Abstract
Expandable collet bodies with sectional finger-based anti-rotation features are disclosed. The collet body comprises not only a plurality of gripping finger as a first part of a two-part anti-rotation means (ARM), but also a first part of a two part translation arresting means (TAM), which may or may not be sectional in nature. The TAM prevents over translation of a collet body within the work piece(s), and cooperates with a second part of the TAM associated with a work piece or an auxiliary structure. In this manner, a collet body inserted into a work piece or auxiliary structure will not accidentally be pushed beyond the blind side of the work piece(s) during insertion or initial clamp-up.
Claims15
A sleeve insert, comprising:
- a cylindrical wall;
- a flange extending outwardly from the cylindrical wall;
- a bore defined between a proximal opening and a distal opening;
- and
- a first protuberance disposed within the bore at the distal opening;
- wherein the first protuberance extends radially inward from an interior surface of the cylindrical wall;
- wherein the first protuberance is profiled to fit in a space between two gripping fingers in a collet body and prevent rotation of the two gripping fingers of the collet body;
- and
- wherein the proximal opening is sloped inward.
A sleeve insert in a fastening system, comprising:
- a cylindrical wall;
- a flange extending outwardly from the cylindrical wall;
- a chamfered surface extending from a periphery of the flange;
- a sloped surface extending inward from the chamfered surface;
- a bore extending between an upper opening and a lower opening;
- a first protuberance disposed within the bore at the lower opening and extending radially inward from an inner surface of the bore;
- and
- a second protuberance disposed within the bore at the lower opening and extending radially inward from the inner surface of the bore;
- wherein the first and second protuberances are each profiled to fit in a space between two gripping fingers in a collet body and inhibit rotation of the two gripping fingers of the collet body;
- wherein the first and second protuberances extend radially inward;
- wherein the first protuberance includes a planar lower surface, a sloped upper surface, and two opposing sidewalls that each extend between the planar lower surface and the sloped upper surface;
- wherein the second protuberance includes a planar lower surface, a sloped upper surface, and two opposing sidewalls that each extend between the planar lower surface and the sloped upper surface;
- wherein the chamfered surface includes an upper edge and a lower edge that each have a circular profile;
- wherein a portion of the periphery of the flange has a circular profile;
- wherein the first protuberance and the second protuberance are symmetrically arranged in relation to a radially aligned plane;
- and
- wherein the lower opening includes two opposing curved surfaces.
