  • Direct drive variable crimp on flange tool
    Patent number: 8819908
    Abstract: A crimping assembly is provided for securing a cover part to a structural member. The crimping assembly includes a housing, a drive shaft disposed within the housing and rotatable in a first direction, and a first roller fixedly secured to the drive shaft and rotatable therewith. The crimping assembly also includes a slide shaft disposed within the housing and rotatable in a second direction. A second roller is fixedly secured to the slide shaft and rotatable therewith. A drive mechanism is operably coupled to the drive and slide shafts to roll the first and second rollers over the cover part to secure the cover part to the structural member. A coupling mechanism is operably connected between the drive shaft and the slide shaft to allow movement of the slide shaft towards and away from the drive shaft during operation of the crimping assembly to accommodate variations in flange thickness.
