Description

Round aviation plug rear accessory dismounting tool

Technical Field

The present utility model relates generally to the field of aircraft connectors, and more particularly to a circular aircraft plug rear attachment removal tool.

Background

At present, two main methods are available for removing the accessories after the circular aviation plug in China: 1. a screwdriver or other tools are used for supporting a main key in the plug, so that the inner core of the plug cannot rotate, and then the rear accessory is removed; 2. after the socket corresponding to the plug is used for butting, the inner core of the plug cannot rotate, and then the rear accessory is removed. The first method is easy to damage the main key of the plug, so that the plug is scrapped; the second method requires corresponding sockets during disassembly, however, most of each shell of the circular aviation plug is provided with 5-6 different key positions, so that different sockets are required to be matched with the corresponding sockets, and if all kinds of sockets are required to be assembled, the cost is high and the engineering application is complicated.

Disclosure of Invention

In order to solve the above problems, the present utility model provides a tool for removing a rear attachment of a circular aviation plug, comprising: the simulation socket 1 and the interface base 2 are characterized in that the shell of the simulation socket 1 is cylindrical, the outer diameter is smaller than the inner diameter of the aviation plug shell, the inner diameter is larger than the outer diameter of the inner core of the aviation plug, and the inside is of a multi-key groove structure and is used for fixing the inner core of the aviation plug; 4 threaded holes are formed in the upper end face of the interface base 2, and the analog socket 1 is fixed; the depth of the internal key groove of the simulation socket 1 is larger than the distance from the end face to the bottom of the aviation plug; the simulation socket 1 is in clearance fit with the aviation plug shell and is in clearance fit with the aviation plug inner core; the circular side wall of the interface base 2 is provided with a penetrating circular hole; the center of the interface base 2 is provided with a square mounting hole 3 for mounting a torque wrench 5.

Preferably, the materials of the analog socket 1 and the interface base 2 are composite materials.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model. Except for this example, devices similar to the examples of the present utility model in the industry and in the field are within the scope of the present utility model.

The circular aviation plug as shown in fig. 1 includes: 1. simulating a socket; 2. an interface base. The analog socket 1 is used for fixing the plug inner core, so that the plug inner core is prevented from rotating when the plug is assembled and disassembled, and 6 different key slot structures can be synthesized for each type of analog socket 1; the upper end surface of the interface base 2 is provided with 4 threaded holes for fixing the analog socket 1, the interface is further provided with an interface for installing a straight rod and a torque wrench 5, the circular side wall is provided with a through round hole, and the straight rod 4 passes through the round hole, so that an operator can conveniently hold or rotate a tool; the interface base 2 is provided with a square mounting hole 3 for mounting a torque wrench; the material of the analog socket 1 and the interface base 2 is aluminum alloy or composite material, so that keys in the plug are not damaged.

The outer diameter of the simulation socket 1 is smaller than the inner diameter of the aviation plug shell, the inner diameter is larger than the outer diameter of the inner core of the aviation plug, and the depth of the internal key groove is larger than the distance from the end face of the aviation plug to the bottom; the analog socket 1 is in clearance fit with the aviation plug outer shell and is in clearance fit with the aviation plug inner core.

As shown in fig. 1, the utility model comprises a simulation socket 1 and an interface base 2, wherein the simulation socket 1 is provided with key grooves which can be matched with different key positions of a round aviation plug, when in use, main keys in the simulation socket 1 are aligned with main keys in the plug and inserted, and the key grooves in the simulation socket 1 can clamp the keys in the plug, so that the plug inner core cannot rotate; at the moment, the plug is screwed or unscrewed, and then the accessory is attached; if the screwing or unscrewing torque is larger, as shown in fig. 2, a straight rod 4 can be inserted into the interface base 2 to assist in improving the rotation torque; if the torque of the accessory is required to be installed after the test, a torque wrench is installed on the interface base 2, and the tightening torque is tightened and tested as shown in fig. 3.
