Description

Technical Field

[0001] The utility model relates to the field of diamond processing, in particular to a polishing device for diamond crystals. Background Art

[0002] Diamond is a mineral composed of carbon. After processing, the surface of diamond is relatively rough. During the drill bit processing or sintering process, the rough surface of the diamond will produce slight carbonization and cause loss. Therefore, the rough surface of the diamond needs to be polished to make it smooth.

[0003] Due to the brittle nature of diamond crystals, most diamond crystals remain in an irregular shape. Traditionally, diamond crystals are clamped using a two-finger gripper. However, since the two-finger gripper can only fix the two sides of the diamond, when polishing certain irregularly shaped diamonds, the diamond crystals are prone to flip and deflect during the polishing process, and even cause the diamond to fall off. Therefore, a diamond crystal polishing device is proposed to solve the above problem. Utility Model Content

[0029] In this embodiment, in actual use, the start-up of the second motor 91 will drive the left and right screw rods 92 to rotate in the protective box 8. The rotation of the left and right screw rods 92 will cause the two transmission blocks 93 to drive the two clamps 10 to move toward each other, thereby adjusting the distance between the two clamps 10, making it easier for the pressure plate 13 to contact the diamond. The second motor 91 has its own power supply to prevent the line from being entangled.

[0030] A rotation groove is provided inside the protection box 8 , a fixing ring 14 is fixedly connected to the right side of the mounting plate 6 , and a slip ring 15 slidably connected to the rotation groove is fixedly connected to the right side of the fixing ring 14 .

At this time, the slip ring 15 connected to the fixed ring 14 will slide in the rotating groove, and the rotating groove provides rotation space and direction for the rotation of the slip ring 15.

[0032] The plurality of bolts 11 are all located at the same horizontal plane, and protective pads 16 are disposed on the outer sides of the plurality of pressure plates 13 .
