Problems solved by technology

[0003] Due to the extremely narrow space of the N2 high-pressure speed sensor, the sensor is fixed with a round nut, and the common tools are too large to be disassembled and assembled effectively.
Commonly used socket wrench, the socket cannot be inserted into the slotted hole of the fixing nut
Commonly used open-end wrench, can not add force to the slot hole

Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and technical solutions.

[0023] A special tool for disassembly and assembly of aircraft sensors, such as figure 1 As shown, including movable tooth 1, torsion spring 2, positioning pin 3 and fixed tooth 4; as figure 2 It is the specific figure of the active tooth, such as image 3 It is the specific figure of the fixed tooth.

[0024] The movable tooth 1 and the fixed tooth 4 are connected by a positioning pin 3, and the opening and closing angle of the two is adjusted by a torsion spring 2;

[0025] The fixed tooth 4 is an integral structure composed of the left end and the right end handle, on which there are positioning pin holes and torsion spring fixing holes near the left end; the left end is used for fixing the nut, and the arcs of the inner and outer edges are different Center, the arc center distance is 5mm, this design can effecti...

Abstract

The invention belongs to the technical field of aviation, and provides a tool special for disassembling and assembling an aircraft sensor. The tool comprises a movable tooth, a torsional spring, a positioning pin and a fixed tooth; the movable tooth and the fixed tooth are connected through the positioning pin; and the opening and closing angle thereof is adjusted through the torsional spring. The special tool disclosed by the invention has a spring adjusting function and can ensure that a round nut is continuously stressed. The operation is convenient; and the nut can be inserted into a round nut groove hole and rotated. By means of the automatic reset principle of the torsional spring, when the special tool is used for disassembling and assembling, the movable tooth adjusts the stress point of the nut to guarantee that the nut is continuously stressed when the tool rotates. The tool is simple in structure and ingenious in design; and the size movable tooth and the fixed tooth are connected by using a cambered surface, so that the size of the tool is reduced, and it is guaranteed that the tool is attached to the round nut. In order to guarantee reduction of concentrated stress, a destressing arc surface is specially designed at the stressed part of the movable tooth.

Description

technical field [0001] The invention belongs to the technical field of aviation and relates to a special tool for disassembling and assembling an aircraft sensor. Background technique [0002] According to the requirements of the aircraft overhaul process, the N2 high-pressure speed sensor in a certain type of aircraft engine must be calibrated regularly, so disassembly and assembly of this sensor is a must. Due to the narrow space in the engine compartment, the space of the N2 high-pressure speed sensor is extremely small. The sensor is fixed with a round nut. When the round nut is disassembled, only the slot hole on the nut can be applied with force. Common tools are too large to be disassembled effectively. , so there is an urgent need for a special disassembly tool to apply force to the slot hole, and at the same time it needs to be able to work continuously and disassemble the sensor in a short time. The shortcoming of prior art and technical problem to be solved by th...
