Design of measuring appliance for checking geometric characteristics of thin walled forged part

Podjetja težijo k čim hitrejšemu in zanesljivemu merjenju izdelkov, ki je hkrati ekonomično ugodno. Zato se v določenih primerih poslužijo merilnih priprav, s katerimi omogočijo ekonomično ugodnejše meritve pri nadzoru geometrijskih značilnosti večje količine izdelkov. V ta namen smo se v podjetju Unior d.d. odločili za izdelavo zasnove merilne priprave, ki bi bila najprimernejša za merjenje tankostenskega odkovka s specifičnimi geometrijskimi zahtevami. V nalogi sem na osnovi definiranih dimenzij in toleranc določil geometrijske značilnosti kalibrov za preverjanje pozicij izvrtin in analiziral odstopanja centrov izvrtin že izdelanih izdelkov. Na osnovi izvedene analize sem skonstruiral tri variante, katere smo na podlagi lastnih ocenjevalnih kriterijev ocenili. Izbrali smo konstrukcijsko in cenovno najbolj ugodno rešitev ki je predstavljena, na koncu diplomskega dela.Companies are tilting to fast and reliable product measurements, which are also cost efficient. Therefore, special measuring appliances, securing cost efficient measurement of bigger number of pieces are widely used. For that purpose, in company Unior d.d. was decided to design a measuring appliance, which will be most suitable for checking geometric characteristics of a thin-walled forged part with specific geometrical characteristics. In the thesis, I have calculated geometrical characteristics of plug gauges for inspecting hole positions, analyzed deviations of previous parts and designed three models, which were evaluated based on our own criteria. Chosen model with the most suitable design and economical efficiency, is presented at the end of the thesis
