[0031] The rotating circle 2 is fixedly mounted on the inner side surface of the driven gear 43, and a rotating cutter disc 21 is fixedly mounted on one end of the rotating circle 2. A plurality of mounting seats 3 are provided on the front side of the rotating cutter disc 21, and a mounting block 31 is fixedly mounted on the inner side surfaces of the plurality of mounting seats 3. A tool 32 is provided inside the mounting block 31.

[0032] The driving gear 42 and the driven gear 43 are both disposed on the inner side of the installation cavity 11 .

[0034] When the cutter 32 is in use, it can slide on the inner side of the mounting block 31, and after moving to a suitable position, it can be threadedly connected to the inside of the mounting block 31 by a limit screw, and then one end of the limit screw is pressed against the cutter 32 to limit the position of the cutter 32;

[0036] The output end of the motor 41 is connected to the input end of the reducer 4, and the output end of the reducer 4 is connected to the driving gear 42. This can reduce the rotation speed of the rotary cutter 21, thereby increasing the stability of the knurling process.

[0037] When in use, the mounting base 3 can be removed from the top of the rotating cutter disc 3, so that the staff can replace the cutter 32 according to different knurling patterns.

[0038] When in use, the pressure bearing 51 is installed through the fixed ring 5, and then the rotating ring 2 is installed on the inner side of the pressure bearing 51. This can support the rotating ring 2 and increase the stability of the rotating ring 2 when rotating.

[0039] The working principle of a pipeline knurling machine provided by the utility model is as follows:

[0040] When in use, the user moves the tool 32 so that the tool 32 slides inside the mounting block 31, so that one end of the tool 32 abuts against the side of the pipeline, and then limits the tool 32. After that, the user starts the motor 41, so that the motor 41 drives the reducer 4 to rotate, so that the reducer 4 drives the driving gear 42 to rotate, and then the driving gear 42 drives the rotating circle 2 to rotate, and then the rotating circle 2 drives the rotating cutter disc 21 to rotate on the outer side of the pipeline, and then drives the tool 32 to rotate on the outer side of the pipeline through the mounting seat 3 and the mounting block 31, thereby knurling the outer side of the pipeline.

[0041] Compared with the related art, the pipeline knurling machine provided by the utility model has the following beneficial effects:
