Mold surface self-adapting scanning and testing apparatus suitable for revolution body on-line ultrasonic flaw detection

Abstract

The invention provides a profile self-adaptive scanning device applicable for online ultrasonic flaw detection of a revolving body, comprising a clamping mechanism used for clamping and installing an ultrasonic probe, a base used for arranging the scanning device on a machine tool carrier and a distance self-adjusting mechanism used for attaching the working end surface of the probe clamping mechanism to the profile of the revolving body; the clamping mechanism comprises a clamping sleeve used for installing the ultrasonic probe and at least one angle adjusting ring, thus leading the end surface of the clamping sleeve to rotate corresponding to two mutually vertical axis lines; the clamping mechanism is arranged on the motion output terminal of the distance self-adjusting mechanism which is movably arranged on the base. The profile self-adaptive scanning device can realize processing the revolving body workpiece and executing the ultrasonic flaw detection at the same time, simplifies and shortens the production procedures of the revolving body workpiece, improves the production efficiency, reduces the production cost, and greatly improves the accuracy of the flaw detection at the same time. The profile self-adaptive scanning device also has the advantages of real-time adaptability of the change of the profile, high agility, convenient carrying, andconvenient disassembly and assembly, etc.

Description

technical field [0001] The invention relates to the technical field of non-destructive flaw detection, in particular to a profile adaptive scanning device suitable for on-line ultrasonic flaw detection of a rotating body. Background technique [0002] Ultrasonic testing technology is an important method and means in the field of non-destructive testing technology. It has been widely used because of its strong penetrating ability, high detection sensitivity, harmless to the human body, flexible use, and timely detection results. Applied to quality monitoring and security assurance in various industries. For important parts of large-scale rotating bodies (usually measured in tons) such as power generation equipment and pressure vessels, ultrasonic methods are usually used for non-destructive testing to detect structural defects generated during the manufacturing or use of such workpieces, so as to timely Find faults, analyze the causes and laws of defects and faults, improve ...

AI Technical Summary

Problems solved by technology

There are problems with this flaw detection method. First, the operator is highly subjective, and it is easy to miss inspection. When the operation is improper, it will cause the center of the probe to be inconsistent with the normal direction of the workpiece detection area, so that the ultrasonic waves emitted by the probe cannot enter vertically. Inside the workpiece, the defects inside the workpiece are detected, that is, the accuracy of manual flaw detection is not high, and it varies greatly due to different operators

Second, this detection method also leads to long production process of the whole workpiece, low production efficiency and high production cost

Until the completion of the present invention, the inventor did not see literature reports on the implementation of ultrasonic flaw detection while processing the surface of the rotating body
