[0027] In this embodiment, the material to be tested is placed in the middle of the fixing frame 24 of the bottom fixing mechanism 2, and then the first hydraulic cylinders 23 on the four sides of the bottom fixing mechanism 2 push the clamping plate 22 to clamp and fix the lower half of the material from four directions. At this time, the pressure testing mechanism 5 can be lowered to perform compression strength and hardness tests on the material. When the material needs to be tested for torsional strength, the clamping and fixing mechanism 3 is used to clamp and fix the upper half of the material to be tested, and then the clamping and fixing mechanism 3 is rotated in conjunction with the torque testing mechanism 4. At the same time, the bottom fixing mechanism 2 stably fixes the lower half of the material, thereby performing a torsional strength test on the material, which is compatible with test materials of different volumes.

A motor 42 is fixedly installed on the left end of the frame 43, and a planetary reduction gear set 41 is driven and installed at the bottom of the motor 42. The planetary reduction gear set 41 is meshed with the tooth groove 45 on the outer surface of the turntable 44, and the clamping and fixing mechanism 3 is fixedly installed at the bottom of the turntable 44.
[0029] In this embodiment, when it is necessary to perform a torsional strength test on the material, the upper half of the material to be tested is clamped and fixed by the clamping and fixing mechanism 3, and the motor 42 drives the turntable 44 to rotate through the planetary reduction gear set 41.

[0032] The following is a detailed description of the working principle of this microcomputer-controlled electronic universal testing machine.
[0033] like Figure 1-5As shown, the material to be tested is placed in the middle of the fixing frame 24 of the bottom fixing mechanism 2, and then the first hydraulic cylinders 23 on the four sides of the bottom fixing mechanism 2 push the clamping plate 22 to clamp and fix the lower half of the material from four directions. At this time, the pressure testing mechanism 5 can be lowered to perform compression strength and hardness tests on the material. When it is necessary to perform a torsional strength test on the material, the clamping and fixing mechanism 3 is used to clamp and fix the upper half of the material to be tested, and then the clamping and fixing mechanism 3 is rotated in conjunction with the torque testing mechanism 4. At the same time, the bottom fixing mechanism 2 stably fixes the lower half of the material, thereby performing a torsional strength test on the material, which is compatible with test materials of different volumes. When it is necessary to perform a torsional strength test on the material, the clamping and fixing mechanism 3 is used to clamp and fix the upper half of the material to be tested, and the motor 42 drives the turntable 44 to rotate through the planetary reduction gear set 41. The planetary reduction gear set 41 can increase the torque of the motor 42. The rotation of the turntable 44 drives the clamping and fixing mechanism 3 to rotate, Part of the material is twisted, and the bottom fixing mechanism 2 stably fixes the lower half of the material, so as to test the torsional strength of the material. The substrate 55 is slidably limited and clamped on the pressure frame 52 through the limit pulleys 51 at both ends. The substrate 55 is pushed by the second hydraulic cylinder 53 to cooperate with the limit pulley 51, so that the substrate 55 can be lifted and lowered along the pressure frame 52. When the material needs to be tested for tensile strength, compression strength, and hardness, the substrate 55 is pushed down by the second hydraulic cylinder 53, so as to test the compression strength and hardness of the material fixed by the bottom fixing mechanism 2. When the tensile strength needs to be tested, the clamping and fixing mechanism 3 at the bottom of the substrate 55 clamps and fixes the upper half of the material to be tested, and cooperates with the bottom fixing mechanism 2 to fix the lower half of the material. The substrate 55 is driven up by the second hydraulic cylinder 53 to test the tensile strength of the material.
