To address this issue, blade passivation technology has emerged.

[0003] In the prior art, passivation is typically performed by grinding. First, a suitable grinding tool is selected, the blade is mounted on a dedicated fixture, and then the grinding tool's rotational speed and feed rate are adjusted to ensure uniform contact between the blade and the tool during grinding.

Therefore, a device for uniform blade surface passivation has been proposed to address this issue. Utility Model Content

[0030] 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.

[0031] Reference Figure 1 and Figure 3The utility model provides an embodiment: a blade surface uniform passivation treatment device, including a base 1, which is a frame structure. The material of the base 1 is high-strength steel, which has good stability and load-bearing capacity and can provide a solid foundation support for the entire device. The top of the base 1 is fixedly connected with a processing groove 8. The processing groove 8 is generally a cylindrical or rectangular groove structure. Its material is the same as that of the base 1, and it has sufficient strength and wear resistance. The internal rotation of the processing groove 8 is connected to a rotating disk 9. The rotation of the rotating disk 9 drives the blade to be processed to revolve. The interior of the rotating disk 9 is fixedly connected with a rack ring 10. The rack ring 10 is an annular rack structure. By engaging with the subsequent structure, the power is transmitted to the rotating disk 9, thereby realizing the rotational movement of the rotating disk 9. The internal rotation of the rotating disk 9 is connected to multiple rotating shafts 13. The rotating shafts 13 can rotate inside the rotating disk 9 to drive the top structure to rotate. The external sliding connection of the rotating shaft 13 is connected to the blade seat 19. The blade seat 19 is made of stainless steel and has good rigidity and stability to ensure that the position of the blade will not shift during processing. The blade seat 19 is usually a cylindrical block structure. The internal shape and size of the blade seat 19 will be designed according to the shape and size of the blade to be processed to ensure that the blade can be firmly placed therein and will not loosen or shift during the passivation process. The interior of the blade seat 19 is provided with a blanking component for automatic ejection, and the outside of the rotating shaft 13 is fixedly connected to gear 2 14, and the far side of multiple gears 2 14 is meshed with the inside of the rack ring 10. The rotation of gear 2 14 drives the rack ring 10 to rotate, thereby realizing the effect of revolution. The bottom of the base 1 is fixedly connected to a motor 11, and the driving end of the motor 11 is fixedly connected to gear 12. The rotation of the driving end of the motor 11 drives gear 12 to rotate, thereby driving gear 2 14 to reverse and drive the top blade seat 19 to revolve. The outside of gear 12 is meshed with the close side of multiple gears 2 14, transmitting the rotational power and realizing self-rotation.

[0032] Reference Figures 1 to 2, the top of the base 1 is fixedly connected to a support column 2, which is usually a cylindrical or prismatic metal structure, and its material is generally made of high-strength steel with good rigidity and stability. The support column 2 can effectively bear the weight from the upper structure and transfer it to the base 1, playing the role of supporting and stabilizing the entire grinding structure. The top of the support column 2 is fixedly connected to a CNC machine head 3, which integrates an advanced CNC system, including a processor, memory, controller, etc., which can achieve precise control and monitoring of the equipment's operating parameters. The front side of the CNC machine head 3 is fixedly connected to a display screen 4, which is generally a touch screen, used to display the equipment's operating status, parameter settings, fault alarms and other information. The size and resolution of the display screen 4 will be selected according to the convenience of operation and the requirements of the display content, so that the operator can clearly and intuitively understand the working conditions of the equipment and perform corresponding operations and adjustments. The bottom of the CNC machine head 3 is fixedly connected to a telescopic rod 5. During the blade passivation process, the telescopic rod 5 can adjust the subsequent structure to a suitable height according to different blade sizes and passivation process requirements to ensure that the grinding rod 7 can make good contact with the blade surface and achieve effective passivation. The driving end of the telescopic rod 5 is fixedly connected to a rotating disk 6. The main function of the rotating disk 6 is to drive the subsequent structure to rotate, thereby grinding and passivating the blade surface. A plurality of grinding rods 7 are fixedly connected to the bottom of the rotating disk 6. The material of the grinding rods 7 is aluminum oxide abrasive. The aluminum oxide abrasive particles can gradually remove the tiny burrs and sharp parts on the blade edge through friction with the blade edge, making the blade edge smoother and rounder.

