A guide device for a metal surface defect detection instrument

Abstract

The invention relates to the field of metal surface detection, in particular to a guide device for a metal surface defect detection instrument, comprising a placing plate, a fixing mechanism, a sliding mechanism, a limit mechanism, a detection mechanism, a cleaning mechanism and a collision mechanism; The placement plate and the metal surface are installed, fixed and adjusted, and at the same time, the sliding mechanism and the placement plate are slid, so as to facilitate the level detection of the metal surface, and play the role of guiding and positioning. When the sliding mechanism slides, the wear caused by the collision is reduced, and at the same time, under the action of the limit mechanism, the sliding mechanism cannot easily slide on the inside of the placing plate, which plays the role of braking protection. The mechanism follows the sliding mechanism to detect the metal surface in a certain direction, and at the same time cleans the dust and sundries on the metal surface under the action of the cleaning mechanism, so that the detection accuracy is higher.

Description

technical field [0001] The invention relates to the field of metal surface detection, in particular to a guide device for a metal surface defect detection instrument. Background technique [0002] Metal is a substance that has the properties of luster, that is, strong reflection of visible light, ductility, easy electrical conductivity, and thermal conductivity. Most of the metal elements on the earth exist in nature in a compound state, because most metals have relatively active chemical properties, and only a few metals such as gold and silver exist in a free state. Metals exist widely in nature. It is extremely common in life, and is a very important and most widely used type of material in modern industry. The refining and use of metals are everywhere. [0003] However, when using metal, it is also necessary to detect the surface defect of the metal, so as to make the metal processed products better. During the detection, the traditional method is to scan the metal surf...

[0003] However, when using metal, it is also necessary to detect the surface defect of the metal, so as to make the product after metal processing better. During the detection, the traditional method is to scan the metal surface with the probe of the detector, so as to obtain it on the computer. The information on the metal surface is used to judge whether the metal surface is good or bad. In this way, during operation, the hand-held probe will shake, so that the distance between the detection probe and the metal surface often changes, which affects the detection value. It is inconvenient to control the direction of detection, which reduces the efficiency of detection
