Locking nut assembling tool assembly for aircraft actuator cylinder maintenance

Abstract

The invention discloses a locking nut assembling tool assembly for aircraft actuator cylinder maintenance. The locking nut assembling tool assembly comprises a sleeve, four positioning claws are arranged at the lower end of the sleeve, positioning through holes are formed in the side face of the upper end of the sleeve, and the positions of the positioning through holes correspond to the positions of the positioning claws up and down; and a connecting rod is arranged in the sleeve in a sleeved mode, a first through hole with an opening in the upper end is formed in the connecting rod, a groove is further formed in the side face of the top end of the connecting rod, a side through hole is formed in the side face of the lower end of the connecting rod, the groove and the side through hole vertically correspond to each other in position, a positioning ball is further arranged in the side through hole, and a pin rod is horizontally inserted into the positioning through hole. Compared with the prior art, the locking nut assembling tool assembly has the beneficial effects that during installation, the positioning ball is clamped in the safety hole of a safety lining, then the sleeve is arranged outside the connecting rod in a sleeving mode, after the sleeve is rotated, when the positioning through hole is opposite to the groove in position, the pin rod of an indicating pin can penetrate into the groove and the first through hole, and at the moment, the safety groove corresponds to the safety hole in position; therefore, the assembly of the piston locking nut is quickly completed.

Description

technical field [0001] The invention relates to the technical field of aircraft actuator repair, in particular to a locking nut assembly tool assembly for aircraft actuator maintenance. Background technique [0002] When assembling the locking nut and other components inside the cylindrical piston of the actuator, firstly, the safety bushing is positioned on the piston rod through the key protruding from the bottom, and it is kept relatively still. The outer wall of the safety bushing is set There are seven safety holes. Then the locking nut is installed on the thread at the end of the piston rod, and the upper end of the safety bushing is limited and fixed, and the piston safety nut is a nut with four safety grooves. The torque requirement during installation is 112-168N.m, and according to the needs of subsequent installation, after installation, a safety groove on the lock nut must be completely aligned with a safety hole on the safety bushing, so that the subsequent Th...

AI Technical Summary

Problems solved by technology

[0004] The technical problem solved by the present invention is to overcome the inconvenient alignment between the safety hole of the safety bush and the safety groove of the locking nut when assembling the internal parts of the cylindrical piston in the prior art, and to provide a locking device for aircraft actuator maintenance. A nut assembly tooling assembly, the lock nut assembly tooling assembly for aircraft cylinder maintenance can make the safety hole of the safety bushing align with the safety groove of the lock nut when the internal parts of the cylindrical piston are assembled without Visual inspection and inspection, automatic alignment, improve assembly speed and efficiency
