Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of blade grinding, and more specifically, to a grinding device with improved grinding stability.BACKGROUND

[0002] During production, the outer surfaces of wind turbine blades require grinding. Especially in automated production lines for large wind turbine blades, the front and back of ultra-long blades require multi-stage continuous operations, such as rough grinding, semi-finish grinding, finish grinding, and polishing. Generally, these operations can be integrated by a flexible robot mounted on an automatic guided vehicle (AGV). In the grinding process, an output end of the flexible robot needs to be equipped with a stable force relief device to ensure that the grinding surface of the blade is ground by constant force.

[0003] In the prior art, the stable force relief device is generally as shown in FIG. 1, including a force relief device b and a bracket a that is connected to a flexible output end of the AGV. Different grinding heads c with different grinding meshes are assembled through the force relief device b. Through a built-in dynamic adjustment system of the force relief device b, the adaptive extension and retraction of the grinding head are achieved using a stress feedback control module on a servo driving end.

[0004] However, due to different characteristics of wind turbine blades across different grinding stages, dedicated grinding heads and matching agents need to be frequently replaced during actual operation. For example, the rough grinding stage employs a high grinding force wheel in conjunction with a coolant, while the polishing stage requires a nano-particle polishing head with simultaneous supply of polishing slurry, involving multi-stage tool changes. In this process, the AGV needs to repeatedly stop for tool changes and reagent supply line connections, leading to positioning reference offset and system vibration increase. Especially during long-stroke grinding of large blades, error accumulation adversely affects surface consistency, leading to unstable interfacial friction and compromising the final surface quality.SUMMARY

[0017] Compared to the prior art, the above technical solutions provided by the present invention have at least the following beneficial effects: (1) The dynamic linked multi-level grinding head switching structure achieves seamless connection of rough grinding, finish grinding, and polishing. The linkage module drives the second feeding mechanisms to expand outward to sequentially push out the second grinding wing plate sets and the third grinding wing plate sets, and the cooperation between the torsion spring outward turning sleeve rods and the hinge structures allows automatic switching of working positions on grinding surfaces with different mesh numbers during rotation. Different from the conventional technology that requires shutdown to replace the grinding head, this grinding device not only avoids positioning errors caused by repeated stop of an AGV, but also ensures a precise contact sequence of grinding surfaces at all stages by designing the height difference between the rough grinding surface of the first grinding wing plate set and the subsequent wing plate set, thereby effectively reducing impact vibration during process conversion and increasing stability. (2) The metal balls are magnetically driven to form dynamic agitation in the sector-shaped storage chambers and the square storage chambers, promoting uniform distribution of a water-based cutting fluid and nano-particles. The synergistic effect of the heat-conducting arc plate and the cooling fans constitutes a three-dimensional heat dissipation network with axial air ducts and radial heat conduction. Especially the periodic connection between the first trigger module and the second trigger module achieves real-time mixing and supply of the cutting fluid and polishing particles, thereby avoiding effectiveness defects of conventional premixed fluids. The dosage of a polishing agent is accurately controlled through intermittent spraying, thereby reducing material consumption and ensuring continuous cooling and lubrication of a grinding interface. (3) The combination of intermittent grinding and flexible grinding processes achieves a dual improvement on surface processing quality and tool life. The finish grinding stage employs an intermittent contact mode driven by the reciprocating movement of the square storage chambers, where the periodically interrupted grinding contact effectively disperses heat accumulation and reduces the wear rate of abrasives. A combination of a nano-particle suspension and a flexible non-woven fabric grinding surface is introduced in the polishing stage, to form a uniform grinding layer during high-speed rotation through the micro-cutting effect of nano-particles and the elastic buffering characteristic of a non-woven substrate, thereby reducing the surface roughness of a workpiece to a mirror level.

[0021] A grinding device with improved grinding stability, provided by the present invention, will be described in detail below in conjunction with the drawings and specific embodiments. It is also noted here that, in order to provide a more detailed description of the embodiments, the following embodiments are the optimal and preferred embodiments. Those skilled in the art may also adopt other alternative implementations. Furthermore, the drawings are merely intended to describe the embodiments more specifically and are not intended to provide specific limitations to the present invention.

