Boring and facing head

摘要

A boring and facing head, rotatively driven by the mandrel of a machine tool, with a turning tool mounted on a mounting slide, which may be controllably driven transversely of the axis (X) of the head body by a threaded shaft (12) operatively connected to a cylinder body (11), integral with a mandrel (4) and rotatably housing a ring gear (17), operatively connected to a gear wheel (19), driven by a controllable motor (8) and wherein the ring gear (17) comprises a circumferential tooth arrangement engaging with a gear wheel (52), integral with the driving shaft (12).

1. A boring and facing head coupled to a mandrel of a machine tool for rotating a turning tool about a tool axis, comprising:
a slide movable along a transverse axis that is generally perpendicular to the tool axis, the slide having the turning tool mounted thereon for movement along the transverse axis; and a drive assembly for jointly moving the slide and the turning tool, the drive assembly including a drive motor having a motor shaft extending along a shaft axis that is generally parallel to the transverse axis, a first gear wheel mounted on the motor shaft for rotation about the shaft axis, a ring gear in meshing engagement with the first gear wheel for rotation about the tool axis, a threaded shaft extending along the transverse axis, and a second gear wheel fixedly mounted on the threaded shaft and being in meshing engagement with the ring gear for turning the threaded shaft about the transverse axis.
