[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 2The utility model provides an embodiment: a spring fatigue detection device for spring production, comprising a base 1, a connecting column 2 is rotatably connected to the upper surface of the base 1, a fan-shaped plate 3 is fixedly connected to the side wall of the connecting column 2, a slide groove 4 is provided inside the fan-shaped plate 3, a fixing rod 5 is fixedly connected to the upper surface of the base 1, the inner wall of the slide groove 4 is slidably connected to the outer wall of the fixing rod 5, a connecting piece 6 is fixedly connected to the upper surface of the fan-shaped plate 3, a connecting pipe 7 is fixedly connected to the side wall of the connecting piece 6, a coil spring 8 is fixedly connected to one end of the connecting pipe 7, a rotating plate 9 is rotatably connected to the side wall of the fan-shaped plate 3, and the side wall of the rotating plate 9 is fixedly connected to one end of the coil spring 8, a fixing plate 10 is fixedly connected to the upper surface of the base 1, a thimble 11 is arranged on the side wall of the fixing plate 10, and a fixing component is arranged on the upper surface of the base 1.

[0023] Specifically, the movement of the connecting column 2 triggers the synchronous rotation of the fan plate 3, while the internal slide groove 4 ensures the stable movement of the fan plate 3. At the same time, it is limited by the fixed rod 5 to avoid rotation beyond the specified range. When the rotating plate 9 rotates to the inside of the spring frame 12, the spring frame 12 will push the spring to the surface of the rotating plate 9 through its own rotation, preparing for the next operation. The rotation of the connecting column 2 again resets the fan plate 3, and at the same time, the ejector pin 11 on the fixed plate 10 applies pressure to firmly fix the spring on the rotating plate 9. This process ensures that the spring can be accurately fed into the detection system to prepare for subsequent fatigue detection. When the fan plate 3 is out of the pressure range of the ejector pin 11, the design of the coil spring 8 comes into play, which can help the rotating plate 9 quickly reset to the position for the next loading without manual intervention. Such a structural design makes the entire spring fatigue detection process more efficient and greatly improves the spring processing efficiency.

[0024] Reference Figure 3 The fixing assembly includes a spring frame 12, the bottom of the spring frame 12 is rotatably connected to the upper surface of the base 1, the top of the base 1 is rotatably connected to a gear 13, the top of the base 1 is fixedly connected to a gear 2 14, the gear 13 is meshed with the gear 2 14, the side wall of the gear 13 is rotatably connected to a connecting rod 15, the side wall of the connecting rod 15 is rotatably connected to a connecting rod 2 16, the side wall of the connecting rod 2 16 is rotatably connected to a connecting rod 3 17, the side wall of the connecting rod 3 17 is fixedly connected to a connecting shaft 18, one end of the connecting shaft 18 is fixedly connected to a connecting frame 20, the side wall of the connecting frame 20 is fixedly connected to a rotating rod 19, the side wall of the rotating rod 19 is rotatably connected to the side wall of the connecting shaft 18, one end of the rotating rod 19 is rotatably connected to the connecting frame 20, the outer wall of the connecting shaft 18 is slidably connected to a sliding column 21, the outer wall of the sliding column 21 is fixedly connected to a screw 22, one end of the connecting shaft 18 is fixedly connected to the screw 22, and the outer wall of the screw 22 is threadedly connected to a slide 23.

[0025] Specifically, the driving device causes the gear 13 to start rotating, and the gear 2 14 is driven to rotate through the meshing relationship. When the gear 13 and the gear 2 14 rotate, the side wall of the connecting rod 15 also starts to rotate and changes its tilt angle. This movement is converted through the connection of the connecting rod 15 to the connecting rod 2 16, so that the connecting rod 2 16 also undergoes the same movement and changes its tilt angle. The movement of the connecting rod 2 16 causes the bottom connecting rod 3 17 to be displaced, thereby affecting the connecting shaft 18 to follow the displacement, thereby achieving the sliding of the connecting shaft 18 inside the sliding column 21. At the same time, the rotation of the connecting rod 15 also causes the rotating rod 19 to rotate and change its tilt angle. This movement is transmitted to the connecting frame 20 through the rotating rod 19, causing the displacement of the connecting frame 20. In this way, the sliding column 21 will also be displaced, thereby driving the connecting shaft 18 to drive the slide 23 to stretch and compress the outer wall of the spring at the top. By adjusting the screw 22, the horizontal position of the screw 22 can be controlled, thereby adjusting the degree of stretching and compressing the spring. This design makes the spring fatigue test more comprehensive and can be flexibly adjusted for different spring types and requirements. The design of the entire system enhances the detection strength of the test equipment and improves its practicality.

[0026] Working principle: When the fatigue test of the spring is required, the spring is first placed in the spring frame 12, and then the driving device drives the connecting column 2 to rotate on the surface of the base 1. When the connecting column 2 rotates, the fan-shaped plate 3 on its side wall is driven to rotate synchronously. When the fan-shaped plate 3 rotates, the internal slide groove 4 slides on the outer wall of the fixed rod 5. The fixed rod 5 limits the fan-shaped plate 3 so that its rotation distance does not exceed the limited range. When the rotating plate 9 on the side wall of the fan-shaped plate 3 rotates into the spring frame 12, the spring frame 12 rotates to push the spring to the surface of the rotating plate 9, and then the connecting column 2 drives the fan-shaped plate 3 to rotate and reset again, and at the same time, the ejector pin 11 on the side wall of the fixed plate 10 presses down the spring on the surface of the rotating plate 9, so that the rotating plate 9 rotates on the side wall of the fan-shaped plate 3, so that the spring enters the detection system. At the same time, when the fan-shaped plate 3 leaves the pressing range of the ejector pin 11, the spiral spring 8 can help the rotating plate 9 to quickly reset for the next loading, and the loading can be performed without manual intervention. This structure makes the spring fatigue detection more efficient and improves the spring processing efficiency. After the spring enters the detection system, the driving device rotates the gear 13, and the gear 1 3 rotates, and the meshing relationship between the gear 13 and the gear 2 14 drives the gear 2 14 to rotate as well. When the gear 13 and the gear 2 14 rotate, the connecting rod 15 on the side wall rotates and changes its own tilt angle. The connecting rod 15 then drives the connecting rod 2 16 on the side wall to do the same movement to change the tilt angle. The connecting rod 2 16 can drive the bottom connecting rod 3 17 to move, and the connecting rod 3 17 then affects the connecting shaft 18 to follow the displacement, so that the connecting shaft 18 slides inside the sliding column 21. At the same time, the rotation of the connecting rod 15 drives the rotating rod 19 It rotates and changes the tilt angle, thereby driving the rotating rod 19 on its side wall to change the tilt angle, thereby driving the connecting frame 20 to move, and then the sliding column 21 is also moved, so that the sliding column 21 and the connecting shaft 18 can drive the slide 23 to repeatedly stretch and compress the spring on its outer wall at the top, and at the same time, the horizontal position of the screw 22 can be adjusted by adjusting the screw 22 to achieve different degrees of movement effects, so that the detection of spring fatigue is more comprehensive. Therefore, the structure improves the detection strength of this detection equipment and increases its practicality.
