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.

[0017] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects: (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.

[0018] (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.

[0019] (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.

[0024] The following is a detailed description of a grinding device for improving stability during grinding provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are listed as the best and preferred embodiments, and other alternatives can also be used by technicians in some known technical fields; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 12 As shown, an embodiment of the present invention provides a grinding device for improving stability during grinding, comprising a dynamically adjustable bracket group 1, an air guide support module 2 is arranged on the outer surface of the dynamically adjustable bracket group 1, the air guide support module 2 comprises a U-shaped bracket sleeve 21, a grinding sleeve head mechanism 3 is movably arranged on the inner side of the open end of the U-shaped bracket sleeve 21, the grinding sleeve head mechanism 3 comprises a first cylindrical sleeve shell 31, four groups of first grinding wing plate groups 34 with equal spacing are fixedly installed in sequence on the outer annular surface of the first cylindrical sleeve shell 31, and a slot penetrating the shell of the first cylindrical sleeve shell 31 is provided between every two groups of the first grinding wing plate groups 34, and two groups of second grinding wing plate groups 36 which are symmetrically arranged and can be pushed outward are movably arranged in each slot; A first feeding mechanism 4 is also arranged in the cylinder of the first cylindrical casing 31. The first feeding mechanism 4 includes four groups of fan-shaped storage cavities 42 arranged inside the first cylindrical casing 31 and corresponding to the inside and outside of each group of first grinding wing plate groups 34. A second feeding mechanism 6 is also arranged between every two groups of fan-shaped storage cavities 42. The outer surfaces of the second feeding mechanisms 6 are all provided with third grinding wing plate groups 68. Among them, a linkage module 5 is also arranged in the cylinder of the first cylindrical shell 31, and the linkage module 5 is used to link the four groups of second feeding mechanisms 6 to control the second feeding mechanisms 6 to expand outward to push out the second grinding wing plate group 36 and the third grinding wing plate group 68 in turn to switch the grinding ends with different mesh numbers.

[0026] In order to solve the problem of unstable friction caused by repeated docking of the AGV trolley due to frequent replacement of the grinding head and reagents in the prior art, the above-mentioned technical solution is now adopted to solve the problem. The above-mentioned technical solution is mainly composed of a dynamic adjustment bracket group 1, an air guide support module 2, a grinding sleeve 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 flexible robot output end of the AGV trolley in the prior art. It serves as the mounting base of the entire device to ensure the stable fixation of the grinding end. The bracket in the prior art is also equipped with a dynamic adjustment system, which is controlled by the dynamic adjustment system of the servo drive end. Force output, control the telescopic movement of the grinding head, 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, and elastic buffer components and pneumatic buffer components, such as springs or pneumatic elements, can be configured to absorb the instantaneous impact force during the grinding process and avoid rigid collision during work. The whole belongs to the existing technical content, and the air guide support module 2 is a support structure with an overall U-shaped structure, which is used to cover the grinding sleeve mechanism 3, the first feeding mechanism 4 and the second feeding mechanism 6 are configured inside the grinding sleeve mechanism 3, and under the linkage work of the linkage module 5, the whole system can be driven to work intermittently; Specifically, the air guide support module 2 includes a U-shaped bracket sleeve 21, and the grinding sleeve head mechanism 3 includes a first cylindrical sleeve shell 31, and four groups of first grinding wing plate groups 34 with equal spacing are fixedly installed in sequence on the outer annular surface of the first cylindrical sleeve shell 31. The first grinding wing plate group 34 is the initial grinding surface, that is, the rough grinding stage. This stage is to quickly remove burrs, excess glue layers or large defects on the blade surface. Therefore, the first grinding wing plate group 34 is a low-mesh sanding belt structure as a whole, and the mesh range is between 40 and 120 meshes. The material selected is high-hardness abrasives, such as silicon carbide, diamond coating, etc. A slot penetrating the shell of the first cylindrical shell 31 is provided between every two groups of first grinding wing plate groups 34, and two groups of second grinding wing plate groups 36 symmetrically arranged and capable of being pushed outward are movably provided in each slot, wherein the second grinding wing plate group 36 is used for semi-finishing and fine grinding stages. In the semi-finishing and fine grinding stages, the surface is initially smoothed, deep scratches in the rough grinding stage are eliminated, the surface is further refined, and a uniform base is provided for polishing. Therefore, the second grinding wing plate group 36 is a medium-mesh sanding belt structure as a whole, with a mesh range of 120 to 1000 mesh, and is a grinding head made of flexible sandpaper material.

