[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] Please refer to Figures 1-3 , this embodiment provides a technical solution: a multi-axis hole processing extrusion tap that is convenient for disassembly and assembly, including a shank 1 and a thread part 2. The shank 1 and the thread part 2 are of an integral structure. The shank 1 includes: a metal rod 3, a transmission rod 4, and a connector 5. One end of the metal rod 3 is fixed to the thread part 2, and the other end is provided with a mounting hole 17. At least one plane is provided on the side of the mounting hole 17. The transmission rod 4 is matched with the mounting hole 17, and one end of the transmission rod 4 is inserted into the mounting hole 17. The end of the transmission rod 4 located outside the mounting hole 17 is fixed to the connector 5. The connector 5 is used to fix the transmission rod 4 to the multi-axis hole machine head. The connector 5 is an existing standard part. During operation, the standard part can be connected to the multi-axis hole machine head. The multi-axis hole machine head drives the rotation of the connector 5 and drives the rotation of the thread part 2 through the transmission rod 4, so that the thread part 2 can process the workpiece.

[0026] It also includes a magnetic part 6. The magnetic part 6 is used to adsorb the metal rod 3 on the transmission rod 4. When the thread part 2 needs to be replaced due to damage or other reasons during the processing, the magnetic part 6 can be used to quickly separate and fix the metal rod 3 and the transmission rod 4 respectively, which facilitates the disassembly and assembly of the extrusion tap during multi-axis hole processing and improves the processing efficiency.

[0027] As a preferred implementation mode, the transmission rod 4 is of a cylindrical structure, and anti-slip teeth 7 are arranged in a ring on its side. The mounting hole 17 is provided with a tooth groove 8 that matches the anti-slip teeth 7. The anti-slip teeth 7 are inserted into the tooth groove 8. During the processing, through the cooperation of the anti-slip teeth 7 and the tooth groove 8, the sliding of the transmission rod 4 relative to the metal rod 3 is largely avoided, especially during the long-term mechanical wear process, and the anti-wear ability of the transmission rod 4 is improved.

[0028] Example 2

[0029] Please refer to Figures 4-6 , the difference between this embodiment and the first embodiment is that this embodiment discloses a magnetic part 6, the magnetic part 6 includes a first magnet 9 and a second magnet 10, the first magnet 9 and the second magnet 10 are respectively fixed at the bottom of the mounting hole 17 and the bottom of the transmission rod 4, and the relative fixation of the transmission rod 4 and the metal rod 3 is realized through the adsorption of the first magnet 9 and the second magnet 10. When replacing the tap, the thread part 2 can be pulled off with force.

[0030] In order to prevent the first magnet 9 from being damaged due to the extrusion force of the tap during the tap extrusion operation, a first groove 11 is provided at the bottom of the mounting hole 17, the opening area of the first groove 11 is smaller than the area of the bottom of the mounting hole 17, and the first magnet 9 is fixed in the first groove 11. In this way, the extrusion force of the transmission rod 4 can directly act on the metal rod 3.

[0031] In order to prevent the second magnet 10 from being damaged due to the extrusion force of the tap during the tap extrusion operation, a second groove 12 is provided at the bottom of the transmission rod 4, and the second magnet 10 is fixed in the second groove 12.

[0032] Example 3

[0033] Please refer to Figure 4 and Figure 6 , the difference between this embodiment and the second embodiment is that the magnetic part 6 disclosed in this embodiment further includes a first screw 13 and a second screw 14. A first threaded hole 18 is provided at the bottom of the first groove 11, a first through hole 15 is provided at the position of the first magnet 9 corresponding to the first threaded hole 18, one end of the first screw 13 passes through the first through hole 15 and is threadedly connected to the first threaded hole 18, a second threaded hole is provided at the bottom of the second groove 12, a second through hole is provided at the position of the second magnet 10 corresponding to the second threaded hole, and one end of the second screw 14 passes through the second through hole and is threadedly connected to the second threaded hole.

[0034] The first magnet 9 and the second magnet 10 can be respectively fixed in the first groove 11 and the second groove 12 through the first screw 13 and the second screw 14, and it is convenient to disassemble the first magnet 9 and the second magnet 10 when replacing the first magnet 9 and the second magnet 10.

[0035] In order to prevent the first screw 13 and the second screw 14 from being subjected to extrusion force during the working process, third grooves 16 for placing the nuts of the first screw 13 and the second screw 14 are respectively provided on the first magnet 9 and the second magnet 10.

[0036] Example 4

[0037] Please refer to Figure 6 , the difference between this embodiment and the third embodiment is that internal threads are provided on the inner sides of the first through hole 15 and the second through hole, and the first magnet 9 and the second magnet 10 are respectively threadedly connected to the first screw 13 and the second screw 14 through the internal threads.

[0038] When replacing the first magnet 9 and the second magnet 10, due to the long-term pollution of impurities in the environment, it may be difficult for the first magnet 9 and the second magnet 10 to be separated from the first groove 11 and the second groove 12. In this case, the first magnet 9 and the second magnet 10 can be respectively threadedly connected to long screws, and the first magnet 9 and the second magnet 10 can be taken out by pulling the long screws forcefully.
