Description

Technical Field

[0001] The utility model relates to the technical field of pearl grinding, in particular to an automatic pearl grinding tooling and a full-automatic pearl grinding device. Background Art

[0002] The existing pearl grinding equipment is an upper and lower profiling grinding wheel tool, which drives the upper profiling die to rotate by a motor, and at the same time applies a certain force to the upper profiling die by using the lever principle. The pearl is ground in the slideway groove of the profiling die. When grinding for a certain time, the pearl is taken out for measurement and classification.

[0003] However, this kind of grinding equipment has the following defects:

[0006] 3) The sizes of the ground pearls are different and the grinding times are different, but all these require experience, so not everyone can operate simply. Due to the differences in the experience and capabilities of the personnel, the roundness and smoothness of the ground pearls are different;

[0007] 4) The existing market equipment is relatively simple and the safety cannot be guaranteed.
