Description

Technical Field

[0001] The invention relates to the technical field of blade grinding, and more particularly to a grinding device capable of improving stability during grinding. Background Art

[0002] During the production process of wind turbine blades, the outer surface of the blades needs to be polished, especially in the automated polishing production line of large wind turbine blades, where the ultra-long blades need to be subjected to multiple stages of continuous operations such as rough grinding, semi-finishing grinding, fine grinding and polishing. Generally, this can be completed in an integrated manner by a flexible robot mounted on an AGV. During the polishing process, the output end of the flexible robot needs to be equipped with a stable unloading device to ensure that the polishing surface is polished with constant force during the polishing process of the blade surface.

[0003] In the prior art, the configured stable unloading device is generally as shown in the attached manual. Figure 1 As shown, it includes a bracket a for connecting the flexible output end of the AGV trolley and a force unloading device b, and a grinding head c with different grinding meshes is assembled through the force unloading device b. The adaptive extension and retraction of the grinding head is achieved through the dynamic adjustment system built into the force unloading device b and the stress feedback control module of the servo drive end.

[0004] However, due to the differences in characteristics of wind turbine blades at different grinding stages, special grinding heads and supporting reagents need to be frequently replaced during actual operation. For example, a high-grinding force grinding wheel is used in combination with coolant in the rough grinding stage, while the polishing stage requires switching to a nano-particle polishing head and synchronously supplying polishing slurry and other multi-stage tool switching tasks. During this process, the AGV needs to stop repeatedly to replace tools and reagent supply lines, resulting in positioning reference offsets and increased system vibrations. Especially when grinding large-sized blades over long strokes, the accumulated error significantly affects the surface consistency, resulting in unstable interface friction states and affecting the final surface quality.

[0019] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0020] (1) This solution achieves seamless connection between rough grinding, fine grinding and polishing processes by adopting a dynamic linkage multi-stage grinding head switching structure. The linkage module is used to drive the second feeding mechanism to expand outward, and the second grinding wing plate group and the third grinding wing plate group are pushed out in turn. The torsion spring outward sleeve rod and the hinged structure are used to automatically switch the working position of the grinding surfaces of different meshes during the rotation process. Different from the traditional technology in the prior art that requires stopping the machine to replace the grinding head, it not only avoids the positioning error caused by repeated docking of the AGV trolley, but also ensures the precise contact sequence of the grinding surfaces at each stage through the height difference design between the rough grinding surface of the first grinding wing plate group and the subsequent wing plate group, effectively reducing the impact vibration during the process conversion and increasing stability.

[0021] (2) The fan-shaped storage chamber and the square storage chamber are magnetically driven to form dynamic stirring of the metal ball, which promotes the uniform distribution of the water-based cutting fluid and the nanoparticles. With the synergistic effect of the heat-conducting arc plate and the cooling fan, a three-dimensional heat dissipation network of axial air duct and radial heat conduction is constructed. In particular, through the periodic connection between the first trigger module and the second trigger module, the real-time mixed supply of the cutting fluid and the polishing particles is realized, which not only avoids the timeliness defect of the traditional premixed liquid, but also accurately controls the amount of polishing agent through intermittent spraying, while reducing material consumption and ensuring the continuous cooling and lubrication effect of the grinding interface.

[0022] (3) The combination of intermittent grinding and flexible polishing processes has achieved a dual improvement in surface processing quality and tool life. In the fine grinding stage, an intermittent contact mode driven by the reciprocating motion of the square storage cavity is adopted. The periodic interruption of the grinding contact effectively disperses the heat accumulation and reduces the abrasive wear rate. In the polishing stage, a combination of nanoparticle suspension and flexible nonwoven fabric polishing surface is introduced. The micro-cutting effect of nanoparticles and the elastic buffering characteristics of the nonwoven substrate are used to form a uniform polishing layer during high-speed rotation, reducing the surface roughness of the workpiece to the mirror level.

[0046] As shown in the figure, in order to clearly implement the structure of the embodiments of the present invention, specific structures and devices are marked in the figure, but this is only for schematic needs and is not intended to limit the present invention to this specific structure, device and environment. According to specific needs, those of ordinary skill in the art can adjust or modify these devices and environments. Detailed implementation manners

