Kev tshawb nrhiav ntawm Slider Pair of Dov Qhia Phau Ntawv Cav Tov Hauv Machining Center
Daim ntawv ntxeev muaj qhov zoo ntawm kev coj ncaj tshaj, kev ua haujlwm zoo, kev rigidity thiab kev nplua tus txhuam kev sib luag, thiab dav siv rau hauv machining center tshuab cuab yeej. Los ntawm kev kawm txog txoj kev loj hlob thiab cov cwj pwm ntawm cov kev taw qhia, nws muab lub tswv yim theem rau cov tub ntxhais kawm ntawv qib siab vocational schools los kawm cov qauv kawm CNC tshuab cov cuab yeej, txhawb cov ntsiab lus ntawm cov kev kawm, thiab tsim kom muaj lub hauv paus rau kev tsim kho high-precision pub mechanisms. Los ntawm qhov kev qhia ntawm lub neej ntawm kev qhia txog kev ywj pheej los ntawm thawj theem pub, ntau ntau yam uas cuam tshuam txog lub neej ntawm kev taw qhia kev tsheb nqaj hlau yog soj ntsuam thiab soj ntsuam, thiab cov ntaub ntawv siv rau kev tshawb nrhiav yav tom ntej ntawm daim ntawv ntxeev.
Kev txhim kho ntawm daim ntawv qhia kev khawb ntawm qhov chaw machining tau muab faib ua plaub theem. Tus thawj theem pib pom cov yam ntxwv zoo ntawm daim ntawv qhia kev ywj pheej thiab kev kho tau thiab khi tau cov lus taw qhia tawm ncaj qha. Nyob rau theem ob, vim muaj kev tshiab rau nws txoj kev siv thiab kev siv, neeg pib kawm txoj kev siv txoj hlua khi, daim ntawv qhia kev khau uas tsis ntub pob. Hauv peb theem, daim ntawv thov ntawm daim ntawv qhia kev rolling nyob rau hauv cov lus teb ceev ceev tshaj 35 m / min yog maj ntxiv. Thaum cov lus tsa suab siab ceev yog reciprocating, txoj kev sib tsoo thiab kev sib tsoo ntawm cov khoom raug tshem tawm, thiab tsis tshua muaj suab nrov. Nyob hauv plaub theem, vim yog daim ntawv thov ceev ceev ntawm daim ntawv ntxeev ntawm qhov kev siv phom loj, high-precision, high-speed machining chaw cuab yeej cuab tam, lub rigidity thiab bearing peev pob ntawm lub cev ua haujlwm tsis txaus siab, thiab cov tub lag luam hom kev hnyav hnyav qhia txog kev tsheb nqaj hlau. Nws inherits qhov zoo ntawm cov qub thiab tiag tiag raws li qhov yuav tsum tau ntawm lub chaw machining machine tshuab nkawm.
Lub tshuab ua haujlwm machining muaj kev cai ntau dua rau ntawm daim ntawv ntxaws. Ua ntej, cov lus qhia tseem ceeb zoo dua. Tus qauv geometrical ntawm daim ntawv qhia kev ywj pheej ncaj qha cuam tshuam rau cov lus qhia kev ncaj ncees ntawm cov khoom seem. Vim li no, hauv qhov kev ntsuas xyuas uas tau teev los ntawm daim ntawv qhia yob, qhov ncaj qha ntawm daim ntawv qhia kev tsheb nqaj hlau thiab qhov sib npaug ntawm qhov sib txuas ntawm ob txoj kev taw qhia yog ob qho Muaj cov cai tswj meej. Ib qho ntawm lub ntsiab tseem ceeb uas cuam tshuam rau qhov tseeb yog kev tsim kev txuam, kev sib txuam zoo ntawm phau ntawv qhia, thiab lub rigidity thiab deformation ntawm daim ntawv ntxeev thiab nws txoj kev txhawb nqa.
Qhov thib ob, txoj kev coj ntawm txoj kev sib tw ntawm txoj kev tsav tsheb yog qhov zoo, thiab lub sij hawm ntev ntawm kev txav mus rau ntawm qhov chaw tsheb npav raws li qhov chaw nres tsheb npav yuav ua rau tsis sib npaug ntawm daim ntawv qhia txoj hlua, hla rhuav tshem cov lus tsa suab ntawm cov lus qhia tsheb nqaj hlau kom txog rau thaum lub sij hawm xyaw machining. Cov coj hnyav ntawm txoj kev ywj pheej ncaj qha cuam tshuam rau kev ua haujlwm ntawm kev siv tshuab. Kev hnav kev hnyav ntawm daim ntawv qhia kev ywj pheej yog tus yuam sij rau tus tsim thiab kev tsim khoom. Nws tseem yog ib qho tseem ceeb rau kev ntsuas qhov zoo ntawm lub chaw ua haujlwm. Nws pab txoj kev hnav ris tsho ntawm kev qhia ntawm qhov chaw ua haujlwm. Nws tseem ceeb heev uas cov hlua me me hnav tsis raug thiab tsis pub rho nyiaj los yog hloov kho tom qab tsis ua haujlwm.
Lub rigidity ntawm re-machining center dov qhia yog zoo dua. Daim ntawv qhia rov qab yuav muab deformed tom qab raug quab yuam sab nraud, uas yuav cuam tshuam rau qhov chaw txheeb ze nruab nrab ntawm cov khoom seem thiab cov kev taw qhia meej ntawm qhov seem. Yog li, qhov chaw ua haujlwm machining center yuav tsum tau muaj kev zoo rigidity. Tus deformation ntawm daim ntawv qhia kev khawb ntawm qhov chaw machining yog nyob ntawm daim ntawv ntawm daim ntawv qhia txog kev ywj pheej, qhov loj ntawm daim ntawv qhia txog kev ywj pheej thiab kev sib txuas hom thiab quab yuam ntawm daim ntawv qhia rov qab nrog kev txhawb nqa.
Thaum kawg, txoj kev sib txhuam ntawm cov ntawv qhia kev sib xyaw kom haum yog zoo heev, lub txav uas yooj yim nkag mus thaum tsiv ntawm qhov qis qis, thiab qhov nkag thaum pub mov zog yuav ua rau lub roughness ntawm qhov chaw ua haujlwm, thiab qhov nkag thaum lub caij kev txav yuav txo qhov tseeb qhov tseeb. Yog li, nws yuav tsum tau hais tias daim ntawv qhia ntawm lub chaw ua haujlwm yuav tsum khov kho thaum qeeb. Tsis tas li ntawd, kev txhuam coefficient ntawm daim ntawv ntxeev yog me me los txo qhov kev tsis sib haum xeeb thiab lub thermal deformation ntawm qhov qhia txog nws tus kheej.
Daim ntawv qhia ntawm qhov chaw ua haujlwm yog tsim los ntawm ib daim ntawv qhia kev thaiv thiab ib daim ntawv qhia tawm ncaj qha. Daim ntawv qhia kev thaiv ntawm chaw ua haujlwm feem ntau yog siv ib tug cuaj hlau cylindrical circulating, uas koom tes nrog txoj kev tsheb nqaj hlau ntawm lub tshuab txaj, thiab muaj qhov kom zoo dua tias nws tsis txwv los ntawm txoj kev stroke ntev. Lub rigidity yog tus loj.
