Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and in particular to a high-strength brown corundum wear-resistant resin grinding wheel. Background Technology

[0002] In industrial fields such as machining, building material grinding, and metal surface treatment, grinding wheels are important grinding tools whose performance directly affects processing efficiency, workpiece accuracy, and production costs. Brown fused alumina, due to its high hardness, good toughness, and strong wear resistance, is often used as an abrasive in grinding wheel preparation. Resin binders, with their advantages of fast curing speed, high wheel strength, and good self-sharpening properties, have become a commonly used binder type for brown fused alumina grinding wheels. Therefore, brown fused alumina wear-resistant resin grinding wheels are widely used in various roughing and semi-finishing operations.

[0003] Traditional grinding wheels are mostly of an integrated structure, with the wheel core, transition layer and abrasive ring being inseparable. When the abrasive ring wears out due to long-term grinding, the entire grinding wheel needs to be replaced, resulting in the waste of unworn parts such as the wheel core, which greatly increases the cost of equipment use and does not conform to the concept of resource conservation. Based on this, a high-strength brown corundum wear-resistant resin grinding wheel is proposed for improvement. Utility Model Content

[0004] Given that most existing grinding wheels are of an integrated structure, the entire grinding wheel needs to be replaced when the abrasive ring wears out due to long-term grinding, which increases the cost of equipment use. Therefore, this utility model was proposed.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a high-strength brown corundum wear-resistant resin grinding wheel, including a wheel core, a transition layer is provided on the outside of the wheel core, an abrasive ring is provided on the outside of the transition layer, and the transition layer and the abrasive ring are detachably connected by bolts; The transition layer has a number of protruding teeth distributed around one side of its surface, and the abrasive ring has a number of grooves on its inner wall, with the protruding teeth fitting into the inner wall of the grooves. An annular limiting plate is fixedly sleeved on the other side of the transition layer surface, and an annular groove is opened on one side of the abrasive ring, with the annular limiting plate fitted into the inner wall of the annular groove.

[0006] As a preferred embodiment, the transition layer has symmetrically provided mounting grooves at one end, and the abrasive ring has symmetrically provided mounting blocks on the other side, with the mounting blocks fitting into the inner wall of the mounting groove.

[0007] As a preferred embodiment, the inner wall of the mounting groove is provided with a first screw hole, and the inside of the mounting block is provided with a second screw hole. The first screw hole and the second screw hole are threadedly connected to the same bolt, and the bolts are arranged symmetrically.

[0008] As a preferred embodiment, the abrasive ring has several heat dissipation grooves on its surface and several annular reinforcing ribs inside.

[0009] As a preferred embodiment, the abrasive ring thickness gradually decreases from the edge to the center, and the abrasive ring edge is designed with rounded corners.

[0010] As a preferred embodiment, the wheel core has an axle hole inside, and the wheel core has several mounting holes distributed around its circumference.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model uses the circumferential limiting of the teeth and grooves, the axial limiting of the annular limiting plate and the annular groove, and the mounting block and the mounting groove, plus the fastening effect of the bolts, to make the connection between the transition layer and the abrasive ring extremely stable. When the abrasive ring is worn, it can be replaced simply by removing the bolts. The wheel core and the transition layer can be reused without replacing the entire grinding wheel, which greatly reduces the cost of equipment use, reduces resource waste, and makes it easy to replace abrasive rings of different grit sizes according to processing requirements.

[0012] 2. This utility model achieves heat dissipation and chip removal through heat dissipation grooves, extending the service life of the abrasive ring and ensuring the quality of the machined surface. The annular reinforcing ribs can disperse the radial and circumferential stress of the abrasive ring, ensuring its structural stability. The abrasive ring thickness gradually decreases from the edge to the center, reducing unnecessary material consumption and lowering the overall weight. The rounded corner design at the edges can reduce chipping of the workpiece edge during grinding, while also reducing stress concentration at the edge of the grinding wheel, making the grinding wheel more reliable in grinding operations and applicable to a wider range of scenarios.