[0047] The following describes in detail a grinding device for improving stability during grinding provided by the present invention in combination with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art in some well-known technical fields can also implement them in other alternative ways; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0048] As Figures 1 to 12 shown, an embodiment of the present invention provides a grinding device for improving stability during grinding, including a dynamic adjustment bracket group 1. A gas guiding support module 2 is configured on the outer surface of the dynamic adjustment bracket group 1. The gas guiding support module 2 includes a U-shaped bracket sleeve 21. A grinding sleeve head mechanism 3 is movably arranged inside the opening end of the U-shaped bracket sleeve 21. The grinding sleeve head mechanism 3 includes a first cylindrical housing 31. Four groups of equally spaced first grinding wing plate groups 34 are sequentially fixedly installed on the outer circumferential surface of the first cylindrical housing 31. Grooves penetrating the housing of the first cylindrical housing 31 are opened between every two groups of first grinding wing plate groups 34, and two groups of symmetrically arranged second grinding wing plate groups 36 that can be pushed outwards are movably arranged in each groove;

[0049] Inside the cylinder of the first cylindrical housing 31, a first feeding mechanism 4 is further arranged. The first feeding mechanism 4 includes four groups of fan-shaped storage cavities 42 arranged inside the first cylindrical housing 31 and corresponding to each group of first grinding vane groups 34 inside and outside. And between every two groups of fan-shaped storage cavities 42, a group of second feeding mechanisms 6 is further arranged. Third grinding vane groups 68 are arranged on the outer surfaces of the second feeding mechanisms 6.

[0050] Among them, a linkage module 5 is further arranged inside the cylinder of the first cylindrical housing 31. Through the linkage module 5, the four groups of second feeding mechanisms 6 are linked to control the second feeding mechanisms 6 to expand outwards to sequentially push out the second grinding vane groups 36 and the third grinding vane groups 68 outwards to switch the grinding ends with different mesh numbers.

[0051] To solve the problem of unstable friction caused by the AGV vehicle repeatedly docking due to frequent replacement of grinding heads and reagents in the prior art, the above technical solution is now adopted to solve it. The above technical solution is mainly composed of a dynamic adjustment bracket group 1, an air guide support module 2, a grinding sleeve head mechanism 3, a first feeding mechanism 4, a linkage module 5, and a second feeding mechanism 6. The dynamic adjustment bracket group 1 is a bracket structure rigidly connected to the output end of the flexible robot of the AGV vehicle in the prior art. As the installation base of the whole device, it ensures the stable fixation of the grinding end. A dynamic adjustment system is further arranged inside the bracket in the prior art. Through the power output of the servo drive end, the telescopic movement of the grinding head is controlled. During the working process, the pressure signal of the contact surface between the grinding head and the blade can be monitored in real time and fed back to the servo system. An elastic buffer component and a pneumatic buffer component are also arranged, such as springs or pneumatic components, which can absorb the instantaneous impact force during the grinding process during work to avoid rigid collision. The whole belongs to the prior art content. The air guide support module 2 is a support structure with an overall U-shaped structure for sleeving the grinding sleeve head mechanism 3. The first feeding mechanism 4 and the second feeding mechanism 6 are arranged inside the grinding sleeve head mechanism 3. Under the linkage work of the linkage module 5, the whole system can be driven to work intermittently.

[0052] Specifically, the air guiding support module 2 includes a U-shaped bracket sleeve 21, the grinding sleeve head mechanism 3 includes a first cylindrical housing 31, and four groups of equally spaced first grinding wing plate groups 34 are successively and fixedly installed on the outer circular ring surface of the first cylindrical housing 31. The first grinding wing plate group 34 is the primary grinding surface, that is, the rough grinding stage. This stage is to quickly remove burrs, excess adhesive layers or large defects on the blade surface. Therefore, the first grinding wing plate group 34 is an overall low-mesh sand belt structure, with the mesh number ranging from 40 to 120 meshes, and the material is selected as high-hardness abrasives such as silicon carbide and diamond coating. A notch penetrating the housing of the first cylindrical housing 31 is provided between every two groups of the first grinding wing plate groups 34, and two groups of symmetrically arranged and outwardly pushable second grinding wing plate groups 36 are movably arranged in each notch. The second grinding wing plate group 36 is for semi-finishing and finishing grinding stages. In the semi-finishing and finishing grinding stages, it is to initially flatten the surface, eliminate deep scratches in the rough grinding stage, further refine the surface, and provide a uniform base for polishing. Therefore, the second grinding wing plate group 36 is an overall medium-mesh sand belt structure, with the mesh number ranging from 120 to 1000 meshes, and is a grinding head made of flexible sandpaper material.

