  • Patent number: 6543121
    Abstract: Riveting apparatus wherein a planetary roller screw delivers the high forces required for actuating the fastener upset tooling. In order that precise control of the entire upset operation may be obtained, a servo-controlled electric motor operates the actuator. In order that different machining operations may be performed on a workpiece without having to provide an actuator for each tool, the tools are engaged in turn by the actuator for performing riveting and other machining in succession.

  • Patent number: 6427312
    Abstract: A control system and method for automatic fastening machines wherein a multi-axes motion controller is utilized in place of the conventional PLC or CNC control to provide for virtually an immediate change in system response when the systems feedback devices indicate the need for variance. The major advantage of the process control approach of the present invention is that all system feedback information is controlled via a single on board processor thus eliminating any communication lag associated with multi controller applications. This also provides for an improvement in fastener installation cycle time. An additional advantage to the approach of the present invention is the elimination of many mechanical hard stops and their respective electrical position switch indicators, which in turn reduces the chance for machine breakdowns resulting in a greater increase in productivity.

  • Patent number: 6295710
    Abstract: An automatic fastening machine and method which reduces fastener installation cycle time by virtue of unique tool movements, pressure foot operation and other features. The pressure foot plate is coupled to actuators for moving the same in a manner allowing tilting of the plate relative to the plane of the workpiece during movement from one fastener installation location to another. The actuators are independently operated by a servo control arrangement in conjunction with the machine control. As a result, it is not necessary for the system to seek a new down position thereby saving machine cycle time. Sensors operatively associated with the actuators in conjunction with the machine control cause movement of the pressure foot plate in reaction to force applied to the workpiece during fastener installation to maintain the workline established by the position of the workpiece prior to application of force.

  • Patent number: 5680003
    Abstract: An improved coiled-coil filament for use in an incandescent lamp has a primary coil winding with a substantially uniform spacing between successive coil turns. The primary coil winding is wound around a second mandrel in a manner to provide a main coil body and leg portions extending therefrom. A helical bend is formed between the main coil body and the leg portions thereby allowing that the leg portions extend toward a seal region of the lamp envelope in a substantially parallel relation to each other. Once the main coil body has been set in shape, the first and second mandrels are removed such that the leg portions are disposed in the seal region of the lamp envelope in a spaceless, and optional spudless manner.

  • Patent number: 5661892
    Abstract: The present invention provides a method and apparatus for positioning tooling with respect to a curvilinear workpiece which is curved in a first direction extending along a plane substantially perpendicular to the longitudinal axis of the workpiece and which is curved in a second direction extending along a plane to the workpiece longitudinal axis, the degree of curvature in the first direction being greater than the degree of curvature in the second direction. An illustrative example is automatic drilling, inserting and upsetting one or two piece fasteners such as exterior skin rivets on an airplane fuselage. Inner and outer positioning systems carry or support inner and outer tooling, respectively, which engage the workpiece from opposite sides thereof during tooling operations thereon.

  • Patent number: 5222289
    Abstract: A method and apparatus (10) for fastening upper and lower workpieces (20, 22) without movement of the workpieces. The apparatus is provided with a frame having upper and lower portions (24.1, 24.2) carrying upper and lower riveting ram assemblies (26, 28), respectively. Each riveting ram assembly includes a buck ram (30 or 32), a buck ram moving assembly (62 or 90, 92), a pressure foot (34 or 36), a pressure foot moving assembly (38 or 40), a buck ram position measuring device (74 or 104), and a pressure foot position measuring device (78 or 108). The upper pressure foot moving assembly (38) further includes an upper pressure foot compensation cylinder assembly (42). The apparatus also includes a load cell (112) carried by one of the buck rams for sending a force signal in response to the force being applied to the fastener during upset and thereafter.

  • Patent number: 5060362
    Abstract: A method and apparatus for riveting two workpieces (20, 22) together by simultaneously upsetting both ends of a slug rivet (12). The present apparatus includes a frame portion (44) which may deflect during the rivet upsetting operation and a frame compensation booster assembly (164) which is provided to ensure that movement of the upper riveting ram relative to the frame portion (44) is increased an amount equal to the frame deflection so that the workpieces will be maintained in a substantially fixed work plane during the upsetting operation. Before the slug rivet is upset and after the slug rivet has been snugly engaged by the riveting rams (50, 60) the pressure behind the riveting rams is equalized by introducing fluid into the cylinder (48) until the pressure within the cylinder (48) equals the pressure within the cylinder (56). This is to prevent movement of the workpiece at the commencement of the upsetting operation.

  • Patent number: 4864713
    Abstract: A method and apparatus for positioning tooling and riveting the apparatus including a frame provided with opposed riveting rams (96, 86) and clamps (34, 36). The first clamp (34) is extended above the work plane established by the outer surface of one workpiece (10) with the lower ram retracted. Next, the frame (26) is moved downwardly until the first clamp touches the workpiece. An encoder (140) measured the amount of first clamp collapse during overtravel of the frame after the first touch is sensed. The frame is now backed off this distance to establish a work line coextensive with the work plane. The lower clamp (36) is then raised to clamp the workpieces (10, 12) and drill carried by a sub-frame (66) will now drill aligned apertures through the workpieces. The subframe is indexed to another position to place rams (96, 86) is alignment with the apertures. The upper riveting ram (96) is then advanced to its full down position to set an upper cavity and is locked under high pressure.