[0033] Reference Figures 3 and 4The blanking component includes a push plate 16, which is usually a flat plate structure, and its shape may be square. The push plate 16 is generally made of metal and has a certain strength and rigidity. It can withstand pushing the blade to blank and realize automatic blanking. The outside of the push plate 16 is fixedly connected to two sliders 17, and the outside of the slider 17 is slidably connected to the inside of the blade seat 19. The slide structure inside the blade seat 19 not only provides a movement track for the slider 17, but also plays a role in limiting the movement direction of the slider 17, so that the push plate 16 can only move up and down in the vertical direction, thereby accurately pushing the blade out of the blade seat 19. The outside of the rotating shaft 13 is fixedly connected to a limit plate 15, and the outside of the limit plate 15 is slidably connected to the inside of the blade seat 19. The main function of the limit plate 15 is to limit the blade seat 19 in the process of the rotating shaft 13 driving the blade seat 19 to rotate and move up and down, preventing the blade seat 19 from falling off the rotating shaft 13 or excessive displacement. The outside of the rotating shaft 13 is provided with a spring 18, the top of the spring 18 is fixedly connected to the bottom of the blade seat 19, and the bottom of the spring 18 is fixedly connected to the top of the rotating disk 9. When the blade seat 19 slides downward, the internal push plate 16 pushes the blade out, automatically unloading, compressing the spring 18, so that the spring 18 stores elastic potential energy. After the blade seat 19 is released, the spring 18 releases the stored energy and pushes the blade seat 19 to reset, facilitating the next processing and unloading.

[0034] Working Principle: First, the processing personnel place the CNC cutter head to be passivated inside the blade holder 19. At this time, the switch of the motor 11 is turned on. The driving end rotates to drive gear 12 to rotate, thereby driving multiple gears 2 14 to rotate, and driving the blade holder 19 at the top of the rotating shaft 13 to rotate, realizing the self-rotation of the CNC cutter head. At the same time, the rotation of multiple rotating shafts 13 drives the rack ring 10 to produce a reverse motion, thereby driving the rotating disk 9 to rotate inside the processing groove 8. Then the switch of the telescopic rod 5 is turned on. The driving end of the telescopic rod 5 extends downward, driving the rotating disk 6 and the grinding rod 7 at the bottom to contact the surface of the CNC cutter head. Then the rotating disk 6 is turned on to drive the bottom grinding rod 7 to rotate and perform rotational friction grinding with the bottom CNC cutter head. The gear transmission system driven by the motor 11 enables the CNC cutter head to not only rotate but also revolve, thus ensuring that all parts of the cutter head are fully polished. The combination of self-rotation and other movements avoids the local omission or unevenness that may occur during the passivation process, and improves the overall quality and consistency of the cutter head passivation.

[0035] Secondly, after grinding is completed, the blade seat 19 is slid downward to squeeze the spring 18 on the lower side, generating an elastic reaction force, thereby driving the push plate 16 and the two sliders 17 to slide upward relative to each other inside the blade seat 19, pushing the processed and ground data cutter head out from the inside of the blade seat 19 to complete the unloading. At this time, the blade seat 19 is released again, and the reaction force of the spring 18 pushes the blade seat 19 to slide upward, completing the reset of the blade seat 19, facilitating the next processing and unloading, greatly simplifying the unloading process, improving the unloading efficiency, and reducing the time and energy spent by the processing personnel in the unloading link. In the scenario of large-scale production or continuous processing, this efficient unloading method can significantly speed up the production rhythm and improve the overall production efficiency.

[0036] 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.