[0027] The first feeding mechanism 4 includes four groups of fan-shaped storage chambers 42 arranged inside the first cylindrical shell 31 and corresponding to the inside and outside of each group of first polishing wing plate groups 34. The fan-shaped storage chambers 42 correspond to the inside and outside of the first polishing wing plate groups 34 in order to dissipate heat for the first polishing wing plate groups 34 on the outside, because in the entire polishing process, the initial grinding stage has the greatest grinding intensity and generates the highest heat. Water-based synthetic cutting fluid is stored in the fan-shaped storage chamber 42. The so-called water-based synthetic cutting fluid is a common product combining cooling and lubrication, which is widely used in the metal processing industry. The water-based synthetic cutting fluid can maintain good fluidity at a lower temperature through a special formula design, thereby effectively taking away heat and having a certain lubrication ability. For non-metallic materials, such as composite materials used for fan blades, after adding polishing particles, it can not only be suitable for rough grinding and semi-fine grinding stages, but also can be polished with polishing particles.

[0028] A second feeding mechanism 6 is also arranged between every two groups of fan-shaped storage cavities 42, and a third grinding wing plate group 68 is arranged on the outer surface of the second feeding mechanism 6, wherein the third grinding wing plate group 68 is used for polishing operation. 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 requires the use of an ultra-fine mesh polishing head with a mesh range of 1100 to 3000 meshes, and is made of non-woven fabric or sponge base.

[0029] 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.

[0030] like Figures 1 to 12As 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.

[0031] 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.

[0032] like Figures 1 to 12As shown, the first feeding mechanism 4 includes a second cylindrical shell 41 fixedly mounted inside the first cylindrical shell 31, the second cylindrical shell 41 is concentric with the first cylindrical shell 31, and four groups of fan-shaped storage cavities 42 with the same angle as the first grinding wing plate group 34 are fixedly mounted on the outer annular surface of the second cylindrical shell 41, and a heat-conducting arc plate 43 that is in contact with the inner wall of the first cylindrical shell 31 is fixedly mounted on the outer surface of each group of fan-shaped storage cavities 42, and a plurality of first metal balls 46 are placed inside the fan-shaped storage cavities 42, and the linkage module 5 includes a main shaft rod 51 movably mounted at the inner center position of the second cylindrical shell 41, and a plurality of cooling fans 52 are fixedly mounted at both side ends of the main shaft rod 51, and a second magnetic block 53 is fixedly mounted on the edge of the blades of each group of cooling fans 52, and the outer side surface of the second magnetic block 53 is in contact with the inner wall of the second cylindrical shell 41 to adsorb the first metal balls 46 placed inside the second cylindrical shell 41.

