Abstract
A workpiece change for use in a machine tool that comprises a tool spindle for clamping tools for machining workpieces, comprises two wheels arranged parallel to one another and rotatable about an axis of rotation into at least two prominent angular positions. Two swivel tables for clamping workpieces are arranged between the wheels and are each mounted on the wheels to swivel about a swivel axis which runs parallel to the axis of rotation. In each prominent angular position, one of the swivel tables is located in its working position in which clamped workpieces can be machined with the tools. Both wheels are supported at their rim.
Claims18
A workpiece changer for use in a machine tool that comprises a tool spindle for clamping tools for machining workpieces, said workpiece changer comprising:
- two wheels which are arranged parallel to one another and which are rotatable about an axis of rotation into at least a first angular position and a second angular position, said two wheels being supported at their respective rims, and
- at least two swivel tables for clamping respective workpieces, the at least two swivel tables being arranged between said two wheels and each being mounted on said two wheels such as to swivel about a respective swivel axis that runs parallel to the axis of rotation, and for each of the at least two swivel tables a respective window is provided in at least one of the two wheels, each window enabling visual inspection of the associated swivel table,
- wherein in each of the first angular position and the second angular position one of the at least two swivel tables is located in a working position in which the respective workpieces clamped thereto are machined with the tools.
A machine tool comprising a tool spindle for clamping tools for machining of workpieces, and a workpiece changer, said workpiece changer comprising:
- two wheels which are arranged parallel to one another and which are rotatable about an axis of rotation into at least a first angular position and a second angular position, said two wheels being supported at their respective rims, and
- at least two swivel tables for clamping respective workpieces, the at least two swivel tables being arranged between said two wheels and each being mounted on said two wheels such as to swivel about a respective swivel axis that runs parallel to the axis of rotation, and for each of the at least two swivel tables a respective window is provided in at least one of the two wheels, each window enabling visual inspection of the respective swivel table,
- wherein in each of the first angular position and the second angular position one of the at least two swivel tables is located in a working position in which the respective workpieces clamped thereto are machined with the tools, and
- wherein an indexing device is provided and associated with at least one of said two wheels for fixing the at least one of said two wheels, which is associated with the indexing device, in the first and second angular positions.
