A through hole for the punch needle to penetrate is arranged along the vertical direction in the guiding part. A second through groove is arranged along the vertical direction at the corresponding end of the guiding part and the metal pipe. A pair of opposed fiber optic components is arranged between the first through groove and the second through groove, and the pair of opposed fiber optic components is used to detect the punching situation of the metal pipe.

[0006] Preferably, the first through groove is arranged along the center of the plug-in end. The second through groove is arranged corresponding to the first through groove, and the inner walls of the first through groove and the second through groove are flush.

[0007] Through the above structure, it is ensured that the first through groove and the second through groove are always parallel to the through hole in the vertical direction, thereby improving the accuracy of the pair of opposed fiber optic components in detecting the punching situation of the metal pipe.

[0008] Preferably, the pair of opposed fiber optic components includes a transmitter arranged at the first through groove and a receiver arranged at the second through groove. The transmitter and the receiver are arranged parallel to the through hole.

[0009] Through the above structure, the transmitter and the receiver can accurately detect the punching along the vertical and horizontal directions of the through hole, thereby providing the detection accuracy.

[0010] Preferably, the corresponding ends of the plug-in end and the metal pipe are chamfered.

[0011] Through the above structure, it is convenient for the installation of the metal pipe and reduces the wear of the inner wall of the metal pipe by the plug-in end of the positioning block.

[0012] A metal pipe punching machine includes a clamping member and a punching mechanism corresponding to the clamping member. The clamping member is provided with a punching detection mechanism as described in any one of the above.

[0013] With the above structure, the punching can be detected during the punching process without the need for additional separate detection, improving the practicability of the metal pipe punching machine.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The structure of the present disclosure is simple. By adding a fiber optic transceiver assembly to detect the punching condition of the metal pipe, qualified metal pipes can be effectively detected, providing great assistance for subsequent processes. At the same time, maintenance, repair, and debugging are all convenient, the use cost is low, and the punching efficiency and qualification rate are greatly improved.