[0033] Among them, the second cylindrical shell 41 is configured to be concentric with the first cylindrical shell 31, and the four fan-shaped storage chambers 42 are fixedly installed on the outside of the second cylindrical shell 41, and each fan-shaped storage chamber 42 corresponds to the first grinding wing plate group 34 on the outer first cylindrical shell 31 through the heat-conducting arc plate 43, so as to conduct away the heat generated by the grinding process of the first grinding wing plate group 34 in real time. Because as mentioned above, it can be known that the four fan-shaped storage chambers 42 store water-based synthetic cutting fluid with good heat dissipation capacity. During operation, through the high-speed rotation of the main shaft rod 51 arranged at the axial position of the second cylindrical shell 41, the multiple groups of cooling fans 52 on both sides can be used to generate an air duct from the inside to the outside in the cylinder of the second cylindrical shell 41, which can export the internal adsorbed heat and cool the four fan-shaped storage chambers 42, so as to further improve the heat absorption capacity of the water-based synthetic cutting fluid stored in the four fan-shaped storage chambers 42, thereby improving the overall heat dissipation effect and ensuring the stability of the first grinding wing plate group 34 during the grinding stage. At the same time, because the second magnetic block 53 is fixedly installed on the edge of the blade of each group of cooling fans 52, the second magnetic block 53 can repeatedly absorb the first metal ball 46 in the four groups of fan-shaped storage chambers 42 during the rotation process. Specifically, the first metal ball 46 in the four groups of fan-shaped storage chambers 42 can move intermittently under the reciprocating action of the adsorption force, and the water-based synthetic cutting fluid in the four groups of fan-shaped storage chambers 42 can be driven to flow further through the sphere, because the water-based synthetic cutting fluid may be stratified when it is left still for a long time. The flow of the small spheres during the shaking process can promote the circulation and mixing inside the liquid, thereby improving the uniformity of the cutting fluid components, 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 itself in the system absorbs heat from the environment, the stirring of the small spheres can help to distribute the heat more evenly and avoid local overheating.

[0034] like Figures 1 to 12 As shown, the linkage module 5 also includes a first bevel gear sleeve 54 fixedly installed at the middle position of the surface of the main shaft rod 51, and a U-shaped pull-out slot 47 facing the first bevel gear sleeve 54 is opened on the outer shell surface of the second cylindrical sleeve 41 at a position located in the middle of the two fan-shaped storage chambers 42, and a two-way threaded rod 55 is movably installed on the inner side surface of each U-shaped pull-out slot 47, and a second bevel gear sleeve 56 meshing with the first bevel gear sleeve 54 is fixedly installed on the protruding end of each two-way threaded rod 55, and a U-shaped nut pull-out sleeve 57 is meshed on the outer surface of the two-way threaded rod 55, and the U-shaped nut pull-out sleeve 57 on each side passes through the U-shaped pull-out slot 47 on the same side, and a plurality of groups of heat-conducting bent rods 44 connected to the heat-conducting arc plate 43 are fixedly installed inside the fan-shaped storage chamber 42.

[0035] Among them, the configured linkage module 5 is mainly to drive the outer square storage chamber 61 to perform synchronous telescopic movement through the rotation of the main shaft rod 51, which is specifically manifested as the first bevel gear sleeve 54 is rotated by the rotation of the main shaft rod 51, and the second bevel gear sleeves 56 on the four sides are meshed with the first bevel gear sleeve 54, so the synchronized second bevel gear sleeves 56 on the four sides will also rotate, so that the bidirectional threaded rod 55 on each side is rotated, the so-called bidirectional threaded rod 55 is the threaded rod that squeezes the positive and negative threaded grooves in the prior art, and in the process of the bidirectional threaded rod 55 rotating in one direction, the meshed U-shaped nut pull-out sleeve 57 can move up and down along the positive and negative threaded grooves, that is, in the process of the main shaft rod 51 rotating, the U-shaped nut pull-out sleeve 57 will drive the outer square storage chamber 61 to move up and down between the two fan-shaped storage chambers 42. Several groups of heat-conducting curved rods 44 connected to the heat-conducting arc plate 43 arranged inside the fan-shaped storage chamber 42 are for further effective heat extraction.

[0036] like Figures 1 to 12 As shown, the second feeding mechanism 6 includes a square storage cavity 61 fixedly mounted on the outer surface of a U-shaped nut pull-out sleeve 57 passing through a U-shaped pull-out slot 47, the square storage cavity 61 is arranged as a whole in the gap between the two fan-shaped storage cavities 42, and fits with the outer walls of the two fan-shaped storage cavities 42, a plurality of first magnetic blocks 45 are fixedly mounted on the side walls on both sides of the fan-shaped storage cavity 42, a plurality of second metal balls 63 corresponding to the first magnetic blocks 45 on both sides are placed inside the square storage cavity 61, and an extended articulated frame 62 movably connected to the articulated sleeve 37 on the same side is fixedly mounted at the edge positions on both sides of the upper surface of the square storage cavity 61.

