Description

Technical Field

[0001] This utility model relates to the field of grinding, and in particular to a flexible diamond peripheral grinding wheel. Background Technology

[0002] In existing technologies, diamond peripheral grinding wheels are generally manufactured using methods such as electroplating or brazing to set diamond, or using methods such as powder metallurgy to impregnate diamond. Both methods involve rigid machining, where the outer diameter of the grinding ring makes hard contact with the workpiece during processing. This easily leads to chipping, high surface roughness, and poor cooling and chip removal capabilities of the grinding wheel. Consequently, progress in high-speed and high-precision machining is slowed and hindered. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flexible diamond peripheral grinding wheel to solve the above-mentioned problem.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A flexible diamond peripheral grinding wheel includes: multiple partition support blocks, multiple flexible grinding elements, and a grinding wheel base. The multiple partition support blocks and multiple flexible grinding elements alternately abut against each other circumferentially to form a grinding ring fixedly installed on the outer circumferential surface of the grinding wheel base. The flexible grinding element includes an elastic base plate and a grinding layer. The elastic base plate is disposed backward along the rotation direction of the grinding wheel. The grinding layer is fixed to one circumferential sidewall at one end of the elastic base plate. The other end of the elastic base plate is fixedly installed on the grinding wheel base, and is used to drive the elastic base plate to swing forward along the rotation direction of the grinding wheel under the action of centrifugal force generated by the rotation of the grinding wheel.

[0005] The beneficial effects of this utility model are as follows: the elastic substrate is set backward along the rotation direction of the grinding wheel, which is conducive to driving the elastic substrate to swing forward along the rotation direction of the grinding wheel under the action of centrifugal force generated by the rotation of the grinding wheel. This causes the end of the elastic substrate with the grinding layer to swing forward along the rotation direction of the grinding wheel, resulting in an increase in the diameter of the grinding ring. At the same time, combined with the elastic properties of the elastic substrate itself, elastic grinding is formed when the grinding ring and the workpiece come into contact, reducing the occurrence of edge breakage. Furthermore, the swing amplitude and force can be adjusted by changing the centrifugal force through the adjustment of the grinding wheel speed, thus achieving dual elastic processing.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the elastic substrate includes: an installation section, an elastic transition section, and a working section. The installation section and the working section are fixedly installed at both ends of the elastic transition section in a one-to-one correspondence. The grinding layer is fixed on one side wall of the circumferential direction of the working section. The installation section is fixedly installed on the grinding wheel base. The partition support block is adapted to and abuts against the installation section.

[0008] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the elastic substrate to achieve elastic grinding with the workpiece through the elastic transition section, thereby reducing the occurrence of edge breakage.

[0009] Furthermore, the grinding layer includes multiple diamond particles and a binder, with the multiple diamond particles being circumferentially fixed in a single layer to one side wall of the working section by the binder.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the diamond particles are arranged in a single layer in the binder, which is conducive to achieving the effect of grinding, cooling and chip removal at the same time; the rapid chip removal and instant cooling can significantly reduce the friction and frictional heat generated between the powder and the workpiece, reduce the processing load and save electricity costs.

[0011] Furthermore, the thickness of the binder in the circumferential direction of the grinding wheel is greater than or equal to the particle size of the diamond particles, but less than twice the particle size of the diamond particles.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that it helps to set the diamond particles in a single layer within the binder, thereby achieving good self-sharpening properties.

[0013] Furthermore, the separating support block has two opposing support surfaces, each of which corresponds to and abuts against two circumferentially adjacent elastic grinding parts. A dividing line is formed on the support surface to separate the elastic grinding parts. The dividing line is a broken line, a curve, or a straight line that is angled to the radial plane of the grinding wheel.

[0014] The beneficial effects of adopting the above-mentioned further solutions are: it helps to disperse stress concentration on the elastic substrate, improves the fatigue strength of the elastic substrate, and ensures that the elastic substrate is not easily broken.

