Description

Technical Field

[0001] This invention relates to the field of grinding wheels, and more particularly to a robust composite structure for a diamond elastic grinding wheel. Background Technology

[0002] Chinese Patent 2026104445204 discloses a diamond grinding wheel based on additive manufacturing, which mainly includes: diamond grinding discs, a skeleton, and a grinding wheel base. The skeleton is a non-working layer ring structure manufactured by additive manufacturing process. The skeleton is fixedly installed on the end face of the grinding wheel base. Multiple diamond grinding discs are circumferentially spaced and fixedly installed on the skeleton. The skeleton is provided with a variety of functional structures, thereby realizing a multi-functional composite structure grinding wheel with optimized performance.

[0003] With the expansion of the application of flexible grinding wheels, existing technologies have further introduced flexible support plates (such as 301 spring steel support plates). Existing technologies mainly rely on the properties of the skeleton material (mainly thermoplastic polymers or materials) to install and support the diamond grinding disc and the flexible support plate. The strength and reliability of the skeleton are difficult to meet the harsh working conditions such as heavy-duty grinding, intermittent grinding, and dry grinding. Problems such as skeleton breakage, loosening and flying off of the grinding disc, and stress concentration and breakage of the grinding disc are prone to occur, which will cause the shape of the grinding surface to deviate from the normal state, thus making the grinding effect worse. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a secure and robust composite structure for diamond elastic grinding wheel discs, so as to solve the above-mentioned problem.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a security and reinforcement composite structure for a diamond elastic grinding wheel, comprising: a grinding wheel, a frame and a grinding wheel base, wherein the frame is fixedly installed on the grinding wheel base, and a plurality of grinding wheels are circumferentially spaced and fixedly installed on the frame, and the frame is provided with steel wires in the inner circumferential direction for coupling the frame and the grinding wheels.

[0006] The beneficial effects of this invention are as follows: The steel wires inside the skeleton facilitate the formation of an integrated structure combining a metal mesh and polymer materials within the skeleton. This structure, similar to reinforced concrete, increases the strength of the skeleton, preventing skeleton breakage and the grinding disc from loosening and flying off within the skeleton. The steel wires couple the skeleton and the grinding disc, reducing positional changes during grinding and ensuring more stable stress distribution, thus lowering the risk of stress concentration and breakage. Furthermore, this invention helps maintain the shape of the grinding surface in a normal state, thereby ensuring optimal grinding performance.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, one end of the grinding disc is fixedly connected to the grinding wheel base, and a grinding disc mounting hole is provided on the grinding disc. The grinding disc mounting hole is a circumferential through hole, and multiple steel wires pass through multiple grinding disc mounting holes respectively. The steel wires are connected to the grinding disc mounting holes with a clearance fit.

[0009] The beneficial effects of adopting the above-mentioned further solution are: the clearance fit between the steel wire and the grinding disc mounting hole helps to limit the displacement of the grinding disc within the frame, preventing the grinding disc from exceeding the allowable value due to excessive displacement within the frame, thus reducing the risk of stress concentration fracture; in addition, the steel wire can also prevent the grinding disc from loosening and flying off within the frame due to excessive displacement.

[0010] Furthermore, a grinding disc mounting groove is provided at one end of the grinding disc. The grinding disc mounting groove is a circumferential through groove. Multiple steel wires pass through multiple grinding disc mounting grooves respectively, and the steel wires are connected to the grinding disc mounting grooves with a clearance fit.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the steel wire and the grinding disc mounting groove are connected with a clearance fit, which is conducive to supporting the grinding disc with a stronger steel wire, dispersing the external force on the grinding disc during grinding, and reducing the risk of the grinding disc and the skeleton loosening and flying off due to fatigue deformation of the skeleton material.

[0012] Furthermore, the grinding disc is spaced apart from the grinding wheel base, and one end of the grinding disc is provided with a grinding disc mounting hole. The grinding disc mounting hole is a circumferential through hole, and multiple steel wires pass through multiple grinding disc mounting holes respectively. The steel wires are connected to the grinding disc mounting holes with a clearance fit.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the clearance fit between the steel wire and the grinding disc mounting hole helps to limit the displacement of the grinding disc within the frame, preventing the grinding disc from exceeding the allowable value due to excessive displacement within the frame, thus reducing the risk of stress concentration fracture; in addition, the steel wire can also prevent the grinding disc from loosening and flying off within the frame due to excessive displacement.