[0022] As shown in FIG. 1 to FIG. 12, an embodiment of the present invention provides a grinding device with improved grinding stability, including a dynamic adjustment bracket set 1, where an air-guiding support module 2 is arranged on an outer surface of the dynamic adjustment bracket set 1, and the air-guiding support module 2 includes a U-shaped bracket sleeve 21; a grinding sleeve head mechanism 3 is movably provided on an inner side of an open end of the U-shaped bracket sleeve 21, the grinding sleeve head mechanism 3 includes a first cylindrical sleeve shell 31, and four equidistant first grinding wing plate sets 34 are fixedly mounted in sequence on an outer ring surface of the first cylindrical sleeve shell 31; a slot penetrating a shell body of the first cylindrical sleeve shell 31 is formed between every two first grinding wing plate sets 34, and two second grinding wing plate sets 36 that are symmetrically arranged and are capable of being pushed outward are movably provided in each slot;

[0023] A first feeding mechanism 4 is further arranged in a cylinder of the first cylindrical sleeve shell 31, the first feeding mechanism 4 includes four groups of sector-shaped storage chambers 42 arranged inside the first cylindrical sleeve shell 31 and corresponding to the inside and outside of the respective first grinding wing plate sets 34, a set of second feeding mechanism 6 is further arranged between every two groups of sector-shaped storage chambers 42, and a third grinding wing plate set 68 is arranged on an outer surface of the second feeding mechanism 6;

[0024] A linkage module 5 is further arranged inside the cylinder of the first cylindrical sleeve shell 31, and the linkage module 5 links the four sets of second feeding mechanisms 6, to control the second feeding mechanisms 6 to expand outward to sequentially push out the second grinding wing plate sets 36 and the third grinding wing plate sets 68, in order to switch grinding ends with different mesh numbers.

[0025] The above technical solution is employed to solve the problem of friction instability caused by repeated stop of an AGV due to frequent replacement of grinding heads and reagents in the prior art. The above grinding device is mainly composed of the dynamic adjustment bracket set 1, the air-guiding support module 2, the grinding sleeve head mechanism 3, the first feeding mechanism 4, the linkage module 5, and the second feeding mechanism 6. The dynamic adjustment bracket set 1 is a bracket structure rigidly connected to an output end of a flexible robot of the AGV in the prior art, and serves as a mounting base of the entire device to ensure stable fixation of the grinding end; a dynamic adjustment system is further arranged inside the bracket in the prior art, and the expansion and contraction of a grinding head are controlled through power output of a servo driving end; during working, pressure signals of a grinding head and blade contact surface can be monitored in real time and fed back to a servo system; an elastic buffer component or a pneumatic buffer component, such as a spring or a pneumatic component, is further arranged to absorb instantaneous impact force during grinding, so as to avoid rigid collisions. The overall structure of the dynamic adjustment bracket set 1 belongs to the prior art. The whole air-guiding support module 2 is a U-shaped support structure, and is used to mount 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 of the linkage module 5, the entire system can be driven to work intermittently;

[0026] Specifically, the air-guiding support module 2 includes the U-shaped bracket sleeve 21, the grinding sleeve head mechanism 3 includes the first cylindrical sleeve shell 31, and the four equidistant first grinding wing plate sets 34 are fixedly mounted in sequence on the outer ring surface of the first cylindrical sleeve shell 31, where the first grinding wing plate sets 34 provide initial grinding surfaces for a rough grinding stage. The rough grinding stage is to quickly remove burrs, excess adhesive layers, or large defects from the blade surface. Therefore, the first grinding wing plate sets 34 are of sand belt structures with a small mesh number ranging from 40 to 120 meshes, and are made of a high-hardness abrasive, such as silicon carbide or diamond coating. The slot penetrating the shell body of the first cylindrical sleeve shell 31 is formed between every two first grinding wing plate sets 34, and the two second grinding wing plate sets 36 that are symmetrically arranged and are capable of being pushed outward are movably provided in each slot, where the second grinding wing plate sets 36 are used for semi-finish grinding and finish grinding stages. The semi-finish grinding and finish grinding stages are for preliminarily leveling the surface, eliminating deep scratches in the rough grinding stage, further refining the surface, and providing a uniform substrate for polishing. Therefore, the entire second grinding wing plate sets 36 are of sand belt structures with a medium mesh number ranging from 120 to 1000 meshes, with grinding heads made of abrasive paper.