[0015] Furthermore, a fixing groove is provided on the end face of the grinding wheel base. The fixing groove is an annular groove. One end of the separating support block and the other end of the elastic grinding element are adapted to and fixedly installed in the fixing groove.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the formation of a peripheral grinding wheel with the separation support block and the elastic grinding element fixedly installed on the outer peripheral surface of the grinding wheel base.

[0017] Furthermore, along the rotation direction of the grinding wheel, the elastic substrate is disposed behind the grinding layer.

[0018] The beneficial effects of adopting the above-mentioned further solutions are: it helps to reduce the requirements for the binder to hold diamond particles, thereby reducing the performance difficulty of the binder and reducing the amount of high-value materials used, thus reducing costs.

[0019] Furthermore, along the rotation direction of the grinding wheel, the elastic substrate is disposed in front of the grinding layer.

[0020] The beneficial effect of adopting the above-mentioned further solution is that it is a special method for scratch-free grinding, which can avoid scratch grinding, such as for high-requirement automotive glass grinding.

[0021] Furthermore, elastic grinding parts with various particle sizes, strengths, and rigidities are arranged alternately in the circumferential direction within the grinding ring.

[0022] The beneficial effects of adopting the above-mentioned further solutions are: by adjusting the configuration of elastic grinding components with different properties, such as adjusting the material, elasticity, strength, and bearing capacity of the elastic substrate, adjusting the geometric dimensions (thickness, width, length, etc.) and tilt angle of the elastic transition section, adjusting the bonding material of the grinding layer, adjusting the parameters (particle size, concentration, strength) of the diamond particles, etc., to adapt to different grinding processing requirements, so that the composite grinding ring has different properties, thereby realizing the multi-functional composite function of one wheel.

Detailed Implementation

[0026] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] like Figures 1 to 12 As shown, a flexible diamond peripheral grinding wheel includes: multiple partition support blocks 1, multiple flexible grinding elements 2, and a grinding wheel base 3. The multiple partition support blocks 1 and the multiple flexible grinding elements 2 alternately abut against each other circumferentially to form a grinding ring fixedly installed on the outer circumferential surface of the grinding wheel base 3. The flexible grinding element 2 includes an elastic base plate 21 and a grinding layer 22. The elastic base plate 21 is disposed backward along the rotation direction of the grinding wheel. The grinding layer 22 is fixed to one circumferential sidewall of one end of the elastic base plate 21. The other end of the elastic base plate 21 is fixedly installed on the grinding wheel base 3, and is used to drive the elastic base plate 21 to swing forward along the rotation direction of the grinding wheel under the action of centrifugal force generated by the rotation of the grinding wheel.

[0028] It should be noted that in this embodiment, the axial, circumferential, and radial directions are all based on the grinding ring formed by the alternating circumferential contact of the multiple partition support blocks 1 and the multiple elastic grinding elements 2. The peripheral grinding wheel, in conjunction with an adjustable speed motor, changes the centrifugal force by varying the rotation speed, enabling various grinding modes. For example, it alternates between a high-rigidity coarse-grained elastic grinding part 2 and a low-rigidity fine-grained elastic grinding part 2. When a low speed is selected, the coarse-grained elastic grinding part 2 is used primarily for roughing (at this time, the grinding wheel diameter is small). When a high speed is selected, the fine-grained elastic grinding part 2 is used primarily for machining (at this time, the grinding wheel diameter becomes larger, or even adjusted so that the coarse-grained grinding part does not participate in machining, that is, the dynamic diameter of the fine-grained elastic grinding part 2 is adjusted to be larger than the diameter of the coarse-grained elastic grinding part 2), significantly reducing the surface roughness of the workpiece and achieving the effect of one wheel serving two purposes.

[0029] The beneficial effects of this utility model are as follows: the elastic substrate is set backward along the rotation direction of the grinding wheel, which is conducive to driving the elastic substrate to swing forward along the rotation direction of the grinding wheel under the action of centrifugal force generated by the rotation of the grinding wheel. This causes the end of the elastic substrate with the grinding layer to swing forward along the rotation direction of the grinding wheel, resulting in an increase in the diameter of the grinding ring. At the same time, combined with the elastic properties of the elastic substrate itself, elastic grinding is formed when the grinding ring and the workpiece come into contact, reducing the occurrence of edge breakage. Furthermore, the swing amplitude and force can be adjusted by changing the centrifugal force through the adjustment of the grinding wheel speed, thus achieving dual elastic processing.

