SELF-PIERCING RIVETTING MACHINE

摘要

A riveting apparatus comprises a portable riveting assembly which may be hand held or mounted on a robot arm. The assembly comprises a C-frame having an anvil mounted on one arm and a hydraulic ram mounted on the other arm. Rivets are supplied to a head assembly located between the anvil and piston rod via a flexible tube having a T-shaped cross-section. After a rivet has been supplied it is held positively in position ready for setting within pocket members by air pressure supplied along tube. Thus, the assembly can be moved rapidly and used in various orientations without displacing the rivet. Connections between the assembly and rivet supply and hydraulic power source are by way of flexible connections.
