[0002] As an indispensable basic component in mechanical engineering, springs play an important role in various industrial equipment, especially in precision manufacturing, electronics, automobiles and other industries. With the continuous improvement of industrial automation, higher requirements are placed on the assembly accuracy and efficiency of springs. Traditional spring assembly mostly relies on manual operation, which is not only inefficient, but also prone to quality problems, such as incomplete spring expansion and loose assembly. In recent years, with the rapid development of intelligent manufacturing technology, automated spring assembly equipment has gradually become an industry trend. This type of equipment usually integrates functions such as precision positioning, automatic feeding, and visual inspection, which can greatly improve production efficiency while ensuring assembly accuracy.

[0003] However, although automation technology has made significant progress in the field of spring assembly, there are still some technical bottlenecks. Among them, the rebound phenomenon caused by the release of elastic potential energy during the spring installation process is one of the key factors affecting the assembly quality and efficiency. The rebound of the spring may not only cause damage to the components, but also cause equipment failure and even threaten the safety of the operator. Therefore, how to effectively control the rebound of the spring and achieve safe and stable spring installation has become an important issue that needs to be solved in this field. Therefore, we propose an anti-rebound spring installation fixture and a guide head spring assembly mechanism. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. During the spring installation process, when the spring is released from the compressed state to the natural state, it will rebound strongly due to the sudden release of elastic potential energy, which not only affects the assembly accuracy, but may also damage the components or fixtures, and even endanger the safety of the operator. By setting an anti-rebound plate above the support ring and utilizing the characteristics of the torsion spring around the rotating shaft, the impact force when the spring is released can be absorbed and buffered. Specifically, the torsion spring is compressed during the spring installation process. When the spring is installed in place, the torsion spring slowly releases energy to prevent the spring from rebounding. This design ensures the stability and safety of the spring during the installation process and improves the consistency and efficiency of assembly.

[0013] 2. The linkage of the Y-axis screw conveyor and the X-axis screw conveyor, as well as the coordinated use of the cylinder and the suction head, enable the spring assembly to be accurately grasped, positioned and placed in three-dimensional space. This highly automated material handling system greatly improves the flexibility and production efficiency of the assembly line, while also reducing labor costs and labor intensity.

[0021] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, an anti-rebound spring sleeve fixture provided by an embodiment of the utility model includes a rotating disk 13, a plurality of mounting molds 9 are fixedly connected to the upper part of the rotating disk 13, the mounting mold 9 includes a sleeve 93, the upper part of the sleeve 93 is fixedly connected to a support ring 92 through a connecting rod, an anti-rebound plate 91 is provided on the upper part of the support ring 92, a rotating shaft 95 is provided on the lower part of the anti-rebound plate 91, a sleeve 96 is sleeved on the outer side of the rotating shaft 95, and a torsion spring is provided on the left and right sides of the sleeve 96 respectively.

[0023] The torsion spring is sleeved on the rotating shaft 95 , the left and right sides of the rotating shaft 95 are respectively fixedly connected to the limit plates, the lower part of the sleeve 96 is fixedly connected to the support ring 92 , and the upper part of the rotating disk 13 is fixedly connected to the support rod 94 .

[0024] In the spring sleeve operation, the rebound of the spring is a common problem, especially in the automated production line. The sudden rebound of the spring not only affects the assembly efficiency, but also may pose a safety hazard to the equipment and operators. The core purpose of the utility model is to design an anti-rebound spring sleeve fixture to effectively suppress the rebound in the spring sleeve process, ensure the stability and safety of the assembly process, and thus improve production efficiency and product quality.

[0025] The rotating plate 13 is used as a basic platform for carrying the installation mold 9. Its design takes into account the application requirements of the spring sleeve fixture on the automated production line. The introduction of the rotating plate 13 enables multiple installation molds 9 to operate synchronously, thereby improving production efficiency.

[0026] Each mounting mold 9 is composed of a sleeve 93, a support ring 92, an anti-rebound plate 91, a rotating shaft 95, a sleeve 96 and a torsion spring, which together form a complete spring sleeve unit. Such a modular design is conducive to rapid adjustment and replacement according to springs of different specifications, and enhances the versatility and flexibility of the fixture.

[0027] The combination of the anti-rebound plate 91 and the torsion spring is the innovation of the utility model, which is intended to control the rebound force during the spring installation process. The torsion spring is fixed below the support ring 92 through the rotating shaft 95. When the spring is installed, the torsion spring is compressed to store energy; after the spring is installed, the torsion spring slowly releases energy to buffer the rebound of the spring, thereby achieving a smooth installation process.

[0028] Through the coordinated work of the anti-rebound plate 91 and the torsion spring, the impact force generated by the spring during the release process is effectively absorbed and alleviated, the instability and potential risks caused by the spring rebound are avoided, and the accuracy and success rate of the spring sleeve are improved.

[0029] The utility model also discloses a guide head spring assembly mechanism, including an anti-rebound spring sleeve fixture and a main body 6, the interior of the main body 6 is fixedly connected with a stepper motor, and the output shaft of the stepper motor passes through the top of the main body 6 and is fixedly connected to the lower part of the rotating disk 13.

[0030] Two heightening blocks 7 are fixedly connected to the upper part of the main body 6, and a column 1 is fixedly connected to the upper part of the heightening block 7. A top frame 2 is welded to the upper part of the column 1, and the top frame 2 is connected to the mounting plate 3 by bolts. A switch 4 is provided on the heightening block 7.

[0031] The lower part of the mounting plate 3 is fixedly connected to a Y-axis screw conveyor 8, the lower part of the sliding seat of the Y-axis screw conveyor 8 is fixedly connected to an X-axis screw conveyor 12, the lower part of the sliding seat of the X-axis screw conveyor 12 is fixedly connected to a cylinder 10, and the lower end of the piston rod of the cylinder 10 is fixedly connected to a suction head 11.

[0032] A material box 14 is provided on the upper part of the main body 6 , a magnet block is embedded in the lower part of the material box 14 , and an inspection door 5 is rotatably connected to the right side of the main body 6 .

[0033] The utility model aims to provide a pilot head spring assembly mechanism, which realizes high-precision and high-efficiency spring automatic assembly by integrating anti-rebound spring sleeve fixtures and automatic components, while ensuring the safety of operation and the stability of assembly. On the basis of the existing technology, the rotating disk 13 driven by the stepper motor is combined with the multi-axis linkage material conveying system, which solves the problems of low efficiency, poor precision, and insufficient safety in traditional manual or semi-automatic spring assembly.

[0034] The main body 6 is the main frame of the entire assembly mechanism, and the built-in stepper motor is used to accurately control the rotation of the rotating disk 13 to ensure the accurate positioning of the spring sleeve fixture. The use of stepper motors provides higher positioning accuracy and controllability than ordinary motors, and is the key to achieving automated assembly.

[0035] The configuration of the double-axis screw conveyor realizes the precise movement of materials in the plane. In conjunction with the cylinder 10 and the suction head 11, the spring and other components can be automatically grasped and placed, greatly improving the automation and accuracy of assembly.

[0036] A magnet block is embedded at the bottom of the material box 14, which is adsorbed on the iron main body 6 by magnetism, ensuring the stability and orderliness of the material, reducing production interruptions caused by the movement of the material box 14, and improving the continuity and efficiency of the production line.
