The invention relates to a hydraulic device for driving an actuator to be hydraulically controlled or actuated, comprising a motor arranged in a motor housing, a compensating tank () for accommodating hydraulic fluid, and a hydraulic pump, which is arranged in a pump housing and driven by the motor, wherein the hydraulic pump is designed in such a way that the hydraulic pump permits conveyance of hydraulic fluid in two directions, namely in the forward direction and in the backward direction.

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

Robot hand and method for automatically placing an element

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.

Compensating unit for a tool unit and method for inserting an element into a workpiece

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.
