A shaft supporting mechanism of an industrial robot in which an arm is supported by a freely extendable support shaft inside a hollow post and a working plane of a working arm is variably set is provided, with plural sets of linear support guides in opposed relation about a drive mechanism of the support shaft. As a result, the support shaft is held in the post stably and balanced in the vertical direction even if an external force attempting to tilt the support shaft is applied during up-and-down movement of the support shaft or operation of the working...
A shaft supporting mechanism of an industrial robot in which an arm is supported by a freely extendable support shaft inside a hollow post and a working plane of the arm is variably set, comprising: (a) a drive mechanism positioned outside said support shaft for driving said support shaft to extend and retract the same vertically; (b) a plurality of guide seats connected to said support shaft, arranged at positions substantially laterally symmetrical with respect to said drive mechanism and each having an opening; and (c) a corresponding plurality of lin...
