Description

TECHNICAL FIELD

[0001] The utility model belongs to diamond processing technical field, especially relate to a batch cutting CVD synthetic diamond's frock. BACKGROUND

[0002] Diamond is a kind of material with high carrier mobility, high thermal conductivity, low thermal expansion coefficient, and also has good chemical stability and biological compatibility, and is widely used in various fields.Diamond is the hardest mineral material, and when cutting and processing by conventional mechanical method, there are often problems of low efficiency and serious material wear.

[0003] Laser cutting energy is concentrated, and the directionality is single, and the efficiency and accuracy of processing are considered, which is a common cutting method in diamond processing.In the process of laser cutting of diamond, an adhesive is usually used to load and fix the diamond, and the adhesive used for laser cutting needs to be cleaned with a special chemical reagent, and the residue of the adhesive or chemical reagent may affect the further use of the diamond, so a clamp for clamping single crystal diamond sheet is needed.

[0004] The Chinese utility model patent with the authorization announcement number CN221270061 U and the authorization announcement date of 2024.07.05 discloses a negative pressure sample placing table applied to diamond laser cutting, which comprises a base, a sample placing block, a sample fixing position provided on the sample placing block, a sample suction hole provided on the sample fixing position, an air suction hole provided on the side edge of the sample placing block, a negative pressure cavity provided in the interior of the sample placing block, and the air suction hole and the sample suction hole are communicated through the negative pressure cavity.The negative pressure sample placing table can fix the diamond sample to be laser cut by the negative pressure adsorption mode.

[0005] However, the negative pressure sample placing table needs to adsorb all the diamonds on each sample suction hole before cutting, and if there is no diamond to be cut on the sample suction hole, the exposed sample suction hole will make the negative pressure cavity communicate with the external air pressure, resulting in poor negative pressure effect of the negative pressure cavity, poor adsorption effect and unstable cutting and fixing of the diamond, which affects the cutting quality and effect. UTILITY MODEL CONTENT

[0006] The utility model aims at the above-mentioned technical problems, and provides a batch cutting CVD synthetic diamond's frock, which can ensure the negative pressure adsorption effect when cutting in non-full station and ensure the cutting quality.

[0018] In the technical solution, normally, the fixed nut is always connected with the threaded hole and does not move, when it is needed to block the negative pressure cavity and the sample suction hole, only the switching stud in the fixed nut needs to be screwed, so that the switching stud covers the sample suction hole, each operation only adjusts the switching stud, and the fixed nut directly connected with the sample seat is not adjusted, through the split setting of the bolt assembly, the threaded hole on the tooling can be protected, only the threads in the switching stud and the fixed nut hole are consumed, replacement is convenient when failure, and the service life of the tooling is improved.

[0019] Further, the two air extraction holes are arranged at two ends of the sample seat.

[0020] In the technical solution, the two air extraction holes can improve the efficiency of negative pressure extraction.

[0021] Further, the negative pressure cavity comprises:

[0022] The first long hole extends along the length direction of the sample seat, and the two ends of the first long hole are respectively communicated with the air extraction holes on the two sides of the sample seat;

[0023] The threaded hole is perpendicular to the first long hole, and the switching stud and the threaded hole have an air gap.

[0028] Further, four sample suction holes are arranged on each fixed position, the adsorption area is large, and the stability of adsorption is ensured.

[0029] The beneficial effects of the utility model are:

[0030] 1. When normally used, the sample suction holes on all fixed positions are communicated with the negative pressure cavity, and each fixed position can adsorb diamond for cutting, when it is not needed to place diamond on each fixed position, such as when the number of diamond is not enough or the volume of diamond is too large and diamond can only be placed at intervals, the sample suction holes on the corresponding vacant fixed positions should not be communicated with the negative pressure cavity, so that the negative pressure state of the negative pressure cavity is stable, the effect of negative pressure adsorption is ensured, and the cutting quality is ensured.

[0031] 2. The bolt assembly is arranged in two parts, the threaded hole on the tool is protected, only the threads of the switching stud and the fixed nut inner hole are consumed, the tool service life is improved.
