Problems solved by technology
[0004] During the grinding process where the grinding head and the sapphire crystal cooperate with each other, high temperatures are often generated, which can easily cause damage to the grinding head and affect the quality of the grinding accuracy. Therefore, good cooling is very necessary for the grinding operation, but the above-mentioned sapphire crystal precision grinding device The upper end of the machine is an ultrasonic grinding mechanism. Combining traditional grinding and ultrasonic grinding, it is impossible to install an additional cooling device on the basis of its structure. At the same time, the lower end of the fixed table is equipped with multiple installation parts. Multiple products are ground at the same time. The external cooling device cannot be satisfied at the same time. Reliable cooling of multiple products

A sapphire crystal precision grinding device. It is characterized in that: the grinding action mechanism is installed on the frame, including the ultrasonic rotating main shaft, the driving wheel group and several fixtures, the ultrasonic rotating main shaft is connected with the driving wheel group, the fixtures are evenly distributed on the driving wheel group in the circumferential direction, and can rotate with the driving wheel group Revolving action; the atomizing mechanism is correspondingly arranged above the grinding action mechanism. The atomizing mechanism slides up and down with the frame and is connected with a lifting mechanism that drives it to move up and down. A polishing pad is installed at the bottom of the atomizing mechanism. The advantage is that while ensuring high-efficiency and high-quality grinding, it can also ensure a reliable cooling effect.
Description
technical field [0001] The invention relates to the technical field of grinding processing, in particular to a sapphire crystal precision grinding device. Background technique [0002] Sapphire crystal has the characteristics of stable chemical properties, high hardness, and good transmittance. It is widely used in mobile phone screens and various high-precision instruments, which puts forward higher requirements for the ultra-smooth and non-damaging surface of sapphire crystal. [0003] For example, the Chinese invention patent application (CN 108788945 A) discloses a sapphire crystal precision grinding device, which includes an ultrasonic grinding mechanism and a fixed table. The ultrasonic grinding mechanism is correspondingly installed above the fixed table. The grinding head is driven by the main shaft to rotate and revolve around the main shaft. Cooperating with ultrasonic vibration, the traditional grinding and ultrasonic theory are combined to greatly improve the gri...
