摘要： A compact autofeed drill is provided and generally comprises an elongate housing having opposed ends, a motor disposed within the housing, an elongate drill bit, a drill bushing, an actuation device, and a resilient member. The motor is disposed within the housing intermediate the opposed ends. The drill bit is operably connected to the motor and is capable of extending from the housing through one end thereof. The drill bushing is operably connected to the housing and defines a bore, where the drill bushing at least partially surrounds the drill bit as the drill bit extends from the housing through the bore. The actuation device is remotely disposed with respect to the housing and is operably connected thereto, wherein the actuation device is capable of causing the motor to rotate the drill bit and is also capable of causing the drill bit to extend from the housing. The resilient member is operably connected between the housing and the motor and is capable of retracting the drill bit into the housing upon deactuation of the actuation device. The housing is generally cylindrical and defines a central axis, wherein the axis is substantially perpendicular to the end of the housing through which the drill bit extends. In addition, at least one of the motor and the drill bit may be axially moveable with respect to the housing to facilitate extension of the drill bit from the housing. Generally, the drill is adapted to drill a hole in a workpiece and a portion of the housing is adapted to collect chip swarf produced by the drill bit as the hole is drilled. The actuation device may operate under, for example, pneumatic control or electrical control, wherein the control causes the motor to rotate the drill bit and also causes the drill bit to extend from the housing. An associated drilling method and apparatus are also provided.

摘要： A feed system for a drill press. The drill press comprises a base for supporting the drill press on a surface, a housing supported on the base and defining an opening, a telescoping spindle assembly positioned for movement relative to the housing along an axis and for rotation about the axis, a motor operable to rotatably drive the spindle assembly, a drive system connected between the motor and the spindle assembly, and a feed system for moving the spindle assembly between a lowered position and a raised position. The feed system is supported by the housing so that a portion of the feed system is exposed through the opening. The drill press also comprises a flexible barrier member to cover the exposed portion of the feed system. The feed system includes a sprocket rotatably supported by the housing and a flexible member movably engaging the sprocket and connected to the spindle assembly such that rotation of the sprocket moves the spindle assembly between the lowered position and the raised position.

摘要： A drilling machine for tapping a pipe includes a rotatable boring bar which is advanced linearly by a ball bearing nut and screw combination, the nut being fixed to the boring bar and the screw being rotated by a power source. The power source is inactivated when the pipe has been tapped, and the fluid pressure in the main will act on the boring bar tending to force it in a reverse direction thereby tending to rotate the screw rapidly in an uncontrolled manner. To prevent this the machine includes a friction brake of special design which automatically restrains reverse rotation of the screw yet is not sufficient to prevent manual reverse rotation of the screw by the operator.
