Apparatus for the automatic inspection of the periphery of an article having an axis of symmetry

Apparatus for the automatic inspection of the periphery of an article having an axis of symmetry

The apparatus for automatically inspecting machined articles must allow inspection of all the articles of a batch and comprises a transparent plate (5) mounted on a rotating table (1). The article to be tested is placed in a groove in the plate (5), within a light beam (14) emitted by a source (15)....

description The apparatus for automatically inspecting machined articles must allow inspection of all the articles of a batch and comprises a transparent plate (5) mounted on a rotating table (1). The article to be tested is placed in a groove in the plate (5), within a light beam (14) emitted by a source (15). A line (34) of detectors scans an image of the article. The result of this scanning is transmitted to a computational device (CP) which defines the positions of the edges of the shadow of the article. By slowly rotating the table (1), the image of the article is sequentially scanned, and the computational device (CP) can indicate the length, width or axial curvature of the article.
