Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described as follows:

[0021] A multi-station torsional fatigue testing machine includes a lower frame 7, with anchor bolts 9 at the bottom of the lower frame 7, a control cabinet 8 inside the lower frame 7, a computer control system installed inside the control cabinet 8, a workbench 6 at the top of the lower frame 7, multiple fixed frames 3 evenly arranged on the top of the workbench 6, an openable protective cover 2 outside the fixed frame 3, and a handle 15 on the outside of the protective cover 2.

[0022] In this embodiment, the computer control system is a reapplication of existing technology in this utility model.

[0023] Multiple torsional fatigue testing devices are evenly arranged between the workbench 6 and the fixed frame 3. The torsional fatigue testing device includes a torque sensor 4 and a lower tooling plate 5. The torque sensor 4 is fixedly installed on the lower top side of the fixed frame 3. A power motor 13 is fixedly installed on the lower part of the workbench 6. The output end of the power motor 13 passes through the workbench 6 and extends to the top of the workbench 6. The output end of the power motor 13 is fixedly connected to the lower tooling plate 5, which cooperates with the torque sensor 4. A fine adjustment knob 14 is provided on the lower tooling plate 5. The torque sensor 4 and the power motor 13 are electrically connected to the computer control system.

[0024] In this embodiment, the number of torsional fatigue testing devices can be increased or decreased as needed. Preferably, two fixed frames 3 are provided on the workbench 6, and five torsional fatigue testing devices are provided on each fixed frame 3. The user can control the stop or start of one torsional fatigue testing device individually through the computer control system, or control multiple torsional fatigue testing devices to stop or start simultaneously.

[0025] A power switch 12 is installed on the left or right side of the control cabinet 8, and the power switch 12 is electrically connected to the computer control system.

[0026] The front side of the control cabinet 8 is equipped with a power indicator light 10 and an emergency stop button 11, which are electrically connected to the computer control system.

[0027] The protective cover 2 is equipped with a test alarm 1, which is electrically connected to the computer control system.

[0028] In use, this invention begins by opening the protective cover 2 via handle 15. The test material or component is then fixed between the torque sensor 4 and the lower fixture plate 5 using the fine-tuning knob 14. The power switch 12 is turned on, and the computer control system controls the motor 13 to rotate, causing the test material or component to rotate on the lower fixture plate 5. The torque sensor 4 generates torque and transmits the test data to the computer control system. Feedback from the torque sensor 4 is then used to determine whether the test material or component is subjected to the same or different torques, whether it is damaged, or whether the set test conditions have been met (i.e., the number of tests has been reached or the torque has decreased to a certain extent). After the test data is transmitted to the computer control system, the system activates the test alarm 1, which sounds a buzzer, and the motor 13 stops rotating. The operator then manually determines whether to replace the test material or component or stop the machine for the next test.

[0029] If an abnormality occurs during the test, the power motor 13 can be stopped by pressing the emergency stop button 11.

[0030] In summary, this utility model is not limited to the specific embodiments described above. Those skilled in the art can make various modifications and alterations without departing from the spirit and scope of this utility model. The scope of protection of this utility model should be determined by the claims of this utility model.