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a high-strength brown corundum wear-resistant resin grinding wheel, including a wheel core 1, a transition layer 2 on the outside of the wheel core 1, an abrasive ring 3 on the outside of the transition layer 2, and the transition layer 2 and the abrasive ring 3 are detachably connected by bolts 4. The transition layer 2 has several protruding teeth 21 distributed around one side of its surface, and the abrasive ring 3 has several grooves 31 on its inner wall, with the protruding teeth 21 fitting into the inner wall of the grooves 31. An annular limiting plate 22 is fixedly sleeved on the other side of the surface of the transition layer 2, and an annular groove 32 is opened on one side of the abrasive ring 3, with the annular limiting plate 22 fitted into the inner wall of the annular groove 32. The transition layer 2 has symmetrically provided mounting grooves 23 at one end, and the abrasive ring 3 has symmetrically provided mounting blocks 33 on the other side. The mounting blocks 33 are fitted into the inner wall of the mounting groove 23. The inner wall of the mounting groove 23 has a first screw hole 24, and the inside of the mounting block 33 has a second screw hole 34. The first screw hole 24 and the second screw hole 34 are threaded together by the same bolt 4, and the bolt 4 is symmetrically arranged.

[0017] During use, when the grinding wheel is working, the wheel core 1 serves as the basic support component, connects to the drive equipment and transmits power, driving the whole to rotate at high speed. During the rotation, the outermost abrasive ring 3 directly contacts the workpiece to be processed, utilizing the high hardness and wear resistance of brown corundum abrasive to achieve grinding operations. The protruding teeth 21 are fitted into the groove 31 to form a circumferential limit, preventing the abrasive ring 3 from sliding circumferentially relative to the transition layer 2; the annular limiting plate 22 is fitted into the annular groove 32, and together with the fitting structure of the mounting block 33 and the mounting groove 23, it restricts the displacement of the abrasive ring 3 axially, preventing it from axially moving during high-speed rotation; the bolts 4 pass through the first screw hole 24 and the second screw hole 34 to fasten the mounting block 33 to the mounting groove 23, further strengthening the connection stability between the transition layer 2 and the abrasive ring 3, ensuring that the entire grinding wheel maintains structural stability during high-intensity grinding operations and efficiently completes the processing task; When the abrasive ring 3 wears to a certain extent, the transition layer 2 and the abrasive ring 3 can be separated by removing the bolt 4, and a new abrasive ring 3 can be replaced and then reassembled. This allows the wheel core 1 and the transition layer 2 to be reused without replacing the entire grinding wheel, reducing the cost of use, and making it easy to replace abrasive rings 3 of different grit sizes according to processing requirements.

[0018] Reference Figures 1-4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the surface of the abrasive ring 3 is provided with a plurality of heat dissipation grooves 5, and the interior of the abrasive ring 3 is provided with a plurality of annular reinforcing ribs 6; The thickness of the abrasive ring 3 gradually decreases from the edge to the center, and the edge of the abrasive ring 3 is designed with rounded corners.

[0019] During use, the heat dissipation groove 5 can increase the contact area with air, accelerate heat dissipation, thereby extending the service life of the abrasive ring 3. At the same time, it can also serve as a chip removal channel to promptly remove the chips generated during grinding, avoid affecting the grinding accuracy, and ensure the quality of the processed surface. The annular reinforcing rib 6 can disperse the radial and circumferential stress of the abrasive ring 3, prevent the abrasive ring 3 from cracking or deforming due to excessive stress, and ensure its structural stability. The thickness of the abrasive ring 3 gradually decreases from the edge to the center, reducing unnecessary material consumption and overall weight. The rounded edges reduce chipping of the workpiece edge during grinding, while also reducing stress concentration at the edge of the grinding wheel and extending its service life.

[0020] Reference Figures 1-4 This is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that: the wheel core 1 has an axle hole 11 inside, and a number of mounting holes 12 are distributed around the inside of the wheel core 1.

[0021] During use, the shaft hole 11 is the direct connection channel between the wheel core 1 and the motor spindle, realizing stable power transmission and ensuring that the wheel core 1 can drive the entire structure such as the transition layer 2 and the abrasive ring 3 to rotate synchronously at high speed, providing core power support for grinding operations; Several mounting holes 12 are distributed along the inner circumference of the wheel core 1, and the wheel core 1 can be connected to the flange of the drive equipment by means of connecting parts such as pins, which further enhances the connection strength between the wheel core 1 and the drive end and prevents relative slippage or loosening during high-speed rotation.

[0022] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
