Technical Field
[0001] This utility model relates to the field of jewelry processing technology, specifically to a gemstone grinding and cutting machine. Background Technology
[0002] Gemstones are an important part of jewelry. Before production, most gemstone raw materials are irregular stones that need to be processed into suitable shapes. This requires a grinding and cutting mechanism. Existing gemstone grinding and cutting mechanisms simply clamp the stones and then grind them. When grinding other angles or positions, the stones need to be clamped again, which is a cumbersome, time-consuming, and labor-intensive process that does not meet production needs. Utility Model Content
[0003] The purpose of this invention is to solve the problem that existing gemstone grinding and cutting mechanisms simply clamp the gemstone before grinding, but when grinding other angles or positions, they need to be clamped again, which is cumbersome, time-consuming, and labor-intensive, and does not meet production needs.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:

One end of the sliding rod is fixedly connected to a clamping sleeve facing the grinding disc. A clamping head is detachably connected to the end of the clamping sleeve. A return spring is provided between the clamping sleeve and the fixed sleeve. The return spring is fitted onto the sliding rod between the clamping sleeve and the fixed sleeve. The other end of the sliding rod extends out of the fixed sleeve and is fixedly connected to an angle indicator disc. An angle indicator scale is provided on the outer peripheral wall of the angle indicator disc. Several angle indicator slots are provided on the side of the angle indicator disc facing the fixed sleeve corresponding to the angle indicator scale.

[0037] The working principle of this utility model is as follows: In use, select the appropriate clamping head as needed, clamp the gemstone at the end of the clamping head, rotate the rotating table to rotate the clamping sleeve towards the grinding wheel inside the grinding disc. The radius of rotation can be determined according to the radius indication scale on the radius limit indicator. When the desired position is reached, lock the limit block, which abuts against the radius pointer. If the limit block is insufficient, the radius pointer can be limited by rotating the limit screw. When adjusting other surfaces or angles, pull back the clamping sleeve, the sliding rod moves backward within the fixed sleeve, and the angle indicator moves away from the angle pointer. Rotate the clamping sleeve to the corresponding position; the amount of rotation can be determined according to the angle indication scale on the angle indicator. Then release the clamping sleeve; due to the action of the return spring, the sliding rod moves back to... Previously, the angle pointer's locking mechanism would engage with the angle indicator slot on the angle indicator dial, limiting rotation during processing. By unscrewing the horizontal adjustment knob, the entire horizontal adjustment sleeve would rotate, causing the entire clamping assembly to rotate as well. The rotation position could be determined by the horizontal adjustment indicator scale on the outer wall of the horizontal adjustment sleeve. Afterward, tighten the horizontal adjustment knob to fix the position. The overall height could be adjusted by unscrewing the lifting adjustment knob to lower the horizontal adjustment indicator platform to the corresponding position, then tightening the lifting adjustment knob to fix it. Then, unscrew the horizontal adjustment knob again, lowering the horizontal adjustment sleeve onto the horizontal adjustment indicator platform, and tightening the horizontal adjustment knob to fix it. Afterward, the grinding wheel would be started to grind the gemstone. The angle grinding of different surfaces could be adjusted accordingly using the above method.
