Abstract

The invention discloses a full-automatic arc concave gem grinding machine, which comprises a rack. A transverse mounting frame is rotatably arranged at the upper side of the rack; a plurality of longitudinal aluminum ranks for clamping gem blanks are fixedly arranged on the bottom part of the mounting frame in parallel; a locking block for fixing the position of the mounting frame is arranged at the upper end of the mounting frame; guide slots are arranged at the left end and the right end of the lower side of the frame; supporting plates the two sides of which are provided with guide rails are arranged in the guide slots; the supporting plates are rotatably provided with a plurality of rotating shafts which are arranged in parallel in front and rear directions; grinding rods are fixedly arranged on the rotating shafts; guide seats are arranged at the bottom parts of the supporting plates and are provided with transverse screw holes in left and right directions; screws are sheathed inthe screw holes; the other ends of the guide seats are connected with connecting bars; longitudinal through holes are arranged at the right ends of the connecting bars; the connecting rods are connected with transverse eccentric slot wheels through the through holes; longitudinal screw holes are arranged at the middle positions of the supporting plates; lifting screws matched with the longitudinal screw holes in motions are arranged in the longitudinal screw holes; longitudinal guide holes are arranged at the two sides of the supporting plates; and guide rods are respectively sheathed in the guide holes and are arranged on the frame.

Description

technical field [0001] The invention relates to a processing machine for jewelry blanks, in particular to a full-automatic curved concave gemstone grinding machine which integrates rough grinding, fine grinding and polishing. Background technique [0002] Due to the continuous improvement of living standards, people have put forward higher requirements for jewelry appreciation. At present, the facet grinding processing of all crystal and gemstone jewelry on the market is basically dominated by plane grinding. As far as the visual ornaments are concerned, the arc-shaped grinding ornaments have a higher optical refractive index and appreciation. At present, there are only a small number of arc-shaped gemstones processed by hand grinding in the market, and the quality and output of the processed ornaments are far from meeting the market demand, and the facets of crystal ornaments basically do not have arc-shaped faces. Contents of the invention [0003] In view of the above ...