[0037] Among them, the configured square storage cavity 61 is arranged as a whole in the gap between the two fan-shaped storage cavities 42, and is fitted with the outer walls of the two fan-shaped storage cavities 42. The fitting with the outer walls of the two fan-shaped storage cavities 42 is arranged on the one hand to rely on the limiters on both sides to ensure the stability of the up and down movement of the square storage cavity 61, and on the other hand to fit the first magnetic block 45. A number of second metal balls 63 corresponding to the first magnetic blocks 45 on both sides are placed inside the square storage cavity 61. Therefore, in the process of the square storage cavity 61 moving back and forth between the two fan-shaped storage cavities 42, under the action of the magnetic blocks with different adsorption poles on both sides, the second metal balls 63 inside will move back and forth synchronously to drive the material stored in the square storage cavity 61 to flow effectively.

[0038] Correspondingly, from the above content, it can be known that in the continuous operation process of the polishing stage, in order to ensure the stability of the polishing operation, it is necessary to add granular materials to the water-based synthetic cutting fluid, so it is necessary to store nanoparticles in the square storage chamber 61, such as aluminum oxide nanoparticles, cerium oxide nanoparticles, etc. in the prior art. 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 surface of the workpiece. The size of the nanoparticles is much smaller than that of traditional abrasives, so it can leave more delicate marks on the surface of the workpiece, significantly improving the surface finish, and for complex-shaped workpieces such as fan blades, this high finish helps to reduce air resistance and extend service life, and the uniform distribution and mild polishing characteristics of the nanoparticles can effectively avoid surface scratches, cracks and other problems that may be caused by traditional abrasives. However, due to their extremely small size, the nanoparticles are easily settled to the bottom of the container due to gravity or agglomeration. The flow of the small spheres, i.e., the second metal spheres 63, will stir the liquid medium, breaking the agglomeration structure between the nanoparticles, thereby effectively preventing sedimentation, and the movement of the small spheres will also produce a turbulent effect in the liquid, accelerating the uniform distribution of the nanoparticles throughout the liquid. This is very important for ensuring the concentration of the nanoparticles each time they are used, especially in situations where high-precision processing is required, 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.

[0039] The extended hinged frame 62 fixedly installed at the edge positions of both sides of the upper surface of the square storage cavity 61 and movably connected to the hinged sleeve 37 on the same side is used to hinge the second grinding wing plate group 36 on the outer side of the hinged sleeve 37. During the semi-fine grinding and fine grinding stages, it is only necessary to keep the first grinding wing plate group 34 on the outer surface of the first cylindrical shell 31 away from the end surface to be ground. The rotation of the main shaft rod 51 drives the U-shaped nut pulling sleeve 57 to reciprocate and push the square storage cavity 61 up and down. The reason why the extended hinged frame 62 on the outer surface of the storage cavity 61 is movably connected with the hinged sleeve 37 on the same side is that the second grinding wing plate group 36 on the outer side of the hinged sleeve 37 is pushed outward reciprocatingly, so that the outer sectional surface of the second grinding wing plate group 36 is higher than the outer sectional surface of the first grinding wing plate group 34. It is only necessary to make the outer sectional surface of the expanded second grinding wing plate group 36 fit the end surface to be polished, and the end surface to be polished can be intermittently polished by the reciprocatingly expanded second grinding wing plate group 36, and semi-finishing and fine grinding processing can be carried out without docking the machine.

[0040] Furthermore, in semi-finishing and finishing processes, this intermittent grinding method can reduce the accumulation of heat on the workpiece surface and the grinding head by periodically interrupting contact, avoid material deformation or performance degradation caused by high temperature, and reduce the continuous contact time between the grinding head and the workpiece, reduce the wear rate, thereby significantly extending the service life of the tool. It is particularly suitable for workpieces with complex shapes such as fan blades, ensuring the consistency and precision 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 surface quality.

