[0002] Beam-type mechanical parts are generally used as the main load-bearing parts of the overall structure and are widely used in mechanical equipment. The structural integrity of beam-type mechanical parts will directly affect the safe and reliable operation of the equipment. Mechanical equipment is becoming increasingly large-scale, high-speed, precise and intelligent, which also makes the working environment and stress conditions of mechanical parts increasingly complex. It is very easy to be damaged when the equipment is running, posing a huge hidden danger to the national economic production and human life.

[0003] At present, X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, etc. are commonly used for damage detection of mechanical parts. Damage identification and detection of beam-type mechanical parts based on sound signals has the characteristics of non-contact measurement, convenient collection and fast processing speed. This method is expected to be intelligent and universal, and can effectively identify the damage degree and damage location of beam-type mechanical parts. To carry out damage identification and detection of beam-type mechanical parts based on sound signals, a fixture for beam-type mechanical parts is needed. However, existing fixtures have some functional defects. For example, most of the existing fixtures are not universal, and the cross-sectional shape and size of the mechanical parts that can be clamped are single, which makes it inconvenient to replace mechanical parts and inconvenient to adjust the spatial position. When replacing mechanical parts of different models, different clamping blocks need to be replaced, resulting in most of the time wasted on the clamping of mechanical parts, low experimental efficiency, and inconvenient replacement when the fixture fails and needs maintenance, affecting the overall efficiency.
