DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Please refer to Figures 1 - 4, the present utility model provides a technical solution: a grinding mechanism for the inner wall of an automobile intake pipe, including: two discs 1, a first gear 14 and a second gear 16 are rotatably connected between the two discs 1, and the outer walls of the first gear 14 and the second gear 16 are meshed and connected. A fixed sleeve 2 is fixedly installed at the center of the outer end of the other disc 1. A driving shaft 3 is inserted into the fixed sleeve 2. The driving shaft 3 is fixed in the fixed sleeve 2 by bolts. The driving shaft 3 is connected to an external driving mechanism. The device is driven to rotate by the external driving mechanism. A motor 4 is fixedly installed at the outer end of the other disc 1. The output end of the motor 4 is fixedly connected to the center of one end of the second gear 16. The motor 4 is a servo motor and can rotate forward and backward. The motor 4 functions to drive the second gear 16 to rotate. When the second gear 16 rotates, it will drive the first gear 14 to rotate.

[0022] A number of strip-shaped holes 15 are evenly formed on the side wall of the first gear 14. The strip-shaped holes 15 are arc-shaped. A sliding column 7 is slidably connected in each strip-shaped hole 15. A driving rod 6 is fixedly installed at the outer end of the sliding column 7. The driving rod 6 is slidably connected to the inner wall of one of the discs 1. When the motor 4 drives the first gear 14 to rotate, the first gear 14 will drive the strip-shaped holes 15 to rotate synchronously. The arc-shaped strip-shaped holes 15 will drive the sliding column 7 to drive the driving rod 6 to move. A number of groups of limiting plates 5 are evenly fixedly installed on the inner wall of one of the discs 1. Each group has two. The driving rod 6 is slidably connected between the two limiting plates 5. When the driving rod 6 moves, it will slide within the two limiting plates 5, functioning to limit the driving rod 6.

[0023] A push plate 8 is fixedly installed at the outer end of the driving rod 6. An installation block 9 is elastically connected to the outer end of the push plate 8. A number of springs 10 are evenly fixedly installed between the push plate 8 and the installation block 9. One end of the spring 10 is fixedly installed at the upper end of the push plate 8, and the other end of the spring 10 is fixedly installed at the lower end of the installation block 9. The installation block 9 can move at the outer end of the push plate 8 by squeezing the spring 10, enabling the brush bristles 13 to fit more closely to the inner wall of the automobile pipe fitting. An elastic plate 11 is installed at the outer end of the installation block 9 through a fastening bolt 12. Brush bristles 13 are evenly fixedly installed at the outer end of the elastic plate 11. When the driving rod 6 moves, it will drive the push plate 8, the installation block 9, the elastic plate 11, and the brush bristles 13 to move synchronously, allowing the brush bristles 13 to expand and contract between the two discs 1, thereby meeting the requirement of grinding the inner walls of pipe fittings of different sizes.

[0024] The outer end of the installation block 9 is arc-shaped, and the elastic plate 11 is arc-shaped. The arc shape fits the inner wall of the pipe fitting better. Circular holes are formed at the left and right ends of the elastic plate 11, and threaded holes are formed at the left and right ends of the installation block 9. One end of the fastening bolt 12 passes through the through hole and is threadedly connected to the inner wall of the threaded hole, facilitating the disassembly and replacement of the brush bristles 13.

[0025] In actual use, one end of the drive shaft 3 is connected to an external drive mechanism, and then the other end of the drive shaft 3 is inserted into the fixed sleeve 2 and fixed by bolts. Then, the device is inserted into the inner end of the automotive pipe fitting to be polished. The motor 4 is started to drive the second gear 16 and the first gear 14 to rotate, driving the drive rod 6 to move the brush bristles 13 outward until they contact the inner wall of the pipe fitting. Then, the external drive mechanism is started to drive the device to rotate, and the inner wall of the pipe fitting can be polished.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
