Apparatus with a supporting frame and process for manufacturing such a frame
First Claim
1. A gauge for checking linear dimensions of pieces with rotational symmetry, comprising positioning means for positioning the piece to be checked;
- gauging heads for checking linear dimensions of the piece support means for carrying out the positioning means and the gauging heads, the support means comprising a support base that defines two longitudinal parallel guides and intermediate support means with at least two transversal members longitudinally adjustable with respect to the support base; and
fastening means with at least two pairs of rapid fastening devices, for clamping the transversal members to the support base, wherein said support base comprises two pairs of longitudinal parallel bars and two transversal bars welded to the longitudinal bars for locally connecting them to one another, the longitudinal bars and the transversal bars having substantially rectangular cross-sections, each guide being defined by the associated bars of one of the two pairs and by the through space between these two bars, each rapid fastening device comprising a through element passing through the through space of an associated guide, a first limit stop element associated to an end of the through element and adapted for cooperating with the two bars of the associated pair of bars and a second limit stop element coupled in a movable way to the other end of the through element for cooperating with an end of an associated transversal member, in a position opposed to the first limit stop element with respect to the bars, for locking the end of the transversal member to the support base.

Abstract
A frame for supporting operative means includes two first, parallel metal beams arranged side by side and having the ends coupled to two second, parallel metal beams arranged perpendicularly to the first beams. In order to provide a rigid frame structure easy to manufacture depending on the features of the relevant apparatus and permitting quick coupling of the operative means in desired positions, the first beams are arranged to define a through slot for the passage of coupling elements coupling the operative means to the frame and for providing a guide for positioning the operative means in desired positions with respect to the frame. The second beams are welded at relevant ends of the first beams. The invention can also be applied for manufacturing frames including two pairs of parallel bars defining two guides, in particular frames of gauges for checking linear dimensions of parts.
