[0002] In the field of modern machining, CNC technology is advancing rapidly, providing strong support for efficient, high-precision production in the manufacturing industry. As a key cutting tool in CNC machining, the performance and quality of CNC inserts directly impact machining accuracy, efficiency, and cost. As the manufacturing industry continues to demand higher levels of machining accuracy and surface quality, precision grinding of CNC insert edges has become a critical step in ensuring their performance.

[0003] In conventional equipment, a motor drives the grinding wheel spindle through a transmission mechanism, causing the grinding wheel to rotate at a high speed. The abrasive grains of the grinding wheel rub against the blade edge, creating a cutting action that removes excess material and achieves the desired size and shape accuracy. However, the internal water spray in conventional equipment is typically located at a fixed position, which does not effectively and uniformly reduce the amount of metal particles floating inside. Therefore, CNC blade edge precision grinding equipment has been proposed to address this issue. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 4The present invention provides an embodiment of a CNC blade edge precision grinding device, comprising a housing 1 and a water tank 11. The housing 1 is the external protective structure of the entire device, made of high-quality steel, and in the shape of a rectangular parallelepiped. It has a certain strength and rigidity, and can effectively resist external impacts and collisions, protecting internal device components from damage. A fixed box 2 is fixedly connected to the interior of the housing 1. The fixed box 2 is a rectangular parallelepiped box structure that provides a sliding guide and limit for the sliding of subsequent structures. A slider 3 is slidably connected to the interior of the fixed box 2. The slider 3 can convert the power generated by the motor 4 into its own linear reciprocating motion, thereby driving the subsequent structure to achieve a cyclical water spraying operation. The left side of the slider 3 is fixedly connected to a nozzle 9, which is a fan-shaped nozzle 9. The fan-shaped nozzle 9 can spray water evenly in a fan-shaped manner, covering a large area, and is suitable for large-area dust reduction and cooling needs. The inside of the housing 1 is fixedly connected to a motor 4, which provides driving force for reciprocating sliding. The driving end of the motor 4 is fixedly connected to a gear 1 5. The main function of the gear 1 5 is to transmit the rotational motion output by the motor 4 to the subsequent structure, and through its special shape, the subsequent structure engages in orbital rotation. The left side of the gear 1 5 is fixedly connected to a connecting plate 6, and the right side of the connecting plate 6 is rotatably connected to a gear 2 7. The rotation of the connecting plate 6 drives the gear 2 7 to revolve around the gear 1 5. The left side of the connecting plate 6 is rotatably connected to a rotating plate 8, which is a key component that converts the orbital motion of the gear 2 7 into the linear reciprocating motion of the slider 3. The rotating plate 8 is a rectangular plate-like structure.

[0033] Reference Figures 2 to 4 The inside of the water tank 11 is fixedly connected to a water pump 12, which is a power device for transporting the water in the water tank 11 to the inside of the equipment. The top of the water pump 12 is fixedly connected to a water pipe 10, which is used to transport the water pumped by the water pump 12 to the nozzle 9. The interior of the shell 1 is provided with a disassembly component for disassembling and replacing the filter structure. The other end of the water pipe 10 is fixedly connected to the top of the nozzle 9. The two ends of the water pipe 10 are usually fixedly connected to the water outlet of the water pump 12 and the top of the nozzle 9 through a joint. The connection part needs to ensure good sealing to prevent water leakage. The left side of the rotating plate 8 is rotatably connected to the right side of the slider 3, and then the rotating plate 8 is rotated back and forth to drive the slider 3 to slide back and forth. The outside of the gear 1 5 is engaged with the outside of the gear 2 7, thereby driving the gear 2 7 to produce orbital revolution.

[0034] Reference Figures 2 to 3The interior of the outer shell 1 is fixedly connected to a support column 18. The support column 18 is usually a columnar structure in the shape of a rectangular parallelepiped. Its main function is to provide a stable installation and support base for the protective shell 19 and the pneumatic clamp 20, so that they can maintain a fixed position during the operation of the equipment and are not affected by equipment vibration or other external forces, thereby ensuring the accuracy and stability of the clamping and grinding of the CNC blades. The front side of the support column 18 is fixedly connected to the protective shell 19. The protective shell 19 can also play a certain safety protection role, preventing the operator from being injured by splashing metal particles processed internally during operation. The interior of the support column 18 is fixedly connected to a pneumatic clamp 20. The pneumatic clamp 20 is a device that uses compressed air as a power source to clamp objects. It has good mechanical properties and wear resistance and can withstand large clamping forces without deformation.

