[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment of an automotive load-bearing spring assembly tool, comprising a base plate 1 and a spring load-bearing component 2. The lower end of the base plate 1 is provided with a universal wheel 3 with a built-in self-locking structure. A support seat 4 is fixedly connected to the upper end of the base plate 1, and the spring load-bearing component 2 is mounted on the upper end of the support seat 4. An automotive spring 5 is sleeved on the outer wall of the spring load-bearing component 2. A limiting rope 6 for binding the automotive spring 5 is provided on the side end of the support seat 4. Clamping assemblies for fixing the spring load-bearing component 2 are provided on the left and right sides of the upper end of the base plate 1. A lifting assembly is provided at the upper end of the base plate 1, located on one side of the clamping assembly. A limiting assembly for fixing the automotive spring 5 is provided at the lifting end of the lifting assembly. The limiting assembly compresses the automotive spring 5 through the lifting assembly. The base plate 1 serves as the basic support structure of the entire assembly tool. The universal wheel 3 with a built-in self-locking structure is specially designed at the lower end of the base plate 1, making... The entire tool can move flexibly and stop stably in the required position. The self-locking structure ensures that the tool will not slip accidentally in the working state. The spring carrier 2 is a component specially designed to support and position the car spring 5. The support seat 4 provides a stable support surface, allowing the spring carrier 2 to be firmly installed on it. The side end of the support seat 4 is equipped with a limiting rope 6 for binding the car spring 5, which helps to keep the spring stable during assembly and prevent it from shaking. The clamping assembly is used to fix the spring carrier 2 during assembly and prevent it from moving when subjected to spring pressure, thereby ensuring the safety of assembly. The lifting assembly is used to realize the compression operation of the car spring 5. The limiting assembly provides additional support and limiting function when the lifting assembly compresses the car spring 5 to prevent the car spring 5 from shaking during compression.

[0022] Please see Figure 1 and Figure 3 In this embodiment, the clamping assembly includes a support plate 7. The upper end of the base plate 1 is fixedly connected to the support plate 7. A screw hole is opened in the support plate 7, and a fixing screw 8 is threaded into the screw hole. One end of the fixing screw 8 is provided with a first knob 9, and the other end of the fixing screw 8 is provided with a clamping plate 10. A first bearing seat 11 is provided in the clamping plate 10, and the first bearing seat 11 is rotatably connected to the fixing screw 8. The clamping plate 10 has an arc-shaped structure, and the inner wall of the clamping plate 10 is provided with a rubber block that is adapted to the lower outer wall of the spring bearing member 2. The support plate 7 is a sturdy plate structure that serves as a support for the clamping assembly. The basic fixing screw 8 is a long, threaded rod. The function of fixing screw 8 is to move it within the screw hole by rotating knob 9, thereby adjusting the distance between clamping plate 10 and spring support 2, and thus clamping spring support 2. Clamping plate 10 is an arc-shaped plate that matches the shape of spring support 2. On the inner wall of clamping plate 10, a rubber block that fits the lower outer wall of spring support 2 is specially provided. The rubber block has excellent elasticity and wear resistance, which can provide additional cushioning and friction during clamping, ensuring that spring support 2 is firmly clamped.

