[0002] Diamond tools possess advantages such as extremely high hardness and wear resistance, low coefficient of friction, high elastic modulus, high thermal conductivity, low coefficient of thermal expansion, and low affinity for non-ferrous metals. They can be used for precision machining of non-metallic hard and brittle materials such as graphite, high wear-resistant materials, composite materials, high-silicon aluminum alloys, and other tough non-ferrous metal materials. There are many types of diamond tools with significant differences in performance. The structure, manufacturing methods, and application fields of different types of diamond tools vary considerably.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figure 1-4 This embodiment of a diamond CNC cutting tool with length adjustment function includes a sleeve 7 and a cutting head 1. An upper mounting block 2 and a lower mounting block 3 are slidably inserted into the sleeve 7. The bottom surface of the upper mounting block 2 abuts against the top surface of the lower mounting block 3. A plurality of upper connecting holes 21 are equally spaced on the right side of the upper mounting block 2. A plurality of lower connecting holes 31 are opened on the right side of the lower mounting block 3 corresponding to the upper connecting holes 21. The front surfaces of the upper mounting block 2 and the lower mounting block 3 both extend to the outside of the sleeve 7. A movable sleeve 4 is slidably connected to the outside of the sleeve 7. A threaded hole is opened laterally on the right side of the movable sleeve 4. A screw 5 is threadedly connected to the threaded hole. A positioning rod 8 is fixed to the left end of the screw 5. A through hole 6 is opened on the right side of the sleeve 7 corresponding to the upper connecting hole 21 and the lower connecting hole 31. The left end of the positioning rod 8 passes through the through hole 6 and extends into the upper connecting hole 21 and the lower connecting hole 31, and is slidably connected to the upper connecting hole 21 and the lower connecting hole 31. The cutting head 1 is detachably connected to the lower mounting block 3.

[0022] In application, the screw 5 is rotated using a hex wrench to move it out of the threaded hole. After the screw 5 moves, the positioning rod 8 also moves and enters the threaded hole. At this time, the positioning rod 8 moves out of the upper connecting hole 21 and the lower connecting hole 31, and then moves into the through hole 6. After the positioning rod 8 separates from the upper connecting hole 21 and the lower connecting hole 31, the upper mounting block 2 and the lower mounting block 3 can also move within the sleeve 7. After the upper mounting block 2 and the lower mounting block 3 move to the appropriate position, the screw 5 can be rotated in the opposite direction to move the positioning rod 8 into the upper connecting hole 21 and the lower connecting hole 31 to position the upper mounting block 2 and the lower mounting block 3. Alternatively, after the upper mounting block 2 and the lower mounting block 3 move, the moving sleeve 4 can be moved synchronously to adapt to different usage requirements. After the position of the upper mounting block 2 and the lower mounting block 3 is adjusted, the length of the tool can be adjusted. Example

[0023] The basic content is from Example 1, the difference being:

[0024] Please see Figure 1-2In this embodiment, both the upper mounting block 2 and the lower mounting block 3 move longitudinally within the sleeve 7. The upper mounting block 2 and the lower mounting block 3 have the same length and width. The movable sleeve 4 moves longitudinally on the sleeve 7.

[0025] In application, after the positioning rod 8 moves and separates from the upper connecting hole 21 and the lower connecting hole 31, the upper mounting block 2 and the lower mounting block 3 can move longitudinally within the sleeve 7, thereby adjusting the length of the tool. At the same time, during the movement of the upper mounting block 2 and the lower mounting block 3, the moving sleeve 4 can also move on the sleeve 7 to fix the upper mounting block 2 and the lower mounting block 3. Example

[0026] The basic content is from Example 1, the difference being:

[0027] Please see Figure 3-4 In this embodiment, the back of the blade 1 is provided with a groove 9. The upper mounting block 2 and the lower mounting block 3 are both inserted into the groove 9. The top surface of the lower mounting block 3 and near its left end are provided with a placement groove 15. Springs 11 are fixed to the left and right side walls of the inner cavity of the placement groove 15. A moving block 10 is fixed to the opposite side of the two springs 11. The back of the moving block 10 is provided with an inclined surface. A rod 12 is fixed to the opposite side of the two moving blocks 10. The end of the rod 12 away from the moving block 10 passes through and... Extending to the outside of the lower mounting block 3, a corresponding insertion hole 14 is provided in the groove 9 for the insertion rod 12. The insertion rod 12 is slidably inserted into the insertion hole 14. A pushing block 13 is fixed on the bottom surface of the upper mounting block 2 corresponding to the moving block 10. The pushing block 13 abuts against the inclined surface of the moving block 10. The upper mounting block 2 and the lower mounting block 3 move longitudinally in the groove 9. The width of the lower mounting block 3 is adapted to the width of the inner cavity of the groove 9. The insertion rod 12 is clearance-fitted with the insertion hole 14. The insertion rod 12 moves laterally in the placement groove 15.

[0028] In application, after the positioning rod 8 moves and separates from the upper connecting hole 21 and the lower connecting hole 31, the upper mounting block 2 can move on the lower mounting block 3 to replace the cutter head 1. After the upper mounting block 2 moves backward, the pushing block 13 will also move synchronously. After the pushing block 13 moves backward, the compressed spring 11 and the moving block 10 will spring back to their original positions, and the insertion rod 12 will move out of the insertion hole 14. At this time, the lower mounting block 3 can be separated from the cutter head 1, and the cutter head 1 can be replaced. In the subsequent installation process of the cutter head 1, after the cutter head 1 is connected to the lower mounting block 3, the upper mounting block 2 is pushed forward to drive the pushing block 13 to move. The pushing block 13 will squeeze the moving block 10, the spring 11 and the insertion rod 12, so that the insertion rod 12 is connected to the insertion hole 14, and the cutter is installed.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
