Automatic ultrasonic flaw-detecting machine for tray type large shell section parts

Abstract

The invention relates to a pallet-type large-scale ultrasonic automatic flaw detection machine for cylindrical joints, which includes a pallet and a track traveling trolley. There is a circular guide rail, and the rail traveling trolley is placed on the guide rail of the pallet to cooperate with the guide rail. The inner and outer large rotating arms driven by the oil cylinder are respectively connected to the inner and outer sides of the rail traveling trolley by rotating pairs. The rotating arms are respectively connected by rotating pairs with tubular inner and outer detection arms driven by oil cylinders. The inner and outer detection arms are respectively provided with detection arms; the inner and outer detection arms are connected with telescopic rods by moving pairs. , The end of the telescopic rod is equipped with an ultrasonic probe. Its advantages are: the workpiece can be placed and positioned freely on the workbench; the workpiece does not need to be rotated to save energy; the adverse effect of the workpiece rotation fluctuation on the detection is eliminated, and the stability is high; rack for easy positioning.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic flaw detection equipment, in particular to a pallet-type large-scale ultrasonic automatic flaw detection machine for cylindrical joints. Background technique [0002] Ultrasonic flaw detection can check the internal defects of the workpiece without destroying it. It is a key technology for quality assurance in the manufacture of major national projects and various important civilian products. The main components of large-scale power generation equipment, nuclear power plant equipment, various pipelines, bridge components, large-scale workpieces in marine, aviation and other fields require ultrasonic flaw detection to ensure the safe operation of the entire life of the equipment. [0003] Ultrasonic automatic flaw detection has been applied in developed countries such as Germany, the United States, and Japan, but its key technical information has been blocked. In China, ultrasonic automatic fla...

AI Technical Summary

Problems solved by technology

Judgment and identification are mainly based on national standards and specifications, personal technology and experience, and the detection results and personal standards are difficult to be consistent

The labor intensity of manual flaw detection workers is high, the time required for flaw detection of each workpiece is long, and the production cycle is greatly extended. It has even become a bottleneck restricting the entire production process chain of some enterprises, seriously affecting production progress and production efficiency; There are fewer operators, workers often work overtime, resulting in fatigue operation, and the detection process is prone to misjudgment, which affects the reliability and accuracy of workpiece flaw detection to a certain extent
