Multi-degree-of-freedom, multi-angle rotating device

Abstract

The invention discloses a multi-degree-of-freedom and multi-angle rotating device which comprises a horizontal rotary working table and a vertical rotary working table, wherein the vertical rotary working table comprises a power source, a gear box and a transmission mechanism, the gear box is fixedly arranged on the horizontal rotary working table, the transmission mechanism is used for connecting the power source with the gear box, the gear box comprises at least one power output shaft which is horizontally arranged, the power output shafts are parallel in a vertical direction, and a piece carrying platform which is perpendicular to each power output shaft is fixedly arranged on the power output shaft. Workpieces can be rotated on a horizontal surface and a vertical surface by using the horizontal rotary working table and the vertical rotary working table of the multi-degree-of-freedom and multi-angle rotating device, so that parts can be scanned at different azimuth angles by a radiation source, comprehensive scanning detection data are acquired, and the detection accuracy is good. By adopting the rotating device, the scanning cost can be reduced, additionally, multiple workpieces can be scanned at a time, large-batch and assembly-line operation is facilitated, and the detection efficiency can be greatly improved.

Description

technical field

[0001] The invention relates to the field of industrial computerized tomography scanning equipment, in particular to a working table of the scanning equipment. Background technique

[0002] Industrial computerized tomography (ICT) is a non-contact advanced non-destructive testing method. It can display the internal structural relationship and defect status of the detected object in the form of tomographic images without damaging the material and structure of the workpiece. Therefore, it is a practical nondestructive testing technology. The scanning methods commonly used in industrial CT can be divided into three categories: translation-rotation (TR) scanning, rotation-only (RO) scanning and helical scanning. The above three scanning methods all need to realize the rotational movement of the workpiece relative to the ray source and the detector. When the detected workpiece rotates more than 180°, a tomographic image can be reconstructed. If the tomographic de...
