Abstract
A fastener installation tool including an anvil member having a swage cavity, a collet having a pull section with a fastener engagement end and a plurality of teeth, and an anvil member. The plurality of teeth includes a first tooth with a first inner diameter, and each of the remainder of teeth includes a second inner diameter, the first inner diameter being greater than the second inner diameter. The collet has a protrusion extending the length of the pull section to increase the contact area with the anvil member. The anvil member includes a swage cavity with an entrance section, a swage land located adjacent to the entrance section, and an inner bore located adjacent to the swage land.
Claims8
A fastener installation tool, comprising:
- an anvil member having a swage cavity, a first end, a second end opposite the first end, an entrance section located at the first end, a swage land located adjacent to the entrance section and having a first inner diameter, and an inner bore located adjacent to the swage land and having a second inner diameter, wherein the swage land is adapted to transmit a radially inward swage load applied by the anvil member, wherein the swage land includes a width that is smaller than a length of the anvil member extending between the first and second ends thereof;
- and
- a single split gripper collet having a pull section with a fastener engagement end and a plurality of teeth,
- wherein the plurality of teeth includes a first tooth located proximate to the fastener engagement end,
- wherein the first tooth of the plurality of teeth includes a first inner diameter and each of the remainder of the plurality of teeth includes a second inner diameter, wherein the first inner diameter of the first tooth is greater than the second inner diameter of each of the remainder of the plurality of teeth,
- wherein the pull section of the collet is movable between an open expanded position, in which the pull section is positioned external from the anvil member, and a closed constricted position, in which the pull section is positioned within the anvil member.
