Description

Power-assisted plug pliers

Technical Field

The invention belongs to the technical field of assembly, and relates to a plug clamp used for butting and disassembling an aviation plug, which is used for assisting in butting or disconnecting the plug, has universality and can be automatically adjusted according to the size of the plug.

Background

When the aircraft is butted on an airplane, due to some special positions, the aviation plug can be fastened only by finger force, and the wrist cannot apply force, so that the fastening is difficult; similar problems exist when the butt plug is disconnected, sometimes, due to small strength or inconvenient force application of a detacher, one plug needs to be detached for dozens of minutes or even dozens of minutes, and the traditional tool is inconvenient to use due to space limitation.

Based on the technical scheme, the plug pliers are used for assisting in butt joint and disconnection of the plug, so that manpower and period are saved, the labor intensity of an operator is reduced, and the assembly work can be finished with guaranteed quality.

Disclosure of Invention

In order to solve the problems, the invention provides a set of universal power-assisted plug pliers according to the appearance characteristics of an aviation plug, which is small, exquisite, light, convenient to carry and convenient and quick to use.

The technical scheme of the invention is as follows:

a power-assisted plug pliers comprises a handle, a rotary cone 3, a forward switch 4, a reverse switch 5, a rubber band 6, a shaft disc 7, a fixed claw 8 and a threaded column 9.

The handle is integrally cylindrical and comprises a handle tail end 1 and a handle front end 2. The tail end 1 of the handle is used for being held by hands, and can rotate 90 degrees relative to the front end 2 of the handle, so that the handle can be used in an I shape or an L shape, and a sheltering object on the machine can be conveniently sheltered. The front end 2 of the handle is fixed at the front end of the tail end 1 of the handle, and a battery and a motor are arranged inside the front end 2 of the handle and used for driving the rotary threaded column to rotate; the outer surface of the front end 2 of the handle is provided with a forward switch 4 and a reverse switch 5 which respectively control the forward rotation and the reverse rotation of the motor.

The rotating cone 3 is conical and is hollow inside; the rotating cone 3 is coaxial with the front end 2 of the handle, the bottom surface of the rotating cone 3 is attached to the surface of the front end 2 of the handle in an embedded track mode, and the rotating cone 3 rotates around the central shaft of the rotating cone 360 degrees on the outer surface of the front end 2 of the handle.

The threaded column 9 is cylindrical, and the outer surface of the threaded column is provided with a forward thread or a reverse thread which is selected according to the requirement of the rotating direction. The threaded column 9 penetrates through the centers of the shaft disc 7 and the rotating cone 3 to be connected with a motor in the front end 2 of the handle and is driven to rotate by the motor. The center of the shaft disc 7 is provided with a thread which can move on a threaded column 9.

The shape of the fixed claws 8 is similar to a bow shape, and the three fixed claws 8 are distributed at intervals of 120 degrees. The front end of the fixed claw 8 is carved with a tooth mark for clamping a plug; the middle part of the fixed claw 8 is fixed on the shaft disc 7 and can rotate along with the shaft disc 7 by taking a fixed point on the shaft disc 7 as a shaft; the outer side of the tail end of the fixed claw 8 is provided with a groove for nesting the rubber band 6, and the tail end of the fixed claw 8 can be attached to the conical surface of the rotating cone 3 in any state.

When the plug is used, firstly, the plug is grabbed by the three fixing claws 8, the switch (the forward switch 4 or the reverse switch 5) is pressed to enable the motor to drive the threaded column 9 to rotate, the shaft disc 7 rotates along with the rotation and gradually moves along the threaded column 9 to be close to the rotating cone 3, after the fixing claws 8 approach the rotating cone 3 along with the shaft disc 7, the tail ends of the fixing claws 8 are guided to upwarp due to the narrow upper part and the wide lower part of the conical surface of the rotating cone 3, and the front ends of the fixing claws 8 are further pressed downwards to thoroughly lock the plug; at the moment, the tail end of the fixed claw 8 cannot move forward continuously, the rotating cone 3 is driven to rotate together, and then the fixed claw 8 locks the plug to rotate together, so that the aim of butting or disconnecting the plug is fulfilled, and the operation is finished instantly under the condition of no labor; finally, the plug can be released only by pressing the other switch (the reverse switch 5 or the forward switch 4).

The invention has the beneficial effects that: the invention provides a power-assisted plug pliers, which effectively shortens the period of butt joint or disconnection of a plug, can complete the original work of tens of minutes or even tens of minutes in only a few seconds, reduces the labor intensity of an operator, ensures that the butt joint and disconnection of the plug are not laborious, and effectively ensures the product quality and the production task node of an airplane; meanwhile, the professional technical level is improved, the testing process is optimized, and higher economic and social benefits are generated for scientific research and production.