[0014] Furthermore, it also includes support plates, a plurality of support plates are circumferentially spaced and fixedly installed on the frame, the plurality of support plates correspond to the plurality of grinding plates respectively, and are used to provide elastic support for the grinding plates, one end of the support plate being fixedly connected to the grinding wheel base.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the support plate helps to provide elastic support for the grinding plate.

[0016] Furthermore, one end of the support piece is provided with a support piece placement hole, which is a circumferential through hole. Multiple steel wires pass through multiple support piece placement holes respectively, and the steel wires are connected to the support piece placement holes with a clearance fit.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the steel wire and the support plate mounting hole are connected with a clearance fit, which helps to limit the displacement of the support plate in the frame, and avoids the point contact range between the support plate and the grinding wheel base being too large due to excessive displacement in the frame, thus exceeding the allowable value and reducing the risk of stress concentration fracture; in addition, the steel wire can also prevent the support plate from loosening and flying off in the frame due to excessive displacement.

[0018] Furthermore, the skeleton has multiple spaced cavities in the circumferential direction, and the support plate and the grinding plate are attached and disposed in the same cavity, or the support plate and the grinding plate are spaced apart and disposed in two circumferentially adjacent cavities.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the cavity helps to provide support for fixing the support plate and grinding plate on the skeleton.

[0020] Furthermore, both the support plate and the grinding plate are inclined backward along the rotation direction of the grinding wheel.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that it helps to make the grinding disc substrate on the grinding disc provide support for the diamond.

[0022] Furthermore, the steel wire is made of stainless steel, the steel wire is circular, and the steel wire is single-stranded or multi-stranded.

[0023] The beneficial effects of adopting the above-mentioned further solutions are: it helps prevent steel wire corrosion and breakage, and increases the strength of the steel wire.

[0024] Furthermore, the skeleton is a ring structure obtained through additive manufacturing.

[0025] The beneficial effect of adopting the above-mentioned further solutions is that it helps to improve the ease of assembly of grinding discs and support discs. Attached Figure Description

[0029] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] Example 1.

[0031] like Figure 1 As shown, this embodiment provides a security and reinforcement composite structure for a diamond elastic grinding wheel, including: a grinding wheel 1, a frame 2 and a grinding wheel base 3. The frame 2 is fixedly installed on the grinding wheel base 3. A plurality of grinding wheels 1 are circumferentially spaced and fixedly installed on the frame 2. The frame 2 is provided with steel wires 4 in the inner circumferential direction for coupling the frame 2 and the grinding wheels 1.

[0032] Preferred, such as Figure 1As shown, one end of the grinding disc 1 is fixedly connected to the grinding wheel base 3. The grinding disc 1 has a grinding disc mounting hole 12, which is a circumferential through hole. Multiple steel wires 4 pass through multiple grinding disc mounting holes 12 respectively, and the steel wires 4 are connected to the grinding disc mounting holes 12 with clearance fit.

[0033] Preferably, the skeleton 2 is a ring structure obtained by additive manufacturing process, and its material is an elastic polymer material or an elastic composite polymer material.

[0034] Preferably, the steel wire 4 is made of stainless steel, which helps to prevent corrosion and breakage of the steel wire. The steel wire 4 is circular and is a single strand.

[0035] Preferably, the grinding disc 1 is tilted backward along the rotation direction of the grinding wheel.

