Abstract

A laser centering mechanism of a drilling machine includes a support ring fitted around a support tube disposed right above the drill, first and second laser modules disposed on an edge of the support ring, and first and second adjustment combinations for holding the support ring around the support tube, and respectively for adjusting orientation of the first and the second laser modules relative to the tube. The laser modules are equipped with such lenses that laser lights emitted therefrom can form respective straight light lines on a plane thereunder, and the light lines will intersect to form a centering point on the plane. After rectification, under which the intersection is adjusted to be right under the sharp end of the drill, a predetermined point of a workpiece, on which a hole is to be drilled, can be easily positioned right under the drill precisely owing to the intersection.
