Abstract

Belonging to the technical field of TOFD detection equipment, the invention specifically discloses a TOFD automatic scanning device. The device comprises a main beam with a hollow inner structure, a movable groove is disposed at the bottom of the main beam, a gearbox is mounted at a top central position of the main beam, the gearbox is communicated with the inner cavity of the main beam, and an active conical gear is longitudinally arranged at a central position of the gearbox's inner cavity, a motor is installed on the right side of the gearbox, the left side power output end of the motor isfixedly connected to the right side of the active conical gear through a transmission shaft, the bottom of the active conical gear is in engaged connection with a driven conical gear, rotation of themotor can realize adjustment of the distance between probes and rollers, and the probes and rollers can realize linkage, thus improving the detection efficiency. And through arrangement of arc-shapedbrackets and springs, the rollers can cling to pipe walls, thus preventing dangling phenomenon of the rollers, and improving the image definition.

Description

technical field [0001] The invention relates to the technical field of TOFD detection equipment, in particular to a TOFD automatic scanning device. Background technique [0002] TOFD, ultrasonic time-of-flight diffraction method. Technology for the detection, quantification and localization of material defects. The TOFD scanner relies on the diffraction energy obtained from the "end angle" and "end point" of the internal structure of the test piece to be inspected (mainly refers to the defect) to detect the defect, which is used for the detection, quantification and positioning of the defect. When the existing TOFD scanner performs detection, the distance between the roller and the probe time needs to be adjusted separately, and the distance between the rollers is not easy to adjust, and the scanning speed is slow, the image is not clear, and the detection efficiency is low. , we propose a TOFD automatic scanning device. Contents of the invention [0003] The purpose of...
