Patent number: 6962068Abstract: A system is disclosed for installing an insert within an aperture in a workpiece, the workpiece having a first side and a second side. The insert is the type in which a portion of the insert plastically deforms on the second side of the workpiece upon application of a linear force provided by a tool, thereby preventing withdrawal of the insert from the aperture. The insert comprises a sleeve member and an integral flange, where the flange has a larger diameter than the aperture. The disclosed installation system performs two actions. It causes the expansion of the sleeve and it also causes the flange of the insert to be fused or welded to the first side of the workpiece. The welded connection between the insert and the workpiece prevents any rotation or spinning of the insert within the workpiece, and increases the integrity of the insert-fastener connection.Type: GrantFiled: October 31, 2003Date of Patent: November 8, 2005Assignee: AVK Industrial ProductsInventor: Ramon C. Villanueva

Patent number: 6298533Abstract: A disc cartridge assembling apparatus in which a protuberance formed on the inner surface of one of cartridge halves of a thermoplastic resin making up a main cartridge body unit is passed through a through-hole formed in the other cartridge half in register with the protuberance, and in which the distal end of the protuberance is thermally deformed to interconnect the cartridge halves. The upper and lower cartridge halves are stacked together, with a protuberance formed on the upper cartridge half being passed through the through-hole formed in the upper cartridge half, and are held by a holding mechanism. In this state, the distal end of the protuberance is thermally deformed by a caulking head, heated by a heater, and which is provided with a recess in its surface adapted to compress against the protuberance.

Patent number: 6240613Abstract: A rivet setting tool is provided with a cycle control whereby a pressure switch or pressure transducer enables the electronic logic controller to monitor tool hydraulic pressure. When the pressure reaches a predetermined threshold and subsequently drops below a second threshold valve the controller deduces that a rivet has been set and removes pressure from the tool so that the tool can be immediately reset, thus reducing the tools cycle time. Upon determining that a rivet has been set, a mandrel collection window is set. The controller monitors whether a mandrel is returned to the mandrel collection system prior to the expiration of the timed window, and if not, the controller provides a fault signal to the operator. Multiple windows are utilized so that more than one mandrel can be in the return tube at one time without delaying operation of rivet setting system. The pressure sensors can also be utilized to confirm that a rivet has been loaded into the rivet setting tool without the use of a rivet sensor.Type: GrantFiled: November 11, 1998Date of Patent: June 5, 2001Assignee: Emhart Inc.Inventors: Bill O'Connor, James M.
