Abstract
The invention relates to a device for machining and/or conveying materials, comprising a roller element rotatably supported about a longitudinal axis, at least one tool holder, a support element for supporting a cutting tool and a cutting tool, wherein the tool holder includes a receiver in which the support element is received in a form locking manner and the support element includes a bore hole. In order to configure the support element that is provided for holding the cutting tool engaging the material so that it can be exchanged in a much simpler manner it is proposed to arrange the fixation element coaxial with the support element, wherein the fixation element is connected with the support element through a threaded connection.
Claims17
A device comprising a roller element rotatably supported about a longitudinal axis, at least one tool holder, a support element for supporting a cutting tool and a cutting tool,
- wherein the tool holder includes a receiver receiving the support element in a form locking manner and the support element includes a bore hole,
- wherein a fixation element is connected in a force transferring manner with the support element through a threaded connection,
- wherein the fixation element is arranged coaxial with the support element,
- wherein the support element and also the fixation element respectively include a support portion,
- wherein each of the support portions protrudes in a radial direction beyond the receiver of the tool holder and is supported with a support surface of the respective support portion,
- wherein the support surface is respectively oriented towards the tool holder and supported at a respective corresponding support surface of the tool holder,
- wherein the support portion of the fixation element is formable by a safety ring that is removable without destruction, and
- wherein the safety ring is supported in a circumferential groove of the fixation element.
A method for mounting a support element for supporting a cutting tool of a device, the device comprising a roller element rotatably supported about its longitudinal axis, at least one tool holder including a receiver, the support element including a bore hole, a fixation element and at least one cutting tool, wherein the method includes steps of:
- a) connecting the at least one tool holder with the roller element;
- b) arranging the support element and the fixation element individually in the receiver of the at least one tool holder;
- c) threadably engaging the support element with the fixation element;
- and
- d) inserting an assembly tool for bolts from a top side of the tool holder through the bore hole of the support element into a bore hole of the fixation element providing form locking engagement therewith configured to transfer torque between the assembly tool for bolts and the fixation element.
A device comprising a roller element rotatably supported about a longitudinal axis, at least one tool holder, a support element for supporting a cutting tool and a cutting tool,
- wherein the tool holder includes a receiver receiving the support element in a form locking manner and the support element includes a bore hole,
- wherein a fixation element is connected in a force transferring manner with the support element through a threaded connection,
- wherein the fixation element is arranged coaxial with the support element,
- wherein the tool holder is made from a base holder and a change holder, and
- wherein the change holder is disengageably connected with the base holder and furthermore includes the receiver for receiving the support element in a form locking manner.
