Abstract
Abstract An upper fixed plate (3) can have an annular fixed plate (4) attached, where both are disposed at the lower end of a work arm (1) of an industrial robot. A spring-supported receiver disk (5) with an attachment ring (5a) for a gripper (2) can be supported on the upper fixed plate (3) and on the annular fixed plate (4). The upper fixed plate (3) and the annular fixed plate (4) each can have four engagement-catch recesses for ball-shaped locking elements (6). The engagement-catch recesses can be of conical shape and can have an opening angle of about 120 degrees and can have a depth of about 3 mm. In addition, the upper fixed plate (3) can be provided with two centering bores (3c) for motion-limiting pins (9). The motion-limiting pins (9) protrude into the motion-limiting bores (5c) of the spring-supported receiver disk 5. Next to the motion-limiting bores are disposed threaded bores (5b) with a threaded socket ( 7) for the ball-shaped locking element (6). The ball-shaped locking element (6) is pressed with a spring (8) into the engagement-catch recess (4b) of the lower annular fixed plate (4). The locking element (6a), illustrated on the right-hand side of the drawing of FIG. 1, is locked in an engagement-catch recess (3b) of the upper fixed plate (3).
