    摘要: An automatic riveting apparatus is improved by providing at least one sensor on a pressure foot plate or at an interface between the pressure foot plate and a pressure foot bushing of the apparatus for generating a signal indicative of force transmitted between the pressure foot plate and the pressure foot bushing. For example, the at least one sensor may include a strain gauge or other type of sensor for measuring deflection of the pressure foot plate, or it may include load cell(s) for measuring force at the interface between the pressure foot plate and the pressure foot bushing. A control system of the apparatus may be configured to execute one or more control functions based on a value of the sensor signal or signals. The control functions may adjust machine operation commands or trigger a safety mode based at least in part on the sensor signal.

A rail base is provided and the second pair of rails is mounted on the rail base. A third pair of rails that extend in an X-axis direction are mounted to the floor, and the rail base is positioned on the third pair of rails, such that the second pedestal is movable along the third pair of rails in the X-axis direction toward and away from the first pedestal. A first movable carriage is mounted on the first pedestal and a second movable carriage is mounted on the second pedestal. A frame member is supported by the first and second carriages and the frame member holds a workpiece. The first and second carriages are independently movable toward and away from the first and second pairs of rails such that the fixture frame is capable of being raised, lowered and tilted. A C-frame is mounted on the third pair of rails and the C-frame is capable of performing tooling operations on the workpiece.

    摘要: An automatic fastening machine and method which reduces fastener installation cycle time by virtue of unique tool movements, pressure foot operation and other features. The pressure foot plate is coupled to actuators for moving the same in a manner allowing tilting of the plate relative to the plane of the workpiece during movement from one fastener installation location to another. The actuators are independently operated by a servo control arrangement in conjunction with the machine control. As a result, it is not necessary for the system to seek a new down position thereby saving machine cycle time. Sensors operatively associated with the actuators in conjunction with the machine control cause movement of the pressure foot plate in reaction to force applied to the workpiece during fastener installation to maintain the workline established by the position of the workpiece prior to application of force. The clamp of the lower ram is driven positively during both upward and downward strokes so as to save cycle time. The lower ram tool is rotated in a manner which does not interfere with other components on the lower ram assembly. A new and improved slug riveting process also is provided by the machine and method.

    摘要: A method and apparatus for positioning tooling with respect to a curvilinear workpiece which is curved in a first direction extending along a plane substantially perpendicular to the longitudinal axis of the workpiece and which is curved in a second direction extending along a plane substantially parallel to the workpiece longitudinal axis, the degree of curvature in the first direction being greater than the degree of curvature in the second direction. An illustrative example is automatic drilling, inserting and upsetting one or two piece fasteners such as exterior skin rivets on an airplane fuselage. There is provided a head for supporting a plurality of tools at spaced locations around a central axis wherein each of the tools has an operational axis disposed substantially parallel to the central axis and an arrangement for moving the head along paths of travel relative to the workpiece to reach various locations on the workpiece where the tools are to perform operations on the workpiece. The head is rotated about the central axis to selectively position each of the tools at a location where the tool operational axis is in alignment with a work axis of the workpiece so that the tool can operate on the workpiece. In order to achieve finite normalization of the tooling to the workpiece surface, the head is pivoted about a first axis substantially perpendicular to the central axis and substantially perpendicular to the longitudinal axis of the workpiece, and the head is pivoted about a second axis substantially perpendicular to the central axis and substantially parallel to the longitudinal axis of the workpiece.
