The transmission block 9 is threadedly connected to the first threaded rod 8 and is movably inserted into a through hole of a suitable size on the support frame 2. The bottom end of the transmission block 9 is fixedly connected to the lifting component 26. The first motor 7 drives the first threaded rod 8 to rotate, which causes the transmission block 9 to drive the lifting component 26 and the driving device to move. The grinding wheel 14 moves on the channel steel to achieve the grinding work on the channel steel.

[0027] The driving device includes a mounting frame 10, a second motor 11, and a second threaded rod 12. The top end of the mounting frame 10 is fixedly connected to the bottom end of the lifting component 26. The second threaded rod 12 is rotatably connected to the mounting frame 10. The two ends of the second threaded rod 12 are respectively provided with left and right threads. Two transmission plates 3 are respectively threaded to the left and right threads of the second threaded rod 12. The size of the transmission plates 3 is adapted to the inner cavity size of the mounting frame 10. The second motor 11 is fixed on the mounting frame 10. The output end of the second motor 11 is fixedly connected to the second threaded rod 12. The grinding motor 13 is placed between the two clamping frames 4. The second motor 11 drives the second threaded rod 12 to rotate, so that the two transmission plates 3 move closer to each other. The transmission plates 3 drive the two clamping frames 4 to move, thereby realizing the clamping work of the grinding motor 13.

[0028] The grinding component includes a grinding motor 13 and a grinding wheel 14. The output end of the grinding motor 13 is fixedly connected to the grinding wheel 14. The two clamping frames 4 are provided with slots for the output end of the grinding motor 13 to pass through.

The bottom end of the third threaded rod 16 is rotatably connected to the scraper 6, and the bottom end of the guide rod 17 is fixedly connected to the scraper 6. Rotating the third threaded rod 16 causes the scraper 6 to move down and contact the worktable 1.

[0032] The working principle of this utility model is as follows: When using the device, the grinding motor 13 is placed between the two clamping frames 4. The second motor 11 drives the second threaded rod 12 to rotate, causing the two transmission plates 3 to move closer together. The transmission plates 3 drive the two clamping frames 4 to move, thus clamping the grinding motor 13. The channel steel is placed on the worktable 1, and the fifth threaded rod 24 is rotated, causing the two positioning plates 25 to move closer together, thus positioning the channel steel. The lifting component 26 drives the mounting frame 10 to move down, so that the grinding wheel 14 contacts the top of the channel steel. At this time, the mounting frame 10 can be moved down further according to the grinding needs, so that the spring 5 is compressed to a certain extent, thereby changing the grinding force of the grinding wheel 14 and improving the flexibility of the device. Next, the fourth threaded rod 20 is rotated, causing the guide frame 21 and multiple guide rollers 22 to move. The guide rollers 22 contact the side wall of the channel steel. The first motor 7 drives the first threaded rod 8 to rotate, causing the transmission block 9 to drive the lifting component 26 and the drive device to move. The grinding wheel 14 moves on the channel steel to achieve the grinding work on the channel steel. After grinding for a certain period of time, a lot of debris will accumulate on the worktable 1. At this time, the third threaded rod 16 can be rotated, causing the scraper 6 to move down. The scraper 6 contacts the worktable 1. The rotation of the first motor 7 drives the scraper 6 to move along the worktable 1 to scrape off the debris on the worktable 1. The debris is pushed by the scraper 6 to the discharge hole 18. A collection box can be placed below the discharge hole 18 to collect the debris.
