Abstract
Zvýšenie produktivity práce pri dokončovacom obrábaní válcových dier s kuželovým ukončením sa dosiahne tým, že tenkostenná súčiastika s predpracovanou válcovou dierou sa na ikonci stlačí po celom obvode v oblasti pružných deformácií, a potom sa predjpracovaná válcová diera po celej dížke dokončí honovacím nástrojom.Increase Finishing Productivity machining cylindrical holes with taper by ending it by being thin-walled components with pre-machined cylindrical bore the icon is pressed across the circuit in elastic deformation area, and then pre-worked cylindrical hole across the length completes the honing instrument.
Description
Vynález sa týká dokončovacieho spůsobu obrábania válcových dier s kuželovým ukončením, vhodný pre takéto diery vytvořené v tenkostenných súčiastkach.The invention relates to a finishing method for machining cylindrical holes with a tapered end suitable for such holes formed in thin-walled components.
Jemné opracovanie vnútorných kuželových plůch tenkostenných súčiastok (puzdrá, vložky valcov spalovacích motorov) je možné zabezpečoval viacerými známými spůsobmi ako Je brúsenie, superfinišovanie, lapovanie, leštenie, valčekovanie a podobné.Fine machining of the inner conical surfaces of thin-walled components (bushings, cylinder liners of internal combustion engines) can be accomplished in several known ways such as grinding, superfinishing, lapping, polishing, rolling and the like.
Nevýhodou uvedených epůsobov je poměrně nízká produktivita práce a geometrická přesnost opracovaného otvoru.The disadvantages of the above mentioned methods are relatively low productivity of work and geometric accuracy of the machined hole.
Uvedené nevýhody sú ešte výraznejšie pri Opracovaní tenkostenných súčiastok s prechodom vnútornej kuželovej plochy do valcovej.These disadvantages are even more pronounced when machining thin-walled parts with the transition of the inner conical surface to the cylindrical part.
Uvedené nevýhody odstraňuje spůsob dokončovacieho obrábania válcových dier s kuželovým ukončením podía vynálezu, kto02 3 rého podstata spočívá v tom, že súčiastka s predpracovanou válcovou dierou sa na konci stlačí po čelom obvode v oblasti pružných deformácií a potom sa predpracovaná válcová diera po celej dížke dokončí honovacím nástrojom.The above-mentioned disadvantages are eliminated by the method of finishing machining of tapered cylindrical bores according to the invention, which consists in that the workpiece with the pre-worked cylindrical bore is compressed at the end in the area of elastic deformations and then the pre-worked cylindrical bore is tool.
Výhody sposobu podlá vynálezu sú v jeho jednoduchosti a zvýšení produktivity práce.The advantages of the method according to the invention are in its simplicity and increase in labor productivity.
Tenikostenná súčiastka zo šedej liatiny s predpracovanou válcovou dierou sa na konci stlačí v oblasti pružných deformácií po celom obvode tak, že na koniec súčiastky sa nalisuje sťahovacie puzdro s kuželovou dierou. Takto upravená súčiastka sa upne do honovacieho stroja a predpracovaná válcová diera súčiastky sa honovacím nástrojom dokončí po celej dížke, napr. na 0 39,020 mm. Potom sa z konca súčiastky odstráni sťahovacie puzdro, čím sa koniec valcovej diery roztiahne na 0 39,065 mm.The thin-walled gray cast iron part with the pre-worked cylindrical bore is compressed at the end in the region of elastic deformations along the entire circumference so that a tapered sleeve with a conical bore is pressed onto the end of the part. The treated part is clamped into the honing machine and the pre-machined cylindrical hole of the part is completed with the honing tool over the entire length, e.g. to 0 39,020 mm. Then, the shrink sleeve is removed from the end of the part, thereby expanding the end of the cylindrical bore to 0 39.065 mm.
