Abstract: An apparatus for tightening connecting rod attachment members comprises a rotating mechanism for rotating and positioning a crankshaft about a center of its shaft section, angular deflecting mechanisms for deflecting nut runners about the center of the shaft section, axial displacement mechanisms for displacing the nut runners in an axial direction of the crankshaft, and inter-axis displacement mechanisms for making mutual approach or separation for a distance between the pair of nut runners and a distance between the pair of nut runners. The nut runners are operated to fasten a connecting rod to the crankshaft. Accordingly, one tightening apparatus can be used to tighten the connecting rod attachment members to the crankshaft even when the type of the crankshaft is changed. The tightening apparatus is applicable to a production line for carrying multiple types in a mixed manner.

Abstract: Two metal plates are joined together by curling, where projections are formed in advance at an edge of one of the two metal plates and those projections are forcibly advanced into an edge or the other of the two metal plates so as to interlock the metal plates without any mutual displacement therebetween and not requiring any positioning of projections or cut and raised portions with respect to holes.

Abstract: A first plastic film 90 is prepared which is cut into an effective area V1 constituting a three-dimensional object and a non-required area U1 not constituting the three-dimensional object, and a second plastic film 94 is fed above the first plastic film 90. Meanwhile, a photo-setting adhesive 96 is applied on a lower surface of the second plastic film 94, and a portion 96a corresponding to a sum of the non-required area U1 of the first plastic film and a non-required area U2 of the second plastic film is solidified whereas a residual portion 96b remains non-solid. The non-solid portion 96b is irradiated with a light beam and solidified to attach the first and the second plastic films with each other. The second plastic film 94 is then cut into an effective area V2 and the non-required area U2. The three-dimensional object is formed by successively laminating plastic films through repetition of the above steps.

Abstract: An apparatus is presented for hemming at least two panels together. An inner panel, having a rounded corner, is initially positioned onto an outer panel, also having a rounded corner, the rounded corners of the panels overlapping. The rounded corner of the inner panel is also preliminarily positioned against a rounded, corner hem flange of the outer panel. The apparatus includes a creasing blade, having a concave rounded corner, which is brought toward an external surface of the hem flange. Contact occurs between the outer surface of the hem flange and the concave rounded corner of the creasing blade. The hem flange is then pressured by the rounded corner of the creasing blade, thereby preliminarily folding the outer panel hem flange over the inner panel by an acute angle. The creasing blade is withdrawn form the hem flange. The acutely angled fold of the outer panel hem flange is subsequently pressed by the flat surface of a final folding blade, until the hem flange crimps the inner panel.

Abstract: Automatic alignment correction of the setting angles of mirrors in a laser robot is achieved by mirrors 2c,2d, and 2e being linearly displaced a predetermined distance in a sequence from one closer to a laser oscillator 1 to another. At the same time, a locus of displacement of a spot S on a position sensor during movement of a particular mirror is detected by the position sensor 9 disposed in front of a laser output nozzle 4. An error in the setting angle of a mirror preceding to the particular mirror having been moved is computed on the basis of the detected value, so as to perform angular correction relative to the particular mirror by motors 11a and 11b. In one embodiment, mirror 2e is rotated about the C-axis. When the incident position of the laser beam is offset from the center of rotation of the mirror 2e, the spot S obtained in the position sensor 9 will move in a circular path.

Abstract: A method for hemming at least two panels together begins with the step of positioning an inner panel, having a rounded corner, onto an outer panel, also having a rounded corner, the rounded corners of the panels overlapping. This is followed by a positioning the rounded corner of the inner panel against a rounded, corner hem flange of the outer panel. Next, there is the step of advancing a creasing blade, having a concave rounded corner, toward an external surface of the hem flange. Contact occurs between the outer surface of the hem flange and the concave rounded corner of the creasing blade. The hem flange is then pressured by the rounded corner of the creasing blade, thereby preliminarily folding the outer panel hem flange over the inner panel by an acute angle. The creasing blade is withdrawn from the hem flange. Finally, the acutely angled fold of the outer panel hem flange is subjected to a flat surface of a final folding blade, until the hem flange crimps the inner panel.

Abstract: A method of calibrating a CCD camera comprising those sequential processes comprises steps of shifting a spot light source held by a positioning device, in front of a fixed CCD camera between two remote points on a visual line in order that light beam in the center of the light source can be incident upon predetermined picture element of a solid sensor built in the CCD camera, computing angles between a plurality of visual lines generated by shifting the light source and the optical axis of the CCD camera based on position data related to the positioning device, and calibrating the corresponding relationship between the angle of light beam incident upon the CCD camera and the predetermined picture elements built in the solid sensor.

Abstract: A self-illuminating measurable-point member includes; a light source, a fine through-hole which permits light from the light source to permeate therethrough, and a diffusible member which diffuses light permeating the fine through-hole. Light from the light source is condensed via the fine through-hole and diffused via the diffusible member.

Abstract: A three-dimensional measuring apparatus includes a minimum of a pair of CCD cameras which respectively pick up an image of an objective surface of an objective workpiece requiring dimensional measurement. At least a single unit or a pair of laser scanner sequentially irradiates a plurality of spots on the measurable surface with laser beams. The spots respectively make up measuring points when operating the pair of CCD cameras for measuring dimensions of the objective surface. The laser scanner directly displays the results of the dimensional measurement on the objective surface.

Abstract: A method of measuring three-dimensional dimension of a object comprising the steps of installing two or more than two of CCD cameras, installing a plurality of reference-point members to at least four locations in the periphery of or on a measurable object, installing a reference bar having a known distance between a pair of points thereof, computing positions of respective measurable points based on image data transmitted from those CCD cameras, wherein a computer unit computes absolute positions of those CCD cameras based on horizontal and vertical angles of respective reference-point members and a pair of points of the reference bar against light axes of the installed CCD camera and also based on the distance between a pair of points of the reference bar, and then, the computer unit computes positions of respective measurable points based on processed data as reference. Whenever those image data vary, the computer unit correctively computes absolute positions of the installed CCD cameras.

Abstract: The apparatus according to the invention separates a cam structure which activates operation of a pre-hemming structure used for supporting a blade available for preliminarily folding a hem flange into two units including a lower cam structure used for pressuring a movable member of the pre-hemming structure in the downwardly slant direction corresponding to the preliminary folding direction and an upper cam structure for activating operation of the lower cam structure. After completing the preliminary folding process against the hem flange, the upper cam structure is retracted to permit the lower cam structure to be free from pressuring force transmitted in the preliminary folding direction by the movable member. In consequence, the preliminary folding blade is securely prevented from repeatedly and uselessly being operated on the way of lifting an upper mold after completion of the hemming process.
