Abstract
A reduction of a bend of a drill during processing is achieved. A drilling device includes: a spindle for rotating a drill so that the drill processes an object; a parallel link mechanism configured to adjust a direction of the spindle; a force sensor configured to detect a moment from the object and about an axis perpendicular to an axial direction of the spindle while the object is processed; and a control section configured to control the parallel link mechanism on the basis of the moment detected by the force sensor so that the parallel link mechanism adjusts a direction of the spindle.
Claims8
A drilling device comprising:
- a spindle for rotating a drill so that the drill processes an object;
- a parallel link mechanism configured to adjust a direction of the spindle;
- a force sensor configured to detect a moment which is applied to the spindle and is about an axis perpendicular to an axial direction of the spindle;
- a control section configured to control the parallel link mechanism on a basis of the moment detected by the force sensor so that the parallel link mechanism adjusts the direction of the spindle;
- a holding section for holding the spindle such that the spindle is rotatable,
- the parallel link mechanism comprising:
- a first stage fixed to the holding section;
- a second stage opposite to the first stage;
- a plurality of links connecting the first stage and the second stage in such a manner as to each have a degree of freedom;
- and
- a driving part configured to drive the plurality of links.
