Description

Technical Field

[0001] This utility model relates to the technical field of spring machine turning devices, specifically a CNC spring machine turning device. Background Technology

[0002] The CNC spring machine transfer device is a functional component specially designed for CNC spring machines. It is mainly responsible for the rapid and accurate replacement and conveying rotation of steel wire during the spring manufacturing process. It is one of the key components for realizing the automation and high efficiency of spring manufacturing, which greatly improves the flexibility and production efficiency of spring manufacturing.

[0003] Existing CNC spring machine rotation devices generally rely solely on bearings at both ends for rotational support. While this design approach offers some advantages in cost control and manufacturing simplicity, it reveals significant shortcomings in stability. The poor stability stems primarily from the fact that bearings, as critical support points for rotating components, endure complex and variable loads and wear over extended periods. This performance degradation is particularly rapid during high-speed, high-precision spring manufacturing. Furthermore, the lack of sufficient rigidity and dynamic balancing mechanisms in the bearing support layout makes the rotation device prone to vibration and misalignment during operation. This not only affects the accuracy and quality of the finished springs but also accelerates the damage to bearings and connected components. Therefore, we propose a CNC spring machine rotation device. Utility Model Content

[0004] The purpose of this utility model is to provide a CNC spring machine turning device to solve the problem mentioned in the background art, which generally relies solely on bearings at both ends for rotational support. Although this design approach has some considerations in terms of cost control and ease of manufacturing, it has exposed obvious deficiencies in terms of stability. The main reason for the poor stability is that the bearings, as the key support points of the rotating parts, are subjected to complex and variable loads and wear over a long period of time. Especially in the high-speed, high-precision spring manufacturing process, their performance deteriorates particularly rapidly. In addition, the layout of the bearings at both ends lacks sufficient rigidity and dynamic balance adjustment mechanism, making the turning device prone to vibration and displacement during operation. This not only affects the accuracy and quality of the finished springs, but also accelerates the damage rate of the bearings and connected components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC spring machine winding device, comprising a housing, a rectangular groove formed at the center of the inner wall of the housing, an upper cavity and a lower cavity formed at the top and bottom of the housing, respectively, a winding device body disposed inside the rectangular groove, a first motor fixedly installed at the center of the top of the housing, a stud disposed at the center of the upper cavity, a screw plate threadedly connected to the center of the surface of the stud, vertical rods fixedly connected to the bottom of the screw plate on both sides, and stabilizing wheels fixedly connected to the lower ends of the two vertical rods and the bottom of the rectangular groove on both sides, wheel grooves formed on both sides of the surface of the winding device body, and guide rods fixedly installed at the four corners of the top of the upper cavity.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This CNC spring machine's winding device, through the design of its housing, first motor, stud, vertical rod, guide rod, wheel grooves, and stabilizing wheels, achieves flexible and stable rotation of the upper and lower stabilizing wheels within the two wheel grooves on the surface of the winding device's main body. This design not only provides strong support for the main body of the winding device, effectively preventing swaying and deviation during operation, thus ensuring the stability and accuracy of the winding process, but also, by precisely controlling the operation of the first motor, drives the stud to rotate, which in turn moves the stabilizing wheels on the screw plate and vertical rod up and down along the guide rod. This allows for precise adjustment of the pressure of the two top stabilizing wheels on the wheel grooves. This dynamic adjustment capability enables the main body of the winding device to maintain optimal stability and rotational efficiency under different loads and working conditions, exhibiting significant advantages in adaptability and flexibility. It also reduces friction and wear, decreases the burden on bearings, extends the service life of the equipment, and lowers maintenance costs. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a CNC spring machine wire-turning device, including a housing 1, a rectangular groove 2 is formed in the center of the inner wall of the housing 1, an upper cavity 5 and a lower cavity 15 are formed in the top and bottom of the housing 1 respectively, the wire-turning device body 3 is arranged inside the rectangular groove 2, a first motor 6 is fixedly installed in the center of the top of the housing 1, a stud 7 is arranged in the center of the upper cavity 5, a screw plate 8 is threadedly connected to the center position of the surface of the stud 7, vertical rods 9 are fixedly connected to the bottom of the screw plate 8 on both sides, the lower ends of the two vertical rods 9 are fixedly connected to the bottom of the rectangular groove 2 on both sides, wheel grooves 12 are formed in the surface of the wire-turning device body 3 on both sides, and guide rods 11 are fixedly installed in the top of the upper cavity 5 on all four corners.

[0015] Both ends of the main body 3 of the wire transfer device extend to the outside of the rectangular groove 2. A wire feeding device body 4 is provided on one side of the box 1. The wire feeding device body 4 is responsible for feeding the wire into the main body 3 of the wire transfer device through the internal transmission roller, so as to ensure a stable supply of wire.

[0016] Both sides of the housing 1 are provided with support frames 20. Bearings are fixedly installed on the top of the inner wall of the two support frames 20. The two ends of the main body 3 of the transfer device pass through to the outside of the two bearings respectively. The inner rings of the two bearings are fixedly connected to the outer wall of the main body 3 of the transfer device, so as to provide rotational support for the main body 3 of the transfer device.

