Drilling device for drilling side portions of large section members

In a system for cutting elongated section members having side portions arranged in a V-shaped configuration into predetermined lengths, a device for drilling the V-shaped side portions of each cut section member, the device comprising:

• a base;
• a pair of elongated support arms pivotably mounted on, and extending in opposite directions away from, the base, the support arms being adjustable to bound an angle between the support arms that matches the V-shaped configuration of the side portions;
• a plurality of sliding rollers mounted on each support arm to support each cut section member for sliding movement in a longitudinal direction lengthwise of each cut section member;
• a pair of elongated carriage guides mounted on, and extending lengthwise of, each support arm;
• a pair of carriages mounted on the carriage guides on each support arm for guided movement lengthwise of each support arm;
• a pair of elongated tool guides mounted on each carriage, and extending generally parallel to the longitudinal direction;
• a pair of drilling assemblies mounted on the tool guides on each carriage for guided movement generally parallel to the longitudinal direction;
• and
• a drive for moving each drilling assembly in a transverse direction generally perpendicular to the longitudinal direction into drilling engagement with the side portions of each cut section member.
