Device for manipulating a product and for processing radioscopy images of the product to obtain tomographic sections and uses

Abstract

The invention concerns a device produced in the form of an assembly which can be integrated in any installation (13) for radioscopy of the product and comprising means for driving the product (5) in rotation about an axis (5a) perpendicular to the tomographic section plane to be obtained, a unit controlling (15, 16) the means (14) driving the product (5) in rotation, to drive the product (5) in rotation about the axis (5a) and an image acquisition and processing unit (16) including means for automatically acquiring and storing radioscopy images of the product (5) while the product (5) is rotating, in digital form, and calculating means for processing the digital images and constructing tomographic sections using a calculating algorithm. The device enables fault controls or geometrical and dimensional controls in mechanical parts for the automotive industry such as cylinder heads.

Description

technical field [0001] The invention relates to a device and a method for manipulating products, in particular machine parts, and for processing images of products obtained in radiographic inspection equipment in order to obtain radiographic tomographic images of the products. Background technique [0002] In some mechanical industries, especially in the automotive industry, new parts and new casting methods are constantly being developed, and it is necessary to provide non-destructive inspection devices in order to evaluate parts produced by new designs or produced by new methods. Components. Specifically, the material of the part needs to be checked qualitatively and quantitatively in order to determine whether it has any defects, and the size and geometry of the part need to be checked in areas of the part that cannot be accessed by conventional means, such as cavities or grooves inside the part. examine. [0003] Specifically, in the case of aluminum alloy castings or ...

AI Technical Summary

Problems solved by technology

[0020] This equipment has limited capabilities, in particular the inability to check the solidity of the material making up the part in a section through the part

[0021] Likewise, conventional radiographic inspection methods cannot perform dimensional and geometric inspections inside parts

[0022] More generally, on production lines for the production of industrial products such as parts or other products, there are usually no practical devices capable of performing cross-sectional examination of the products
