[0002] A CNC machining center is a high-efficiency automated machine tool composed of mechanical equipment and a CNC system, suitable for machining complex parts. A CNC machining center is a CNC machine tool with a tool magazine that can automatically change tools and can perform a variety of machining operations on the workpiece within a certain range.

[0003] According to CN219189510U, a tool blowing device for a CNC machining center includes a fixed frame; a ring-shaped tool holder rotatably mounted on one side of the fixed frame for clamping and rotating the tool; and a connecting valve slidably mounted on the side of the fixed frame away from the ring-shaped tool holder. One end of the connecting valve has an air source interface, and the other end is connected to an air outlet pipe for blowing away debris adhering to the tool around the ring-shaped tool holder. This application has the effect of reducing tool surface corrosion and extending tool life.

[0004] The above-mentioned device blows away the debris attached to the tool on the periphery of the ring tool holder through the air outlet pipe, which has the effect of reducing the corrosion of the tool surface and extending the service life of the tool. According to the instruction manual and the attached drawings, the connecting valve slides through the limiting groove. However, since the debris blown off by the air outlet pipe falls into the limiting groove, it affects the sliding of the connecting valve. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the above-mentioned device blows away the debris attached to the tool on the periphery of the ring tool holder through the air outlet pipe, which has the effect of reducing the corrosion of the tool surface and extending the service life of the tool. According to the specification and the attached drawings, the connecting valve is slidable through the limiting groove. However, the debris blown off by the air outlet pipe falls into the limiting groove, thus affecting the sliding of the connecting valve. Therefore, this utility model provides a tool blowing device for CNC machining centers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tool blowing device for a CNC machining center, comprising a fixed frame, a tool holder top plate at the bottom of the fixed frame, and a tool holder bottom plate at the bottom of the tool holder top plate. A tool head is provided at one end of the tool holder bottom plate. A limiting groove is provided at one end of the fixed frame, and a connecting valve is slidably connected inside the limiting groove. An air outlet pipe is provided at one end of the connecting valve. A driving cylinder is fixedly installed at one end of the fixed frame, and an output shaft is symmetrically fixedly installed at one end of the driving cylinder. One end of the output shaft is fixedly installed with the connecting valve. The device is characterized in that a dust suction port for absorbing waste chips is provided at the bottom of the limiting groove, a dust suction pipe is fixedly installed at one end of the fixed frame, and the dust suction pipe is connected through the dust suction port. A baffle is rotatably connected inside the dust suction port, and the baffle is symmetrically rotatably connected inside the dust suction port.

[0007] As a further embodiment of this utility model: a cavity is provided at one end of the fixing frame, and a rotating gear is rotatably connected inside the cavity. Rotating shafts that rotate with the dust suction port are symmetrically fixed at both ends of the baffle, and one end of the rotating shaft passes through the cavity and is fixedly installed with the rotating gear. A sliding rod is slidably connected inside the cavity, and an adjusting rack is fixedly installed at one end of the sliding rod, and the adjusting rack meshes with the rotating gear.

[0008] As a further embodiment of this utility model: an adjusting rack two is fixedly installed at one end of the sliding rod and on the side opposite to the adjusting rack one; a rotating gear two is rotatably connected inside the cavity, and the rotating gear two meshes with the adjusting rack two.

[0009] As a further embodiment of this utility model: the top of the fixed frame is rotatably connected to a rotating shaft, and the rotating shaft is fixedly installed with the rotating gear two through the cavity, and a rotating handle is fixedly installed on the top of the rotating shaft.

[0010] As a further embodiment of this utility model: a limiting gear is fixedly installed on the outer periphery of the rotating shaft, an installation block is fixedly installed on the top of the fixing frame, and a sliding groove is opened at one end of the installation block. The limiting block is slidably connected inside the sliding groove, and the limiting block is adapted to the two tooth grooves of the rotating gear.

[0011] As a further embodiment of this utility model: a reset spring is fixedly installed inside the slide groove, and one end of the reset spring is fixedly installed with the limiting block. One end of the mounting block is slidably connected to a connecting block, and the connecting block passes through the mounting block and is fixedly installed with the limiting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses a vacuum fan in conjunction with a vacuum pipe and a vacuum port to promptly remove debris from the limiting groove using negative pressure suction, preventing the connecting valve from getting stuck due to debris accumulation and ensuring the stable operation of the blowing device. By turning the handle, the opening and closing angle of the baffle can be precisely adjusted through gear and rack transmission. The size of the vacuum port channel can be flexibly adjusted according to the size of the debris, which can enhance the suction capacity for large debris and improve the suction efficiency of small debris, improve the targeting and overall efficiency of vacuuming, reduce manual intervention, and take into account practicality and convenience.

[0014] This invention releases the restriction on the rotating shaft by pulling the connecting block, which causes the limiting block to compress the reset spring and disengage from the tooth groove. This facilitates adjustment of the baffle angle. After adjustment, releasing the connecting block causes the reset spring to automatically drive the limiting block back into the tooth groove, quickly locking the rotating shaft and fixing the positions of the gear, rack, and sliding rod. This effectively resists vibration interference during vacuuming, prevents baffle angle deviation, ensures the vacuum port remains in working condition, guarantees stable vacuuming performance, and is easy to operate, improving the reliability and stability of the device.

