摘要:
A system for certifying laser projection beam accuracy includes a certification fixture having a test pattern and a color background. The certification fixture is configured so that any portion of the laser projection beam reflected from the color background is reflected with a color contrasting to that of the laser beam or of the test pattern. Contrast can be further enhanced by making the pattern of a material that absorbs the laser beam color. Failure of the test is indicated by the presence of any of the laser beam light reflecting from the background. Passage of the test is indicated by the laser beam striking only the test pattern. A functional test pattern tests for both laser beam width and positioning accuracy. A method is provided to use a calibration test pattern to test laser beam width and length projection accuracy independently of one another.

A method is disclosed for aligning a laser projection device with a subject article. The method comprises the utilization of specially adapted mounts to secure reflective targets to specific geometric features of such a subject article. By mounting the laser target devices to the subject article itself, tooling jigs are not necessary and the targets can be easily positioned at various locations to avoid laser beam obstruction concerns and to ensure accurate alignment.

A method and apparatus for processing a fastener system. A fastener installation tool may be placed on a surface of an object. An elongate structure may be attached to the fastener installation tool and may have a length. A camera may be associated with the fastener installation tool in which the camera may be configured with a focal length corresponding to the length of the elongate structure. The camera also may be configured to capture an image at least a portion of the fastener system when the elongate structure is placed against the surface of the object on which the fastener system is located. The image of the at least a portion of fastener system may be captured.

A system is provided that includes a laser projection apparatus and a fastener installation apparatus. The laser projection apparatus is configured to project an identifier of an instruction set including one or more instructions for installing a fastener or fastener collar on a structure, with the laser projection apparatus being configured to project the identifier onto the structure about a location at which the respective fastener or fastener collar is to be installed. The fastener installation apparatus is configured to capture an image of the projected identifier from the structure, determine the identifier from the captured image, and retrieve the instruction set based on the determined identifier. The fastener installation apparatus includes a tool for installing the respective fastener or fastener collar, and the fastener installation apparatus is configured to program the tool according to the retrieved instruction set.

A device for securely clamping a drill motor to a drill plate in order to drill precisely positioned holes in a workpiece includes an annular mandrel and annular collet concentrically disposed about the cutting element. A first end of the collet includes a plurality of longitudinally extending fingers while the mandrel has a tapered end portion having a larger external diameter than the center cylindrical portion of the mandrel. A pneumatically-actuated piston is also coaxially disposed about the cutting element to extend and retract the mandrel and the collet. Once extended, the longitudinally extending fingers of the collet overlie the center cylindrical portion of the mandrel. Thus, the clamping device may be inserted through an aperture defined in a drill plate. Following its retraction, the longitudinally extending fingers of the collet overlie the tapered end of the mandrel and are correspondingly expanded. The expanded fingers hook behind the periphery of the aperture defined in the drill plate and securely clamps the drill motor to the drill plate.
摘要:
A method and apparatus for monitoring a pneumatic system. A number of parameters are monitored using a monitoring device connected to the pneumatic system, an energy harvesting unit configured to generate electrical energy from a gas in the pneumatic system, and a controller. The monitoring device comprises a number of sensors configured to detect the number of parameters. The controller is in communication with the number of sensors and the energy harvesting unit and is configured to process measurements for the number of parameters detected by the number of sensors and control operation of the energy harvesting unit. The number of sensors and the controller are powered by the energy harvesting unit. The monitoring device is powered using the electrical energy generated by the energy harvesting unit.