[0036] It should be noted that in this embodiment, the non-grinding end of the grinding disc 1 is fixedly connected to the grinding wheel base 3, the non-grinding end of the grinding disc 1 is provided with a grinding disc mounting hole 12, and the non-grinding end of the grinding disc 1 is disposed in the cavity 21 opened on the skeleton 2. In this embodiment, since the grinding disc 1 is tilted backward along the rotation direction of the grinding wheel, the slope of the groove 21 on the frame 2 needs to match the slope of the grinding disc 1. In addition, the grinding disc 1 is fixedly connected to the grinding wheel base 3 through anti-flying structures such as dovetail grooves and dovetail blocks. However, in the actual processing and assembly process, it is difficult for the anti-flying structure on the grinding wheel base 3 to completely match the anti-flying structure on the grinding disc 1. After the anti-flying structure on the grinding wheel base 3 and the anti-flying structure on the grinding disc 1 are assembled, the contact surfaces of the two are not completely fitted. Instead, point contact, line contact, and surface contact may all exist. Therefore, if the displacement of the grinding disc 1 in the frame 2 is too large, it may cause the point contact range between the grinding disc 1 and the grinding wheel base 3 to be too large and exceed the allowable value. Too many point contacts will cause the stress between the grinding disc 1 and the grinding wheel base 3 to be more concentrated, eventually leading to the breakage of the grinding disc 1. Therefore, in this embodiment, the role of "coupling" is reflected in the fact that the steel wire 4 limits the displacement of the grinding disc 1 within the skeleton 2 (the allowable displacement is the gap between the steel wire 4 and the grinding disc mounting hole 12), preventing the grinding disc 1 from having an excessively large point contact range with the grinding wheel base 3 due to excessive displacement within the skeleton 2, thus reducing the risk of stress concentration fracture. In addition, the steel wire 4 can also prevent the grinding disc 1 from loosening and flying off within the skeleton 2 due to excessive displacement. Furthermore, the steel wire 4 helps to form an integrated structure of metal mesh and polymer material inside the skeleton 2, which is similar to a reinforced concrete structure, thus increasing the strength of the skeleton 2 and preventing it from breaking. In this embodiment, the grinding disc 1 is a rigid diamond grinding disc, and there is no elastic support disc 5 in this embodiment. The elastic grinding of the grinding wheel is achieved by the material of the skeleton 2. If the grinding wheel is a cup-shaped grinding wheel, the skeleton 2 is fixedly installed on the end face of the grinding wheel base 3, and the plurality of grinding disc mounting holes 12 are arranged radially on the grinding disc 1 at intervals. If the grinding wheel is a peripheral grinding wheel, the frame 2 is fixedly installed on the outer peripheral surface of the grinding wheel base 3, and the plurality of grinding disc mounting holes 12 are spaced apart on the grinding disc 1 along the axial direction.

[0037] The beneficial effects of this embodiment are as follows: The steel wires inside the skeleton facilitate the formation of an integrated structure combining a metal mesh and polymer materials within the skeleton. This structure, similar to reinforced concrete, increases the skeleton's strength, preventing skeleton breakage and the grinding disc from loosening and flying off within the skeleton. The steel wires couple the skeleton and the grinding disc, reducing positional changes during grinding and ensuring more stable stress distribution, thus lowering the risk of stress concentration and breakage. Furthermore, this embodiment helps maintain the shape of the grinding surface in a normal state, thereby ensuring the grinding effect.

[0038] Example 2.

[0039] like Figure 2 and Figure 3 As shown, this embodiment provides a security and reinforcement composite structure for a diamond elastic grinding wheel, including: a grinding wheel 1, a frame 2 and a grinding wheel base 3. The frame 2 is fixedly installed on the grinding wheel base 3. A plurality of grinding wheels 1 are circumferentially spaced and fixedly installed on the frame 2. The frame 2 is provided with steel wires 4 in the inner circumferential direction for coupling the frame 2 and the grinding wheels 1.

[0040] Preferably, one end of the grinding disc 1 is provided with a grinding disc mounting groove 11, which is a circumferential through groove. Multiple steel wires 4 pass through multiple grinding disc mounting grooves 11 respectively, and the steel wires 4 are connected to the grinding disc mounting grooves 11 with a clearance fit.

[0041] Preferably, the steel wire 4 is made of stainless steel, which helps to prevent corrosion and breakage of the steel wire and makes the steel wire 4 stronger. The steel wire 4 is circular and has multiple strands.

[0042] Preferably, the skeleton 2 is a ring structure obtained by additive manufacturing process, and its material is an elastic polymer material or an elastic composite polymer material.

[0043] Preferably, the grinding disc 1 is tilted backward along the rotation direction of the grinding wheel.

