  • Publication number: 20150068003
    Abstract: The rivet gun has a barrel, a handle, an inflator, a piston assembly and at least one buffer device. The piston assembly has a piston rod and a piston head. The at least one buffer device is mounted in the piston head and has a housing, a valve stem and a buffer spring. The housing has an inserting hole and a side hole communicating with the inserting hole. The inserting hole has a valve opening. The valve stem is movably mounted in the valve opening. A valve part is formed on a lower end of the valve stem to selectively close the valve opening. The buffer spring is mounted around the valve stem. When the piston head moves upward, the buffer spring absorbs some momentum produced by the high pressure gas to mitigate shake caused by the high pressure gas directly hitting the piston head.

  • Patent number: 7331205
    Abstract: A rivet monitoring system is provided which has a micro-strain or micro fluid pressure sensor that measures strains or pressures within a tool component. These measured signals are compared to a number of tolerance bands formed about median strain or pressure versus time curve. Various techniques are provided to analyze the measured data with respect to the tolerance bands to determine if a particular rivet set is acceptable.

    Abstract: A vehicle body clinch nut feeder (22) includes a dispensing head (54) having an inlet passage (60) through which oriented clinch nuts (26) are fed single file. The leading clinch nut is moved laterally to between a pair of clamp members (64, 66) of a clamp (62) where a second feed actuator (80) subsequently moves the clamped clinch nut downwardly to an opening (78) in a delivery member (76) where a robot end effector (32) receives the clinch nut in preparation for a clinching operation. An alignment mount (58) supports the dispensing head (54) on a support (56) for a horizontal movement in perpendicular horizontal directions to insure alignment of the robot end effector (32) with the clinch nut (26) to be received.

  • Patent number: 7062843
    Abstract: The present invention relates to a straight type riveting gun, which comprises a gun body having a pipe body and a tube body, a front gun pipe, and a back cover, wherein the front gun pipe is locked to front end of the pipe body and the back cover is locked to the tail end of the tube body. The tube body is provided for receiving a rivet-ejecting adaptor of an oil pressure rod. A trigger is mounted at the tail end of the pipe body for pushing a trigger ejector rod. The trigger ejector rod moves a valve to allow the exterior gas to enter a gas-collecting room for forcing a pneumatic piston to perform movement by use of air pressure. The oil pressure rod pushes the oil liquid to allow the riveting rod to generate powerful pulling force instantaneously thereby completing the riveting operation.
