  • Patent number: 10010964
    Abstract: A mount for connecting a welding gun to a welding robot's arm. An articulated joint is provided between two rigid elements of the mount. The joint includes a sleeve securable to a first element. A first bore is provided on the second element. The sleeve is inserted into the bore. The bore's inner diameter and the sleeve's outer diameter allow the second element to turn with the first bore relative to the sleeve. An expansion element provided in the interior of the sleeve is displaceable in the longitudinal direction of the sleeve. The expansion element has a central opening through which a tensioning bolt is passed. The bolt threadably engages a support element causing expansion of the sleeve, thereby causing the sleeve to seize around the circumference thereof in the bore. The expansion and seizing of the sleeve is neutralized by a release and stop.

  • Patent number: 9945253
    Abstract: A method is provided for operating a laser system. During an embodiment of this method, inert gas is directed against an object within a cavity of a collection device. An aperture is formed in the object by ablating the object with a laser beam that travels within the cavity and to the object. Byproducts of the ablation are removed from the cavity. During another embodiment of the method, inert gas is pooled against an object and a gas curtain is provided proximate a lens. The object is cut using a laser beam which travels from the lens, through the gas curtain and the pooled inert gas, to the object. Fumes and/or particulates produced by the formation are directed away from the laser beam.

  • Patent number: 9931713
    Abstract: Laser systems and methods improve the processing velocity of the routs or other features to avoid exceeding the laser system's dynamic limits. A laser processing system divides laser processing commands corresponding to a plurality of features to be processed on or in the workpiece into process segments. Laser processing parameters and beam trajectories are simulated to determine a maximum processing velocity for each of the process segments. The laser processing system selects one or more of the maximum processing velocities for processing the plurality of features on or within the workpiece. A slowest processing velocity of the maximum processing velocities may be used to process each of the plurality of features. Alternatively, each continuous rout sequence may be processed using a different processing velocity. In other embodiments, each process segment is processed using its corresponding maximum processing velocity.
