Description

Technical Field

[0001] The present invention relates to the technical field of cutting fixtures, and in particular to a rough stone cutting fixture and a use method thereof. Background Art

[0002] In the process of preparing artificial diamonds using MPCVD, or chemical vapor deposition, repeated growth is required. During each growth process, polycrystals will appear on the surface and around the original stone. The appearance of polycrystals will cause the quality of the original stone to deteriorate. Therefore, when polycrystals appear again, their surface needs to be cut cleanly to facilitate the next stage of growth. Laser cutting is currently the most practical and economical cutting method.

[0003] Laser cutting is a non-contact processing. During the processing, the workpiece is not subjected to force in any direction. Laser cutting uses a focused high-power, high-energy density laser beam to irradiate the raw stone to be processed, so that the irradiated raw stone is quickly melted and vaporized, and at the same time, the ablated material is quickly blown away with the help of a high-speed airflow coaxial with the light beam, thereby cutting the raw stone. However, in the vertical cutting process from top to bottom, the cut surface of the raw stone will present a "V-shaped" incision, and the upper incision will be much larger than the lower one, resulting in uneven thickness of the raw stone after cutting. At the same time, the cutting loss gradually increases. The traditional fixture can only stably clamp the raw stone, and cannot adjust the cutting angle of the raw stone according to cutting needs, further reducing the functionality of the raw stone processing.

[0004] Therefore, in view of the problem that the above-mentioned traditional rough stone clamp can only stably clamp the rough stone, but cannot adjust the cutting angle of the rough stone according to the cutting needs, resulting in uneven thickness of the rough stone after cutting, and the cutting loss gradually increases, a rough stone cutting clamp that can adjust the cutting inclination angle can be designed to solve the problem of "V-shaped" incision in the current cutting process. Summary of the invention

[0005] In order to overcome the problem that traditional rough stone clamps can only hold the rough stone stably but cannot adjust the cutting angle of the rough stone according to cutting needs, the cutting surface will present a "V-shaped" cut during the laser cutting of the rough stone, which will cause the rough stone to have uneven thickness after cutting.

A rough stone cutting fixture and a method of using the same, characterized in that It comprises a rough stone cutting fixture according to claims 1-7, and the steps are as follows; Step 1: Paste the raw stones in the pasting grooves (703) at equal distances, then place the material base plate (7) on the support plate (603), insert the positioning rod (701) into the positioning hole (604), and at the same time, the magnetic suction block (702) can be sucked into the magnetic suction groove (605), so that the material base plate (7) can be stably fixed on the fixture motherboard (6); Step 2: Start the control motor (502), adjust the screw rod (503) to drive the screw rod slider (504) to rotate, so that the raw stone can be transported to the bottom of the laser cutting device (8) for loading and cutting, start the laser cutting device (8), and the laser is irradiated vertically from above the raw stone, forming a "V-shaped" incision during the cutting process; Step 3: Start the servo motor (403), the driving pulley (405) can drive the belt (406) to rotate, so that the driven pulley (407) drives the rotating crossbar (408) to rotate, and at the same time the locking gear (409) can drive the matching gear (410) to rotate synchronously, so that the limit rotating block (412) on the adjustment position rotating rod (411) can drive the clamp motherboard (6) to tilt slightly, so that its tilt angle is kept horizontal with the "V-shaped" incision angle, and when the side edge line of the clamp motherboard (6) completely coincides with the laser cutting line of the laser cutting device (8), the angle adjuster (4) can be stopped to start the cutting program; Step 4: When it is necessary to cut other parts of the original stone after the cutting is completed, start the rotating motor (301) so that the rotating vertical rod (302) can drive the bottom turntable (303) to rotate, and the limit slider (306) slides in the limit slide groove (305), which serves the purpose of guiding the limit adjustment, and can further drive the original stone to rotate, and repeat the procedure of step 3 to perform uniform cutting at multiple positions.
