AI Technical Summary

Technical Problem

In the existing balance shaft drilling and fixing fixture, iron filings are easily embedded in the gap between the positioning table and the balance shaft during the machining process, resulting in positioning errors, affecting machining accuracy and operational safety, and making cleaning difficult.

Method used

A stop box is set between the positioning platforms, and a cleaning brush that can automatically reciprocate is installed on both sides of the positioning platform. The cleaning brush is driven by the loading and unloading action of the balance shaft to remove iron filings. Combined with the airtight door and drive assembly, closed cleaning is achieved. The opening and closing of the airtight door is controlled by the detection sensor to ensure that iron filings do not splash.

Benefits of technology

It enables automatic and efficient cleaning of metal scrap, improves processing accuracy and operational safety, reduces maintenance costs, and ensures positioning accuracy and production efficiency.