[0041] like Figures 1 to 12 As shown, the second feeding mechanism 6 also includes an embedded cavity box 64 fixedly installed at the middle position inside each square storage cavity 61, an electric pumping pump 65 is fixedly installed inside the embedded cavity box 64, a suction duct 66 that penetrates into the square storage cavity 61 is fixedly installed on the output end of the electric pumping pump 65, an electric telescopic rod 67 is fixedly installed at the middle position of the upper surface of the square storage cavity 61, a third polishing wing plate group 68 is fixedly installed on the output end of the electric telescopic rod 67, and the side sectional view of each group of the third polishing wing plate group 68 is a U-shaped structure, and a spray plate 69 is fixedly installed on the opening concave surface of each group of the third polishing wing plate group 68, and a delivery pipe 610 connected to the output end of the electric pumping pump 65 on the same side is fixedly installed on the bottom of the spray plate 69.

[0042] Among them, the configured electric pumping pump 65 is a pump body structure capable of electric pumping according to the prior art, and an embedded cavity box 64 is provided, the purpose of which is to separate a storage chamber for mixing water-based synthetic cutting fluid and grinding particle materials inside the square storage chamber 61. The suction duct 66 on the output end of the electric pumping pump 65 penetrates into the square storage chamber 61, and adsorbs the nanoparticles in the square storage chamber 61 to the embedded cavity box 64. Through the subsequent trigger connection module 7 and the second trigger connection module 8, the water-based synthetic cutting fluid in the outer fan-shaped storage chamber 42 can be introduced into the embedded cavity box 64 to be mixed with the nanoparticles in the embedded cavity box 64 to prepare as a polishing agent. After being prepared as a polishing agent, it can be transported from the embedded cavity box 64 to the spray plate 69 through the delivery pipe 610 on the output end of the electric pumping pump 65. The so-called spray plate 69 is a structural plate with a plurality of spray ports.

[0043] The configured electric telescopic rod 67 is also a telescopic rod structure that can be electrically controlled in the prior art. 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, so that the outer section of the third grinding wing plate group 68 is higher than the outer section of the second grinding wing plate group 36, to cooperate with the third grinding wing plate group 68 to perform reciprocating intermittent grinding.

[0044] In addition, the real-time mixing of nanoparticles with water-based synthetic cutting fluid is compared with the traditional premixing method. In the traditional premixing method, the nanoparticles may gradually lose their dispersibility over time, resulting in a decrease in the performance of the machining fluid. The real-time mixing ensures that the machining fluid is always in the best condition, avoiding performance fluctuations caused by time factors. In addition, the real-time mixing only prepares the right amount of machining fluid when needed, avoiding unnecessary waste and reducing costs.

[0045] like Figures 1 to 12 As shown, the air guide support module 2 also includes an assembly sleeve 22 fixedly installed on both sides of the opening end of the U-shaped bracket sleeve 21, and transparent circular ring side cover plates 32 are pressed and installed on both side ends of the first cylindrical sleeve 31. The first cylindrical sleeve 31 is movably installed on the inner side of the assembly sleeve 22 through the transparent circular ring side cover plates 32 on both sides, and a second circular ring 33 with a leakage opening is fixedly installed on each side of the transparent circular ring side cover plate 32, and a circular ring-shaped fluid infusion catheter connected to the second circular ring 33 with a leakage opening is fixedly installed on the side end of one side of the fan-shaped storage cavity 42, and a circular ring-shaped fluid infusion catheter connected to the second circular ring 33 with a leakage opening is also fixedly installed on the side end of one side of the square storage cavity 61.

[0046] The circular infusion catheter is as shown in the attached manual. Figure 4 , Instruction Manual Figure 5 It can be known that it is a circular sleeve structure composed of four connected together, the outer side of which is connected to the second circular ring with a leak 33. The difference is that a circular fluid infusion conduit connected to the second circular ring with a leak 33 is fixedly installed on the side end of one side of the fan-shaped storage chamber 42, and a circular fluid infusion conduit connected to the second circular ring with a leak 33 on the other side is also fixedly installed on the side end of one side of the square storage chamber 61, that is, the circular fluid infusion conduits extending from the two storage ends extend to both sides of the first cylindrical shell 31 respectively.

