  • Patent number: 8746665
    Abstract: The invention relates to a drive apparatus (10) for the linear movement of a processing tool with respect to a workpiece, having a tool holder (18) which is fixed on a carriage (16) and is intended for the fastening of the processing tool, having a stationary guide device (12) in which the carriage (16) is guided such that it can be displaced in a vertically linear manner, and having a drive device (42) with a first force transmission means (46) which, in an engaged position, engages with a second force transmission means (40) connected to the carriage (16) in order to move the carriage (16). According to the invention, it is provided that the drive device (42) is mounted in the guide device (12) such that it can be moved between a release position, in which the force transmission means (40, 46) do not engage with one another, and the engaged position in such a way that the gravitational force of the drive device (42) causes a movement from the release position into the engaged position.

  • Patent number: 8511644
    Abstract: Device that uses the force of one or several persons to help a stuck vehicle get free. It comprises a set of chains of blocks (2) to put in front of the wheels and that are connected by straps (3.6) to a system that will pull them under the wheels while pushing the car by reaction. The forces come from a lever system consisting of a main bar with a triangular part fixed underneath and near its front end. When the operator lifts the bar, the displacement of the extremities of the triangular part away from the wheels creates a pull on the straps while the front end of the bar pushes the car. The blocks become the fulcrum of this lever system. Alternately, a winch fixed on the car bumper pulls on the straps via deviation rollers or rings, transmitting the reaction pushing forces to the car rear part.

  • Patent number: 8132802
    Abstract: An apparatus for quickly retaining and releasing parts having a wide range of sizes and designs at an optical measurement station is provided. The apparatus includes a rod having proximal and distal ends. The apparatus further includes a part-engaging first tip attached to the distal end of the rod to move therewith. The apparatus still further includes a part-engaging second tip. The apparatus includes a support structure for supporting the second tip and the rod. The apparatus further includes a quick-release, clamping mechanism for adjustably and releasably clamping the rod to the support structure so that the rod can move the first tip between a part-release position in which a part held between the tips is released for removal from the station and a part-retaining position in which a part is firmly held between the tips. Held parts having a wide range of sizes and designs can be optically measured at the station.

  • Patent number: 8091875
    Abstract: A gripping jig for assembling whereby a force is applied to a molded body in a direction perpendicular to an assembling direction. When an assembling load is applied to the molded body, the force is adjustable with an adjustment screw such that the molded body is guided to move in the assembling direction. Since the force is applied from a direction different from the assembling direction, the molded body can move in the assembling direction, and since the force is adjustable, application of the assembling load to the molded body and the movement of the molded body can be adjusted. Since a plurality of the molded bodies are fixed and assembled respectively, when there are variations in size of the molded bodies, an excessive assembling load is is avoided with each molded body guided to move, so that a more uniform assembling load is applied to the plurality of molded bodies.

  • Patent number: 8006361
    Abstract: An installation tool for use with a liner sleeve attachment, such as a nutplate assembly for mounting onto a substrate blind side as disclosed in U.S. Pat. No. 5,704,747. The installation tool includes retractable grip jaws for gripping and pulling a fixture pin protruding from the attachment, for initially advancing a tapered tool nose piece into deforming engagement with an attachment liner sleeve leading end to flare and/or expand the liner sleeve to lock the liner sleeve onto the substrate. Continued pulling action exerts a sufficient force to collapse a fixture pin head and thereby permit pull-removal of the fixture pin from the attachment. The nose piece is carried by a retractable inner housing normally retained in an advanced position for deforming the liner sleeve, and thereafter movable to a retracted position spaced from the liner sleeve to accommodate substantially unobstructed fixture pin separation from the attachment.

  • Patent number: 7937803
    Abstract: A vacuum bag hold-down arrangement for a dust collection system maintains a negative pressure in the space between a dust collection drum and a plastic film liner or bag in the drum. A cyclonic separator at the station separates the dust from an air flow and deposits it into the liner in the drum. The hold-down arrangement employs a vacuum pump producing about 1 to 3 psig negative pressure. A vacuum conduit extends from the pump through a penetration in the drum and into the space between wall of the drum and the liner bag. A porous pad, e.g., open cell foam, is situated over the vacuum conduit and separates the bag liner from the vacuum conduit. This distributes the air flow into the vacuum conduit and creates a more uniform grip of the liner or bag to the drum.
