Double-concave-surface pearl same-direction positioned drilling method

Abstract

The invention discloses a double-concave-surface pearl same-direction positioned drilling method, and belongs to the field of pearl design. In the double-concave-surface pearl same-direction positioned drilling method, through arrangement of a concave-surface polishing mechanism, pearls are transversely positioned through recess spherical surfaces on two concave-surface positioning columns beforepunching; under the effect of four soft positioning bags, the pearls are guaranteed in the center of the two recess spherical surfaces; meanwhile, a drilling module is arranged in the center of the concave-surface positioning columns and parallel to the concave-surface positioning mechanism, so that the punching direction is parallel to clamping and fixing force of the pearls, the stability of thepearls is effectively improved, the pearls are not easy to deviate due to the punching force, and the pearl punching quality and success rate are effectively guaranteed; and meanwhile, through arrangement of dual-purpose collecting slide ways, the punched pearls can be collected, and pearl powder generated by punching can be collected, so that the waste of pearl resources is effectively reduced,and the use efficiency is improved.

Description

technical field [0001] The invention relates to the field of pearl design, in particular to a double-concave pearl co-directional positioning drilling method. Background technique [0002] Pearl is an ancient organic gemstone, mainly produced in the molluscs of pearl shellfish and mother-of-pearl shellfish; and the calcium carbonate-containing mineral (aragonite) beads produced by endocrine action are composed of a large number of tiny aragonite crystals Assembled; rich in variety, different shapes and colorful colors; according to the research of geology and archeology, there were already pearls on the earth 200 million years ago. Pearls with magnificent colors and elegant temperament symbolize health, purity, wealth and happiness, and have been loved by people since ancient times. Pearls are also divided into freshwater pearls and seawater pearls. [0003] Pearls come in a variety of shapes, including round, pear, egg, teardrop, button and random shapes, among which the ...

AI Technical Summary

Problems solved by technology

[0004] When the existing pearls are drilled, the pearls are usually positioned first, and then a drill bit perpendicular to the force direction of the pearls is set from top to bottom to drill holes. However, since the pearls are spherical, the stability is relatively poor. When punching, the force perpendicular to the clamping direction will easily cause the pearl to shift downward along the direction of punching, making the stability of the pearl poor, which will easily lead to shifting when punching, making the punching efficiency lower Low