[0047] like Figures 1 to 12As shown, the first leak-opening circular ring 25 sealed and connected with the second leak-opening circular ring 33 is fixedly installed on both sides of the open end of the U-shaped bracket sleeve 21, the first leak-opening circular ring 25 is provided with a liquid guide circular opening 29 connected with the second leak-opening circular ring 33, and a sealing circular ring groove 210 is fixedly installed on the other side of each first leak-opening circular ring 25 away from the liquid guide circular opening 29, and a liquid infusion interface module 28 is movably sleeved on one side of the sealing circular ring groove 210, and the liquid infusion interface module 28 includes a liquid guide shell 281 fixedly installed on both sides of the U-shaped bracket sleeve 21, and a circular sleeve edge interface 282 that can be movably sleeved in the sealing circular ring groove 210 on the same side is fixedly installed on the liquid guide shell 281, and a circular opening 283 communicating with the liquid guide circular opening 29 is opened on the side of each liquid guide shell 281.

[0048] Among them, the configured sealing circular ring groove 210 is to flexibly cover the circular ring edge interface 282 on the side of the liquid guiding shell 281. Because the liquid guiding shell 281 is fixed, its outer side can be connected to the corresponding material replenishment tank to replenish the material to the internal square storage cavity 61 and fan-shaped storage cavity 42 in real time. However, during the working process, the grinding end needs to be rotated, so it is separated by the sealing movable sleeve to ensure the stable operation of the liquid replenishment interface.

[0049] like Figures 1 to 12As shown, a first trigger communication module 7 is installed at the middle position of the side of the embedded cavity box 64, and a second trigger communication module 8 is also arranged at a position flush with the first trigger communication module 7 in the middle of the side of the fan-shaped storage cavity 42. The first trigger communication module 7 includes a first infusion cylinder 71 that is connected to the side of the embedded cavity box 64 and passes through the square storage cavity 61. A spherical cavity 72 is fixedly installed on the protruding end of the first infusion cylinder 71. A through hole is opened at the complete axial position of the spherical cavity 72 and a sealing fan-shaped sheet group 73 is fixedly installed in the through hole. The second trigger communication module 8 includes a second infusion cylinder 81 that is connected to the side of the fan-shaped storage cavity 42. The second infusion cylinder 81 and the first infusion cylinder 71 are located on the same vertical horizontal line. The second infusion cylinder 81 faces the second infusion cylinder 81. A spherical circular groove 82 is provided on one side surface of the first infusion cylinder 71, and 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 one side of the spherical circular groove 82, and a sealing block 84 that can seal in the spherical circular groove 82 is fixedly installed on the extended end. The sealing block 84 is in a state of passing through the spherical circular groove 82 as a whole under the elastic force of the reset rod 83, and a first connecting port 85 is provided at the axial position of the sealing block 84 that passes through the spherical circular groove 82, and two groups of second connecting ports 86 are also provided on the outer surface of the first connecting port 85, the second connecting port 86 passes through the side of the sealing block 84 as a whole, and a trigger push rod 87 is also fixedly installed at the axial position of the first connecting port 85.

[0050] Among them, the configured first trigger communication module 7 and the second trigger communication module 8 are respectively arranged on the square storage cavity 61 and the fan-shaped storage cavity 42. On a vertical horizontal line, through the up and down reciprocating movement of the square storage cavity 61, the first trigger communication module 7 is controlled to reciprocate and fit the second trigger communication module 8, so as to achieve an intermittent connection state to introduce the reagent in the fan-shaped storage cavity 42 into the embedded cavity box 64 of the square storage cavity 61, which is specifically manifested as follows: First, in the process of the square storage chamber 61 moving up and down, the spherical cavity 72 on the outside of the first infusion tube 71 will be squeezed into the spherical round-mouth groove 82 on the outside of the second infusion tube 81. After the spherical cavity 72 is squeezed into the spherical round-mouth groove 82, the sealing block 84 will be pushed inward, so that the second connecting port 86 originally on the outside enters into the second infusion tube 81, and the reagent inside the second infusion tube 81 is introduced into the first connecting port 85. After the spherical cavity 72 is squeezed to be completely fitted, the trigger push rod 87 in the first connecting port 85 will push the sealing fan-shaped sheet group 73 at the axial position of the spherical cavity 72 inward, so that the reagent in the first connecting port 85 enters into the first infusion tube 71, and the mixing and introduction of the reagents is completed; Then, after the square storage chamber 61 reciprocates up and down to make the spherical cavity 72 disengage from the spherical round-mouth groove 82, under the action of the reset rod 83, the sealing block 84 will be pushed out again, so that the second connecting port 86 will be re-protruded, and the connection with the inside of the second infusion cylinder 81 will be cut off.

