ABSTRACT:
A multiple spindle inclined drilling machine includes a base having a bed inclined at an acute angle and with guideways upon said bed. A slide is reciprocally mounted upon said ways and is connected to a piston rod of a cylinder assembly mounted upon said base for effecting reciprocal movements thereof. A multiple spindle head is mounted upon said slide. An apertured fixture adapter is mounted upon said bed and lies in a plane at right angles thereto. A rotative drive mechanism is mounted upon said bed and has a variable speed output shaft. A plurality of drive spindles with individually mounted drills is adjustably supported upon and within said head and connected to said drive mechanism. An upwardly and rearwardly inclined fixture mounting plate spans and is secured to said adapter for supporting a workpiece mounting fixture. A series of variably located drill guide bushings are nested within said fixture and arranged in a predetermined pattern for receiving the drills upon the plurality of prelocated spindles.
