A wheel hub detection system and detection method based on X-ray

Abstract

The invention provides a wheel hub detection system based on X-rays. The wheel hub detection system comprises an upper computer, a lower computer, a ray source, an image intensifier, a high-pressure generator and a CCD image sensor, wherein a semi-automatic defect detection system is arranged in the upper computer, and a PLC machine control system and a high-pressure control system are arranged in the lower computer. The invention also provides a detection method applied to the wheel hub detection system based on the X-rays. The method comprises the following steps: initial setting; establishing a wheel hub model station database; identifying wheel hub models; using the system to regulate a wheel hub camera site and the strength of the ray source; judging the qualification of wheel hubs by a user; shunting the wheel hubs. According to the wheel hub model station database established in advance, in the working process of the system, the system automatically regulates the wheel hub camera site and the strength of the ray source to realize the semi-automatic detection for wheel hub defects. The wheel hub detection system has the advantages of intelligentization, high regulating efficiency, good effect and the like.

Description

technical field [0001] The invention relates to an X-ray defect detection technology, in particular to an X-ray-based wheel hub detection system and its detection method. A system and method for realizing automatic selection of image shooting stations by wheel type recognition. Background technique [0002] At present, the X-ray image detection system is often used for defect detection in the production of wheel hub castings, that is, through the X-ray source and ray intensifier, the radiographic image of the hub is obtained for defect detection and analysis. Limited by the shooting area of ​​the image intensifier, it is usually necessary to take 3 to 9 images ranging from the front and side of a wheel hub to detect all parts of the wheel hub. In the existing hub defect detection system, both the ray intensifier and the hub need to be moved to appropriate positions in order to obtain radiographic images of various parts of the hub. In the existing defect detection system, ...

Problems solved by technology

In this way, when the operator detects defects on the assembly line, each hub needs to manually adjust the position of the intensifier and the hub according to the position to be inspected, and change the intensity of the ray source at any time according to the needs, that is, the current and voltage parameters. The operation is cumbersome; secondly, the stability is poor, and manual adjustment It is difficult to ensure that all key parts of the wheel hub can be completely inspected, and some parts may be missed due to human negligence; more importantly, this manual adjustment method cannot carry out subsequent automatic inspections, because the automatic recognition and detection algorithm of the image depends on all The set position value and the automatically provided ray source parameters
