[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0037] Please see Figures 1 to 6 This utility model provides a technical solution:

[0038] A stone railing polishing machine includes a mounting frame 1, wherein the mounting frame 1 is specifically structured as two cylinders, and fixing plates are fixedly mounted on the top and bottom of the two cylinders, such as... Figure 2 As shown, a fixing plate 3 is then fixedly installed on the two cylinders at the lower end of the mounting bracket 1. The lower end of the fixing plate 3 is a certain distance from the ground. Then, the main motor 301 is fixedly installed at the center of the lower end of the fixing plate 3. The lower end of the main motor 301 is flush with the lower end of the mounting bracket 1 to ensure that the mounting bracket 1 will not tilt. Figure 2 As shown, the output shaft of the main motor 301 passes through the fixed disk 3, and the upper diameter of the output shaft is slightly larger. Two symmetrical adjusting screws 302 are rotatably mounted near the edge of the upper end face of the main motor 301 output shaft. Each adjusting screw 302 has a V-shaped clamping rod 303 rotatably mounted on its adjacent end. When the two adjusting screws 302 rotate, and the adjacent ends, along with the rotatably connected V-shaped clamping rods 303, gradually reduce the distance between them, the railing post 4 placed on the upper end face of the main motor 301 output shaft can be fixed, ensuring that the railing post 4 is in a vertical position and preventing tilting or collapse during subsequent rotation. Figure 1 As shown.

[0039] A forward and reverse motor 2 is fixedly mounted at the center of the upper end face of the mounting bracket 1. The output shaft of the forward and reverse motor 2 extends to the inner side of the two cylinders of the mounting bracket 1, and a threaded rod 201 is fixedly mounted at the lower end of the output shaft of the forward and reverse motor 2. A sliding seat 202 is threadedly mounted on the circumferential surface of the threaded rod 201. The sliding seat 202 has a semi-circular structure and protrudes outward on its outer circumferential surface. The protruding part is slidably mounted on the outer surface of the two cylinders of the mounting bracket 1. Figure 1 As shown.

[0040] During use, the output shaft of the forward and reverse motor 2 rotates synchronously with the threaded rod 201. When the threaded rod 201 rotates, it can make the sliding seat 202 slide up and down, but it will not rotate synchronously with the threaded rod 201 due to the restriction of the mounting bracket 1.

[0041] like Figure 3 and Figure 4 As shown, two first motors 204 are fixedly installed on the upper surface of the front opening of the sliding seat 202. A first gear 205 is fixedly installed on the output shaft of the first motor 204. Then, a convex groove 203 is formed inside the sliding seat 202. An arc-shaped toothed ring 206 is rotatably installed inside the convex groove 203. The outer side of the arc-shaped toothed ring 206 has tooth grooves and meshes with the first gear 205. It should be noted that the front opening of the arc-shaped toothed ring 206 extends to the outer side of the sliding seat 202.

[0042] During use, the first motor 204 is started, and the output shaft of the first motor 204 drives the first gear 205 to rotate. Under the action of the tooth groove, the first gear 205 can make the arc-shaped toothed ring 206 rotate.

[0043] like Figure 5 As shown, a mounting plate 207 is fixedly installed inside the arc-shaped toothed ring 206. The upper surface of the mounting plate 207 is concave. A gear ring 208 is rotatably mounted inside the mounting plate 207. The outer side of the gear ring 208 is in contact with the inner wall of the mounting plate 207. Four second gears 212 are evenly rotatably mounted in a circular array inside the gear ring 208 on the inner bottom surface of the mounting plate 207. Each second gear 212 meshes with the tooth grooves on the inner side of the gear ring 208. Four through-slots 209 are formed on the inner bottom surface of the mounting plate 207, distributed inside the second gears 212. Figure 5 As shown, a sliding column 211 is slidably installed inside the sliding groove 209. A polishing stone 210 is fixedly installed on the upper end face of the sliding column 211. The outer side of the polishing stone 210 is toothed and meshes with the second gear 212. It should be noted that the polishing stones 210 are evenly distributed in a rectangular array, and the inner side of the polishing stone 210 is made of frosted material, so that the railing post 4 can be polished. In addition, the inner side of the polishing stone 210 can be recessed outward to a certain distance after contacting the railing post 4, so as to facilitate the polishing operation of the cylindrical railing post 4. The lower end face of the mounting plate 207 is in a through state to the inner center position.

[0044] In addition, a second motor 213 is fixedly installed on the lower end face of the mounting plate 207. The output shaft of the second motor 213 is fixedly connected to the lower end of one of the second gears 212. Therefore, during use, the output shaft of the second motor 213 drives the fixedly connected second gear 212 to rotate. When the second gear 212 rotates, it drives the gear ring 208 to rotate. When the gear ring 208 rotates, it can drive the other three second gears 212 to rotate. Therefore, the sliding column 211 on the lower end face of the polishing stone 210 that meshes with the second gear 212 slides inside the sliding groove 209, thereby changing the size of the inner side of the polishing stone 210.

[0045] Working principle: First, place the railing post 4 on the upper end face of the output shaft of the main motor 301, rotate the adjusting screw 302, and the adjusting screw 302, along with the V-shaped clamping rod 303, fixes the railing post 4.

[0046] Then, start the forward and reverse motor 2. The output shaft of the forward and reverse motor 2 drives the threaded rod 201 to rotate. When the threaded rod 201 rotates, it can make the sliding seat 202 move up and down. When the sliding seat 202 moves, it can drive the arc-shaped toothed ring 206 to move synchronously. The arc-shaped toothed ring 206 can drive the mounting plate 207 to rotate synchronously. The mounting plate 207 can drive the gear ring 208, the polishing stone 210, the second gear 212, and the second motor 213 to move synchronously.

[0047] The second motor 213 is started, and the output shaft of the second motor 213 drives the fixedly connected second gear 212 to rotate, thereby causing the gear ring 208 to drive the other three second gears 212 to rotate, so that the polishing stone 210 can slide under the action of the slide column 211.

[0048] Then start the main motor 301. The output shaft of the main motor 301 drives the railing post 4 to rotate, while the sliding seat 202 moves up and down, thereby polishing the outer surface of the railing post 4.

[0049] In addition, when the first motor 204 is started, the output shaft of the first motor 204 drives the first gear 205 to rotate. The first gear 205 drives the arc-shaped toothed ring 206 to rotate synchronously with the mounting plate 207, so that the rotation direction of the mounting plate 207 is opposite to the rotation direction of the main motor 301, thereby improving the grinding efficiency.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