[0030] Preferred, such as Figure 3 and Figure 4 As shown, the elastic substrate 21 includes: a mounting section 211, an elastic transition section 212, and a working section 213. The mounting section 211 and the working section 213 are fixedly mounted at both ends of the elastic transition section 212 in a one-to-one correspondence. The grinding layer 22 is fixed on one side wall of the working section 213 in the circumferential direction. The mounting section 211 is fixedly mounted on the grinding wheel base 3. The partition support block 1 is adapted to and abuts against the mounting section 211.

[0031] It should be noted that in this embodiment, "the partition support block 1 and the mounting section 211 are adapted to abut against each other" means that the shape and size of the support surface 11 are the same as the shape and size of the mounting section 211. That is, when the partition support block 1 abuts against the elastic substrate 21, the support surface 11 on the partition support block 1 exactly overlaps with the mounting section 211 circumferentially. At this time, the overlapping part on the elastic substrate 21 is the mounting section 211, and the boundary between the mounting section 211 and the elastic transition section 212 is the dividing line 12 on the support surface 11.

[0032] The advantages of adopting the above preferred solution are: it facilitates elastic grinding between the elastic substrate and the workpiece through the elastic transition section, reducing the occurrence of edge bursting.

[0033] Preferred, such as Figure 6 and Figure 7 As shown, the grinding layer 22 includes a plurality of diamond particles 221 and a binder 222. The plurality of diamond particles 221 are circumferentially fixed to one side wall of the working section 213 by the binder 222 in a single layer.

[0034] It should be noted that in this embodiment, the elastic substrate 21 is made of spring steel. The spring steel material is beneficial for the working section 213 to act as a rigid backing substrate, supporting the diamond particles 221 when they are working, and avoiding the plastic deformation caused by the compression of the working section 213 by the diamond particles 221. This also helps to reduce the holding requirements of the binder 222 on the diamond particles 221, thereby reducing the performance difficulty of the binder 222 and reducing the amount of high-value materials used, thus reducing costs. The binder 222 is a single-material binder (such as electroplated nickel) or a composite material binder (such as brazing material), which is beneficial for bonding diamond particles 221 to the circumferential sidewall of the working section 211 through different bonding processes, thereby enhancing the stability of the bonding of diamond particles 221, reducing manufacturing costs, and improving the performance of binder 222.

[0035] The advantages of adopting the above-mentioned preferred solution are: the diamond particles are arranged in a single layer in the binder, which is conducive to achieving the effect of grinding, cooling and chip removal at the same time; the rapid chip removal and instant cooling can significantly reduce the friction and frictional heat generated between the powder and the workpiece, reduce the processing load and save electricity costs.

[0036] Preferably, the thickness of the binder 222 in the circumferential direction of the grinding wheel is greater than or equal to the particle size of the diamond particles 221, and less than twice the particle size of the diamond particles 221.

[0037] The advantages of adopting the above-mentioned preferred scheme are: it helps to set diamond particles in a single layer within the binder, thereby achieving good self-sharpening properties.

[0038] Preferred, such as Figure 4 As shown, the separating support block 1 has two opposing support surfaces 11, and the two support surfaces 11 correspond one-to-one with the two circumferentially adjacent elastic grinding parts 2. A dividing line 12 is formed on the support surface 11 to separate the elastic grinding parts 2. The dividing line 12 is a broken line, a curve, or a straight line that is angled to the radial plane of the grinding wheel.

