Nau'i da ka'idoji don amfani da ma'aunin kaurin fenti

Lokacin siyan motar da aka yi amfani da ita, zai iya zama da wahala ga mai siye ya tantance yanayinta daidai. Bayan kyawawan kayan nade na iya ɓoye lahani da lalacewa sakamakon haɗari, wanda mai siyarwa na iya yin shiru game da shi. Na'ura ta musamman - ma'aunin kauri - zai taimaka wajen bayyanar da yaudara, tantance ainihin yanayin jiki da gano kaurin aikin fentin sa.

Menene ma'aunin kauri

An auna kaurin fentin (fentin fentin) a cikin microns (1 microns = 000 mm.). Don kyakkyawar fahimtar waɗannan adadi, yi tunanin gashin mutum. Matsakaicin kaurinsa microns 1 ne, kuma kaurin takardar A40 shine micron 4.

Ma'aunin kauri yana auna nisa daga karfe zuwa ma'auni ta amfani da lantarki ko igiyar ruwa. Na'urar tana gano tsawon zango kuma tana nuna sakamakon akan nuni.

Sabili da haka, yana yiwuwa a ƙayyade abubuwan da aka sake fenti da ɓangaren putty bayan gyarawa, da sanin kaurin fentin wani samfurin. Matsakaicin ƙimar motocin zamani yana cikin kewayon micron 90-160. An ba da izinin kuskure a wurare daban-daban na jiki ta hanyar 30-40 micron, kuskuren na'urar kanta ita ma ya kamata a la'akari da ita.

Nau'in na'urorin

Akwai adadi mai yawa na nau'ikan ma'aunin kauri. Akwai samfuran daban don auna kaurin kankare, takarda, tubulawan birgima ko zanen gado. Ana amfani da manyan nau'ikan guda huɗu don auna aikin zane-zane:

• magnetic;
• lantarki;
• duban dan tayi;
• Eddy halin yanzu.

Magnetic

Irin waɗannan na'urori suna da zane mafi sauki. Akwai maganadisu a cikin karamin lamari. Dogaro da kaurin murfin, ƙarfin jan maganadisu zai canza. Sakamakon da aka samo an canja shi zuwa kibiyar, wanda ke nuna ƙimar a cikin ƙananan ƙwayoyin cuta.

Gages masu kaurin Magnetic ba su da tsada, amma sun fi ƙasa da daidaito a ma'auni. Yana nuna ƙimomin ƙima kawai kuma yana aiki kawai tare da saman ƙarfe. Kudin na'urar zai iya farawa daga 400 rubles.

Electromagnetic

Girman ma'aunin electromagnetic yana aiki daidai da hanyar ma'aunin kaurin magnetic, amma yana amfani da shigar da lantarki don ma'aunai. Daidaitawar waɗannan mitoci sun fi girma, kuma farashin ya zama karɓaɓɓe sosai, kusan dubu 3 rubles. Saboda haka, waɗannan na'urori sun fi yawa tsakanin masu motoci. Babban rashin dacewar su shine kawai zasu iya aiki da saman karfe. Ba su auna murfin a kan sassan aluminum ko jan ƙarfe ba.

Ultrasonic

Ka'idar aiki na wadannan kauri gages dogara ne a kan aunawa da saurin wucewa na ultrasonic taguwar ruwa daga farfajiya zuwa firikwensin. Kamar yadda kuka sani, duban dan tayi ta cikin abubuwa daban-daban ta hanyoyi daban-daban, amma wannan shine asalin samun bayanai. Suna da yawa saboda suna iya auna kaurin fenti akan wurare daban-daban, gami da filastik, yumbu, kumshe da ƙarfe. Saboda haka, ana amfani da irin waɗannan na'urori a tashoshin sabis na ƙwararru. Rashin amfani da sikanin kauri na ultrasonic shine tsada mai tsada. A matsakaici, daga 10 dubu rubles da ƙari.

