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.

Dependent claims

In a multiple spindle inclined drilling machine;

a base;
a bed on said base inclined at an acute angle to the horizontal in the range of 20.degree. to 40.degree., approximately;
a drill unit mounted upon said bed, said drill unit including:
an internally splined cylinder rotatively journaled within the drill unit and inclined at a corresponding acute angle;
a piston rod with a splined connection to said cylinder projecting therefrom for effecting controlled reciprocal movements;
a multiple spindle head spaced above and slidably mounted on said bed and projecting forwardly of said drill unit and connected to said piston rod for reciprocal movements therewith;
an upwardly and rearwardly inclined fixture mount plate secured upon said bed lying in a plane at right angles thereto facing said head;
spaced parallel guide support rods above, parallel to and secured at one end to said bed with the other end of each rod secured to said mount plate;
apertured support means on and adjacent the forward end of said multiple spindle head, slidably and guidably mounted upon said rods;
a rotative drive means on said drill unit having a variable speed output shaft connected to said cylinder for rotating its piston rod;
and a plurality of drive spindles with individually mounted drills adjustably supported upon and within said head and connected to and rotated by said piston rod.
