Automatic ultrasonic C scanning detection system for annular forging

Abstract

The invention discloses an automatic ultrasonic C scanning detection system for an annular forging. The detection system comprises a mechanical scanning control unit, an automatic control mechanical scanning device, a rotary work platform, a water supply and drainage device, a water spray coupling device, an ultrasonic detection probe, an ultrasonic flaw detector and a communication unit thereof, data acquisition equipment and a C scanning nondestructive measurement unit, wherein the mechanical scanning control unit provides synchronous signals for the C scanning nondestructive measurement unit and controls the motions of the mechanical scanning device and the rotary work platform so as to drive the detection probe mounted in the water spray coupling device to scan; the water supply and drainage device is arranged on the edge of the rotary work platform so as to supply and drain water in real time; the ultrasonic flaw detector transmits and receives pulses through the detection probe and conveys detected echo information to the C scanning nondestructive measurement unit through the data acquisition equipment to perform imaging analysis. By adopting the system disclosed by the invention, the problems in ultrasonic detection of the annular forging with a complicated structure can be solved so that the imaging is accurate and visual.

Description

[0001] technical field [0002] The invention belongs to the field of ultrasonic non-destructive testing, in particular to an automatic ultrasonic C-scan testing system for ring forgings. Background technique [0003] Ultrasonic non-destructive testing technology is to scan the measured object according to a certain path through the ultrasonic detection probe on the premise of not damaging the parts or raw materials, so as to obtain the echo information inside the measured object, and then determine the defect and its size, etc. parameter. The advantages of ultrasonic testing are fast speed, low cost, high detection sensitivity, harmless to the human body, and can realize the positioning and quantification of internal defects of the workpiece. [0004] Traditional ultrasonic testing adopts manual operation, recording, and labeling. The disadvantages of this method are that there are blind spots in the detection, the bottom wave cannot be displayed locally due to the detecti...
