3. Kugunda chiwerengero cha workpieces

 

Kwa chogwirira ntchito chomangika, kuchuluka kwa mabampu kumatha kugwiritsidwa ntchito kuti mudziwe malo omwe ali ndi zero pakupanga makina, ndipo kuchuluka kwa mabampu kumatha kukhala kwamagetsi kapena kumakina. Pali mitundu iwiri ya njira: nambala ya kugunda kwapakati ndi nambala ya kugunda kamodzi. Masitepe a nambala yogundana yapakati ndi awa:

 

Photoelectric static, makina liwiro 450 ~ 600rpm. Pamanja sunthani x-axis ya worktable kuti mutu womwe ukugunda ukhudze mbali imodzi ya chogwiriracho. Mutu wogunda ukangokhudza chogwirira ntchito ndipo kuwala kofiyira kuyatsa, ikani mtengo wolumikizana wa mfundoyi mpaka ziro. Kenako sunthani pamanja x-axis ya worktable kuti mutu womwe ukugunda ugwire mbali ina ya workpiece. Pamene kugundana mutu kungokhudza workpiece, lembani wachibale kugwirizana pa nthawi ino.

 

Malinga ndi mtengo wachibale kuchotsera awiri a kugunda mutu (ie kutalika kwa workpiece), fufuzani ngati utali wa workpiece chikugwirizana ndi zofunika zojambula.

 

Gawani nambala yogwirizanitsa iyi ndi 2, ndipo mtengo wake ndi mtengo wapakati wa x-axis ya workpiece. Kenako sunthani chogwirira ntchito pamtengo wapakatikati wa x-axis, ndikuyika mtengo wolumikizana wa X-axis mpaka ziro, womwe ndi malo a ziro a x-axis ya workpiece.

 

Lembani mosamalitsa mtengo wamakina wa zero pa x-axis ya workpiece mu imodzi mwa G54-G59, ndipo lolani chida cha makina chizindikire malo a ziro pa x-axis ya workpiece. Yang'anani kulondola kwa deta mosamala kachiwiri. Njira yokhazikitsira zero malo a Y-axis ya workpiece ndi yofanana ndi ya x-axis.

 

4. Konzani zida zonse molingana ndi malangizo ogwiritsira ntchito pulogalamu

 

Malinga ndi chidziwitso cha chida mu malangizo ogwiritsira ntchito pulogalamu, sinthani chida chomwe chikuyenera kukonzedwa, lolani chidacho chikhudze chipangizo choyezera kutalika chomwe chimayikidwa pa ndege yolozera, ndikuyika mtengo wachibale wa mfundoyi mpaka ziro pamene kuwala kofiira kwa kuyeza. chipangizo chayatsidwa. Magazini a Mold man timacheza bwino, oyenera kusamala! Sunthani chidacho pamalo otetezeka, sunthani chidacho pansi pa 50mm, ndikuyika mtengo wogwirizana wa mfundoyi kukhala ziro kachiwiri, komwe kuli zero malo a Z axis.

 

Lembani mtengo wamakina wa Z wa mfundoyi mu imodzi mwa G54-G59. Izi zimamaliza kuyimitsidwa kwa ziro kwa X, y ndi Z axs za workpiece. Yang'anani kulondola kwa deta mosamala kachiwiri.

 

Nambala yogundana ya mbali imodzi imakhudzanso mbali imodzi ya x-axis ndi Y-axis ya workpiece malinga ndi njira yomwe ili pamwambayi. Sinthani mtengo wachibale wa x-axis ndi Y-axis pamfundoyi mpaka utali wozungulira wa mutu wa nambala yogundana, womwe ndi malo a ziro a x-axis ndi y-axis. Pomaliza, lembani makina amakina a x-axis ndi Y-axis pa mfundo imodzi mwa G54-G59. Yang'anani kulondola kwa deta mosamala kachiwiri.
