Abstract
A system for aligning the bit of a hand-held tool with the surface of a workpiece wherein a laser beam essentially parallel to the axis of the bit is projected forwardly toward the workpiece and onto a mirror maintained at a preselected angle to the workpiece surface. The incident beam is reflected backwardly onto means detecting both the incident beam and the reflected beam and indicating when the beams are coincident.
Claims10
An alignment system for a hand-held tool having an axial bit to be aligned at a preselected angle to the surface of a workpiece comprising:
- a laser beam source fixed to the tool emitting a beam extending toward the workpiece along a path substantially parallel to the axis of the bit;
- a planar mirror adapted to be positioned on the workpiece surface at said preselected angle thereto and in the path of the beam so as to intercept the incident beam and reflect it therefrom;
- and
- means disposed between said laser beam source and said planar mirror detecting both the incident beam and the reflected beam and indicating when the beams are coincident.
A method for aligning a hand-held tool having an axial bit at a predetermined angle to the surface of a workpiece, comprising the steps of:
- providing a laser beam source fixed to the tool emitting a beam extending forwardly toward the workpiece along a path substantially parallel to the axis of the bit;
- providing a planar mirror on the workpiece surface at said predetermined angle thereto in the path of the beam so as to intercept the incident beam and reflect it backwardly toward the tool;
- and
- providing detection means disposed between the laser beam source and the mirror detecting both the incident beam and the reflected beam, and manipulating the tool so that the beams are coincident.
