Shell and movement decomposition device of airplane pyrometer

Abstract

The invention discloses a shell and movement decomposition device of an airplane pyrometer, and belongs to the technical field of aviation repair. The shell and movement decomposition device comprisesa base, a first support, a second support, a clamp ring, a screw and an annular copper pipe type welding ring. The first support is fixed to the base, and the airplane pyrometer is horizontally fixedto the first support. The second support is fixed to the base. The clamp ring is mounted in a through hole of the second support in a sleeved manner. The end, away from the airplane pyrometer, of theclamp ring stretches out of the second support. The screw and the clamp ring are in threaded fit. When the screw axially moves to the position of a movement plug of the airplane pyrometer, a clamp sleeve of the screw cooperates with the movement plug of the airplane pyrometer. The annular copper pipe type welding ring is mounted to the welding position of a shell and a movement of the airplane pyrometer in a sleeving manner and is connected with high-frequency induction heating equipment. Efficient and safe decomposition of the welding position of the shell and the movement of the airplane pyrometer can be achieved.

Description

technical field [0001] The invention belongs to the technical field of aviation repair, and in particular relates to a shell and watch core decomposition device of an aircraft exhaust temperature meter. Background technique [0002] In order to ensure the airtightness of the aircraft exhaust temperature gauge, the shell and the watch core are welded and sealed. In the maintenance process, it is necessary to disassemble the temperature meter casing to repair its internal structure, and use heating to melt the solder to decompose the casing and watch core. [0003] The current disassembly technology is to use a ring-shaped electric soldering iron to melt the solder at the welding point between the shell and the watch core through conduction heating, and then use hand-held needle-nose pliers to pull the watch core out of the shell. The shortcoming of this decomposition method is: the first, because electric soldering iron heating speed is slow, decomposition time is long. Sec...

AI Technical Summary

Problems solved by technology

The disadvantages of this decomposition method are: first, because the heating speed of the electric soldering iron is slow, the decomposition time is long

Second, conduction heating heats the exhaust temperature meter casing, watch core, circuit board, and plug at the same time; overheating can easily cause the plug and circuit board connection wires to fall off, the circuit board pins to be connected falsely, and the precision parts inside the exhaust temperature meter to be deformed and other damages

Third, it is inconvenient to separate the watch movement by hand

Fourth, the decomposition method takes an average of 1h, and the decomposition time is long
