Presspassung ist eine g\u00e4ngige Art der mechanischen Verbindung. Die Toleranz der Presspassung unterscheidet sich von Kunststoff- und Stahlteilen. Wenn das Ausma\u00df des \u00dcberma\u00dfes zu gro\u00df ist, k\u00f6nnen die Kunststoffteile unter Presspassung leicht brechen.<\/p>\n\n\n\n

Erl\u00e4utern wir einige Details des tats\u00e4chlichen Falles, der sich bei SYM Precision Machining Shop ereignet hat.<\/p>\n\n\n\n

Schauen Sie sich das Bild der Zeichnung als unten, wir immer die bearbeiteten Teile nach Kundenzeichnung.<\/p>\n\n\n\n

Material: PVC
An der Seitenfl\u00e4che befinden sich zwei L\u00f6cher zum Einpressen eines PIN-D\u00fcbels.
Lochgr\u00f6\u00dfe: 6,25 mm
Stiftgr\u00f6\u00dfe: 6,35 mm<\/p>\n\n\n\n

F\u00fcr diese beiden L\u00f6cher gibt es keine genauen Toleranzen. Wir halten die Toleranzen +\/- 0,1 mm ein und fertigen die Bohrung ebenfalls auf 6,15-6,35 mm, sofern nicht anders angegeben.<\/p>\n\n\n\n

Beim ersten Mal bohrten wir die L\u00f6cher nahe an der unteren Toleranzgrenze, 6,15-6,25 mm. Das Ergebnis der Montagearbeiten war, dass die Kunststoffteile Risse bekamen.<\/p>\n\n\n\n

\n
\"\"<\/a><\/figure>\n<\/div>\n\n\n\n

Beim zweiten Mal haben wir die L\u00f6cher in der N\u00e4he des oberen Spielraums angebracht, 6,3-6,35 mm. Der Zusammenbau verl\u00e4uft ebenfalls ohne Probleme.<\/p>\n\n\n\n

Um das Bearbeitungsproblem zu verringern.<\/p>\n

Zuallererst sollten wir bei der Entwicklung von Produkten die Ma\u00dfe mit engen Toleranzen f\u00fcr die Presspassung festlegen.<\/p>\n

Andererseits muss der Bearbeitungsbetrieb sehr professionell sein.<\/p>\n
