DRILLING DEVICE FOR DRILLING SIDE PORTIONS OF
LARGE SECTION MEMBERS
BACKGROUND OF THE INVENTION
The present invention relates to a drilling device for drilling
side portions of large section members.
It is already known from prior art, to cut individual section
member lengths by a band sawing machine, starting from a
section member having a length of about 6 meters and more.
As it is also known, the single section member lengths are cut
through a making cutting line, the individual section member
lengths cut to a target measurement being then loaded in
succession into a drilling machine.
Moreover, outside of the section member cutting line, other
devices are also provided for performing beveling milling
operations on the vertex region where the section member
sides meet with one another.
It should be apparent that such a provision of further devices
outside of the section member cutting line, represents a
substantial drawback, since it is .necessary to drive the section
members being cut from the saw machine cutting line to
another machine for drilling, for example, the section member
side portions.

SUMMARY OF THE INVENTION
Thus, the aim of the present invention is to overcome the
above mentioned drawbacks and provide a section member
side drilling machine or device, which is adapted to drill,
respectively mill, the section member side portions
respectively at a section member vertex point and which
machine may be fitted to different section member angles, for
example 90 and 600 angles, while allowing the drilling tool
axis to be always held perpendicular to a corresponding
section member side and the section member vertex milling
tool to be held at the section member vertex.
The above aim is achieved by a drilling device for drilling side
portions of large section members, the device being arranged
in a cutting system for cutting individual section member
lengths, starting. from a long section member, said device
comprising a base thereon swinging support arms extend, the
support arms being arranged with a V pattern, enclosing an
angle a, each support arm including a plurality of sliding rollers
for causing the section member to slide thereon, the swinging
arms including guides slidably supporting a controllably driven
carriage operatively connected to a threaded screw, each
threaded screw being operatively connected to a controllable
motor, each carriage having a movable arm which may be
controllably displaced along guides and comprising parallel

guides engaging a drilling assembly, each drilling assembly
being operatively coupled to a driving shaft, each driving shaft
being operatively connected to a corresponding controllable
motor.
BRIEF DESCRIPTION OF THE DRAWINGS
Further advantages and characteristics of the present
invention will become more apparent hereinafter from the
following disclosure, claims and accompanying drawings.
The subject matter according to the present invention will be
disclosed in a more detailed manner hereinafter with reference
to the accompanying drawings, where:
Figure 1 is a front view of the section member drilling device;
and
Figure 2 is a perspective view of the drilling device shown in
figure 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to figure 1 the device, being generally indicated
by the reference number 1 and arranged in a section member
cutting line 2, comprises a base 3, therefrom swinging support
arms .4 and 5 extend, said support arms having an adjustable
angular position and defining an angle a therebetween, as
shown in figure 1.
At the vertex 6, the arms 4 and 5 comprise a plurality of sliding
rollers 7 and 8 for facilitating the movement of the section

member 2.
The outer side of each arms 4, 5 supports precision guides 9
and 10 allowing a corresponding carriage 11, respectively 12,
to controllably slide therealong, as shown by the arrows (f) and
(9).
To that end the carriages 11 and 12 are operatively connected
to the shaft of a controllable driving motor 13, respectively 14,
each said motor 13 and 14 being arranged at the free end
portion of the arms 4, 5 and is operatively connected to the
system control assembly.
From each carriage or slide 11, 12, extends perpendicularly an
arm 15, 16 including parallel guides 17 and 18, therealong a
drilling assembly 19, 20, is slidably controllably driven in the
direction of the arrows (h) and (i).
The drilling assemblies 19 and 20 are operatively connected to
a corresponding driving threaded shaft 21 and 22, in turn
operatively connected to shaft driving controllable motors 23,
24, which are controlled, for example, by encoder means of a
per se known type, which are in turn operatively connected to
the system control means.
Each drilling assembly 19, 20 supports a machining tool 25, 26
