Description

Technical Field

[0001] The present invention relates to the field of metal detection, and in particular to a precision detection device for metal product processing and a detection method thereof. Background Art

[0002] Metal pipes are one of the main equipment for transporting liquids and gases. The working environment of pipes is complex and harsh. The inside and outside of the pipes may be widely exposed to smoke, fire, gas and other media. The metal pipes themselves have to withstand high temperature and high pressure. Due to oxidation and corrosion, the pipes often have abnormalities such as dents or bulges, which can easily cause pipe bursts and leakage accidents, seriously affecting production.

[0003] Therefore, during pipeline production, it is necessary to use detection devices to detect the pipelines in the factory to eliminate safety hazards at an early stage. Existing pipeline detection equipment usually uses workers to hold detection instruments for detection. However, when encountering some gas transportation pipelines, the gas transportation pipelines are often very long, and in order to ensure the sealing of the gas, the gas transportation pipelines are often made in one piece and are often very long. Therefore, when it is necessary to detect metal pipelines, the traditional manual detection method has too much workload. Based on this, we propose a precision detection device for metal product processing and a detection method thereof. Summary of the invention

[0010] As a further improvement of the above scheme, the staff rotates the handle, which drives the connecting screw to rotate, and the connecting screw drives the mounting plate to move. The ultrasonic detection head connected to the mounting plate is simultaneously adjusted in position to adjust the distance between the ultrasonic detection head and the metal pipe, so that the ultrasonic detection head can perform ultrasonic detection on metal pipes of different sizes and perform ultrasonic detection on the surface of the metal pipe.

[0011] As a further improvement of the above solution, three groups of positioning and scanning mechanisms are provided, and the three groups of positioning and scanning mechanisms surround the metal pipe.
