Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding wheel technology, and more specifically, to a novel diamond surface grinding wheel. Background Technology
[0002] Diamond surface grinding wheels are high-efficiency precision tools that use diamond as an abrasive and are specifically designed for grinding the surface of workpieces. Due to their extremely high hardness and wear resistance, diamond grinding wheels are widely used in surface grinding and can be used to grind hard and brittle materials such as cemented carbide, ceramics, and glass.
[0003] After prolonged use, the annular ceramic grinding wheel is prone to wear and needs to be replaced. Currently, the annular ceramic grinding wheel is fixed to the conductive substrate, requiring the entire grinding wheel to be replaced, which increases the cost of replacing the grinding wheel.
[0004] A search revealed that Chinese patent CN216608657U discloses a PCD composite diamond tool grinding wheel. With prolonged use, when replacing the annular ceramic grinding wheel, multiple nuts can be loosened and multiple screws removed, thus separating the conductive connecting ring from the annular boss. The conductive connecting ring can then be disassembled to replace the next annular ceramic grinding wheel. When replacing the next annular ceramic grinding wheel, the above steps are reversed for installation. When the conductive connecting ring is fitted onto the outer wall of the base material, four limiting blocks are simultaneously inserted into four limiting slots, quickly aligning the mounting holes on the conductive connecting ring and the annular boss. The upper ends of the multiple screws are located inside multiple blind holes.
[0005] However, in actual use, when replacing the annular ceramic grinding wheel, it is necessary to loosen and remove multiple nuts and screws to separate the conductive connecting ring from the annular boss, and then remove the conductive connecting ring. The replacement is then carried out in reverse order, making the replacement process cumbersome and time-consuming. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a novel diamond surface grinding wheel to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A novel diamond surface grinding wheel includes a grinding wheel base, a mounting hole is provided in the center of the grinding wheel base, a groove is provided on the surface of the grinding wheel base, a diamond abrasive layer is inserted into one side of the groove, and an abrasive mechanism is provided on one side of the diamond abrasive layer.
[0009] The abrasive mechanism includes a first abrasive layer and a second abrasive layer fixedly disposed on the surface of the diamond abrasive layer. The first abrasive layer is fixedly disposed in a ring on one side of the second abrasive layer. A third abrasive layer is fixedly disposed in a ring on the surface of the second abrasive layer. The abrasive grit size of the first abrasive layer, the second abrasive layer and the third abrasive layer increases sequentially. A plurality of chip-receiving grooves are formed in a ring on the surface of the first abrasive layer, the second abrasive layer and the third abrasive layer. A fixing groove is formed on the surface of the grinding wheel base. A reinforcing rib is fixedly disposed inside the fixing groove.
[0010] By adopting the above technical solution, the first abrasive layer, the second abrasive layer and the third abrasive layer are distributed in a ring and the abrasive grain size increases sequentially, which can perform step grinding on the workpiece, improve the processing accuracy and surface finish, and the ring-shaped chip groove can collect the grinding chips in time, avoiding accumulation and affecting the grinding effect.
[0011] As a further description of the above technical solution: an auxiliary mechanism is provided on one side of the grinding wheel base. The auxiliary mechanism includes multiple threaded holes opened on the surface of the grinding wheel base. Multiple threaded grooves are opened in an annular shape on the surface of the diamond abrasive layer. Anti-loosening bolts are threadedly connected inside the threaded holes and threaded grooves.
[0012] The surface of the grinding wheel base is provided with a plurality of heat dissipation grooves in a ring shape, and heat dissipation fins are inserted into the interior of the heat dissipation grooves. The heat dissipation fins are designed to be arc-shaped.
[0013] By adopting the above technical solution: the threaded hole, the annular threaded groove and the anti-loosening bolt are used to fix the diamond abrasive layer firmly, prevent it from loosening and falling off, and ensure grinding stability. In addition, the arc-shaped heat sink in the annular heat sink increases the heat dissipation area, accelerates heat dissipation, avoids high temperature from affecting the performance of the grinding wheel and the workpiece, and extends the service life of the grinding wheel.
[0014] As a further description of the above technical solution: a mounting ring is fixedly provided on one side of the grinding wheel base, and the surface of the mounting ring is provided with a plurality of mounting threaded holes in an annular shape;
[0015] The reinforcing rib is made of high-strength steel, the grinding wheel base is made of high-strength alloy material, and an anti-loosening washer is fixed between the anti-loosening bolt and the grinding wheel base. The anti-loosening washer is made of rubber.
[0016] By adopting the above technical solution, the mounting ring on one side of the grinding wheel base and the annular mounting threaded hole on the surface facilitate a stable connection between the grinding wheel and the equipment, improving the ease and stability of installation. Moreover, the reinforcing ribs made of high-strength steel and the grinding wheel base made of high-strength alloy material enhance the overall structural strength and improve the resistance to deformation.
