Abstract
A device and system for a rotary boring tool that enables a user to align the tool with respect to a target work surface is disclosed. The alignment system includes a rotating member that is mounted on the rotating portion of a rotary boring tool, and a separate portable stationary member that is designed to reside on the work surface. The rotating member includes a focused light source, such as a laser, that projects a light beam parallel to the direction of the rotary boring tool bit onto the stationary member which reflect the beam and produces a visible pattern on the surface of the stationary member that indicates alignment or misalignment of the rotary boring tool with respect to the work surface.
Claims25
A device to assist the alignment of a boring tool, said device comprising
- a hollow member with a central opening, said hollow member having a top layer, said top layer having a transparent inner region and a translucent outer region,
- said hollow member further comprising a set of internal reflecting surfaces that define a first path internal to said hollow member, said first path proceeding from said transparent inner region to said translucent outer region, wherein when a light beam is directed toward said device, said beam passes through said transparent inner region, and is reflected to a location wherein it impinges on a bottom surface of said top layer in said translucent outer region.
A system for the alignment of a boring tool, said system comprising a light source for creating a focused beam of light, said light source adapted to be attached to a penetrating cutting element that is rotated by said boring tool, and a stationary member, said stationary member having a top layer with a transparent region and a translucent region, said stationary member further comprising a first set of internal reflective surfaces that are oriented to direct said focused beam of light that passes through said transparent region to a bottom surface of said top layer to impinge at a location in said translucent region and thereby define a first path, wherein when said light source is rotated said light beam creates a visible image in the shape of an arc on the transparent region of said stationary member.
