawm lub workpiece (txiv kab ntxwv ib feem) khoov nrog ib tug tuag raws li pom los ntawm lateral kev taw qhia.
Txhawm rau khoov lub workpiece ntawm txoj kab dub dotted, taw qhia lub workpiece mus rau "qhov chaw ruaj khov" hu ua lub nraub qaum nres nyob rau sab hauv ntawm lub workpiece, abut thiab kho nws nyob rau hauv cov kev taw qhia ntawm xub, thiab nias lub pwm rau. dub dotted kab (bending kab) rau khoov.
Yog hais tias lub workpiece deviates thaum lub sij hawm ua, lub dabtsi yog khoov qhov yuav deviate, yog li nws yuav tsum tau ruaj khov. Yog hais tias lub workpiece tsis tuaj yeem ruaj khov thiab cov txheej txheem khoov tau ua nyob rau hauv lub xeev tsis ruaj khov, txoj kab bending yuav inclined, uas ua rau txo qhov raug xws li qhov tsis xws luag.
[Daim duab. 2] Ib qho kev pom ntawm cov txheej txheem khoov ntawm lwm cov workpieces pom los ntawm saum toj no
duab
"Auxiliary Fixtures" yuav tsum tau thaum lub workpiece tsis tuaj yeem kho siv tsuas yog "Permanent Fixtures"
Daim duab 2 yog ib daim duab ntawm kev khoov ntawm lwm cov workpieces pom los ntawm saum toj no.
Raws li pom nyob rau hauv daim duab 2, thaum kawg nto (liab kab) ntawm lub workpiece muaj ib tug duab uas yog ib qho nyuaj rau abut tiv thaiv lub backstop los yog abutting nto yog me me, nws yog ib qhov nyuaj rau kho lub workpiece tsuas yog siv lub "mus tas li clamp". . Nyob rau hauv cov ntaub ntawv no, "auxiliary jig (xiav ib feem)" kuj tseem siv, thiab cov txheej txheem kev npaj xws li kos lub bending txoj hauj lwm yuav tsum tau.
"Kev npaj cov txheej txheem tsim nyog=nce hauv tib neeg-teev" tau dhau los ua qhov tseem ceeb ua rau cov nqi siab thiab lub sijhawm ua haujlwm ntev.
[Daim duab 3] Tsim cov ntsej muag sib luag
duab
Tsim cov ntsej muag kawg thaum uas tig mus rau txoj kab khoov, yog li tshem tawm qhov xav tau ntawm "ntsuas clamps" thiab tso cai rau lub workpiece tuav nyob rau hauv qhov chaw siv tsuas yog "taw clamps"
Raws li pom nyob rau hauv daim duab 3, los ntawm kev tsim qhov kawg nto (liab kab) ntawm lub workpiece uas abuts tiv thaiv lub backstop raws ib tug ncaj kab uas tig mus rau lub dabtsi yog khoov kab (dub dotted kab), lub workpiece yuav tsum tau tsiv mus nyob tsuas yog siv lub "mus tas li fixture" tsis muaj qhov "auxiliary fixture". Nws yog ruaj khov, yog li cov txheej txheem khoov nws tus kheej tuaj yeem ua tiav yooj yim yam tsis muaj kev txawj tshwj xeeb.
Pom zoo mob rau cov duab
Nws raug pom zoo tias qhov ntev (A) ntawm lub ntsej muag kawg yog ntau tshaj li ib nrab ntawm qhov ntev (B) ntawm qhov khoov (A Ntau dua lossis sib npaug rau B÷2).
Qhov no yog vim qhov chaw (A) abutting tiv thaiv lub backstop yog loj, thiab nws yog ib qho yooj yim mus kho lub workpiece.
[Daim duab 4] Tsim kom muaj lub ntsej muag sib luag nrog lub ntsej muag
duab
Nyob rau hauv rooj plaub uas lub ntsej muag kawg uas pom hauv daim duab 3 tsis tuaj yeem tsim tau, raws li qhia hauv daim duab 4, los ntawm kev tsim ib lub protrusion parallel mus rau txoj kab dabtsi yog khoov (dub dotted kab), lub workpiece tuaj yeem kho nrog tsuas yog cov "jig tas mus li" tsis muaj "auxiliary jig" yuav ruaj.
< Recommended conditions for shape >
Nws raug pom zoo tias qhov ntev thiab qhov dav (C) ntawm cov duab protrusion yog 10 hli lossis ntau dua, thiab qhov kev ncua deb (D) los ntawm cov duab sab nrauv mus rau qhov protrusion yog 100 hli lossis tsawg dua.
※ Thaum qhov kev ncua deb (D) los ntawm cov duab sab nrauv mus rau qhov protrusion loj los yog khoov ntev (E) ntev, lub workpiece yuav tuaj rau hauv kev sib cuag nrog lub mounting ib feem ntawm lub rear stopper, yog li ntawd lub workpiece tsis tuaj yeem ruaj khov, thiab dabtsi yog khoov tej zaum yuav ua tsis tau.
Piv txwv (3) Tsim ib lub ntsej muag kawg thaum uas tig mus rau txoj kab khoov (dub dotted kab)
Los ntawm kev tsim lub ntsej muag kawg (qhov uas abuts lub backstop) thaum uas tig mus rau txoj kab khoov, tsis tas yuav tsum muaj "secondary clamp". Workpieces tuaj yeem kho tau tsuas yog siv "jigs mus tas li", txo cov txheej txheem kev npaj tus txiv neej-teev thiab txo tus nqi thiab lub sijhawm xa khoom.
Daim duab piv txwv (4) Tsim ib qho kev sib txuas mus rau txoj kab khoov (dub dotted kab)
Yog tias nws tsis tuaj yeem tsim lub ntsej muag kawg thaum uas tig mus rau txoj kab khoov (qhov uas ua rau lub nraub qaum), tsim kom muaj qhov sib npaug sib npaug, yog li tshem tawm qhov xav tau ntawm "secondary clamp". Workpieces tuaj yeem kho tau tsuas yog siv "jigs mus tas li", txo cov txheej txheem kev npaj tus txiv neej-teev thiab txo tus nqi thiab lub sijhawm xa khoom.
