High-Precision Shim Thickness Measurement Station - Granite-based Comparator Rau Shims, Washers & Spacers hauv Common Rail Systems

Lub shim txo qis - ib lub nplhaib nyias ntawm cov hlau tawv tawv lossis tooj dag - yog qhov kev txiav txim siab tsis zoo ntawm cov twj tso kua mis pre-load, twj tso kua mis plunger clearance, thiab valve tsheb ciav hlau geometry hauv cov tsheb ciav hlau. Qhov yuam kev 0.02 hli nyob rau hauv lub injector tuav-down shim txhais mus rau 200-bar variation nyob rau hauv txhaj tshuaj; ib tug 0.01 hli sib txawv nyob rau hauv lub twj tso kua mis plunger shim hloov lub sij hawm ua ntej los ntawm ze li ntawm 1℃crank lub kaum sab xis. Txawm li cas los xij, feem ntau cov kev cob qhia ntsuas cov khoom tseem ceeb no nrog cov callipers lossis micrometers yooj yim - cov cuab yeej uas qhia cov neeg ua haujlwm-nyob ntawm qhov siab, qhov kub thiab txias, thiab qhov yuam kev parallax. Peb Lub Chaw Ntsuas Ntsuas tau txheeb xyuas qhov kev ua haujlwm no nrog lub hauv paus tawv granite, lub tshuab hluav taws xob sib piv siab, thiab lub caij nplooj ntoos hlav-loaded anvil uas siv qhov sib npaug 5 N ntsuas lub zog. Qhov no tsis yog ib qho cuab yeej precision; nws yog lub chaw nres tsheb metrology lub hom phiaj-tsim rau qhov chaw pabcuam diesel, xa cov chav kuaj-qib qhov tseeb ntawm lub rooj zaum rhiav.

Qhov chaw ntsuas lub hauv paus yog ib qho precision-av granite slab (qib 0, 400 × 300 × 80 mm) uas muab ib tug flatness ntawm 2 µm thoob plaws nws tag nrho saum npoo. Granite yog xaiv los ntawm cam khwb cia hlau rau nws superior thermal stability (coefficient ntawm expansion 4.7 × 10⁻⁶ / degree, piv rau 11 × 10⁻⁶ rau steel) - ib qho tseem ceeb ntawm qhov chaw rhiav qhov kub thiab txias ntawm 10-15 degree. Lub slab yog mounted rau peb adjustable theem taw nrog vibration-damping pads, cais qhov ntsuas los ntawm lub rooj ntev zaum vibrations tshwm sim los ntawm cov nyob ze compressors los yog xeem benches. Ib theem siab ntawm tus ntsuj plig tau lees paub qhov tseeb ntawm qib; cov taw yog kho nrog 5-mm hex key (muab).

Lub plawv ntawm qhov chaw nres tsheb yog qhov ntsuas qhov ntsuas qhov ntsuas ntsug, mounted ntawm qhov tseeb hauv av stainless hlau ncej uas taug kev hauv cov kab kab uas muaj tsawg dua 0.5 µm ntawm kev ua si. Lub tshuab caij nplooj ntoos hlav siv qhov tsis tu ncua 5 N ± 0.1 N tiv thaiv lub zog rau lub shim, tsis hais tus neeg teb xov tooj lub tes siab - tshem tawm 5-15 N variation ntawm tes tuav micrometers. Lub ntsej muag lub ntsej muag yog tungsten carbide disc nrog txoj kab uas hla ntawm 10 mm, lapped rau saum npoo ntawm Ra 0.1 µm, thiab radiused ntawm cov npoo los tiv thaiv indentation ntawm mos tooj dag shims. Lub anvil nqa tau txais thaum lub zog nias, tso cai nrawm nrawm thiab tshem tawm ntawm shims yam tsis muaj rub lub ntsej muag hla ib feem.

Kev ntsuas kev nyeem ntawv yog muab los ntawm qhov sib piv digital siab sib xyaw ua ke rau hauv qhov chaw nres tsheb kab, nrog kev daws teeb meem ntawm 0.001 hli (1 µm) tshaj li ntawm 0-20 mm. Comparator nta:

Hom tsis meej: Qhia qhov tseeb shim thickness ncaj qha, tsis muaj xoom-hloov yuam kev.

Hom kev kam rau siab: Tus neeg siv-txhais tau qhov txwv sab saud thiab qis; ib lub teeb liab LED flashes rau qhov tsis muaj qhov tshwj xeeb.

Kev txheeb cais hom: Captures txog 100 kev ntsuas thiab xam qhov nruab nrab, tus qauv sib txawv, thiab ntau yam - tsis muaj nuj nqis rau kev tswj xyuas cov khoom tsim khoom.

USB tso zis: Exports ntsuas cov ntaub ntawv mus rau lub PC rau cov ntaub ntawv los yog SPC software.

Cov zaub yog qaij-adjustable thiab backlit rau visibility nyob rau hauv tag nrho cov teeb pom kev zoo. Tus sib piv siv lub roj teeb CR2032 hloov tau (lub neej: 2,000 teev) lossis tuaj yeem siv tau los ntawm USB-C adapter nrog.

