Abstract
The invention relates to a head for positioning a tool on irregular surfaces, formed by a tool-holder assembly which is coupled to a robot arm (4) by means of a support (3), the tool-holder assembly being provided with a force sensor (2) and distance detectors (7) by means of which a control of the action of the robot arm (4) for positioning the work tool with respect to the operating surface is established.
Claims4
A head for positioning a tool on irregular surfaces, for performing a robotic tracking of a work tool on irregular surfaces comprising a tool-holder assembly having a support for coupling to a robot arm, said tool-holder assembly being provided with a force sensor and distance detectors, by means of which a control determining the positioning of the work tool with respect to the operating surface is established,
- wherein the tool-holder assembly has a tool-holder plate which is attached by means of the force sensor with respect to the support for coupling to the robot arm, the tool-holder plate centrally incorporating a ball joint and a distribution of distance detectors arranged around it, a disk-tool being attached to the ball joint, which disk-tool is adapted to the working surface due to the play afforded by the mentioned ball joint, varying the force and position of the thrust thereof on the working surface by means of the robot arm according to the information provided by the force sensor and distance detectors.
A head for positioning a tool on irregular surfaces, comprising a tool-holder assembly having a support for coupling to a robot arm, said tool-holder assembly being provided with distance detectors mounted on the support, by means of which a control determining the positioning of the work tool with respect to the operating surface is established, wherein a tool separated by a distance from the working surface can be directly incorporated on the support for coupling to the robot arm, distance detectors by means of which a control with respect to the corresponding working surface is determined being arranged on the support in order to place the tool perpendicular to the working surface and at a constant distance.
A head for positioning a tool on irregular surfaces, for performing a robotic tracking of a work tool on irregular surfaces comprising a tool-holder assembly having a support for coupling to a robot arm, said tool-holder assembly being provided with a force sensor and distance detectors, by means of which a control determining the positioning of the work tool with respect to the operating surface is established, wherein the tool-holder assembly has a tool-holder plate on which multiple disk tools are incorporated, said tool-holder plate being attached in articulation with respect to the support for coupling to the robot arm and supported on an actuator cylinder operating to correct the position of the mentioned tool-holder plate, according to the distribution of the supporting force of the different disk-tools on the working surface.
