Description

Technical Field

[0001] The invention relates to the field of optical component processing, in particular to a plane polishing device for an optical crystal component and a polishing process thereof. Background Art

[0002] Optical crystals are crystal materials used as optical medium materials. They are mainly used to make windows, lenses and prisms in the ultraviolet and infrared regions. Plane polishing is a key step in the manufacturing process of optical crystal components. The traditional plane polishing of optical crystal components is to first place a carrier ring on the upper surface of the polishing disk and fix or connect it to the swing arm. Then, the workpiece is held and placed in the carrier ring with the bottom surface in contact with the polishing disk. The workpiece is limited by the carrier ring or other limiting devices. Then, a pressure block is placed in the carrier ring to squeeze the workpiece to increase the pressure between the polishing surface of the workpiece and the surface of the polishing disk. Then, a swing motor is used to drive the swing arm carrier ring and the workpiece to make relative circular motion to achieve efficient polishing.

[0003] The polishing process of optical components includes pretreatment process, grinding process and polishing process. The polishing process is further divided into coarse polishing, medium polishing and fine polishing. During polishing, polishing pastes with higher mesh numbers are replaced step by step as needed. Polishing liquid needs to be sprayed on the polishing surface during polishing. The higher the content of polishing powder in the polishing liquid, the higher the polishing efficiency. The lower the content of polishing powder, the lower the polishing efficiency.

[0004] Existing grinding equipment can only spray polishing liquid from one side of the carrier ring or directly on the surface of the polishing disk. The polishing disk needs to rotate one or more circles before a small amount of polishing liquid can adhere to the polishing surface of the workpiece. It cannot adhere to the polishing surface of the workpiece in time, which may cause scratches on the polishing surface or low grinding efficiency, ultimately affecting the quality of grinding and polishing. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a planar polishing device for optical crystal components and a polishing process thereof to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a plane polishing device for optical crystal components, comprising a polishing device body and a swing arm, wherein the upper surface of the swing arm is fixedly connected to a fixing frame, an adjusting component is fixedly installed on the inner wall of the top end of the fixing frame, and a lowering component is threadedly installed on one end of the adjusting component away from the swing arm;
