Hand drill

Номер: US20120141218A1
Принадлежит: Fuji Jukogyo KK

The object of the invention is to provide a hand drill that capable of suppressing delamination that occurs when drilling holes in an object, as well as being more compact. The hand drill has a base member, a damper, a drill and drill blade. The base member has a contact surface that comes in contact with an object being drilled, and a drill bushing. The damper comprises a piston rod and a cylinder, and extends or contracts in its own axial direction. The tip end section of the piston rod is fastened to the base member. The drill is fastened to the cylinder and displaces together with the cylinder. The drill blade is installed in the drill so that it is parallel to the axial direction of the damper. When the damper is in the extended state, the tip end of the drill blade is located at the tip end of the drill bushing.

Double Eccentric Positioning Apparatus

Номер: US20170114880A1
Принадлежит: The Boeing Company

A double eccentric positioning apparatus uses two equal offset eccentric bushings to accurately position a tool (such as a drill bushing) in two dimensions. Miniature servo motors and precise gearing control the rotation of each eccentric bushing, which controls the direction of the offset vectors. The offset vectors are used to determine the final position of the drill bushing. The desired rotation angles can be mathematically calculated based on desired position. The inner eccentric bushing is located concentric to the offset of the outer eccentric bushing. This allows any position, within a radius of two times the eccentric offset, to be achieved. The use of worm gearing on the eccentric bushings prevents back-driving of the servo motors, due to the lead angle of the worm gears, and the friction between the worm wheel and worm gear. 1: An apparatus comprising:an outer eccentric bushing having an outer circular cylindrical surface and an inner circular cylindrical surface off-center from said outer circular cylindrical surface of said outer eccentric bushing;a first worm wheel affixed to said outer eccentric bushing;an inner eccentric bushing having an outer circular cylindrical surface in contact with said inner circular cylindrical surface of said outer eccentric bushing and an inner circular cylindrical surface off-center from said outer circular cylindrical surface of said inner eccentric bushing;an external spur gear affixed to said inner eccentric bushing, said external spur gear having an axis which is coaxial with an axis of said outer circular cylindrical surface of said inner eccentric bushing;an internal spur gear surrounding and engaging said external spur gear, said internal spur gear having an axis which is coaxial with an axis of said outer circular cylindrical surface of said outer eccentric bushing; anda second worm wheel affixed to said internal spur gear.2: The apparatus as recited in claim 1 , wherein offsets of said inner and outer eccentric ...
