Fixed portal (gantry) for precision coordinate measuring machines

摘要

Portal for a measuring machine, the supports of which between the foundation bed (1) and portal (2) consist of relatively wide metal sheets which allow the traverse an excursion under load only in one direction (Y-direction). Provided between the foundation bed (1) and the portal (2) is at least one reinforcement (40) consisting of two parts which are connected to one another by at least one double-waisted thrust member (12), with the result that the support consisting of metal sheet and reinforcement opposes with a substantial resistance an excursion of the traverse (2) in the Y-direction.
