  • Patent number: 6161992
    Abstract: A machining system has a frame forming a working station and a mounting plate movable relative to the frame in and adjacent the station in a first main direction, in a second direction transverse to the main direction, and in a third direction transverse to the first and second directions. A machine tool head is mounted on the mounting plate and a plurality of struts have outer ends swiveled on the mounting plate and extending inward away from the plate. A mechanism acting on the struts moves the plate and tool head in the three directions. A main panel is movable only in the first and second directions and the head is mounted in the panel for movement relative thereto only in the third direction. In addition a pair of side panels of changeable length each have an inner edge connected along a respective inner axis parallel to the third direction to a respective outer edge of the main panel and a respective outer edge connected at a respective outer axis parallel to the third direction on the frame.

  • Patent number: 6089800
    Abstract: The present invention concerns a protective cover for the sliding guides of a mobile machine tool part and comprises a set of rigid panels which overlap and are guided in such a way that they slide parallel with the machine tool guides, and panel pulling means, designed so that, when a first, driven panel is moved, they allow the subsequent panels in the set to be pulled. The pulling means comprise a pulling element, attached to the first panel, parallel with a direction transversal to the set of planes upon which the subsequent panels in the set lie; and contact faces, on the subsequent panels, opposite the pulling element. The contact faces are positioned in the path of the pulling element at different positions, longitudinal to the guides, so that each is intercepted by the pulling element at a different time as the element moves, thus allowing all of the subsequent panels in the set to be pulled.

  • Patent number: 5807043
    Abstract: A machine tool way cover to provide protection to a moveable machine tool which is provided with an interlocking feature to prevent misalignment or skewing of the actual way cover. The present invention provides a dramatic improvement over prior art machine tool coverings and way covers in that it eliminates the need for individual segments of the machine tool way cover to be manufactured to extremely tight physical tolerances by providing interlocking channels at the base of each way cover segment. The channels provide grooves within which the channels of smaller segments actually move as the machine tool and machine tool way cover move in and out. By providing such an interlocking mechanism, the machine tool way cover avoids becoming misaligned and inoperative even when objects or personnel impart substantial loads to the way cover.

    Abstract: A moving slide has a pair of flexible curtains mounted to its front and rear surfaces, the curtains being attached at opposite ends to front and rear support posts mounted to a base. The support posts have upper and lower pulleys. A cable is connected to the front of the slide and runs in this fashion: first horizontally across the top pulley, thence to the lower pulley, thence to the other support post, thence upwardly and finally around to the horizontal portion which connects to the rear of the slide. The cable is tensioned to a predetermined load which remains constant throughout the slide travel as the front and rear horizontal portions of the cable move. The flexible curtains are suspended from, but are not rigidly attached to, the cable. Thus, as the curtains expand and contract, the moving horizontal portions of the tensioned cable ride smoothly through the curtains, maintaining curtain support.
