TECHNICAL FIELD

[0001] The present application relates to the technical field of bolt detection, in particular to a bolt vibration detection platform. BACKGROUND

[0002] There are many connection methods in mechanical assembly, such as cross-section tightness connection, cementation, bolt connection, welding and pin connection. As a basic mechanical structural element, bolts are mainly used in the field of transmission and connection. Because bolt connection has the advantages of reliable connection, simple structure, convenient disassembly and large connection force, it has become the most widely used connection method. Fastening bolt standard parts have joined the standardization system with the remarkable features of threads and have realized large-scale production and universal interchange. They are widely used in various machines on the basis of improving product quality and reducing production cost. Because there are many types of bolt fasteners, various sizes, different use environments and specific requirements, and they are affected by complex loads and unpredictable factors, these factors bring certain difficulty to design and use. For example, in many key parts of mechanical structure, once the bolt connection is damaged, it will cause immeasurable loss. Due to the limitation of the basic structure principle of threads, loosening is a main form of failure of bolt fasteners, but the degree of loosening is difficult to judge. Therefore, it is particularly important to develop a bolt vibration loosening detection platform.

[0003] At present, the existing technology in the field of bolt vibration loosening mainly includes detection methods and detection devices, and most of the practical applications have limitations, and the detection devices are not suitable for large-scale popularization and application due to cost or other reasons. Therefore, it is particularly important and urgent to develop a bolt vibration loosening detection platform that can be applied in multiple occasions; based on this, a bolt vibration detection platform is proposed to provide a solution to the above problems.
