US 11,890,708 B2 · Mechanical variable gap crimp tool

Abstract

A tool head assembly for crimping, the assembly including an internal cam that spins freely on a stationary shaft in one direction and locks onto the shaft in the other direction. That cam rotates against the moving slide forcing to move away from the stationary shaft opening a gap between rollers. A controller is programmed to have the drive rotate in one direction for a set time period, then reverse the rotation to begin the crimp process. The start rotation of the drive rotates the cam and opens the roller gap. The forward rotation allows the cam to swing, closing the gap and rotating the rollers around a seal. The tool eliminates the air cylinder and related pneumatic hoses and valve making the head smaller and allows a controller to communicate with any OEM production system to verify the tool has been used and was used correctly.

Dependent claims

A tool head assembly adapted to secure a part to a structural member, comprising:

a drive shaft rotatable about a first axis of rotation,
a cam operably coupled to the drive shaft,
a cam bearing operably coupled to the cam,
a first roller operably connected to the drive shaft
a slidable shaft rotatable about a second axis of rotation and slidable along an elongated aperture;
a moving slide operably coupled to the slidable shaft;
and
a second roller operably connected to the slidable shaft;
wherein said cam selectively rotates against said moving slide forcing said moving slide to move away from said drive shaft opening a gap between said first and second rollers.
