Technical Field
The invention belongs to the technical field of aviation, and relates to a special tool for disassembling and assembling an aircraft sensor.
Background
According to the requirements of the aircraft overhaul process, the N2 high-pressure rotating speed sensor in a certain type of aircraft engine must be periodically verified, so that the sensor must be assembled and disassembled. Because engine compartment space is narrow and small, and N2 high-pressure speed sensor space is unusual narrow and small, and this sensor uses circular nut fixed, can only carry out the afterburning to the slotted hole on the nut during circular nut dismouting, and the instrument of commonly using is bulky, can not effective dismouting, so need special assembly and disassembly tools urgently, to the slotted hole afterburning, need can continuity of operation simultaneously, with this sensor dismouting in the short time. Disadvantages of the prior art and problems addressed by the present invention
Because N2 high-pressure speed sensor space is unusual narrow and small, this sensor uses the circular nut fixed, and the instrument of commonly using is too big, can not effective dismouting. With a conventional socket wrench, the socket cannot be inserted into the slot of the fixing nut. The common open spanner can not apply force to the slotted hole. Therefore, a special spanner needs to be designed, the size cannot be overlarge, the structure cannot be complex, and force can be applied to the circular nut slot hole. Therefore, the special tool adopts the arc surface eccentric design, the arc surface is ensured to be attached to the round nut, and the eccentricity is used for reducing the size of the tool. The continuous operation requirement is required to be met for the tool, the nut needs to be rapidly disassembled and assembled, the special spring is selected for the special tool, and the fact that the tool continuously applies force to the nut in the rotating process is guaranteed.