[0027] The first feeding mechanism 4 includes the four groups of sector-shaped storage chambers 42 arranged inside the first cylindrical sleeve shell 31 and corresponding to the inside and outside of the respective first grinding wing plate sets 34, where the sector-shaped storage chambers 42 correspond to the inside and outside of the first grinding wing plate sets 34 to dissipate heat of the outer first grinding wing plate sets 34, because in the entire grinding process, the initial grinding stage involves the largest grinding force and generates the highest amount of heat. A water-based synthetic cutting fluid is stored in the sector-shaped storage chambers 42. The water-based synthetic cutting fluid is a common product that combines cooling and lubrication, and is widely used in the metal processing industry. Through a special formula design, the water-based synthetic cutting fluid can maintain good fluidity at a relatively low temperature, thereby effectively removing heat and providing certain lubrication capability. For a non-metallic material, such as a composite used in wind turbine blades, after grinding particles are added, the water-based synthetic cutting fluid can not only be suitable for rough and semi-finish grinding stages, but also can cooperate with the grinding particles for polishing.

[0028] The set of second feeding mechanism 6 is further arranged between every two groups of sector-shaped storage chambers 42, and the third grinding wing plate set 68 is arranged on the outer surface of the second feeding mechanism 6, where the third grinding wing plate set 68 is used for polishing operation. The polishing operation is to achieve a mirror effect on the outer surface of the blade and improve the aerodynamic performance of the blade. Therefore, grinding heads with an ultra-small mesh number ranging from 1100 to 3000 meshes, made of a non-woven fabric or sponge substrate, are required.

[0029] During working, the linkage module 5 can link the four sets of second feeding mechanisms 6, to control the second feeding mechanisms 6 to expand outward, i.e., move their feeding ends outward, to sequentially push out the second grinding wing plate sets 36 and the third grinding wing plate sets 68 in order to switch grinding ends with different mesh numbers on the premise of no shutdown, thereby solving the problem of friction instability caused by repeated stop of the AGV due to frequent replacement of grinding heads and reagents in the prior art.

[0030] As shown in FIG. 1 to FIG. 12, two groups of torsion spring outward turning sleeve rods 35 are fixedly mounted at an inner side end of a slot between every two first grinding wing plate sets 34 on the shell body of the first cylindrical sleeve shell 31, and the second grinding wing plate set 36 is fixedly connected to a torsion active end of each group of torsion spring outward turning sleeve rods 35; the second grinding wing plate set 36, as a whole, has a circular arc plate structure, and a circular grinding sleeve is respectively fitted on a side end of the second grinding wing plate set 36 that is away from the torsion spring outward turning sleeve rods 35; the second grinding wing plate set 36 and the shell body of the first cylindrical sleeve shell 31 form a complete cylindrical structure under the torsion force of the torsion spring outward turning sleeve rods 35, and an outer section of the circular grinding sleeve on the side end of the second grinding wing plate set 36 is lower than an outer section of the first grinding wing plate set 34 when the second grinding wing plate set 36 and the shell body of the first cylindrical sleeve shell 31 form the complete cylindrical structure; and a hinged sleeve plate 37 is respectively fixedly connected to a side of the second grinding wing plate set 36 that faces a center of the first cylindrical sleeve shell 31.

[0031] The torsion spring outward turning sleeve rods 35 are sleeve rod structures controlled by torsion springs in the prior art. When in use, the second grinding wing plate set 36 connected to the torsion active end of each group of torsion spring outward turning sleeve rods 35 can always maintain a tightened state without external force, that is, the second grinding wing plate set 36 and the shell body of the first cylindrical sleeve shell 31 form the complete cylindrical structure. In this state, the outer section of the circular grinding sleeve on the side end of the second grinding wing plate set 36 is lower than the outer section of the first grinding wing plate set 34, that is, the grinding surface on the side end of the second grinding wing plate set 36 is lower than the outer grinding surface of the first grinding wing plate set 34. In the state where the first cylindrical sleeve shell 31 rotates at a high speed for grinding, only the outer grinding surface of the first grinding wing plate set 34 can fit a surface to be ground for work, while the grinding surface of the second grinding wing plate set 36 cannot come into contact with the surface to be ground, in order to provide convenience for the phased work of the first grinding wing plate set 34 and the second grinding wing plate set 36.

