Description

Electronic cabin actuator cylinder axial lead alignment frock Technical Field The utility model relates to the technical field of repair of butterfly valve actuating cylinders in electronic cabins of civil aviation aircrafts, in particular to an aligning tool for the axial lead of an electronic cabin actuating cylinder. Background In the ventilation system of the electronic cabin of the airplane, the V2T series butterfly air valves play a key role in removing overheated air and playing a role in cooling. The valve actuator is prone to failure due to its high switching frequency and harsh operating environment. In the prior art, in the process of assembling the valve actuator, the actuator worm wheel and the worm are difficult to install. Once the center line alignment is deviated, abnormal abrasion of gears on the surfaces of the worm disk and the worm can be caused, and the butterfly-shaped air valve becomes unreliable in the running process of the airplane. At present, a special tool capable of adjusting the alignment of the center line of the worm disk and the worm of the valve actuator is lacking in China.