[0053] The first feeding mechanism 4 includes four groups of sector-shaped storage cavities 42 arranged inside the first cylindrical housing 31 and corresponding to each group of the first grinding wing plate groups 34 inside and outside. The sector-shaped storage cavities 42 corresponding to the first grinding wing plate groups 34 inside and outside are for dissipating heat to the first grinding wing plate groups 34 on the outside. Because during the entire grinding process, the grinding force in the initial grinding stage is the greatest and the generated heat is also the highest. Water-based synthetic cutting fluid is stored in the sector-shaped storage cavities 42. The so-called water-based synthetic cutting fluid is a common product combining cooling and lubrication, widely used in the metal processing industry. Through special formula design, the water-based synthetic cutting fluid can maintain good fluidity at a lower temperature, thus effectively taking away heat and having a certain lubricating ability at the same time. For non-metallic materials, such as the composite materials used for fan blades, after adding grinding particles, it can not only be applicable to the rough grinding and semi-finishing grinding stages, but also cooperate with the grinding particles for polishing treatment.

[0054] A group of second feeding mechanisms 6 are also arranged between every two groups of the sector-shaped storage cavities 42, and third grinding wing plate groups 68 are arranged on the outer surfaces of the second feeding mechanisms 6. The third grinding wing plate groups 68 are for polishing operations. The so-called polishing operation is to achieve a mirror effect on the outer surface of the blade and improve the aerodynamic performance of the blade. It is necessary to use an ultra-fine mesh polishing and grinding head, with the mesh number ranging from 1100 to 3000 meshes, and is prepared with a non-woven fabric or sponge base.

[0055] During the working process, the four groups of second feeding mechanisms 6 can be linked through the linkage module 5 to control the second feeding mechanism 6 to expand outward, that is, to move the feeding end outward, and the second grinding wing plate group 36 and the third grinding wing plate group 68 can be pushed outward in sequence without stopping to switch the grinding ends with different mesh numbers, so as to solve the problem of unstable friction caused by repeated docking of the AGV trolley due to frequent replacement of grinding heads and reagents in the prior art.

[0056] like Figures 1 to 12 As shown, two groups of torsion spring outward-turning sleeve rods 35 are fixedly installed at the inner end of the notch between each two groups of first grinding wing plate groups 34 on the shell of the first cylindrical shell 31, and a second grinding wing plate group 36 is fixedly connected to the torsion movable end of each group of torsion spring outward-turning sleeve rods 35. The second grinding wing plate group 36 is an arc plate structure as a whole, and a circular grinding sleeve is sleeved on one end of the second grinding wing plate group 36 away from the torsion spring outward-turning sleeve rod 35. The second The grinding wing plate group 36 forms a complete cylindrical structure with the shell of the first cylindrical shell 31 under the torsional force of the torsion spring outward sleeve rod 35, and when the second grinding wing plate group 36 and the shell of the first cylindrical shell 31 form a complete cylindrical structure, the outer section of the circular grinding sleeve on the side end of the second grinding wing plate group 36 is lower than the outer section of the first grinding wing plate group 34, and the second grinding wing plate group 36 is fixedly connected with a hinged sleeve plate 37 on the side facing the center of the first cylindrical shell 31.

[0057] Among them, the configured torsion spring outward-turning sleeve rod 35 is a sleeve rod structure controlled by a torsion spring in the prior art. When in use, the second grinding wing plate group 36 connected to the torsionally movable end of each group of torsion spring outward-turning sleeve rods 35 can always maintain a tightened state without the action of external force, that is, the second grinding wing plate group 36 and the shell of the first cylindrical sleeve 31 form a complete cylindrical structure. In this state, the outer sectional surface of the circular grinding sleeve on the side end of the second grinding wing plate group 36 is lower than the outer sectional surface of the first grinding wing plate group 34, that is, the grinding surface on the side end of the second grinding wing plate group 36 is lower than the outer grinding surface of the first grinding wing plate group 34. When the first cylindrical sleeve 31 rotates at a high speed for grinding, only the outer grinding surface of the first grinding wing plate group 34 can fit the surface to be polished for work, while the grinding surface of the second grinding wing plate group 36 cannot contact the surface to be polished. The purpose is to provide convenience for the phased work of the first grinding wing plate group 34 and the second grinding wing plate group 36.

[0058] like Figures 1 to 12As shown in the figure, the first feeding mechanism 4 includes a second cylindrical sleeve 41 fixedly installed inside the first cylindrical sleeve 31. The second cylindrical sleeve 41 is concentric with the first cylindrical sleeve 31, and four sets of sector-shaped storage cavities 42 with the same angle as the first grinding vane group 34 are fixedly installed on the outer ring surface of the second cylindrical sleeve 41. A heat-conducting arc plate 43 that fits against the inner wall of the first cylindrical sleeve 31 is fixedly installed on the outer surface of each set of sector-shaped storage cavities 42. A number of first metal balls 46 are placed inside each of the sector-shaped storage cavities 42. The linkage module 5 includes a main shaft 51 movably installed at the center position inside the second cylindrical sleeve 41. A plurality of sets of cooling fans 52 are fixedly installed at both ends of the main shaft 51. A second magnetic attraction block 53 is fixedly installed on the edge of the fan blades of each set of cooling fans 52, and the outer side of the second magnetic attraction block 53 fits against the inner wall of the second cylindrical sleeve 41 to adsorb the first metal balls 46 placed inside the second cylindrical sleeve 41.

