Problems solved by technology

However, due to the skin effect of the eddy current, the penetrating eddy current flaw detection cannot distinguish the small defects on the inner wall of the steel pipe with high sensitivity. If there are strict requirements on the inner wall defects, the defects on the inner wall of the steel pipe must be re-detected, which seriously affects the detection efficiency.
The flaw detection of inner wall defects of stainless steel pipe is special, and only offline eddy current flaw detection can be carried out

Abstract

The invention relates to a feeding and discharging device for simultaneous eddy current flaw detection applied to inner and outer walls of a stainless steel short pipe. The feeding and discharging device comprises a feeding assembly, a conveying assembly, a detection matching assembly and a discharging assembly which are sequentially arranged in the advancing direction of the stainless steel shortpipe, wherein the detection matching assembly comprises two V-groove supports and a moving platform, wherein the two V-groove supports can vertically lift up and down, and the moving platform is arranged between the two V-groove supports and is capable of lifting up and down; and the tops of the V-groove supports are machined with a V-shaped groove capable of stably placing a stainless steel short pipe, and the top of the moving platform is machined with a guide inclined plane for receiving the conveying assembly and the discharging assembly. Compared with the prior art, the method can ensurethe matching consistency with the eddy current detection process, the unstable influence during detection is avoided, and finally the reliability of the detection result is ensured; and in the wholedetection process, successive feeding of the steel pipes can be achieved, the feeding interval time of the steel pipes can be regulated, time and labor are saved, and flexible and reliable effects areachieved.

Description

technical field [0001] The invention belongs to the technical field of loading and unloading devices, and relates to a loading and unloading device for simultaneous eddy current flaw detection on the inner and outer walls of short stainless steel pipes. Background technique [0002] Eddy current testing is one of the most commonly used non-destructive testing methods in modern industry. It has the advantages of fast detection speed and high detection sensitivity, and does not need to detect coupling media and has no pollution to the environment. It is widely used in defect detection. [0003] Stainless steel pipes are widely used in industries such as automobiles and household appliances, and the quality requirements for pipes are extremely strict. Usually, eddy current testing is used to control the defects on the inner and outer surfaces of stainless steel pipes. At present, in the eddy current inspection of stainless steel pipes, the through-type eddy current probe is ge...