[0017] The technical effects and advantages of this utility model are as follows:
[0018] 1. By setting up an abrasive mechanism, compared with the existing technology, the first, second and third abrasive layers adopt a design with progressively increasing abrasive size, realizing step-by-step grinding of the workpiece surface. The first abrasive layer efficiently removes surface protrusions and impurities, the second abrasive layer improves the flatness, and finally the third abrasive layer completes the fine grinding, which greatly improves the surface finish of the workpiece, balances the efficiency of rough grinding and the quality of fine grinding, and is suitable for different processing needs. Moreover, the chip grooves on the surface of each abrasive layer can collect grinding chips in time, avoid accumulation and hinder grinding, reduce secondary scratches on the workpiece surface, and ensure processing continuity. Furthermore, with the heat dissipation grooves and arc-shaped heat sinks, grinding heat can be quickly dissipated, preventing the grinding wheel performance from deteriorating and the workpiece from thermal deformation due to high temperature, extending the service life of the grinding wheel, and ensuring stable processing accuracy.
[0019] 2. By setting up an auxiliary mechanism, compared with the existing technology, the diamond abrasive layer can be firmly fixed in the groove of the grinding wheel base through the cooperation of threaded holes, threaded grooves and anti-loosening bolts, forming a rigid connection. This prevents the abrasive layer from shifting or falling off due to stress during grinding, ensuring the stability of the grinding process. Moreover, the rubber anti-loosening gasket between the anti-loosening bolt and the grinding wheel base can use the elasticity of rubber to compensate for the vibration gap, effectively preventing the bolt from loosening during high-speed rotation and continuous vibration, maintaining the long-term tightness of the connection. Furthermore, this mechanism, together with the reinforcing ribs made of high-strength steel and the grinding wheel base made of high-strength alloy material, further strengthens the overall structural strength of the grinding wheel, resists the centrifugal force and grinding impact force during high-speed rotation, reduces the risk of deformation, and ensures grinding accuracy and operational safety.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] The embodiments disclosed in this application are as follows: Figure 1-5 The present invention relates to a novel diamond surface grinding wheel, comprising a grinding wheel base 1, a mounting hole 2 formed in the center of the grinding wheel base 1, a groove formed on the surface of the grinding wheel base 1, a diamond abrasive layer 3 inserted into one side of the groove, and an abrasive mechanism provided on one side of the diamond abrasive layer 3.
[0028] The abrasive mechanism includes a first abrasive layer 4 and a second abrasive layer 5 fixedly disposed on the surface of the diamond abrasive layer 3. The first abrasive layer 4 is fixedly disposed in a ring on one side of the second abrasive layer 5. A third abrasive layer 6 is fixedly disposed in a ring on the surface of the second abrasive layer 5. The abrasive size of the first abrasive layer 4, the second abrasive layer 5 and the third abrasive layer 6 increases sequentially. Several chip grooves 7 are opened in a ring on the surface of the first abrasive layer 4, the second abrasive layer 5 and the third abrasive layer 6. A fixing groove 8 is opened on the surface of the grinding wheel base 1. A reinforcing rib 9 is fixedly disposed inside the fixing groove 8.
[0029] The grinding wheel begins to rotate at high speed. At this time, the first abrasive layer 4, the second abrasive layer 5, and the third abrasive layer 6 rotate together with the grinding wheel base 1. Since the abrasive size of the three layers increases sequentially, the workpiece surface can be gradually and finely ground. First, the first abrasive layer 4 with a smaller abrasive size performs preliminary rough grinding on the workpiece surface to remove obvious protrusions and impurities. Then, the second abrasive layer 5 with a slightly larger abrasive size performs further grinding to make the workpiece surface smoother. Finally, the third abrasive layer 6 with the largest abrasive size performs fine grinding to improve the surface finish of the workpiece.
[0030] Furthermore, during the grinding process, the chip grooves 7 on the surfaces of the first abrasive layer 4, the second abrasive layer 5, and the third abrasive layer 6 can promptly accommodate the grinding chips, preventing chip accumulation from affecting the grinding effect. At the same time, the multiple heat dissipation grooves 13 on the surface of the grinding wheel base 1 and the internally inserted arc-shaped heat dissipation fins 14 can quickly dissipate the heat generated during grinding, avoiding the impact of excessive temperature on the performance of the grinding wheel and the workpiece.
[0031] Reference Figure 2-3As shown, an auxiliary mechanism is provided on one side of the grinding wheel base 1. The auxiliary mechanism includes multiple threaded holes 10 opened on the surface of the grinding wheel base 1. Multiple threaded grooves 11 are opened in a ring on the surface of the diamond abrasive layer 3. Anti-loosening bolts 12 are threadedly connected inside the threaded holes 10 and the threaded grooves 11.
