Axially adjustable tool holder

Abstract

An axially adjustable tool holder, essentially constituted by a principal body (1) with attachment, in a recess (2) of which is slidably mounted a mobile part (3) for mounting a tool (4). The mobile part (3) for mounting a tool (4) cooperates with a ring for transverse adjustment (5), freely mounted in rotation on the extremity of the principal body (1) including the recess (2) for mounting said mobile part (3) for mounting a tool (4), and secured transversely to said extremity, by means of a ball bearing device (8), and presented in the form of a sleeve provided with an interior thread (5′), said ball bearing device (8) presenting axial play guaranteeing, when the mobile part (3) is tightened, application of the proximal face (51) of the adjustment ring (5) against a corresponding distal external supporting flange (1′) of the principal body (1), the mobile part (3) being locked in working position, after adjustment, by means of at least one device for tightening (6) by traction cooperating with a corresponding part (7) of the mobile part (3). The adjustable tool holder is applicable in the domain of manufacture of monobloc, modular or other tool holders used in used in multi-spindle, multi-post machines, for the precisely identical mounting of tools on such machines.