[0035] Reference Figures 2 to 3 The inside of the shell 1 is fixedly connected to an electric slide 16. The main function of the electric slide 16 in the CNC blade edge precision grinding equipment is to provide precise linear motion guidance and position control for the grinding disc 17, so that it can grind the CNC blade at different positions, meet the processing requirements of CNC blades of different shapes and sizes, and improve the processing flexibility and precision. The outside of the electric slide 16 is slidably connected to the grinding disc 17. The grinding disc 17 rotates at high speed and moves along the edge of the CNC blade under the control of the electric slide 16. The edge of the blade is ground to meet the required dimensional accuracy, shape accuracy and surface roughness requirements.

[0036] Reference Figure 2 and Figure 5The disassembly assembly includes a filter plate 21, whose main function is to filter the water flow during the operation of the equipment, intercept impurities such as metal dust and debris in the water, and prevent these impurities from entering components such as the water tank 11 and the water pump 12, thereby ensuring the normal operation of the water circulation system and extending the service life of the equipment. The filter plate 21 is internally fixedly connected to two sleeves 23, whose main function is to provide space for the installation and movement of subsequent structures. During the installation and disassembly process of the filter plate 21, the filter plate 21 and the housing 1 can be quickly connected and separated by working in conjunction with the subsequent structures. The sleeve 23 is internally slidably connected to a push rod 24, and the sleeve 23 is internally movably connected to a plurality of balls 26. The main function of the push rod 24 in the disassembly assembly is to control the engagement state of the balls 26 with the interior of the housing 1 by sliding up and down within the sleeve 23. The bottom of the push rod 24 is fixedly connected to a spring 25. The spring 25 releases the stored energy, pushing the push rod 24 to slide upward, so that the push rod 24 returns to its initial position and re-generates extrusion force on the ball 26. The inside of the shell 1 is fixedly connected to a water pipe 22. The right side of the water pipe 22 is fixedly connected to the inside of the water tank 11. Its main function is to transport the water filtered by the filter plate 21 back to the water tank 11 to achieve water resource recycling.

[0037] Working principle: First, the staff pulls the handle 15 to drive the cabinet door 14 to slide leftward inside the slide 13, opening the interior of the housing 1. Then, the pneumatic clamp 20 clamps the CNC blade to be processed, and controls the rotation and sliding of the grinding disc 17 to grind the data blade. At this time, the switch of the water pump 12 is turned on to draw water to the inside of the nozzle 9 for spraying, reducing the dispersion of metal dust inside the machine. Then the switch of the motor 4 is turned on, and the driving end of the motor 4 drives the gear 1 5 and the connecting plate 6 to rotate, thereby driving the gear 2 7 to revolve around the connecting plate 6, and then pulling the other end of the rotating plate 8 to rotate back and forth, and finally drives the slider 3 to slide back and forth inside the fixed box 2, so that the nozzle 9 on the left side of the slider 3 sprays water reciprocatingly. This design ensures that the water flow can evenly cover the processing area, further enhancing the dust reduction effect. At the same time, the reciprocating water spraying method can also play a certain cooling role, reducing the impact of the heat generated by friction during the grinding process on the CNC blade and equipment components.

[0038] Secondly, the sprayed water is filtered by the filter plate 21 and then guided by the second water pipe 22 to the interior of the water tank 11 for recycling, thereby reducing the waste of water resources.

[0039] Finally, when the filter plate 21 is corroded or clogged by prolonged water flow, the push rod 24 is pressed downward, and the spring 25 generates an elastic force, causing the groove on the push rod 24 to mate with the ball 26, reducing the squeezing force on the ball 26, and the filter plate 21 is slid upward from the bottom end of the housing 1 to be removed. After replacement, the push rod 24 is released, and the spring 25 generates an elastic force to push the push rod 24 upward, generating a squeezing force on the ball 26, forcing the ball 26 out of the sleeve 23 and locking it inside the housing 1, completing the replacement. This design of removing and installing the filter plate 21 by pressing the push rod 24 greatly improves the convenience of equipment maintenance. Operators can quickly complete the replacement of the filter plate 21 without the use of complex tools or tedious operating steps, greatly saving maintenance time.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
