AI Technical Summary

Technical Problem

The existing ball screw assembly process is inefficient and difficult to achieve mass production. There are also problems such as ball jamming, ball leakage, and ball falling, which affect assembly stability and qualification rate.

Method used

The screw is loaded by adopting multiple rotary storage positions. Combined with the turning frame, rotary chuck, manipulator and ball sweeper, the precise alignment of the screw and nut and the precise feeding of the balls are achieved. The rotary lifting mechanism realizes the alternating cycle operation of multiple positions, thus improving the assembly efficiency and precision.

Benefits of technology

The batch assembly of ball screw pairs is realized, the problem of ball sticking is reduced, the assembly efficiency and qualification rate are improved, and the stability and integrity of the assembly are ensured.