[0017] The first motor 6 is fixedly connected to the main shaft through its bottom output end. The lower end of the main shaft passes through the interior of the upper cavity 5 and is fixedly connected to the top of the stud 7. The bottom of the stud 7 is movably connected to the bearing fixedly installed at the bottom center of the upper cavity 5. The stud 7 is driven to rotate stably by controlling the first motor 6.

[0018] Grooves 10 are provided on both sides of the bottom of the upper cavity 5. The bottom of the two stabilizing wheels 13 located at the top extends through the outside of the two grooves 10 and contacts the inner wall of the two wheel grooves 12 respectively. The top of the two stabilizing wheels 13 located at the bottom contacts the inner wall of the two wheel grooves 12 respectively. The grooves 10 are used to accommodate the two stabilizing wheels 13 at the top. The lower ends of the four guide rods 11 extend through the outside of the screw plate 8 and are fixedly connected to the bottom of the upper cavity 5. The screw plate 8 moves vertically along the guide rods 11 to ensure its stability.

[0019] A gear ring 14 is fixedly installed at the center of the surface of the main body 3 of the transfer device. A second motor 16 is fixedly installed on one side of the lower cavity 15. A reducer 18 is fixedly installed on the side of the lower cavity 15 corresponding to the second motor 16. A rotating rod 19 is provided on one side of the reducer 18. A gear 17 is fixedly installed on the surface of the rotating rod 19. The upper end of the gear 17 penetrates into the interior of the rectangular groove 2 and meshes with the bottom of the gear ring 14. The second motor 16 is fixedly connected to the main shaft through its output end on one side. The reducer 18 is fixedly connected to the input shaft and the output shaft through its input end and output end on both sides, respectively. The main shaft is fixedly connected to the side opposite to the input shaft, and the output shaft is fixedly connected to the side opposite to the rotating rod 19. One end of the rotating rod 19 is movably connected to a bearing fixedly installed at the top position on one side of the lower cavity 15 to control the rotation of the second motor 16. The second motor 16 causes the gear 17 to mesh with the gear ring 14 and rotate through the reducer 18, thereby driving the main body 3 of the transfer device to rotate.

[0020] The bottom of the housing 1, the main body of the wire feeding device 4, and the two support frames 20 are fixedly installed with bases.

[0021] Before the device is started, the first motor 6 drives the stud 7 to rotate in the upper cavity 5. Because the stud 7 and the screw plate 8 are connected by a threaded connection, the rotation of the stud 7 causes the screw plate 8 to move vertically along the guide rod 11. This movement of the screw plate 8 further drives the stabilizing wheel 13 downwards via the vertical rod 9, ensuring that the stabilizing wheel 13 is tightly fitted into the wheel groove 12. This provides strong support for the main body 3 of the wire feeding device, preventing swaying and offset during operation. After the device is started, the transmission rollers inside the main body 4 of the wire feeding device begin to move... The first motor is responsible for feeding the wire stably and continuously into the main body 3 of the wire transfer device, ensuring the continuity and stability of the wire supply. At this time, the second motor 16 drives the main shaft to rotate through its output end, which in turn drives the input shaft of the reducer 18 to rotate. The reducer 18 smoothly transmits power to the output shaft by reducing the speed and increasing the torque. The output shaft then drives the rotating rod 19, which is fixedly connected to it, to rotate. The gear 17 on the surface of the rotating rod 19 rotates with the rotation of the rotating rod 19 and meshes tightly with the bottom of the gear ring 14 on the surface of the main body 3 of the wire transfer device. Due to the meshing relationship between the gear 17 and the gear ring 14, the rotation of the gear 17 will drive the gear ring 14 and the entire main body 3 of the wire transfer device to rotate within the rectangular groove 2.

[0022] In summary, this CNC spring machine winding device, through the design of the housing 1, the first motor 6, the stud 7, the vertical rod 9, the guide rod 11, the wheel groove 12, and the stabilizing wheel 13, achieves flexible and stable rotation of the two stabilizing wheels 13 within the two wheel grooves 12 on the surface of the winding device body 3. This design not only provides strong support for the winding device body 3, effectively preventing swaying and deviation during operation, thus ensuring the stability and accuracy of the winding, but also, by precisely controlling the operation of the first motor 6, the stud 7 can be driven to rotate, thereby driving the stabilizing wheels 13 on the screw plate 8 and the vertical rod 9 to move up and down along the guide rod 11, achieving precise adjustment of the pressure of the two stabilizing wheels 13 on the wheel grooves 12. This dynamic adjustment capability allows the winding device body 3 to maintain optimal stability and rotation efficiency under different loads and working conditions, exhibiting significant advantages in adaptability and flexibility. It also reduces friction and wear, reduces the burden on bearings, extends the service life of the equipment, and lowers maintenance costs.