[0032] As shown in FIG. 1 to FIG. 12, the first feeding mechanism 4 includes a second cylindrical sleeve shell 41 fixedly mounted inside the first cylindrical sleeve shell 31, the second cylindrical sleeve shell 41 is concentric with the first cylindrical sleeve shell 31, and the four groups of sector-shaped storage chambers 42, arranged at the same angle as the first grinding wing plate sets 34, are fixedly mounted on an outer ring surface of the second cylindrical sleeve shell 41; a heat-conducting arc plate 43 fitting an inner wall of the first cylindrical sleeve shell 31 is respectively fixedly mounted on an outer surface of each group of sector-shaped storage chambers 42, and a plurality of first metal balls 46 are placed inside the sector-shaped storage chamber 42 respectively; the linkage module 5 includes a spindle rod 51 movably mounted at a center position inside the second cylindrical sleeve shell 41, multiple groups of cooling fans 52 are respectively fixedly mounted at two side ends of the spindle rod 51, and a second magnetic block 53 is respectively fixedly mounted on a fan blade edge of each group of cooling fans 52; and an outer surface of the second magnetic block 53 fits the inner wall of the second cylindrical sleeve shell 41 to attract the first metal balls 46 placed inside the second cylindrical sleeve shell 41.

[0033] The second cylindrical sleeve shell 41 is concentric with the first cylindrical sleeve shell 31, the four groups of sector-shaped storage chambers 42 are fixedly mounted on the outside of the second cylindrical sleeve shell 41, and each sector-shaped storage chamber 42 corresponds to the first grinding wing plate set 34 on the outer first cylindrical sleeve shell 31 through the heat-conducting arc plate 43, to guide away the heat generated in the grinding process of the first grinding wing plate set 34 in real time. As mentioned above, the four groups of sector-shaped storage chambers 42 store the water-based synthetic cutting fluid with good heat dissipation capability. During working, through the high-speed rotation of the spindle rod 51 arranged at the axis position of the second cylindrical sleeve shell 41, the multiple groups of cooling fans 52 on both sides can produce an air duct from inside to outside inside the cylinder of the second cylindrical sleeve shell 41, to guide out absorbed heat inside and cool down the four groups of sector-shaped storage chambers 42, thereby further improving the heat absorption capacity of the water-based synthetic cutting fluid stored in the four groups of sector-shaped storage chambers 42, improving the overall heat dissipation effect, and ensuring the stability of the first grinding wing plate set 34 in the grinding stage. Meanwhile, the second magnetic block 53 is fixedly mounted on the fan blade edge of each group of cooling fans 52, and the second magnetic blocks 53 can repeatedly attract the first metal balls 46 in the four groups of sector-shaped storage chambers 42 during rotation. Specifically, the first metal balls 46 in the four groups of sector-shaped storage chambers 42 can move intermittently under the back and forth action of this adsorption force, and the balls drive the water-based synthetic cutting fluid in the four groups of sector-shaped storage chambers 42 to further flow, because the water-based synthetic cutting fluid may experience stratification during long-term standing. The flow of the balls during shaking can promote the circulation and mixing inside the fluid, thereby improving the uniformity of the cutting fluid composition. In addition, the flow of the balls also increases the turbulence effect inside the fluid, 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 high-temperature environments. Furthermore, as the cutting fluid absorbs heat from the environment in the system, the stirring of the balls can help distribute heat more evenly to avoid local overheating.

[0034] As shown in FIG. 1 to FIG. 12, the linkage module 5 further includes a first conical gear sleeve 54 fixedly mounted at a middle position of a surface of the spindle rod 51, and a U-shaped pull slot 47 facing the first conical gear sleeve 54 is respectively formed on an outer shell surface of the second cylindrical sleeve shell 41 at a middle position of each of the two sector-shaped storage chambers 42; a bidirectional threaded rod 55 is respectively movably mounted on an inner surface of each U-shaped pull slot 47; a second conical gear sleeve 56 engaged with the first conical gear sleeve 54 is respectively fixedly mounted on an extended end of each bidirectional threaded rod 55; an outer surface of the bidirectional threaded rod 55 is respectively engaged with a U-shaped nut pull sleeve 57, and the U-shaped nut pull sleeve 57 on each side extends respectively outward from the U-shaped pull slot 47 on the same side; and multiple groups of heat-conducting bent rods 44 connected to the heat-conducting arc plate 43 are respectively fixedly mounted inside the sector-shaped storage chamber 42.

[0035] The linkage module 5 is mainly arranged to drive an outer square storage chamber 61 to extend and retract synchronously through the rotation of the spindle rod 51. Specifically, the first conical gear sleeve 54 rotates through the rotation of the spindle rod 51, and the second conical gear sleeves 56 on four sides mesh with the first conical gear sleeve 54. Therefore, the synchronous second conical gear sleeves 56 on the four sides also rotate, and the bidirectional threaded rod 55 on each side rotates. The bidirectional threaded rod 55 is a threaded rod that squeezes two front and back threaded slots 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 vertically along the two front and back threaded slots, that is, during the rotation of the spindle rod 51, the U-shaped nut pull sleeve 57 drives the outer square storage chamber 61 to reciprocate vertically between the two sector-shaped storage chambers 42. The multiple groups of heat-conducting bent rods 44 connected to the heat-conducting arc plate 43 are arranged inside the sector-shaped storage chambers 42 to further effectively dissipate heat.

