Abstract
A mobile machine tool for segmentally machining, in situ, a component, in particular a component of a turbine, which is rotatable about an axis of rotation. The machine tool has a main body, a support element which is held on the main body so as to be movable about a C-axis along a circular-arc-shaped guide path, and a tool module which is held on the support element and is designed to receive a tool. The tool module is located on the support element so as to be linearly movable. A method segmentally machines, in-situ, a component which is mounted in a stationary body so as to be rotatable about an axis of rotation.
Claims21
A mobile machine tool for segmentally machining, in situ, a component which is rotatable about an axis of rotation, comprising:
- a base body, on which fastening means are provided for releasably mounting the base body on a body which is stationary relative to the axis of rotation and which defines the axis of rotation,
- a carrier element, which is held on the base body so as to be movable about a C axis along a circular-arc-shaped guide path, and
- a tool module, which is held on the carrier element and is designed to receive a tool, wherein the tool module is arranged on the carrier element so as to be linearly adjustable transversely, and
- a linear guide to guide the tool module radially with respect to the C axis relative to the carrier element.
A method for segmentally machining, in situ, a component mounted so as to be rotatable about an axis of rotation in a stationary body, comprising:
- a) providing a machine tool which is designed to machine the component over a circumferential segment, and mounting the machine tool on the stationary body, wherein the machine tool comprises:
- a base body, on which fastening means are provided for releasably mounting the base body on a body which is stationary relative to the axis of rotation and which defines the axis of rotation,
- a carrier element, which is held on the base body so as to be movable about a C axis along a circular-arc-shaped guide path, and
- a tool module, which is held on the carrier element and is designed to receive a tool, wherein the tool module is arranged on the carrier element so as to be linearly adjustable transversely;
- b) machining a first circumferential segment of the component using the machine tool;
- c) rotating the component about its axis of rotation by a predetermined angle;
- d) machining a further circumferential segment of the component using the machine tool;
- e) repeating steps c) and d) until the component has been machined over its entire circumference;
- wherein the component to be machined is a component of a turbine, and the stationary body is a turbine housing or a part thereof;
- wherein during normal operation, the component of a turbine is connected in a fixed manner to the housing and is decoupled from the housing before machining and is coupled to a rotor or to the central shaft of the turbine for conjoint rotation therewith;
- and/or
- wherein the stationary body is a housing half of the turbine housing and the machine tool is mounted on a parting plane that rests against the other housing half during operation.
A method for segmentally machining, in situ, a component mounted so as to be rotatable about an axis of rotation in a stationary body, comprising:
- a) providing a machine tool which is designed to machine the component over a circumferential segment, and mounting the machine tool on the stationary body, wherein the machine tool comprises:
- a base body, on which fastening means are provided for releasably mounting the base body on a body which is stationary relative to the axis of rotation and which defines the axis of rotation,
- a carrier element, which is held on the base body so as to be movable about a C axis along a circular-arc-shaped guide path, and
- a tool module, which is held on the carrier element and is designed to receive a tool, wherein the tool module is arranged on the carrier element so as to be linearly adjustable transversely;
- b) machining a first circumferential segment of the component using the machine tool;
- c) rotating the component about its axis of rotation by a predetermined angle;
- d) machining a further circumferential segment of the component using the machine tool;
- e) repeating steps c) and d) until the component has been machined over its entire circumference;
- and
- wherein during machining, an axial, annularly encircling projection formed on the component is shortened.
