[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Example 1: Reference Figure 1-4The milling cutter cleaning device for CNC machine tools shown includes a support plate 1, which serves as the basic support structure for the entire device, providing a stable and reliable mounting platform for other components and ensuring that the components maintain relative positional stability during operation. A rotating cylinder 2 is rotatably connected to the inner side of the support plate 1, allowing the milling cutter to be cleaned at different angles, thus improving the uniformity and integrity of the cleaning effect. A toothed ring 16 is fixedly connected to the outer side of the rotating cylinder 2, which can mesh with an external drive device, providing a power transmission interface for the rotation of the rotating cylinder 2, enabling it to rotate at a predetermined speed and direction. A fixing plate 4 is fixedly connected to the top of the support plate 1. Used to fix and support other auxiliary equipment, providing a stable installation foundation to ensure that these devices do not shake or shift during device operation; a water sprayer 7 is fixedly connected to the side of the fixing plate 4. The water sprayer 7 serves as the main cleaning power source, capable of generating water flow with sufficient pressure. The water spray pipe 8 fixedly connected to its output end precisely guides the water flow into the rotating cylinder 2, rinsing the milling cutters placed inside. The impact force of the water flow removes chips, oil, and other dirt from the surface of the milling cutters, ensuring that the cutting edge and cutter body surface of the milling cutters are effectively cleaned; a slot is opened at the bottom of the inner wall of the rotating cylinder 2, providing space for the installation and movement of the lifting assembly. A lifting ring 11 is slidably connected to the side of the inner wall of the slot, and the lifting ring 11 can be moved in the slot. The vertical position can be adjusted by sliding up and down within the groove. Multiple mounting cylinders 13 are fixedly connected to the top of the lifting ring 11. These mounting cylinders 13 are used to fix the milling cutter. By inserting the milling cutter into the mounting cylinder 13, the milling cutter can remain stable during cleaning and its height can change with the movement of the lifting ring 11 to better adapt to different cleaning needs, such as raising the milling cutter to a suitable height for rinsing by the water sprayer 7 or lowering it to a suitable position for drying. A lifting assembly is provided at the bottom of the rotating cylinder 2. The lifting assembly includes a fixed frame 18 fixedly connected to the bottom of the rotating cylinder 2. The fixed frame 18 provides a stable mounting frame for the hydraulic push rod 17, ensuring that the hydraulic push rod 17 does not shake or deviate during operation. The inner wall of the fixed frame 18 is fixedly connected to a hydraulic push rod 17. As a precise linear drive device, the hydraulic push rod 17 can output a stable thrust or pull force according to the control signal. Its output end is fixedly connected to the bottom of the lifting ring 11. Through the extension and retraction of the hydraulic push rod 17, the vertical lifting height of the lifting ring 11 can be precisely controlled, thereby adjusting the position of the milling cutter in the rotating cylinder 2 and realizing the cleaning operation of the milling cutter at different height levels. For example, the milling cutter can be lifted to the vicinity of the spray nozzle of the water sprayer 7 for powerful rinsing. The side of the fixed plate 4 is fixedly connected to a blower 5. The blower 5 can generate a high-speed airflow. The blower pipe 6 fixedly connected to its output end guides the airflow into the rotating cylinder 2 to dry the cleaned milling cutter.High-speed airflow can quickly remove moisture from the surface of the milling cutter, preventing rust and blowing away any remaining fine dirt, making the surface cleaner and drier for subsequent storage or reuse. A positioning plate 9 is fixedly connected to the side of the fixing plate 4, serving both positioning and auxiliary cleaning functions. Multiple stirring rods 10, fixedly connected to its bottom, rotate inside the rotating cylinder 2 as it rotates. The stirring rods 10 agitate the water flow, creating a complex flow path within the rotating cylinder 2, enhancing the cleaning effect on the milling cutter. For example, when the water flow impacts the stirring rods 10, the rods change the direction and speed of the water flow, allowing it to better reach all corners of the milling cutter, improving the thoroughness of the cleaning. This is especially effective for milling cutters with complex shapes, grooves, or crevices; the agitation of the stirring rods 10 allows the water to penetrate these hard-to-clean areas, effectively removing dirt.
