[0027] The cutting mechanism includes a hydraulic cylinder 17, a tool holder 18, a cutting tool 19, and a connecting block 20. The hydraulic cylinder 17 is located on the upper surface of the vertical chamber 3. The connecting block 20 is located on the upper surface of the tool holder 18. A sliding cavity is provided at the lower part of the tool holder 18. Guide grooves 21 are provided on both sides of the tool holder 18 located in the sliding cavity. The cutting tool 19 is movably located in the sliding cavity of the tool holder 18. The two sides of the cutting tool 19 are respectively engaged with locking bolts 22.

[0028] Working method and operating principle: First, pass the upper guide rod 7 through the guide hole of the connecting block 20, and pass the lower guide rod 6 through the guide blocks 23 on both sides of the tool holder 18. Then, fasten the connecting plate 24 to the ends of the upper guide rod 7 and the lower guide rod 6 with screws. Then, fasten the connecting plates 24 at both ends to the inner surface of the column and the chamber 3 with bolts. Install the cylinder 8 on the support frame 5 on the upper surface of the base 1, and then install the motor 9 in the chamber 3, and pass the output shaft of the motor 9 through the chamber 3. Connect the first mounting plate 10 to the piston rod of the cylinder 8 through the bearing 14, and then install the first clamping plate 11 on the outer surface of the first mounting plate 10 with bolts. Connect the second mounting plate 12 to the output shaft of the motor 9 and fasten it with bolts. Then, install the second clamping plate 13 on the outer surface of the second mounting plate 12 with bolts. At this time, the first positioning shaft 15 at the center of the first clamping plate 11 and the second positioning shaft 16 at the center of the second clamping plate 13 are on the same axis. The hydraulic cylinder 17 is installed on the upper surface of the vertical chamber 3, and the piston rod of the hydraulic cylinder 17 is fastened to the connecting block 20. The hydraulic cylinder 17 can drive the cutter holder 18 to slide laterally along the upper guide rod 7 and the lower guide rod 6. Before use, according to the inner diameter of the PU skateboard wheel, select a suitable first clamping plate 11 with a first positioning shaft 15 and a second clamping plate 13 with a second positioning shaft 16. At the same time, according to the outer diameter of the PU skateboard wheel, place the cutter 19 in the cutter holder 18 and adjust the corresponding height so that the cutting edge at the bottom of the cutter 19 is exactly matched with the outer periphery of the PU skateboard wheel. The position of the cutter 19 is fixed by the cooperation of the locking bolt 22 and the locking nut. During operation, the PU skateboard wheel is fitted onto the second positioning shaft 16. The cylinder 8 drives the second clamping plate 13 to move closer to the first clamping plate 11. The first positioning shaft 15 is inserted into the PU skateboard wheel. At the same time, the second clamping plate 13 and the first clamping plate 11 clamp the two sides of the PU skateboard wheel through the rubber layer. The motor 9 is started, and the motor 9 drives the PU skateboard wheel to rotate. The hydraulic cylinder 17 causes the cutter holder 18 to move along the upper guide rod 7 and the lower guide rod 6. With the cooperation of the cutter 19, the burrs on the surface of the PU skateboard wheel are cut off and removed. After completion, the motor 9 stops, the piston rod of the cylinder 8 is retracted, and the PU skateboard wheel is manually turned. The PU skateboard wheel rolls down the slope 4 of the base 1 and is collected. This utility model has a reasonable structure. The first clamping plate 11 is connected to the first mounting plate 10 by bolts, and the second clamping plate 13 is connected to the second mounting plate 12 by bolts. The cutting tool 19 is fastened to the tool holder 18 by locking bolts 22 and locking nuts. The height of the cutting tool 19 is adjustable, so the first clamping plate 11 and the second clamping plate 13 can be replaced according to different models of PU skateboard wheels, and the position of the cutting tool 19 can be adjusted, greatly improving flexibility and applicability. The base 1 is provided with a ramp 4 in the processing area to facilitate the collection of PU skateboard wheels, greatly improving convenience. An upper guide rod 7 is slidably engaged with the connecting block 20, and two lower guide rods 6 are slidably engaged with the guide blocks 23 on both sides of the tool holder 18, which greatly improves the stability of the tool holder 18 and ensures processing accuracy.
