Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel technology, specifically a biomimetic textured surface grinding wheel. Background Technology

[0002] Biomimetic textured surface grinding wheels are a new type of grinding tool that mimics the surface structure characteristics of natural organisms (such as cacti, snake bellies, and tree frog toes). They create special textures on the grinding wheel surface, such as micropores, flow-guiding grooves, scale-like protrusions, or regular hexagonal grooves. The preparation methods vary depending on the biomimetic prototype, and may include processes such as water-guided laser processing, 3D printing deposition, template coating and curing, or laser fabrication. Some may also require optimization techniques such as solid lubricant embedding. The core advantage lies in optimizing chip removal performance, improving grinding fluid wettability, and reducing abrasive clogging and passivation through textured structure, thereby achieving the technical goals of improved grinding efficiency, extended grinding wheel life, and enhanced surface quality and stability.

[0003] In existing biomimetic textured surface grinding wheels, while the micropores, flow grooves, and scale-like protrusions on the wheel surface can optimize chip removal and lubrication performance during actual grinding operations, grinding chips tend to accumulate in the gaps between the textures due to high-speed impact and adsorption under high-load grinding scenarios. To ensure the continued effectiveness of the biomimetic function, it is necessary to regularly and accurately inspect the wear degree and structural integrity of the texture using professional testing equipment. When replacing the grinding wheel, because the requirements for installation coaxiality, end face runout accuracy, and dynamic balance performance of biomimetic textured grinding wheels are much higher than those of traditional grinding wheels, multiple calibrations and adjustments are required. In cases where biomimetic textured surface grinding wheels need to be frequently disassembled and assembled, the traditional bolt connection structure is time-consuming and labor-intensive, making the overall operation process more cumbersome compared to traditional grinding wheels. Utility Model Content

[0004] To address the shortcomings of existing technologies and solve the problems of needing to regularly use professional testing equipment to accurately inspect the wear degree and structural integrity of the texture, and the fact that biomimetic textured grinding wheels have much higher requirements for installation coaxiality, end face runout accuracy and dynamic balance performance than traditional grinding wheels when replacing grinding wheels, requiring multiple calibrations and adjustments, and that the traditional bolt connection structure is time-consuming and labor-intensive when biomimetic textured surface grinding wheels need to be frequently disassembled and assembled, resulting in a more cumbersome overall operation process compared to traditional grinding wheels, this utility model proposes a biomimetic textured surface grinding wheel.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a biomimetic textured surface grinding wheel of this utility model, comprising:

[0006] A grinding wheel disc, wherein a grinding wheel ring is fitted on the surface of the grinding wheel disc, and the grinding wheel ring is provided with a biomimetic fish scale pattern, which is used for grinding.

[0007] A connecting assembly is disposed in the middle of the grinding wheel. The connecting assembly includes a first rotating cavity formed in the middle of the grinding wheel, in which a rotating ring rotates to adjust the connection state between the grinding wheel and the grinding wheel ring. A connecting ring is fixedly connected to the outer arc surface of the first rotating cavity. A second rotating cavity is formed inside the grinding wheel, and the first rotating cavity and the second rotating cavity are connected. A rotating disk is rotatably connected to the second rotating cavity. The outer arc surface of the connecting ring is fixedly connected to the rotating disk. Eight connecting seats are equidistantly arranged inside the rotating disk. Eight sliding grooves are equidistantly formed on the outer arc surface of the grinding wheel, and all eight connecting seats are slidably connected to the sliding grooves. Eight positioning grooves are equidistantly formed on the inner arc surface of the grinding wheel ring, and all eight connecting seats are slidably connected to the positioning grooves.

[0008] Preferably, the rotating disk has sixteen symmetrical sliding grooves, with each pair of sliding grooves forming a group. Each group of sliding grooves has a sliding shaft slidably connected to it, and all eight sliding shafts are fixedly connected to the connecting seat.

[0009] Preferably, each of the eight connecting seats is provided with a sliding groove, an extrusion groove and a telescopic groove. The sliding groove is connected to the extrusion groove, the extrusion groove is connected to the telescopic groove, a return spring is fixedly installed in the telescopic groove, a sliding pin is slidably connected in the sliding groove, an extrusion block is slidably connected in the extrusion groove, and the sliding pin is fixedly connected to the extrusion block.

[0010] Preferably, four rotating plates are equidistantly rotatably connected within the telescopic groove, and each of the four rotating plates has a silicone pad on the side away from the return spring.

[0011] Preferably, each of the eight positioning slots is fixedly connected with a semi-circular block, and the semi-circular block and the sliding pin form a pressing fit.

