摘要： A method and apparatus for a power feed drill. The power feed drill comprises a servo motor, a roller screw, a ball spline shaft, an air motor, and a collet chuck. The roller screw is rotatably mounted to the servo motor. The ball spline shaft has a first end connected to the roller screw, wherein rotation of the roller screw in a first direction moves the ball spline shaft in the first direction and wherein rotation of the roller screw in a second direction moves the ball spline shaft in an opposite direction to the first direction along an axis. The air motor is capable of transmitting rotation motion to the ball spline shaft to rotate around the axis. The collet chuck is fixably attached to a second end of the ball spline shaft, wherein the collet chuck is adapted to receive a tool.

摘要： A collet clamping nosepiece for a power feed drill is described which includes at least one clamping piston located along a centerline of the nosepiece, an expansion mandrel comprising a frusto-conical exterior surface, and an expandable collet. The expandable collet is configured to substantially surround the expansion mandrel and operatively connect to the at least one clamping piston. Operation of the at least one clamping piston causes the mandrel to move along the exterior surface of the expansion mandrel for engagement and disengagement of the collet with a bore configured for insertion of the collet.

摘要： An apparatus having a single, elongated flexible rail with a plurality of attachment devices connected to the rail and spaced at intervals therealong for releasably affixing the rail to a surface of a work piece by vacuum. The rail bends and twists as needed to substantially follow the surface of the work piece. An X-axis carriage is coupled to the rail and adapted to traverse the rail along an X-axis, wherein the X-axis is parallel to a length of the rail. A Y-axis carriage is coupled to the X-axis and adapted to traverse the X-axis carriage along a Y-axis, wherein the Y-axis is perpendicular to the X-axis. A fastening device clamps the X-axis carriage to the Y-axis carriage. A laser associated with the X-axis carriage facilitates precise locating of a drill carried by the apparatus relative to a spot where a hole is to be drilled.

摘要： A power feed attachment that has a coupling structure to couple it to a hand held drill. A double-acting cylinder, which has a piston and a rod, and is fixedly coupled to the coupling structure. A two-position valve assembly is configured for directing a pressurized fluid to the double-acting cylinder. When the two-position valve assembly is in a first position is directs a fluid to a first side of the piston moving the piston to a first position. When the two-position valve assembly is in the second position it directs the pressurized fluid to a second side of the piston to move the piston to a second position. An arm is coupled to the piston. A control mechanism having a housing and a control rod, wherein the control rod is movable within the housing of the control mechanism between an extended position and a retracted position. The control mechanism has a biasing device for biasing the control rod toward the extended position, the control rod being configured to contact the arm to resist movement of the piston toward the second position to thereby control a rate by which the piston is advanced toward the second position. The assembly may also include a four-way two position air piloted valve to control the flow of a fluid to the arm.

摘要： A clamp including a vacuum base having a seal adapted to engage a first object. A cavity is defined between the first object and the seal. The clamp includes a vacuum generator connected to the cavity for reducing pressure in the cavity and a clamping member mounted on the vacuum base for engaging a second object. The clamp further includes a valve connected between the cavity and the vacuum generator. The valve is selectably positionable between an open position allowing fluid communication between the vacuum generator and the cavity for generating a pressure inside the cavity that is lower than a pressure outside the cavity, and a closed position at least partially restricting fluid communication between the vacuum generator and the cavity for at least partially preventing air from entering the cavity when pressure inside the cavity reaches a predetermined maximum.
