Nyob rau hauv tus txheej txheem ntawm tapping workpieces nyob rau hauv lub machining kev lag luam, tej zaum vim tsis tsim nyog technology (qhov kawg lub ntsej muag ntawm threaded lub qhov yog ua tiav tom qab vuam lub workpiece nrog cov txheej txheem threaded qhov), cov neeg ua hauj lwm ua yuam kev nyob rau hauv kev nyeem cov drawings (tsis ncaj ncees lawm loj) los yog Kev ua haujlwm yuam kev (Xa yuam kev, drilling qhov ntiav hauv qab, kev ua haujlwm yuam kev, thiab drilling thiab tapping threaded qhov tob qhov chaw yuam kev) thiab ntau lwm yam ua rau qhov tshwm sim uas cov threaded qhov ntawm qee qhov workpieces tsis tob txaus tom qab ua tiav.
Thaum qhov teeb meem zoo li no tshwm sim, vim tsis muaj kev ruaj ntseg ntawm lub tshuab drilling, cov neeg ua haujlwm thiab cov kws tshaj lij feem ntau ncaj qha nruab qhov chaw ua haujlwm nrog lub qhov threaded yuav tsum tau kho ntawm lub tshuab tho txawv los yog milling tshuab workbench, thiab siv cov threaded qhov hauv qab qhov laum raws li. mus rau qhov kho thiab fastening. Tom qab lub puab txoj kab uas hla ntawm lub threaded qhov yog calibrated, laum lub hauv qab qhov rau qhov tob ntawm tus qauv, thiab ces kho nws nrog ib tug kais. Txawm li cas los xij, txoj kev no yooj yim ua rau tus neeg teb xov tooj "frictionally txiav" cov xov qub thaum lub sij hawm tus txheej txheem ntawm qhov tob hauv qab lub qhov, ua rau muaj kev puas tsuaj rau cov xov uas twb muaj lawm thiab cuam tshuam rau kev ua haujlwm zoo ntawm lub qhov threaded.
Nyob rau tib lub sijhawm, txoj kev kho no xav kom tus neeg teb xov tooj muaj cov txheej txheem zoo, thiab nws yuav siv sij hawm ntev los kho qhov threaded qhov, thiab kev ua hauj lwm efficiency tsawg heev. Tus nqi ntawm kev kho nws nrog tho txawv thiab milling cov cuab yeej kuj yog qhov siab. Tsis tas li ntawd, yog tias lub ntsej muag kawg ntawm lub qhov threaded tsis yog perpendicular mus rau hauv nruab nrab kab ntawm lub threaded qhov vim reprocessing tom qab vuam los yog lwm yam yog vim li cas, nws yuav inevitably ua rau kev puas tsuaj rau cov uas twb muaj lawm xov thaum lub sij hawm thib ob drilling ntawm threaded hauv qab qhov. , uas yuav inevitably ua rau lub zais txaus ntshai ntawm scrapping los yog downgrading lub threaded qhov ntawm lub workpiece. Tom qab ntau qhov kev sib tham thiab kev sim, tus kws sau ntawv tau pom cov kev ua kom yuam kev nrog kev ua haujlwm sai dua thiab txhim khu kev qha thiab ruaj khov.
1. Cov txheej txheem ntawm kev kho qhov ntiav threaded qhov ntawm lub tshuab radial drilling
Yog hais tias lub hardness ntawm cov ntaub ntawv workpiece yog siab, nws yuav tsum tau drilled thiab tapped ntawm lub radial drilling tshuab thaum kho nws threaded qhov. Txawm li cas los xij, nws yog ib qho tsim nyog yuav tsum tau kho qhov nruab nrab ntawm lub qhov sib npaug mus rau qhov chaw nruab nrab ntawm qhov ntxaiv ntawm lub tshuab drilling raws li qhia hauv daim duab 1, thiab tom qab ntawd ncaj qha siv lub laum me ntsis los kho qhov threaded qhov thiab qhov nruab nrab ntawm lub laum ncej. lub tshuab drilling yuav tsum tau coaxial, thiab siv lub laum me ntsis thiab coj mus rhaub raws li qhov yuav tsum tau ua. Laum thiab kais ntiav threaded qhov.
