摘要:
Un porte-outil pour des outils de coupe multiples est pourvu d'un dispositif a came (46) permettant le reglage precis de la position d'au moins l'un des outils (36) (par exemple un outil d'equarrissage en bout) par rapport a un autre outil (38) (un outil a chanfreiner). Le porte-outil est particulierement adapte pour etre utilise avec un tour portatif ayant un mandrin (60) s'etendant en travers du porte-outil.

Provided is a cutting edge adjustment device capable of readily adjusting the position of a cutting edge with high accuracy by the use of a rotary member such as a cam. For this purpose, a cutting edge adjustment device (1) for a cutting tool for adjusting the position of a cutting edge of a cutting insert (4) by causing movement of the cutting insert (4) includes a rotary member (5) for producing the movement. The rotary member (5) is formed into a shape in which a substantially cylindrical portion (17, 18) having a constant radius and a cam portion (19) having a cam face whose radius is gradually increased in a manner corresponding to the amount of the movement are arranged in a direction of a rotational center axis (O). The cam face is formed in such a manner as to have a section in which a radius is linearly increased, and consequently, the unit rotational angle of the rotary member (5) on the rotational center axis is proportional to the unit movement amount of the cutting insert (4).

A clamping mechanism clamps a cutting insert in a tool body. The clamping mechanism has a clamping arm seated within a clamping arm pocket. The clamping arm includes a clamping protrusion extending rearwardly from a rear surface of the clamping arm. The cutting insert has a bore having an insert retaining surface and is seated within an insert pocket. Upon tightening the clamping arm into the tool body, the clamping protrusion presses against the insert retaining surface and the cutting insert is securely abutted within the insert pocket.

A tool holder (10) which is convertible to perform a veriety of machining operations such as threading, turning and grooving comprises a support bar (12) formed with a cavity which receives a mounting block (24) having a seat (32) adapted to support an insert so that the top surface of the insert is exposed and its cutting edge extends outwardly from the seat. The insert is clamped within the seat by a clamping block (48), which is secured atop the insert by a machine screw (26). The top edge of the clamping block is formed with a beveled bearing surface (64) which engages the head of the machine screw so that forces are applied to the clamping block upon tightening of the screw which urge the insert downwardly, rearwardly and inwardly against the walls of the mounting block seat.

The invention relates to a modular tool system consisting of a tool holder (10) with a fitting for a cutting insert holder (11) which, when released, is radially movable in relation to the tool holder by means of an adjusting screw (17) fitted in a threaded hole (16) in one of the holders and can be clamped with the tool holder by means of clamping screws (15). To provide an alternative radial adjustment of the tools or centred fitting without facilities for readjustment without a great deal of effort, the stop is a pin (18, 30) releasably securable in the holder, whereby at least one diameter of the pin is the same as that of the pin recess in the other holder and the blind hole in the first holder (20, 29), into which the projecting end of the pin enters and the hold for the adjusting screw opens perpendicularly thereto.