[0036] As shown in FIG. 1 to FIG. 12, the second feeding mechanism 6 includes a square storage chamber 61 fixedly mounted on an outer surface of the U-shaped nut pull sleeve 57 that extends out from the U-shaped pull slot 47, and the whole square storage chamber 61 is arranged in the space between the two sector-shaped storage chambers 42 and contacts outer walls of the two sector-shaped storage chambers 42; a plurality of first magnetic blocks 45 are respectively fixedly mounted on two side walls of the sector-shaped storage chamber 42; a plurality of second metal balls 63 correspondingly attracting the first magnetic blocks 45 on both sides are respectively placed inside the square storage chamber 61; and extended hinge frames 62 movably connected to the hinged sleeve plate 37 on the same side are respectively fixedly mounted at two side edges of an upper surface of the square storage chamber 61.

[0037] The whole square storage chamber 61 is arranged in the space between the two sector-shaped storage chambers 42 and contacts the outer walls of the two sector-shaped storage chambers 42, where the contact with the outer walls of the two sector-shaped storage chambers 42, on the one hand, ensures the stability of vertical movement of the square storage chamber 61 by means of limitations on both sides, and on the other hand, ensures the contact with the first magnetic blocks 45. The plurality of second metal balls 63 correspondingly attracting the first magnetic blocks 45 on both sides are respectively placed inside the square storage chamber 61, so during the vertical movement of the square storage chamber 61 between the two sector-shaped storage chambers 42, the second metal balls 63 inside reciprocate synchronously under the action of the magnetic blocks with different magnetic poles on both sides, to drive the effective flow of a material stored inside the square storage chamber 61.

[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 a particle material to the water-based synthetic cutting fluid. Therefore, it is necessary to store nano-particles in the square storage chamber 61, such as aluminum oxide nano-particles or cerium oxide nano-particles in the prior art. In the water-based synthetic cutting fluid, after subsequent mixing, the nano-particles flow with the fluid and form a uniformly distributed grinding layer on the surface of a workpiece. The size of the nano-particles is much less than that of conventional abrasives, so the nano-particles can leave finer marks on the surface of the workpiece, thereby significantly improving surface finish. For complex shaped workpieces such as wind turbine blades, the high finish is conducive to reducing air resistance and prolonging the service life. In addition, the uniform distribution and gentle polishing characteristics of the nano-particles can effectively avoid surface scratches, cracks, and other problems that may occur in conventional abrasives. However, the nano-particles with extremely small size are prone to settling to the bottom of a container due to gravity or agglomeration. The flow of balls, i.e., the second metal balls 63, stirs the fluid medium and breaks the agglomeration structures between the nano-particles, thereby effectively preventing the settling. Moreover, the movement of the balls also incurs a turbulence effect in the fluid, thereby accelerating the uniform distribution of the nano-particles throughout the fluid. This is crucial for ensuring the concentration of the nano-particles during each use, especially when high-precision machining is required, and the continuous flow of the balls can help maintain the physical and chemical stability of the fluid, thereby extending the service life of the nano-particle suspension.

[0039] The extended hinge frames 62 movably connected to the hinged sleeve plate 37 on the same side are fixedly mounted at the two side edges of the upper surface of the square storage chamber 61, to hinge the second grinding wing plate set 36 on the outer side of the hinged sleeve plate 37. In the semi-finish and finish grinding stages, only the first grinding wing plate set 34 on the outer surface of the first cylindrical sleeve shell 31 needs to be away from an end surface to be ground, the rotation of the spindle rod 51 drives the U-shaped nut pull sleeve 57 to push the square storage chamber 61 vertically back and forth, and the second grinding wing plate set 36 on the outer side of the hinged sleeve plate 37 is ejected outward back and forth due to the movable connection between the extended hinge frames 62 on the outer surface of the square storage chamber 61 and the hinged sleeve plate 37 on the same side, so that the outer section of the second grinding wing plate set 36 is higher than the outer section of the first grinding wing plate set 34. Only when the outer section of the unfolded second grinding wing plate set 36 fits the end surface to be ground, the end surface to be ground can be intermittently ground through the back-and-forth unfolded second grinding wing plate set 36, achieving semi-finish and finish grinding without shutdown.

