Dab tsi yog qhov ua rau deformation ntawm precision mechanical parts processing? Nyob rau hauv tus txheej txheem ntawm machining mechanical qhov chaw, ntxiv rau kom ntseeg tau qhov tseeb qhov tseeb thiab qhov chaw roughness, yuav tsum tau them nyiaj rau qhov deformation ntawm qhov chaw los ntawm sab nraud quab yuam. Txog cov neeg kho tshuab precision qhov chaw machining deformation, ua ntej ntawm tag nrho cov, peb yuav tsum to taub qhov ua rau ntawm qhov teeb meem no
Ua ntej, sab nraud quab yuam tshwm sim los ntawm deformation ntawm qhov chaw; cov laj thawj tuaj yeem muab faib ua ob pawg; ib qho yog nyob rau hauv cov txheej txheem ntawm machining precision mechanical qhov chaw, cov khoom yuav hloov cov kev taw qhia ntawm lub zog nyob rau hauv lub zog ntawm txiav quab yuam; yog vim li cas rau qhov kev hloov no yog qhov tsis muaj rigidity ntawm cov khoom lawv tus kheej. Ib feem yuav deformed nyob rau hauv lub zog ntawm lub zog. Lub deformation feem ntau pom tseeb. Thaum nyem los ntawm lub zog, ib feem yuav protrude ho nyob rau hauv cov kev taw qhia ntawm lub zog, uas ua rau deformation loj, tsis muaj peev xwm mus nqa tawm cov kauj ruam tom ntej, ib feem yuav tsis ncav cuag lub hom phiaj raws li nws yuav tsum tau, thiab ua substandard khoom.
Thib ob, riam txiav txheej txheem tsim los ntawm tshav kub deformation; nyob rau hauv cov txheej txheem ntawm precision qhov chaw ua, cov hniav thiab cov dawb paug yuav muaj kev kub ntxhov ntawm qhov chaw, qhov chaw tiv tauj yuav inevitably tsim kub. Yog tias tsis siv cov txheej txheem txias kom tsim nyog, ua ke nrog qhov sib txawv ntawm cov cuab yeej cua sov dissipation, nce hnav, ua ke nrog cov khoom siv cua sov tsis zoo thiab qhov kub siab ntawm qhov chaw sib cuag, deformation yuav tshwm sim thaum lub sij hawm ua tiav ntawm precision mechanical qhov chaw, kom cov khoom tsis tuaj yeem ncav cuag qhov xav tau.
Thib peb, qhov chaw ua haujlwm hauv qhov clamping tshwm sim los ntawm deformation; cov khoom yuav tsum tau clamped ua ntej ua, uas kuj yog ib qho tseem ceeb ntawm cov khoom deformation. Thaum clamping qhov chaw, koj yuav tsum xaiv qhov tsim nyog clamping point thiab clamping quab yuam. Tus naj npawb ntawm cov ntsiab lus clamping thiab cov ntsiab lus txhawb nqa ntawm qhov yuav tsum yog tib yam. Yog tias muaj ntau lub ntsiab lus clamping ntawm ib feem, kev saib xyuas yuav tsum tau them rau qhov clamping ntu thiab lub zog clamping. Machining kuj nyuaj yog tias tsis ua kom zoo. Nws yog ib qho yooj yim rau deform.
