Title: AUTOMATED RING CRIMPING METHOD AND GUN FOR IMPLEMENTING SAME
Abstract:
The invention aims to avoid the handling of rings to be crimped before they are fitted onto rivet shanks, by incorporating safe dispensing of the crimping rings onto these shanks. To this end, automated positioning of the rings upstream of the compression tube is provided. In a preferred embodiment, a crimping gun (2) according to the invention has a ring compression tube (22) of longitudinal axis (X'X) and a handle (21) for grasping and controlling this tube (22), and a ring positioning module (3) made up of a base (31) for securing to said tube (22), a frame (32) movably connected to the base (31) by a system for moving along an axis parallel to the longitudinal axis (X'X) of said tube (22) from a starting position, and a ring transporting gripper (33) movably connected to the frame (32) by the system for moving along a main axis (Y'Y) perpendicular to the longitudinal axis of the tube. Said gripper (33) has a housing for receiving a ring to be crimped (12) such that this housing is located in a position aligned with the compression tube (22) following the movement along two axes (X'X, Y'Y) carried out by the system for moving.
