[0021] The following will describe in detail the embodiments of the present application in conjunction with the accompanying drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.
[0022] As Figures 1-4 shown, the single-arm tensile-torsion testing machine provided in this embodiment includes a tensile-compressive-torsion power box 1. An electronic rotation device is provided inside the tensile-compressive-torsion power box 1. A fixed seat 11 and a frame 2 are fixedly connected to the upper surface of the tensile-compressive-torsion power box 1. A torsion seat 3 is fixedly connected to the first output end of the electronic rotation device. The outer wall of the torsion seat 3 is rotatably connected to the inner wall of the fixed seat 11. A lead screw and a guide rail are provided inside the frame 2. One end of the lead screw is fixedly connected to the second output end of the electronic rotation device. A tensile-compressive moving arm 4 is threadedly connected to the lead screw. The tensile-compressive moving arm 4 is slidably connected to the guide rail. A force-measuring sensor 41 is fixedly installed on the tensile-compressive moving arm 4. A force-measuring connecting piece 42 is fixedly connected to the force-measuring sensor 41. The force-measuring connecting piece 42 is located at a position below the force-measuring sensor 41. Connecting rods 31 are fixedly connected to both the force-measuring connecting piece 42 and the torsion seat 3. By controlling the first output end of the electronic rotation device to drive the torsion seat 3 to rotate, the torsion seat 3 drives the connecting rod 31 fixed on the torsion seat 3 to rotate, and a torsion test is performed on the specimen. By controlling the second output end of the electronic rotation device to drive the lead screw to rotate, the lead screw drives the tensile-compressive moving arm 4 to move. The tensile-compressive moving arm 4 drives the force-measuring sensor 41 and the force-measuring connecting piece 42 to move. The force-measuring connecting piece 42 drives the connecting rod 31 fixed on the force-measuring connecting piece 42 to move, and a tensile-compressive test is performed on the specimen. At the same time, by controlling the first output end and the second output end of the electronic rotation device, a torsion and tensile-compressive test can be performed on the specimen simultaneously.
[0023] Secondly, as Figure 1 , Figure 2 and Figure 3As shown, a fixture 32 is fixedly connected to the other end of the connecting rod 31. Two sliding rods 33 are slidably connected in the other side direction of the fixture 32. A return spring 34 is provided between the sliding rod 33 and the fixture 32. One end of the return spring 34 is fixedly connected to the fixture 32, and the return spring 34 is fixedly connected to one end of the sliding rod 33.

Dust-proof curtains 6 are fixedly connected to both the upper and lower sides of the tension-compression moving arm 4. Both dust-proof curtains 6 are slidably connected to the inner walls of both sides of the frame 2. The other end of the upper dust-proof curtain 6 is connected to the upper cover plate 22, and the lower dust-proof curtain 6 is connected to the tension-compression torsion power box 1. The dust-proof curtain 6 is used for dust-proofing the tension-torsion testing machine.
[0027] As Figures 1-4As shown below, the principle of the single-arm tensile-torsion testing machine provided in this embodiment is as follows: When using this single-arm tensile-torsion testing machine, the first output end of the electronic rotation device is controlled to drive the torsion seat 3 to rotate. The torsion seat 3 drives the connecting rod 31 fixed on the torsion seat 3 to rotate, and a torsion test is performed on the specimen.

[0028] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but use the difference in functions of components as the criterion for distinction. As mentioned throughout the specification and claims, "comprising" is an open-ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve technical problems within a certain error range and basically achieve the technical effect.
[0029] It should be noted that the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent in such a commodity or system. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or system including the element.
