[0023] 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.

[0024] Reference Figure 1-3 , an embodiment provided by the utility model: a double-sided spring grinding machine, including a base 1, a support column 10 is fixedly connected to the center of the top of the base 1, a fixed disk 11 is fixedly connected to the top of the support column 10, a rotating disk 7 is rotatably connected to the top of the fixed disk 11, a motor 13 is fixedly connected inside the support column 10, the output end of the motor 13 is fixedly connected to the bottom of the rotating disk 7, a rotating block 8 of an annular array is rotatably connected inside the rotating disk 7, a left-right symmetrical slider 15 is fixedly connected to one side of the outer wall of the rotating block 8, a V-shaped groove 14 is opened on one side of the interior of the fixed disk 11, the slider 15 is slidably connected inside the V-shaped groove 14, an elastic gasket 12 is fixedly connected to the interior of the rotating block 8, a top plate 2 is fixedly connected to the top of the base 1, and a left-right symmetrical grinding wheel 16 is arranged at the bottom of the top plate 2;

[0025] Specifically, the rotating disk 7 is an important component driven by the motor 2 13. It is located on the top of the fixed disk 11 and drives the rotating block 8 to rotate. Slide blocks 15 are provided on its inner wall. These slide blocks 15 slide symmetrically at the bottom of the fixed disk 11 to ensure the horizontal movement of the rotating block 8. When the slide block 15 slides to the V-shaped groove 14, the slide block 15 on one side will slide into the V-shaped groove 14 to rotate the rotating block 8, and the slide block 15 on the other side will be tilted due to the rotation of the rotating block 8, so that it will not enter the V-shaped groove 14. This design makes it possible for the slide block 15 on the other side to slide out only when the slide block 15 is located in the V-shaped groove 14, so that the rotating block 8 can continue to rotate. As the rotating block 8 rotates, the spring fixed on the internal elastic gasket 12 will also rotate accordingly, and two grinding wheels 16 will grind the two sides of the spring respectively.

[0026] Reference Figure 1 and Figure 4 A clamping assembly is provided on one side of the interior of the top plate 2, and the clamping assembly includes an electric push rod 17 and a push plate 18. The outer wall of the electric push rod 17 is fixedly connected to the interior of the top plate 2, and the top of the push plate 18 is fixedly connected to the output end of the electric push rod 17. A feed box 3 is fixedly connected to one side of the top of the top plate 2, and a chuck 19 is rotatably connected to one side of the interior of the feed box 3. A motor 4 is fixedly connected to one side of the outer wall of the feed box 3, and one side of the outer wall of the chuck 19 is fixedly connected to the output end of the motor 4. A limited block 20 is fixedly connected to one side of the interior of the feed box 3, and a feeding pipe 6 is fixedly connected to the bottom of the feed box 3;

[0027] Specifically, first, the spring is placed in the feed box 3 to ensure that the spring can enter the next link in an orderly manner. Then, the chuck 19 starts to rotate through the drive of the motor 4. At this time, the spring will fall from the feed box 3 into the transverse groove on the surface of the chuck 19. As the chuck 19 continues to rotate, the spring will rotate with it. During the rotation, the chuck 19 will pass through the limit block 20. The function of the limit block 20 is to limit the rotation range of the chuck 19 to ensure that only a single spring in the transverse groove can pass through. In this way, the orderly arrangement and transportation of the springs can be achieved. Through this series of rotation and transportation, the spring will eventually fall into the feeding tube 6. In the feeding tube 6, the spring will continue to move downward and eventually be discharged between the elastic gaskets 12 inside the rotating block 8. At this time, the rotating block 8 starts to move and passes through the bottom of the push plate 18. The electric push rod 17 immediately drives the push plate 18 to press down, pressing the spring into the elastic gasket 12. The function of the elastic gasket 12 is to clamp the spring to ensure that it will not shift or loosen during the processing process.

