[0017] Example 1

[0018] See also Figure 1-2 A device for removing rust from the surface of a metal pipe comprises a base 1, with first guide rails 2 provided on both sides of the base 1, and two first slides 3 slidably connected via the first guide rails 2. The base 1 is provided with a first driving mechanism that drives the two first slides 3 to move simultaneously relative to or in opposite directions. Specifically, the first driving mechanism comprises a first bearing seat 15 connected to both ends of the base, a first screw rod 16 rotatably connected to the two first bearing seats, a first motor 17 connected to the base, a first transmission shaft connected to the first motor via a coupling, a driving wheel 18 connected to the first transmission shaft, a driven wheel 19 connected to one end of the first screw rod, and a transmission belt 20 connected to the driving wheel and the driven wheel. The first screw rod 16 has oppositely directed threads on both sides, and the two first slides 3 are respectively threadedly connected to both sides of the first screw rod 16. When the first motor 17 is started, the driving wheel 18, the driven wheel 19, and the transmission belt 20 cooperate to drive the first screw rod 16 to rotate. During the rotation of the first screw rod 16, the two first slides 3 are driven to move relative to or in opposite directions, thereby adapting to pipes of different lengths.

[0019] A support base 4 is fixed on each of the two first slides 3, and a rotating shaft 5 is rotatably connected to each of the two support bases 4. The opposite ends of the two rotating shafts 5 are connected to a pneumatic chuck 6, and one of the support bases 4 is provided with a second driving mechanism for driving the rotating shaft 5 to rotate; the second driving mechanism is a second motor 21 installed on one of the support bases, and the second motor 21 is transmission-connected to the rotating shaft 5 on the support base 4.

[0020] A second slide 7 is slidably connected to the first guide rail 2 between the two first slides 3. A third drive mechanism is provided on the second slide 7 and the base 1 to drive the second slide 7 along the first guide rail 2. Specifically, the third drive mechanism includes a third motor 22 mounted on the second slide, a second transmission shaft connected to the third motor via a coupling, a gear 23 connected to the second transmission shaft, and a rack 24 connected to one side of the base and meshing with the gear. When the third motor 22 is activated, the gear rotates, and the gear, in conjunction with the rack, drives the second slide along the first guide rail to grind the pipe.

[0021] Second guide rails 8 are connected to both sides of the second slide 7, and a third slide 9 is slidably connected to the two second guide rails 8. A fourth drive mechanism is provided on the second slide 7 to drive the third slide 9 to slide along the second guide rails 8. Specifically, the fourth drive mechanism includes second bearing blocks 25 connected to both ends of the second slide, a second screw rod 26 rotatably connected to the two second bearing blocks, and a fourth motor mounted at one end of the second slide and drivingly connected to the second screw rod. The third slide 9 is threadedly connected to the second screw rod 26. When the fourth motor is activated, the second screw rod rotates, which in turn drives the third slide 9 to move along the second guide rails 8.

[0022] A collecting box 10 is connected to the second slide 7, and two baffles 11 are connected to one side of the collecting box 10. A conveying plate 12 is connected between the two baffles 11. A notch communicating with the conveying plate is provided on one side of the collecting box 10. The upper ends of the two baffles 11 are rotatably connected to a grinding wheel 13. A grinding motor 14 for driving the grinding wheel 13 to rotate is provided on one of the baffles 11. The grinding wheel 13 is located on one side between the two pneumatic chucks 6 so that the grinding wheel 13 contacts the pipe clamped by the pneumatic chuck.

[0023] The working principle of this embodiment is as follows: one end of a pipe 27 is fixed to one of the pneumatic chucks 6. The first motor 17 is then activated, which, through the cooperation of the driving pulley 18, the driven pulley 19, and the transmission belt 20, drives the first screw 16 to rotate. The rotation of the first screw 16 drives the two first slides 3 to move relative to each other until the pneumatic chuck at the other end clamps the other end of the pipe, thus stabilizing the pipe. The fourth motor is then activated to rotate the second screw 26. During this rotation, the third slide 9 moves along the second guide rail 8 toward the pipe until the grinding wheel 13 contacts the pipe. The grinding motor 14 is then activated to drive the grinding wheel 13 to grind the pipe. Simultaneously, the second motor 21 rotates the pipe, thereby grinding a section of the pipe's outer wall. After one revolution, the third motor 22 is activated again, driving the gear 23 to rotate. The gear 23, in cooperation with the rack 24, drives the second slide 7 along the first guide rail 2 to fully grind the pipe. While grinding, the debris falling from the pipe will fall down along the conveyor plate 12 into the collection box 10, and will not fall directly on the base 1, thereby reducing damage to the base and reducing pollution to the environment, and facilitating cleaning.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