[0040] Furthermore, in the semi-finish and finish grinding processes, this intermittent grinding method can reduce the accumulation of heat on the surface of the workpiece and the grinding head through periodic interrupt contact, thereby avoiding material deformation or performance degradation caused by high temperatures, reducing the time for continuous contact between the grinding head and the workpiece, reducing the wear rate, significantly extending tool life, especially making the device suitable for complex shaped workpieces such as wind turbine blades, ensuring the consistency and accuracy of the entire surface, and reducing heat affected zones. Therefore, although the single processing time may slightly increase, the overall processing efficiency can be improved by extending the tool life, reducing rework, and optimizing surface quality.

[0041] As shown in FIG. 1 to FIG. 12, the second feeding mechanism 6 further includes an embedded chamber box 64 fixedly mounted at the middle position inside each square storage chamber 61, and an electric extraction pump 65 is respectively fixedly mounted inside the embedded chamber box 64; a suction duct 66 penetrating into the square storage chamber 61 is respectively fixedly mounted on an output end of the electric extraction pump 65, an electric telescopic rod 67 is respectively fixedly mounted at a middle position of an upper surface of the square storage chamber 61, the third grinding wing plate set 68 is respectively fixedly mounted on an output end of the electric telescopic rod 67, and each third grinding wing plate set 68 is of a U-shaped structure when viewed from the side; a spray plate 69 is respectively fixedly mounted on an open concave surface of each third grinding wing plate set 68, and a delivery pipe 610 connected to the output end of the electric extraction pump 65 on the same side is respectively fixedly mounted at a bottom of the spray plate 69.

[0042] The electric extraction pump 65 is a pump capable of electric extraction in the prior art. The embedded chamber box 64 is arranged to separate a storage chamber for mixing the water-based synthetic cutting fluid and the grinding particle material inside the square storage chamber 61. The suction duct 66 on the output end of the electric extraction pump 65 penetrates into the square storage chamber 61, to suck the nano-particles in the square storage chamber 61 into the embedded chamber box 64. Through the trigger communication of a first trigger communication module 7 and a second trigger communication module 8 below, the water-based synthetic cutting fluid in the outer sector-shaped storage chamber 42 can be guided into the embedded chamber box 64 and mixed with the nano-particles in the embedded chamber box 64 to prepare a polishing reagent, The prepared polishing reagent can be delivered from the embedded chamber box 64 to the spray plate 69 through the delivery pipe 610 on the output end of the electric extraction pump 65. The spray plate 69 is a structural plate with a plurality of spray ports.

[0043] The electric telescopic rod 67 is a telescopic rod capable of electric control in the prior art. Through the electric telescopic control of the electric telescopic rod 67, the third grinding wing plate set 68 at the output end can extend outward, so that the outer section of the third grinding wing plate set 68 is higher than the outer section of the second grinding wing plate set 36, to cooperate with the third grinding wing plate set 68 for reciprocating intermittent grinding.

[0044] In addition, compared with conventional pre-mixing in which the performance of a machining fluid degrades because nano-particles may gradually lose dispersibility over time, the real-time mixing of the nano-particles with the water-based synthetic cutting fluid ensures that the machining fluid is always in an optimal state, thereby avoiding performance fluctuations caused by time factors. Moreover, the real-time mixing only prepares an appropriate amount of machining fluid when needed, thereby avoiding unnecessary waste and reducing costs.

[0045] As shown in FIG. 1 to FIG. 12, the air-guiding support module 2 further includes assembly sleeve ports 22 fixedly mounted on both sides of the open end of the U-shaped bracket sleeve 21; transparent circular side cover plates 32 are respectively pressed on both side ends of the first cylindrical sleeve shell 31, the first cylindrical sleeve shell 31 is movably mounted on inner sides of the assembly sleeve ports 22 through the transparent circular side cover plates 32 on both sides, and a second slotted ring 33 is respectively fixedly mounted on the transparent circular side cover plate 32 on each side; a ring-shaped replenishing duct connected to the second slotted ring 33 is respectively fixedly mounted on a side end of the sector-shaped storage chamber 42, and a ring-shaped replenishing duct connected to the second slotted ring 33 on the other side is fixedly mounted on a side end of the square storage chamber 61.

