A testing device for non-destructive testing of internal defects in iron castings

Abstract

The invention relates to the technical field of detection of flaws in iron castings, and discloses a detection device for the nondestructive detection of flaws in iron castings, which comprises a detection base, a stand which is connected to a bearing bracket is mounted on the detection base, a detection trough is mounted under a bearing plate in which an X-ray tube is mounted, an X-ray imaging mechanism is mounted under the detection trough, the output end of an amplifier of the X-ray imaging mechanism is connected to the input end of a digital-to-analog converter, the output end of the digital-to-analog converter is connected to the input end of an image processing computer, the second output port of the image processing computer is connected to the input end of an analog-to-digital converter, the output end of the digital-to-analog converter is connected to the input end of an execution controller of a handling mechanism, and a first storage trough and a second storage trough are respectively mounted on the left side and right side of the handling mechanism. The invention solves the problem that conventional detection devices for detecting flaws in iron castings cannot carry outefficient nondestructive detection.

Description

technical field [0001] The invention relates to the technical field of detection of internal defects of iron castings, in particular to a detection device used for non-destructive detection of internal defects of iron castings. Background technique [0002] Castings are metal forming objects obtained by various casting methods, that is, the smelted liquid metal is injected into the pre-prepared casting mold by pouring, injection, suction or other casting methods, and after cooling, after grinding and other subsequent processing methods. , The obtained objects have a certain shape, size and performance. The quality of the casting has a great influence on the performance of the mechanical product. In the casting production, the quality of the casting should be controlled and inspected. For the internal defects of the casting, the commonly used non-destructive testing method It is radiography and ultrasonic testing. [0003] Items cast with molten iron are collectively referre...
