[0022] In this embodiment, the base box 1 serves as the cornerstone of the entire device. Through its stable connection with the ground, it provides a solid installation foundation for other components. The installation of the mounting frame 2 and the protective box 18 on the top of the base box 1 not only ensures the precise operation of the detection components, but also provides safety protection; the precise positioning of the mounting frame 2 and the first electric hydraulic rod 3: the fixation of the mounting frame 2 on the top of the base box 1 ensures the vertical movement accuracy of the first electric hydraulic rod 3, thereby ensuring the stability and accuracy of the pressure plate 4 when applying force to the spring; the sophisticated design of the insertion rod 5: the diameter of the insertion rod 5 at the bottom of the pressure plate 4 is smaller than the inner diameter of the through hole 8, ensuring that the insertion rod 5 can be inserted into the spring without hindrance, achieving stable stretching, avoiding displacement of the spring during compression, and enhancing the stability and safety of the detection; the mounting plate 6 Efficient detection design of the placement tube 7: multiple placement tubes 7 on the mounting plate 6 allow multiple springs to be placed at the same time, and the mounting plate 6 is driven to rotate by the rotating mechanism, so that the spring in each placement tube 7 can be accurately detected, greatly improving the detection efficiency; the safety barrier of the protective box 18: the setting of the protective box 18 effectively prevents the splashing of fragments when the spring breaks, provides a safe working environment for the operator, and reduces the safety risks during the detection process; in summary, the spring fatigue detection device of the present invention, through the stable support of the base box 1, the precise control of the first electric hydraulic rod 3, the sophisticated design of the insertion rod 5, the efficient detection design of the mounting plate 6 and the placement tube 7, and the safety protection of the protective box 18, realizes the efficiency and safety of spring fatigue detection.

[0024] In this embodiment, the rotation mechanism achieves precise and smooth rotation of the mounting plate 6, thereby ensuring the continuity and accuracy of the inspection process. First, the assembly plate 9, serving as the base platform for the rotation mechanism, is cleverly positioned within the base box 1. This design not only fully utilizes the space within the base box 1 but also allows the assembly plate 9 to be height-adjustable. This crucial feature allows the height of the rotation mechanism to be flexibly adjusted to meet different inspection requirements, ensuring stable operation in all operating conditions. It also provides significant convenience and flexibility for the installation of subsequent components. The rotating shaft 11, a key component connecting the mounting plate 6 and the motor 12, is meticulously rotatably mounted on the assembly jig 10.

The ball 14 is cleverly embedded in the top of the bracket 13, forming a precise match with the annular groove opened at the bottom of the mounting plate 6. When the mounting plate 6 rotates under the drive of the motor, the ball 14 will roll freely in the annular groove, thereby improving the rotation smoothness.

[0027] In a further preferred embodiment of the present invention, a second electric hydraulic rod 15 is fixedly installed in the base box 1 for regulating the lifting and lowering of the assembly plate 9. An assembly block 16 is fixedly installed on the output rod of the second electric hydraulic rod 15.

The bolted connection also makes installation and removal of the groove block 17 and assembly block 16 simple and quick. When maintenance or replacement of the assembly plate 9 is required, the two can be easily separated by simply loosening the bolts, significantly simplifying the maintenance process.

[0031] In a further preferred embodiment of the present invention, a through opening is opened on the top of the base box 1 , and the inner diameter of the through opening is larger than the diameter of the assembly plate 9 , so that the assembly plate 9 can be inserted and exited.

[0033] In a further preferred embodiment of the present invention, the protective box 18 is provided with a take-in / put-out opening, and an openable / closable protective door 19 is provided in the take-in / put-out opening. The protective door 19 is hinged to the protective box 18 via a hinge 20 .

[0034] In this embodiment, the design of the access opening and protective door 19 allows operators to easily access, replace, or maintain internal components. The protective door 19 is hingedly connected to the protective box 18 via hinges 20. This connection is not only stable and reliable, but also allows for smoother opening and closing of the door. Operators simply open the door and complete the required operation through the access opening before closing it, making the entire process quick and convenient.

[0035] To sum up, through the stable support of the base box 1, the precise control of the first electric hydraulic rod 3, the ingenious design of the insertion rod 5, the efficient detection design of the mounting plate 6 and the placement tube 7, and the safety protection of the protective box 18, the efficiency and safety of the spring fatigue detection are achieved, and the safety problems currently faced by the spring fatigue detection equipment on the market in actual applications, especially the problem of fragments flying due to the breakage of the spring during the detection process, are solved. The bracket 13 not only firmly supports the entire rotating mechanism, but also the ball 14 cleverly arranged on the top forms a precise match with the annular groove at the bottom of the mounting plate 6. The use of the ball 14 significantly reduces the friction during the rotation of the mounting plate 6 and improves the smoothness of the rotation.
