1. A mount for a welding gun for connecting the welding gun to an arm of a welding robot having a first connector for forming a connection with the robot arm and a second connector for forming a connection with the welding gun and having at least one articulated joint provided between two rigid elements of the mount such that the joint is pivotable around a first axis of rotation and locked in a swivel position, wherein the articulated joint is formed having a sleeve that is fixable to a first of the two rigid elements, said sleeve having an inner diameter and an outer diameter, and having a first bore with an inner diameter on the second of the rigid elements, wherein the sleeve is inserted into the first bore and the inner diameter of the first bore and the outer diameter of the sleeve are selected in such a way that the second rigid element is turnable with the first bore relative to the sleeve, wherein a first expansion element displaceable in the longitudinal direction of the sleeve is provided in the interior of the sleeve, which expansion element has a central opening, through which a tensioning bolt is passed, said bolt having a threaded section with an external thread and a bolt head, which abuts the first expansion element at a front end of the central opening, and wherein a support element is provided having an internal thread that corresponds to the external thread for the screwed mounting of the threaded section of the tensioning bolt, wherein screwing the tensioning bolt into the support element causes an expansion of the sleeve and thus causes the sleeve to be seized around the circumference thereof in the first bore, and wherein a means of release that works in conjunction with a stop is provided in order to neutralize an expansion of the sleeve and the seizing of the sleeve around the circumference thereof in the first bore that was triggered thereby. |