[0012] Preferably, a fixing ring is fixedly connected to one side of the grinding wheel, and two fixing bolts are symmetrically threaded onto the fixing ring. Four positioning holes are symmetrically opened on the rotating ring, and two positioning holes with opposite openings form a group. All four positioning holes are threadedly connected to the fixing bolts.

[0013] Preferably, the grinding wheel ring is fixedly connected with four fixing bolts at equal intervals.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The biomimetic textured surface grinding wheel of this utility model, by setting a detachable grinding wheel ring structure, allows the grinding wheel ring with biomimetic fish scale pattern to be quickly separated from the grinding wheel disc. When the texture is clogged, worn, or needs cleaning, there is no need to replace the entire grinding wheel; only the grinding wheel ring needs to be removed for repair or replacement. This reduces the cost of use and significantly improves maintenance efficiency, effectively solving the problem of difficult maintenance caused by the integral structure of traditional biomimetic grinding wheels.

[0016] 2. The biomimetic textured surface grinding wheel of this utility model is locked to the grinding wheel ring and the grinding wheel disk through a linkage mechanism consisting of a rotating ring, a rotating disk, a connecting seat, and a sliding groove. During the locking process, a semi-circular block is used to squeeze the sliding pin, driving the rotating plate to open and pressing the silicone gasket against the inner wall of the positioning groove. This design not only enhances the fit and friction of the connection parts, but also effectively fills the assembly gap, preventing the grinding wheel ring from loosening or shifting during high-speed rotation, and ensuring the safety and accuracy of the grinding process.

[0017] 3. The biomimetic textured surface grinding wheel of this utility model has multiple fixing bolts on the grinding wheel ring, on which a weight plate can be added and fixed with a nut, which facilitates flexible adjustment of the mass distribution according to the actual rotation state. This design simplifies the dynamic balancing correction process of the biomimetic grinding wheel after installation, avoids vibration problems caused by the asymmetry of the biomimetic structure, and improves the stability of equipment operation and the quality of the processed surface.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 As shown, this embodiment discloses a biomimetic textured surface grinding wheel, including a grinding wheel disk 100 and a connecting component 200, with the connecting component 200 disposed in the middle of the grinding wheel disk 100.

[0031] Furthermore, while existing biomimetic textured surface grinding wheels offer significant advantages in chip removal, heat dissipation, and machining quality, their use also incurs additional maintenance burdens. Due to the ease with which the microstructure is clogged by grinding debris and the potential for damage to the texture using traditional dressing methods, frequent fine cleaning or non-contact dressing is required. To ensure the effectiveness of the biomimetic function, the wear status of the texture must be checked periodically using specialized equipment. When replacing the grinding wheel, the high-precision installation, dynamic balancing requirements, and possible system recalibration make the operation more time-consuming and labor-intensive than with traditional grinding wheels.

[0032] During use, the biomimetic fish scale pattern 111 is set on the outer surface of the grinding wheel ring 110. When maintaining the biomimetic fish scale pattern 111, first unscrew the fixing bolt 281 to release the fixing ring 280 from the constraint of the rotating ring 220. Then, rotate the rotating ring 220 counterclockwise. This, through the connecting ring 221, drives the rotating disk 240 to rotate counterclockwise synchronously. The rotation of the rotating disk 240 drives the sliding groove 241 to move, thereby causing the sliding groove 231 in the connecting seat 250 to disengage from the positioning groove 120. At this point, the grinding wheel ring 110 can be removed from the outer arc surface of the grinding wheel disk 100 for cleaning or repairing the biomimetic fish scale pattern 111. After maintenance, the grinding wheel ring 110 is re-set onto the outer arc surface of the grinding wheel disk 100, and the rotating ring 220 is rotated clockwise. This action is transmitted to the rotating disk 240 via the connecting ring 221, causing it to rotate clockwise and pushing the sliding groove 241 towards the connecting seat 250. The sliding groove 231 slides back into the positioning groove 120. During this process, the sliding pin 270 contacts the semi-circular block 121 in the positioning groove 120, and under its squeezing action, pushes the squeezing block 271 into the telescopic groove 253. At the same time, the squeezing block 271 cooperates with the inclined surface on the rotating plate 260, driving the rotating plate 260 to open outward with its rotational connection point with the connecting seat 250 as the fulcrum, thereby tightly pressing the silicone gasket 261 into the positioning groove 120. On the inner wall, the fit and friction between the connecting seat 250 and the positioning groove 120 are significantly enhanced, effectively preventing the grinding wheel ring 110 from loosening when the grinding wheel disc 100 rotates at high speed. This allows for the quick removal of the grinding wheel ring 110 from the grinding wheel disc 100, facilitating the separate maintenance of the bionic fish scale pattern 111 on the grinding wheel ring 110. Furthermore, when the surface of the bionic fish scale pattern 111 is severely worn, the grinding wheel ring 110 can be directly replaced, while retaining the main body of the grinding wheel disc 100.