[0032] The surface of the grinding wheel base 1 is provided with multiple heat dissipation grooves 13 in a ring shape. Heat dissipation fins 14 are inserted into the heat dissipation grooves 13 and are arc-shaped.
[0033] The reinforcing ribs 9 in the fixing grooves 8 on the surface of the grinding wheel base 1 are made of high-strength steel. They work together with the grinding wheel base 1, which is made of high-strength alloy material, to enhance the overall structural strength and rigidity of the grinding wheel. This ensures that the grinding wheel is not easily deformed when rotating at high speed and under grinding stress. In addition, the threaded holes 10, threaded grooves 11, and anti-loosening bolts 12 in the auxiliary mechanism further securely fix the diamond abrasive layer 3 to the grinding wheel base 1. The rubber anti-loosening gaskets 17 between the anti-loosening bolts 12 and the grinding wheel base 1 prevent the bolts from loosening during vibration, ensuring the reliability of the connection between the diamond abrasive layer 3 and the grinding wheel base 1.
[0034] Reference Figure 4-5 As shown, a mounting ring 15 is fixedly provided on one side of the grinding wheel base 1, and the surface of the mounting ring 15 is provided with a plurality of mounting threaded holes 16 in a ring shape.
[0035] The reinforcing rib 9 is made of high-strength steel, the grinding wheel base 1 is made of high-strength alloy material, and an anti-loosening washer 17 is fixed between the anti-loosening bolt 12 and the grinding wheel base 1. The anti-loosening washer 17 is made of rubber.
[0036] The grinding wheel is initially positioned with the spindle of the grinding equipment through the mounting hole 2 in the center of the grinding wheel base 1. Then, using the multiple mounting threaded holes 16 on the surface of the mounting ring 15, the grinding wheel is firmly fixed to the equipment with bolts to ensure that the grinding wheel will not shift when rotating at high speed. Then, the diamond abrasive layer 3 is firmly fixed in the groove of the grinding wheel base 1. At the same time, it is confirmed that the rubber anti-loosening washer 17 on the head of the anti-loosening bolt 12 is intact to ensure the reliability of the connection.
[0037] Working principle of this utility model:
[0038] This utility model is a novel diamond surface grinding wheel. First, the grinding wheel is initially positioned with the spindle of the grinding equipment through the mounting hole 2 in the center of the grinding wheel base 1. Then, using the multiple mounting threaded holes 16 on the surface of the mounting ring 15, the grinding wheel is firmly fixed to the equipment with bolts to ensure that the grinding wheel will not be displaced when rotating at high speed. Then, the diamond abrasive layer 3 is firmly fixed in the groove of the grinding wheel base 1. At the same time, it is confirmed that the rubber anti-loosening washer 17 on the head of the anti-loosening bolt 12 is intact to ensure the reliability of the connection.
[0039] During the grinding start-up phase, after the equipment is started, the grinding wheel begins to rotate at high speed. At this time, the first abrasive layer 4, the second abrasive layer 5, and the third abrasive layer 6 rotate together with the grinding wheel base 1. Since the abrasive size of the three layers increases sequentially, the workpiece surface can be gradually and finely ground. First, the first abrasive layer 4 with a smaller abrasive size performs preliminary rough grinding on the workpiece surface to remove more obvious protrusions and impurities. Then, the second abrasive layer 5 with a slightly larger abrasive size performs further grinding to make the workpiece surface smoother. Finally, the third abrasive layer 6 with the largest abrasive size performs fine grinding to improve the surface finish of the workpiece.
[0040] Moreover, during the grinding process, the chip grooves 7 opened on the surfaces of the first abrasive layer 4, the second abrasive layer 5 and the third abrasive layer 6 can promptly accommodate the chips generated during grinding, preventing chip accumulation from affecting the grinding effect. At the same time, the multiple heat dissipation grooves 13 opened on the surface of the grinding wheel base 1 and the internally inserted arc-shaped heat dissipation fins 14 can quickly dissipate the heat generated during grinding, avoiding the impact of excessive temperature on the performance of the grinding wheel and the workpiece.
[0041] Secondly, the reinforcing ribs 9 in the fixing grooves 8 on the surface of the grinding wheel base 1 are made of high-strength steel, which cooperate with the grinding wheel base 1 made of high-strength alloy material to enhance the overall structural strength and rigidity of the grinding wheel, ensuring that the grinding wheel is not easily deformed when rotating at high speed and under grinding force. In addition, the threaded holes 10, threaded grooves 11 and threaded anti-loosening bolts 12 in the auxiliary mechanism further fix the diamond abrasive layer 3 firmly to the grinding wheel base 1. The rubber anti-loosening gaskets 17 between the anti-loosening bolts 12 and the grinding wheel base 1 prevent the bolts from loosening during vibration, ensuring the reliability of the connection between the diamond abrasive layer 3 and the grinding wheel base 1.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
