Abstract

In order to solve the problem that in the prior art, after a complex connecting rod unlocking mechanism is assembled, a driving rod piece is located in a shell, and the angle of the driving rod piececannot be measured, the invention provides a driving rod piece angle measuring tool of the complex connecting rod unlocking mechanism. The measuring tool comprises a mounting platform, a latch hook swing angle testing assembly, a latch hook positioning mechanism, a rocker swing angle testing assembly, a connecting rod and a locking mechanism. The latch hook swing angle testing assembly, the latchhook positioning mechanism and the rocker swing angle testing assembly are all arranged on a bottom plate of the mounting platform. One end of the connecting rod is connected with a driving end of a rocker arm connected with the to-be-tested unlocking mechanism, and the other end is connected with one end opposite to the handheld part of the handle, and the connecting rod, the handle and the rocker arm form a parallelogram mechanism. The invention further provides a method for measuring the angle of the driving rod piece through the measuring tool. Through using the parallelogram mechanism, the swing angle of the driving rod piece which cannot be measured in the shell is led out of the shell to be measured, and the angle of the driving rod piece is measured before assembly.

Description

technical field [0001] The invention relates to the field of aviation repair, in particular to an active rod angle measuring instrument and a measuring method thereof when the lock hooks of a complex connecting rod unlocking mechanism are in different states. Background technique [0002] The structure of an assembly such as figure 1 As shown, it is a multi-link mechanism composed of welded brackets, lock hooks, rocker arms, connecting rods and springs. Due to the complex structure of the assembly, the assembled rear rocker arm (an active rod) is inside the housing, and its swing angle cannot be measured, making it difficult to guarantee the main performance of the assembly, which in turn will affect the qualification rate of component debugging. [0003] At present, in the assembly process of the assembly, the size of each part is usually guaranteed first, and then the overall performance of the assembly is measured after assembly. Since the rocker arm is inside the shell,...
