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.

Insertion tool

Iinsertion tool

A prewinder apparatus attachable to a drive tool to install a helical coil insert includes a body connected to the drive tool. An adapter rotates and is releasably connected to the body at operator selected positions. A prewinder portion displaces in/out of the body. The prewinder portion translates into the body until a fastener engaged with the prewinder portion contacts a stop member defining a predetermined helical coil insert insertion depth. A mandrel axially extends from the prewinder portion when the prewinder portion moves into the body to rotatably insert the helical coil insert. A clutch engages/disengages the mandrel from a drive member. A second clutch or a stall device stalls the drive tool after coil insertion.

Retractable prewinder assembly with infinite adjustability for installation of helically coiled wire inserts

A prewinder apparatus attached to a drive tool to install helical coil inserts includes an adapter attached to the drive tool. A rotatable tubular sleeve in the adapter is engaged with the tool drive and has opposed engagement walls of a longitudinal slot extending through a hollow portion. A mandrel has a threaded first end and a pin transversely extending from a second end positioned within the longitudinal slot. A stop slides within the adapter member and rotatably receives the sleeve. The stop has a plurality of external threads. A stop regulator rotatably disposed in the adapter member has internal threads engaged with the stop external threads. The stop is axially displaceable within the adapter member and infinitely positionable along the stop external threads by manually rotating the stop regulator. A ball or male detent member biased to engage detent cavities of the stop regulator provides predetermined stop axial displacement.

Adjustable prewinder assembly for wire insert installation tool

A prewinder apparatus for selective attachment to an installation tool is provided. The prewinder apparatus includes a support structure selectively attachable to the installation tool, a prewinder attached to the support structure, the prewinder having first and second threaded apertures, and a mandrel having a threaded end and a coupling end. The threaded end is in threaded engagement with the second threaded aperture. The coupling end is in selective operable engagement with the drive tool, whereby the drive tool rotatably drives the mandrel relative to the prewinder for rotatably driving the helical coil insert through the second threaded aperture to prewind the helical coil insert.
