AI Technical Summary

Technical Problem

During the spraying process, the paint seeps into the lead screw and bushing structure through the gap between the top block and the ball valve, which increases the resistance to the rotation of the lead screw and makes the top block slide poorly, resulting in work jamming.

Method used

The threaded rod limiting mechanism includes a threaded sleeve, a guide frame, and a top block. The threaded sleeve is connected to the threaded rod. By utilizing the synchronous rotation of the reinforcing rod and the drive disc, the slider slides along the guide frame, and the connecting rod drives the top block to slide. Multiple top blocks self-center, and the protective block seals the threaded rod to prevent paint from seeping in.

Benefits of technology

It reduces the interference of coating on the threaded sleeve and threaded rod, ensures the normal use of tooling, is suitable for ball valves of different sizes, the protective block is removable and replaceable, and has a good sealing effect.
