Technical Field

In some cases, oil needs to be added to protect the balls, but the inability to control the temperature can easily lead to low temperatures, causing the oil to solidify and compromising the milling effect. In other cases, oil is not needed, but the inability to control the temperature during milling can easily result in excessively high temperatures, damaging the balls. Utility Model Content

[0027] Reference Figure 1-3 ,

[0028] A grinding disc for grinding balls includes a lower grinding plate 1, an upper grinding plate 2, and a driving component 3. The lower grinding plate 1 forms a receiving chamber to accommodate the balls to be ground, and the upper grinding plate 2 forms a grinding surface that contacts the balls. The driving component 3 is used to move the upper grinding plate up and down and to rotate the lower grinding plate. The grinding disc also includes a power cabinet 4; both the lower and upper grinding plates are positioned above the power cabinet 4. A temperature sensor and an air injection component 5 are installed in the upper grinding plate; the temperature sensor detects the temperature of the receiving chamber; the air injection component 5 injects temperature-controlled air into the receiving chamber. The driving component 3 includes a mounting frame 31, a drive motor 32, and a drive hydraulic cylinder 33. The mounting frame 31 is fixed to the power cabinet 4, and the drive hydraulic cylinder 33 is mounted on the mounting frame 31. The output end of the drive hydraulic cylinder 33 is connected to the upper grinding disc, thereby moving the upper grinding disc up and down. The drive motor 32 is located in the power cabinet 4 and drives the lower grinding disc to rotate.

[0029] By adopting the above technical solution, the air injection component 5 injects temperature-controlled air into the receiving chamber. In this way, the air injection component 5 can better control the temperature in the receiving chamber and avoid the situation where the oil lubrication effect on the ball is poor due to the low temperature in the receiving chamber, which would result in poor grinding effect of the ball.

[0030] Specifically, the air injection component 5 includes: an air pump 51, an air injection pipe 52, and a heater; the heater is used to heat the air in the air injection pipe 52; the air pump 51 injects external air into the receiving chamber through the air injection pipe 52. This better increases the temperature of the receiving chamber, thereby avoiding the possibility of damage caused by collisions between the balls at low temperatures, and better ensuring the grinding effect. The air injection pipe 52 penetrates the upper grinding plate 2.

[0031] Specifically, the temperature sensor is used to set a preset temperature for the receiving chamber; the air injection component 5 also includes a cooler, which is used to cool the air in the air injection pipe 52; when the temperature sensor detects that the temperature in the receiving chamber is lower than the preset temperature, the heater heats the air in the air injection pipe 52; when the temperature sensor detects that the temperature in the receiving chamber is higher than the preset temperature, the cooler cools the air in the air injection pipe 52. By utilizing the coordination of the temperature sensor, cooler, and heater, the temperature in the receiving chamber can be accurately controlled, allowing the balls to be ground at a suitable temperature. This avoids excessively high temperatures affecting the ball performance and excessively low temperatures causing ball damage, thus better ensuring the grinding quality of the balls.

[0032] The heater and cooler both use existing technologies. The cooler is cooled by a cooling fan, and the heating element is heated by a heating tube or heating wire.

[0033] Specifically, a flow divider 6 is formed on the lower grinding plate 1; the air outlet direction of the air injection pipe 52 intersects with the flow divider 6. The flow divider 6 is a conical block, and the air blown on the flow divider 6 is divided, thereby allowing the air to diffuse into the receiving chamber more quickly.

[0034] Specifically, a limiting ring 7 is also provided on the lower grinding plate 1, the center of which coincides with the middle of the lower grinding plate 1; the outer part of the limiting ring 7 is used to accommodate the balls to be ground. The limiting ring 7 is used to prevent the balls from entering the middle of the upper grinding plate 2, so that components such as the air injection pipe 52 and the flow divider 6 can be set inside the limiting ring 7 to better inject air and make the air diffuse quickly.

[0035] Specifically, a connecting rod 8 is provided at the lower part of the limiting ring 7. The connecting rod 8 is used to fix the limiting ring 7 to the lower grinding plate 1 and to create a gap between the limiting ring 7 and the lower grinding plate 1. The purpose of the gap is to allow air to pass through the gap and directly contact the lower part of the ball to be ground. There is also a corresponding gap between the limiting ring 7 and the upper grinding plate 2, which facilitates faster contact between air and the ball to be ground.

[0036] Specifically, the upper grinding plate 2 is also provided with an oil inlet and an oil inlet channel; the oil inlet channel is connected to the oil inlet; the oil inlet channel is externally connected to an oil inlet pipe and an oil pump; the oil inlet is connected to the receiving chamber and is located inside the limiting ring 7. The oil pump is externally connected to an oil tank, so that the oil pump can draw oil from the oil tank outward and inject it into the oil inlet channel through the oil inlet pipe. The oil in the oil inlet channel is discharged outward at the oil inlet, discharged into the limiting ring 7, and then diffused in all directions under the centrifugal force of the rotation of the lower grinding plate 1. Then, it flows to the position of the ball to be ground at the gap and contacts the ball to be ground, thereby lubricating the ball to be ground and improving the grinding effect. Among them, the grinding of the ball is mainly polishing the ball, so the ball can be ground and polished with the assistance of lubricating oil.

[0037] Specifically, the distance between the lower end face of the limiting ring 7 and the lower grinding plate 1 is less than the radius of the ball to be ground.

[0038] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
