Plural Parallel Beams Patents (Class 269/148)
  • Patent number: 10792775
    Abstract: The invention relates to a method and machining device for clamping and machining a control cabinet component in a machining device. The method includes the following steps: Arranging a workpiece configured as a control cabinet component on a work surface of a machining device; clamping the workpiece on the work surface, wherein a supporting unit with at least one clamping device arranged on it, is shifted to an edge of the workpiece using an actuator-driven shifting unit and a clamping element of the at least one clamping device is shifted from a released position to a clamped position when guided towards the edge of the workpiece, meaning that the clamping element comes to rest at multiple contact points on the workpiece so that the clamping element secures the workpiece in a machining position, preventing it from shifting perpendicularly to the work surface, and machining the workpiece using a machining tool.

  • Patent number: 5544872
    Abstract: Apparatus for clamping and orienting work relative to a tool, for processing, comprising, in combination two laterally extending longitudinally separated support bars, and connector means connected to and extending between the bars for positioning them in fixed separated condition, there being work receiving space between the bars; bar leveling means extending downwardly from the bars for supporting the bars on a support bed, the means being adjustable to adjust the leveling of the bars; and work clamping pistons carried by the bars for hydraulically actuated movement toward the work receiving space for engaging and clamping the work to hold the work in fixed position relative to the bed.

  • Patent number: 5421384
    Abstract: An unlimited width dovetailing system for holding a workpiece and guiding a router while cutting dovetails in an upper edge of the workpiece includes a base plate with a pair of blocks attached thereto, and a beam which rests on the base plate, abutting against the blocks. A dovetail template for a router is affixed to the beam, which can be turned end-for-end to expose either side of the template to the workpiece.An overhead clamping mechanism for holding the workpiece in a vertical plane against a front face of the beam includes a pair of bars each having a fixed jaw pivotally bearing against a respective one of said blocks and having an offset which extends over the workpiece's upper edge, a pair of movable jaws, one on each of the bars, an elongate clamping member extending between the jaws, and a pair of clamping screws, each passing through a threaded hole in its respective jaw and into said elongate member.
