The same chuck 21 is also provided on the tool holder 3. The chuck 21 is fixedly connected to the tool holder 3, and the chuck 21 is also detachably connected with an adjusting member 211 for adjusting the tightness. In specific implementation, the chuck 21 clamps the titanium tube with multiple transmission-connected claws, and the adjusting member 211 can drive multiple claws to move synchronously in a rotational manner, and the motor 14 controls the rotation of the chuck 21 by setting gears on the motor 14 and the chuck 21, and transmitting the transmission in a meshing manner. In other embodiments, the chuck 21 can also be driven pneumatically to further improve the accuracy of the drive.

[0048] like Figure 1 and Figure 2 As shown, the driving mechanism further includes a guide rod 6, which is arranged along the length direction of the screw rod and is parallel to the screw rod, and the guide rod 6 is slidably connected to the knife seat 3. In specific implementation, the knife seat 3 can move along the guide rod 6, thereby improving the stability of the movement of the knife seat 3.

[0049] like Figure 1 and Figure 2As shown, the workbench 1 is provided with a discharge groove 13 between the guide rails 11. The discharge groove 13 is arranged corresponding to the position of the chuck 21, and the discharge groove 13 is for the titanium tube debris to fall.

[0050] Working principle: When boring a hole, first extend the boring rod 31 into the titanium tube, and then drive the chuck 21. At this time, the titanium tube rotates, and the inner wall of the titanium tube can be processed. During the processing, it is necessary to drive the tool holder 3 to move along the workbench 1, and the boring rod 31 is continuously inserted into the titanium tube, thereby completing the processing of the titanium tube. After the processing is completed, the chuck 21 can remove the titanium tube.

[0051] Embodiment 2

[0052] like Figure 3 As shown, the difference between the second embodiment and the first embodiment is that the guide rod 6 in the second embodiment is rotatably connected with the workbench 1, and an embedding groove 61 is provided on the guide rod 6, and the embedding groove 61 is arranged along the length direction of the guide rod 6, and a transmission gear 611 is embedded in the embedding groove 61 and the transmission gear 611 can rotate with the guide rod 6, and the guide rod 6 can also slide along the embedding groove 61 during the rotation process, and a baffle 33 is arranged in the tool holder 3 corresponding to the transmission gear 611, and the baffle 33 is fixedly connected to the tool holder 3 so as to drive the transmission gear 611 to move with the tool holder 3.

In specific implementation, when the guide rod 6 rotates, the guide rod 6 will drive the transmission gear 611 to rotate, and at this time, the transmission gear 611 will drive the driving rod 32 to drive the tool holder 3 to move along the ball screw 5, thereby completing the movement.

[0053] like Figure 3 As shown, a transmission belt is provided between the guide rod 6 and the motor 14 driving the chuck 21 to rotate, and the transmission belt can drive the guide rod 6 to rotate while driving the chuck 21 to rotate. In specific implementation, when the chuck 21 rotates, the titanium tube rotates accordingly. If the rotation of the titanium tube is not synchronized with the movement of the boring bar 31, it is easy to have a low internal boring quality. Therefore, when the chuck 21 drives the titanium tube to move, the boring bar 31 can move at a synchronous rate, and it is more convenient to adjust the speed of the synchronous operation. The inner wall of the titanium tube at a position can be completely processed before moving the boring bar 31, further improving the boring quality.

[0054] Working principle: The basic working principle is the same as that of the first embodiment, but during the processing, the motor 14 drives the chuck 21 and the guide rod 6 to move at the same time. The chuck 21 rotates and the guide rod 6 rotates. During the rotation of the guide rod 6, the drive rod 32 can be driven to rotate. The drive rod 32 can drive the tool holder 3 to move along the guide rod 6, so that the chuck 21 and the boring bar 31 can move synchronously.
