摘要： An installation tool, fastener, and method for installing the fastener are disclosed. The installation tool has control fingers which control the position of the fastener with respect to the plunger and workpiece to which the fastener is to be attached during the entire travel of the fastener from the entry into the installation tool to installation in the workpiece. The fingers are pivotally mounted to the plunger and travel with the plunger throughout the installation path. The fingers are adapted to engage the fastener in a displaced area on the fastener so that the fingers can control the fastener through installation of the fastener into the workpiece. The displaced area is positioned between the top and bottom of the fastener so that the fingers can maintain control throughout installation.

摘要： A self-attaching fastener installation head and feed mechanism including a spring-biased L-shaped feed pawl which feeds a first nut in the feed passage adjacent the plunger passage on the upstroke of the die press. The feed pawl is pivotally supported on a slide bracket which includes a roller in the longitudinal axis of the feed passage which is biased against a central cam surface on the base and the base is interconnected to the nose member by removable pins. A spring biased nut restrictor is pivotally supported on the nose member, simplifying removal of a nut strip from the head and the installation head is more rugged in design and has fewer parts, reducing costs.

摘要： The disclosed method and apparatus is adapted to attach a self-attaching fastener, such as a pierce or clinch nut or stud to a metal wall of an enclosed structure, such as a tube, from inside the structure. The method includes rigidly supporting the self-attaching fastener within the enclosed structure on an anvil with the fastening portion extending toward and located adjacent an inner surface of the wall. A die member is then driven against the outer surface of the wall to deform the wall into locking engagement with the self-attaching fastener. Where a pierce nut or stud is used, the nut simultaneously pierces the wall from inside the structure and clinches the wall as the die member is driven against the outer surface of the wall. The apparatus includes an expandable anvil assembly having opposed surfaces which conform generally to the opposed surfaces of the enclosed structure and a pocket which receives and rigidly supports the body portion of the self-attaching fastener. The anvil assembly further includes relatively movable parts having mating inclined surfaces and the parts are moved to expand or contract the anvil assembly. The method then includes inserting the body portion of a self-attaching fastener in the anvil pocket, inserting the anvil in the enclosed structure, then expanding the anvil to locate or position the fastener adjacent the inner surface of the wall. The die member then installs the nut in the wall. Finally, the anvil is contracted to remove the anvil from the assembly.
摘要翻译： 所公开的方法和装置适于将结构上的附接紧固件（例如穿孔螺母或螺柱或螺栓）附接到封闭结构（例如管）的金属壁。 该方法包括将封闭结构内的自连接紧固件刚性地支撑在砧座上，其中紧固部分朝向并邻近壁的内表面定位。 然后将模具构件抵靠壁的外表面驱动，以将壁变形成与自连接紧固件锁定接合。 在使用穿孔螺母或螺栓的情况下，当模具构件被驱动抵靠壁的外表面时，螺母同时从结构内部穿透壁并且紧固壁。 该装置包括具有相对表面的可膨胀砧座组件，该相对表面大体上与封闭结构的相对表面相一致，并且该凹槽容纳并刚性地支撑自固定紧固件的主体部分。 砧组件还包括具有配合的倾斜表面的相对可移动的部件，并且部件被移动以使砧座组件膨胀或收缩。 然后，该方法包括将自连接紧固件的本体部分插入砧座中，将砧座插入封闭结构中，然后使砧座膨胀以将紧固件邻近壁的内表面定位或定位。 然后，模具将螺母安装在墙壁上。 最后，砧座被收缩以从大会上拆下砧座。
