Abstract

The invention discloses a crystal blank grinding and polishing pick device, comprising a shaft sleeve and a hollow shaft vertically arranged on the shaft sleeve. The upper end of the hollow shaft is connected with a gas pipe. A cavity is arranged under the hollow shaft. The gas pipe and the hollow shaft form an air passage to communicate with the cavity. The cavity comprises a first part on the upper part and a second part on the lower part, and a channel communicating the first part with the second part. The first part is internally provided with a compression spring and a steel ball used to block the channel. The upper end of the compression spring is abutted against the lower end of the hollow shaft. The lower end of the compression spring is abutted against the steel ball. The channel is internally provided with a needle portion whose diameter is smaller than the inner diameter of the channel, so a gap is formed between the needle portion and the inner wall of the channel. Using the above technical scheme, the device can rapidly pick up a crystal blank, and clamping is relatively firm. The device is simple in structure.

Description

technical field [0001] The invention relates to a grinding and polishing pick-up device for crystal blanks, which belongs to the technical field of crystal production process equipment. Background technique [0002] Grinding and polishing equipment is often used in the production and processing of crystals to grind and polish the crystal surface. The usual grinding and polishing equipment includes a clamping device for clamping the crystal blank, a grinding disc, and a device that drives the clamping device to rotate relative to the grinding disc. drive unit. Generally, the shape of the crystal blank is round or irregularly granular, and the clamping device for clamping the crystal blank is usually designed with a complicated structure in order to be able to hold and stabilize the crystal blank, and the crystal blank is not easy to install in the clamp. The clamping part of the holding device causes low production efficiency. Contents of the invention [0003] Therefore,...
