Multiple evenly distributed support seats 3 are bolted to the bottom of the base 1 for supporting the base 1. A grinding mechanism 4 is located at the top of the base 1, at one end of the clamping seat 2, and is used to grind the inner wall of the heat exchange tube. It is suitable for grinding the inner walls of tubes of different specifications. The grinding mechanism 4 includes a rotating... The moving column 404 and the rotating column 404 are located at one end of the clamping seat 2. A grinding rod 5 is sleeved inside the rotating column 404. A rotating rod 409 is bolted to one side of the grinding rod 5. The rotating rod 409 is rotatably connected to the inner wall of the rotating column 404 through a bearing. A spur gear 408 is welded to the outer wall of the rotating rod 409. A rack 407 meshes with the bottom end of the spur gear 408. The horizontal movement of the rack 407 can drive the spur gear 408 to rotate. The rotation of the spur gear 408 can drive the rotating rod 409 to rotate. The rotation of the rotating rod 409 can drive the grinding rod 5 to rotate. Thus, the inner wall of pipes of different specifications can be ground by the rotating grinding rod 5.

[0023] The inner wall of the rotating column 404 is provided with a rotating groove 4041, which matches the rotation trajectory of the grinding rod 5. The rotating groove 4041 is used to maintain the stability of the grinding rod 5 when it rotates. There are two rotating rods 409, and the two rotating rods 409 are symmetrically distributed on both sides of the grinding rod 5. This structure can improve the stability of the grinding rod 5 when it rotates and provide stable support for the grinding rod 5.

[0024] A movable seat 406 is welded to one end of the rack 407. A first electric telescopic rod 405 is provided at the end of the movable seat 406 away from the rack 407. The movement of the output end of the first electric telescopic rod 405 can drive the movable seat 406 to move, and the movement of the movable seat 406 can drive the rack 407 to move. A fixed seat 4051 is fixed to the outer wall of the first electric telescopic rod 405 by bolts. The fixed seat 4051 is fixedly connected to the inner wall of the rotating column 404 by bolts. The fixed seat 4051 is used to support the first electric telescopic rod 405, thereby ensuring the stability of the first electric telescopic rod 405 during operation. A drive motor 403 is connected to the end of the rotating column 404 away from the clamping seat 2 by a coupling. A sliding seat 402 is fixed to the bottom end of the drive motor 403 by bolts. A second electric telescopic rod 401 is fixed to one end of the sliding seat 402 by bolts. A fixing block 4011 is fixed to the outer wall of 401 by bolts. The bottom end of the fixing block 4011 is fixedly connected to the base 1 by bolts. The fixing block 4011 is used to ensure the stability of the second electric telescopic rod 401 during operation. The movement of the output end of the second electric telescopic rod 401 can drive the sliding seat 402 to move. The movement of the sliding seat 402 can drive the drive motor 403 to move. The movement of the drive motor 403 can drive the rotating column 404 to move. The rotation of the output end of the drive motor 403 can drive the rotating column 404 to rotate. A protrusion 4021 is fixed to the bottom end of the sliding seat 402 by bolts. A sliding groove 101 is opened inside the base 1. The sliding groove 101 matches the movement trajectory of the protrusion 4021. The sliding groove 101 is used to ensure the stability of the horizontal movement of the sliding seat 402 and the protrusion 4021. The protrusion 4021 is used to support the sliding seat 402.

[0025] Working principle: During use, the operator checks whether the state of the grinding rod 5 needs to be adjusted according to the inner cavity specifications of the pipe to be ground. When the state of the grinding rod 5 needs to be adjusted, the first electric telescopic rod 405 is controlled to work. The output end of the first electric telescopic rod 405 moves, which drives the moving seat 406 to move. The moving seat 406 moves and drives the two racks 407 to move. The racks 407 move and drive the spur gear 408 to rotate. The spur gear 408 rotates and drives the rotating rod 409 to rotate. The rotating rod 409 rotates and drives the grinding rod 5 to rotate. When the grinding rod 5 rotates clockwise by a certain angle, the grinding rod 5 contacts the inner wall of the pipe to be ground. At this time, the first electric telescopic rod 405 can be controlled to stop working.

[0026] Secondly, after the grinding rod 5 contacts the inner wall of the pipe cavity, the drive motor 403 is controlled to work. The output end of the drive motor 403 rotates, which drives the rotating column 404 to rotate. The rotating column 404 rotates and drives the grinding rod 5 to rotate. The second electric telescopic rod 401 is controlled to work. The output end of the second electric telescopic rod 401 moves and drives the sliding seat 402 to move towards the end closer to the clamping seat 2. The movement of the sliding seat 402 drives the drive motor 403 and the rotating column 404 to move, which in turn drives the grinding rod 5 to move into the inner cavity of the pipe. The inner wall of the inner cavity is ground by the rotating grinding rod 5.

[0027] Finally, the movement of the output end of the second electric telescopic rod 401 can drive the grinding rod 5 to move through mechanical transmission. The rotation of the output end of the drive motor 403 can drive the grinding rod 5 to rotate through mechanical transmission, thereby grinding the inner wall of the pipe cavity. The movement of the output end of the first electric telescopic rod 405 can drive the grinding rod 5 to rotate through mechanical transmission, thereby adjusting the state of the grinding rod 5 so that the grinding rod 5 can contact and grind the inner wall of the pipe cavity of different specifications.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
