[0027] The cleaning assembly 5 comprises a limiting frame 501, the top of the limiting frame 501 is fixedly connected with the telescopic end of the electric push rod 4, the inside of the limiting frame 501 is slidably connected with a moving plate 502, the bottom of the moving plate 502 is provided with a brush plate 503, the left side of the top of the moving plate 502 is rotatably connected with a rotating rod 504, the left side of the top of the limiting frame 501 is fixedly connected with an L-shaped frame 505, the bottom of the L-shaped frame 505 is fixedly connected with a micro motor 506, the output end of the micro motor 506 is fixedly connected with a disc 507, and one side of the disc 507 close to the rotating rod 504 is rotatably connected with the rotating rod 504.

[0028] In the embodiment, by arranging the cleaning assembly 5, when the micro motor 506 is started, the disc 507 is driven to make a circular motion, and then the circular motion of the disc 507 is converted into the reciprocating linear motion of the moving plate 502 in the limiting frame 501. With the reciprocating linear motion of the moving plate 502, the brush plate 503 can brush back and forth on the surface of the metal pipe in the same motion mode. During the brushing process, the bristles on the brush plate 503 rub against rust, dust and other impurities on the surface of the pipe. Since the bristles have a certain elasticity and friction, when the bristles come into contact with the impurities, the rust particles and dust can be detached from the surface of the metal pipe, thereby achieving the purpose of cleaning the surface of the welded part of the metal pipe.

[0036] Specifically, as shown in Figure 5 The bottom of the moving plate 502 is provided with a clamping groove 12, and the top of the brush plate 503 is fixedly connected with a clamping block 13.

[0037] Specifically, as shown in Figure 5 The inside of the moving plate 502 is threadedly connected with a fastening screw 14, and the inside of the clamping block 13 is provided with a threaded groove 15 matched with the fastening screw 14.

[0038] In the embodiment, the card block 13 and the card slot 12 are arranged to accurately position the brush plate 503 at the bottom of the moving plate 502, so that the brush plate 503 can move with the moving plate 502 during the operation, thereby achieving stable and effective cleaning effect; the fastening screw 14 and the threaded groove 15 are arranged, and the fastening and loosening operation of the connection can be realized by rotating the fastening screw 14, which is convenient for subsequent installation and disassembly of the operator.