[0044] It should be noted that in this embodiment, a grinding disc mounting groove 11 is provided at one end of the grinding disc 1 located at the non-grinding end; If the grinding wheel is a cup-shaped grinding wheel, the skeleton 2 is fixedly installed on the end face of the grinding wheel base 3, and a plurality of grinding disc mounting slots 11 are arranged radially on the grinding disc 1 at intervals. If the grinding wheel is a peripheral grinding wheel, the frame 2 is fixedly installed on the outer peripheral surface of the grinding wheel base 3, and the plurality of grinding disc mounting slots 11 are spaced apart on the grinding disc 1 along the axial direction; In this embodiment, the grinding disc 1 is a rigid diamond grinding disc, and there is no elastic support disc 5 in this embodiment. The elastic grinding of the grinding wheel is achieved by the material of the skeleton 2. In this embodiment, since the grinding disc 1 is completely set inside the cavity 21 opened on the skeleton 2, and the skeleton 2 is an elastic polymer material or elastic composite polymer material manufactured by additive manufacturing process, the strength of the skeleton 2 is smaller than that of the grinding disc 1. Therefore, when the grinding disc 1 is subjected to grinding force, it will squeeze or even cut the skeleton 2 with relatively small strength, causing the grinding disc 1 to loosen and fly away in the cavity 21. Therefore, in this embodiment, the "coupling" function is manifested in supporting the grinding disc 1 with the stronger steel wire 4, decomposing the external force experienced by the grinding disc 1 during grinding. In addition, since the steel wire 4 is circular, the grinding disc 1 is only locally stressed at a certain point in time on the grinding end face, not all grinding discs 1 on the grinding wheel are stressed. It is equivalent to only part of the steel wire 4 being subjected to the external force transmitted by the grinding disc 1, while the other part of the steel wire 4 supports the grinding disc 1, preventing the grinding disc 1 from pressing the entire steel wire 4 together to cut the skeleton 2, reducing the risk of the grinding disc 1 loosening and flying off from the skeleton 2 due to fatigue deformation of the skeleton 2 material. At the same time, since the steel wire 4 is multi-stranded and sits on the skeleton 2, the skeleton 2 material has a certain degree of elasticity. The above structure can buffer the force on the grinding disc 1 and provide the necessary non-rigid support force, reducing the risk of fatigue strength fracture of the skeleton 2 and stress concentration fracture of the grinding disc 1. In addition, the steel wire 4 is conducive to forming an integrated structure of metal mesh and polymer material mixed inside the skeleton 2. This structure is similar to a reinforced concrete structure, which helps to increase the strength of the skeleton 2 and prevent the skeleton 2 from breaking.

[0045] The beneficial effects of this embodiment are as follows: The steel wires inside the skeleton facilitate the formation of an integrated structure combining a metal mesh and polymer materials within the skeleton. This structure, similar to reinforced concrete, increases the skeleton's strength, preventing skeleton breakage and the grinding disc from loosening and flying off within the skeleton. The steel wires couple the skeleton and the grinding disc, reducing positional changes during grinding and ensuring more stable stress distribution, thus lowering the risk of stress concentration and breakage. Furthermore, this embodiment helps maintain the shape of the grinding surface in a normal state, thereby ensuring the grinding effect.

[0046] Example 3.

[0047] like Figures 4 to 7 As shown, based on Embodiment 2, this embodiment also includes a support plate 5. Multiple support plates 5 are circumferentially spaced and fixedly installed on the skeleton 2. The multiple support plates 5 correspond to multiple grinding plates 1 respectively, and are used to provide elastic support for the grinding plates 1. One end of the support plate 5 is fixedly connected to the grinding wheel base 3.

[0048] Preferably, one end of the support piece 5 is provided with a support piece placement hole 51, which is a circumferential through hole. Multiple steel wires 4 pass through multiple support piece placement holes 51 respectively, and the steel wires 4 are connected to the support piece placement holes 51 with a clearance fit.

[0049] Preferably, the skeleton 2 has a plurality of spaced-apart cavities 21 circumferentially arranged, such as... Figure 4 and Figure 5 As shown, the support plate 5 and the grinding plate 1 are attached and disposed in the same cavity 21, or as... Figure 6 and Figure 7 As shown, the support plate 5 and the grinding plate 1 are spaced apart and respectively disposed in two circumferentially adjacent cavities 21.

[0050] The steel wire 4 is used to couple the skeleton 2, the grinding disc 1, and the support disc 5.

[0051] Preferably, the support plate 5 is inclined backward along the rotation direction of the grinding wheel.

