Tsis zoo siv
Adding a fourth axis to a CNC machine tool requires compatibility with seven core components: drive, system, motor, and machine body. Cov ntsiab lus tseem ceeb yog tias cov kev qhia tshwj xeeb ntawm txhua qhov sib tw sib xyaw ua ke, lawv qhov kev ua haujlwm yog sib koom tes, thiab lawv tau raws li lub tshuab cuab tam thauj khoom thiab tshuab xav tau.
Cov Txheej Txheem Ua Lag Luam Tau Yuav Tsum Tau Ua
1. Tsav tsheb tsav
Chav tsav yuav tsum tau sib xws nrog lub tshuab cuab tam tus qauv tsav tsheb uas twb muaj lawm. Mitsubishi M60 series siv lub npav sib txuas lus, thaum M70V thiab M80 Series Siv Kev Sib Txuas Lus Fiber Option Drive. Drives los ntawm txawv series tsis sib pauv tau.
Lub tsev tsav tsheb yuav tsum muaj qhov tshwj xeeb plaub - Axis tswj interface. Thaum lub sij hawm installation, nws yuav tsum tau kho nyob rau hauv qhov chaw tsim nyog nyob rau hauv cov txee hluav taws xob, ua kom muaj qhov chaw txaus rau tshav kub dissipation, thiab lub hwj chim thiab cov lus tawm suab yuav tsum muaj kev sib txuas.
2. CNC system
Lub kaw lus yuav tsum muaj plaub - ax axis tswj ua haujlwm. Piv txwv li, Mitsubishi M70V thiab M80 series machine tau ua - hauv 4-axis tus qauv ua haujlwm, yuav tsum tsis muaj kev ua haujlwm ntxiv.
Cov kab kos ntaiv yuav tsum muaj qhov thib plaub qhov - Axis Siv Hloov thiab Axis xaiv cov cim. Yog tias cov haujlwm no ploj lawm, hu rau cov chaw tsim khoom siv rau kev hloov kho tshiab. Parameter chaw yuav tsum muaj kev faib cov lej tswj hwm (teeb tsa rau 4), axis npe, thiab lwm yam khoom tseem ceeb.
3. Tsav (servo lub cev muaj zog)
Lub cev muaj zog yuav tsum tsim nyog rau kev ua haujlwm machining. Rau siab - precision, siab- ceev scenarios, xaiv lub cev muaj zog piston; rau nruab nrab {3} bead, nruab nrab {{{}} ceev scenarios, xaiv lub cev muaj zog ceev; Rau hnyav - ntim, qis - ceev scenarios, xaiv lub iav tsav.
Lub cev muaj zog yuav tsum phim tus tsav tsheb. Piv txwv li, M80 system tuaj yeem ua khub nrog HF104S- A48 servo lub cev muaj zog. Iav Backlash yuav tsum tau hloov kho tsis pub dhau 0.02 hli kom tsis txhob muaj suab nrov tsis meej.
5. Lub cev tseem ceeb (cov lus teb)
Cov qauv siv tshuab yuav tsum muaj cov khoom siv tseem ceeb xws li rooj ntxaiv, cab cab, thiab nres sib dhos. Lub kaw lus braking tuaj yeem yog ib lub tiaj tus nres lossis lub nplhaib nres.
Lub nra yuav tsum tau raws li kev tsim qauv. Ntsug thiab kab rov tav load yuav tsum tsis txhob tshaj qhov tshwj xeeb hauv phau ntawv. Plaub {-}}}} Nrhiav pob cov kabmob yog nyiam rau cov kabmob swing kom ntseeg tau tias qhov ua yuam kev zoo <0.01 hli.
Ib 1.5-2.0s ncua kev xauv / xauv yuav tsum tau tso cai thaum lub teeb tsa kom tiv thaiv nres nres. Yog qhov ntsuas hluav taws xob yog qhov tseem ceeb yog qhov tseem ceeb.
6. Chaw nres tsheb hydraulic
Lub kaw lus siab yuav tsum tau sib piv rau lub nra torque. Ib qho 10 {- 16mpa {3} {{{{{{{{}} {}} Lub hydraulic siv los yuav tsum tau tswj ntawm 20kg / cm². Cov roj tank muaj peev xwm yuav tsum yog 3-5 zaug nrog lub lim dej ntws, nruab nrog lim uas tsim nyog (5-10μm rau kev ntsuas siab). Yuav tsum muaj cov khoom lag luam uas yuav tsum muaj rau cov nra hnyav lossis hnyav dua.
Lub voj tswj yuav tsum muaj cov khoom sib xws xws li hluav taws xob hloov pauv li cas thiab txeej li cas los xyuas kom cov lus teb sai, thiab txo qis rov qab cuam tshuam.
6. Neeg tsim tus kav
Tus qauv txuam nrog qhov precision ntawm plaub axis yuav tsum raug xaiv. Thaum txoj kev ua yuam kev yog<0.02mm, the grating ruler resolution must be compatible with that precision level.
Qhov chaw teeb tsa yuav tsum zam kev paug los ntawm kev siv cov kua thiab cov teeb meem kaw teeb liab nrog cov lus qhia cnc, txhim kho kev ua kom raug.
7. Lub cev muaj zog encoder
Yuav tsum sib haum nrog tus qauv servo lub cev muaj zog, koom nrog hauv kev kaw {{leto} lub voj ceev cov lus qhia kom ua tiav qhov tseeb ntawm ± 1%.
Cov xaim yuav tsum muaj kev sib txuas tau kom raug rau cov lus qhia ntawm cov lus qhia, ua haujlwm nrog kev tsim nyom nrog cov ntaub ntawv sib luag los muab cov ntaub ntawv tiag tiag thiab cov ntaub ntawv ceev rau cov kab ke, ua kom pom cov ntaub ntawv ceev.
Lub ntsiab
Cov ntsiab lus tseem ceeb rau kev ntxiv plaub axis rau lub tshuab CNC tshuab yog "qhov kev qhia tshwj xeeb, kev ua haujlwm ruaj khov, thiab kev ua haujlwm ruaj khov" ntawm xya lub chaw loj. Tus tsav thiab lub kaw lus yuav tsum ua kom muaj teeb liab kev xa tawm, lub cev yuav tsum muaj zog ruaj khov thiab kev hloov kho cov kab ke hydraulic, thiab cov dav hlau ua kom kaw lub zog Txhua qhov kev sib xyaw ntawm kev sib ntsib ntawm cov kev ua tau zoo thaum tseem tab tom ua kom tau ua tiav tsim kom tiav.
