Portable metal surface defect laser scanning detection device

Abstract

The invention relates to the field of metal surface defect detection devices, in particular to a portable metal surface defect laser scanning detection device which comprises a fixing seat, a feedingstructure, a clamping structure, a fixing structure, a moving structure, a mounting structure and an ash removal structure. Through arranging the mobile structure, reciprocating comprehensive detection work can be carried out on the surface of the steel pipe, detection is more convenient and accurate, the moving speed is more uniform, and the requirement of improving the detection precision can bemet. Cooperating with the arrangement of the mounting structure, the scanning assembly can be conveniently clamped and disassembled. The device is convenient to install and replace. The ash removal structure can be synchronously driven to work while the moving structure works. Through work of the ash removal structure, dust outside a steel pipe can be removed while the steel pipe is detected, andtherefore the situation that the detection result of the steel pipe is affected by the dust on the surface of the steel pipe can be avoided.

Description

technical field [0001] The invention relates to the field of metal surface defect detection devices, in particular to a portable metal surface defect laser scanning 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. A steel pipe is a steel material with a hollow section whose length is much greater than its diameter or circumference. According to the cross-sectional shape, it can be divided into circular, square, rectangular and special-shaped steel pipes; according to th...

Problems solved by technology

[0003] Generally, in order to understand the production quality of the steel pipe, the surface defects of the steel pipe will be randomly checked. When the steel pipe is placed for a long time, a large amount of dust will accumulate on the surface of the steel pipe. Affect the surface detection effect of the steel pipe, resulting in inaccurate detection, and generally hold the scanning head by hand, because the manual movement speed is unstable and the uniformity is not easy to control, it will also affect the detection effect of the steel pipe
