Iinsertion tool

摘要

An insertion tool is used to insert a threaded coil insert into a threaded opening of a support structure. The tool includes a rotatable mandrel body having an axial longitudinal passage and a projection slot. A plunger is disposed in the passage forward of a spring which urges the plunger forward. The plunger in turn urges a drive projection. A front end of the plunger includes an inclined surface that slidingly and inclinedly engages an inclined surface of the drive projection. The urging of the drive projection by the plunger along their respective inclined surfaces causes relative sliding movement of the drive projection so that the drive projection translates linearly through the projection slot in a direction perpendicular to the longitudinal passage.

1. A method of using an insertion tool to install a threaded insert into a support structure comprising the steps of:
providing a rotatable mandrel having a mandrel insertion end and a driven end located at opposite ends of a longitudinal axis of the mandrel; providing a first passage formed in the mandrel along a directional axis that is generally perpendicular to the longitudinal axis, the first passage defining a projection slot at a first end thereof and an assembly slot at a second opposite end thereof; providing a drive projection confined to travel within the first passage along the directional axis, the drive projection including a drive hook for engaging the threaded insert; providing a biasing member engaged with the drive projection such that the biasing member urges the drive projection along the longitudinal axis to extend the drive hook proud of the projection slot; inserting the insertion end of the mandrel into the threaded insert; engaging an edge of the hook with a drive notch of the threaded insert; and rotating the mandrel to drive the threaded insert into the support structure.
