[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 6 As shown, the utility model provides a drilling tool for a CNC machining center that is easy to clean, including a connecting member 1 and an insert block 5. The bottom of the connecting member 1 is fixedly connected to a mounting frame 3. A slot 14 is provided on one side of the inner wall of the mounting frame 3. A hand-tightening bolt 2 is threadedly connected through the inner wall of one side of the slot 14. A push block 13 is fixedly connected to the rear end surface of the hand-tightening bolt 2. A mounting slot 9 is provided on the front surface of the insert block 5. A first telescopic rod 11 is fixedly connected to the inner bottom of the mounting slot 9. A first spring 10 is sleeved on the outer surface of the first telescopic rod 11. The front end surface of the retracted rod 11 is fixedly connected with a clamping block 6, the inner surface of the mounting frame 3 and the outer surface of the plug-in block 5 are slidably arranged, the outer surface of the clamping block 6 and the inner surface of the card slot 14 are snap-fitted, the cross-section of the clamping block 6 is inclined, positioning grooves 8 are provided on the inner walls on both sides of the mounting frame 3, and the outer surfaces of the two positioning blocks 7 are fixedly connected with the outer surfaces of the two positioning blocks 7, and the outer surfaces of the two positioning blocks 7 are respectively slidably arranged with the inner surfaces of the two positioning grooves 8, the bottom of the plug-in block 5 is fixedly connected with a cutter head 4, and the outer surface of the clamping block 6 and the inner surface of the mounting slot 9 are slidably arranged.

[0025] The effect achieved by the entire embodiment 1 is that when the cutter head 4 needs to be cleaned, the staff rotates the hand-tightening bolt 2 to rotate the hand-tightening bolt 2 on the mounting frame 3, so that the push block 13 moves to the rear side, thereby moving the clamping block 6 to the mounting groove 9 through the push block 13, so that the clamping block 6 and the clamping groove 14 are no longer engaged, and then the staff can take out the plug block 5 from the mounting frame 3 and disassemble the cutter head 4, so as to facilitate comprehensive cleaning and lubrication of the cutter head, and extend the life and stability of the cutter head 4. When the cleaning is completed, the hand-tightening bolt 2 is rotated to reset the push block 13, and then the positioning block 7 is aligned with the positioning groove. 8 is aligned, and then the plug block 5 is inserted into the interior of the installation frame 3. When the plug block 5 is inserted, the cross section of the card block 6 will be squeezed by the installation frame 3, so that the card block 6 moves to the installation slot 9 and compresses the first spring 10 and the first telescopic rod 11. Therefore, when the plug block 5 is fully inserted into the installation frame 3, the installation slot 9 is aligned with the card slot 14. At this time, the card block 6 is no longer squeezed. At this time, the card block 6 is pushed outward by the restoring force of the first spring 10 during rebound, and the moving direction of the card block 6 is limited by the first telescopic rod 11, so that the card block 6 is engaged with the card slot 14, and the installation of the cutter head 4 is completed.

[0026] Embodiment 2, as Figure 1-Figure 6 As shown, a receiving groove 15 is provided at the inner top of the installation frame 3, a second telescopic rod 17 is fixedly connected to the inner bottom of the receiving groove 15, a second spring 18 is sleeved on the outer surface of the second telescopic rod 17, and a stopper 16 is fixedly connected to the bottom of the second telescopic rod 17.

[0027] The effect achieved by the entire embodiment 2 is that when the plug block 5 is fully inserted into the mounting frame 3, the plug block 5 will push the block 16 upward and compress the second spring 18 and the second telescopic rod 17, so that when the plug block 5 is no longer limited, the block 16 is pushed outward by the restoring force of the second spring 18 when it rebounds, and the moving direction is limited by the second telescopic rod 17, so that the block 16 can push the plug block 5 away from the mounting frame 3 for a certain distance, thereby assisting the disassembly of the cutter head 4.

[0028] Working principle: when the cutter head 4 needs to be cleaned, the staff rotates the hand-tightening bolt 2 to rotate the hand-tightening bolt 2 on the mounting frame 3, so that the push block 13 moves backward, thereby moving the card block 6 into the mounting slot 9 through the push block 13, so that the card block 6 and the card slot 14 are no longer engaged, and the stopper 16 is pushed outward by the restoring force of the second spring 18 when it rebounds, and the moving direction is limited by the second telescopic rod 17, so that the block 5 is pushed a certain distance from the mounting frame 3 through the block 16, and then the staff can take the block 5 out of the mounting frame 3 and disassemble the cutter head 4, so as to facilitate comprehensive cleaning and lubrication of the cutter head 4, and extend the life and stability of the cutter head 4. After completion, turn the hand-tightening bolt 2 to reset the push block 13, then align the positioning block 7 with the positioning slot 8, and then insert the plug block 5 into the interior of the mounting frame 3. When the plug block 5 is inserted, the cross-section of the card block 6 will be squeezed by the mounting frame 3, causing the card block 6 to move into the mounting slot 9 and compress the first spring 10 and the first telescopic rod 11. Therefore, when the plug block 5 is fully inserted into the mounting frame 3, the mounting slot 9 is aligned with the card slot 14. At this time, the card block 6 is no longer squeezed. At this time, the restoring force of the first spring 10 during rebound pushes the card block 6 outward, and the moving direction of the card block 6 is limited by the first telescopic rod 11, so that the card block 6 is engaged with the card slot 14, and the installation of the cutter head 4 is completed.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
