Description

Technical Field

[0001] This utility model relates to the field of grinding disc technology, specifically a grinding disc with a water cooling system. Background Technology

[0002] A grinding disc is a carrier used to apply or embed abrasives, enabling the abrasive grains to perform cutting action. It also serves as a tool for shaping the grinding surface. During operation, the grinding disc generates a large amount of heat due to the friction and cutting action of the abrasive material. If this heat cannot be dissipated in time, the temperature of the grinding disc will rise, thus affecting the grinding effect and product quality. The role of the water cooling system is to remove the heat generated during the grinding process by circulating cooling water, thereby effectively controlling the temperature of the grinding disc.

[0003] When existing grinding discs grind parts, the friction between them and the product generates a lot of heat, causing the product to heat up. Generally, grinding and polishing machines rely on the circulation of grinding fluid and natural heat dissipation to remove the heat. However, the product temperature will be very high during processing. Thermal expansion and contraction will reduce the processing accuracy of the product. Some product materials need to be kept at a specific temperature, which will affect the quality and performance of the product.

[0004] To address these issues, this invention provides a grinding disc with a water-cooling system. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grinding disc with a water-cooling system, which solves the problem that the product temperature is too high during processing with the existing grinding discs, and thermal expansion and contraction will reduce the processing accuracy of the product.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a grinding disc with a water cooling system, including a grinding disc, a main shaft is provided at the bottom of the grinding disc, a cold water chamber is provided inside the grinding disc, a cold water circulation channel is provided inside the main shaft, and a cleaning component is provided on the right side of the grinding disc.

[0007] Preferably, the cleaning assembly includes a support plate disposed on the right side of the grinding disc. A mounting frame is fixedly connected to the front side of the support plate. A rotating shaft is rotatably connected inside the mounting frame. A worm gear is fixedly connected to the front end of the rotating shaft. An outer frame is fixedly connected to the middle of the rotating shaft. A brush plate is slidably connected inside the outer frame. Multiple springs are disposed inside the outer frame. A worm is meshed with the top of the worm gear.

[0008] Preferably, the cold water chamber and the cold water circulation channel are connected.

[0009] Preferably, the outer side of the rotating shaft is rotatably connected inside the support plate.

[0010] Preferably, the worm gear is rotatably connected to the inside of the mounting frame.

[0011] Preferably, one end of the spring is fixedly connected to the inner wall of the outer frame, and the other end of the spring is fixedly connected to the inner side of the brush plate.

[0012] Preferably, the brush plate abuts against the top of the grinding disc.

[0013] Preferably, a handwheel is fixedly connected to one end of the worm gear.

[0014] Beneficial effects

[0015] This invention provides a grinding disc with a water-cooling system. Compared with the prior art, it has the following advantages:

[0016] (1) The grinding disc with water cooling system adds a cold water chamber and a cold water circulation system to the grinding disc and the spindle respectively, so that the low temperature water circulates in the middle of the grinding disc to remove the heat of the product being processed on the grinding disc, keeping the product at a low temperature during processing, avoiding the product temperature from being too high during processing, and the thermal expansion and contraction will reduce the processing accuracy of the product, thereby improving the quality and performance of the product.

[0017] (2) The grinding disc with water cooling system is driven to rotate by the main shaft. Then, the brush plate comes into contact with the grinding disc, so that the brush plate cleans the impurities attached to the grinding disc and avoids the impurities remaining on the grinding disc. At the same time, the handwheel is turned to drive the worm gear to rotate, and the worm gear drives the worm wheel, which in turn drives the rotating shaft and the brush plate to rotate synchronously and adjust to a suitable angle, thereby avoiding affecting the grinding work.

[0024] 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.

[0025] Example 1:

[0026] Please see Figure 1-3 A grinding disc with a water cooling system includes a grinding disc 1, a main shaft 2 at the bottom of the grinding disc 1, a cold water chamber 3 inside the grinding disc 1, a cold water circulation channel 4 inside the main shaft 2, a cleaning component on the right side of the grinding disc 1, and the cold water chamber 3 and the cold water circulation channel 4 are connected.

