Embodiment Construction
[0032] FIG. 1 shows a measuring device 100 for simultaneously obtaining the angle of rotation and the displacement position of a suction tube 110 as a fixture of a component for carrying out an assembly process. The suction tube 110 rests on a hollow rod 111 , which is a shaft supported by two bearing parts 115 and 116 . The bearing is configured such that the hollow rod 111 is rotatable about its longitudinal axis and also axially displaceable along its longitudinal axis parallel to the z-direction. In a manner not shown, this shaft is coupled not only to a linear drive for axially displacing the hollow rod 111 but also to a rotary drive for rotating the hollow rod 111 about its longitudinal axis. This hollow rod 111 serves to transmit negative pressure to the suction tube 110 from a vacuum generating device not shown, so that elements can be held pneumatically by the suction tube 110 when a corresponding negative pressure is applied.
[0033] The measuring device 100 also i...
