TECHNICAL FIELD
[0001] The utility model relates to a crystal grinding and polishing clamp and belongs to the technical field of crystal processing equipment. BACKGROUND
[0002] Non-natural crystal (also known as water diamond, glass crystal) is generally processed by grinding and polishing the crystal blank to obtain a crystal cutting surface. The existing crystal processing equipment can realize semi-automatic batch grinding and polishing. A general crystal grinding and polishing clamp is used to grind and polish the crystal blank by sticking it to the clamp pin of the through hole with rosin. After grinding and polishing at a certain angle, the clamp pin is rotated by a certain angle by the rotating device of the clamp to continue grinding and polishing, and this cycle is required for the cutting surface.
[0003] The existing crystal grinding and polishing clamp is generally composed of a turbine pin, a clamp body, and a transmission assembly (usually a screw rod linkage). The clamp body is fixed with the grinding and polishing equipment. After the grinding and polishing of all the crystals in the same clamp is completed, the clamp slides away from the equipment tooling, and another clamp with a crystal stuck to it is replaced for grinding and polishing. When the clamp slides into or slides away from the designated working position of the grinding and polishing equipment, the clamp body is prone to wear due to friction with the equipment, which may cause gaps, deviations, and shaking in the clamp, affecting the grinding and polishing quality. If the wear is severe, the entire clamp may be scrapped. The polishing grinder is provided on one side of the turbine pin, and the grinding wheel of the polishing grinder is positioned on one side of the positioning hole at the top of the turbine pin. When the turbine pin rotates to drive the crystal to rotate, the grinding wheel of the polishing grinder grinds and polishes the crystal. Under long-term high-pressure working conditions, the turbine pin may shake and have a low service life. The main reason is that the clamp body is made of aluminum, and the turbine pin is arranged in the movable groove in the clamp body. When the force on one side of the grinding wheel is greater than the force on the aluminum body of the movable groove, the movable groove on the clamp aluminum body will become larger, causing the turbine pin to shake and become unusable. Therefore, there is an urgent need for a component that tightly fits the movable groove to prolong the service life of the clamp. SUMMARY
