An actuator in the housing is moved by the trigger as it approaches its inward position to activate the cylinder and slam the impact head downward to close the fastener. In a modification the cylinder is replaced by a solenoid.

  • Patent number: 5385041
    Abstract: A ram assembly for riveting apparatus. The piston rod is stabilized for close tolerance or minimum lateral deviation at the work point by linear bearings which ride on an elongate stabilizer bar and are mounted on an elongate member which is in turn rigidly attached to the piston rod for movement therewith, the lateral deviation of the piston rod being controlled by the orientation of the stabilizer bar. This allows a stabilizing piston rod portion to be eliminated so that the space length-wise taken up by the ram assembly may be reduced.

  • Patent number: 5323946
    Abstract: A tool for setting blind rivets. The load of the motor which drives the pulling head between fully forward and retracted positions is monitored. When the pulling head is displaced to set a rivet motor direction will be changed if a moderate load is not sensed in a short period of time or if following such sensing of a moderate load the sensed low drops to a minimum value. When the pulling head is displaced in the opposite direction a stop will be engaged at the fully forward position and the sensing of a moderate load will stop the motor.

  • Patent number: 5279024
    Abstract: The apparatus includes a riveting assembly (10) which includes a rivet die (18) having a concave configuration which is brought into contact with one end of a rivet to be upset. The die (18) is driven into a rivet end by a rivet ram (16) a first time, resulting in an interference fit between the rivet shank and the part being riveted. When the die (18) is withdrawn, the newly formed rivet head will in some instances expand outwardly away from the surface of the part, leaving a gap between the formed end of the rivet and the part. A second strike assembly includes an L-shaped second strike element (28) which is moved between the die (18) and the rivet head. The ram (16) is then driven a second time, forcing the second strike element (28) against the formed end of the rivet, forcing the formed end of the rivet to flow outwardly and toward the part, resulting in the filling of the gap between the rivet head and the surface of the part.

  • Patent number: 5199624
    Abstract: A rivet pulling head is supported for vertical displacement from an up position to a down riveting position. A rivet delivery device is carried by a movable support and has a delivery arm which can be lowered relative to the pulling head and pivoted underneath it to deliver the next rivet to the pulling head. The delivery device is operated when the head is at the up position and while the head is maintained at that location.

  • Patent number: 4967947
    Abstract: A machine comprising a horizontally elongated base having pairs of pylons slidably mounted on opposite sides of the base for horizontal movement along the length thereof, forming in effect, a moveable C-frame. The workpiece is fixedly supported on the base in a substantially vertical position, and the pylons of each pair work together on opposite sides of the workpiece to process rivets/fasteners or perform other functions. Each of the pylons comprises a vertical first component and a horizontal second component. The second component is movable vertically on the first component, and is also movable horizontally toward and away from the workpiece. Carried on the end of each of the horizontal second components adjacent the workpiece is a tool assembly holder that is rotatable about horizontal and vertical axes.

  • Patent number: 4897000
    Abstract: An apparatus for countersinking rivet holes preformed at circumferential spacings in the fuselage of an airplane and in annular reinforcing ribs of H-shaped cross section in the fuselage at axial spacings. Included is a carrier arm cantilevered to a frame for insertion in the fuselage and reinforcing ribs. The carrier arm has a fluid-actuated cylinder and a fluid motor. The cylinder has a piston rod to which is coupled an offset anvil assembly for pressing the fuselage and a rib against a toolhead mounted to the frame. The piston rod, together with the anvil assembly thereon, is not only linearly displaceable but also rotatable about its own axis. The fluid motor actuates the piston rod for revolving the anvil assembly through an angle of at least 180 degrees. With such angular displacement of the anvil assembly, the apparatus is readily adaptable for countersinking two annular rows of rivet holes formed in those parts of the outer flange of each rib which are on the opposite sides of its web.

  • Patent number: 4885836
    Abstract: Improved process and apparatus for assembling component parts by means of rivets or similar fasteners in which computer controlled robotic machining centers present selected tools in predetermined special position on opposing sides of the components which are held stationary in a fixture. The robots prepare the rivet holes at multiple selected locations, followed by repositioning of roboticly controlled tools at each hole location for the installation of the fasteners. Throughout hole preparation and fastener installation novel end effectors maintain a symmetrical balance of forces on the components in a manner which avoids stressing and deformation of the components, holding fixture and end assembly.
