Detection device for nondestructive detection of flaws 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 internal defect detection of iron castings, in particular to a detection device for non-destructive detection of internal defects of iron castings. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods , the obtained objects have a certain shape, size and performance. The quality of castings has a great influence on the performance of mechanical products. In casting production, the quality of castings must be controlled and inspected. For internal defects of castings, the commonly used non-destructive testing method It is radiographic inspection and ultrasonic inspection. [0003] Articles cast with molten iron are collectively called iron castings. Due to var...
