摘要： A rivet configured to provide a strengthened rivet joint capable of acting as a load-bearing joint, such as in a vehicle, is provided. A method of joining a multiple member work-piece utilizing the rivet is also provided. The rivet includes a head portion and an annular body portion extending from the head portion. The body portion has an open end opposite the head portion. The head portion and the annular body portion define an interior cavity that opens at the open end. The annular body portion has an inner surface at the interior cavity and an outer surface opposite the interior cavity. The body portion has passages extending through the body portion from the inner surface to the outer surface, and grooves running along the outer surface intersecting with the passages.

摘要： A method of joining workpieces includes rotating a friction stir rivet via a mandrel and driving the rivet into the workpieces causing frictional heating between the rivet and the workpieces and causing the materials of the workpieces to soften, thereby providing a fiction stirred displaceable path for the rivet to traverse, and driving the rivet along the displaceable path until the rivet mandrel pierces through the workpieces and a cap of the rivet is seated against the workpieces. Subsequent to seating the cap, further rotation of the mandrel is stopped and the workpieces are allowed to cool and harden. An axial load is then applied to the mandrel sufficient to provide mechanical loading between the rivet body and the workpieces. A resultant volume of displaced material from the workpieces is fixedly attached to the workpieces, thereby avoiding the creation of a potentially detachable slug of the displaced material.
摘要翻译： 连接工件的方法包括通过心轴旋转摩擦搅拌铆钉并将铆钉驱动到工件中，引起铆钉和工件之间的摩擦加热，并使工件的材料变软，从而为铆钉提供一个小型搅拌的可移动路径 穿过并沿着可移动路径驱动铆钉，直到铆钉心轴穿过工件，并且铆钉的帽抵靠着工件。 在安置盖子之后，心轴的进一步旋转停止，并且工件被允许冷却和硬化。 然后将轴向载荷施加到心轴上，足以在铆钉体和工件之间提供机械载荷。 来自工件的移动材料的合成体积被固定地附接到工件上，从而避免产生可移除材料的潜在可拆卸的块状物。

摘要： A friction stir nut is disclosed. The friction stir nut includes a body, a cap, and an anti-rotation feature. The body has an elongated cylindrical shank extending between a first end and a second end, the cap being disposed at the second end, and the anti-rotation feature being disposed at the cap and/or an outer surface of the body. The body and cap have a blind axial hole extending from the first end to the second end, the first end being blind and the second end being open. The outer surface of the first end has a flat surface oriented substantially perpendicular to the axis of the shank, and the body has a cylindrical wall thickness suitable for receiving internal threads. In response to a mandrel tool friction stir welding the friction stir nut to a workpiece and then being extracted, uniform internal threads result at the body. The anti-rotation feature bonds to the workpiece by metallurgical bonding and/or mechanical bonding.

摘要： Method and apparatus is provided for monitoring the installation of a blind rivet to attach together top and bottom members. The blind rivet installation tool includes a housing having an anvil seated on the rivet head. A collet is reciprocable within the tool housing and carries jaws for gripping the mandrel of the blind rivet. Retraction of the jaws by the collet displaces the jaws and the mandrel axially and causes the mandrel head to axially collapse and radially expand the hollow shank of the blind rivet into engagement with the bottom member so that the rivet attaches the top member and the bottom member. A cut off tool is actuated by an actuator to cut off the mandrel flush with the rivet head. Transducers and a process controller monitor the installation process and actuate the cut off blade upon determining that the blind rivet is properly installed.
