TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial imaging, in particular to an industrial CT / DR detection device. BACKGROUND

[0002] A large number of mechanical parts are used in modern industry, and the mechanical parts involve relatively closed pipelines, container structures, etc. Corresponding mechanical parts are mostly applied in high-temperature and high-pressure corrosive environments, and the corresponding workpieces need to be detected before leaving the factory.

[0003] When detecting, it is difficult to visually detect the inside of the workpiece, so in actual situations, an industrial CT / DR device is used to detect the workpiece. During detection, the workpiece needs to be handled, inspected, placed, returned, etc. Due to the limitation of the shape and structure of the workpiece, the position and orientation of the workpiece need to be adjusted in time; at the same time, the positions of the ray source and the detector also need to be adjusted in time; in the conventional industrial CT / DR device, the ray source and the detector are generally in a fixed state, and the workpiece on the workpiece carrying table changes the clamping position and direction by disassembly and assembly. When adjusting the position and direction of the workpiece, it is relatively troublesome to adjust, which further reduces the detection efficiency. At the same time, when detecting a workpiece with large mass and volume, the disassembly and assembly of the workpiece on the workpiece carrying table is not convenient, which further affects the detection efficiency of the workpiece.
