Kodi Miyeso Yanu ya Ngodya Yakumanja Yasokonekera? Ulamuliro Wosagwedezeka wa Granite Square

Pofuna kupanga zinthu zopanda vuto lililonse, kuyang'ana mbali nthawi zambiri kumadalira umphumphu wa ubale wa angular ndi perpendicular. Ngakhale kuti pamwamba pa mbaleyo pamapereka maziko osalala, kuonetsetsa kuti mawonekedwe a workpiece ali olunjika bwino ku board imeneyo kumafuna chida chapadera komanso chokhazikika. Apa ndi pomwebwalo la granite,ndipo granite tri square yake yolondola kwambiri, imalimbitsa gawo lawo lofunika kwambiri mu labu ya metrology. Zida izi, pamodzi ndi zowonjezera zofunika monga maziko a granite a malo oimikapo gauge, zikuyimira chitsimikizo chachete chakuti miyeso ya angular imakwaniritsa zofunikira kwambiri.

Chifukwa Chake Granite Ikulamulira Zida Zowonetsera Zozungulira

Kusankha granite—makamaka diabase wakuda kwambiri—pa zida izi ndi nkhani yofunikira kwambiri. Mosiyana ndi mabwalo achitsulo kapena ma cast iron parallels, granite imapereka kuphatikiza kwapadera kwa zinthu zokhazikika zomwe zimapangitsa kuti ikhale chinthu chabwino kwambiri chotsimikizira kuwona kwa geometry:

• Kukhazikika kwa Dimensional: Granite ili ndi Coefficient of Thermal Expansion (CTE) yotsika kwambiri, zomwe zikutanthauza kuti kutentha pang'ono mkati mwa malo oyesera sikupangitsa kuti pakhale kusokonekera kwa geometric. Mosiyana ndi zimenezi, sikweya yachitsulo imatha kupindika pang'ono, zomwe zingasokoneze ngodya yofunika kwambiri ya madigiri 90.

• Kukana Kuvala Kosalimba: Zipangizo zoyezera kapena zogwirira ntchito zikamagwera pamwamba pa granite, zinthuzo zimawonongeka ndi kudulidwa pang'ono m'malo mosintha kapena kuphulika. Njira imeneyi imatsimikizira kuti m'mphepete kapena nkhope yofunikira imasunga kulondola kwake kwa nthawi yayitali.

• Kugwedezeka kwa Madzi: Kapangidwe ka kristalo wachilengedwe ndi kuchuluka kwa granite kumachepetsera kugwedezeka kwa chilengedwe. Izi ndizofunikira kwambiri pochita ma check a angular osavuta kwambiri, kuonetsetsa kuti muyesowo ndi wokhazikika komanso wodalirika.

Chitsimikizo cha sikweya ya granite chimatanthauza kuti chatsimikiziridwa kuti chili mkati mwa mainchesi ochepa a perpendicularity (squareness) kutalika kwake konse kogwirira ntchito, zomwe zimatsimikizira ntchito yake ngati chidziwitso cholondola cha kulinganiza zida zamakina ndi kuyang'anira zinthu.

Udindo ndi Ntchito ya Granite Tri Square

Ngakhale kuti sikweya yokhazikika ya granite nthawi zambiri imakhala ndi nkhope ziwiri zoyambira zopingasa, sikweya ya granite tri imapititsa patsogolo mawonekedwe olondola a angular. Chida chapaderachi chili ndi nkhope zinayi, zisanu, kapena zisanu ndi chimodzi zolondola zapansi zomwe zimapangidwa kuti zikhale za sikweya bwino kwa wina ndi mnzake. Kuzama kwa mawonekedwe kumeneku kumapangitsa kuti ikhale chida chabwino kwambiri chowunikira momwe makina amagwirira ntchito—monga malo opangira machining olunjika kapena ma CMM—komwe kuyang'ana kufanana ndi kupingasa pakati pa ma axes angapo ndikofunikira.