[0027] Specifically, the grinding disc 1 is a key component that directly contacts the product to be ground and performs the grinding operation. A spindle 2 is located at its bottom, providing crucial support and drive for the grinding disc 1. During grinding, the spindle 2 provides stable rotational power to the grinding disc 1, ensuring that the grinding disc 1 can grind the product at an appropriate speed and force. The spindle 2 is mounted on the grinding machine. A cold water chamber 3 is located inside the grinding disc 1. The cold water chamber 3 is a key component of the water cooling system, its main function being to provide a space for the containment and circulation of low-temperature water. When the water cooling system is activated, the low-temperature water flows through the cold water chamber 3. The flow of water, through heat exchange with the inner wall of the grinding disc 1, removes the heat generated by the grinding disc 1 during the grinding process. This process effectively controls the temperature of the grinding disc 1, preventing the product from overheating due to the accumulation of heat generated during grinding, which in turn affects the processing accuracy and quality of the product. The spindle 2 has a cold water circulation channel 4 inside, which plays an important role in providing a circulation path for low-temperature water. It is connected to the cold water chamber 3 inside the grinding disc 1, so that low-temperature water can flow smoothly from the cold water circulation channel 4 into the cold water chamber 3, and then flow back from the cold water chamber 3 to the cold water circulation channel 4, forming a complete circulation system.

[0028] Example 2:

[0029] Please see Figure 1 , Figure 4 and Figure 5This embodiment provides a technical solution based on embodiment one: the cleaning component includes a support plate 5, the support plate 5 is disposed on the right side of the grinding disc 1, the front side of the support plate 5 is fixedly connected to an installation frame 6, the installation frame 6 is rotatably connected to a rotating shaft 7, the front end of the rotating shaft 7 is fixedly connected to a worm gear 8, the middle part of the rotating shaft 7 is fixedly connected to an outer frame 9, the outer frame 9 is slidably connected to a brush plate 10, the outer frame 9 is provided with multiple springs 11, and the top of the worm gear 8 is meshed with a worm 12.

[0030] The outer side of the rotating shaft 7 is rotatably connected to the inside of the support plate 5, the outer side of the worm gear 12 is rotatably connected to the inside of the mounting frame 6, one end of the spring 11 is fixedly connected to the inner wall of the outer frame 9, and the other end of the spring 11 is fixedly connected to the inner side of the brush plate 10. The brush plate 10 abuts against the top of the grinding disc 1, and one end of the worm gear 12 is fixedly connected to a handwheel 13.

[0031] Specifically, the support plate 5 is located on the right side of the grinding disc 1 and is installed on the grinding machine. It provides a stable support base for the entire cleaning assembly, ensuring that the entire cleaning assembly remains stable during operation and does not shake or shift, thereby ensuring that the cleaning work can be carried out accurately. The mounting frame 6 is a frame structure that accommodates and fixes other components. Its internal space provides a suitable installation position for components such as the rotating shaft 7 and the worm gear 8. The rotating shaft 7, as a rotating hub, undertakes the important task of connecting and transmitting power. Its rotation can drive the worm gear 8 and the outer frame 9 in the middle to rotate. The worm gear 8 drives the rotating shaft 7 to rotate. When the worm 12 rotates, due to its meshing relationship with the worm gear 8, it can convert the power transmitted from the worm 12 and transmit it to the rotating shaft 7. The outer frame 9 provides a sliding frame structure for the brush plate 10. The brush plate 10 is the component that directly contacts the top of the grinding disc 1 and cleans impurities. The spring 11 plays a role in elastic support and compensation. When the brush plate 10 wears during operation, under the action of the elastic force of the spring 11, the brush plate 10 can still be tightly attached to the surface of the grinding disc 1. The worm 12, as part of the power input, has a handwheel 13 fixedly connected to one end. When the handwheel 13 is turned, the worm 12 can be driven to rotate, thereby starting the power transmission process of the entire cleaning assembly. The handwheel 13 provides a convenient operating position for the operator.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, the chiller is first connected to one end of the chilled water circulation channel 4 inside the spindle 2. The chiller pressurizes the water so that the low-temperature water enters the chilled water chamber 3 inside the grinding disc 1 through the chilled water circulation channel 4. The water circulates in the middle of the grinding disc 1 to remove the heat from the product being processed on the grinding disc 1, keeping the product at a low temperature during processing. The low-temperature water after circulation is discharged through the other end of the chilled water circulation channel 4.

[0034] To prevent excessive accumulation of impurities on the surface of the grinding disc 1, which could lead to an uneven grinding surface or affect grinding accuracy, the grinding disc 1 is rotated by the spindle 2. Since the grinding disc 1 and the brush plate 10 are in contact, impurities adhering to the surface of the grinding disc 1 are cleaned off. When the brush plate 10 wears down, the elastic force of the spring 11 ensures that the brush plate 10 remains firmly attached to the surface of the grinding disc 1. When cleaning is no longer needed, the worm gear 12 is rotated by turning the handwheel 13. The worm gear 12 drives the worm wheel 8, which in turn drives the rotating shaft 7 and the outer frame 9 to rotate synchronously until the appropriate angle is reached. This prevents the brush plate 10 from interfering with the grinding process during operation of the grinding disc 1.
