Document Type and Number:
Japanese Patent JP3422794
Kind Code:
B2
Abstract:
A machine for simultaneously turning and boring a ring-shaped workpiece has a frame of four parallel structural shafts secured between end stands. An active spindle assembly is mounted on a carriage slidably mounted on the shafts. The carriage is hydraulically drivable axially toward a stop cylinder of a passive spindle assembly rotatably mounted but axially immovable on one stand, to clamp the workpiece ring between a clamp cylinder of the active spindle assembly and the stop cylinder. The clamp cylinder is rotatable by the main machine drive motor for turning the workpiece. The workpiece ring is introduced laterally to the working area by a loader shuttle. Then the workpiece is centered in the work space by an axially drivable centering crescent as the workpiece is clamped in position between the clamp cylinder and stop cylinder for the turning to commence. Cylindrical slides and slideways are provided at right angles for both radial and axial movement of the external turning tool mounting bar. Cylindrical slides at right angles to each other are also provided for radial and axial movement of a boring bar. The finished workpiece moves into a gage which simultaneously measures the inside diameter with a pyramidal plug, and the outside diameter between a stop and a wedge, the wedge and plug being operated by linear actuators driving rotary encoders providing signals useful in a computer for control of the slide drive screws for automatic adjustment if and as needed in response to measured deviations from a standard.
