[0003] For spring products to develop more in-depth, the fatigue testing process is very important, and the existing fatigue testing device can only test a single type of spring, and spot checks in daily production can still complete the task. However, in the research and development In the process, it is necessary to detect springs with different heights and strokes, but the existing fatigue detection device cannot detect springs with different heights and strokes, so it is necessary to provide a device that can perform fatigue detection on springs with different heights and strokes

Embodiment Construction
[0029] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other examples, some technical features known in the art are not described in order to avoid confusion with the present invention.
[0030] When the applicant researched the spring, it was found that the existing spring fatigue detection device can only detect a single type of spring, and spot checks in daily production can complete the task. However, during the research and development process, springs with different heights and strokes need to be tested However, the existing fatigue detection device cannot detect springs with different heights and strokes, so the applicant has developed a device that can perform fatigue detection on springs with different heights and strokes.

The invention discloses a spring fatigue detecting device and method, and belongs to the field of spring testing. The spring fatigue detecting device comprises a working table, a test board fixedly mounted on the upper portion of the working table, a height adjusting device fixedly mounted on one side of the test board, an electric motor mounted above the height adjusting device and an eccentric wheel assembly rotationally connected with the electric motor, the eccentric wheel assembly comprises a rotating wheel with one end rotatably connected with the electric motor, a linear motion mechanism fixedly mounted at the other end of the rotating wheel, a rotating shaft fixedly mounted on the linear motion mechanism, a moving block slidingly connected with the rotating shaft, a sliding assembly mounted at the two ends of the moving block, and a pressing plate mounted below the sliding assembly; the sliding assembly is fixedly connected with the working table, and the moving block is slidably connected with the working table. Accordingly, by changing the center distance of the eccentric wheel and the height from the eccentric wheel to the working table, fatigue testing can be conductedon springs of different heights and strokes.
Description
technical field [0001] The invention belongs to the field of spring testing, in particular to a spring fatigue detection device and a detection method. Background technique [0002] Although the spring is small, its role cannot be underestimated. The country's industrial manufacturing and automobile industries need to speed up the development, and the spring industry as one of the basic parts and components needs to have an advanced stage of development in order to adapt to the rapid development of the country's entire industry. In addition, the expansion of the scale and variety of spring products and the improvement of the quality level are also the needs of the replacement of mechanical equipment and the improvement of the performance of supporting hosts. Therefore, spring products play an important role in the development of the entire national industry. [0003] For spring products to develop more in-depth, the fatigue testing process is very important, and the existin...
