Yuav ua li cas xaiv txoj cai Fixture / Jig (工装夹治具)
Qhia meej rau "cov ntaub ntawv nkag" ntawm cov haujlwm -piece
Geometry: tag nrho qhov loj me, 3-D duab, phab ntsa thickness, tus naj npawb ntawm kev teeb tsa
Tolerance & nto tiav: lub fixture yuav tsum pab tsawg dua los yog sib npaug rau 30% ntawm tag nrho cov txheej txheem yuam kev pob nyiaj siv
Batch loj & takt lub sij hawm: tsab → modular los yog 3-D luam; siab ntim → siab hardened steel
Xaiv txoj hauv kev ua ntej clamping txoj kev
Siv "3-2-1" lossis "ib lub dav hlau + ob lub qhov" txhawm rau txwv rau qib kev ywj pheej; qhov chaw pins thiab so pads yuav tsum adjustable los yog hloov tau rau hnav them nyiaj
Ua ib qho chaw nyob - xam yuam kev: Δloc=f (datum shift + pin clearance + part variation). Yog tias Δloc > 1/3 feem kam rau ua, rov tsim cov txheej txheem datum
Xaiv clamping quab yuam uas yog "tsuas yog txaus"
Txoj cai ntawm tus ntiv tes xoo: Fclamp ≈ 3 × txiav quab yuam nyob rau hauv cov kev taw qhia tsis muaj zog
Rau txhuas lossis nyias- cov phab ntsa siv cov khoom siv qis- quab yuam toggle, pneumatic (0.4–0.6 MPa) lossis hydraulic (2–4 MPa) clamps kom tsis txhob muaj kev cuam tshuam; rau hnyav hlau forgings siv siab -lub zog hydraulic viav vias kheej kheej
Ib txwm ua kom lub clamping vector nrog lub dav hlau nrhiav kom txo qis lub sijhawm khoov
Xyuas fixture stiffness tiv thaiv txiav quab yuam spectrum
Yam tsawg kawg nkaus zaus fn Ntau dua lossis sib npaug rau 300 Hz rau kev ua haujlwm siab - ceev; ntxiv ribs los yog lub thawv qauv yog modal xeem tsis tau
Static deflection nyob rau hauv max load Tsawg dua los yog sib npaug rau 0.01 hli ntawm lub cuab yeej
Txiav txim siab ntawm phau ntawv, ib nrab- tsis siv neeg lossis tag nrho- tsis siv neeg
Phau ntawv: toggle, cam, wedge- pheej yig, ceev rau <500 pcs
Semi-auto: pneumatic nrog 5/2- txoj kev valve-zoo rau 500–10 000 pcs
Siab -auto: xoom-point lossis rub-stud system ntawm HMC- tso cai 60 s pallet hloov, kev lag luam siab dua 10 000 pcs
Nyiam cov khoom siv thiab cov khoom siv modular
80% ntawm cov khoom siv ua haujlwm (nrhiav tus pins, clamps, daim phiaj hauv paus) yuav tsum yog cov khoom catalog- txiav lub sijhawm tsim 40% thiab tus nqi 25%
Siv aluminium profile rau qis -mass 3-D luam tawm jigs thaum lub voj voog < 30 min; hloov mus rau hardened 45 # lossis 40Cr thaum ntim txhua xyoo > 5 000
Ntsuam xyuas thermal & chip tswj
Txoj kev khiav dej txias yuav tsum tsis txhob thawb cov chips nyob rau hauv cov ntaub qhwv; ntxiv 1-2℃sloped nto thiab ntws qhov
Rau titanium los yog CFRP, muab cov thermal rho tawm pads kom qhov kub thiab txias tsis pub dhau ± 2 degree
Txheeb xyuas sai sai -hloov & ua yuam kev- pov thawj cov yam ntxwv
Xim -coded clamps, ib qho - txoj kev ntxig thiab RFID cim npe tiv thaiv kev thauj khoom tsis raug
Hloov cov ntaub qhwv yuav tsum hloov pauv tsis pub dhau 3 min yam tsis tau tshem tawm cov khoom siv los ntawm lub tshuab
Ua ib qho kev ntsuam xyuas nyiaj txiag
Cfixture Tsawg dua lossis sib npaug rau (Cscrap + Crework) khaws tseg × them nyiaj- lub sijhawm rov qab (feem ntau 6–12 lub hlis)
suav nrog tus nqi khaws cia, kev saib xyuas thiab rov-calibration
Cov ntaub ntawv thiab digitize
Tsim ib daim ntawv hla tebchaws: 3-D qauv, daim nqi ntawm cov ntaub ntawv, clamping sequence, max torque, sijhawm tshuaj xyuas
Upload rau MES kom tib cov ntaub ntawv muaj nyob rau yav tom ntej kev txiav txim rov qab los yog tus muam cov nroj tsuag
Ua raws li kaum kauj ruam saum toj no thiab koj yuav tsis tu ncua xaiv (los yog tsim) lub fixture / jig uas yog, kev lag luam thiab ntau lawm-npaj.
