[0023] Embodiment 1

When in use, the roller base 1 can be connected to a power device through the connecting rod 2, so that the power device drives the roller base 1 to rotate, and the roller base 1 will grind the workpiece through the diamond particles 4 on its external working layer 3 when rotating. At the same time, during the grinding process, the diamond particles 4 and the working layer 3 can be cooled by the cooling component 5, thereby alleviating the degree of deformation of the working layer 3 due to heat, thereby improving the service life of the equipment;

[0025] The cooling component 5 includes a water storage sleeve 51 rotatably mounted on one side of the roller base 1, a water storage chamber 54 is opened inside the roller base 1, cooling protrusions 59 are installed on the roller base 1 and on both sides of the working layer 3, and the cooling protrusions 59 are provided with flushing holes 55 connected with the water storage chamber 54, and the outside of the water storage sleeve 51 is provided with a water outlet hole 52 connected with the water storage chamber 54, and one end of the water storage sleeve 51 is connected with a water inlet pipe 57. In this embodiment, through the setting of the water inlet pipe 57, the inner cavity of the water storage sleeve 51 is connected with an external water pump. When cooling, cooling water can be introduced into the water storage sleeve 51, and then the cooling water is injected into the water storage chamber 54 through the water outlet hole 52 opened on the water storage sleeve 51. Finally, the cooling water entering the water storage chamber 54 will be sprayed from the flushing hole 55 onto the working layer 3 being polished, thereby achieving cooling of the working layer 3.

[0026] The flushing hole 55 is arranged obliquely. Figure 4 As shown, the water outlet end of the inclined flushing hole 55 is aligned with the working layer 3 , and when water is discharged, the cooling water column will directly flow onto the working layer 3 , thereby improving the cooling effect of the working layer 3 .

[0027] A partition filter plate 56 is fixedly installed inside the flushing hole 55. When the working layer 3 is polished, a lot of debris will be generated. Some of the debris will easily enter the water storage chamber 54 along the flushing hole 55, polluting the cooling water quality and affecting its cooling capacity. In this embodiment, a partition filter plate 56 is provided in the flushing hole 55 to effectively prevent the debris from entering the water storage chamber 54, and the debris remaining on the partition filter plate 56 will also be washed away by the water flow.

[0028] Embodiment 2

[0029] Reference Figure 1-Figure 5 This embodiment is basically the same as the first embodiment, and is more optimized in that a one-way component 53 is provided on the inner wall of the water storage chamber 54, and the one-way component 53 includes a one-way cone groove 531 opened inside the roller base 1, and a mounting bracket 533 is provided inside the one-way cone groove 531. A one-way spring 534 is fixedly installed on one side of the mounting bracket 533, and a partition plate 532 slidably installed with the one-way cone groove 531 is fixedly installed on one end of the one-way spring 534, and a sliding rod 535 slidably connected with the mounting bracket 533 is fixedly installed on one side of the partition plate 532. When the roller base 1 rotates at a high speed, the water in the water storage chamber 54 Cooling water is easy to overflow from the connection with the water storage sleeve 51, causing a waste of cooling water. In this embodiment, the one-way component 53 is provided to reduce the overflow of cooling water and improve the utilization efficiency of cooling water. In specific operation, when the water outlet 52 corresponds to the one-way conical groove 531, the impact of the water flow will cause the partition 532 to slide, thereby opening the one-way conical groove 531, so that the cooling water can enter the water storage chamber 54. When they do not correspond, under the action of the water pressure inside the water storage chamber 54 and the elastic force of the one-way spring 534, the partition 532 will automatically close the one-way conical groove 531 to prevent the cooling water from flowing out.

[0030] A protective baffle 58 is provided on the upper part of the water inlet pipe 57. The provision of the protective baffle 58 can prevent the cooling water pipe connected to the water inlet pipe 57 from directly contacting the high-speed rotating connecting rod 2, thereby protecting the cooling water pipe.

[0031] Both the water inlet pipe 57 and one end of the connecting rod 2 are provided with a connecting flange, and a limiting groove is provided inside the connecting flange. The setting of the limiting groove inside the connecting flange plays a role in limiting and guiding the flange connected to the water inlet pipe 57 and the connecting rod 2, avoiding the probability of loosening and improving the stability of the connection.

[0032] How it works

[0033] When in use, the roller base 1 can be connected to the power equipment through the connecting rod 2, so that the power equipment drives the roller base 1 to rotate. When the roller base 1 rotates, the diamond particles 4 on its external working layer 3 will grind the workpiece. At the same time, during the grinding process, the cooling component 5 can be used to cool the diamond particles 4 and the working layer 3, thereby alleviating the degree of deformation of the working layer 3 due to heat and improving the service life of the equipment. In this embodiment, the inner cavity of the water storage sleeve 51 is connected to the external water pump through the setting of the water inlet pipe 57. When cooling, the cooling water can be introduced into the water storage sleeve 51, and then the cooling water is injected into the water storage chamber 54 through the water outlet hole 52 provided on the water storage sleeve 51. Finally, the cooling water entering the water storage chamber 54 will be sprayed from the flushing hole 55 onto the working layer 3 being ground, thereby achieving the cooling of the working layer 3. In addition, if Figure 4 As shown, the water outlet end of the inclined flushing hole 55 is aligned with the working layer 3. When the water is discharged, the cooling water column will directly flow onto the working layer 3, thereby improving the cooling effect of the working layer 3. At the same time, since a lot of debris will be generated when the working layer 3 is polished, some of the debris will easily enter the water storage chamber 54 along the flushing hole 55, polluting the water quality of the cooling water and affecting its cooling capacity. In this embodiment, a partition filter plate 56 is provided in the flushing hole 55 to effectively prevent the debris from entering the water storage chamber 54, and the debris left on the partition filter plate 56 will also be washed away by the water flow. Moreover, during the high-speed rotation of the roller base 1, the cooling water in the water storage chamber 54 is easy to overflow from the connection with the water storage sleeve 51, resulting in a waste of cooling water. In this embodiment, the one-way component 53 is set to reduce the overflow of cooling water and improve the utilization efficiency of cooling water. In specific operation, when the water outlet 52 corresponds to the one-way cone groove 531, the impact of the water flow will cause the partition 532 to slide, thereby opening the one-way cone groove 531, so that the cooling water can enter the water storage chamber 54. When it does not correspond, under the action of the water pressure inside the water storage chamber 54 and the elastic force of the one-way spring 534, the partition 532 will automatically close the one-way cone groove 531 to prevent the cooling water from flowing out. In addition, the setting of the protective partition 58 can prevent the cooling water pipe connected to the water inlet pipe 57 from directly contacting the high-speed rotating connecting rod 2, thereby protecting the cooling water pipe.