[0025] The above-mentioned solution is adopted in which: the connecting valve 6, the driving cylinder 8, the tool holder top plate 2 and the tool holder bottom plate 1 are all prior art referenced in the prior art documents and are not described in detail in this application.

The baffle 12 is made of stainless steel and the suction pipe 11 is made of nylon. The connection is sealed with a silicone sealing ring.

[0026] Reference Figures 1 to 6 The fixed frame 4 has a cavity 13 at one end, and a rotating gear 15 is rotatably connected inside the cavity 13. The baffle 12 has rotating shafts 14 that rotate with the dust suction port 10 symmetrically fixed at both ends, and one end of the rotating shaft 14 passes through the cavity 13 and is fixedly installed with the rotating gear 15. A sliding rod 16 is slidably connected inside the cavity 13. An adjusting rack 17 is fixedly installed at one end of the sliding rod 16 and meshes with the rotating gear 15. An adjusting rack 18 is fixedly installed at one end of the sliding rod 16 and on the side opposite to the adjusting rack 17. A rotating gear 20 is rotatably connected inside the cavity 13 and meshes with the adjusting rack 28.

[0027] The above scheme is adopted: Rotating gear 15 and rotating gear 20 are both made of 45# steel and mesh with adjusting rack 17 and adjusting rack 28.

Top rotating handle 22 is made of ABS engineering plastic with knurled surface treatment, which conforms to ergonomics.

[0028] Reference Figures 1 to 6 A limiting gear 21 is fixedly installed on the outer periphery of the rotating shaft 19. A mounting block 23 is fixedly installed on the top of the fixing frame 4. A sliding groove 24 is opened at one end of the mounting block 23. A limiting block 25 is slidably connected inside the sliding groove 24. The limiting block 25 is adapted to the tooth groove of the rotating gear 20. A return spring 26 is fixedly installed inside the sliding groove 24. One end of the return spring 26 is fixedly installed with the limiting block 25. A connecting block 27 is slidably connected to one end of the mounting block 23. The connecting block 27 passes through the mounting block 23 and is fixedly installed with the limiting block 25.

[0029] The above scheme is adopted: the limiting gear 21 on the outer periphery of the rotating shaft 19 is made of 45# steel, the mounting block 23 is made of steel, the sliding groove 24 and the limiting block 25 are fitted together, the front end of the limiting block 25 meshes with the tooth groove of the limiting gear 21, and the material is steel. The return spring 26 is made of steel to provide locking force. The connecting block 27 is made of PA66+30%GF material and is slidably connected to the mounting block 23. The end is provided with anti-slip texture. When the angle of the baffle 12 is adjusted by rotating the handle 22, the connecting block 27 is released. Under the action of the return spring 26, the limiting block 25 is embedded in the tooth groove of the limiting gear 21 to achieve angle locking.

[0030] The working principle of this utility model is as follows: After connecting the suction pipe 11 to an external vacuum cleaner fan, the vacuum cleaner fan starts and generates negative pressure suction, which is transmitted through the suction pipe 11 to the suction port 10. Under the action of suction, the waste in the limiting groove 5 is sucked into the suction pipe 11 through the suction port 10 and finally collected in the dust collection device of the vacuum cleaner fan. The continuous suction process can promptly remove the waste in the limiting groove 5, avoid the accumulation of waste near the connecting valve 6, reduce the jamming caused by waste entering the sliding part of the connecting valve 6, and ensure the proper functioning of the connecting valve 6. The constant sliding mechanism maintains smooth operation of the entire purging device. Turning the handle 22 rotates the shaft 19, which in turn drives the fixed rotating gear 20 to rotate within the cavity 13. Since the adjusting rack 18 meshes with the rotating gear 20, the rotation of the rotating gear 20 is converted into linear motion of the adjusting rack 18. The adjusting rack 18 drives the sliding rod 16 to slide within the cavity 13, and the adjusting rack 17 at the other end of the sliding rod 16 moves accordingly. Furthermore, because the adjusting rack 17 meshes with the rotating gear 15… The opening and closing of the baffle 12 is adjusted, thereby driving the rotating gear 15 to rotate. The rotating gear 15 drives the baffle 12 to rotate within the suction port 10 via the rotating shaft 14, thus adjusting the opening and closing angle of the baffle 12. By adjusting the angle of the baffle 12, the size of the air intake and debris intake channels of the suction port 10 can be changed to adapt to the absorption needs of debris of different volumes and improve the dust collection efficiency. When the baffle 12 is adjusted to the appropriate angle, the connecting block 27 is pulled. The connecting block 27 drives the limiting block 25 to slide within the slide groove 24 and compress the return spring 26, causing the limiting block 25 to disengage from the limiting spring 26. The tooth groove of the positioning gear 21 is opened, releasing the restriction on the rotating shaft 19. At this time, the rotating handle 22 can be rotated to adjust the baffle 12. After adjustment, the connecting block 27 is released. Under the elastic force of the return spring 26, the limiting block 25 is re-engaged into the tooth groove of the limiting gear 21, locking the rotating shaft 19. This fixes the position of the rotating gear 20, the adjusting rack 18, and the sliding rod 16, keeping the baffle 12 at the adjusted angle. This prevents the baffle 12 from shifting due to vibration or other factors during vacuuming, ensuring stable vacuuming performance.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