[0059] Among them, the configured second cylindrical housing 41 is concentric with the first cylindrical housing 31. Four groups of sector storage cavities 42 are fixedly installed on the outer side of the second cylindrical housing 41, and each sector storage cavity 42 corresponds to the first grinding wing plate group 34 on the outer first cylindrical housing 31 through a heat-conducting arc plate 43 to conduct away the heat generated during the grinding process of the first grinding wing plate group 34 in real time. As can be known from the foregoing, the water-based synthetic cutting fluid stored in the four groups of sector storage cavities 42 has good heat dissipation ability. During the working process, through the high-speed rotation of the main spindle rod 51 arranged at the axial center position of the second cylindrical housing 41, a plurality of heat dissipation fans 52 on both sides can generate an air duct from the inside to the outside in the cylinder of the second cylindrical housing 41, which can export the adsorbed heat inside and cool the four groups of sector storage cavities 42 to further improve the heat absorption ability of the water-based synthetic cutting fluid stored in the four groups of sector storage cavities 42, thereby improving the overall heat dissipation effect and ensuring the stability of the grinding stage of the first grinding wing plate group 34. At the same time, because a second magnetic block 53 is fixedly installed on the edge of the fan blade of each group of heat dissipation fans 52, the second magnetic block 53 can repeatedly adsorb the first metal balls 46 in the four groups of sector storage cavities 42 during the rotation process. Specifically, the first metal balls 46 in the four groups of sector storage cavities 42 can move intermittently under the reciprocating action of the adsorption force, and the water-based synthetic cutting fluid in the four groups of sector storage cavities 42 can be further driven to flow by the spheres. Because the water-based synthetic cutting fluid may show a layering phenomenon when standing for a long time. Through the flow of the small spheres during the shaking process, the circulation and mixing inside the liquid can be promoted, thereby improving the uniformity of the cutting fluid composition, and the flow of the small spheres will increase the turbulent effect inside the liquid, thereby accelerating the transfer of heat from the surface of the cutting fluid to the inside. This helps to maintain the overall temperature stability of the cutting fluid, especially when stored or used in a high-temperature environment. Further, for the cutting fluid in this system itself absorbing the heat in the environment, the agitation of the small spheres can help to distribute the heat evenly faster and avoid local overheating.

[0060] As Figures 1 to 12 shown, the linkage module 5 further includes a first bevel gear sleeve 54 fixedly installed at the middle position on the surface of the main spindle rod 51. U-shaped pull slots 47 facing the first bevel gear sleeve 54 are opened at the positions on the outer shell surface of the second cylindrical housing 41 between two sector storage cavities 42, and a bidirectional threaded rod 55 is movably installed on the inner side surface of each U-shaped pull slot 47. A second bevel gear sleeve 56 meshing with the first bevel gear sleeve 54 is fixedly installed at the extending end of each bidirectional threaded rod 55. A U-shaped nut pull sleeve 57 is meshingly sleeved on the outer surface of each bidirectional threaded rod 55, and each U-shaped nut pull sleeve 57 on each side passes out of the U-shaped pull slot 47 on the same side. A plurality of heat-conducting bent rods 44 connected to the heat-conducting arc plates 43 are fixedly installed inside each sector storage cavity 42.

[0061] Among them, the configured linkage module 5 is mainly used to drive the outer square storage cavity 61 to perform synchronous telescopic movement through the rotation of the main shaft rod 51. Specifically, the rotation of the main shaft rod 51 causes the first bevel gear sleeve 54 to rotate, and the second bevel gear sleeves 56 on the four sides are meshed with the first bevel gear sleeve 54. Therefore, the second bevel gear sleeves 56 on the four sides will also rotate synchronously, causing the bidirectional threaded rod 55 on each side to rotate. The so-called bidirectional threaded rod 55 is a threaded rod that extrudes two opposite threaded grooves in the prior art. During the rotation of the bidirectional threaded rod 55 in one direction, the engaged U-shaped nut pull sleeve 57 can reciprocate up and down along the two opposite threaded grooves. That is, during the rotation of the main shaft rod 51, the U-shaped nut pull sleeve 57 will drive the outer square storage cavity 61 to reciprocate up and down between the two fan-shaped storage cavities 42. A number of heat-conducting bent rods 44 connected to the heat-conducting arc plate 43 configured inside the fan-shaped storage cavity 42 are used to further effectively conduct heat.