[0052] It should be noted that in this embodiment, the support plate 5 is an elastic support plate, and the preferred material of the support plate 5 is spring steel sheet (such as 301 stainless steel, 65Mn, etc.). The end of the support plate 5 located at the non-grinding end is fixedly connected to the grinding wheel base 3, and a support plate mounting hole 51 is opened at the end of the support plate 5 located at the non-grinding end. If the grinding wheel is a cup-shaped grinding wheel, the skeleton 2 is fixedly installed on the end face of the grinding wheel base 3, and a plurality of support plate mounting holes 51 are arranged radially on the support plate 5 at intervals. If the grinding wheel is a peripheral grinding wheel, the skeleton 2 is fixedly installed on the outer peripheral surface of the grinding wheel base 3, and the plurality of support plate mounting holes 51 are spaced apart on the support plate 5 along the axial direction; In this embodiment, the grinding disc 1 is a rigid diamond grinding disc, and the elastic grinding of the grinding wheel is achieved through the material of the skeleton 2 and the support plate 5. Since this embodiment adds a support piece 5 compared to embodiment two, and the support piece 5 may also break due to stress concentration and detach from the skeleton 2, the "coupling" function in this embodiment, in addition to being the same as in embodiment two, is also reflected in the fact that the displacement of the support piece 5 within the skeleton 2 is limited by the steel wire 4 (the allowable displacement is the gap between the steel wire 4 and the support piece mounting hole 51). This prevents the support piece 5 from having an excessively large point contact range with the grinding wheel base 3 due to excessive displacement within the skeleton 2, thus reducing the risk of stress concentration and breakage. In addition, the steel wire 4 can also prevent the support piece 5 from loosening and detaching from the skeleton 2 due to excessive displacement within the skeleton 2.

[0053] The beneficial effects of this embodiment are as follows: The steel wires inside the skeleton facilitate the formation of an integrated structure combining a metal mesh and polymer materials within the skeleton. This structure, similar to reinforced concrete, increases the skeleton's strength, preventing skeleton breakage and the loosening and detachment of the grinding discs and support plates within the skeleton. The steel wires couple the skeleton, grinding discs, and support plates, reducing positional changes in the grinding discs during grinding, resulting in more stable stress distribution and lowering the risk of stress concentration and fracture. Furthermore, this embodiment helps maintain the shape of the grinding surface in a normal state, thereby ensuring the grinding effect.

[0054] Example 4.

[0055] like Figures 8 to 11 As shown, this embodiment provides a security and reinforcement composite structure for a diamond elastic grinding wheel, including: a grinding wheel 1, a frame 2 and a grinding wheel base 3. The frame 2 is fixedly installed on the grinding wheel base 3. A plurality of grinding wheels 1 are circumferentially spaced and fixedly installed on the frame 2. The frame 2 is provided with steel wires 4 in the inner circumferential direction.

[0056] Preferably, the grinding disc 1 is spaced apart from the grinding wheel base 3, and one end of the grinding disc 1 is provided with a grinding disc mounting hole 12. The grinding disc mounting hole 12 is a circumferential through hole, and a plurality of steel wires 4 pass through a plurality of grinding disc mounting holes 12 respectively. The steel wires 4 are connected to the grinding disc mounting holes 12 with a clearance fit.

[0057] This embodiment also includes support plates 5, a plurality of support plates 5 are circumferentially spaced and fixedly installed on the skeleton 2, the plurality of support plates 5 correspond to the plurality of grinding plates 1 respectively, and are used to provide elastic support for the grinding plates 1, one end of the support plate 5 is fixedly connected to the grinding wheel base 3.

[0058] Preferably, one end of the support piece 5 is provided with a support piece placement hole 51, which is a circumferential through hole. Multiple steel wires 4 pass through multiple support piece placement holes 51 respectively, and the steel wires 4 are connected to the support piece placement holes 51 with a clearance fit.

[0059] Preferably, the skeleton 2 has a plurality of spaced-apart cavities 21 circumferentially arranged, such as... Figure 8 and Figure 9 As shown, the support plate 5 and the grinding plate 1 are attached and disposed in the same cavity 21, or as... Figure 10 and Figure 11 As shown, the support plate 5 and the grinding plate 1 are spaced apart and respectively disposed in two circumferentially adjacent cavities 21.

[0060] The steel wire 4 is used to couple the skeleton 2, the grinding disc 1, and the support disc 5.

[0061] Preferably, the skeleton 2 is a ring structure obtained by additive manufacturing process, and its material is an elastic polymer material or an elastic composite polymer material.

[0062] Preferably, the steel wire 4 is made of stainless steel, which helps to prevent the steel wire from corroding and breaking, and the steel wire 4 is circular.

[0063] Preferably, both the grinding disc 1 and the support disc 5 are inclined backward along the rotation direction of the grinding wheel.