[0051] like Figures 1 to 12 As shown, the U-shaped bracket sleeve 21 is also fixedly installed with a circular concave cover 23 at a position outside the first circular ring with a leakage opening 25, and reserved circular openings 26 are opened at both side ends of the U-shaped bracket sleeve 21 at the position of the center of the circular concave cover 23, and a circular opening communicating with the reserved circular opening 26 is also opened at the center position of the transparent circular ring side cover plate 32, and a servo motor 27 is also fixedly installed on one side end of the outer surface of the U-shaped bracket sleeve 21 through a bracket, and the output end of the servo motor 27 is fixedly connected to the main shaft rod 51, and two L-shaped gas ducts 24 arranged directly above and below the first cylindrical shell 31 are connected and installed on the outside of the circular concave cover 23, and an air outlet facing the first cylindrical shell 31 is opened on the surface of the L-shaped gas duct 24.

[0052] The air guide support module 2 is configured to further utilize the air duct generated by the cooling fan 52 on the main shaft 51 during the operation of the device. Because dust will be generated on the grinding end surface during the grinding process of the device, the L-shaped air duct 24 can be used to further utilize the air duct to blow toward the grinding end to offset the influence of part of the dust. Among them, the configured servo motor 27 is for servo drive to drive the rotation of the main shaft 51, and the reserved circular opening 26 for the output end of the servo motor 27 to penetrate and connect with the main shaft 51 also plays the role of guiding the wind outward. Therefore, the configured servo motor 27 only drives the main shaft 51 to work, and the rotation of the first cylindrical shell 31, that is, the rotation of the entire grinding sleeve 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 manual. Figure 1 As shown, in the process of driving by other servo drive mechanisms, through the effect of servo adjustment, it is necessary to maintain the same frequency rotation as the servo motor 27 in this structure. When the servo motor 27 is needed to drive, it is only necessary to change the rotation frequency of the servo motor 27 to generate a gap difference between the main shaft rod 51 and the first cylindrical shell 31, so that the structure linked to the outside of the main shaft rod 51 can work.

[0053] The method of use provided by the present invention is as follows: When the present invention is used, First, the first cylindrical shell 31 is driven by other servo drive mechanisms, so that the outer first grinding wing plate 34 group contacts the workpiece surface with a low-grit sanding belt for rough grinding, and the servo motor 27 drives the spindle rod, so that the cooling fan 52 disturbs the metal ball in the fan-shaped storage chamber 42 through the magnetic suction block to accelerate the flow and heat dissipation of the water-based cutting fluid, and blows away the dust through the L-shaped air delivery duct 24; Then, the linkage module 5 drives the bidirectional threaded rod 55 to rotate through the bevel gear set, pushing the square storage chamber 61 to move up and down, and uses the extended hinge frame 62 to push the second grinding wing plate group 36 to make it higher than the rough grinding surface, and switches to the medium mesh sand belt for semi-fine grinding and fine grinding, and synchronously mixes the cutting fluid and nanoparticles into polishing fluid through magnetic disturbance and triggering the communication module; Then, the electric telescopic rod 67 pushes out the third polishing wing plate group 68, and sprays the nano-polishing liquid through the ultra-fine polishing surface in cooperation with the spray plate 69, so as to achieve low thermal damage polishing in a high-frequency intermittent contact manner.

[0054] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