[0062] As Figures 1 to 12 shown, the second feeding mechanism 6 includes a square storage cavity 61 fixedly installed on the outer surface of the U-shaped nut pull sleeve 57 that passes through the U-shaped pull slot 47. The square storage cavity 61 is integrally arranged in the interval between the two fan-shaped storage cavities 42 and is attached to the outer walls of the two fan-shaped storage cavities 42. A number of first magnetic attraction blocks 45 are fixedly installed on the side walls on both sides of the fan-shaped storage cavity 42. A number of second metal balls 63 corresponding to the adsorption of the first magnetic attraction blocks 45 on both sides are placed inside the square storage cavity 61. Outer extension hinge frames 62 that are movably connected to the hinge sleeve plates 37 on the same side are fixedly installed at the edge positions on both sides of the upper surface of the square storage cavity 61.

[0063] Among them, the configured square storage cavity 61 is integrally arranged in the interval between the two fan-shaped storage cavities 42 and is attached to the outer walls of the two fan-shaped storage cavities 42. The arrangement of attaching to the outer walls of the two fan-shaped storage cavities 42 is for ensuring the stability of the up and down movement of the square storage cavity 61 by relying on the limits on both sides on the one hand, and on the other hand, for attaching to the first magnetic attraction blocks 45. A number of second metal balls 63 corresponding to the adsorption of the first magnetic attraction blocks 45 on both sides are placed inside the square storage cavity 61. Therefore, during the process of the square storage cavity 61 reciprocating up and down between the two fan-shaped storage cavities 42, under the action of the magnetic attraction blocks with different adsorption magnetic poles on both sides, the second metal balls 63 inside will move synchronously in a reciprocating manner to drive the materials stored inside the square storage cavity 61 to flow effectively.

[0064] Correspondingly, as can be known from the above content, during the continuous operation in the polishing stage, in order to ensure the stability of the polishing operation, particulate materials need to be added to the water-based synthetic cutting fluid. Therefore, nanoparticles such as alumina nanoparticles and cerium oxide nanoparticles in the prior art need to be stored in the square storage cavity 61. In the water-based synthetic cutting fluid, that is, after subsequent mixing, the nanoparticles flow with the liquid and form a uniformly distributed grinding layer on the workpiece surface. The size of the nanoparticles is much smaller than that of traditional abrasives. Therefore, finer traces can be left on the workpiece surface, significantly improving the surface finish. And for workpieces with complex shapes such as fan blades, this high surface finish helps to reduce air resistance and extend the service life. Moreover, the uniform distribution and gentle polishing characteristics of the nanoparticles can effectively avoid problems such as surface scratches and cracks that may be caused by traditional abrasives. However, because the nanoparticles are extremely small in size, they are prone to settle to the bottom of the container due to gravity or agglomeration. The flow of the small spheres, that is, the second metal balls 63, will agitate the liquid medium, break the agglomeration structure between the nanoparticles, and thus effectively prevent sedimentation. And the movement of the small spheres will also generate a turbulent effect in the liquid, accelerating the uniform distribution of the nanoparticles throughout the liquid. This is very important for ensuring the nanoparticle concentration each time of use, especially in the case of high-precision machining. And the continuous flow of the small spheres can help maintain the physical and chemical stability of the liquid and extend the service life of the nanoparticle suspension.

[0065] The outstretched hinge frames 62 fixedly installed at both edge positions on the upper surface of the square storage cavity 61 and movably connected to the hinge sleeve plates 37 on the same side are for hinging the second grinding vane groups 36 outside the hinge sleeve plates 37. During the semi-finishing and finishing grinding stages, only need to move the first grinding vane group 34 on the outer surface of the first cylindrical sleeve 31 away from the end surface to be ground. When the U-shaped nut pull-out sleeve 57 is driven by the rotation of the main spindle rod 51 to reciprocally push up and down the square storage cavity 61, due to the fact that the outstretched hinge frames 62 on the outer surface of the square storage cavity 61 are movably connected to the hinge sleeve plates 37 on the same side, the second grinding vane groups 36 outside the hinge sleeve plates 37 will be reciprocally pushed outwards to open, making the outer cutting surfaces of the second grinding vane groups 36 higher than the outer cutting surfaces of the first grinding vane groups 34. Only need to make the outer cutting surfaces of the unfolded second grinding vane groups 36 fit the end surface to be ground, and then the end surface to be ground can be intermittently ground by the reciprocally unfolded second grinding vane groups 36, and the semi-finishing and finishing grinding processing can be carried out without stopping the machine.

