Abstract: The invention concerns an industrial robot (4) comprising a machining tool (2) attached to one hand (3) of the robot, designed to perform a hydraulic-driven movement relative to the hand (3) and connected therefor to a hydraulic unit (10). The hydraulic unit (10) is placed directly on a mobile part of the robot, in particular directly on the robot hand (3). Therefore there is no more need for hydraulic supply lines along the arm of the robot. Further, when the robot hand (3) changes tool, no separation of hydraulic lines is required. The machining tool (2) is in particular a device for placing blind rivets, thereby enabling an entirely automated process for placing blind rivets.

Abstract: A compensating unit for a tool unit for inserting an element into a workpiece, in particular a setting unit for inserting a joining element into a workpiece. The tool unit is fastened to a mounting and being mounted, oriented in an axial direction, in such a way that, during the machining operation, a compensating movement in a plane oriented at least approximately perpendicular to the axial direction is made possible.

Abstract: A feeding unit for feeding an element to a treatment unit of a machine tool, in particular for feeding a rivet to a riveting unit, has a gripping element provided for the fastening element for the automatic take-up of the fastening element from a supply unit and automatic feed to the treatment unit. The gripping element is disposed on a rotary element rotatable about an axial direction, and at least one electromagnet is provided which is configured in such a way that a torque acting on the rotary element is generated by a magnetic force.

Abstract: An hydraulic unit provides a pressurized hydraulic fluid at an outlet. The unit has an electric motor and a pump operated by the motor for generating pressure. A reservoir having a variable compensation volume stores the hydraulic fluid primed by the pump in a gas-free manner. The hydraulic fluid is especially pressurized in order to safely and reliably guarantee that the hydraulic fluid is gas-free. The inventive design allows for the safe and operationally reliable use of the hydraulic unit even at high acceleration values. The hydraulic unit is especially adapted for use in an industrial robot.