[0064] It should be noted that in this embodiment, the support plate 5 is an elastic support plate, and the preferred material of the support plate 5 is spring steel sheet (such as 301 stainless steel, 65Mn, etc.). The end of the support plate 5 located at the non-grinding end is fixedly connected to the grinding wheel base 3, and a support plate mounting hole 51 is opened at the end of the support plate 5 located at the non-grinding end. If the grinding wheel is a cup-shaped grinding wheel, the skeleton 2 is fixedly installed on the end face of the grinding wheel base 3, and a plurality of support plate mounting holes 51 are arranged radially at intervals on the support plate 5, and a plurality of grinding plate mounting holes 12 are arranged radially at intervals on the grinding plate 1. If the grinding wheel is a peripheral grinding wheel, the skeleton 2 is fixedly installed on the outer peripheral surface of the grinding wheel base 3, and a plurality of support plate mounting holes 51 are spaced apart on the support plate 5 along the axial direction, and a plurality of grinding plate mounting holes 12 are spaced apart on the grinding plate 1 along the axial direction. Regardless of whether it is a cup-shaped grinding wheel or a peripheral grinding wheel, the number of grinding disc mounting holes 12 on a grinding disc 1, the number of support plate mounting holes 51 on a support plate 5, and the number of steel wires 4 are all the same. For a single grinding disc 1 and a single support plate 5, multiple steel wires 4 pass through multiple grinding disc mounting holes 12 on a single grinding disc 1 and multiple support plate mounting holes 51 on a single support plate 5, respectively. For multiple grinding discs 1 and multiple support plates 5, after passing through a certain grinding disc mounting hole 12 on a single grinding disc 1 and a certain support plate mounting hole 51 on a single support plate 5, the steel wire 4 passes through the corresponding grinding disc mounting hole 12 on another adjacent grinding disc 1 and the corresponding support plate mounting hole 51 on another support plate 5 in the circumferential direction, until the steel wire 4 passes through all the grinding discs 1 and all the support plates 5. In this embodiment, the grinding disc 1 is a rigid diamond grinding disc, and the elastic grinding of the grinding wheel is achieved through the material of the skeleton 2 and the support plate 5. Compared to Embodiment 1, this embodiment adds a support plate 5 and replaces the fixed connection between the grinding disc 1 and the grinding wheel base 3 with a fixed connection between the support plate 5 and the grinding wheel base 3. Therefore, the "coupling" function in this embodiment, in addition to being the same as in Embodiment 1 where "the displacement of the grinding disc 1 within the frame 2 is limited by the steel wire 4 to prevent the grinding disc 1 from loosening and flying off within the frame 2 due to excessive displacement," also includes limiting the displacement of the support plate 5 within the frame 2 by the steel wire 4 (the allowable displacement is the steel wire 4). The gap between the support plate 5 and the support plate mounting hole 51 is designed to prevent the support plate 5 from displacing too much within the skeleton 2, which would cause the point contact area between the support plate 5 and the grinding wheel base 3 to exceed the allowable value and reduce the risk of stress concentration fracture. In addition, the steel wire 4 can also prevent the support plate 5 from loosening and flying off within the skeleton 2 due to excessive displacement. Furthermore, the steel wire 4 helps to form an integrated structure of metal mesh and polymer material inside the skeleton 2. This structure is similar to a reinforced concrete structure, which helps to increase the strength of the skeleton 2 and prevent the skeleton 2 from breaking.

[0065] The beneficial effects of this embodiment are as follows: The steel wires inside the skeleton facilitate the formation of an integrated structure combining a metal mesh and polymer materials within the skeleton. This structure, similar to reinforced concrete, increases the skeleton's strength, preventing skeleton breakage and the loosening and detachment of the grinding discs and support plates within the skeleton. The steel wires couple the skeleton, grinding discs, and support plates, reducing positional changes in the grinding discs during grinding, resulting in more stable stress distribution and lowering the risk of stress concentration and fracture. Furthermore, this embodiment helps maintain the shape of the grinding surface in a normal state, thereby ensuring the grinding effect.

[0066] Furthermore, based on Embodiments 1 to 4, the width of the grinding disc mounting groove 11, the diameter of the grinding disc mounting hole 12, and the diameter of the support plate mounting hole 51 are all greater than the diameter of the steel wire 4, with a tolerance range of 0.1mm-1.0mm. Based on Examples 1 to 4, the annular shape of the steel wire 4 can be a complete annular shape or an annular shape composed of multiple circumferential arc segments; Grinding disc 1 is suitable for electroplated grinding discs. After adaptability adjustments, it can be used for powder metallurgy grinding discs, resin grinding discs, and ceramic grinding discs, which is beneficial to the expansion of grinding wheel applications.

[0067] It is worth noting that the above-mentioned mechanism, after adaptation, is applicable to cup-shaped wheels (including grinding discs) with radial multi-ring structures.
