[0026] Reference Figure 2 The bottom end of the support block 4 is fixedly connected to the bottom end of the inner wall of the table body 1. The support block 4 here provides stable support for the bevel gear 1 3. The inner wall of the table body 1 is rotatably connected with a bidirectional threaded rod 5. The outer right side of the bidirectional threaded rod 5 is fixedly connected with a bevel gear 2 6. The bevel gear 1 3 and the bevel gear 2 6 are meshed. When the bevel gear 1 3 here rotates, it will drive the bevel gear 2 6 to rotate, thereby driving the bidirectional threaded rod 5 to rotate. Both sides of the outer side of the bidirectional threaded rod 5 are threadedly connected with moving blocks 7.

[0027] Reference Figure 2 The bottom end of the moving block 7 is slidably connected to the bottom end of the inner wall of the table body 1. The bidirectional threaded rod 5 here will drive the moving block 7 on it to move toward the center when it rotates. The top of the moving block 7 is rotatably connected to two connecting shafts 8. The moving block 7 here will drive the connecting shaft 8 to rotate when it moves. The other end of the connecting shaft 8 is rotatably connected to a ring 9. The top outside of the ring 9 is slidably connected to the top inner wall of the table body 1. The connecting shaft 8 here will drive the ring 9 on it to move toward the center when it rotates.

[0028] Reference Figure 2 Two sliding grooves 10 are provided at the front and rear ends of the inner wall of the table body 1. The inner walls of the two sliding grooves 10 are slidably connected to the limiting column 11. The sliding groove 10 here provides a sliding space for the limiting column 11. The inner wall of the ring 9 is slidably connected to the outside of the limiting column 11. The top of the ring 9 is fixedly connected with a splint 12, and the bottom end of the splint 12 is slidably connected to the top of the table body 1. The table body 1 here provides stable support for the splint 12, and the inner side wall of the splint 12 is rotatably connected to the electric roller 13.

[0029] Reference Figure 1-Figure 3 , the adjacent sides of multiple electric rollers 13 are slidably connected to the rail body, and the electric roller 13 here can drive the rail body to move to the left. This is the existing technology and will not be described here. A grinding assembly is fixedly connected to the left side of the top of the table body 1, and the grinding assembly includes a frame 14. The bottom end of the frame 14 is fixedly connected to the inner wall of the left side of the top of the table body 1. The grinding assembly here is used to fully grind the rail body, and the four sides of the inner wall of the frame 14 are fixedly connected with special-shaped blocks 15.

[0030] Reference Figure 3-Figure 4The outside of the special-shaped block 15 is rotatably connected to multiple grinding wheels 16, and the grinding wheels 16 here are used to grind the rail body. A cleaning component is fixedly connected to the left side of the top of the table body 1, and the cleaning component includes a frame 17. The four sides of the inner wall of the frame 17 are fixedly connected with inner blocks 18. The cleaning component here is used to clean and sweep away the debris on the rail body after grinding to prevent the accumulation of debris and thus affect the quality of the product. A groove 19 is opened inside the inner block 18, and a brush 20 is slidably connected to the inner wall of the groove 19. The brush 20 here is used to brush away the debris on the rail body.

[0031] Reference Figure 4 The outer wall of the brush 20 is fixedly connected to the limiting block 21, and the outer part of the limiting block 21 is slidably connected to the inner wall of the groove 19. The limiting block 21 here is used to limit the retraction range of the brush 20 and control its sliding range. A spring 22 is provided inside the groove 19, and one end of the spring 22 is fixedly connected to one side of the inner wall of the groove 19, and the other end of the spring 22 is fixedly connected to one side of the limiting block 21. The groove 19 and the limiting block 21 here provide stable support for the spring 22, so that it can operate stably.

[0032] Working principle: When using this device, the staff can first place the guide rail that needs to be polished on the top of the table body 1, and then start the motor 2 in the inner wall of the table body 1. At this time, the motor 2 will drive the bevel gear 1 3 to rotate. Because the bevel gear 1 3 is engaged with the bevel gear 2 6 on the two-way threaded rod 5, it will drive the bevel gear 2 6 to rotate. The support block 4 here plays a supporting role for the motor 2, making it more stable during operation. When the bevel gear 2 6 rotates, it will drive the two-way threaded rod 5 to rotate, and at the same time drive the two moving blocks 7 on it to move closer to the middle.

[0033] At the same time, it will drive the connecting shaft 8 on it to operate, and at the same time drive the ring 9 and the limiting column 11 sliding in the slide groove 10 to shrink toward the center, so as to drive the clamping plate 12 and the electric roller 13 on it to clamp toward the center until it firmly fixes the guide rail. Then, the electric roller 13 is controlled to drive the guide rail as a whole to move to the left. At this time, the grinding wheel 16 on the special-shaped block 15 is started, and the guide rail can be effectively and comprehensively polished when it passes through the frame 14.

[0034] After grinding is completed, the guide rail will continue to pass through the frame 17 on the left. At this time, the brush 20 will effectively intercept the grinding debris on its surface to prevent excessive accumulation of debris on it, thereby affecting the quality of the product. The limit block 21 here mainly serves as a limit for the brush 20 to prevent it from leaving the sliding range of the groove 19, and the spring 22 here makes it more thorough to clean the debris on the guide rail, further improving the quality of the product.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
