[0002] CNC cutting tools are a general term for various cutting tools used with CNC machine tools. They are widely used in the automotive, aerospace, and large turbine, steam turbine, generator, and diesel engine manufacturers. These industries place stringent demands on tool efficiency and service life, and utilize assembly line operations or high-precision machining methods.

[0003] Combination fixtures for CNC tools are important tools for clamping and positioning tools in CNC machining. Their selection and use have a significant impact on machining accuracy, efficiency, and safety. When using a general combination fixture for CNC tools, the CNC tool is first placed between two clamping plates, and then the two clamping plates are moved to the side of the tool to fix the tool. However, this type of fixture cannot fix multiple tools, resulting in low clamping efficiency, so it needs to be modified and optimized. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 8 As shown, the utility model provides a multifunctional combined fixture for numerical control tools, comprising a base plate 1 and a connecting frame 3, wherein the connecting frame 3 is fixedly arranged above the base plate 1;

[0026] Two clamping blocks 7 are movably installed at the bottom of the inner side of the connecting frame 3, and a fixing frame 9 is fixedly installed on the side of the connecting frame 3. A handle 10 is rotatably installed on one side of the fixing frame 9, and a threaded rod 11 is fixedly installed on one side of the handle 10. The threaded rod 11 passes through the left and right sides of the fixing frame 9 and extends to the inside of the connecting frame 3. A threaded block 12 is threadedly sleeved on the outer surface of the threaded rod 11, and a push plate 13 is fixedly installed on one side of the threaded block 12. A slider 15 is fixedly installed on one end of the push plate 13, and a slide rod 14 is fixedly installed on the inner side of the connecting frame 3, and the slide rod 14 is movably sleeved with the slider 15.

[0027] When the staff uses it, they first move the clamping block 7 backward to compress a spring 6, then place the tool between the two clamping blocks 7, and then release the clamping block 7. The tool is clamped by the spring 6 and the clamping block 7. Then, the staff rotates the handle 10 to drive the rotation of the threaded rod 11. When the threaded rod 11 rotates, it drives the movement of the threaded block 12. When the threaded block 12 moves, it drives the movement of the push plate 13. When the side of the push plate 13 contacts the side of the clamping block 7, the rotation of the handle 10 can be stopped.

[0028] By moving the clamping block 7 backward to compress the spring 6, the tool is placed between the two clamping blocks 7, and then the clamping block 7 is released to clamp the tool, and then the handle 10 is turned to rotate the threaded rod 11, and then the threaded block 12 and the push plate 13 are moved until the side of the push plate 13 contacts the side of the clamping block 7 and the handle 10 is stopped. Compared with the traditional device, this device clamps the tool through the cooperation of the threaded rod 11 and the push plate 13, so that different tools can be clamped, realizing the function of multi-functional clamping, thereby improving the working efficiency of the device.

[0029] Among them, a groove 2 16 is opened above the connecting frame 3, and a limiting cylinder 17 is fixedly installed on the side of the connecting frame 3. A spring 2 18 is fixedly installed on one side of the limiting cylinder 17. One end of the spring 2 18 extends to the inside of the groove 2 16 and is fixedly installed with a clamping block 19. A handle 20 is fixedly installed on one side of the clamping block 19. One end of the handle 20 extends to the outside of the limiting cylinder 17, and a clamping block 21 is movably installed inside the groove 2 16.

[0030] When the staff uses it, they first place the chip guard plate 22 above the connecting frame 3 and align the block 21 with the inside of the groove 2 16, and then press the chip guard plate 22 downward. When the chip guard plate 22 moves downward, it will drive the block 21 to move downward. When the block 21 moves downward, it will cause the block 19 to move backward, thereby causing the handle 20 to move backward. When the handle 20 moves backward, the spring 2 18 will be compressed. When the bottom of the block 21 contacts the bottom of the groove 2 16, the spring 2 18 will drive the block 19 to move forward, thereby fixing the block 21.

[0031] By placing the chip guard plate 22 on the connecting frame 3, aligning the block 21 with the groove 2 16, and then pressing the chip guard plate 22 downward to drive the block 21 to move, the block 19 and the handle 2 20 move backward, thereby compressing the spring 2 18. When the bottom of the block 21 contacts the bottom of the groove 2 16, the spring 2 18 will drive the block 19 to move forward to fix the block 21. Compared with the traditional device, this device can improve the efficiency of fixing the chip guard plate 22 by fixing the chip guard plate 22, and at the same time can make the chip guard plate 22 faster to install, thereby improving the working efficiency of the device.

[0032] Among them, a groove 4 is opened above the connecting frame 3, a spring 6 is fixedly installed on one side inside the groove 4, a connecting block 5 is fixedly installed on one end of the spring 6, and the top of the connecting block 5 is fixedly connected to the bottom of the clamping block 7.

[0033] By pulling one clamping block 7 backward and placing the tool between the two clamping blocks 7, the tool is fixed by the cooperation of the two clamping blocks 7 and the two springs 6.

[0034] A buffer pad 8 is fixedly mounted on one side of the clamping block 7 , and a side surface of the clamping block 7 is movably connected to the push plate 13 .

[0035] Through the design of the buffer pad 8, when the tool is taken out, the two springs 1 6 drive the clamping block 7 to move toward the middle, reducing the damage caused by the collision between the two clamping blocks 7.

[0036] There are five threaded holes 2 on the top of the bottom plate 1 .

[0037] Through the design of the five threaded holes 2 , the device can be fixed by passing bolts through the interior of the threaded holes 2 .

[0038] Among them, a chip prevention plate 22 is movably installed above the connecting frame 3, and the bottom of the chip prevention plate 22 is fixedly connected to the second clamping block 21.

[0039] The design of the chip guard plate 22 can reduce the amount of debris generated by the cutting tool entering the interior of the device, thereby preventing difficulty in cleaning.

[0040] The working principle and use process of this utility model:

[0041] When the staff uses it, they first move the clamping block 7 backward to compress a spring 6, then place the tool between the two clamping blocks 7, and then release the clamping block 7. The tool is clamped by the spring 6 and the clamping block 7. Then, the staff rotates the handle 10 to drive the rotation of the threaded rod 11. When the threaded rod 11 rotates, it drives the movement of the threaded block 12. When the threaded block 12 moves, it drives the movement of the push plate 13. When the side of the push plate 13 contacts the side of the clamping block 7, the rotation of the handle 10 can be stopped.

[0042] When the staff uses it, they first place the chip guard plate 22 above the connecting frame 3 and align the block 21 with the inside of the groove 2 16, and then press the chip guard plate 22 downward. When the chip guard plate 22 moves downward, it will drive the block 21 to move downward. When the block 21 moves downward, it will cause the block 19 to move backward, thereby causing the handle 20 to move backward. When the handle 20 moves backward, the spring 2 18 will be compressed. When the bottom of the block 21 contacts the bottom of the groove 2 16, the spring 2 18 will drive the block 19 to move forward, thereby fixing the block 21.
