Abstract
A vacuum attachment device for a nutplate drill motor having a footpiece and at least one cutting tool. The vacuum attachment device comprises a body portion and a nozzle portion. The body portion has a central aperture which engages the footpiece and an air chamber which extends through the body portion and intersects the central aperture to form a vacuum path. The nozzle portion is coupled to the body portion and is in fluid connection with the air chamber. The nozzle portion is coupled to a source of vacuum pressure. During the operation of the nutplate drill motor, dust and chips that are generated by the cutting tool are drawn by the source of vacuum pressure into the air chamber and through the nozzle portion.
Claims20
A vacuum attachment device for a nutplate drill motor having a footpiece and at least one cutting tool, the vacuum attachment device comprising:
- a body portion having a central aperture and an air chamber, the central aperture adapted to engage the footpiece, the air chamber extending through the body portion and intersecting the central aperture to form a vacuum path;
- and
- a nozzle portion coupled to the body portion, the nozzle portion being in fluid connection with the air chamber, the nozzle portion adapted to be coupled to a source of vacuum pressure;
- wherein dust generated from the at least one cutting tool while the nutplate drill motor is being operated is drawn by the source of vacuum pressure into the air chamber and through the nozzle portion.
A drill motor comprising:
- a rotatable spindle;
- a footpiece spaced axially apart from the spindle, the footpiece having a tool bore and chip aperture, the chip aperture intersecting the tool bore;
- a cutting tool rotatably coupled to the spindle, the cutting tool extending through the tool bore in the footpiece;
- and
- a vacuum attachment device coupled to the footpiece, the vacuum attachment device including a body portion and a nozzle portion, the body portion having a central aperture and an air chamber, the central aperture engaging the footpiece, the air chamber extending through the body portion and intersecting the central aperture to form a vacuum path, the air chamber generally aligned to the chip aperture;
- and
- a nozzle portion coupled to the body portion, the nozzle portion being in fluid connection with the air chamber, the nozzle portion adapted to be coupled to a source of vacuum pressure;
- wherein dust generated from the cutting tool when the drill motor is being operated is drawn by the source of vacuum pressure into the air chamber and through the nozzle portion.
