Abstract: To provide a clamping mechanism, and an apparatus and a method for manufacturing joined object, all of which allow, with a simple configuration, clamping of clamp objects having sizes different from each other, stably at their positions. A clamping mechanism 10 includes a plurality of clamp claws 11 configured to clamp an object S to be clamped; a plurality of support shafts 16 configured to pivotally support a corresponding clamp claw 11, wherein the corresponding clamp claw 11 pivots around the support shaft 16 for opening or closing movement; and a mover apparatus 12 configured to cause the clamp claw 11 to perform the opening or closing movement. A joined object manufacturing apparatus includes the clamping mechanism 10, a holder configured to hold an object to be joined, and a joining apparatus configured to join the object S clamped by the clamping mechanism 10 and the object to be joined that is held by the holder. A method for manufacturing a joined object includes causing the clamping mechanism 10 to clamp the object S by use of the joined object manufacturing apparatus, causing the holder to hold the object to be joined, and joining the both.

Abstract: A securing system, such as a welding system, includes a robot configured to transfer a part to a home position. A securing station has a frame and a gun supported on the frame. The gun includes first and second members movable relative to one another, which are first and second weld gun electrodes, for example. The gun is configured to secure a component to the part in a securing position during a securing operation. A float assembly interconnects the gun to the frame and is configured to permit the gun to glide relative to the welding frame between the home position and the securing position. A homing assembly includes a homing guide configured to release the welding gun from the home position during the securing operation, such as resistance welding fasteners to sheet metal workpieces.

Abstract: To enable a first welding target member including a projection on a welding target portion having short sides and long sides and a second welding target member to be bonded by resistance welding with high welding strength. A manufacturing method for manufacturing a welded article by bonding a first welding target member including an elongated projection portion on a welding target portion having short sides and long sides that are longer than the short sides and a second welding target member by resistance welding, in which the projection portion of the first welding target member is subdivided by forming subdividing grooves extending in the direction of the short sides in the projection portion to reduce the influence of skin effect on the welding current flowing through the subdivided projection portions and improve the uniformity of the current values in the direction of the long sides.

Abstract: A overlapped body 10 comprising steel plates 1a and 1b and satisfying (TS1×t1+TS2×t2)/(t1+t2)≥440 is energized while being sandwiched and pressed by a pair of electrodes 2a and 2b to form a molten pool 4b at a steel plate interface 4 and thereby to join the steel plates 1a and 1b. TS1 represents the tensile strength (MPa) of the steel plate 1a, t1 represents the thickness (mm) of the steel plate 1a, TS2 represents the tensile strength (MPa) of the steel plate 1b, and t2 represents the thickness (mm) of the steel plate 1b. An energization point 4a is formed at the steel plate interface 4, and spot welding is performed such that the molten pool 4b is formed at a position at a horizontal distance W of 20 mm or less from the energization point 4a.

Abstract: Provided is apart stopping/passing unit for apart including a unit main body having a part passage, an opening/closing member configured to open and close the part passage, and an attracting mechanism. The opening/closing member includes a stopper surface for stopping a part and a passing hole for allowing the part to pass therethrough. The attracting mechanism is configured to position the part by an attracting force when the stopper surface takes a part stopping position, and to allow the part to pass by elimination of an attraction force when the passing hole takes a part passing position.

Abstract: In a refrigerant circuit component or valve device, the present invention projection-welds a connector to a cap member and prevents intrusion of spatter into a refrigerant circuit. A-cylinder section in which an inside hole of the connector is open is inserted in an inside hole formed in the center of the cap member. The area between the A-cylinder section and a projection of the connector is used as a spatter generation space. The projection of the connector abuts against the cap member and is projection-welded to form a welded part. The open end of the inside hole of the A-cylinder section is crimped to pressure-join the open end to the open end of the inside hole of the cap member. Spatter is sealed inside the spatter generation space. A portion of the surface layer to which the generated spatter adheres may be removed by machining to provide a spatter-removed structure.