[0066] Furthermore, in semi-finishing and finishing processes, by adopting this intermittent grinding method, heat accumulation on the workpiece surface and the grinding head can be reduced through periodic contact interruption, avoiding material deformation or performance degradation caused by high temperature, and reducing the continuous contact time between the grinding head and the workpiece, thereby reducing the wear rate and significantly extending the service life of the tool. This is particularly suitable for workpieces with complex shapes such as fan blades, ensuring the consistency and accuracy of the entire surface while reducing the heat-affected zone. Therefore, although the single processing time may increase slightly, the overall processing efficiency is improved by extending the tool life, reducing rework, and optimizing the surface quality.

[0067] As Figures 1 to 12 shown, the second feeding mechanism 6 further includes an embedded cavity box 64 fixedly installed at the middle position inside each square storage cavity 61. An electric pumping and discharging pump 65 is fixedly installed inside each embedded cavity box 64. A suction conduit 66 penetrating into the square storage cavity 61 is fixedly installed at the output end of each electric pumping and discharging pump 65. An electric telescopic rod 67 is fixedly installed at the middle position on the upper surface of each square storage cavity 61. A third grinding wing plate group 68 is fixedly installed at the output end of each electric telescopic rod 67. The side sectional view of each group of third grinding wing plate groups 68 is a U-shaped structure. A spray plate 69 is fixedly installed on the open concave surface of each group of third grinding wing plate groups 68. A delivery pipe 610 connected to the output end of the electric pumping and discharging pump 65 on the same side is fixedly installed at the bottom of each spray plate 69.

[0068] Among them, the configured electric pumping and discharging pump 65 is a pump body structure capable of electric pumping in the prior art. The purpose of setting the embedded cavity box 64 is to separate a storage cavity for mixing water-based synthetic cutting fluid and grinding particle materials inside the square storage cavity 61. The suction conduit 66 at the output end of the electric pumping and discharging pump 65 penetrates into the square storage cavity 61 to adsorb the nanoparticles in the square storage cavity 61 into the embedded cavity box 64. Through the triggering and connection effects of the subsequent first trigger connection module 7 and the second trigger connection module 8, the water-based synthetic cutting fluid in the outer fan-shaped storage cavity 42 can be introduced into the embedded cavity box 64 to be mixed with the nanoparticles in the embedded cavity box 64 to prepare a polishing reagent. After the polishing reagent is prepared, it can be transported from the embedded cavity box 64 to the spray plate 69 through the delivery pipe 610 at the output end of the electric pumping and discharging pump 65. The so-called spray plate 69 is a structural plate provided with a plurality of spray openings.

[0069] The configured electric telescopic rod 67 is also a telescopic rod structure that can be electrically controlled by existing technologies. Through the electric telescopic control of the electric telescopic rod 67, the third grinding wing plate group 68 at the output end can be extended outward, making the outer cutting surface of the third grinding wing plate group 68 higher than the outer cutting surface of the second grinding wing plate group 36 to cooperate with the third grinding wing plate group 68 for reciprocating intermittent grinding.

[0070] Moreover, the method of mixing nanoparticles with the water-based synthetic cutting fluid in real time, compared with the traditional premixing method, in the traditional premixing method, the nanoparticles may gradually lose their dispersibility over time, resulting in a decline in the performance of the machining fluid. In contrast, real-time mixing ensures that the machining fluid is always in the best state, avoiding performance fluctuations caused by time factors. Additionally, real-time mixing only prepares an appropriate amount of machining fluid when needed, avoiding unnecessary waste and reducing costs.

[0071] As Figures 1 to 12 shown, the air guiding support module 2 further includes assembly socket openings 22 fixedly installed on both sides of the open end of the U-shaped bracket sleeve 21. Transparent circular side cover plates 32 are press-fitted and installed on both side ends of the first cylindrical housing 31. The first cylindrical housing 31 is movably installed inside the assembly socket openings 22 through the transparent circular side cover plates 32 on both sides. And a second circular ring with a leak opening 33 is fixedly installed on each transparent circular side cover plate 32. Circular liquid supplement conduits connected to the second circular ring with a leak opening 33 are fixedly installed on the side ends of one side of the fan-shaped storage cavity 42, and circular liquid supplement conduits connected to the second circular ring with a leak opening 33 on the other side are also fixedly installed on the side ends of one side of the square storage cavity 61.

