  • Publication number: 20140373673
    Abstract: A machine tool has a telescopic cover. One end of the telescopic cover is fixed to the machine tool via a cover supporting member. In the cover supporting member, through holes through which fixing bolts pass are formed on a surface to be fixed to the telescopic cover and a surface to be attached to the machine tool. Gaps between the through holes and fixing bolts are used to adjust the attachment position of the cover supporting member with respect to the machine tool and the position of the telescopic cover with respect to the cover supporting member.

    Abstract: A fixing member has such a shape that members that constitute a telescopic cover can be fixed and immovable. The fixing member is secured to the telescopic cover by means of fastening members such as bolts. The fixing member of a telescopic-cover fixture is shaped so that the telescopic cover is maximally contracted when the fixing member is secured to the cover. For example, the fixing member may be L-shaped, U-shaped, or in the shape of a rectangular tube that covers the entire cover member.

Each tab may define a peripheral extremity of the body, extending outwardly thereof and situated substantially within the same plane as the body. Each tab may have a particular width, and may include a neck defined by a fillet having a predetermined radius, both tab width and fillet radius being sized and configured to absorb load forces through elastic deformation. As such, the tabs may elastically deform under load to minimize any deformation of the planar body of the device, which in the disclosed embodiment may be formed of an elastic metal plate. Each tab may have the same thickness as the planar body, and both the tabs and the planar body of the device may comprise the same material.

    Abstract: The present invention provides a concave part cover that can be easily inserted and be safely secured in a concave part even if tolerances and dimensional errors of the concave part such as a slot or a hole, and of the concave part cover for covering the concave part are large. The concave part cover comprises: a top plate 11 for covering the concave part; and a pair of pressing parts 12A and 12B extending from the top plate 11 and pressing side walls 52A and 52B of the concave part when the pressing parts 12A and 12B are inserted into the concave part. Base ends 15A and 15B of the pressing parts 12A and 12B are positioned at the top plate 11 in such a manner that a distance between the base ends 15A and 15B is shorter than distance W (between the side walls 52A and 52B), and portions of extending parts 16A and 16B of the pressing parts 12A and 12B are formed to project outwards until they are spaced at a wider distance therebetween than the distance W.

  • Patent number: 6668901
    Abstract: A connecting device rotatably joins a protective plate to a bellows that covers the guide of an automatic machine, machine tool or robot. The plate is one of a plurality of partially overlapping protective plates that slide and turn relative to each other as the bellows is extended and compressed. The connecting device includes a pushing element designed to extend freely through an aperture made in the respective plate and to come into contact with an outside face of the plate itself; a joining element which can be stably connected to the bellows at a respective transversal fold line and which is designed to come into contact with an inside face of the respective plate so as to rotatably support the plate in removable, pivot-like fashion when the plate is pushed by the pushing element; and a pair of helical springs forming a single component with the pushing element and stably connected to the joining element.

  • Patent number: 6662685
    Abstract: A splash cover is assembled to a mount of a base. A space for holding a packing is provided between the splash cover and the mount. A packing port is provided to the accommodating space. The structure allows an operator to install or remove the packing to or from the accommodating portion inside the splash cover without interference from the splash cover. Thus, installing or removing the packing can be easily performed. In addition, because the packing is invisible from outside, the appearance of the splash cover is improved.

  • Patent number: 6658966
    Abstract: A work bench includes a frame, a bench surface on the frame with the bench surface including at least two members, one of which is movable along the frame for clamping a workpiece between the members. A mechanism for moving the member includes two screws coupled with the members. The two screws are spaced with the member for moving the member upon rotation of the screws. A sprocket is coupled with each of the screws. A transmission belt or chain is coupled with the sprockets. At least one handle is coupled with one of the screws to rotate the screws. At least one clutch is coupled with the at least one screw to limit clamping pressure on the workpiece. The clutch enables rotation of one screw with respect to the other screw so that workpieces may be clamped between the members and clamping of the workpiece may be accomplished by rotation of the screws with one hand of the operator. Also, a guard may be present which covers the transmission belt or chain.

  • Patent number: 6485088
    Abstract: Disclosed is a sheathing material for a construction machine and a method for producing the same, in which lightweighting can be attained without using a reinforcing member, and which is not greatly flexed even if a load is applied. The sheathing material for a construction machine which is lightweighted and has a flexure rigidity is obtained by molding a resined shell 1d having a hollow construction by rotational molding, filling a resin foamed body 1e such as a hard polyurethane foam within the resined shell 1d to set it, thereby providing a sandwiching construction, and adjusting filling density of the resin foamed body 1e.
