AI Technical Summary

Technical Problem

In the process of loading automobile wheel hubs, the existing vacuum coating equipment is cumbersome and inefficient to operate manually. Furthermore, the adjusting thread rod of the positioning fixture lacks a reliable locking mechanism, which can cause the positioning block to retract unexpectedly due to equipment vibration or accidental contact, affecting the gripping accuracy of industrial robots and production stability.

Method used

The mechanical locking structure of ratchet and pawl, combined with a chain conveyor belt driven by a servo motor, ensures that the positioning cylinder remains in an expanded state during conveying by the meshing of the pawl and ratchet, preventing unnecessary closing and providing stable radial positioning.

Benefits of technology

It prevents the positioning cylinder from closing when the equipment vibrates or is accidentally touched, ensuring the stability and precise positioning of the wheel hub during the conveying process, and improving the accuracy of industrial robot grasping and the stability of automated production.
