PCT No. PCT/SE89/00685 Sec. 371 Date May 17, 1991 Sec. 102(e) Date May 17, 1991 PCT Filed Nov. 24, 1989 PCT Pub. No. WO90/06214 PCT Pub. Date Jun. 14, 1990.The present invention relates to an arrangement for bringing the tool-carrying end (2) of a robot beam (4) to one desired position of a plurality of possible, predetermined positions, and a workpiece-supporting table-assembly for use with a robot beam steered by the arrangement. The beam-positioning arrangement comprises two beam-holding devices (5, 6) which are intended to support the beam (4) at given mutually-space locations along its length and which are journalled to the beam at the aforementioned locations. At least one of the beam-holding devices (6) is slideably mounted for movement along a first elongated beam-positioning arm (10) and one end of the first arm is pivotally connected to a stand (12) which is moveable along a fixed path. The arrangement is such that pivotal movement of the first arm (10) and movement of the at least one holding-device (6) along its arm will result in a commensurate change in the positional setting of the tool-carrying end of the beam. |
