AI Technical Summary

Technical Problem

Existing clamping devices are difficult to be compatible with gourds and beads of different sizes. During processing, the workpiece angle needs to be adjusted frequently by hand, which is inefficient and makes it difficult to ensure processing consistency.

Method used

The lifting mechanism, driven by a threaded rod and a first motor, achieves micro-adjustment of the lifting block through gear meshing. Combined with the corresponding design of the upper and lower conical top rods, it achieves dual fixation of the top of the gourd or bead by pressing down and limiting, and bottom support.

Benefits of technology

It achieves stable clamping of gourds or beads, preventing slippage and displacement during processing, thus improving processing stability and accuracy. It is suitable for uniform pressure application on irregular curved surfaces and dynamic grinding of beads, and the device has strong versatility.