[0033] like Figure 1 As shown, a grinding wheel ring 110 is fitted on the surface of the grinding wheel disc 100, and the grinding wheel ring 110 is provided with a biomimetic fish scale pattern 111.

[0034] like Figure 2 and Figure 3As shown, the connecting assembly 200 includes a rotating cavity 210 located in the middle of the grinding wheel 100. A rotating ring 220 is rotatably connected inside the rotating cavity 210 for adjusting the connection between the grinding wheel 100 and the grinding wheel ring 110. A connecting ring 221 is fixedly connected to the outer arc surface of the rotating cavity 210. A rotating cavity 230 is located inside the grinding wheel 100, and the rotating cavity 210 and the rotating cavity 230 are connected. A rotating disk 240 is rotatably connected inside the rotating cavity 230. The outer arc surface of the connecting ring 221 is fixedly connected to the rotating disk 240. Eight connecting seats 250 are equidistantly arranged inside the rotating disk 240. Eight sliding grooves 231 are equidistantly arranged on the outer arc surface of the grinding wheel 100, and the eight connecting seats 250 are slidably connected to the sliding grooves 231. Eight positioning grooves 120 are equidistantly arranged on the inner arc surface of the grinding wheel ring 110, and the eight connecting seats 250 are slidably connected to the positioning grooves 120.

[0035] like Figure 3 and Figure 4 As shown, sixteen sliding grooves 241 are symmetrically provided on the rotating disk 240. The sliding grooves 241 are inclined. The sliding grooves 241 are arranged in pairs. Each pair of sliding grooves 241 is slidably connected to a sliding shaft 242. All eight sliding shafts 242 are fixedly connected to the connecting seat 250. When the rotating disk 240 rotates, the sliding grooves 241 squeeze the sliding shafts 242, thereby driving the connecting seat 250 to move.

[0036] like Figure 4 As shown, each of the eight connecting seats 250 has a sliding groove 251, a pressing groove 252, and a telescopic groove 253. The sliding groove 251 is connected to the pressing groove 252, and the pressing groove 252 is connected to the telescopic groove 253. A return spring 254 is fixedly installed in the telescopic groove 253. A sliding pin 270 is slidably connected in the sliding groove 251. A pressing block 271 is slidably connected in the pressing groove 252. The sliding pin 270 is fixedly connected to the pressing block 271. Four rotating plates 260 are equidistantly rotatably connected in the telescopic groove 253. The rotating plate 260 has an inclined surface on the side near the extrusion groove 252. The extrusion block 271 can push the inclined surface to make the rotating plate 260 rotate. A torsion spring is provided at the rotation point of the rotating plate 260 and the telescopic groove 253. When the rotating plate 260 is not subjected to external extrusion, it will retract back into the telescopic groove 253 under the action of the torsion spring. A silicone gasket 261 is provided on the side of each of the four rotating plates 260 away from the return spring 254. The silicone gasket 261 can fill the gap between the connecting seat 250 and the positioning groove 120, making the connection tighter.

[0037] like Figure 5As shown, each of the eight positioning slots 120 is fixedly connected with a semi-circular block 121. The diameter of the semi-circular block 121 is the same as that of the sliding slot 251. The semi-circular block 121 and the sliding pin 270 form a pressing fit. After the connecting seat 250 is fully inserted into the positioning slot 120, the semi-circular block 121 will squeeze into the sliding slot 251, thereby pushing the sliding pin 270 to slide.

[0038] like Figure 6 and Figure 7 As shown, a fixing ring 280 is fixedly connected to one side of the grinding wheel 100. Two fixing bolts 281 are symmetrically threaded onto the fixing ring 280. Four positioning holes 222 are symmetrically opened on the rotating ring 220. The two positioning holes 222 with opposite openings form a group. The distance between the two groups of positioning holes 222 is the same as the length of a single stroke of the sliding groove 241 that can drive the sliding shaft 242 to slide. Thus, after the rotating wheel 240, the sliding groove 241 and the sliding shaft 242 drive the connecting seat 250 to extend into or slide out of the rotating cavity 210, there is always one group of positioning holes 222 aligned with the fixing bolts 281. All four positioning holes 222 are threadedly connected to the fixing bolts 281.

[0039] like Figure 2 As shown, four fixing bolts 290 are fixedly connected at equal intervals on the grinding wheel ring 110. A counterweight can be added to the fixing bolts 290. After the counterweight is added, it can be fixed to the fixing bolts 290 with nuts, which facilitates the dynamic balancing of the biomimetic textured surface grinding wheel.
