AI Technical Summary

Technical Problem

Existing shaft-type machining cages have poor stability when fixing the shaft, which can easily cause the shaft to deviate, affecting machining accuracy. Furthermore, threaded connections are prone to slippage, causing the shaft to fall off.

Method used

The shaft is fixed by a conical head and a rubber ring, and stable fixation is achieved by sliding inside the conical box. The positioning component is used to position the connection between the outer rod and the threaded rod, reducing the pressure at the connection and preventing slippage.

Benefits of technology

It improves the stability of the shaft, prevents shaft deviation, ensures machining accuracy, and prevents it from falling off. It also improves the stability of the connection structure at the threaded connection, achieving stable shaft fixation and ensuring the machining accuracy of the shaft.