[0039] It should be noted that in this embodiment, the support surface 11 abuts against the mounting section 211; For peripheral grinding wheels in the prior art, the dividing line is a straight line parallel to the central axis of the grinding wheel. Therefore, in this embodiment, the dividing line 12 is a broken line, a curve, or a straight line set at an angle to the radial plane of the grinding wheel, which means that the dividing line 12 is not parallel to the central axis of the peripheral grinding wheel. The "radial plane" and "axial plane" are defined with the central axis of the grinding wheel or grinding ring as the reference. The "radial plane" is the plane perpendicular to the central axis, that is, the plane formed by cutting across the central axis. The "axial plane" is the plane passing through the central axis, that is, the plane formed by cutting along the central axis. The "radial plane" and "axial plane" are perpendicular to each other. In addition to a complete arc, a "curve" also includes a line formed by the smooth connection of multiple straight lines and multiple curved lines.

[0040] The advantages of adopting the above preferred solution are: it helps to disperse stress concentration on the elastic substrate, improves the fatigue strength of the elastic substrate, and ensures that the elastic substrate is not easily broken.

[0041] Preferred, such as Figure 3 and Figure 4 As shown, a fixing groove 31 is provided on the end face of the grinding wheel base 3. The fixing groove 31 is an annular groove. One end of the separating support block 1 and the other end of the elastic grinding part 2 are adapted and fixedly installed in the fixing groove 31.

[0042] It should be noted that in this embodiment, one end of the partition support block 1 is adapted to and fixedly installed in the mounting section 211 within the fixing groove 31.

[0043] The advantages of adopting the above preferred solution are: it helps to form a peripheral grinding wheel that is fixedly installed on the outer peripheral surface of the grinding wheel base by the partition support block and the elastic grinding part.

[0044] Preferably, in this embodiment, such as Figures 1 to 4 , Figures 8 to 10 As shown, along the rotation direction of the grinding wheel, the elastic substrate 21 is disposed behind the grinding layer 22, which helps to reduce the binding requirements of the binder 222 on the diamond particles 221, thereby reducing the performance difficulty of the binder 222 and reducing the amount of high-value materials used, thus reducing costs.

[0045] Preferably, in another embodiment, such as Figure 11 and Figure 12 As shown, along the rotation direction of the grinding wheel, the elastic substrate 21 is disposed in front of the grinding layer 22. This embodiment is a special case applied to the grinding of automotive glass. It is beneficial to make the diamond particles 221 that fall off during processing fall into the gap between two adjacent elastic grinding parts 2 along the rotation direction of the grinding wheel, thereby avoiding scratching the automotive glass.

[0046] Preferred, such as Figures 8 to 10 As shown, elastic grinding parts 2 with various particle sizes, strengths and rigidities are arranged alternately in the circumferential direction in the grinding ring.

[0047] It should be noted that in this embodiment, "particle size" refers to the coarseness of the diamond particles 221 in the elastic grinding part 2, and "strength and rigidity" refers to the strength and rigidity of the elastic substrate 21 in the elastic grinding part 2; and the elastic grinding part 2 with relatively fine particle size has relatively low strength and rigidity. "Circumferential alternation setting" refers to the circumferential alternation between "first-stage elastic grinding part 2 with relatively coarse grit, high strength and rigidity" and "second-stage elastic grinding part 2 with relatively fine grit, low strength and rigidity" along the rotation direction of the grinding wheel. However, in the circumferential alternation setting, it is only necessary to maintain the first-stage elastic grinding part 2, the second-stage elastic grinding part 2, the first-stage elastic grinding part 2, the second-stage elastic grinding part 2, and so on. As for the number of elastic grinding parts 2 in each stage, they can be the same or different. The advantage of this setting is that when the relatively coarse-grained first-stage elastic grinding part 2 grinds the surface of the workpiece, the roughness of the workpiece surface is poor because of the coarse grit 221 it uses. Then, under the action of centrifugal force, the relatively fine-grained second-stage elastic grinding part 2 swings forward along the rotation direction of the grinding wheel, causing the diameter of the grinding ring to increase. At this time, because the diamond grit 221 it uses is fine, when it grinds the surface of the workpiece, it will further reduce the roughness of the workpiece surface. like Figure 10 As shown, there are two stages of elastic grinding parts 2. The diamond particles 221 in the first stage elastic grinding part 2 are coarse-grained, and the elastic substrate 21 is made of spring steel, which has high strength and rigidity (in the first stage elastic grinding part 2, the grinding layer 22 is fixed on the working section 213 made of spring steel). The diamond particles 221 in the second stage elastic grinding part 2 are fine-grained, and the elastic substrate 21 is made of thermoplastic material, which has low strength and rigidity (in the second stage elastic grinding part 2, the working section 213 is still made of spring steel, and the grinding layer 22 is still fixed on the working section 213, and the mounting section 211 and the elastic transition section are also present). 212 is made of thermoplastic material. The working section 213 and the grinding layer 22 are fixed in the thermoplastic material through an insert molding process. The thermoplastic material can replace the partition support block 1. That is, the mounting section 211 made of thermoplastic material abuts against the mounting section 211 in the first-stage elastic grinding part 2 on both sides of its circumference. In the two-stage elastic grinding parts 2, each stage of elastic grinding part 2 has only one elastic grinding part 2. That is, a first-stage elastic grinding part 2 and a second-stage elastic grinding part 2 are circumferentially alternately arranged to form a grinding ring. The fine-grained elastic grinding part 2 plays an auxiliary role in reducing the surface roughness of the grinding surface.