Eddy na yanzu

Wannan nau'in ma'aunin kaurin yana da mafi girman ma'aunin ma'auni. Ana iya aiwatar da awo LKP akan kowane ƙarfe, da kan ƙarfe marasa ƙarfe (aluminium, jan ƙarfe). Cikakken gaskiya zai dogara ne akan yanayin sarrafawar abu. Ana amfani da murfin EM, wanda ke haifar da magnetic magnetic filayen saman ƙarfe. A kimiyyar lissafi, ana kiran wannan Foucault currents. Sananne ne cewa jan ƙarfe da aluminium suna aiki da kyau a halin yanzu, wanda ke nufin cewa waɗannan ɗakunan zasu sami ingantattun karatu. Za a sami kuskure a kan kayan aikin, wani lokacin mahimmanci. Na'urar cikakke ce don auna a jikin jikin aluminum. Matsakaicin farashi yakai dubu dubu 5 da ƙari.

Calibrating kayan aiki

Dole ne a daidaita kayan aikin kafin amfani. Wannan abu ne mai sauki. Tare da na'urar, saitin ya haɗa da faranti da aka yi da ƙarfe da filastik. Kayan aikin galibi yana da maɓallin "cal" (calibration). Bayan ka danna madannin, kana bukatar hada abin firikwensin ma'aunin kaurin a farantin karfe ka sake saita shi zuwa sifili. Sannan sai mu sanya roba a plate din karfe mu sake auna ta. An riga an rubuta kaurin farantin filastik a kai. Misali, microns 120. Ya rage kawai don bincika sakamakon.

An ba da izinin ƙananan ɓata 'yan ƙananan microns, amma wannan yana cikin kewayon al'ada. Idan na'urar ta nuna daidai darajar, to zaku iya fara aunawa.

Yadda ake amfani da ma'aunin kauri

Gano kaurin masana'antar fentin mota kafin aunawa. Akwai teburin bayanai da yawa akan Intanet. Yakamata a fara awo daga gefen gaba, a hankali yana tafiya tare da kewayewar jiki. Carefullyari a hankali bincika wuraren da ke da tasirin tasiri: fenders, ƙofofi, sills. Aiwatar da firikwensin zuwa yanayin tsabtace jiki.

Karatu a sama 300 µm yana nuna kasancewar filler da sake shafawa. Micron 1-000 suna nuna manyan lahani a cikin wannan yanki. An daidaita farfajiyar, an saka shi da zane. Motar tana iya kasancewa cikin haɗarin gaske. Bayan wani lokaci, fasa da kwakwalwan kwamfuta na iya bayyana a wannan wurin, kuma lalata zai fara. Ta hanyar gano irin waɗannan yankuna, ana iya tantance ɓarnar da ta gabata.

Wannan ba yana nufin cewa mota mai gyaran fentin fenti baya bukatar siye ba. Misali, karatu a sama 200 µm galibi yana nuna cire ƙwanƙwasa da ƙananan kwakwalwan kwamfuta. Wannan ba mahimmanci bane, amma yana iya rage farashin. Akwai damar ciniki.

Idan masu alamomin sun fi na masana'antar mahimmanci, to wannan yana nuna cewa maigidan ya wuce shi da gogewar abrasive yayin cire scratches. Na cire wani zanen fenti wanda yayi kauri sosai.

Hakanan kuna buƙatar fahimtar wane nau'in na'ura kuke da shi a hannunku. Girman ma'aunin electromagnetic baya aiki akan filastik. Ba zai yi aiki don auna fentin fentin a kan damben ba. Kuna buƙatar na'urar ultrasonic. Hakanan kuna buƙatar sanin idan akwai sassan aluminum a cikin jiki.

Ba lallai bane ku sayi sabon kayan aiki idan baku amfani dashi sau da yawa. Za'a iya yin hayar ma'aunin kauri don kuɗi.

Ma'aunin kauri yana baka damar tantance yanayin fentin jikin motar. Daban-daban na kayan aiki suna da daidaito da dama daban-daban. Don bukatun kansu, lantarki yana da dacewa sosai. Idan kuna buƙatar cikakken binciken jiki, to yakamata ku tuntubi ƙwararrun.
