Abstract

The invention discloses an automatic scanning device for ultrasonic wave detection. A first magnetic wheel and a second magnetic wheel are arranged on the scanning device, so that the scanning device can be tightly coupled with a metal wall, and inverted or vertical scanning can be met; a first adjusting screw rod and a second adjusting screw rod are arranged on the scanning device, so that the scanning device can be flexibly adjusted and thus is applicable to scanning on different curved surfaces and spherical metal walls; a sliding rear rod component is arranged, the tail part of the scanning device is not blocked and cannot steer because of tight coupling of the magnetic wheels and the metal wall in the steering process; a probe clamp arranged on a scanning arm and a water spraying device arranged on the scanning device are beneficial to detection on coupling of probes, and the scanning is enabled to be stable and reliable. The automatic scanning device is reasonable in structural arrangement, convenient to operate, stable and reliable in scanning, and applicable to scanning on different curved surfaces or spherical metal walls.

Description

technical field

[0001] The invention relates to the technical field of ultrasonic detection, in particular to an automatic scanning device for ultrasonic detection. Background technique

[0002] With the gradual popularization and application of new ultrasonic detection methods, especially the promotion and application of TOFD detection technology, it will greatly promote the improvement of detection efficiency.

[0003] In the traditional A-scan ultrasonic inspection, most of the inspectors manually operate the probe to inspect the workpiece. The limitation of the inspection method determines that the efficiency of this inspection method will be very low. An inspector performs the inspection in full accordance with the high standard requirements. One day The workload is only about 15 meters, and the detection efficiency is very low. In the past two years, the TOFD detection technology has been gradually promoted in China, and their scanning methods are very different from ...
