Method for installing connecting rod bolts

摘要

A fixture and mechanism for guiding and installing body bound bolts in the bolt openings of engine connecting rods and the like. The device uses an air cylinder to advance an impact hammer driving push rods to engage the bolts. The air cylinder applies only a moderate force sufficient to advance the impact hammer to a position to impact the bolts. The impact force of the pneumatic air hammer is required to advance the bolts into press fitting engagement within the connecting rod openings. The method of using impact forces to drive the bolts into press fitting engagement while advancing the impact hammer with a lower force air cylinder accomplishes installation of the bolts with a relatively small and low cost fixture and equipment as described.