Cov kauj ruam rau kev kho qhov threaded qhov: ua ntej, tso lub workpiece ntawm lub adjustable ntsia hlau uas tau teem rau ntawm lub rooj tshuab drilling; Thib ob, ntsia hlau kho cov ntsia hlau rau hauv lub qhov threaded yuav tsum tau kho thiab nruj kom paub meej tias cov kab nruab nrab ntawm cov ntsia hlau kho yog zoo ib yam nrog cov kab nruab nrab ntawm qhov threaded qhov zoo ib yam; Tom qab ntawd, muab lub ntxaiv ntawm lub tshuab drilling ze rau ntawm lub calibration ntsia hlau (ib qhov sib txawv yuav tsum tau sab laug kom tsis txhob muaj qhov ntxaiv ntawm lub tshuab drilling los ntawm nias lub calibration ntsia hlau thiab cuam tshuam rau qhov tseeb calibration), thiab kho cov ntsia hlau adjustable los ua cov ntsia hlau calibration. parallel mus rau lub ntxaiv ntawm lub tshuab drilling, maj mam kho thiab kaw kom ntseeg tau tias qhov kev ua tsis zoo ntawm qhov sib npaug tsis siab tshaj 0.03mm, ib daim ntawv tuaj yeem siv los rub lub sab sauv thiab qis ntawm lub ntsiab ncej ntawm lub tshuab drilling thiab cov ntsia hlau calibration kom nws sib npaug; Thaum kawg, ntxig lub laum chuck Nruab nws nyob rau hauv lub spindle ntawm lub tshuab drilling, clamp lub hloov kho laum nyob rau hauv lub laum chuck, ntxig lub laum me ntsis rau hauv lub threaded qhov yuav tsum tau kho, saib xyuas tias qhov sib txawv ntawm lub shank thiab threaded qhov yog. uniform, thiab xyaum raws li qhov yuav tsum tau ua kom tiav qhov xyaum. Tom qab lub qhov yog hloov nrog ib tug kais ntsia hlau.
Lub chaw tsim khoom ntawm kev hloov kho laum me ntsis yog qhov yooj yim heev, tsuas yog zom cov laum ntug ntev ntawm qhov qub laum me ntsis kom ntev txaus. Qhov ncaj shank yog sib npaug hauv av los yog muab tua los ntawm 1 hli, kom muaj qhov sib txawv ntawm 1 hli ntawm lub qhov drilled thiab lub qhov qub threaded, thiab tsis muaj kev puas tsuaj rau cov xov uas twb muaj lawm ntawm threaded qhov yuav tshwm sim.
Qhov kev xav tau ntawm cov ntsia hlau calibration yog siab, thiab qhov threaded yuav tsum yog coaxial nrog cov ncaj tuav ib feem tsis muaj dabtsi yog khoov, thiab nws qhov ntev yog feem ntau 3 mus rau 5 npaug ntawm qhov tob ntawm cov xov yuav tsum tau kho kom paub tseeb tias qhov tseeb calibration.
Qhov thib ob, txoj kev kho cov qhov ntiav ntiav nrog rab yaj phom laum
Rau cov khoom ua haujlwm nrog cov ntim loj, hnyav hnyav thiab cov khoom muag (xws li aluminium alloy workpieces), thaum nws tsim nyog los kho qhov teeb meem ntawm qhov tob tob ntawm threaded qhov nrog me me diameters, koj tuaj yeem siv rab yaj phom laum los tuav cov lus hais txog kev hloov kho laum. thiab ncaj qha laum lawv, thiab tom qab ntawd manually coj mus rhaub cov xov (saib daim duab 2).
duab
3. Cov lus xaus
Txoj kev kho me me threaded qhov yog qhov tshiab heev, tshwj xeeb tshaj yog siv cov laum qub thiab hloov kho cov khoom siv tom qab sib tsoo. Qhov teeb meem. Hauv cov txheej txheem tsim khoom tiag tiag, qhov teeb meem ntawm kev kho qhov ntiav ntiav cov qhov taub tuaj yeem daws tau zoo, thiab cov txheej txheem yog qhov yooj yim, siv tau, thiab tuaj yeem nrov.
