ABSTRACT:
A laser centering mechanism of a drilling machine includes a clamp ring fitted around a drill chunk of a drilling machine, upper and lower knobs, and two laser modules. The clamp ring has several spaced upwards-sticking flexible plates, and several downwards-sticking flexible plates. The knobs are fitted around an upper end, and a lower end of the clamp ring respectively. The knobs are securely screwed to each other so that inner annular portions thereof make corresponding flexible plates tightly and securely pressed against the drill chunk. The laser modules are fixed to an inner edge of the lower knob, and are equipped with such lenses that laser lights emitted therefrom form intersecting straight light lines on a plane under them, which will form a centering light point on a central axis of the lower knob in rotation of the present mechanism together with the drill chunk.
