The following describes each embodiment of the present invention in detail with reference to the drawings.

[0031] Embodiment 1:

[0032] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a mobile spring polishing device, including a base 4, a rotating seat 5 is installed on the upper surface of the base 4, and a damping ring is provided between the rotating seat 5 and the base 4. The top of the rotating seat 5 is fixedly connected with a support disc 10; and a bracket 1 fixed on the base 4, the top of the bracket 1 is fixed with a fixed post 21, the outer wall of the fixed post 21 is limited and rotated to install a mounting plate 20, and a plurality of grinding mechanisms are provided between the mounting plate 20 and the support disc 10; each grinding mechanism includes a rotating sleeve 12 rotatably installed on the support disc 10, and a telescopic airbag assembly is arranged on the top of the rotating sleeve 12 for limiting and fixing the spring body 22; and a mounting block 30 arranged on the mounting plate 20, a spline shaft 19 that can slide up and down is installed inside the mounting block 30, the bottom of the spline shaft 19 is provided with a mounting seat 18, and the bottom of the mounting seat 18 is fixed with two vertical rods 16. Limiting posts 17 are fixedly installed on the opposite surfaces of the two vertical rods 16, and a limiting groove 13 is opened on the rotating sleeve 12 for the limiting posts 17 to slide in it; it also includes a grinding disc assembly arranged on the upper parts of the two vertical rods 16 for grinding the spring body 22.

[0033] Such as Figure 1 , 7, as shown in Figures 8 and 9, by rotating the telescopic airbag assembly provided at the top of the rotating sleeve 12, the spring body 22 can be limited and fixed. Then, through the provided grinding disc assembly, it is made to fit the outer wall of the spring body 22. When the driving rotating sleeve 12 rotates, since a spline shaft 19 that can slide up and down is installed inside the mounting block 30, and two vertical rods 16 are fixed to the bottom of the mounting seat 18, with limit posts 17 fixedly installed on the opposite surfaces of the two vertical rods 16, and a limit groove 13 is formed in the rotating sleeve 12 for the limit post 17 to slide in. That is, when the rotating sleeve 12 rotates, under the combined action of the limit sliding of the limit groove 13 and the limit post 17, and the limit sliding of the spline shaft 19 on the mounting block 30, on the one hand, the rotation of the rotating sleeve 12 can drive the spring body 22 to rotate, and on the other hand, the rotation of the rotating sleeve 12 can drive the grinding disc assembly where the vertical rods 16 are located to move up and down, thereby enabling the outer wall of the spring body 22 to be polished efficiently in a rotational manner.

[0034] Furthermore, a planetary gear transmission mechanism is provided at the lower part of the support disc 10 for driving a plurality of rotating sleeves 12 to rotate. The planetary gear transmission mechanism includes a plurality of mounting columns 7, each mounting column 7 being fixedly connected to the bottom of the corresponding rotating sleeve 12, and a transmission tooth 9 being fixedly installed on the outer wall of the mounting column 7. It also includes a second motor 8 fixed to the middle of the base 4, and a second driving tooth 29 being fixedly installed on the output shaft of the second motor 8, with the second driving tooth 29 meshing and driving the transmission tooth 9.

[0035] Through the provided planetary gear transmission mechanism, since the second motor 8 is fixed to the middle of the base 4, and the second driving tooth 29 is fixedly installed on the output shaft of the second motor 8, plus the second driving tooth 29 meshes and drives the transmission tooth 9, as Figure 1 、 7 , as shown in Figures 8 and 9, when the second motor 8 operates, it can further drive the second driving tooth 29 thereon to rotate, and further drive the mounting column 7 where the transmission tooth 9 is located to rotate, thereby causing each rotating sleeve 12 to rotate.

[0036] Furthermore, the telescopic airbag assembly includes an elastic telescopic bag 15 fixed to the top of the rotating sleeve 12. A conduit is connected between the elastic telescopic bag 15 and the top of the mounting column 7, and the conduit penetrates through the inside of the rotating sleeve 12. A first piston plate is provided inside the mounting column 7, and a cylinder 6 is fixed to the bottom end of the mounting column 7 for driving the first piston plate to slide up and down inside the mounting column 7.

[0037] As Figures 1 to 9As shown in the figure, by means of the provided telescopic airbag assembly, the spring body 22 to be polished is sleeved on the outer wall of the elastic telescopic bag 15, and a conduit is connected between the elastic telescopic bag 15 and the top of the mounting post 7. In addition, a first piston plate is arranged inside the mounting post 7, and a cylinder 6 is fixed at the bottom end of the mounting post 7. When the cylinder 6 works, it can drive the first piston plate to slide up and down inside the mounting post 7. Due to the connection of the conduit, gas can be sucked into the elastic telescopic bag 15. Since the elastic telescopic bag 15 is made of elastic telescopic material, when gas is sucked into the elastic telescopic bag 15, the volume of the elastic telescopic bag 15 can change, so that the outer wall of the elastic telescopic bag 15 fits against the inner wall of the spring body 22, thus realizing the limit fixation of the spring body 22.

[0038] Embodiment 2:

[0039] Furthermore, a meshing transmission mechanism is arranged on the base 4 for driving the rotating seat 5 where the support disk 10 is located to rotate. The meshing transmission mechanism includes a first motor 2 fixed on the base 4, a first driving tooth 3 is fixed on the output shaft of the first motor 2, and teeth 11 meshing with the first driving tooth 3 are distributed on the outer wall of the support disk 10.

