[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] A precast component grinding device, such as Figures 1-5 As shown, the device includes a protective frame 1, a support plate 2 fixedly connected inside the protective frame 1, a motor 3 fixedly connected to the support plate 2, a threaded rod 4 fixedly connected to the output shaft of the motor 3, a slider 5 threadedly connected to the threaded rod 4, a fixed plate 6 fixedly connected to the support plate 2, and several limiting rods 7 fixedly connected to the fixed plate 6. The limiting rods 7 are all slidably connected to the slider 5. The fixed plate 6 is provided with a grinding assembly for grinding. The grinding assembly includes a positioning plate 8 rotatably connected to the fixed plate 6, several connecting rods 9 fixedly connected to the positioning plate 8, a positioning ring 10 slidably connected to the several connecting rods 9, several spring telescopic rods 11 fixedly connected to the positioning rings 10, and a grinding block 12 detachably connected to the telescopic end of the spring telescopic rods 11. The positioning rings 10 are rotatably connected to the slider 5. The positioning plate 8, the threaded rods 4, and the protective frame 1 are provided with driving components that drive the positioning plate 8 to rotate.

[0018] like Figures 1-5 As shown, when grinding the carbon fiber tube, first press each grinding block 12 to compress the spring telescopic rod 11. Then, place the carbon fiber tube onto each grinding block 12 and make the bottom end of the carbon fiber tube contact the top surface of the protective frame 1. Since the grinding block 12 is no longer pressed at this time, the spring telescopic rod 11 will reset and cause the grinding block 12 to adhere to the inner wall of the carbon fiber tube. Then, hold the carbon fiber tube and start the motor 3 to drive the threaded rod 4 to rotate, thereby causing the slider 5 to slide on the limit rod 7. At the same time, the motor 3 will also drive the drive component to rotate the threaded rod 4 to rotate the carbon fiber tube. When the positioning plate 8 rotates, it will drive the connecting rod 9 and the positioning ring 10 to rotate. When the positioning ring 10 rotates, it will also drive the spring telescopic rod 11 and the grinding block 12 to rotate. At this time, the grinding block 12 will move spirally upward or spirally downward inside the carbon fiber tube to grind the carbon fiber tube. After grinding is completed, the motor 3 can be turned off and the carbon fiber tube can be removed. In this way, it does not require a large area to be used, and the spring telescopic rod 11 and the grinding block 12 can be used to grind carbon fiber tubes of different diameters, which is quite practical.

[0019] like Figure 1 , Figure 2 , Figure 4 As shown, a limit ring 13 is fixedly connected to the top of several connecting rods 9 to prevent the slider 5 and the positioning ring 10 from coming off.

[0020] like Figures 2-3As shown, the driving component includes a gear 14 fixedly connected to the positioning disk 8 and the threaded rod 4, and a gear 15 rotatably connected to the bottom side of the inner side of the protective frame 1. Both gears 14 mesh with gear 15. When the motor 3 drives the threaded rod 4 to rotate, the gear 14 connected to the threaded rod 4 will also rotate. Subsequently, this gear 14 will drive the gear 15 to rotate, and the gear 15 will then drive the other gear 14 to rotate. When the other gear 14 rotates, it will drive the positioning disk 8 to rotate.

[0021] like Figures 1-3 As shown, a suction plate 16 is fixedly connected to the top side of the inner side of the protective frame 1, and a suction machine 17 is fixedly connected to the protective frame 1. The suction machine 17 and the suction plate 16 are connected and communicate with each other through the connecting pipe 18. When grinding carbon fiber tubes, the suction machine 17 can be turned on. Then the suction machine 17 will draw away and store the carbon fiber dust that appears after grinding through the connecting pipe 18 and the suction plate 16, so as to prevent the dust from overflowing into the air and causing permanent damage to the workers by inhalation.

[0022] like Figure 5 As shown, the grinding block 12 has a groove 19 for inserting the telescopic end of the spring telescopic rod 11. When installing the grinding block 12, the grinding block 12 can be directly picked up and snapped onto the telescopic end of the spring telescopic rod 11. During grinding, the grinding block 12 will be pushed by the spring telescopic rod 11 and adhere to the inner wall of the carbon fiber tube, making it difficult to fall off. This method allows for quick assembly and disassembly of the grinding block 12, which is quite convenient.

[0023] Working principle: When polishing the carbon fiber tube, first turn on the suction machine 17, then press each polishing block 12 to compress the spring telescopic rod 11. Then, place the carbon fiber tube on each polishing block 12 and make the bottom end of the carbon fiber tube contact the top surface of the protective frame 1. Since the polishing block 12 is no longer pressed at this time, the spring telescopic rod 11 will return to its original position, causing the polishing block 12 to adhere to the inner wall of the carbon fiber tube. Then, hold the carbon fiber tube and start the motor 3 to drive the threaded rod 4 to rotate, which in turn drives the slider 5 to slide on the limit rod 7. At the same time, the motor 3 will also drive the gear 14 connected to the threaded rod 4 to rotate. Then, this gear 14 will drive the gear 2 15 to rotate, and the gear 2 15 will drive the other gear 14. The rotation of the motor 3 causes the positioning plate 8 to rotate, which in turn drives the connecting rod 9 and the positioning ring 10 to rotate. When the positioning ring 10 rotates, it also drives the spring telescopic rod 11 and the grinding block 12 to rotate. At this time, the grinding block 12 will move spirally upward or downward inside the carbon fiber tube to grind the carbon fiber tube. After grinding is completed, the motor 3 can be turned off and the carbon fiber tube can be removed. This method can avoid occupying a large area and can grind carbon fiber tubes of different diameters by using the spring telescopic rod 11 and the grinding block 12. It is quite practical. The carbon fiber dust produced by grinding can also be collected by the suction machine 17 to prevent the dust from overflowing into the air and causing permanent damage to the workers by inhalation.