[0024] In this embodiment, the milling cutter is installed inside the mounting cylinder 13. Tool cleaning fluid is introduced into the water sprayer 7 and sprayed out through the water spray pipe 8 to rinse the milling cutter. The motor 19 is controlled to drive the connecting rod 21 and gear 15 to rotate, which in turn drives the rotating cylinder 2 to rotate through the gear ring 16. This causes the lifting ring 11 to drive multiple mounting cylinders 13 and milling cutters to deflect. In conjunction with the water spray pipe 8, the tool cleaning fluid is used to rinse multiple milling cutters. As the tool cleaning fluid is injected, multiple stirring rods 10 stir the tool cleaning fluid, further cleaning the milling cutters. After rinsing, the cleaning fluid is discharged through the output pipe. The hydraulic push rod 17 is controlled to drive the lifting ring 11, mounting cylinder 13, and milling cutter to move upward. As the rotating cylinder 2 rotates, the tool cleaning fluid on the surface of the milling cutter is brushed off under the action of centrifugal force. The blower 5 is controlled to blow air onto the surface of the milling cutter through the blower pipe 6 to accelerate the drying of the milling cutter.
[0025] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a protective cover 3 adapted to the gear ring 16 is fixedly connected to the outer side of the rotating cylinder 2. The protective cover 3 is made of wear-resistant plastic. The main function of the protective cover 3 is to shield and protect the gear ring 16 and the gear 15 meshing with it. During the operation of the device, the meshing motion of the gear ring 16 and the gear 15 will generate a certain amount of friction and collision, and there may be dust, chips and other impurities in the surrounding environment. The protective cover 3 can effectively prevent these impurities from entering the meshing area of the gear ring 16 and the gear 15, avoiding problems such as tooth surface wear and jamming caused by impurities, and extending the service life of the gear ring 16 and the gear 15. At the same time, the wear-resistant plastic material has a certain degree of flexibility while ensuring protective performance, which can reduce the damage to the protective cover 3 itself caused by accidental collisions, and its relatively light weight will not bring excessive additional load to the rotation of the rotating cylinder 2. A positioning frame 20 is fixedly connected to the bottom of the support plate 1, and the positioning frame 20 provides a stable and precise installation position for the motor 19.A motor 19, fixedly connected to the inner wall of the rotating cylinder 2, serves as the power source for its rotation and can output stable torque. A connecting rod 21 is fixedly connected to the output end of the motor 19. The connecting rod 21 passes through the support plate 1, transmitting the power of the motor 19 from the bottom of the support plate 1 to the gear 15 at the top, which is matched with the gear ring 16. Through the meshing transmission between the gear 15 and the gear ring 16, the rotating cylinder 2 can rotate according to the speed and direction set by the motor 19, thereby driving the internal milling cutter to rotate circumferentially, ensuring that all parts of the milling cutter are evenly treated during cleaning and drying. Grooves are provided on the outer sides of both the rotating cylinder 2 and the lifting ring 11. Sealing gaskets 12 are provided on the inner walls of these grooves. The function of the sealing gaskets 12 is to prevent liquid or gas leakage in the gap between the rotating cylinder 2 and the lifting ring 11. During the cleaning process, when the water sprayer 7 sprays water into the rotating cylinder 2, the sealing gaskets 12 effectively prevent water from seeping out from the gap between the rotating cylinder 2 and the lifting ring 11, ensuring that the water flow is concentrated inside the rotating cylinder 2 to wash the milling cutter, improving efficiency. To improve water flow utilization and cleaning effect, a disc 22 is installed inside the empty tank. The disc 22 is fixedly connected to the outside of the rotating cylinder 2 via a connecting frame. The sealing gasket 12 is fixedly connected to the disc 22, providing a stable support base for the sealing gasket 12. This allows the sealing gasket 12 to maintain a stable sealing state under liquid or gas pressure, further enhancing the sealing effect and ensuring the reliability of the seal between the rotating cylinder 2 and the lifting ring 11. Multiple support legs 14 are fixedly connected to the bottom of the support plate 1. The support legs 14 are mainly used to support the entire device, placing it stably on the ground or workbench. They are evenly distributed at the bottom of the support plate 1, distributing the weight of the device and ensuring that the device will not tilt or shake due to instability during operation. This provides a stable foundation environment for the normal operation of the internal components of the device. Especially when the rotating cylinder 2 rotates at high speed and the water sprayer 7 and blower 5 are working, the support legs 14 can effectively resist the unstable factors caused by equipment vibration, enabling the device to operate safely and reliably.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
