AI Technical Summary

Technical Problem

Aero engine parts are prone to cracks and breakage of lead seals during the lead sealing process. The prior art is difficult to effectively protect lead seals, resulting in damage caused by the lock wires being wound.

Method used

A lead seal tool for engine parts is designed, using a clamping head and a stop pin structure, and the two lock wires are penetrated through the opening of the lead sealing block, and the lock wires are avoided from being wound through the blocking effect of the stop pin, and the bonding limit is limited. The positioning pin and guide pin are used to precisely control the thickness and position of the lead seal block.

Benefits of technology

It effectively improves the protective performance of the lead seal block, avoids cracks and breakage caused by the entanglement of the lock wire inside the lead seal block, and ensures the integrity of the lead seal block and the efficient quality of the lead seal.

Abstract

The invention relates to the lead sealing technology of aircraft engine parts and discloses a lead sealing tool and a lead sealing method for engine parts. A lead sealing block is clamped in a clamping head, and two groups of stop pins are arranged on the second clamping head of the clamping head, wherein the lead sealing block is between the two groups of stop pins, and the two groups of stop pins are arranged at openings on both sides of the lead sealing block, so that two lock wires respectively pass through the openings on both sides of the lead sealing block in sequence, and the two ends of the two lock wires are tightened to be entangled with each other. When they are wound to the stop pins, due to the blocking effect of the two groups of stop pins, the two lock wires inside the lead sealing block do not need to contact, thereby effectively improving the protection of the lead sealing block and avoiding the cracks and breakage of the lead sealing block caused by the lock wires being entangled inside the lead sealing block after the two lock wires are tightened.
