Embodiment Construction

[0052] The following will refer to Figure 1-6 A first embodiment of the present invention is described. The interchangeable part 1 is in this embodiment a rotatable tool in the form of a face milling cutter, which is suitable for face milling a not shown workpiece surface and which can be attached to a rotatable holding device 2 . The tool and the holding device are rotatable about a common axis of rotation 3 . The tool comprises a tool body with a circular mounting hole 4 which is through hole and coaxial with the axis of rotation, and a plurality of indexable cutting inserts 5 which are mounted in seats of the tool near the end face 6, The edge of the blade protrudes a small distance beyond the end face.

[0053] The holding device 2 is in the form of an adapter in this embodiment, which is provided in the end attached to the tool 1 with a circular mounting shaft 7, a contact surface 8 and two radially extending and diametrically opposed The key groove 9. In the opposit...

Abstract

The invention relates to a fixation arrangement for attachment of an interchangeable part (1) to a retaining device (2). It comprises a generally circular shaft (7), being attached to or integrated with one of the interchangeable part or the retaining device, and a generally circular mounting hole (4) formed in the other of these two, a rotary preventing means (9, 13) to prevent rotation of the interchangeable part and the retaining device in relation to each other, and an actuator (14) for tightening the interchangeable part and the retaining device towards each other in the direction of a centre axis (3) of the shaft. The fixation arrangement also comprises a sleeve (17), which has a wall thickness that is tapering in a direction of a centre axis of the sleeve, such that an outer envelope surface and / or an inner bore of the sleeve is conically shaped in the direction of its centre axis, and which is formed with at least one slit, as well as a conical portion (4'), which is formed on the inner circumference of the mounting hole (4) and / or on the outer circumference of the shaft. The invention also relates to an interchangeable part as well as a lock key.

Description

technical field [0001] The invention relates to a fixing arrangement for attaching an interchangeable component in the form of a machining tool or workpiece to a holding device, the fixing arrangement comprising: [0002] a generally circular shaft attached to or integral with one of the interchangeable parts or the retaining means, and a generally circular mounting hole formed in the other of the two; [0003] anti-rotation means for tangentially securing the interchangeable part and the retaining means and preventing their rotation relative to each other; and [0004] An actuator for fastening the interchangeable part and the retaining means towards each other in the direction of the central axis of the shaft. [0005] The invention also relates to an interchangeable part in the form of a machining tool or workpiece, which can be attached to a holding device by a fixed arrangement. [0006] The invention also relates to a locking key inserted into a keyway for preventing r...