Qhov chaw nres tsheb no yog tsim los ntsuas tag nrho cov shims feem ntau ntsib hauv kev tsheb ciav hlau thiab chav tsev injector systems:

Injector pre-load shims6-18 hli OD, 0.5-3.0 hli thickness

Plunger chim shims8-12 hli OD, 0.1-1.0 hli thickness

Valve caij nplooj ntoos hlav washers10-25mm OD, 1.0-4.0mm thickness

Pump lub sij hawm shims15-30mm OD, 0.05-0.5 hli thickness

Nozzle retaining washer7-12 hli OD, 1.0-2.5 hli thickness

Qhov chaw nres tsheb qhib-thav duab tsim tso cai rau kev ntsuas ntawm ob qho tib si tiaj tus shims thiab me ntsis bowed Cheebtsam, raws li lub caij nplooj ntoos hlav-loaded anvil conforms rau qhov nruab nrab thickness nyob rau hauv lub cheeb tsam. Rau convex los yog concave shims, ib txheej ntawm peb lub pob zeb me me (2 hli, 4 hli, thiab 6 hli txoj kab uas hla) suav nrog, ua rau kev ntsuas ntawm qhov siab.

Q1: Vim li cas kuv thiaj tsis tuaj yeem siv kuv lub micrometer uas twb muaj lawm rau kev ntsuas shim?
A: Lub micrometer siv zog sib txawv nyob ntawm tus neeg teb xov tooj txoj kev xav - feem ntau 5-20 N - uas tuaj yeem ua rau cov mos mos ntawm 2-5 µm thiab deform nyias tooj dag shims mus tas li. Peb qhov chaw nres tsheb siv qhov ntsuas ntsuas, rov ua dua 5 N quab yuam, tshem tawm qhov yuam kev ntawm tus neeg teb xov tooj no. Tsis tas li ntawd, lub hauv paus granite muab cov ntaub ntawv tiaj tus tiag tiag, thaum lub micrometer's anvil thiab spindle yuav tsis zoo sib xws.

Q2: Lub shim kuv ntsuas yog me ntsis warped - qhov chaw nres tsheb ua li cas?
A: Lub caij nplooj ntoos hlav-loaded anvil nruab nrab lub thickness tshaj 10-mm txoj kab uas hla cheeb tsam. Rau cov shims loj heev (pom pom hneev), peb pom zoo kom siv lub me-inch anvil inserts (2 mm los yog 4 mm) los ntsuas lub ncov thickness, uas yog lub dimension uas cuam tshuam rau clamping quab yuam. Nco ntsoov sau ob qho tib si nruab nrab thiab tus nqi siab tshaj.

Q3: Kuv yuav paub li cas yog tias 5 N lub caij nplooj ntoos hlav quab yuam yog qhov tseeb?
A: Lub chaw nres tsheb suav nrog lub caij nplooj ntoo hlav me me uas ntsuas lub zog tiag tiag siv los ntawm lub dab teg. Cias tso lub adapter rau hauv qab lub dab teg thiab nias down - yog tias qhov ntsuas nyeem 5 N ± 0.2 N, lub caij nplooj ntoos hlav yog qhov tseeb. Yog hais tias tsis yog, kho lub caij nplooj ntoos hlav pre-load siv lub hex ntsia hlau muab.

Q4: Qhov chaw nres tsheb puas tuaj yeem ntsuas qhov tuab ntawm O-rings lossis cov ntsaws ruaj ruaj?
A: Tsis yog - mos elastomers yuav raug compressed los ntawm 5 N quab yuam, muab kev nyeem ntawv tsis zoo. Qhov chaw nres tsheb yog tsim los rau cov hlau tsis muaj zog shims thiab washers. Rau O-rings, peb pom zoo kom kho qhov muag lossis laser ntsuas qhov system.

Q5: Tus sib piv qhia qhov kev nyeem ntawv uas ntws los ntawm 1-2 µm tom qab ob peb ntsuas - yog vim li cas?
A: Qhov no feem ntau yog thermal drift - kev ua ntawm tuav lub shim hloov tshav kub los ntawm koj cov ntiv tes mus rau ib feem, nthuav nws los ntawm 1-2 µm. Txhawm rau tshem tawm qhov no, siv cov tweezers muab los tuav shims thiab tso cai rau lub shim kom sib npaug ntawm lub hauv paus granite rau 30 vib nas this ua ntej ntsuas. Tsis tas li ntawd, xyuas kom lub chaw nres tsheb tsis nyob hauv tshav ntuj ncaj qha lossis ze ntawm qhov chaw tshav kub.

Q6: Dab tsi yog qhov lav ntawm granite puag yog tias nws tau chipped?
A: Lub hauv paus granite yog them los ntawm kev tsim khoom tsis xws luag, tab sis kev sib tsoo ntawm qhov poob tsis tau them. Txhawm rau tiv thaiv lub hauv paus, peb pom zoo kom siv cov nylon tiv thaiv lev thaum lub sij hawm tuav nruj los yog thaum ntsuas qhov chaw nrog cov npoo ntse. Ib qho kev hloov granite slab yog muaj los ua ib qho khoom seem.

 

Txhawm rau ua kom koj qhov kev yuav khoom tau yooj yim thiab yooj yim, peb muab ntau yam kev xaiv them nyiaj ruaj ntseg:

Peb nyob ntawm no los ua kom koj cov txheej txheem xaj kev txhawj xeeb-dawb - xaiv txoj kev them nyiaj uas ua haujlwm zoo tshaj rau koj!
