[0034] Please refer to Figures 1 to 4 , in order to further ensure the machining accuracy of the device and improve the machining efficiency, the clamping mechanism 5 in this embodiment includes two groups of guide rods 507 fixed to the inner cavity of the connecting plate 4, a starting component, and a clamping component. The starting component includes a driving motor 501 fixed to the middle of the inner top wall of the connecting plate 4, a driving rod 502, an adjusting gear 503, two adjusting racks 504, two adjusting rods 505, and two support rods 506. The output shaft of the driving motor 501 is fixed to the driving rod 502. The outer surface of the driving rod 502 is fixed to the inner wall of the axis center of the adjusting gear 503. The adjusting gear 503 is meshed with the adjusting rack 504. One side of the two adjusting racks 504 is respectively hinged to the opposite side of the two adjusting rods 505. The adjusting rods 505 are slidably connected to the outer surface of the support rods 506. By driving the driving rod 502 and the adjusting gear 503 to rotate through the driving motor 501, the adjusting gear 503 drives the adjusting rack 504 and the adjusting rod 505 to move, so as to realize the clamping action of the clamping component.

[0035] Among them, four connecting seats are fixed on the inner bottom wall of the connecting plate 4. The opposite sides of the left and right connecting seats are respectively fixed to the opposite sides of the two guide rods 507. The connecting seats are used to fix the guide rods 507 to ensure the stability of the guide rods 507. The bottom end of the driving rod 502 is rotatably connected to the inner bottom wall of the connecting plate 4 through a bearing, enabling the driving rod 502 to rotate stably.

[0036] Meanwhile, the clamping assembly includes two moving plates 508, two groups of guide sliders 509, and multiple groups of clamping rods 510. The opposite sides of the front and rear guide sliders 509 are respectively fixed to the front and rear sides of the moving plate 508. The top of the clamping rod 510 is fixed to the lower surface of the moving plate 508. Two guide chutes 511 are provided on both the front and rear sides of the inner cavity of the connecting plate 4. The guide chutes 511 are slidably connected to the guide sliders 509. The movement of the moving plate 508 drives the clamping rods 510 to perform clamping actions to adapt to drill bits of different sizes and specifications.

[0037] In addition, two moving holes are provided on the moving plate 508. The moving holes are slidably connected to the guide rods 507.

The adjusting holes are slidably connected to the clamping rods 510, enabling the moving plates 508 to move smoothly in the inner cavity of the connecting plate 4.

[0038] All the electrical components mentioned in the text are electrically connected to the controller and the power supply. The control mode of the present utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. Moreover, the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0039] The working principle of the above embodiment is as follows:

[0040] After the drill bit to be processed is placed below the connecting plate 4, by starting the driving motor 501, the output shaft of the driving motor 501 drives the driving rod 502 to rotate. The driving rod 502 drives the adjusting gear 503 to rotate. The adjusting gear 503 meshes with the adjusting tooth plate 504. Due to the rotation of the adjusting gear 503, the adjusting tooth plate 504 moves horizontally in the inner cavity of the connecting plate 4. The adjusting tooth plate 504 slides on the outer surface of the support rod 506 to drive the adjusting rod 505 to move. Since the adjusting rod 505 is hinged to the moving plate 508, the moving plate 508 moves horizontally in the inner cavity of the connecting plate 4. The movement of the moving plate 508 drives the clamping rod 510 to slide in the adjusting hole. Since the top of the clamping rod 510 is fixed to the lower surface of the moving plate 508, the clamping rod 510 can clamp the drill bit to be processed. Then, by moving the adjusting mechanism 2, the position of the connecting plate 4 can be adjusted, and thus the five-axis machining of the drill bit can be realized. The clamping mechanism 5 can adapt to the fixation of drill bits of different specifications and shapes, can stably clamp the drill bit to be processed, and avoid shaking and deviation during the machining process, further improving the machining accuracy. In addition, the moving adjusting mechanism 2 can flexibly adjust the position of the connecting plate 4 through the control and cooperation adjustment of three linear axes of X, Y, and Z and two rotating axes of A and C, realizing the all-round and high-precision machining of the drill bit.
