Abstract: Glue-free hinge assemblies including press-fit pins are disclosed. A press-fit pin of one material can mechanically attach to a workpiece of another material during a press fit operation. The press-fit pin can include a pin shaft having a chamfered first end, a notched portion, a grooved portion having axial grooves, a clinching feature, and a sealing feature. The chamfered first end can guide the press-fit pin into a counter-bored receiving hole in the workpiece. The axial grooves can etch the workpiece material to rotationally lock the press fit-pin into the receiving hole. The clinching feature can plastically deform workpiece material into the notched portion to axially lock the press-fit pin into receiving hole without causing substantial axial expansion of the workpiece. The sealing feature can form a stepped fit between an outer diameter of the press-fit pin and an outer diameter of the counter-bored receiving hole.

Abstract translation: 公开了包括压配销的无胶合铰链组件。 在压配合操作期间，一种材料的压配销可以机械地附接到另一材料的工件。 压配销可以包括具有倒角的第一端，切口部分，具有轴向凹槽的开槽部分，铆接特征和密封特征的销轴。 倒角的第一端可以将压配销引导到工件中的反孔接收孔中。 轴向槽可以蚀刻工件材料，以将压配合销旋转地锁定到接收孔中。 夹紧特征可以将工件材料塑性地变形到切口部分中，以将压配合销轴向锁定到接收孔中，而不会引起工件的显着的轴向膨胀。 密封特征可以在压配合销的外径和反钻孔接收孔的外径之间形成阶梯式配合。