[0040] As Figure 1 shown in the figure, since the first driving tooth 3 is fixed on the output shaft of the first motor 2, when the first motor 2 works, because the teeth 11 meshing with the first driving tooth 3 are distributed on the outer wall of the support disk 10, the support disk 10 can overcome the damping effect between the rotating seat 5 and the base 4 and then rotate itself. As Figure 6 and 7 shown in the figure, at this time, the second driving tooth 29 on the second motor 8 remains fixed. When the support disk 10 rotates as a whole, it can drive the transmission tooth 9 to rotate circumferentially along the second driving tooth 29. At this time, the transmission tooth 9 rotates circumferentially and rotates on its own axis at the same time. Similarly, it can drive the grinding disk assembly where the vertical rod 16 is located to move up and down, so as to perform a dynamic grinding process on the outer wall of the spring body 22.

[0041] Furthermore, the limiting groove 13 is formed by connecting two V-shaped grooves end to end.

[0042] As Figure 8 shown in the figure, through the structural setting of the limiting groove 13, when the rotating sleeve 12 rotates, the up and down movement of the vertical rod 16 can be realized.

[0043] Embodiment 3:

[0044] Furthermore, the grinding disk assembly includes two electric telescopic rods 14 fixed on the inner wall of the vertical rod 16, and a grinding plate 27 is fixedly installed at the output end of the electric telescopic rod 14.

[0045] With the set grinding wheel assembly, since the output end of the electric telescopic rod 14 is fixedly installed with a grinding plate 27, when the electric telescopic rod 14 is driven to extend, the outer wall of the spring body 22 can be clamped and fixed by using the grinding plate 27.

[0046] As Figure 8 shown, further, a grinding layer is provided on the outer wall of the elastic expansion bladder 15. When the grinding plate 27 clamps and fixes the outer wall of the spring body 22, the grinding layer provided on the outer wall of the elastic expansion bladder 15 is made to fit with the inner wall of the spring body 22. Similarly, when the rotating sleeve 12 rotates, the grinding plate 27 where the vertical rod 16 is located can drive the spring body 22 to move up and down. By using the rotation of the rotating sleeve 12, the elastic expansion bladder 15 can be further driven to rotate. By using the grinding layer provided on the outer wall of the elastic expansion bladder 15, the inner wall of the spring body 22 can be efficiently ground.

[0047] Further, a piston cylinder 23 is rotatably installed in the middle of the support disk 10. A second piston plate 28 is slidably installed inside the piston cylinder 23. A fixed sleeve 31 fixed to the bottom of the fixed column 21. An activity rod 24 that can slide up and down is installed inside the fixed sleeve 31. The activity rod 24 extends into the piston cylinder 23 and is fixedly connected to the second piston plate 28, and a one-way liquid valve communicated with the bottom of the piston cylinder 23.

[0048] When the polishing agent is connected to the one-way liquid valve, when the second piston plate 28 moves up and down inside the piston cylinder 23, at this time, the inside of the piston cylinder 23 is continuously suctioned, and the nozzle where the piston cylinder 23 is located can be made to spray. Especially in Embodiment 2, that is, when the spring body 22 is in a dynamic grinding process, the grinding efficiency can be further improved.

[0049] Further, a connection ring 25 that can be rotationally limited is installed on the outer wall of the activity rod 24. Connecting rods 26 are respectively connected between the connection ring 25 and the top of each mounting seat 18.

[0050] As Figure 7 shown, by installing a connection ring 25 that can be rotationally limited on the outer wall of the activity rod 24, and connecting rods 26 are respectively connected between the connection ring 25 and the top of each mounting seat 18. When the rotating sleeve 12 rotates, the mounting seat 18 where the spline shaft 19 is located can be further driven to move up and down. Due to the connection of the connecting rod 26, the mounting seat 18 can be further driven to move up and down, so that the second piston plate 28 moves up and down inside the piston cylinder 23.

[0051] Working principle: During use, the spring body 22 to be polished is sleeved on the outer wall of the elastic telescopic bladder 15 through the provided telescopic bladder assembly. When the cylinder 6 works, it can drive the first piston plate to slide up and down inside the mounting column 7. Due to the connection of the conduit, gas can be sucked into the elastic telescopic bladder 15. Since the elastic telescopic bladder 15 is made of elastic telescopic material, when gas is sucked into the elastic telescopic bladder 15, the volume of the elastic telescopic bladder 15 can change, so that the outer wall of the elastic telescopic bladder 15 fits against the inner wall of the spring body 22, thus realizing the limit fixation of the spring body 22.

[0052] As Figure 1 , 7 , 8 and 9 show, through the provided grinding disc assembly, making it fit against the outer wall of the spring body 22, and through the provided planetary gear transmission mechanism, as Figure 1 , 7 , 8 and 9 show, when the second motor 8 works, it can further drive the second driving tooth 29 thereon to rotate, and further drive the mounting column 7 where the transmission tooth 9 is located to rotate, so that each rotating sleeve 12 rotates;

[0053] When driving the rotating sleeve 12 to rotate, when the rotating sleeve 12 rotates, under the limiting sliding of the limiting groove 13 and the limiting post 17, and the limiting sliding of the spline shaft 19 on the mounting block 30, on the one hand, the rotation of the rotating sleeve 12 can drive the spring body 22 to rotate, and on the other hand, the rotation of the rotating sleeve 12 can drive the grinding disc assembly where the vertical rod 16 is located to move up and down, so as to efficiently polish the outer wall of the spring body 22 in a rotary manner.
