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: The described embodiment relates generally to the field of press-fit technology. Press-fit technology results in deformation of one component to lock another component in place. This deformation commonly causes surface strain to occur on the deforming component. When a component is anodized surface strain can result in anodization cracking; this ruins the finished appearance of cosmetic surfaces, generally resulting in ghosting lines and splotches appearing on the surface of a component. The described embodiment achieves a careful balance between component deformation and surface strain. By utilizing specific press-fit geometries and assembly methods, surface strain can be sufficiently limited to eliminate anodization cracking while also achieving a durable press-fit joint.

Abstract translation: 所描述的实施例一般涉及压配技术领域。 压配技术导致一个部件的变形，以将另一个部件锁定到位。 这种变形通常导致在变形部件上发生表面应变。 当组分阳极氧化时，表面应变会导致阳极氧化开裂; 这会破坏化妆品表面的完成外观，通常会导致在组件表面出现重影线和斑点。 所描述的实施例在部件变形和表面应变之间实现了谨慎的平衡。 通过利用特定的压配合几何形状和组装方法，可以充分限制表面应变以消除阳极氧化裂纹，同时还实现耐用的压配合接头。
