Throttle lever test frame

Abstract

The invention belongs to aircraft maintenance tooling, in particular to throttle lever maintenance. A kind of throttle lever inspection type frame, its technical proposal is: the bracket (4) is divided into two parts, separated on both sides of the type frame, the bracket (5) is hinged on the upper part of the bracket (4) through the shafts (52) at both ends; The hole stringer (7) is connected with the long hole (42) in the middle part of the bracket (4); the non-hole stringer (8) is connected with the round hole (43) in the lower part of the bracket (4); the oblique support (1) and the straight support The seat (2) is assembled with the pulley (6) respectively into an oblique pulley assembly at 45° to the horizontal plane and a straight pulley assembly parallel to the horizontal plane, and is fixed on the perforated stringer (7) as required; the stop pin (3) is inserted in the On the through hole that coincides with the bracket (5) on the bracket (4). The application of the invention can effectively check the assembly correctness of the throttle lever before the throttle lever is installed on the aircraft, and compared with the prior art, the production cost is reduced and the working efficiency is improved.

Description

technical field [0001] The invention belongs to aircraft maintenance tooling, in particular to throttle lever maintenance. Background technique [0002] The structure and principle of the throttle lever used on two types of aircraft are similar, and they are all composed of brackets, left and right joysticks, guide rods, braking devices, pulleys, steel cables, etc. In addition to ensuring the correctness of the throttle lever after repair, it is also necessary to ensure the clearance between the cable and multiple parts. There are multiple steel cables (8 at most) wrapped around the throttle lever, and the steel cables have certain elasticity, and will pop out of the pulley groove under the condition of no force, so it is difficult to see the correctness of the cable winding. In particular, one of the models has two throttle sticks that need to work in harmony, and it is more difficult to see the correctness of a single throttle stick. In addition, the steel cable is slack...

AI Technical Summary

Problems solved by technology

There are multiple steel cables (the most is 8) wrapped around the throttle lever, and the steel cables have a certain degree of elasticity, and will pop out of the pulley groove under the condition of no force, so it is difficult to see the correctness of the cable winding

Especially one of the models has two throttle sticks that need to work in harmony, it is more difficult to see the correctness of a single throttle stick

In addition, the steel cable is slack when it is not stressed, and there is no way to check the gap between the steel cable and other parts

At present, when checking the gap, two people need to coordinate their work: one person pulls the steel cable hard, and the other checks the gap. Due to the limited manpower, the gap inspection is not accurate

This greatly affects the quality of work and increases production costs
