Na'urar honing wata na'ura ce da ake amfani da ita don yin ingantattun mashin ɗin saman saman ciki. Babban aikinsa ya ta'allaka ne a cikin daidaitaccen aiki na honing head da daidaitaccen daidaita sashin. Kwarewar aikin sassan injin honing ba kawai inganta daidaiton injin ba amma kuma yana haɓaka rayuwar kayan aiki. Abubuwan da ke biyowa sun ba da cikakken bayani kan hanyoyin aiki da matakan kariya ga manyan sassan injin honing.
I. Shigarwa da Gyaran Shugaban Honing
Shugaban honing shine ainihin bangaren injin honing kuma kai tsaye yana shafar ingancin injin. A lokacin shigarwa, tabbatar da cewa honing shugaban yana amintacce an haɗa shi da sandal kuma zaɓi dutsen honing da ya dace dangane da diamita na workpiece. Lokacin daidaitawa, kula da abubuwa masu zuwa:
Sarrafa Tashin Jiki na Dutse: Ta hanyar daidaita tsarin bazara ko na'ura mai aiki da karfin ruwa a kan honing, kula da matsa lamba mai dacewa tsakanin dutsen honing da bangon bangon aikin. Guji sako-sako da ya wuce kima (sakamakon injin da bai cika ba) ko matsewa da yawa (sakamakon lalacewa).
Daidaita Kai: Tabbatar cewa shugaban honing ya daidaita tare da layin tsakiya na workpiece. Rashin yin hakan na iya haifar da karkacewar diamita ko rashin daidaituwar saman. Ana iya yin gyare-gyare ta hanyar amfani da ingantacciyar hanyar daidaitawa ta na'ura{2}.
Samar da sanyaya: Ana buƙatar ci gaba da samar da na'ura mai sanyaya ruwa yayin aikin honing don rage tarin zafi da guntu, ta yadda za a tsawaita rayuwar dutsen honing. Bincika layin sanyaya don kwararar da ba a rufe ba kuma daidaita yawan kwarara zuwa matakin da ya dace.
II. Maƙerin Aiki da Matsayi
Ƙarfafa kayan aiki yana da mahimmanci don tabbatar da daidaiton honing. Kula da waɗannan abubuwan yayin aiki:
Zaɓin Kayan Aikin Matsawa: Zaɓi kayan aiki mai dacewa, kamar nau'in muƙamuƙi guda uku{0} ko matsi na ruwa, dangane da sifar aikin don tabbatar da kafaffen matsi ba tare da lalata saman aikin ba.
Maganar Matsayi: Dole ne aikin aikin ya kasance mai da hankali tare da sandar injin yayin dannewa. Za a iya amfani da fil ɗin dowel ko mandrel don taimakawa tare da daidaitawa da hana gudu yayin aikin injiniya.
Clamping Force Control: The clamping force should be limited to prevent workpiece deformation and compromised dimensional accuracy after honing.
III. Saitin Ma'auni
Sakamakon mashin ɗin na'urar honing ya dogara da saitunan sigina masu dacewa, da farko sun haɗa da:
Daidaita saurin gudu: saurin jujjuyawar kan honing yawanci jeri daga 200{3}} 1000 rpm. Ya kamata a daidaita ƙayyadaddun ƙimar bisa ga kayan aikin aiki da diamita na rami. Matsakaicin sauri ya dace da kayan aiki mai wuyar gaske, yayin da ƙananan gudu ya dace da sassa masu laushi ko bakin ciki.
Gudun Ciyarwa: Gudun ciyarwar axial na honing kai yana rinjayar ƙarewar ƙasa. Saurin da yawa na iya haifar da konewa, yayin da jinkirin ya haifar da rashin inganci. Gabaɗaya ana sarrafa shi a cikin kewayon 0.5-5 mm/s.
Honing Stroke: Daidaita kewayon mai amsawa na shugaban honing don tabbatar da ɗaukar hoto na gabaɗayan mashin ɗin, guje wa juzu'i ƙarƙashin - injuna ko sama da haka{1}}machining.
IV. Rigakafi Lokacin Aiki
Pre{0}Binciken Farko: Tabbatar da cewa duk abubuwan da aka gyara (kamar honing head, fixture, da tsarin sanyaya) an shigar dasu yadda yakamata kuma basu da sako-sako ko rashin lahani.
Gudun Gwaji: Kafin yin injina na yau da kullun, yi gwajin gwaji na babu{0}}ƙasa ko ƙarami{1} don lura da motsin kan mai ɗorewa da duk wani girgiza ko hayaniya mara kyau.
Ainihin{0}Sabbin Lokaci: Yayin aikin injina, saka idanu kan kwararar sanyi da ɗumbin dutse, dakatar da injin don daidaitawa idan ya cancanta.
Kulawa A Lokacin Ragewa: Bayan yin injin, tsaftace kan honing da kayan aikin injin kowane tarkace, bincika lalacewa da maye gurbin lalacewa da sauri.
V. Laifi gama gari da Magani
Fiye da diamita na ramin haƙuri bayan honing: Wannan na iya zama saboda rashin daidaituwar tashin hankali ko saurin ciyarwa; sigogi na buƙatar gyarawa.
Rashin ƙazanta mara kyau: Duba dutsen honing don tsananin lalacewa ko rashin isasshen sanyaya da ke haifar da tara tarkace.
Jijjiga kai mara al'ada: Wannan na iya kasancewa saboda shigar da kayan da ba daidai ba ko lalacewa mai ɗaukar dunƙule; na'urar tana buƙatar raguwa don dubawa da kulawa.
Jagorar aikin sassan injin honing yana buƙatar haɗin ilimin ka'idar da ƙwarewar aiki. Daidaitaccen shigarwa, daidaitawa, da saitin sigina na iya haɓaka inganci da ingancin aikin honing yayin da rage lalacewa da tsagewar kayan aiki. Kulawa na yau da kullun da daidaitaccen aiki shine mabuɗin don tabbatar da tsayin daka{2}} na injin honing.