[0072] Among them, the configured circular liquid supplement conduits, as shown in the attached Figure 4 of the specification, Figure 5 it can be known that it is a structure of four circular ring sleeves connected together. The outer side of this circular ring sleeve structure is connected to the second circular ring with a leak opening 33. The difference is that circular liquid supplement conduits connected to the second circular ring with a leak opening 33 are fixedly installed on the side ends of one side of the fan-shaped storage cavity 42, and circular liquid supplement conduits connected to the second circular ring with a leak opening 33 on the other side are also fixedly installed on the side ends of one side of the square storage cavity 61. That is, the circular liquid supplement conduits extending from the two storage ends extend respectively to both sides of the first cylindrical housing 31.

[0073] As Figures 1 to 12As shown, on both sides of the open end of the U-shaped support sleeve 21, first leaky-ring 25 that is hermetically connected to the second leaky-ring 33 is fixedly installed. A liquid guiding circular opening 29 that is connected to the second leaky-ring 33 is provided on the first leaky-ring 25. On the other side of each first leaky-ring 25 away from the liquid guiding circular opening 29, a sealing ring clamping groove 210 is fixedly installed. A liquid replenishing interface module 28 is movably sleeved on one side of each sealing ring clamping groove 210. The liquid replenishing interface module 28 includes a liquid guiding outer shell 281 fixedly installed on both sides of the U-shaped support sleeve 21. A ring sleeve edge interface 282 that can be movably sleeved in the sealing ring clamping groove 210 on the same side is fixedly installed on each liquid guiding outer shell 281. A circular ring through opening 283 that is communicated with the liquid guiding circular opening 29 is provided on the side surface of each liquid guiding outer shell 281.

[0074] Among them, the configured sealing ring clamping groove 210 is for movably sleeving the ring sleeve edge interface 282 on the side surface of the liquid guiding outer shell 281. Since the liquid guiding outer shell 281 is fixed, a corresponding material replenishing tank can be connected to its outer side to replenish materials to the internal square storage cavity 61 and the fan-shaped storage cavity 42 in real time. However, during the working process, its grinding end needs to rotate. Therefore, it is separated by this sealing movable sleeve to ensure the stable operation of the liquid replenishing interface.

[0075] Such as Figures 1 to 12As shown in the figure, the first trigger connection module 7 is installed at the middle position of the side surface of the embedded cavity box 64, and the second trigger connection module 8 is also configured at the position flush with the first trigger connection module 7 at the middle of the side surface of the sector storage cavity 42. The first trigger connection module 7 includes a first infusion cylinder 71 that is connected to the side surface of the embedded cavity box 64 and penetrates through the square storage cavity 61. A spherical cavity 72 is fixedly installed at the protruding end of the first infusion cylinder 71. A through hole is opened at the complete axial center position of the spherical cavity 72, and a sealed sector piece group 73 is fixedly installed in the through hole. The second trigger connection module 8 includes a second infusion cylinder 81 that is connected to the side surface of the sector storage cavity 42. The second infusion cylinder 81 and the first infusion cylinder 71 are on the same vertical horizontal line. A spherical circular groove 82 is opened on the side surface of the second infusion cylinder 81 facing the first infusion cylinder 71. A reset rod 83 is fixedly installed at the inner center position of the second infusion cylinder 81 through a hollow frame. The reset end of the reset rod 83 extends toward the spherical circular groove 82, and a sealing plug 84 that can seal the spherical circular groove 82 is fixedly installed at the protruding end. Under the elastic force of the reset rod 83, the sealing plug 84 is in a state of protruding from the spherical circular groove 82 as a whole. A first communication port 85 is opened at the axial center position of the sealing plug 84 protruding from the spherical circular groove 82. Two second communication ports 86 are also opened on the outer surface of the first communication port 85. The second communication ports 86 penetrate through the side surface of the sealing plug 84 as a whole, and a trigger push rod 87 is fixedly installed at the axial center position of the first communication port 85.

[0076] Among them, the configured first trigger connection module 7 and the second trigger connection module 8 are respectively arranged on the square storage cavity 61 and the sector storage cavity 42. On a vertical horizontal line, by reciprocating the up and down movement of the square storage cavity 61, the first trigger connection module 7 is controlled to reciprocally fit the second trigger connection module 8, realizing an intermittent connection state to introduce the reagent in the sector storage cavity 42 into the embedded cavity box 64 of the square storage cavity 61. Specifically, it is manifested as follows:

[0077] First, during the reciprocating up and down movement of the square storage cavity 61, the spherical cavity 72 outside the first infusion cylinder 71 will be squeezed into the spherical circular groove 82 outside the second infusion cylinder 81. After the spherical cavity 72 is squeezed into the spherical circular groove 82, the sealing plug 84 will be pushed inward, so that the original outer second communication port 86 enters the inside of the second infusion cylinder 81, leading the reagent inside the second infusion cylinder 81 to the first communication port 85. And the trigger push rod 87 in the first communication port 85 will push the sealed sector piece group 73 at the axial center position of the spherical cavity 72 inward after the spherical cavity 72 is squeezed to be completely fitted, enabling the reagent in the first communication port 85 to enter the first infusion cylinder 71, completing the mixing and introduction of the reagent.

