Abstract
A machine tool comprises a tool carrier, e.g. in the form of a turret disc (7) that is provided with receptacles (8) for tool holders (9), wherein each tool holder and tool carrier comprise support surfaces associated to each other and devices for fixing the tool holder at the tool carrier. At least one clamping element is provided at the tool carrier (7) that is adjustably supported between a clamping position and a release position in a direction transverse to a tie rod of a tool holder arranged on a slider (22) receptacle of the tool carrier. The clamping element is provided with a first clamping surface (24) that can be brought into engagement with a second clamping surface (35) at the tie rod of the tool holder in a self-locking and releasable manner.
Claims12
A tool holder, comprising:
- a support surface (18) configured to abut a support surface of a tool carrier (7) and devices for attachment to the tool carrier,
- wherein the devices for attachment to the tool carrier comprise at least one tie rod (19) extending orthogonal to the support surface of the tool holder that is configured for cooperation with a clamping device assigned to the tool carrier,
- wherein the at least one tie rod (19) is at least in a section of its length axially elastically deformable and is provided with at least one clamping surface (35) extending orthogonal to a longitudinal axis of the at least one tie rod and that is configured for self-locking cooperation with an assigned clamping surface (24) of a clamping element (22) that is movably supported in the tool carrier (7).