[0048] The beneficial effects of adopting the above-mentioned preferred scheme are: by adjusting the configuration of elastic grinding parts with different properties, such as adjusting the material, elasticity, strength, and bearing capacity of the elastic substrate, adjusting the geometric dimensions (thickness, width, length, etc.) and tilt angle of the elastic transition section, adjusting the bonding material of the grinding layer, adjusting the parameters (particle size, concentration, strength) of the diamond particles, etc., to adapt to different grinding processing requirements, so that the composite grinding ring has different properties, thereby realizing the multi-functional composite function of one wheel.

[0049] This utility model can be combined with anti-deformation structure technology (such as ZL202410463241.3, an electroplated single-layer diamond anti-deformation grinding part, grinding ring and irregular grinding wheel), dressing-free technology (such as ZL202211657393.4, an anti-dressing diamond irregular grinding wheel), and scratch-free technology (such as ZL202410463242.8, a diamond abrasive tool that avoids scratching the workpiece) to form a multi-composite structure grinding wheel. This is beneficial to significantly improve the performance of the peripheral grinding wheel, improve the anti-deformation ability of the peripheral grinding wheel to improve efficiency, simplify or eliminate the repair process, reduce costs, and solve the problem of difficult-to-machine grinding of scratch-free workpieces to achieve high-quality processing (such as processing high-end automotive glass, which can avoid the phenomenon of diamond particles falling off and crushing into marks).

[0050] The following describes three embodiments of this utility model: Example 1.

[0051] like Figures 1 to 4 As shown, multiple partition support blocks 1 and multiple elastic grinding elements 2 alternately abut against each other in the circumferential direction to form a grinding ring fixedly installed on the outer circumferential surface of the grinding wheel base 3; among the multiple elastic grinding elements 2, the particle size of the diamond particles 221, the strength and rigidity of the elastic substrate 21 are all the same; along the rotation direction of the grinding wheel, the elastic substrate 21 is disposed behind the grinding layer 22.

[0052] Example 2.

[0053] like Figures 8 to 10 As shown, the diamond particles 221 in the first-stage elastic grinding part 2 are coarse, and the elastic substrate 21 is made of spring steel, which has high strength and rigidity. The diamond particles 221 in the second-stage elastic grinding part 2 are fine, and the elastic substrate 21 is made of thermoplastic material, which has low strength and rigidity. In the two-stage elastic grinding parts 2, each stage of elastic grinding part 2 has only one elastic grinding part 2, that is, one first-stage elastic grinding part 2 and one second-stage elastic grinding part 2 are arranged alternately in the circumferential direction to form a grinding ring. Along the rotation direction of the grinding wheel, the elastic substrate 21 is located behind the grinding layer 22.

[0054] Example 3.
