[0030] 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.

[0031] Please see Figure 1-6 This utility model provides a new technical solution: a CNC cutting tool for machine tool processing, including a machine tool 1, a rectangular mounting plate 9 fixedly connected to the cutting tool drive end of the machine tool 1, a mounting assembly, the mounting assembly being set on the machine tool 1 and the rectangular mounting plate 9, the machine tool 1 including a mounting frame 3, the mounting frame 3 being fixedly connected to the left side of the machine tool 1, and a dual-axis cylinder mounting box 4 being fixedly connected to the left side of the mounting frame 3;

[0032] The dual-axis cylinder is fixedly installed inside the dual-axis cylinder mounting box 4. The upper and lower extension ends of the dual-axis cylinder slide through the outer surface of the dual-axis cylinder mounting box 4. The upper and lower extension ends of the dual-axis cylinder are fixedly connected to the connecting plate 6.

[0033] Among them, the two connecting plates 6 are fixedly connected to the opposite sides of the fixing rod 16, and the left side of the dual-shaft cylinder mounting box 4 is fixedly connected to the rectangular block 18.

[0034] The rectangular block 18 has a mounting groove 17 on its front surface, and a mounting plate 5 is slidably connected to the inner wall of the mounting groove 17.

[0035] Furthermore, fixing holes 10 are provided on both the upper and lower surfaces of the mounting plate 5, and the opposing surfaces of the two fixing rods 16 slide through into the interior of the corresponding fixing holes 10.

[0036] Among them, a circular tube 2 is fixedly connected to the left side of the mounting plate 5, and through holes 11 communicating with the interior of the circular tube 2 are opened on both the upper and lower surfaces.

[0037] Furthermore, a sliding sleeve 15 is slidably connected to the inner wall of the circular tube 2, and a spring 14 is fixedly connected to the lower surface of the sliding sleeve 15. The lower end of the spring 14 is fixedly connected to the bottom of the circular tube 2.

[0038] Furthermore, a bearing 19 is fixedly sleeved on the inner wall of the sliding sleeve 15, and a cutting tool 7 is fixedly sleeved on the inner wall of the bearing 19. The upper and lower ends of the cutting tool 7 respectively penetrate through the inner wall of the corresponding through hole 11.

[0039] Furthermore, a circular block 13 is fixedly connected to the upper end of the cutting tool 7, and a rectangular mounting groove 12 is provided on the circular block 13.

[0040] Furthermore, the mounting assembly also includes an L-shaped connecting plate 8, which is fixedly connected to the rear side of the lower surface of the rectangular mounting plate 9.

[0041] Furthermore, the front end of the L-shaped connecting plate 8 extends through the inner wall of the rectangular mounting groove 12.

[0042] Furthermore, when using this machine tool to process CNC cutting tools, when it is necessary to replace the cutting tool 7, firstly, start the two dual-axis cylinders. The up and down extension and retraction of the two dual-axis cylinders will drive the two connecting plates 6 to move to opposite positions, thereby driving the two fixed rods 16 to disengage from the inner walls of the two fixed holes 10.

[0043] Then, you can hold the circular tube 2 and push the circular tube 2 forward to move it forward as a whole, thereby separating the rectangular mounting groove 12 from the L-shaped connecting plate 8, and at the same time separating the mounting plate 5 from the inner wall of the mounting groove 17, thus completing the disassembly of the cutting blade 7.

[0044] When a new cutting tool 7 needs to be installed, first pick up the new cutting tool 7, place the mounting plate 5 on the inner wall of the mounting groove 17, and at the same time make the front end of the L-shaped connecting plate 8 pass through the inner wall of the rectangular mounting groove 12. Then start the dual-axis cylinder, and the upper and lower extension ends of the dual-axis cylinder move inward synchronously, driving the two connecting plates 6 to move to the opposite position, so that the two fixing rods 16 are respectively inserted into the fixing holes 10 on the upper and lower surfaces of the mounting plate 5, forming a rigid locking structure with upper and lower symmetry.

[0045] When the sliding sleeve 15 slides on the inner wall of the circular tube 2, the spring 14 below it provides a certain preload, so that the cutting tool 7 has a certain buffering capacity in the axial direction: when the cutting tool 7 contacts the workpiece and generates axial impact force, the spring 14 is compressed to absorb vibration energy, avoiding tool breakage or machine tool vibration caused by rigid collision.

[0046] When the machine tool drives the rectangular mounting plate 9 to rotate, the cutting tool 7 rotates synchronously with the sliding sleeve 15 through the bearing 19. The preload of the spring 14 keeps the sliding sleeve 15 in contact with the inner wall of the circular tube 2, reducing rotational eccentricity.

[0047] By setting up the installation component, when disassembling and installing the cutting tool 7, only the two-way cylinder needs to be activated, eliminating the need for using professional tools to disassemble and install the cutting tool 7, thereby improving the efficiency of installing and disassembling the cutting tool 7.

[0048] Structural Description:

[0049] Mounting bracket 3:

[0050] Fixed to the left side of the machine tool 1, the dual-axis cylinder mounting box 4 supports the installation stability of the dual-axis cylinder and transmits the driving force of the cylinder to the mounting plate 5. It is a key support structure connecting the machine tool body and the tool mounting assembly.

[0051] Twin-shaft cylinder mounting box 4:

[0052] Fixed to the left side of the mounting bracket 3, the dual-axis cylinder is installed inside, and the outer surface is connected to the rectangular block 18, which provides installation space and protection for the dual-axis cylinder, ensuring the smoothness and sealing of the cylinder piston movement.

[0053] Mounting plate 5:

The left side is connected to the circular tube 2, and the fixing rod 16 driven by the dual-axis cylinder is locked or released to realize the quick installation and removal of the cutting tool 7.

[0055] Connector plate 6:

[0056] It is fixedly connected to the upper and lower telescopic ends of the dual-shaft cylinder, and the opposite side is connected to the fixing rod 16. As the cylinder piston moves, the fixing rod 16 is driven to insert into or disengage from the fixing hole 10 of the mounting plate 5. It is the intermediate component for power transmission of the dual-shaft cylinder.

[0057] Cutting tool 7:

[0058] The core component of the cutting tool has through holes 11 in a circular tube 2 at both the upper and lower ends. The upper end is connected to a circular block 13, and the lower end is fixed to a sliding sleeve 15 via a bearing 19. It is responsible for cutting the workpiece.

[0074] Both ends are fixed to the connecting plate 6, and the middle is inserted into the fixing hole 10 of the mounting plate 5. The upper and lower symmetrical locking is achieved by the dual-axis cylinder drive. The material is a high-strength alloy, and the surface is hardened to withstand the radial load during cutting.

[0075] Mounting slot 17:

[0076] The inner wall of the rod 16 is slidably fitted to the mounting plate 5 on the front surface of the rectangular block 18, providing lateral positioning for the mounting plate 5 and ensuring accurate alignment between the fixing rod 16 and the fixing hole 10, which facilitates quick locking of the dual-axis cylinder.

[0077] Rectangular block 18:

[0078] Fixed on the left side of the dual-axis cylinder mounting box 4, the front surface has a mounting groove 17 to provide a mounting guide for the mounting plate 5.
