[0003] A fatigue testing machine in related technology includes a frame, a placement platform on the frame, a hydraulic cylinder above the frame, and an actuating head on the output shaft of the hydraulic cylinder, the actuating head facing the placement platform. When performing fatigue testing on materials, simply place the material to be tested on the placement platform, then activate the hydraulic cylinder. The hydraulic cylinder drives the actuating head to perform repeated dynamic or long-term static fatigue tests on the material.

[0004] The inventors of this application discovered at least the following problems during the implementation of the aforementioned fatigue testing machine:

[0005] Fatigue testing machines need to test different specimens, such as springs, rolling balls, and steel bars, so different placement platforms and actuating heads are required. In related technologies, the placement platforms of fatigue testing machines are fixed with screws, which is cumbersome to install and remove, and is not conducive to the disassembly and replacement of the placement platform.

[0026] Please refer to the following for details. Figure 1-3 A replaceable structure for a testing machine includes a workbench 1 and a placement platform 2. The placement platform 2 is detachably connected to the workbench 1. A first connector 3 is provided on the workbench, and a second connector 4 is provided on the placement platform 2. The second connector 4 cooperates with the first connector 3. The outer periphery of the first connector 3 is provided with two opposing first side ears 5 and two opposing first inserts 6. The outer periphery of the second connector 4 is provided with two opposing second side ears 7 and two opposing second inserts 8. A first insertion groove 12 is provided on the first side ears 5, and the second inserts 8 can be inserted into the first insertion groove 12. A second insertion groove 13 is provided on the second side ears 7, and the first inserts 6 can be inserted into the second insertion groove 13.

[0027] Based on the above technical means: when it is necessary to disassemble and replace the placement platform 2, simply rotate the placement platform 2 to unscrew the first insert 6 from the second insert slot and the second insert 8 from the first insert slot, and then the placement platform 2 can be removed, and other placement platforms 2 can be rotated; when it is necessary to install the placement platform 2, simply place the placement platform 2 on the first connector 3, align the first connector 3 and the second connector 4, and rotate the placement platform 2 to screw the first insert 6 into the second insert slot and the second insert 8 into the first insert slot to complete the connection of the placement platform 2. After rotating to the correct position, the first side ear 5 and the second side ear 7 abut against each other, the second insert 8 is fully inserted into the first insert slot 12, and the first insert 6 is fully inserted into the second insert slot 13. The placement platform 2 is installed on the workbench by rotation, which facilitates the disassembly and replacement of the placement platform 2 and improves work efficiency.

[0028] Furthermore, a hemisphere 9 is provided at the middle position of the top surface of the first connector 3, and a hemisphere cavity 10 is provided at the middle position of the bottom surface of the second connector 4. The hemisphere cavity 10 fits into the hemisphere 9. The hemisphere 9 is embedded in the first connector 3. The hemisphere 9 and the hemisphere cavity 10 work together to achieve alignment and reduce the friction between the first connector 3 and the second connector 4, making it easier to rotate the placement platform 2.

[0029] Furthermore, the first insertion groove extends from one end face of the first side ear 5 to the other end face of the first side ear 5, and the second insertion groove extends from one end face of the second side ear 7 to the other end face of the second side ear 7.

[0030] Furthermore, the first insert 6 has a bevel 11 at one end, and the second insert 8 has a bevel 11 at one end. The design of the bevel 11 makes it easier for the insert to enter the insertion slot.

[0031] Furthermore, the upper surface of the first insert 6 is flush with the lower surface of the first insert 6, and the upper surface of the second insert 8 is flush with the lower surface of the second insert 8.

[0032] Furthermore, the length of the first insert 6 is equal to or less than the length of the second insert slot, and the length of the second insert 8 is equal to or less than the length of the first insert slot.

[0033] Furthermore, the placement platform 2 includes a flat placement platform, a recessed placement platform, and a clamp placement platform.
