[0002] A spring is a mechanical part that generates force or stores energy by deforming itself. It is used for buffering, absorbing vibration, and controlling mechanical motion, or as a power source for instruments and clocks. It can also be used as a force measuring element. Commonly used springs in machinery can be classified according to the nature of the force they are subjected to, such as tension springs, compression springs, torsion springs, and bending springs. According to their shape, they can be classified as helical springs, planar spiral springs, torsion bar springs, leaf springs, disc springs, and ring springs. Because it is necessary to ensure that springs have good performance during use, mechanical springs need to be tested for fatigue during production using testing devices.

Furthermore, the sizes and lengths of the springs to be tested vary, making it difficult to test springs of different sizes.

The top of the fixing block 21 extends into the inner cavity of the rotating rod 3 and is threadedly connected to the surface of the threaded rod 31. The fixing block 21 slides in the inner cavity of the rotating rod 3. A sliding table 4 is provided on the top of the main body 1 of the testing machine. The sliding table 4 slides left and right on the top of the main body 1 of the testing machine. Specifically, an I-shaped guide rail 8 is fixedly mounted on the top of the main body 1 of the testing machine. A roller assembly 9 is provided on the top of the guide rail 8. The roller assembly 9 slides left and right on the top of the I-shaped guide rail 8. The sliding table 4 is fixedly installed on the top of the roller assembly 9. Specifically, the roller assembly 9 includes a mounting frame 91. An upper roller 92 is rotatably connected to the top of the inner cavity of the mounting frame 91. Lower rollers 93 are rotatably connected to both the front and rear ends of the bottom of the inner cavity of the mounting frame 91. Both the upper roller 92 and the lower roller 93 roll on the surface of the I-shaped guide rail 8. A fixing post 94 is welded to the top of the mounting frame 91. A limit nut 95 is threaded onto the surface of the fixing post 94. The sliding table is secured by the limit nut 95. 4. Locked at the top of the mounting bracket 91, the top of the rotating rod 3 is rotatably connected to the telescopic rod 5. The end of the telescopic rod 5 away from the rotating rod 3 is rotatably connected to the top of the sliding table 4. Specifically, anti-detachment fixing posts 11 are fixedly installed at one end of the top of the rotating rod 3 and the middle of the top of the sliding table 4. The two ends of the telescopic rod 5 are respectively rotatably connected between the two anti-detachment fixing posts 11. A fixed platform 6 is movably installed at the right end of the top of the main body 1 of the testing machine. Specifically, a plug rod 61 is welded to the bottom of the fixed platform 6. The top of the I-shaped guide rail 8 has multiple mounting slots 81 that cooperate with the plug rod 61. 61 is locked in the inner cavity of the mounting groove 81 by a nut. Clamping components 7 are provided on the opposite sides of the sliding table 4 and the fixed table 6. The clamping components 7 fix the spring body 10 between the sliding table 4 and the fixed table 6. Specifically, the clamping components 7 include a bidirectional threaded rod 71 that rotates on the opposite side of the fixed table 6 and the sliding table 4. A slide groove 74 is provided on the opposite side of the fixed table 6 and the sliding table 4. Two sliders 72 are slidably connected in the inner cavity of the slide groove 74. Anti-disengagement hooks 73 are fixedly installed on the opposite side of the sliders 72.

[0029] The rotating rod 3 is located at the top of the I-shaped guide rail 8, and the I-shaped guide rail 8 does not affect the rotation operation of the rotating rod 3; the telescopic rod 5 is an existing telescopic rod locking structure, which can flexibly adjust the distance between the two anti-detachment fixing posts 11 according to the spring's time length, thereby achieving the purpose of detecting spring bodies 10 of different lengths.

[0030] Working principle: When using this utility model, the user places the two ends of the spring body 10 onto the surfaces of the anti-disengagement hooks 73 in the two clamping assemblies 7, and rotates the bidirectional threaded rod 71 to drive the two anti-disengagement hooks 73 to slide in opposite directions, so that the anti-disengagement hooks 73 internally support and hook the spring body 10. At this time, the slider 72 will slide in the inner cavity of the slide groove 74, thereby locking the spring body 10 between the sliding table 4 and the fixed table 6. Then, according to the testing requirements, the threaded rod 31 is rotated to drive the rotating rod 3 to slide on the top of the rotating column 2 to adjust the stretching amplitude of the spring body 10. Finally, the testing machine body 1 is started, so that the rotating column 2 rotates at a relatively uniform speed on the top of the testing machine body 1, thereby pulling the sliding table 4 and the roller assembly 9 to slide back and forth on the top of the I-shaped guide rail 8 to perform fatigue testing on the spring body 10. The testing machine body 1 can record the number of stretching times of the spring body 10 and the total monitoring time.

[0031] In summary, this spring fatigue testing device for spring production, through the sliding connection of the rotating rod 3 to the top of the rotating column 2, allows for the adjustment of the testing amplitude of spring bodies 10 of different sizes according to requirements when testing them. Furthermore, it reduces the space occupied by the rotating rod 3, making the overall testing device compact and cost-effective.
