Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and more specifically, to a high-precision flat diamond grinding wheel. Background Technology

[0002] In the current era of booming modern manufacturing, the requirements for workpiece machining accuracy in fields such as precision machining, optical lens manufacturing, and electronic component processing have reached unprecedented levels. High-precision flat diamond grinding wheels, as the core tool for achieving these high-precision machining processes, are closely linked to the challenges currently facing the industry.

[0003] During the grinding process, workpiece material debris, particles generated by abrasive wear, and impurities in the coolant will adhere to the surface of the diamond grinding wheel. On the one hand, these impurities will block the gaps between the diamond abrasive grains, preventing the grains from cutting normally and reducing the cutting performance of the grinding wheel. On the other hand, the accumulation of impurities may cause uneven local stress on the surface of the grinding wheel, aggravating the wear of the grinding wheel, and even causing the grinding wheel to become unbalanced, further affecting the grinding accuracy. Utility Model Content

[0004] In order to overcome the problems and defects in the prior art, this utility model provides a high-precision flat diamond grinding wheel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision flat grinding diamond grinding wheel, comprising a diamond grinding wheel body, an installation bushing fixedly installed inside the diamond grinding wheel body, a fixing ring rotatably connected to the outside of the installation bushing, a connecting plate fixedly connected to the top of the fixing ring, and a cleaning mechanism provided on the top of the connecting plate;

[0006] The cleaning mechanism includes a fixed shell, which is fixed to the top of a connecting plate. A fixed plate is fixedly connected to the top of the fixed shell. A groove is formed on the bottom surface of the fixed plate. A fixed spring is fixedly connected to the bottom of the inner wall of the groove. A fixed scraper is fixedly connected to the bottom end of the fixed spring. A fan is fixedly installed on the top of the fixed plate. A connecting air pipe is fixedly connected to one side of the fan. An air jet head is fixedly connected to the bottom of the connecting air pipe. A positioning mechanism is provided inside the fixed shell.

[0007] Preferably, the retaining ring is rotatably connected to the diamond grinding wheel body, and the number of both the retaining ring and the connecting plate is set to two.

[0008] Preferably, one end of the jet head penetrates through the fixed shell and extends into the interior of the fixed shell.

[0009] Preferably, the cross-sectional shape of the fixed shell is set to arc.

[0010] Preferably, the positioning mechanism includes a fixing block, and the number of fixing blocks is set to multiple, with the multiple fixing blocks evenly fixed on both sides of the inner wall of the fixing shell.

[0011] Preferably, a plurality of the fixing blocks are internally connected with ball bearings, which are in contact with the surface of the diamond grinding wheel body.

[0012] Preferably, the fixing spring is made of carbon steel, the bottom of the fixing plate penetrates through the fixing shell and extends into the interior of the fixing shell, and the fixing scraper is slidably connected to the groove.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. The cleaning mechanism, through the synergistic action of the fixed scraper and the air jet head, thoroughly removes dirt, debris, and other impurities adhering to the surface of the diamond grinding wheel. The elastic pressure applied by the fixed spring ensures close contact between the fixed scraper and the grinding wheel surface, adapting to minute changes in the grinding wheel surface and efficiently removing impurities. The high-speed airflow generated by the blower is ejected from the air jet head through the connecting air pipe, blowing away the fine impurities remaining after scraping by the scraper. This ensures that the diamond abrasive grains on the surface of the diamond grinding wheel always maintain a clear cutting edge, preventing impurities from clogging the abrasive grain gaps or interfering with the cutting process, ensuring the grinding wheel's continuous and stable grinding capability, thereby improving the surface finish of the workpiece. The cleaning effect avoids cutting deviations caused by impurities, allowing this flat diamond grinding wheel to maintain high processing accuracy during long-term use, improving the product qualification rate, and making it particularly suitable for precision machining fields with high precision requirements.

[0015] 2. By rolling along with the diamond grinding wheel body at high speed and forming a circumferential limit, the radial runout is effectively restricted, ensuring that the diamond grinding wheel body always rotates stably around the set axis. This provides a stable reference for grinding, reduces machining deviations caused by grinding wheel wobbling, and fundamentally guarantees the positional and shape accuracy of grinding. It also effectively controls the dimensional and geometric tolerances of the workpiece. The limiting effect of the balls reduces errors caused by vibration. Because impurities are removed in time, abnormal wear caused by impurity compression of abrasive grains is reduced. At the same time, the stable rotation state also reduces uneven wear of the grinding wheel, thereby extending the service life of the diamond grinding wheel body and reducing production costs.

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.

[0023] As attached Figure 1-5 The high-precision flat grinding diamond grinding wheel shown includes a diamond grinding wheel body 1, an installation bushing 2 is fixedly installed inside the diamond grinding wheel body 1, a fixing ring 3 is rotatably connected to the outside of the installation bushing 2, a connecting plate 4 is fixedly connected to the top of the fixing ring 3, and a cleaning mechanism is provided on the top of the connecting plate 4.

