Abstract

The invention discloses a structural dynamic defective optical fiber microscopic monitoring device, and belongs to the field of optics. The device solves the problem that the existing measuring device cannot monitor the surface state of the measuring device in a structural dynamic state. The device comprises a computer, a CCD (Charge Coupled Device) camera, an optical microscope, a fixed block, an optical fiber image bundle, an adapter, a miniature microscope, a close nipple, a two-dimensional fine adjustment system and a fixture, wherein the two-dimensional fine adjustment system comprises a longitudinal adjustment mechanism and a transverse adjustment mechanism; the fixture comprises a U-shaped groove and a locking knob; the bottom of the U-shaped groove of the fixture is fixedly connected with the two-dimensional fine adjustment system; an objective lens of the miniature microscope is embedded into one end of the close nipple; the other end of the close nipple is fixedly connected with a threaded through hole of the longitudinal adjustment mechanism; an ocular lens of the miniature microscope is communicated with one end of the optical fiber image bundle by the adapter; the other end of the optical fiber image bundle is communicated with an objective lens of the optical microscope by the fixed block; the CCD camera is arranged on an ocular lens side of the optical microscope; and the CCD camera is connected with the computer and used for monitoring component abrasion and defects.

Description

technical field [0001] The invention relates to an optical fiber microscopic monitoring device for structural dynamic defects, which belongs to the field of optics. Background technique [0002] The manufacture of mechanical components is mainly realized through welding, machining, casting and other processes. Due to the complexity and diversity of the production process, microscopic defects such as trachoma, scratches, cracks, and pits often appear on the surface of the components during the manufacturing process. . During the service process of mechanical components, these defects generated on the surface, due to the stress of high and low temperature, fatigue, corrosion, etc., microscopic defects develop into large defects, thereby reducing the corrosion resistance, wear resistance, fatigue limit, etc. of the components. The use performance directly affects the service life of the parts themselves, limits the performance of the equipment, and also brings great hidden dan...
