Problems solved by technology

Most of the current radiographic flaw detection is aimed at the flaw detection of rotating bodies. Due to the complex geometric structure characteristics of non-rotating shafts, it is difficult to achieve continuous and effective flaw detection for non-rotating shafts such as crankshafts, and the radiation generated by radiographic flaw detection will affect the operation. It will cause great harm to personnel, and it is necessary to do a good job in radiation protection when performing radiographic inspection.

Abstract

The invention discloses a non-rotating shaft shaft crack detection device and method based on ray detection. The crack detection device includes a cross-shaped slide rail base, a two-way ball screw, a driving motor, a first support frame group, a second support frame group, a lifting mechanism, a one-way ball screw, a ball screw slide table, and a three-claw card. It is composed of disc, annular ray mounting frame, shutter and limit switch. By controlling the ball screw in three different directions and the mutual cooperation of the ball screw slide table, the opening and closing of the annular ray mounting frame and the movement of the shutter are completed. A crack detection. The device of the invention provides a shaft crack ray detection device aimed at irregular shafts with safety protection, simple operation and reliable performance.

Description

technical field [0001] The present invention designs the technical field of crack detection, more specifically, it is a non-rotating shaft shaft crack detection device based on radiation detection. Background technique [0002] Non-destructive testing is widely used in industrial production, and radiographic testing is a very important means of testing. Radiographic inspection is to detect defects by using the principle that rays penetrate substances and attenuate in substances. Radiographic inspection is not only suitable for metal flaw detection, but also for non-metal flaw detection. [0003] Radiographic flaw detection can check the internal defects of metal products and non-metallic products, such as air holes, pinholes, inclusions, looseness, cracks. Radiographic flaw detection can more intuitively display the size and shape of internal defects of the workpiece. It is used in special equipment, aerospace, ships, It has been widely used in bridge structures, and ray fl...
