Abstract
Automatic welding installation where a robot arm (1) is equipped so as to be able to seize one or other of several torches (20) serving to fulfil different tasks and positioned on a rack (21). Assembly means are provided for ensuring the continuity of all the functions without any external intervention. In particular there are connections for guiding the filler wire (8) and reversibly locking the torches to the assembly face (13) of the arm (1).
Claims25
Automatic welding installation comprising a robot arm (1) provided with a control device (2) and an assembly face (13) for a random number of welding torches (20) provided with an assembly face (47), and a rack (21) provided with stowing locations (23) for the torches (20), the arm (1) comprising a magazine (7) for filler wire (8), a wire advance device (10, 11, 110), a conduit for guiding the wire (8) fixed to the assembly face (13) and a means (63 to 65) for the automatic, reversible locking of each of the torches (20) to the arm (1), the assembly faces of the arm and the torches comprising engaging means (49, 62) having a single assembly position for which, with the assembly faces coupled and the locking completed, the guide conduit of the wire of the locked torch is in the extension of the guide conduit of the arm wire, characterized in that the torches comprise a mobile nose (40) connected to another part (44) of the torches (20), to which belongs the assembly face (47), by a mechanical, distance regulating connection (45), a guide conduit (43) for the wire of the torches constituted by a part (73) fixed to the nose and a part (72) fixed to the other part (44) of the torches, the two parts (72, 73) of the guide conduit sliding in one another.
