AI Technical Summary

Technical Problem

During the tightening process of the cylinder block and cylinder head, a large amount of impurities and dust on the outer surface affects the tightening effect of the screw, and the cylinder block is prone to shake during the tightening process, resulting in the reduction of the screw installation accuracy.

Method used

An automatic tightening machine for engine cylinder head screws is designed, including a load bearing mechanism, pressing assembly, limiting assembly and moving mechanism. It is designed to reduce the influence of dust by vacuuming, flexible fixing and contact fixing, and mark the screw sequence and transportation cylinder through the clamping assembly to improve tightening accuracy.

Benefits of technology

Effectively remove dust from the cylinder block and cylinder head surface, reduce the impact of dust on tightening, prevent cylinder block from shaking, and improve the accuracy and working efficiency of screw installation.
