<p>An apparatus for checking dimensions and other geometrical features of pieces like shafts (20) or bushings (120) comprises support and reference devices (21; 110) for the piece, and checking devices (40; 70; 100; 119). Modular elements (5), equal to one another, are secured to two longitudinal cylindrical bars (1, 2) arranged one over the other. Linear guide portions (7) of the modular elements lie transversally, parallel to one another, and both the support and reference devices (21; 110) and the checking devices (40; 70; 100; 119) are adjustably connected to the linear guide portions (7). The checking devices comprise integral structures with movable arms (45; 73; 129) that touch the piece to be checked, and gauging heads (50, 85, 101, 134) actuated by the movable arms.</p> |
