ABSTRACT:
A horizontal insert designed for horizontal insertion in a universal turret milling machine, particularly Bridgeport-type milling machine, to facilitate performance of horizontal milling, drilling, boring and tapping operations, as well as standard vertical machining operations, in one setup. The horizontal insert is characterized by a generally cylindrical quill housing designed for insertion between the bottom column element and top ram element of a Bridgeport-type milling machine or secured to a plate so mounted. In the first embodiment the bottom surface of the quill housing is bolted to the top surface of the column and the upper surface of the quill housing is bolted to the bottom surface of the turret. A quill assembly which terminates in a spindle for mounting milling tools, drill chucks, end mills and the like, is manually or automatically horizontally-extendible from the quill housing and a splined end of the spindle is driven by a motor mounted on a top housing which is mounted to the rear surface of the insert. The reversible spindle is selectively coupled by means of a lever to a gear train located in the quill housing, to transmit torsion from the spindle to a feed pinion gear which advances the quill a selected distance from the quill housing to the workpiece, or retracts the quills from the workpiece into the housing. Alternatively, the spindle can be disengaged from the gear train and the quill advanced from or retracted into the quill housing a selected distance by manually rotating a hand feed wheel on the housing. Forward-reverse and speed control mechanisms are also provided for controlling the direction and speed of rotation of the spindle.
