Abstract

A three-dimensional measurement device, characterized in that it is formed by the conjunction of five elements; a) a base resting on a marble or reference surface, through four height-adjustable pneumatic cushions, which slides along one side of the marble when said base includes a set of adjustable treads in a certain raceway by a rule attached to the marble, the base being linearly displaced by means of two rotating drive wheels, the displacement being joined by means of a nonius related to a rule of precision parallel to the rolling rule; b) a column emergent from the base and solidly joined to it in a normal position, with a tubular section and provided with hardened raceways, there being a stabilizer bar lying between a point of the base away from that and the free end of the column; e) a crosshead that embraces and guides the column, sliding through adjustable position bearings, which includes a housing in which a displaceable arm is guided through adjustable position bearings; d) an arm crossing the crosshead is linearly displaceable along an axis orthogonal to the axes of displacement of the crosshead and base, of mechanized and rectified tubular profile; and e) a head located at the end of the arm to block the measuring, control or plotting tools and built in two half-pieces, one fixed to the arm and another mobile and susceptible to fixation to the previous one, through at least one high-precision circular guide and graduated; existing in one of the external faces of both the column and the arm outside the tracks of a rule of precision in all its length and in the upper part of said column, guiding devices and suspension of the crosshead, being this counterbalanced by a suspended mass, which runs through the inside of the column, automatically blocking the crosshead when the means of suspension fail achieving the lifting and lowering movements, as well as the forward and backward movement of the arm by means of two steering wheels and existing braking means for the blocking of the arm in the selected position, measuring these displacements through nonius coinciding in position with the precision rules of column and arm and located in the central area of the crosshead.