[0046] As shown in FIG. 4 and FIG. 5, the ring-shaped replenishing duct is formed by four connected ring sleeves connected together. The outer side of the ring sleeve structure is connected to the second slotted ring 33. The difference is that the ring-shaped replenishing duct connected to the second slotted ring 33 is fixedly mounted on the side end of the sector-shaped storage chamber 42, and the ring-shaped replenishing duct connected to the second slotted ring 33 on the other side is fixedly mounted on the side end of the square storage chamber 61, that is, the ring-shaped replenishing ducts extending from two storage ends extend from both sides of the first cylindrical sleeve shell 31 respectively.

[0047] As shown in FIG. 1 to FIG. 12, a first slotted ring 25 hermetically connected to the second slotted ring 33 is respectively fixedly mounted on two sides of the open end of the U-shaped bracket sleeve 21, the first slotted ring 25 is provided with a circular liquid guide port 29 connected to the second slotted ring 33, a sealing ring clamping groove 210 is respectively fixedly mounted on the other side of each first slotted ring 25 that is away from the circular liquid guide port 29, and a replenishing interface module 28 is respectively movably fitted on a side of the sealing ring clamping groove 210; the replenishing interface module 28 includes liquid guide shells 281 fixedly mounted on both sides of the U-shaped bracket sleeve 21, a circular edge fitting interface 282 capable of being movably fitted into the sealing ring clamping groove 210 on the same side is respectively fixedly mounted on the liquid guide shell 281, and a side surface of each liquid guide shell 281 is respectively provided with a circular through port 283 connected to the circular liquid guide port 29.

[0048] The sealing ring clamping groove 210 is arranged to movably cover the circular edge fitting interface 282 on the side of the liquid guide shell 281. Because the liquid guide shell 281 is fixed, its outer side can be connected to a corresponding material replenishing tank to replenish materials in real time to the square storage chamber 61 and the sector-shaped storage chamber 42 inside. However, in the working process, its grinding end needs to rotate. Therefore, the sealing movable sleeve for separation ensures stable operation of the replenishing interface.

[0049] As shown in FIG. 1 to FIG. 12, a first trigger communication module 7 is respectively mounted at a middle position on the side of the embedded chamber box 64, and a second trigger communication module 8 is further arranged at a middle position on the side of the sector-shaped storage chamber 42 that is flushed with the first trigger communication module 7; the first trigger communication module 7 includes a first infusion tube 71 that is connected to the side of the embedded chamber box 64 and penetrates the square storage chamber 61, a spherical cavity 72 is fixedly mounted on an extension end of the first infusion tube 71, a through port is formed at a completed axial position of the spherical cavity 72, and a sealing sector-shaped piece set 73 is fixedly mounted in the through port; the second trigger communication module 8 includes a second infusion tube 81 that is connected to the side of the sector-shaped storage chamber 42, the second infusion tube 81 and the first infusion tube 71 are located on a same vertical horizontal line, a side of the second infusion tube 81 that faces the first infusion tube 71 is provided with a spherical round-opening groove 82, a reset rod 83 is respectively fixedly mounted at an inner center position of the second infusion tube 81 through a hollow frame, a reset end of the reset rod 83 extends towards a side of the spherical round-opening groove 82, and a sealing block 84 that can hermetically block the spherical round-opening groove 82 is respectively fixedly mounted on an extension end of the reset rod 83; the sealing block 84 is entirely in a state of penetrating the spherical round-opening groove 82 under the elastic force of the reset rod 83, and a first communication port 85 is formed at an axis position of the sealing block 84 penetrating the spherical round-opening groove 82; two groups of second communication ports 86 are further formed on an outer surface of the first communication port 85, the second communication ports 86 entirely penetrate a side of the sealing block 84, and a trigger ejection rod 87 is further fixedly mounted at an axis position of the first communication port 85.

[0050] The first trigger communication module 7 and the second trigger communication module 8 are arranged on the square storage chamber 61 and the sector-shaped storage chamber 42 respectively. On the vertical horizontal line, the first trigger communication module 7 is controlled to reciprocate and contact the second trigger communication module 8 through the vertical reciprocating movement of the square storage chamber 61, achieving intermittent connection to guide a reagent in the sector-shaped storage chamber 42 into the embedded chamber box 64 of the square storage chamber 61. Details are as follows:

[0051] Firstly, during the vertical reciprocating movement of the square storage chamber 61, the spherical cavity 72 on the outer side of the first infusion tube 71 is squeezed into the spherical round-opening groove 82 on the outer side of the second infusion tube 81. After the spherical cavity 72 is squeezed into the spherical round-opening groove 82, the sealing block 84 is pushed inward, the second communication port 86 originally on the outer side enters the interior of the second infusion tube 81 and guides a reagent inside the second infusion tube 81 to the first communication port 85, the trigger ejection rod 87 in the first communication port 85 pushes the sealing sector-shaped piece set 73 at the axis position of the spherical cavity 72 inward after the spherical cavity 72 is squeezed to a complete fit, and the reagent in the first communication port 85 enters the first infusion tube 71, thereby completing mixed introduction of the reagents;

[0052] Then, during the vertical reciprocating movement of the square storage chamber 61, after the spherical cavity 72 detaches from the spherical round-opening groove 82, the sealing block 84 is pushed out under the reset action of the reset rod 83, and the second communication port 86 comes out to cut off the communication with the interior of the second infusion tube 81.