[0028] Reference Figure 1 and Figure 5 A water tank 5 is fixedly connected to one side of the top of the top plate 2, a nozzle 21 is fixedly connected to one side of the inside of the top plate 2, an input end of the nozzle 21 is fixedly connected to the inside of the water tank 5, a motor 3 24 is fixedly connected to one side of the inside of the top plate 2, a driving wheel 25 is fixedly connected to the output end of the motor 3 24, a driven wheel 27 is rotatably connected to one side of the top of the top plate 2, a belt 26 is provided between the driving wheel 25 and the driven wheel 27, a slide bar 28 is slidably connected to the inside of the belt 26, a connecting rod 23 is fixedly connected to the top of the slide bar 28, an electric push rod 22 is fixedly connected to one side of the inside of the top plate 2, an output end of the electric push rod 22 is fixedly connected to one side of the bottom of the electric push rod 22, and a mechanical claw 9 is fixedly connected to the bottom of the slide bar 28;

[0029] Specifically, after the spring is polished, it will be sent to a special device for cooling. There is a nozzle 21 at the bottom of this device. The nozzle 21 quickly cools the spring by extracting the coolant inside the water tank 5. This cooling method can effectively prevent the spring from deforming at high temperatures and ensure its accuracy and stability. After cooling, the spring will be sent to the next process. In this process, the electric push rod 22 plays a key role. It controls the sliding of the slide bar 28 through the connecting rod 23, so that the mechanical claw 9 at the bottom of the slide bar 28 can be raised and lowered. The design of this mechanical claw 9 is very clever. It can accurately control the position of the spring to ensure its stability and safety during the transportation process. Next, the motor 3 24 starts working, it drives the active wheel 25 to rotate, and the active wheel 25 then drives the driven wheel 27 to rotate through the belt 26. As the driven wheel 27 rotates, the slide bar 28 will rotate accordingly, which allows the mechanical claw 9 at the bottom of the slide bar 28 to rotate. This rotation design allows the spring to be smoothly taken out of the rotating block 8 and transported to the next process.

[0030] Working principle: When grinding the spring, first put the spring into the feed box 3, and then the motor 4 drives the chuck 19 to rotate, and the spring will fall into the transverse groove on the surface of the chuck 19, and then rotate with the chuck 19, the chuck 19 will pass through the limit block 20. Under the restriction of the limit block 20, only the spring in the transverse groove can pass, and only a single spring can be placed in the transverse groove, thereby realizing the arrangement and transportation of the spring, and then with the rotation of the chuck 19, it falls into the feeding tube 6, and finally is discharged into the elastic gasket 1 inside the rotating block 8 through the feeding tube 6. 2, but when the rotating block 8 moves past the bottom of the push plate 18, the electric push rod 17 drives the push plate 18 to press down, and the push plate 18 presses the spring into the elastic gasket 12, and the elastic gasket 12 clamps the spring. The rotating disk 7 is driven by the motor 2 13 and rotates on the top of the fixed disk 11, so that the rotating disk 7 can drive the rotating block 8 to rotate, and a slider 15 is provided on the inner wall of the rotating block 8. Two symmetrical sliders 15 slide on the bottom of the fixed disk 11 to ensure the horizontal movement of the rotating block 8. When the slider 15 slides to the V-shaped slide groove 14 , the slider 15 on one side will slide into the V-shaped groove 14, so that the rotating block 8 rotates, while the slider 15 on the other side will be tilted due to the rotation of the rotating block 8, so that it will not enter the V-shaped groove 14. When the slider 15 on this side passes through the V-shaped groove 14, the slider 15 located inside the V-shaped groove 14 will slide out, so that the rotating block 8 rotates, so that the spring fixed by the elastic gasket 12 inside the rotating block 8 rotates, and the two grinding wheels 16 can grind the two sides of the spring respectively. After the spring grinding is completed, it will be The spring passes through the bottom of the nozzle 21, so that the cooling liquid inside the water tank 5 is extracted by the nozzle 21 to cool the spring. Then the electric push rod 22 can control the sliding of the slide bar 28 through the connecting rod 23, so that the mechanical claw 9 at the bottom of the slide bar 28 can be raised and lowered. Then the motor 3 24 drives the driving wheel 25, so that the driving wheel 25 drives the driven wheel 27 to rotate through the belt 26. Then the slide bar 28 will rotate with the driven wheel 27, so that the mechanical claw 9 at the bottom of the slide bar 28 can rotate, and the spring fixed in the rotating block 8 can be taken out and transported to the next process.