[0024] The cleaning mechanism includes a fixed shell 5, which is fixed to the top of the connecting plate 4. A fixed plate 6 is fixedly connected to the top of the fixed shell 5. A groove 7 is opened on the bottom surface of the fixed plate 6. A fixed spring 8 is fixedly connected to the bottom of the inner wall of the groove 7. A fixed scraper 9 is fixedly connected to the bottom of the fixed spring 8. A fan 10 is fixedly installed on the top of the fixed plate 6. A connecting air pipe 11 is fixedly connected to one side of the fan 10. A jet nozzle 12 is fixedly connected to the bottom of the connecting air pipe 11. A positioning mechanism is provided inside the fixed shell 5.

[0025] As attached Figure 1 , 2 As shown, the fixing ring 3 is rotatably connected to the diamond grinding wheel body 1. The number of fixing ring 3 and connecting plate 4 is set to two, so that the fixing ring 3, connecting plate 4 and fixing shell 5 will not rotate with the diamond grinding wheel body 1, thereby avoiding the fixing shell 5 from affecting the cutting process.

[0026] As attached Figure 1-3 As shown, one end of the jet nozzle 12 penetrates through the fixed shell 5 and extends into the interior of the fixed shell 5. The cross-sectional shape of the fixed shell 5 is set to be arc-shaped to facilitate jet cleaning of impurities on the diamond grinding wheel body 1.

[0027] As attached Figure 4 As shown, the positioning mechanism includes a fixing block 14, and the number of fixing blocks 14 is set to multiple. The multiple fixing blocks 14 are evenly fixed on both sides of the inner wall of the fixing shell 5. The multiple fixing blocks 14 are rotatably connected to the ball bearings 15. The ball bearings 15 are in contact with the surface of the diamond grinding wheel body 1, which plays a positioning role for the diamond grinding wheel body 1, reduces the error caused by vibration, and ensures the cutting accuracy of the diamond grinding wheel body 1.

[0028] As attached Figure 3 , 5 As shown, the fixing spring 8 is made of carbon steel, the bottom of the fixing plate 6 passes through the fixing shell 5 and extends into the interior of the fixing shell 5, and the fixing scraper 9 is slidably connected to the groove 7 to ensure the service life of the fixing spring 8 and facilitate the rebound force to make the fixing scraper 9 press against the diamond grinding wheel body 1 for cleaning.

[0029] The working principle of this utility model is as follows: First, the diamond grinding wheel body 1 is fixed on the grinding machine spindle by the mounting bushing 2. The grinding machine spindle drives the diamond grinding wheel body 1 to rotate at high speed to perform grinding on the workpiece. During the rotation of the diamond grinding wheel body 1, the positioning mechanism plays a key limiting role. When the diamond grinding wheel body 1 rotates at high speed, the ball 15 rolls accordingly, forming a circumferential limit on the diamond grinding wheel body 1, effectively limiting its radial runout, and ensuring that the diamond grinding wheel body 1 always rotates stably around the set axis, providing a basic guarantee for high-precision grinding.

[0030] Simultaneously, the cleaning mechanism operates to remove impurities from the surface of the diamond grinding wheel body 1. The fixed shell 5, fixed to the top of the connecting plate 4, has an arc-shaped structure. The bottom of the fixed plate 6 extends into the interior of the fixed shell 5. The fixed spring 8, made of carbon steel, in the groove 7 at the bottom of the fixed plate 6 applies elastic pressure to the fixed scraper 9, ensuring close contact between the fixed scraper 9 and the surface of the high-speed rotating diamond grinding wheel body 1. The fixed scraper 9 can slide within the groove 7 to adapt to minute changes in the grinding wheel surface. During the rotation of the diamond grinding wheel body 1, the fixed scraper 9 scrapes away dirt, debris, and other impurities adhering to its surface. In addition, the fan 10 at the top of the fixed plate 6 generates a high-speed airflow, which passes through... The air supply is delivered to the air nozzle 12 via the connecting pipe 11. One end of the air nozzle 12 extends into the interior of the fixed housing 5 and is aligned with the surface of the diamond grinding wheel body 1. It thoroughly blows away any small impurities or loose debris remaining after the scraper has removed the material, ensuring that the diamond abrasive grains on the surface of the diamond grinding wheel body 1 always maintain a clear cutting edge. This prevents impurities from clogging or interfering with the grinding process. The limiting effect of the ball bearing 15 ensures the stability of the rotation of the diamond grinding wheel body 1. Combined with the scraping action of the fixed scraper 9 and the blowing action of the air nozzle 12, the surface of the grinding wheel remains clean. The synergistic effect of the two significantly reduces grinding errors caused by vibration and impurities, thereby effectively improving the grinding accuracy of the flat grinding diamond grinding wheel.

[0031] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
