Automatic flaw detection device for steel pipe production

Abstract

The invention discloses an automatic flaw detection device for steel pipe production, and relates to the technical field of steel pipe production. The device comprises a base, the top surface of the base is concave; a servo motor and a rotating shaft are fixedly installed in the concave position of the top face of the base, containing frames are fixedly installed on the two sides of the top face of the base, the containing frames are located above the rotating shaft, a gear is fixedly installed on the rotating shaft, the rotating shaft is in transmission connection with a servo motor through the gear, and idler wheels are further fixedly installed on the rotating shaft. A detection mechanism is arranged to match a linear motor and the servo motor. A probe of the detection mechanism makes contact with a steel pipe. When the steel pipe matches the probe in the rotating process and is sunken, the probe can descend, and after the probe descends, it is judged that damage exists on the surface of the steel pipe. The detection precision can be regulated and controlled according to the radius of the free end of the probe. Compared with the traditional infrared detection, the detection is more accurate, and the maintenance and the cost are lower.

Description

technical field [0001] The invention relates to the technical field of steel pipes, in particular to an automatic flaw detection device for steel pipe production. Background technique [0002] During the production process of the steel pipes, especially the steel pipes that have not been cooled, collisions occur during the transportation process. Due to the low hardness of the steel pipes at high temperatures, the collision between the steel pipes will cause damage to the steel pipes. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an automatic flaw detection device for steel pipe production. After use, it can solve the problem in the prior art that the automatic flaw detection device for steel pipe production relies too much on the accuracy of the probe head and sensor. , the maintenance cost is high, and the situation of lunch is prone to occur during detection. [0004] In order to achieve the above purpose...
