Abstract: Apparatus (20) and a method for securing a clinch nut (24) to an AHSS sheet (26) as an assembly (22). In one embodiment, a parallel kinematic machine (PKM) (88) sequentially performs the operation, while another embodiment includes a nut ram assembly (112) that attaches clinch nuts (24) to the AHSS sheet (26), and a further embodiment includes a C frame (114) that supports the apparatus and is moved by a robot (130) to sequentially attach clinch nuts (24) to the AHSS sheet (26) at different locations. The attachment of the clinch nuts is performed in a light-safe manner.

Abstract: A method for mechanically joining steel applies a variable clamp force to a stack of sheet metal portions, which include at least one portion of advanced high strength steel (AHSS). The stack is heated to an optimal mechanical joining temperature to preserve the strength and material properties of the stack and to form a mechanical joint with the advanced high strength steel. A tool and system for performing the method, and a joint assembly formed by the method are provided.

Abstract: Apparatus (20, 22) and a method for mechanically joining a steel sheet portion (28 or 32) of advanced high strength steel to a metallic sheet portion (30 or 34) is performed to a light-safe extent by a detector assembly (106) during the mechanical joining that may be clinching, clinch riveting, full-punch riveting or self-piercing riveting.

Abstract: A method and apparatus (20) provide light-safe heating of advanced high strength steel metallic sheet(s) (28 and/or 30) for securement of metallic sheets by flow fasteners (31).

Abstract: A work station (10) and method for joining metallic sheets (12, 14) by a framework (24) that supports and positions a parallel kinematic machine (PKM) (40) including a tripod (46) having struts (48) of adjustable lengths for supporting a punch (52) that cooperates with an anvil (22) to provide clenching or self-piercing riveting that joins the metallic sheets.

Abstract: A vehicle body clinch nut feeder (22) includes a dispensing head (54) having an inlet passage (60) through which oriented clinch nuts (26) are fed single file. The leading clinch nut is moved laterally to between clamping portions (64a, 66a) of a pair of clamp members (64, 66) of a clamp (62) where a second feed actuator (80) subsequently moves the clamped clinch nut downwardly to an opening (78) in a delivery member (76) where a robot end effector (32) receives the clinch nut in preparation for a clinching operation. An alignment mount (58) supports the dispensing head (54) on a support (56) for a horizontal movement in perpendicular horizontal directions to insure alignment of the robot end effector (32) with the clinch nut (26) to be received.

Abstract: Vehicle body assembly line apparatus includes a plurality of work pallets (14) having locators (18) with locator members (36) that are adjustable by a grab member (40) on each at a remote location below a vertical rest surface (37) mounted on each locator member. An adjusting station (16) provides either automatic adjustment of the adjustable locators (18) by one or more robots (52) or manual adjustment of the adjustable locators (18). A sensor (58) senses the location of a positioning target (56) on each locator member (36) at a known location from the vertical rest surface (37) and any locator pin (38) mounted thereon and generates a deviation signal when the positioning is not within a design tolerance. A control (60) readjusts the appropriate locator (18) as necessary to the design tolerance range.