[0053] As shown in FIG. 1 to FIG. 12, a circular concave cover 23 is further fixedly mounted on the U-shaped bracket sleeve 21 at a position outside the first slotted ring 25, a reserved round port 26 is respectively formed at a center position of the circular concave cover 23 on both side ends of the U-shaped bracket sleeve 21, a round port in communication with the reserved round port 26 is also formed at a center position of the transparent circular side cover plate 32, and a servo motor 27 is fixedly mounted on a side end of an outer surface of the U-shaped bracket sleeve 21 through a bracket; an output end of the servo motor 27 is fixedly connected to the spindle rod 51, two L-shaped gas ducts 24 arranged above and below the first cylindrical sleeve shell 31 are respectively connectedly mounted to an outer side of the circular concave cover 23, and a surface of the L-shaped gas duct 24 is provided with an air outlet facing the first cylindrical sleeve shell 31.

[0054] The air-guiding support module 2 is arranged to further utilize the air duct produced by the cooling fans 52 on the spindle rod 51 during the operation of the device. In the grinding process of the device, dust is produced on the ground end surface. Through the delivery effect of the L-shaped gas ducts 24, the air duct can be further utilized to blow the ground end to offset the influence of some dust.

[0055] The servo motor 27 is designed for servo driving, which drives the rotation of the spindle rod 51. The reserved round port 26, which allows the output end of the servo motor 27 to penetrate and is connected to the spindle rod 51, guides air outward on the other hand. Therefore, the servo motor 27 merely drives the spindle rod 51 to work. The rotation of the first cylindrical sleeve shell 31, i.e., the rotation of the entire grinding sleeve head mechanism 3, is driven by another servo driving mechanism on the bracket. In the prior art, the grinding sleeve shaft is also driven by another servo driving mechanism, as shown in FIG. 1. In the process of driving by another servo driving mechanism, the driven structure needs to rotate at the same frequency as the servo motor 27 through servo adjustment. When driven by the servo motor 27, only the rotation frequency of the servo motor 27 is changed, then a gap difference can be produced between the spindle rod 51 and the first cylindrical sleeve shell 31, and the structure linked with the outer side of the spindle rod 51 operates.

[0056] A using method provided by the present invention is as follows: When the present invention is used, Firstly, the first cylindrical sleeve shell 31 is driven by another servo driving mechanism, the outer first grinding wing plate sets 34 with low-mesh sand belts contact the surface of a workpiece for rough grinding, the servo motor 27 drives the spindle rod, the cooling fans 52 disturb the metal balls in the sector-shaped storage chambers 42 through the magnetic blocks to accelerate the flow of the water-based cutting fluid for heat dissipation, and the L-shaped gas ducts 24 blow away dust; Then, the linkage module 5 drives the bidirectional threaded rods 55 to rotate through the conical gear sets, the square storage chambers 61 are pushed to move vertically, the extended hinge frames 62 eject the second grinding wing plate sets 36 to be higher than the rough grinding surface, and the low-mesh sand belts are switched to medium-mesh sand belts for semi-finish and finish grinding, where the cutting fluid is mixed with the nano-particles into a polishing fluid through magnetic disturbance and the trigger communication modules; Next, the electric telescopic rods 67 push out the third grinding wing plate set 68, and the ultra-fine-mesh polishing surface cooperates with the spray plates 69 for spraying the nano polishing fluid, achieving low thermal damage polishing through high-frequency intermittent contact.

[0057] The present invention encompasses any substitution, modification, equivalent method, and solution made within the essence and scope of the present invention. In order to enable the public to thoroughly understand the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and a person skilled in the art can fully understand the present invention without the description of these details. Furthermore, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, steps, components, and circuits are not described in detail.

[0058] Described above are merely the preferred embodiments of the present invention. It should be pointed out that, for a person of ordinary skill in the technical field, improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also fall within the scope of protection of the present invention.
