[0027] The lower side of the mounting plate 3 is provided with a first milling cutter 2, one side of the first milling cutter 2 is fixedly provided with a hinge 202, and the side away from the first milling cutter 2 is fixedly provided with a second milling cutter 204. The first milling cutter 2 and the second milling cutter 204 are in the shape of an arch. The inner walls of the first milling cutter 2 and the second milling cutter 204 are provided with pre-milling cutters 205 near the two ends. Three groups of discharge ports 207 are formed in the inner part of the first milling cutter 2 and the second milling cutter 204 at the side and top positions. The inner walls of the first milling cutter 2 and the second milling cutter 204 are provided with face milling cutters 206 at the edge positions of the discharge ports 207. The lengths of the three groups of face milling cutters 206 gradually increase. The first milling cutter 2 can cooperate with the second milling cutter 204 to process the surface of the track 1. During the processing, the first milling cutter 2 and the second milling cutter 204 can be flipped around the hinge 202, so that the first milling cutter 2 and the second milling cutter 204 can push the components on the inner side to adhere to the track 1, thereby ensuring effective processing of the track 1 and preventing the device from not being in contact with the track 1 enough to cause poor processing results. The discharge ports 207 can discharge the waste inside the first milling cutter 2 and the second milling cutter 204, thereby avoiding friction between the device and the track 1 that affects the surface treatment effect of the track 1. The face milling cutters 206 are provided in three groups, and the lengths of the three groups of face milling cutters 206 gradually increase. The three groups of face milling cutters 206 respectively contact the track 1 to process the surface of the track 1 to different degrees, thereby ensuring the processing effect of the device on the surface of the track 1 and avoiding the single group of blades from being easily damaged due to excessive force during processing to improve the durability of the device.
[0028] The inner side of the first milling cutter 2 and the second milling cutter 204 is slidably provided with the track 1.

The limiting ring 203 is an arc-shaped rod with the same arc as the sleeve 201. One end of the limiting ring 203 is fixedly connected to the top of the second milling cutter 204. The sleeve 201 and the limiting ring 203 can cooperate with each other to limit the first milling cutter 2 and the second milling cutter 204, so that the first milling cutter 2 and the second milling cutter 204 can only be flipped through the hinge 202, avoiding the first milling cutter 2 and the second milling cutter 204 from being offset to the two sides of the track 1, thereby ensuring the processing effect of the first milling cutter 2 and the second milling cutter 204 on the track 1 and improving the overall processing precision of the device on the track 1.

The mounting seat 302 and the fixing bolts 303 can connect the mounting plate 3 with a driving device, so that the device can slide along the track 1 by the driving device after being connected with the driving device, and the device can process the surface of the track 1.
[0032] Further, the inner wall of the first milling cutter 2 and the second milling cutter 204 is provided with a bevel, and the bevel is arranged between the edge of the pre-milling cutter 205 and the first milling cutter 2 or the second milling cutter 204. By arranging the bevel between the pre-milling cutter 205 and the cutting edge, the first milling cutter 2 and the second milling cutter 204 can be guided, and the first milling cutter 2 and the second milling cutter 204 can be guided to smoothly slide along the extension direction of the track 1 when the first milling cutter 2 and the second milling cutter 204 slide along the track 1, so that the cutting edge is prevented from being scratched on the track 1, and the smoothness of the first milling cutter 2 and the second milling cutter 204 during the sliding process is ensured.
[0033] Further, the discharge port 207 is an inclined square groove, and the slope of the discharge port 207 is the same as the slope of the face milling cutter 206.
[0034] Working principle: after the driving device is connected to the mounting seat 302 through the fixing bolts 303, the first milling cutter 2 and the second milling cutter 204 are clamped on the top of the track 1, the device is moved as a whole by the driving device, the first milling cutter 2 and the second milling cutter 204 slide along the track 1 at a constant speed, during the sliding process, the pre-milling cutter 205 first contacts the track 1 and processes the surface of the track 1, then the three groups of face milling cutters 206 with different lengths are sequentially contacted with the track 1 to process the surface of the track 1 three times, the solid waste generated during the processing is discharged from the first milling cutter 2 and the second milling cutter 204 through the discharge port 207, and finally the pre-milling cutter 205 on the other side is contacted with the track 1 again to process the track 1 for the last time, so that the adhering objects or uneven areas on the surface of the track 1 are trimmed to be flat, and the surface processing of the track 1 is completed.
