The invention discloses a multifunctional full-view three-dimensional adjustable microscopic visual device which comprises a full-view three-dimensional adjustable system and a microscopic visual system, wherein the full-view three-dimensional adjustable system comprises a base supporting platform, an X-axis rack shaft, a Y-axis rack shaft, an X-axis gear knob, a Y-axis gear knob, an X-axis sliding plate, a Y-axis sliding plate, a fixed disc base, a rotary bracket, a locking bolt, a Z-axis vertical rod, a Z-axis rack shaft, a Z-axis gear knob, a frame and a locking bolt; the microscopic visual system comprises an FIT CCD (Frame Interline Transfer Charge Coupled Device) camera, a coaxial lighting source, an optical microscope, a fixed bolt, a light source line and a signal line, and a computer acquiring and analyzing system. The multifunctional full-view three-dimensional adjustable microscopic visual device has the main advantages of realizing full-view and three-dimensional accurate adjustability, being capable of dynamically observing, recording and analyzing microscopic mechanical behaviors of a material in a microscopic mechanical test in real time and full process, being simple in structure and convenient to operate, and providing an effective tool for researching the microscopic mechanical behaviors of multiple materials such as coal, rock and metal.

Description

technical field [0001] The invention relates to the field of research on the mesoscopic mechanical behavior of materials, in particular to a multi-purpose mesoscopic visual device with full viewing angle and three-dimensional adjustment. Background technique [0002] With the continuous deepening of research work in various engineering fields, the exploration of the mechanical behavior of the research object has entered the mesoscopic stage. For example, coal and surrounding rock materials in the field of mining engineering are no longer satisfied with the study of their macroscopic dynamic phenomena and mechanical behavior. The mechanism and influencing factors of micro-void nucleation, growth and convergence, ductility, and macroscopic cracks and fracture damage are currently research hotspots. Another example is the research on the mechanical properties of materials such as rocks, concrete, and steel bars in the field of civil engineering, and the research on the load-be...

Problems solved by technology

At present, some scholars have developed related devices and equipment. Cao Shugang et al. invented a three-dimensional mobile microscopic observation device (application number: CN200820099769.3) using a hierarchical microscopic bracket arrangement mode. Its disadvantage is that the device is relatively complicated and bulky, and It is impossible to ensure that the observation line of sight and the crack development of the specimen are in a vertical perspective; Zhou Cuiying and others invented a three-axis adjustable microscopic observation system for rock-soil softening mesomechanics test (application number: CN200910036622.9). Realize the vertical viewing angle observation of the crack development of different test pieces, and the size that cannot be adjusted accurately in three dimensions

In summary, most of the visual devices are used for a certain type of test, and there are deficiencies such as unreasonable overall structure design, simple structure but few observation functions, and many functions but complex and bulky devices.
