Abstract:
An apparatus for maintaining constant force engagement between a finishing tool and a workpiece. The apparatus includes a biasing device that can be coupled to a robotic manipulator, and a support arm having a tool holder disposed at one end. The biasing device is actuated by a pressure source to cause the support arm to rotate a finishing tool into engagement with a workpiece. A counterweight disposed on a second end of the support arm offsets the mass of the finishing tool, whereby constant force engagement between the finishing tool and workpiece may be maintained as the finishing tool is articulated to move relative to the workpiece.
Abstract:
An apparatus for maintaining constant force engagement between a finishing tool and a workpiece. The apparatus includes a motor supported on a rotatable base. A tool holder coupled to the motor supports a finishing tool at as point offset from a rotational axis of the base. The apparatus further includes an actuator configured to rotate the base, whereby the finishing tool is caused to engage the workpiece with a constant and known force.
