[0003] In the prior art: the testing personnel will measure the horizontal deviation angle of the sound beam axis of the monoclinic probe for ultrasonic testing on the standard test block, but since there is no tool for measuring the angle, they are all measured with a protractor. Difficulty, the measurement value is not very accurate, and it is easy to cause misjudgment

The invention provides a gauge for a horizontal deviation angle of the axis of acoustic beams of a monoclinic probe and a detection method of the gauge, and relates to non-destructive testing. The gauge can fast detect whether the horizontal deviation angle of the axis of the acoustic beams of the monoclinic probe is qualified or not. According to the technical scheme, the gauge for the horizontal deviation angle of the axis of the acoustic beams of the monoclinic probe comprises an alignment plate and a cull which are connected together. An alignment face is arranged on the alignment plate. The cull is arranged in the mode that a 90-degree angle is formed between a flat plate and the alignment face. At least one measurement edge is arranged on the cull. An included angle alpha is formed between a vertical line of the alignment face and the measurement edge. The gauge has the advantages that as the size relation between the horizontal deviation angle of the axis of the acoustic beams transmitted by the probe can be fast detected, whether the probe is qualified or not is judged fast, the whole process is visual and simple, judgment is clear, and the detection speed of quality control is greatly increased.
Description
technical field [0001] The invention relates to non-destructive flaw detection, in particular to a detection tool for detecting the horizontal deviation angle of the sound beam axis of a monoclinic probe and a detection method thereof. Background technique [0002] Non-destructive testing is a method of transmitting ultrasonic beams through the probe and detecting internal defects of the test block through the reflection of the beams. Ideally, when the sound beam emitted by a single-slope probe (referred to as the probe) is flat, the sound beam emitted by the probe should be perpendicular to the emitting end face of the probe, that is, the horizontal deviation angle of the probe sound beam axis is 0. However, due to manufacturing reasons, the sound beam emitted by the probe generally cannot reach this ideal state, and the sound beam of the probe will deviate from the horizontal plane. Generally, the degree of deviation is measured by the horizontal deviation angle of the sou...
