The present invention relates to aircraft drills, more specifically to battery powered aircraft drills.
The aircraft industry has commonly utilized a pneumatic right angle drill for years. An air hose has to be attached to a pneumatic right angle drill for operation, which decreases the effective range of use of the drill and requires extra equipment to utilize the drill.
The present invention relates to a battery powered right angle aircraft drill comprising a motor, an adapter collar, a spindle gear shaft, and an angled head. The motor comprises an electrically powered motor providing rotational force to a shaft at suitable rotation speeds for working with airplane materials. The adapter collar secures the motor to the angled head, establishing a formlocking connection between the motor and the angled head along an axis, the adapter being annular and having an opening extending therethrough. The shaft of the motor is cooperatively joined to the spindle gear shaft, thereby translating its force.
The spindle gear shaft has a first end extending to a second end, the first end joined to the shaft of the motor, the second end of the spindle gear shaft includes splines. The angled head includes splines mating to the splines of the spindle gear shaft, and further includes a tool bit receptacle, the tool bit receptacle angularly oriented from the axis, whereby the rotational force of shaft of the motor is translated through the spindle gear shaft to the angled head, actuating a tool bit in the tool bit receptacle.
These and other features, aspects, and advantages of the invention will become better understood with reference to the following description, and accompanying drawings.
Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.
The present invention is directed to a battery powered right angle aircraft drill.
The battery powered right angle aircraft drill 10 includes an electrically powered motor 12 for providing rotational force. An exemplary electrically powered member 12 is an electric motor, such as the illustrated battery powered motor 12. The battery powered motor 12 is an electrical machine that converts electrical energy into mechanical energy. In the current embodiment, a battery 14 is the power source and the mechanical energy output is delivered via a shaft 15. A switch 13 allows a user to power the motor 12, which activates the motor 12 and rotates the shaft 15. In certain configurations, a variable speed trigger 13, allows a user to vary the output of the motor 12, which powers the motor 12 and rotates the shaft 15. The throttle handle 13, varies the output power, in turn varying the RPM, with an optional stop plate on the throttle handle 13 limiting the RPM range.
Suitable rotation speeds are those which rotate the tool bit 50 in range for working with airplane materials, such as aluminum on airplanes. In certain configurations, a suitable target rotations per minute (RPM) range to the head would rotate between 2500 RPM-4000 RPM.
An example adapter collar 20 is illustrated in
An exemplary spindle gear shaft 30 has a first end 32 and second end 34. In certain embodiments, a head 36 extends from the first end 32. In certain configurations, the head has a shaped cross-section, being generally triangular in the figure. The spindle gear shaft 30 extends to the second end 34. In the illustrated embodiment, the shaft 15 of the motor 12 extends through the opening 26 to the second end 34 of the adapter collar 20. An example spindle gear shaft 30, operable to further translate the mechanical force from the shaft 15, is illustrated in
An exemplary angled head 40, operable to further translate the mechanical action from the shaft 15, is illustrated in
A suitable tool bit 50 is illustrated in
In exemplary embodiments, the battery powered motor 12, adapter collar 20, spindle gear shaft 30, and right angle head 40 are joined together in a formlocking connection along the axis 18. The battery powered motor 12 may be enclosed or partially enclosed in housing 16. The shaft 15 of the motor 12 extends from the housing 16 and is enclosed within the adapter collar 20. The shaft 15 is cooperatively, securely attached to the first end 32 of the spindle gear shaft 30. The second, splined end 32 of the spindle gear shaft 30 is further cooperatively, secured to the right angle head 40, with the tool 10 being ready for a user at that point, at which a tool bit is mountable. A user engages a threaded tool bit 50 to the counter-threaded tool bit receptacle 46 of the right angle head 40. The user then engages the threaded aircraft drill bit 50 to the work surface, pressing it against a workpiece, and depresses the switch 13 of the electric motor 12 to power the drill and pushed the right angle head 40 against the work surface.
Insofar as the description above and the accompanying drawing disclose any additional subject matter that is not within the scope of the single claim below, the inventions are not dedicated to the public and the right to file one or more applications to claim such additional inventions is reserved.