[0078] Then, it reciprocates up and down in the square storage cavity 61. After the spherical cavity 72 is disengaged from the spherical circular orifice groove 82, under the restoring action of the restoring rod 83, the sealing plug 84 will be pushed outwards again, causing the second communication port 86 to penetrate out again, cutting off the communication state with the inside of the second infusion cylinder 81.

[0079] As Figures 1 to 12 shown, at the position where the U-shaped support sleeve 21 is located outside the first leaky-ring 25, a ring-shaped concave cover 23 is fixedly installed. Reserved circular openings 26 are provided at the positions of the two side ends of the U-shaped support sleeve 21 at the center of the ring-shaped concave cover 23. A circular opening communicating with the reserved circular opening 26 is also provided at the center position of the side cover plate 32 of the transparent ring. On one side end of the outer surface of the U-shaped support sleeve 21, a servo motor 27 is fixedly installed through a bracket. The output end of the servo motor 27 is fixedly connected to the main shaft rod 51. Two L-shaped air delivery ducts 24 arranged above and below the first cylindrical sleeve 31 are communicated and installed on the outer sides of the ring-shaped concave cover 23, and air outlet openings facing the first cylindrical sleeve 31 are provided on the surfaces of the L-shaped air delivery ducts 24.

[0080] Among them, the configured air guide support module 2 is to further utilize the air duct generated by the cooling fan 52 on the main shaft rod 51 during the operation of the device. Because during the grinding process of the device, dust will be generated on the grinding end face, and through the conveying action of the L-shaped air delivery duct 24, this air duct can be further utilized to blow towards the grinding end to offset part of the influence of the dust.

[0081] Among them, the configured servo motor 27 is for servo drive to drive the rotation of the main shaft rod 51. The reserved circular opening 26 through which the output end of the servo motor 27 passes and is connected to the main shaft rod 51 also plays a role in guiding air outwards. Therefore, the configured servo motor 27 only drives the main shaft rod 51 to work, and the rotation of the first cylindrical sleeve 31, that is, the rotation of the entire grinding head mechanism 3, is driven by other servo drive mechanisms on the bracket. In the prior art, the configured grinding sleeve shaft is also driven by other servo drive mechanisms. As shown in the attached Figure 1 figure, during the driving process by other servo drive mechanisms, through the servo adjustment, it is required to rotate at the same frequency as the servo motor 27 in this structure. When the servo motor 27 needs to be driven, only by changing the rotation frequency of the servo motor 27, a clearance difference can be generated between the main shaft rod 51 and the first cylindrical sleeve 31, causing the structure linked to the outside of the main shaft rod 51 to work.

[0082] The usage method provided by the present invention is as follows:

[0083] When the present invention is in use,

[0084] First, drive the first cylindrical housing 31 through other servo drive mechanisms, so that the outer first grinding wing plate 34 group contacts the workpiece surface with a low-grit sand belt for rough grinding. The servo motor 27 drives the main shaft rod, so that the cooling fan 52 disturbs the metal balls in the fan-shaped storage cavity 42 through the magnetic attraction blocks to accelerate the flow and heat dissipation of the water-based cutting fluid, and blows the dust through the L-shaped air delivery duct 24;

[0085] Then, the linkage module 5 drives the bidirectional threaded rod 55 to rotate through the bevel gear set, pushes the square storage cavity 61 to move up and down, uses the extended hinge frame 62 to push open the second grinding wing plate group 36 to make it higher than the rough grinding surface, switches to a medium-grit sand belt for semi-finishing and finishing, and synchronously mixes the cutting fluid and nanoparticles into a polishing fluid through magnetic attraction disturbance and triggering the connection module;

[0086] Then, the electric telescopic rod 67 pushes out the third grinding wing plate group 68, sprays the nano-polishing fluid through the ultra-fine polishing surface in cooperation with the spray plate 69, and realizes low-heat-damage polishing in a high-frequency intermittent contact manner.

[0087] The present invention covers any substitutions, modifications, equivalent methods and solutions made within the essence and scope of the present invention. In order to enable the public to have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, well-known methods, processes, procedures, components and circuits, etc. are not described in detail in order to avoid unnecessary confusion to the essence of the present invention.

[0088] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
