Abstract
An apparatus for drilling structural shapes such as angles, I-beams and H-beams has sliders shiftable transversely to the beam along vertical and horizontal members of a frame through which the beam is passed. At least one of the sliders can have a rotatable carrier whose axis is perpendicular to the web or flange being drill and from which a respective drilling unit is radially offset. The longitudinal position of drilling is determined by the angular position of the carrier and any transverse offset is compensated by movement of the respective slider.
Claims11
An apparatus for machining a structural shape having angularly adjoining horizontal and vertical flanges, said apparatus comprising:
- means forming a substantially horizontal transport path for the structural shape to be machined;
- a frame along the path having at least one fixed vertical member and at least one fixed horizontal member extending generally parallel to the respective flanges;
- a horizontally displaceable slide on the horizontal member;
- a vertically displaceable slide on the vertical member;
- and
- respective machining units on the slides for machining the respective flanges of the structural shape on the path in the frame, and including
- a drill carrier rotatable on one of the slides about a respective carrier axis transverse to the respective flange, and
- a plurality of holders for a drill bits on the carrier radially offset from the carrier axis and rotatable about respective drill-bit axes angularly spaced around the carrier axis,
- whereby the holders can be set to drill holes in the respective flange at different longitudinal locations along the respective flange upon rotation of the carrier about the respective carrier axis and at different transverse locations on the respective flange on displacement of the one slide along the respective member.
