Abstract
A base which is easily clamped or bolted to work being drilled, attached to the base a support column with its longitudinal axis perpendicular the work surface, a body that can be adjusted and fixed anywhere along the support column, and a thrust bearing spindle assembly offset and parallel to support column that is threadedy engaged with body. The thrust bearing is rotated by hand thereby providing a force urging the spindle towards the work, the spindle that turns independently of thrust bearing, is easily engaged by variety of hand and power tools on one end and has a drill chuck on the opposite end.
Description
Portable Drill Press In order to be practical, it is necessary that a drill press be quickly and easily mounted on substantially any surface. In prior art, a large electro-magnet(s) forms the base of a drill press. Magnetic base drill presses, being expensive and complex, prove inadequate when the drilling is done on non ferrous metals. Being large and heavy, accurate placement may prove difficult.
The present invention pertains to a portable drill press apparatus that includes: a base that is easily clamped or bolted to the surface being drilled and a perpendicular column that extends from the base. Said apparatus has a sleeve means of adjusting and securing the apparatus in relation to material being drilled. The apparatus has a spindle with a hexagonal shape on one end and a drill chuck at the other, and further this apparatus has a pressure means threadedly engaged to force the spindle assembly into the surface being drilled.
It is the object of the present invention to provide a powerful portable drill press apparatus that can be clamped or bolted to the work and a hole drilled manually (utilizing a hand ratchet and socket, or wrench).
It is a further object of this invention to provide a portable drill press that can utilize the power of a variety of electric or pneumatic tools (drills, air ratchets and the like) to assist in the drilling of holes.
It is a further object of this invention to provide a portable drill press that can be configured in a variety of ways, so that holes can be drilled in otherwise inaccessible positions and locations.
These and other objects of this invention will become apparent to those skilled in the art upon the consideration of the accompanying specifications, claims and drawings.
~ ~I
This invention is generally comprised of: (1) Body assembly, (that includes a (8) Spindle and a (15) Pressure Screw assembly), (20) a Support Column, (21) Base and (14) Drill Chuck.
Referring to the drawings, wherein like characters indicate like parts throughout the figures:
Figure 1 is an exploded isometric view;
Figure 2 is an isometric assembly view;
Figure 3 is; an elevation sectional view;
Referring to the figures the numeral (1) generally designates a parallelogram shaped body with cylindrical sections (2) and (3) on two opposing sides. Cylinders (2) and (3) have parallel holes bored through their long axis. Cylinder (2) is bored internally through and threaded for a portion of its length (4); the remaining portion is fitted with a bearing (5). Cylinder (3) is bored internally (6) and sized to slip fit on support colunm (20) that allows movement anywhere along column's length, as well as rotating 360 degrees perpendicular to the support column. Cylinder (3) is bored and fitted with a set screw (7) to secure it to support column. It should be understood that the present embodiment of this part (1) is simply for illustrative purposes and a variety of configurations might be designed by those skilled in the art, all of which come within the scope of this invention.
The spindle (8) has a hexagonal section at one end (9), and a groove next to this section (10) that allows for the placement of an external snap ring (11).
At the mid-point, the spindle has a circular flange (12). The spindle's other end is machined (13) to receive an adjustable drill chuck that holds drill bits (14).
The hexagonal section (9) provides a means of interface between the spindle and a rotational power source (e.g. wrench, socket and (air) ratchet, electric or pneumatic drill or other like means) It should be understood that the present embodiment of spindle (8) is for illustrative purposes and a variety of configurations might be designed by those skilled in the art, all of which would come within the scope of this invention.
The pressure screw (15) is a flanged cylinder that is externally threaded (16) to mate with (4), and is bored longitudinally (17), and fitted with internal axial and thrust bearings at each end (18) and (19) to receive spindle (8) and allow for free rotation of the spindle. The pressure screw is captured between (11) and (12) and this thrust bearing assembly is then threadedly engaged with (4).The flange portion of (15) is knurled to aid with finger grip. When this thrust bearing assembly, see figure 2, is threadedly engaged with (4) turning the flange clockwise moves this assembly into the work being drilled, when the hole has been drilled, turning the flange counter clockwise moves this assembly in the opposite direction and retracts the drill bit from the work.
The support column (20) is a cylindrical shaft.
The base (21) is generally a rectilinear shape with a cylindrical section at one end bored perpendicular (22) to its top and bottom and sized to slip fit on the support column, that allows movement anywhere along the column's length and allows it to be rotated 360 degrees perpendicular to the support column.
The base is bored and fitted with a set screw (23) to secure it to the support column.
Base assembly has slots and holes made perpendicular to its base to allow bolting to the work being drilled (24). It should be understood that the present embodiment of the base (21) is for illustrative purposes and a variety configurations might be designed by those skilled in the art, all of which would come within the scope of this invention.
