Nei Granite Platform Ukobvu Ndiyo Kiyi Yekukwanisa Kutakura uye Sub-Micron Accuracy

Kana mainjiniya nenyanzvi dzemetro vachisarudza puratifomu yegranite chaiyo yekuyera nekugadzira zvinhu zvinoda simba, sarudzo yekupedzisira inowanzo tarisa pane chinhu chinoita sechiri nyore: ukobvu hwayo. Asi, ukobvu hweplate yepamusoro pegranite hausi chidimbu chakareruka - ndicho chinhu chikuru chinotungamira kugona kwayo mutoro, kuramba kuzununguka, uye pakupedzisira, kugona kwayo kuchengetedza kugadzikana kwenguva refu.

Pakushandisa zvinhu zvakanyatsorurama, ukobvu hwacho hahusarudzwi nemazvo; inyaya yekuongorora zvinhu zvakakosha zvichibva pamitemo yakatarwa uye misimboti yakasimba yekutsauka kwemuchina.

Mwero weUinjiniya Unotsigira Kusarudza Ukobvu

Chinangwa chikuru chepuratifomu yekunyatsorurama ndechekushanda senzvimbo yekutarisa yakati sandara zvakakwana, isingafambi. Nokudaro, ukobvu hwepuratifomu yepamusoro yegranite hunoverengerwa zvakanyanya kuve nechokwadi chekuti pasi pemutoro wayo wepamusoro unotarisirwa, kutsamira kwepuratifomu yese kunoramba kuri mukati megiredhi rayo rekutsungirira rakatarwa (semuenzaniso, Giredhi AA, A, kana B).

Dhizaini iyi yekuvaka inotevedzera nhungamiro dzeindasitiri, dzakadai seASME B89.3.7 standard. Nheyo huru pakusarudza ukobvu ndeyekuderedza kutsauka kana kukotama. Tinoverenga ukobvu hunodiwa nekufunga nezvehunhu hwegranite—kunyanya Young's Modulus of Elasticity yayo (chiyero chekuomarara)—pamwe chete nehukuru hweplate yacho uye mutoro unotarisirwa.

Mutemo weGunya reKukwanisa Kutakura Mutoro

Mwero weASME unogamuchirwa nevakawanda unobatanidza ukobvu zvakananga nekukwanisa kweplate kutakura mutoro uchishandisa mukana chaiwo wekuchengetedza:

Mutemo weKugadzikana: Puratifomu yegranite inofanira kunge yakakora zvakakwana kuti itsigire mutoro wese wenguva dzose unoiswa pakati peplate, pasina kutsausa plate iri padivi pe diagonal nehafu yekutsungirira kwayo kutsetseka.

Chinodiwa ichi chinoita kuti ukobvu huve hwakasimba hunodiwa kuti hutore huremu hwacho uku uchichengetedza kururama kwe sub-micron. Kune puratifomu yakakura kana kuti yakaremerwa zvakanyanya, ukobvu hunodiwa hunowedzera zvakanyanya kudzivirira nguva yekukotama yakakwira.

Ukobvu: Chinhu Chitatu Chinokosha Mukugadzikana Kwakarurama

Ukobvu hwepuratifomu hunoshanda semuchina wekusimudzira chimiro chayo. Puratifomu yakakora inopa mabhenefiti matatu makuru akabatana akakosha pakuenzanisa kwakarurama:

1. Kugona Kuwedzerwa Kwemutoro uye Kuchengetwa KweFlatness

Ukobvu hwakakosha pakudzivirira nguva yekukotama inokonzerwa nezvinhu zvinorema, zvakaita semichina mikuru yekuyera (CMMs) kana zvikamu zvinorema. Kusarudza ukobvu hunopfuura zvinodiwa zvishoma kunopa mukana wekuchengetedza unokosha. Izvi zvinhu zvinowedzera zvinopa puratifomu huremu hunodiwa uye chimiro chemukati kuti zvigovanise mutoro zvinobudirira, nokudaro zvichideredza zvikuru kutsauka kweplate uye kuve nechokwadi chekuti kutsetseka kwepamusoro kunodiwa kunochengetwa muhupenyu hwese hwepuratifomu.

2. Kuwedzera Kugadzikana Kwesimba uye Kuderedza Kudedera

Chidimbu chegranite chakakora uye chinorema chine huremu hwakakura, izvo zvinonyanya kukosha pakudzikamisa ruzha rwemakanika uye rweacoustic. Chikuva chikuru hachina frequency yechisikigo yakawanda, zvichiita kuti chisanyanya kukanganiswa nekuteterera kwekunze uye kudengenyeka kwenyika kunowanzoitika munzvimbo dzemaindasitiri. Kudzikisa uku kusingashande kwakakosha kune high-resolution optical inspection uye laser alignment systems uko kunyangwe kufamba kwe microscopic kunogona kukanganisa maitiro.

3. Kugadzirisa Kusagadzikana Kwekupisa

Kuwedzera kwehuwandu hwezvinhu kunononotsa kushanduka-shanduka kwetembiricha. Kunyange zvazvo granite yemhando yepamusoro ichitova nekuwedzera kwekupisa kwakaderera, ukobvu hwakakura hunopa thermal inertia yepamusoro. Izvi zvinodzivirira kushanduka kwekupisa nekukurumidza, kusina kufanana kunogona kuitika kana michina ichipisa kana mhepo inotonhodza, zvichiita kuti chimiro chepuratifomu chirambe chakafanana uye chakasimba kwenguva refu yekushanda.

Munyika yeinjiniya yekunyora nemazvo, ukobvu hwepuratifomu yegranite haisi chinhu chekudzikisa kuti uchengetedze mari, asi chinhu chikuru chekuvaka, zvichiita kuti chigadzirwa chako chiwane mhedzisiro inodzokororwa uye inoteverwa inodiwa nekugadzirwa kwemazuva ano.
