Metal limiting mechanism of ultrasonic metal surface defect detection device

Abstract

The invention relates to the field of metal surface defect detection devices, in particular to a metal limiting mechanism of an ultrasonic metal surface defect detection device. The mechanism comprises a base, a sliding structure, an abutting structure, a rotating structure, a fixing structure, an ejecting structure and an adjusting structure. A sliding structure is further installed at the top end of the base. The steel pipe can be conveniently placed. Steel pipes with different lengths can be clamped and fixed in cooperation with the abutting structure. Therefore, defect detection can be conveniently carried out on the steel pipe. The rotating structure is mounted in the sliding structure, the clamped and fixed steel pipe can be rotated in all directions, so detection personnel can carryout comprehensive detection conveniently, and detection effect can be improved. Through the arrangement of the fixing structure, the steel pipes can be clamped and fixed, the steel pipes with different internal diameters can be clamped and fixed, and therefore the applicability of the device can be greatly improved, and detection is facilitated.

Description

technical field [0001] The invention relates to the field of metal surface defect detection devices, in particular to a metal limit mechanism of an ultrasonic metal surface defect detection device. Background technique [0002] Metal is a material with luster (that is, strong reflection of visible light), high ductility, easy conduction of electricity, and heat conduction. Most of the metal elements on the earth exist in nature in a compound state. This is because the chemical properties of most metals are relatively active, and only a few metals such as gold and silver exist in a free state. Metals exist widely in nature and are widely used in daily life. They are very important and most widely used substances in modern industry. Steel pipes belong to the category of metals. Steel pipes are steel products with a hollow section whose length is much greater than the diameter or circumference. According to the cross-sectional shape, it can be divided into circular, square, ...

AI Technical Summary

Problems solved by technology

[0003] Generally, in the production and processing process of steel pipes, in order to ensure the production quality of steel pipes, it is necessary to use ultrasonic testing heads to detect defects on the surface of steel pipes. The surface of the steel pipe placed on the ground is inspected. The general inspection requires an all-round inspection of the steel pipe, and the steel pipe needs to be turned over during the inspection, which is very inconvenient to operate.
