Specifically, when in use, the distance between the second clamping head 5 and the first clamping head 4 can be adjusted by the clamping assembly, so that the first clamping head 4 and the second clamping head 5 can interact with each other to clamp and fix the pipe 6. In addition, since the second clamping head 5 is rotatably connected to the clamping assembly, when the forward and reverse motor 3 drives the first clamping head 4 to rotate, the second clamping head 5 can rotate with the rotation of the pipe 6.
[0021] A horizontally arranged displacement component is also installed between the two limit plates 2, and a rust removal component capable of horizontal reciprocating motion between the two limit plates 2 is slidably connected to the displacement component. The rust removal component includes a mounting block 7 arranged in an annular shape, the mounting block 7 is coaxially arranged with the first abutting head 4, and the mounting block 7 is connected to the displacement component. The mounting block 7 is also threadedly connected with three first adjusting screws 8 distributed at equal intervals along the circumference of the mounting block 7, each of the first adjusting screws 8 is parallel to the radial direction of the mounting block 7 and passes through the side wall of the mounting block 7, one of the first adjusting screws 8 is located at the top of the mounting block 7, and the other two first adjusting screws 8 are located at one end of the mounting block 7 and are both installed with a rust removal plate 11. Before using the utility model, it is necessary to adjust the position of the rust removal plate 11 according to the outer diameter of the pipe 6. Specifically, the position of the rust removal plate 11 can be adjusted by rotating the first adjusting screw 8 located on both sides of the lower part of the mounting block 7 until the pipe 6 is inserted into the mounting block 7 and placed horizontally on the two rust removal plates 11, and the two ends of the pipe 6 can be aligned with the first tightening head 4 and the second tightening head 5 at the same time. For example, the distance from the two rust removal plates 11 to the center of the mounting block 7 can be adjusted to be equal to half of the outer diameter of the pipe 6. At this time, the pipe 6 is inserted into the mounting block 7 and placed horizontally on the two rust removal plates 11, and the two ends of the pipe 6 can be aligned with the first tightening head 4 and the second tightening head 5 at the same time.
[0022] When the utility model is in use, firstly start the displacement component to move the rust removal component to the position of the second tightening head 5, then insert one end of the pipe 6 into the mounting block 7 and place it horizontally on the rust removal plate 11. Since the position of the rust removal plate 11 has been adjusted in place, the pipe 6 in a horizontal state will automatically align with the first tightening head 4 and the second tightening head 5, thereby saving the time for workers to align the pipe 6 with the first tightening head 4 and the second tightening head 5, thereby improving work efficiency. Then, the first adjusting screw 8 located at the top of the mounting block 7 is pressed against the pipe 6, and then the displacement component is started, so that the pipe 6 can be driven to press against the first tightening head 4, so that the rust removal component and The first clamping head 4 can cooperate with each other to support and fix the pipe 6, and the pipe 6 is also in a state of being aligned with the second clamping head 5. Then, the horizontal position of the second clamping head 5 is adjusted by the clamping assembly until the second clamping head 5 is clamped against the pipe 6, and the first adjusting screw 8 located at the top position of the mounting block 7 is moved away from the pipe 6. Finally, the forward and reverse motor 3 is started to drive the pipe 6 to rotate, and the displacement assembly is started at the same time to drive the rust removal plate 11 to reciprocate along the axial direction of the pipe 6. At this time, the rust removal plate 11 is in contact with the outer wall of the pipe 6, and the rust removal plate 11 can grind and remove rust on the outer wall of the pipe 6. Therefore, the position of the rust removal plate 11 does not need to be adjusted before grinding and rust removal in the utility model.
[0023] When rust removal is completed, the first adjusting screw 8 located at the top of the mounting block 7 is pressed against the pipe 6, and then the second pressing head 5 is moved away from the pipe 6, and the displacement component is started to drive the pipe 6 away from the first pressing head 4, and finally the first adjusting screw 8 at the top of the mounting block 7 is moved away from the pipe 6, so that the pipe 6 can be removed. Therefore, the utility model does not need to adjust the position of the rust removal plate 11 before removing the pipe 6; in this way, the utility model does not need to adjust the position of the rust removal plate 11 before each grinding and rust removal and before removing the pipe 6, and it is also convenient to align the pipe 6 with the first pressing head 4 and the second pressing head 5 at the same time, thereby improving work efficiency.
