<p>The invention relates to a swivel connection intended to be mounted on a robot arm and further intended to carry a welding jaw or something else such as a gripping device. The swivel connection is also intended to have the ability to transfer liquid or gaseous media. It is characterized in that it comprises a rotatable cylindrical hub (6) having an attachment piece (7) at one end for being mounted to a robot arm or the like, a non-rotatable coupling sleeve (10) around the hub (6), a pair of concentric contact rings (12, 13) isolated from each other and from the coupling sleeve and a cover (15) at the other end of the hub (6) around which two from the cover electrically isolated concentric rings (17, 18) are arranged adjacent to the two concentric rings (12, 13) around the coupling sleeve (10). Channels (11) for supply of air and liquid are further arranged in the coupling sleeve (10), the hub (6) and the cover (15) with the rings (17, 18).</p> |
