Abstract
A device (1) for exchanging at least one cutting component (2a) of a rotating tool (2), in particular a milling tool (2), and more particularly, a hollow milling tool for machining workpieces made of plastic. The device has an aligning device (5) for orientating a position of the cutting component (2a) relative to a rotational axis (2c) of the tool (2) and an exchanging device (6) for releasing the cutting component (2a) from a part (2b) that remains on the tool (2) and for attaching another cutting component (2a) to the part (2b) that remains on the tool (2).
Claims11
A device (1) for exchanging at least one cutting component (2a) of a rotary tool (2) for machining workpieces made of plastic, the device comprising:
- an aligning device (5) for rotating the at least one cutting component (2a) about a rotational axis (2c) of the tool (2), and
- an exchanging device (6) for releasing the at least one cutting component (2a) from a body (2b) of the tool (2) and for attaching another cutting component (2a) to the body (2b) of the tool (2);
- wherein the aligning device (5) comprises means (12) for determining an angular position of the tool (2) about the rotational axis (2c),
- wherein the aligning device (5) further comprises a positioning element (10), the positioning element (10) being a tapered wedge that is movable into one of a plurality of openings (11) formed in the at least one cutting component (2a), and
- wherein moving the positioning element (10) into the one of the plurality of openings (11) causes the at least one cutting component (2a) to be rotated into a position about the rotational axis (2c) at which the exchanging device (6) is able to release the at least one cutting component (2a) from the body (2b) of the tool (2).
A device (1) for exchanging at least one cutting component (2a) of a hollow milling tool (2) that rotates about a rotational axis and that machines plastic workpieces, the device comprising:
- an alignment device (5) which engages the at least one cutting component (2a) and which rotates the at least one cutting component (2a) about the rotational axis of the milling tool (2) so as to orient the at least one cutting component (2a) into a desired rotational position;
- and
- an exchanging device (6) that is couplable with the at least one cutting component (2a), the exchanging device (6) being actuatable to remove the at least one cutting component (2a) from a hollow body (2b) of the milling tool (2) and to attach another cutting component (2a) to said hollow body (2b);
- wherein the alignment device (5) comprises a proximity sensor (12) for determining an angular position of the milling tool (2) about the rotational axis (2c),
- wherein the alignment device (5) further comprises a positioning element (10), the positioning element (10) being a tapered wedge that is movable into one of a plurality of openings (11) formed in the at least one cutting component (2a), and
- wherein moving the positioning element (10) into the one of the plurality of openings (11) causes the at least one cutting component (2a) to be rotated into the desired position about the rotational axis (2c), and it is at the desired position where the exchanging device (6) is able to remove the at least one cutting component (2a) from the hollow body (2b).