Kugwiritsa ntchito granite tri square kumalola mainjiniya kuchita macheke athunthu a makina omwe sikweya yosavuta singathe kuigwira. Mwachitsanzo, mu CMM configuration, tri-square ikhoza kuyikidwa pamwamba pa mbale kuti itsimikizire kuti Z-axis ndi yolunjika ku XY plane, ndikuyang'ana nthawi yomweyo kufanana kwa njira zoyima. Kulondola kwambiri komanso kukhazikika kwa tri-square kumateteza kukayikira kulikonse kokhudza muyezo wofotokozera, kupatula cholakwika chilichonse choyesedwa ku chida cha makina chokha m'malo mwa chipangizo chowunikira. Ikupezeka m'makulidwe osiyanasiyana, tri-square ndi yofunika kwambiri kuti ikwaniritse milingo yapamwamba kwambiri yolondola ya angular yomwe imafunidwa ndi mafakitale monga kupanga ndege ndi zida zamankhwala.

Kukhazikitsa Kuwerenga: Maziko a Granite a Ma Dial Gauge Stands

Kulondola kwa metrology sikungokhudza malo ofotokozera okha; komanso kukhudza kukhazikika kwa chida choyezera chokha. Maziko a granite a ma dial gauge ndi ma gauge a kutalika amagwira ntchito ngati cholumikizira chofunikira pakati pa chida chowerengera ndi mbale yayikulu pamwamba.

Bwanji kugwiritsa ntchito maziko a granite m'malo mwa achitsulo? Yankho lake lili mu kulemera ndi kukhazikika. Maziko akuluakulu a granite amapereka kulimba kwapamwamba komanso kufinya kwa chiyimidwe cha gauge, kuonetsetsa kuti mayendedwe a mphindi kapena kugwedezeka kwakunja sikubweretsa kusinthasintha kolakwika pa chizindikiro cha dial. Kuphatikiza apo, kusalala kwa mazikowo kumatsimikizira kuti mzati wa gauge umakhala wolunjika ku mbale ya pamwamba paulendo wake wonse. Izi ndizofunikira kwambiri poyerekeza miyeso, pomwe dial gauge iyenera kutsatira mawonekedwe patali, ndipo mwala uliwonse kapena kusakhazikika kwa maziko a giyayo kungayambitse cholakwika cha cosine kapena kupendekera mu kuwerenga. Kukhazikika komwe kumaperekedwa ndi maziko a granite omangidwa cholinga cha zida za dial gauge kumawonjezera kubwerezabwereza ndi chidaliro cha muyeso uliwonse womwe watengedwa.

Kuyika Ndalama mu Umphumphu wa Jiometri

Mtengo wa zida zowunikira granite izi, ngakhale kuti ndi zapamwamba kuposa zachitsulo, umasonyeza kuti zimayika ndalama zambiri pakupanga mawonekedwe abwino. Zidazi zimakhala ndi moyo wautali kwambiri, bola ngati zasungidwa bwino. Sizizizira, ndipo mawonekedwe awo abwino kwambiri amatanthauza kuti chitsimikizo chawo choyamba cholondola chimakhala choona kwa zaka zambiri, nthawi zambiri zaka makumi ambiri.

Mtengo weniweni woganizira ndi mtengo wa cholakwika. Kudalira sikweya yachitsulo yosatsimikizika kapena choyimilira chachitsulo chosakhazikika kungayambitse zolakwika za angular m'zigawo zopangidwa. Izi zimapangitsa kuti pakhale kukonzanso kokwera mtengo, kuwonjezereka kwa zinyalala, ndipo pamapeto pake, kutaya chidaliro cha makasitomala. Kuyika ndalama mu sikweya ya granite tri yovomerezeka kuti igwirizane ndi makina ndikugwiritsa ntchito maziko odalirika a granite pama sikweya a dial gauge kumachepetsa zoopsazi popereka malo ofunikira osadziwika bwino komanso okhazikika.

Mwachidule, sikweya ya granite ndi zida zake zoyezera zinthu sizinthu zowonjezera chabe; ndi miyezo yosakambirana yomwe imatsimikizira kukhazikika kwa njira yopangira. Ndiwo alonda chete olondola, kuonetsetsa kuti zinthu zomwe zikutuluka m'sitolo zikukwaniritsa zofunikira zenizeni za geometry zomwe makampani amakono amafunikira.
