The present invention relates to an alignment device (100) for adjusting a workpiece (400) on a machine table (300) of a numerically controlled machine tool (1000), the alignment device (100) comprises: a lower plate (20) which can be mounted on the machine table (300) of the machine tool (1000), an upper plate (10) which is movably arranged on the lower plate (20), on the upper side of which a workpiece carrier (200) can be mounted, an adjusting mechanism which is arranged between the lower plate (20) and the upper plate (10) for adjusting the relative position of the upper plate (10) to the lower plate (20), and a locking mechanism for securing the relative position of the upper plate (10) to the lower plate (20).

A clamping device for an adjustable stop of a processing machine for guiding workpieces through the processing machine is provided with at least one clamping part that clamps the stop against at least one counter stop. The clamping part is provided on a transmission element, wherein the transmission element is acted upon with a force (F.sub.1) that is converted into a clamping force (F.sub.2) acting upon the clamping part. A release unit is provided for releasing the clamping action. The transmission element is a two-armed lever, one arm of which is acted upon with the force (F.sub.1) in the form of a compressive force and the other arm of which generates the clamping force (F.sub.2).

A lockout unit coupled to a gate to provide selective access to an electrical machine is provided. The lockout unit includes a stationary bracket, an arm, and a removable bracket. The stationary bracket includes a first aperture defined therein, and the arm includes a second aperture defined therein. The arm is selectively movable between an open position in which the arm is spaced from the stationary bracket, and a closed position in which the second aperture is substantially concentrically-aligned with the first aperture to receive a locking device therethrough. The removable bracket is selectively coupleable to the arm when the arm is in the closed position. The removable bracket includes a third aperture defined therein that is selectively aligned with one of the first aperture and the second aperture to receive the locking device therethrough when the removable bracket is coupled to the arm.

The present application relates to a machining assembly comprising an effector intended to be mounted on a robot with multiple degrees of freedom, in which invention the mounting of the motor spindle relative to the intermediate supports and frame of the effector allows a numerically controlled movement along three axes X, Y, Z of a trihedron, the effector bearing on the piece to be machined or on the surrounding tools by means of a ball joint at the foot end of the effector. Since the effector bears on the piece to be machined or on the surrounding tools it is possible to create local stiffness and to obtain the precision required to guarantee the quality of the machining process.
