Abstract
The invention relates to an industrial robot with a stand (1) which is rotatably journalled in a base (2) and provided with a mechanical stop for limiting the rotary motion of the stand. The stop comprises at least one radially projecting stop arm (7), which in a certain rotational position makes contact with a stop pin (6) arranged on the base (2). The rotary moment is taken up by deformation of the stop pin (6). The stand (1) is provided with a plurality of recesses (8, 10) arranged around the periphery of the stand, whereas the stop arm (7) is formed with at least one fixing projection (12, 13) which is adapted to the recesses and which, with the aid of a wedge member (14), may be fastened into one of the recesses at an optional location on the periphery of the stand.
