| 20120063870 | SYSTEM FOR INJECTING FASTENERS IN THE MANUFACTURE OF AIRCRAFT OR OTHER ASSEMBLIES - The injector assembly receives fasteners such as bolts used in the manufacture of composite aircraft wing structures, at a high speed from a supply thereof, such as a cartridge. The injector assembly includes a post assembly which includes a hollow post housing having a post mass and a mass stop pin positioned within the housing. The bolt moves through a feed tube assembly, a muzzle member and into a chamber portion of the injector assembly. A urethane contact member is positioned at a forward end of the mass. A source of compressed air moves the mass and the contact member into a position slightly past the rear end of the housing and into a chamber portion of the injector assembly. When the bolt contacts the contact member at high speed, the mass is moved back toward a base portion of the post assembly. The mass is sufficient to dissipate the kinetic energy of the moving bolt without damage thereto. | 03-15-2012 |
| 20110113623 | SYSTEM FOR LOADING COLLARS ONTO BOLTS IN LARGE-SCALE MANUFACTURING OPERATIONS - The system includes a collar feed assembly which includes a channel within a step assembly at the end thereof, which defines a receiving cavity for the collar. The receiving cavity is configured so that the collar can move slightly therein, permitting a die portion of a die tool to engage a center opening of the collar, so that the collar can come into accurate alignment with the center axis of the die tool. The die tool is mounted to be movable slightly transversely to permit a reliable transfer of the collar onto the bolt. The collar is more compliant than the die tool during loading of the collar onto the die pin and the die tool is more compliant than the collar during transfer of the collar from the die pin onto the bolt. | 05-19-2011 |
| 20110098852 | ROBOTIC MANUFACTURING SYSTEM WITH ACCURATE CONTROL - A robot mechanism for controlling the position of a machine tool in a large-scale manufacturing assembly includes six rotary axes and one linear axis. Secondary feedback systems are included on at least several of the axes. A controller receives secondary feedback information and uses it to control the position of the machine tool within an accuracy of ±0.3 mm. | 04-28-2011 |
| 20090260413 | SYSTEM FOR LOADING COLLARS ONTO BOLTS IN LARGE-SCALE MANUFACTURING OPERATIONS - The system includes a moving feed assembly through which a collar is moved by compressed air to a position in substantial alignment with the centerline of a swaging die assembly. Two spring-loaded fingers are mounted on opposing sides of the feed assembly for receiving the collar by compressed air action where it is maintained in substantial alignment with the swaging die assembly. The spring action of the fingers is strong enough that the collar can be pressed firmly against a curved receiving portion of the fingers by the compressed air. A die pin portion of the swaging die is then inserted into the collar, thereafter maintaining the position of the collar as the feed assembly with the opposing fingers are stripped away from the collar, leaving the die pin-engaged collar free to be moved by action of a ram assembly to a stackup of parts to be fastened, where the collar can be transferred onto a bolt which extends through the stackup. | 10-22-2009 |
| 20090127279 | RIVET INJECTOR SYSTEM FOR AN AUTOMATIC RIVETING MACHINE - The rivet injector system includes a set of grasping spring-loaded rivet fingers which are mounted on a rivet ram portion of an automatic riveting machine. The rivet injector assembly receives a rivet from a feed tube into a chamber in the assembly. A stopper pin and a moveable forward end stop within the chamber are operated to hold the rivet axially, the rivet being supported on a rivet pad in the chamber. A tower portion of the injector assembly is slidably mounted to raise the rivet, forcing it between the spring-loaded rivet fingers, which firmly grasp the rivet. The forward end stop and the stopper pin are then retracted and the tower portion lowered, leaving the rivet grasped by the rivet fingers, permitting the rivet to be moved forwardly into a hole in the workpiece. | 05-21-2009 |
