(e.g., servo motors, etc.) During the knurling operation, the two mounting seats 501 initially remain relatively far apart. After the copper tube moves to the processing position, the two mounting seats 501 move closer to each other, and the two rollers 503 and one knurling wheel 504 move closer to each other to form a pair of adjacent structures. The gap in the middle is the processing position of the copper tube and achieves clamping of the copper tube. During knurling, the seventh drive device 505 drives the knurling wheel 504 to rotate.

During the knurling process, the compression and movement of the concave grooves can create localized annular protrusions on the surface of the copper tube. Simultaneously, the concave grooves correspond to the knurling portion of the knurling wheel 504, allowing the device to perform knurling operations on these protrusions, resulting in a more pronounced knurling effect and facilitating subsequent assembly of the copper tube. Figure 5 As shown, the roller 503 can also be driven to rotate by a corresponding drive mechanism. In order to save drive, the shafts of the two rollers 503 can be connected by gear meshing, so that when driving one roller 503 to rotate, the other roller 503 can be driven to deflect at the same time.

[0039] This utility model provides a copper tube knurling machine, such asFigure 6 As shown, a positioning mode for positioning the copper pipe before and after processing is specifically provided, and specifically, the device further includes a positioning mechanism 7, the positioning mechanism 7 includes an eighth driving device 701 and a positioning rod 702 arranged at the output end of the eighth driving device 701, wherein the positioning rod 702 can abut the end face position of the copper pipe before and after processing, and the eighth driving device 701 can be an electric cylinder, which can abut from the other side when the core mold 402 pushes the copper pipe, so as to prevent the copper pipe from deviating too much and thus position the copper pipe, thereby ensuring the knurling position accuracy.

[0040] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and deformations can be made, and these improvements and deformations should be considered as the protection scope of the present application.
