Abstract
A mobile device for machining a workpiece, the mobile device including a shaft rotatable about a rotation axis; a carriage rotatable with the shaft about the rotation axis and axially, or radially displaceable relative to the rotation axis; a tool support for a cutting tool, the tool support connected to the carriage and displaceable along a carriage axis and in a direction perpendicular to the carriage axis; and a transmission that couples the shaft to the tool support and the carriage so that the tool support is displaceable along a path that includes an axial and a radial movement component relative to the shaft.
Claims4
A mobile device for machining a workpiece, the mobile device comprising:
- a shaft rotatable about a rotation axis corresponding to an axis of the workpiece;
- a carriage supported on the shaft and axially guided in an axial groove of the shaft, the carriage is rotatably fixed to the shaft and axially displaceable along the rotation axis;
- a tool support for a cutting tool, the tool support connected to the carriage by a linear support, the linear support includes a first support rod arranged on one radial side of the shaft and a second support rod arranged on an opposite radial side of the shaft, each of the first and second support rods is supported within a respective through hole in the carriage, the tool support is attached to a respective first end of the first and second support rods, an opposing respective second end of each of the first and second support rods is attached to a support plate, and the tool support is displaceable relative to the carriage in a direction perpendicular to the rotation axis;
- a mechanical continuous transmission includes the linear support, a first transmission arm arranged on the one radial side of the shaft and mounted on the first support rod, a second transmission arm arranged on the opposite radial side of the shaft and mounted on the second support rod, a first connection lever, and a second connection lever;
- and
- a support block rotatably fixed to the shaft, the carriage is movable axially along the shaft relative to the support block,
- wherein each of the first connection lever and the second connection lever is pivotably connected at a respective first end to the support block, the first connection lever is pivotably connected at a second end to the first transmission arm, and the second connection lever is pivotably connected at a second end to the second transmission arm, and
- wherein any axial movement of the carriage along the shaft causes a radial movement of the tool support perpendicular to the shaft via the linear support such that the cutting tool is moved in a curved path.
