Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting, and in particular relates to a laser cutting device. Background Art

[0002] Large single crystal diamond is the rough stone of diamond, and is the hardest substance naturally existing in nature. With the increase in the demand for diamond, the technology of artificially generating large single crystal diamond or diamond is becoming more and more mature, such as static high pressure method, vapor deposition technology (CVD), etc. In order to process large single crystal diamond into diamond, it is necessary to cut the diamond, i.e. the diamond blank, and then perform rough grinding, fine grinding and other processes. The traditional method of cutting diamond adopts contact processing, which causes greater wear on the grinding wheel and grinding disc, and generates a lot of dust, which is harmful to the health of the processing personnel.

[0003] With the development of laser cutting technology, the existing diamond blank cutting mostly adopts laser galvanometer technology, that is, the diamond blank is cut by the laser emitted by the laser galvanometer module, such as the Chinese invention patent with application number 201510909003.1 discloses a laser engraving machine. In the prior art, when cutting the diamond blank, the diamond blank needs to be bonded to the fixing rod by adhesive, and then the fixing rod is fixedly inserted into the installation fixture, and then the installation fixture is fixed on the machine table, and the laser galvanometer module is used to laser cut the batch of diamond blanks.

The adjustment fixture can be used to clamp diamonds and is used in laser diamond cutting, belonging to the technical field of laser diamond cutting.

[0005] The above-mentioned prior art has the following technical problems: 1. Since the above-mentioned diamond laser cutting fixture is manually adjusted, when the bonding accuracy error of the diamond blank is large or the diamond blank needs to be cut into various shapes or even special shapes, the angle of the diamond blank cannot be automatically adjusted; 2. When the pressing block with the diamond blank fixed to the base block in the above-mentioned prior art is fixed, multiple bolts need to be locked, which leads to low clamping efficiency of the diamond blank.
