A precision numerical control multi-station gemstone rolling and grinding machine

Abstract

The invention discloses a precision digitally-controlled multi-station precious stone barreling molding machine, which comprises a grinding system and a driving system, wherein the grinding system comprises grinding heads; each grinding head consists of a tool advancing moving mechanism, an angle tilting mechanism, an angle turning mechanism, an elevating mechanism and a pneumatic mechanism; each tool advancing moving mechanism is arranged on a grinding head tool advancing guide rail; each grinding head tool advancing guide rail is assembled together with a horizontal linear guide rail through a grinding head seat; each horizontal linear guide rail is assembled together with an upright post guide rail; the grinding heads are assembled together with an elevating upright post guide rail; and each angle tilting mechanism and each angle turning mechanism are arranged on a supporting seat, and are used for completing an angle tilting action and an angle turning action on an aluminum bar. The precision digitally-controlled multi-station precious stone barreling molding machine is characterized in that the grinding system further comprises a grinding roller; the grinding roller is arranged in parallel with the aluminum bar along the axial direction, and is connected with the driving system; at least three groups of grinding heads are arranged; each group of grinding heads is equally arranged on the outer side of the circumference of the grinding roller; and the aluminum bar is matched with the grinding roller. The barreling molding machine has the advantages of uniform grinding amount, consistent sizes of ground finished precious stones, high grinding quality and high yield.

AI Technical Summary

Problems solved by technology

This kind of molding machine that grinds gemstones through a turntable, because when the turntable rotates, the linear speeds of the inner and outer rings of the turntable are different, the linear speed of the inner ring is small, and the linear speed of the outer ring is large, resulting in different positions of the aluminum row. The grinding amount of the gemstones is inconsistent, the grinding amount of the gemstones near the inner ring of the turntable is small, and the grinding amount of the gemstones near the outer ring is large, resulting in different sizes of the finished gemstones; during the rotation of the turntable, there is a phenomenon of jumping up and down for the fixed-point gemstones , the bigger the turntable and the closer it is to the outer ring, the more obvious the beating will be. This kind of beating phenomenon is difficult to control and eliminate, which has a great impact on the quality of polishing and is difficult to control the quality of finished gemstones. In addition, because the grinding head is a single grinding head, each time only Can polish a gemstone on an aluminum row, with a lower yield
