Patent number: 7877850Abstract: A method is provided for precisely positioning and joining first and second sheet panels. A first hole is extruded in the first panel with an annular upstanding wall surrounding the first hole. The first hole has a diameter to fit closely over the locating pin of a support. A second hole is formed in the second panel and has a diameter to fit closely over the annular upstanding wall of the first panel. A bond is created between the first and second panels adjacent to the annular upstanding wall, so that the annular upstanding wall protects the locating pin from being fouled by the bonding material. The bond may be either an adhesive bond or an electric resistance weld or both an adhesive bond and an electric resistance weld and the annular upstanding wall acts as a dam to protect the locating pin from the adhesive or weld splatter.Type: GrantFiled: March 27, 2007Date of Patent: February 1, 2011Assignee: GM Global Technology Operations LLCInventors: Pei-Chung Wang, Roland J.

Patent number: 7856704Abstract: A monitoring device monitors an apparatus that clinches together sheet metal panels. In particular, a die assembly positioned on one side of the panels has a button forming die cavity defined by an anvil at the bottom of the die cavity and a plurality of radially moveably die blades at the side of the cavity. A plunger is positioned on the other side of the panels and registers with the die assembly so that linear displacement of the plunger plastically deforms the panels axially into the die assembly to engage with the anvil and then further linear displacement of the plunger will then deform the panels radially outward as permitted by the outward radial movement of the moveable die blades. Transducers measure the linear displacement of the plunger, the radial outward displacement of the radially moveable die blades, and the magnitude of the axial force applied against the anvil.Type: GrantFiled: October 14, 2005Date of Patent: December 28, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Pei-Chung Wang, James W.

Publication number: 20090297316Abstract: An integrated vacuum and magnetic gripper includes a rigid housing defining an internal chamber, and a flexible vacuum cup operatively connected thereto. A vacuum cavity is defined by the vacuum cup and a vacuum source is configured to reduce pressure in the vacuum cavity. A permanent magnet is disposed within the rigid housing, and a magnet release mechanism is configured to selectively render the magnet incapable of exerting sufficient force to hold the work piece. A pole plate may be interposed between the internal chamber and vacuum cavity, such that the pole plate forms a portion of the internal chamber and may act to provide friction on the work piece. A method of using the gripped includes operating at high acceleration while the vacuum gripper is monitored as fully operational and operating only at lower acceleration while the vacuum gripper is not fully operational.Type: ApplicationFiled: May 30, 2008Publication date: December 3, 2009Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: James W.

Patent number: 7313851Abstract: Apparatus is provided for monitoring the installation of a blind rivet to attach together top and bottom members. The blind rivet installation tool includes a housing having an anvil seated on the rivet head. A collet is reciprocable within the tool housing and carries jaws for gripping the mandrel of the blind rivet. Retraction of the jaws by the collet displaces the jaws and the mandrel axially and causes the mandrel head to axially collapse and radially expand the hollow shank of the blind rivet into engagement with the bottom member so that the rivet attaches the top member and the bottom member. A first transducer measures the axial load imposed on the mandrel. A second transducer measures the axial displacement of the collet and the jaws and the mandrel.Type: GrantFiled: January 27, 2006Date of Patent: January 1, 2008Assignee: GM Global Technology Operations, Inc.Inventors: Pei-Chung Wang, James W.

Patent number: 4091795Abstract: A cooking adapter structured to rest on the top of a gas fired lantern, and to make use of the heat generated by that lantern for cooking purposes. The lantern's top is in the form of a hat-shaped structure having heat exhaust ports in the crown portion thereof. In preferred form, the cooking adapter includes a cylindrical tube having a grid fixed in place transverse to the axis of the sleeve at a location about midway between the ends of the sleeve. The bottom half of the sleeve is provided with an annular insulated wall, the grid being supported on that annular wall. The sleeve's insulated wall portion is sized to cooperate with the crown and brim portions of the lantern's top to support the sleeve on that top in spaced relation to the heat exhaust ports in the top's crown portion. In use, the cooking adapter is simply seated on top the gas fired lantern, a cooking implement then being placed on the grid to expose that implement to the heat which exhausts through the lantern top's heat exhaust ports.Type: GrantFiled: September 3, 1976Date of Patent: May 30, 1978Inventor: James W.
