Tool changing device for a machine tool and manufacturing system

A tool changing device for a machine tool, comprising:

• a handling unit comprising a handling robot,
• an interchangeable tool magazine, and
• a provisioning site for the tool magazine,
• wherein the handling unit comprises a tool gripper for gripping tools,
• wherein the tool magazine is configured as an upright disk magazine with a vertical rotation axis,
• wherein the tool magazine is detachably mounted at the provisioning site on a rotary table that is rotatable to provide a desired rotational position of the tool magazine for a tool change in which a selected tool location in the tool magazine is accessible for the tool gripper of the handling unit,
• wherein the handling unit is adapted to change tools between the tool magazine and a tool holder in a workspace of the machine tool,
• wherein the handling unit and the tool magazine are arranged in a setup cell that is arranged to be coupled to the workspace of the machine tool via a closable setup interface,
• wherein the handling robot is adapted to move the tool gripper through the setup interface into the workspace to change tools there,
• wherein the rotary table has a bearing surface,
• wherein the tool magazine has a support surface,
• wherein the tool magazine rests with the support surface on the bearing surface, and
• wherein the support surface is spaced along a longitudinal extension of the tool magazine by at least 30% of the longitudinal extension from a lower end of the tool magazine.

A manufacturing system for machining workpieces, comprising:

• at least one machine tool that is configured for multi-axis machining, and which has a tool holder and a workpiece holder, which can be moved relative to one another in at least three axes,
• wherein the tool holder and the workpiece holder are arranged at a rear side of a workspace of the machine tool, and
• a tool changing device, comprising:
• a handling unit comprising a handling robot,
• an interchangeable tool magazine, and
• a provisioning site for the tool magazine,
• wherein the handling unit comprises a tool gripper for gripping tools,
• wherein the tool magazine is configured as an upright disk magazine with a vertical rotation axis,
• wherein the tool magazine is detachably mounted at the provisioning site on a rotary table that is rotatable to provide a desired rotational position of the tool magazine for a tool change in which a selected tool location in the tool magazine is accessible for the tool gripper of the handling unit,
• wherein the handling unit is adapted to change tools between the tool magazine and a tool holder in a workspace of the machine tool,
• wherein the handling unit and the tool magazine are arranged in a setup cell, which is arranged to be coupled to the workspace of the machine tool via a closable setup interface, and
• wherein the handling robot is adapted to move the tool gripper through the setup interface into the workspace to change tools there,
• wherein the tool magazine has in the region of its upper side at least one receiving space for a workpiece fixture for workpiece fixation on a workpiece holder of the machine tool, and
• wherein the at least one workpiece fixture is transferable by the handling robot with a fixture gripper between the setup cell and the workspace.
