Abstract
An attaching sleeve for a floating nut assembly is formed from rod or wire stock by successive cold heading or cold forming operations. The steps involve cutting off a longitudinal segment from the stock, forming a flange on the front end of the segment, forming a centrally disposed opening through the segment, and forming longitudinally extending ridges projecting outwardly around the periphery of the segment. The attaching sleeves made by the method of the present invention have accurately positioned ridges or knurls which will consistently mate with a similarly configured opening in panels to which the floating nut assembly is to be secured.
Claims4
A method for forming and securing an attaching sleeve for a floating nut assembly comprising the steps of:
- cutting off a longitudinal segment from an input bar or wire stock made of steel, said longitudinal segment having a first portion located toward a front end of said segment, and a second portion located toward a rear end of said segment;
- forming a first flange on said front end of said longitudinal segment;
- forming a first centrally disposed hole in said front end of said longitudinal segment, said hole extending rearward from said flange toward the second portion of said segment;
- forming a predetermined number of longitudinally extending knurls projecting outwardly around the periphery of said first portion adjacent said flange;
- forming a second centrally disposed hole in said rear end of said longitudinal segment, said second hole extending forward from said rear end toward the first portion, said hole communicating with said first hole to form a substantially uniform diameter opening through said segment;
- all of said forming steps being achieved by cold heading or cold deforming operations;
- trimming said flange to form outwardly extending tabs;
- preparing a hole for receiving said sleeve having recesses around the inner wall of said hole, the number of said recesses being equal to said predetermined number of cold headed or deformed knurls;
- and
- subsequent to preparing said hole, securing said cold headed or deformed sleeve into said hole by embedding or pressing said sleeve into said hole with each knurl fitting into a corresponding recess in the wall of said hole.
