Description

Technical Field

[0001] The utility model relates to the field of automated machinery, in particular to a multifunctional sensor connection device for a multi-modal non-destructive testing system. Background Art

[0002] Industrial CT, the full name of which is industrial computer tomography, is an advanced non-destructive testing technology. Based on the attenuation and absorption characteristics of radiation in the object being tested, industrial CT uses the attenuation law and distribution of X-rays or gamma rays emitted by radionuclides or other radiation sources in the object being tested, and obtains detailed information inside the object through the detector array. Finally, using computer information processing and image reconstruction technology, the internal structure, composition, material and defect status of the object being tested can be clearly, accurately and intuitively displayed in the form of two-dimensional tomographic images or three-dimensional stereo images.

[0003] Industrial CT technology involves multiple disciplines such as nuclear physics, microelectronics, optoelectronics technology, instrumentation, precision machinery and control, computer image processing and pattern recognition. Industrial CT is widely used in the automotive, material, railway, aerospace, aviation, military industry, national defense and other industrial fields. It provides important technical means for the successful launch of space launch vehicles, spacecraft and space vehicles, the development of aircraft engines, the inspection and testing of large weapon systems, geological structure analysis, railway vehicle speed-up and heavy-load safety, oil reserves prediction, and mechanical product quality determination.

[0004] However, the existing industrial CT sensors are generally controlled by fixed tracks or mechanical grippers, so that their positions are limited during detection and cannot meet detection requirements. Therefore, a connection device that can adjust the sensor position is needed. Utility Model Content
