    Abstract: A clamping device has an actuator that moves linearly and is actuated by a drive. A pivoting clamping element is operatively connected, via a toggle lever mechanism, with the actuator. The toggle lever mechanism includes a drive-side adapter and a hand lever-side adapter. The drive side adapter and hand lever side adapter can be adjusted relative to one another to define an opening angle of the clamping element. One of the adapters has a profiled bar extending in a direction of actuation. The other adapter has an insertion region to accommodate the bar. A fixing element is provided in one of the adaptors to define the location of the adapters relative to one another. The fixing element can be clamped against the profiled bar and also against an insertion region.

  • Publication number: 20150123332
    Abstract: A welding clamp system using a fixture plate with a bulkhead that allows the clamp system to be coupled to a robotic arm. The robotic arm supplies air and electricity through pneumatic and electrical ports, enabling operation of the clamp system. The air is routed to pneumatic cylinders, which power a pneumatic clamp mechanism that moves sliding clamp fixtures along tracks. The sliding clamp fixtures press a work piece against immobile clamp fixtures, allowing a work piece to be secured and held during welding. Presence of a work piece is detected by proximity sensors which are mounted into the fixture. The clamp system allows a robotic arm to grab a work piece from a supply area, initiate and complete welding of the work piece, and then release the work piece onto a discharge station for removal of the completed work piece.

  • Patent number: 8967034
    Abstract: The invention relates to an energy-efficient apparatus driven by compressed air and equipped with a dual piston function for tensioning, or clamping, or centering, or punching, or welding, or clinching, for use in body construction in the automotive industry. The apparatus is driven by a pressurized fluid, in particular by compressed air. It is shown how a significant amount of operating costs can be saved while, at the same time, conserving the environment and consuming a low amount of pressurized fluid, in particular compressed air. In addition, the pivoting angle of a toggle joint assembly and thus of an apparatus connected thereto, for example, a tensioning arm of a toggle tensioning apparatus, can be continuously adjusted in both directions while, at the same time, adjusting a sampling device using sensors, for example, microswitches, or inductive switches, or pneumatic switches, or limit switches.

  • Patent number: 8905817
    Abstract: An air-actuated clamping assembly that is quickly actuated to secure a workpiece in place during machining operations, such as on a waterjet machine. The clamping operation is completed within seconds after a workpiece is placed (for example, when used in conjunction with a waterjet machine) onto the waterjet machine slats. The system greatly minimizes set-up time, allows for an adjustable clamping force, allows for one operator to set up workpieces, keeps the workpiece firmly in place and prevents movement during the machining process, is adaptable to various waterjet brands and models, and is air-actuated so that typical “house air” can be utilized.
