A Precise Numerical Control Double Grinding Head Gem Rolling Forming Machine

Abstract

The invention discloses a precision numerically controlled gem barreling former with double grinding heads. The former comprises a grinding system and a driving system, the grinding system comprises the grinding heads, each grinding head comprises a feed movement mechanism, a swing angle mechanism, a turn angle mechanism, a lifting mechanism and a pneumatic mechanism, each pneumatic mechanism is mounted on an aluminum row seat and used for clamping an aluminum row, each feed movement mechanism is arranged on a grinding head bottom plate, each lifting mechanism is mounted on a base, a lifting motor drives each whole grinding head to vertically move, and each swing angle mechanism and each turn angle mechanism are mounted on a support and used for swinging and turning the aluminum row. The former is characterized in that the grinding system further comprises a grinding roller axially parallel to the aluminum row, the grinding roller is connected with the driving system, the two grinding heads are correspondingly arranged on two sides of the grinding roller, and the aluminum row is matched with the grinding roller. The former has the advantages of uniform grinding amount, size consistency of grinded finished gems, high grinding quality and high yield.

Description

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
