Embodiment Construction
[0018] The tabletop material mechanics testing machine of the present invention can complete four kinds of tests of compression, tension, cantilever beam bending and simply supported beam bending, and its overall structure is as follows: figure 1 As shown, it includes a table frame 1, a transmission loading mechanism, a direction changing mechanism and an actuator. The table frame 1 is a support welded by square steel, the left side, the right side and the top face are covered with planks, and the table legs are equipped with rubber pads. The transmission loading mechanism is installed on the bottom of the table frame 1, and the direction changing mechanism and the executive mechanism are installed on the top of the table frame 1.
[0019] The transmission loading mechanism includes a motor 3, a coupling 4, a pinion shaft 5, a large gear shaft 6, a torque limiter 7, a reel 8 and a steel wire rope 2, and the reel 8, the pinion shaft 5 and the large gear shaft 6 pass through the...

A table-top material mechanics testing machine, comprising a table frame, a transmission loading mechanism, a direction-changing mechanism and an executive mechanism; the transmission loading mechanism is arranged at the lower part of the table between agencies and executive agencies. Set the test piece on the actuator, load the test piece through the transmission loading mechanism and the direction changing mechanism, and realize four material mechanics tests of tension, compression, cantilever beam bending and simply supported beam bending by changing the connection mode of the steel wire rope. The testing machine has a compact overall structure, takes up little space, and has various test functions; the parts in the actuator are easy to disassemble and install, which is convenient for the conversion and maintenance of various tests, and can output stable loads, and can realize tension, compression, cantilever beam bending and simple testing. Bending four kinds of material mechanics test of beam.
Description
technical field [0001] The invention relates to a device for mechanical testing of materials, belonging to the technical field of mechanical testing machines. Background technique [0002] Mechanics of materials is the basic subject of engineering. Mechanics of materials experiment is also an important means to study and analyze the physical and mechanical properties of materials. For the performance testing of metal materials, non-metal materials and mechanical parts, material mechanics testing machine is an indispensable testing equipment. . [0003] In recent years, the continuous development of new technology and new material science has higher and higher requirements for material mechanics testing machines. The research and development of various new material mechanics testing machines that meet different requirements have broad prospects. [0004] However, when the existing material testing machine is used, there are problems such as difficult disassembly and maintena...