[0023] Please see Figure 1 and Figure 4 In this embodiment, the lifting assembly includes a vertical plate 12, which is fixedly connected to the upper end of the base plate 1. A limit plate 13 is provided at one end of the vertical plate 12. The top of the vertical plate 12 and the upper end of the base plate 1 are both provided with the same No. 2 bearing seat 14. A lead screw 15 is rotatably connected inside the No. 2 bearing seat 14. A lifting seat 16 is threadedly connected to the outer wall of the lead screw 15. A drive shaft 17 is provided at the side end of the vertical plate 12. A crank handle 18 is provided at the end of the drive shaft 17. A transmission structure is provided between the drive shaft 17 and the lead screw 15. The transmission structure includes a driving bevel gear 19. The driving bevel gear 19 is fixedly connected to the outer wall of the drive shaft 17. A driven bevel gear 20 is fixedly connected to the outer wall of the lead screw 15. The driving bevel gear 19 and the driven bevel gear 20 are meshed. A slide rail 21 is provided on the inner wall of the side end of the vertical plate 12. A slider 22 adapted to the slide rail 21 is provided at one end of the lifting seat 16. The slider 22 slides. Connected to the slide rail 21, the vertical plate 12 serves as the support frame for the lifting assembly. The second bearing seat 14 provides stable rotational support for the lead screw 15, allowing it to rotate freely in the vertical direction. The lead screw 15 is a long, threaded rod that passes through the second bearing seat 14 at the top and bottom of the vertical plate 12 and is rotatably connected to it. The outer wall of the lead screw 15 is designed with threads that match the threaded groove in the lifting seat 16. When the lead screw 15 rotates, it can drive the lifting seat 16 to move up and down in the vertical direction. The drive shaft 17 is a shaft component that connects the crank handle 18 and the lead screw 15, ensuring that the lead screw 15 can be smoothly driven to rotate when the crank handle 18 is cranked. When the drive shaft 17 rotates, it can drive the driven bevel gear 20 and the lead screw 15 to rotate synchronously. The slider 22 is slidably connected to the slide rail 21, providing additional support and guidance for the lifting seat 16 and ensuring stability during the lifting process.

[0024] Please see Figure 1 and Figure 5In this embodiment, the limiting component includes a rotating plate 23. The left and right sides of the lifting seat 16 are provided with identical grooves 24. A fixed shaft 25 is fixedly connected within the grooves 24. The rotating plate 23 is sleeved on the outer wall of the fixed shaft 25. A limiting hook 26 is provided at the end of the rotating plate 23 facing the spring. A limiting screw 27 is threadedly connected to the rotating plate 23. A second knob 28 is provided at one end of the limiting screw 27, and a pressure block 29 is provided at the other end. The rotating plate 23 is a plate-shaped structure capable of rotating around the fixed shaft 25. The rotation of the rotating plate 23 via the fixed shaft 25... The function is to provide a limit hook 26 that can be adjusted in position and angle to contact and restrain the car spring 5. The limit hook 26 is a protrusion of the end of the rotating plate 23 facing the spring. It is designed in a curved shape to lock the car spring 5. The limit screw 27 is a rod-shaped component threaded into the rotating plate 23. By rotating the second knob 28, the limit screw 27 can be driven to move within the rotating plate 23, so that the pressure block 29 will apply a certain pressure to the car spring 5, thereby ensuring that the car spring 5 can be firmly held in the required position.

[0025] In the workflow, firstly, the spring carrier 2 is placed on the receiving seat 4. Then, the first knob 9 is rotated, which drives the fixing screw 8 to rotate and move forward, thereby causing the clamping plate 10 to tighten the spring carrier 2. Next, the car spring 5 is fitted onto the carrier and secured with the limiting rope 6. After that, the rotating plate 23 is rotated, causing the limiting hook 26 to firmly hook the car spring 5. Next, the second knob 28 is rotated, and its rotation drives the limiting screw 27 to rotate and move forward, thereby causing the pressure block 29 to apply appropriate pressure to the car spring 5. After ensuring the spring is securely fixed, the drive shaft 17 is rotated by turning the crank handle 18, which in turn drives the driving bevel gear 19 to rotate. Utilizing the meshing between the gears, the driven bevel gear 20 and the lead screw 15 rotate accordingly. Through the interaction between the threads, the lifting seat 16 can move vertically, thereby achieving smooth compression of the spring. At the same time, the slider 22 slides smoothly on the slide rail 21, providing additional support and guidance for the lifting seat 16 and ensuring the stability of the lifting process. Finally, the clamping plate of the spring carrier 2 is fixed by the nut.

[0026] Through the above steps, compared with the traditional electromechanical assembly method, this solution, through the coordinated work of the clamping component, lifting component, and limiting component, can not only smoothly compress the automotive spring 5 to the required height, greatly simplifying the assembly steps and improving work efficiency, but also flexibly adjust the position of the limiting hook 26 to ensure that the spring is tightly fitted and stably supported. Compared with the traditional fixed limiting method, this design can better meet the assembly requirements of springs of different specifications, thereby further enhancing the versatility and flexibility of the assembly. It solves the problem that although the traditional electromechanical assembly of automotive load-bearing springs has achieved automation, the process is complex, the adaptability is poor, the space occupied is large, and the cost is high, which limits its widespread application.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
