Abstract
A drill jig assembly for drilling holes in an extruded aluminum shape; including a metal channel base, a plastic plate having upright hole patterns and a plurality of position pins located in the holes for positioning the shape widthwise for drilling, and an extension arm for positioning a stop pin against which the shape can be positioned lengthwise for drilling. This jig is used principally for drilling assembly holes in an aluminum window vertical frame piece to correspond to a pair of spaced sprues in the horizontal frame piece and different positioning pins are required for different shapes and different hole patterns in the plate likewise are required to accommodate for different shapes.
Claims15
A drill jig assembly for positioning a workpiece on a bed of a drill press for drilling holes in the workpiece;
- said assembly including a holder channel attachable to the bed;
- a jig plate disposed within said channel adapted to be clamped to said channel to provide a horizontal planar upper surface, said jig plate having a plurality of spaced vertical holes through said upper surface, a plurality of guide pins insertable into selected holes in said jig plate to position the workpiece to permit drilling a hole therethrough, said guide pins being upright and transverse of the workpiece, and an adjustable stop subassembly attachable to said holder channel to provide longitudinal positioning of the workpiece for drilling other holes in the workpiece anywhere along its length greater than one half the length of said planar upper surface.
A drill jig assembly for use with a drill press for drilling holes in selected locations in a metal window vertical frame piece;
- said assembly comprising a metal channel base having spaced side walls and a bottom therebetween, a plastic plate fitting within said channel base and fastened thereto with spaced clamping screws extending through said side walls, a plurality of T-shaped fixtures positionable to project upwardly from said plate for use in positioning the vertical frame piece for drilling aligned holes therein, spaced adjustable screw means extending through said bottom to support said plate with respect to said channel base in a level position;
- and adjustable means to position a stop at a selected position with respect to said plate to assist in positioning the vertical frame piece for drilling aligned holes therein.
